T400 box will end up full manual and prob with trans brake

100 shot of gas for the strip may be on the cards later also.

Q. What diff ratio and what size stall would suit the combo?

Later on you will want more power. So if you dont want to change everything again later.
28" slicks, 3.73s are good for 140mph. 4000 stall is probably a good balance or maybe up to 4500rpm. Initially you can use 26" slicks and be a little lower geared.

[calais-346]

i'd go 3.9's on a 26 inch slick, with that combo you'll go 120-125mph i'd reckon which will put you in the 6300 to 6800rpm range (including some trans slip)
Like oztrack said if you get some more power you can go up to 28 inch slicks(140 mph 6600-7100rpm) which will give you a larger footprint too.

4500 converter

You'll go slower with the TH 400 than you would if you threw a 4L65E in, but i guess your looking to future proof the car??

[Oztrack Tuning]

The research ive done thats not necessarily the case. The Turbo 400s have a better ratio spread for drag racing and if the stall is big enough - the more power the engine has the taller you need to go and that doesnt mean slower 60 footers.

Turbo400s can be built to be very efficient with lightened parts etc.

[Maloo03]

I have 3.73 spare diff here so maybe a 4500 stall on a 26 inch slick and if need be run taller for the gas when installed. T400 is for the strength and I have one here so I will use whats available to me because of the budget.

Thanks Brad

Question One ? Why 3 speed box for such a little cam :confused:

Question Two ? Why transbrake..well proven they do diddly squat for anything under 400rwkw..or 480rwkw DD

Question three . if your chasing 1.4 sixty footers or below NA start with 6K TC and 4.11's then work backwards as experince guides you to where you want to go

Untill the above is well and truly sorted and your crossing the line at 7K in third with the A4 Box , then 100HP of Nos is not going to work any magic numbers..

At your power level calais-346 is right on the numbers ...stick with a 26 inch tyre ..235 MT DR's will be your best bet imho


Just my take and opinion..........if your already runing 1.4 Low sixty fts NA then please discard all above comments.

.

[Oztrack Tuning]

Mark is right if you arent going to give it a lot more power in the future. Transbrake will be almost useless until a 9" diff with suspension setup for it is installed. Also true about the 26" MT 235 x 15s when only going 1.50 plus. Markone2 has done <1.5 which is awesome but not many here or the usa have done the same without bigger tyres. 275/50 x 15s are the DR that has done the most in the USA in GTOs and various sizes of 28" slicks.

[Maloo03]

This is all great information. thanks

I have a t400 so I will use it

I have the 3.73 diff so I will probably use it for now

Stall is the issue, as it will not be just a drag racing car it will have coil overs and also be able to run street sprints with it manualized and hill climbs. Stripped car so guessing 1500kg not sure on the sums to work out rpm gears and hp and what stall would be a great alrounder?

thanks steve.mark.luke for ya advice it is helpfull

I agree with what the others have said, 4.11 ratio, 26" tyre and forget the transbrake, they dont work with IRS cars.
If you use the TH400 for the super sprints DONT use the auto to slow the car as you'll kill the box quickly.

Also agreed!.. Get the transbrake and throw it as far away as you can!..
Also agreed!.. DON'T use the gears to slow the car... at best the box will be destroyed and depending on input rpm, the box can EXPLODE and seriously damage car and occupant.
A 26"/4.11/5000 combo is a proven 1.4** 60' combo... with 100-150 shot of gas I would come back to a 3.73 ratio if running 3spd, depending of what trap rpm you are seeing.. A bigger shot of giggle will probably require a converter designed for gas.
There is no absolute hard and fast rule as quite a few combos do work well with different setups..

[Oztrack Tuning]

I don't believe the 4.11s give any gains when the converter is big enough. I saw almost no difference between 3.9s and 3.07s with a 5000 stall. But you mostly need to make sure the car has enough legs in its 3rd gear to not max out.

[VT 2 EXEC LS1]

Ok,

you can all stop talking shit now...

1st question! Are any of you guys running a Turbo 400 in your vehicle?

Question 2! what trans slip? as said by someone else? when running a full manual turbo 400 there is no slip... its grab next gear and go, and convertor slip.. next to nothing under 1%

Question 3! When running a manualised turbo 400 you can pull it back a gear at nearly any speed, there is no engine braking as per you would get with a non manulised auto.

Question 4! why go turbo 400! because you will never have to touch it again apart from a service here and there! and NO SLIP!

Now to set things straight.....

I myself are running a WH Caprice 2 ton of car!, 6lt camshafted, Running Turbo 400 full manual, 4000rpm Convertor (No Need for any bigger!) Transbraked running standard style WH tailshaft (uni-joint each end), Running a 3.73 LSD rear end (standard IRS standard Rear end ie crossmember and arms etc), also running m/t street radial 235's

I have ran 200+ pases on it over the strip and no sign of any wear on any components, no slop in any driveshafts or uni's

Best bet mate, turbo 400 full manual with transbrake, 3.73 lsd rear end and a 4000rpm convertor and you will have a ball... just make sure you fit a decent shifter and trans cooler, also you will need a trans sheild over the top of the box.

any more gearing above 3.73 and it will run outta legs top end and be bouncing off the limiter

i was running 11.6's @ 121mph full weight with full exhaust and all (1900-2000) over the quarter with around 310rwkw

and never had a brakage, launched the car off the transbrake with foot flat to the floor

[ittwgn]

that should stir things up??:nutkick::lmao:

[Oztrack Tuning]

Good points made

Every converter has a variable amount of slip and most 4000rpm converters will have at least 4% slip at peak rpm. Thats the slip being referred to

What 60 footers have you run with the Turbo400? IRS wise on a good track the best that can be hoped for are mid1.4s consistently so people need to gear to be good enough for that and have the suspension/tyres to let it happen and then focus on being efficient after 60 feet.

My planned box is a Turbo400 with a Griner valve body the same as Craigs CAPA ute. The info i have is that a well built (non budget) turbo 400 can outperform the 4L60/65 at the strip and be incredibly reliable.

[saj]

that should stir things up??:nutkick::lmao:

He makes good points. Ive been doing it wrong, im gunna follow them and run some 11s.

[VT 2 EXEC LS1]

i responded to this guys post with our own personal car/usage,if you have not or are not running a similar setup as asked for how can you pass on justifiable info...
where do you get 4% slip from? is this what the yanks sell with their convertors?
obviously someone is telling crap!
if i had that much slip in a 4000 convertor id be taking it back and sticking it.
we use only local made(australian built)convertors and had no problems...
how many on here buy usa built convertors only to have them die/not stall right/to much slip,and have to send/return them....
each to there own,

You sir, are the one talking crap. The rest of your post isn't worth the effort to reply to as your obviously think your the only guy here who has experience drag racing and setting up cars.

Why don't you post what you know to help brad set up his car, stop trying to belittle other people, or crawl back into whatever hole you just crawled out of....

Why dont the transbrakes work?, I have had a t400 transbrake combo for about 2 years and i think if I can get it right it potentially can run some pretty decent 60fts and ets I have not done many passes as yet but i hav tried two different combos...

My biggest problem at the moment with my t/b is getting the car to hook up since i had my 4200 converter played with to bring up more revs my best 60ft is a 1.64 ant et was 10.80at 129mph with the car leaving line at 3400 I felt the car bogged down to much so I went and got the stall played with and now I am getting over 5000rpm off the line but heaps of wheel spin prob due to a combination of not having the car set up right and not good enough rubber my best 60ft was a 1.92 with an et of 11.3 at 133mph, but i have no excuses now I have a set of 28x9s and a set of koni adjustables 90/10s and some adjustable rear konis to test out

I am thinking of running them on hard for the rear and softish up front one of my problems with the car launching at 5000 was that the car would squat way too hard and bottom out then it would rebound just as hard and just unload the tires taking all the weight back off them hence wheel spin and more wheel spin
My car at the time was running a vortech t-trim with a blower cam on 12psi with a transbraked t400 with what we think is about a 4200 stall and 3.73 diff gears and at the time 356rwk, I am running a v7 on the same motor with a bit more power ..
I am hoping to test all this out within the next 3 or 4 weeks so I will let you guys no what comes of all this ...

[Oztrack Tuning]

If you can get a 4000rpm with no slip at the highest rpm of a gear, then that would be fantastic. But it is impossible. If you logged TCCSlip you will be lucky for it to be as low as 300rpm at 7000, i doubt thats even possible.

The transbrake wont load the rear suspension and create good preload of the suspension or the drive train which with a big converter will likely strip diff gears. With a 9" and anti-squat the transbrake would be fine. Unless there are monster tyres i dont think a transbrake will work with the IRS at going any faster than a 4L60/65 which we know can go 1.50 and below. We had a VY Wagon recently with a 4000 stall and 3.73s go 1.50 on 255/60 x 15 MT ET Radials and no front runner even.

[Oztrack Tuning]

This is a key question. What 60 footers have you run with the Turbo400?

Im hoping to see low1.4s on occasions and lots of sub1.5s soon from a Turbo 400 with transbrake BUT initially it wont be off the transbrake. Im not willing to risk the diff gears. The experience in the USA is that it wont be as fast anyway.

I must be doing something wrong... my 3.91 gears... the 6000rpm stall... the totally stock standard never touched 4L65E... the 1.5 second sixty footers on drag radials (in cam-only guise)... the fourty five 1.6 second sixties when it was bolt-on only... 165 passes (remember, stock untouched box) and 40,000kms of street driving...
11.7's @ 116mph... fairly quick times for such weak trap speeds... something isn't right! true fact... it'll go heaps quicker than that yet...

a smaller converter, taller diff gears, and only 3 forward gears with no overdrive would fix it right up...
it'd be a useless pig on the 48km country drive to the strip though singing it's head off at 3700rpm in "top" gear to do 110kph...


[QUOTE=saj;1770156]Why dont the transbrakes work?

1.64 sixty footers is not working...
if guys can run 1.4's and easy 1.5's off a simple foot-flat-flash off the line, whey the need for a trans brake to go slower?
it's well proven that the 60' mark is where races can be won and lost... you put a lot of pressure on the other guy by being a car length ahead after just 60 feet of racing!!!

steve you've got logs of my ute with the converter slipping what it does around 7000-7500rpm... i think you said it's around 300rpm at full noise...




converter slip at full revs is a fact of life... it's just what happens...
a torque converter, by nature of design, is a fluid coupling... there is (without a lock up clutch) zero mechanical connection between the engine and the input shaft... your connection is obtained with oil and the converter's various internal parts...
you WILL get a percentage of slip on even the tightest of tight converters...
even a stock converter will slip at full power and revs when unlocked...

[Oztrack Tuning]

It slipped a minimum of 392rpm just before the gearchanges (5.6%) Changing at just under 7000rpm its rpm came back to 5400rpm after the 2-3 change. It went straight to 4600rpm at launch - gives an idea how big the stall is. That was in a 11.725 pass.

The slip would decrease if the engine was revved further in the gear.

[Oztrack Tuning]

Just some more info Brett with the 1.50 60 footer and 10.8/125 in a VY Wagon (Procharged) slip is 500rpm at a 6700rpm change and shift extension to around 5500rpm with near 1000rpm of slip. The car would go around 4300rpm at launch. Thats a 4L65 with 3.73s

[pro 346]

Well when i had my gold ute with a t400 it went 11.80@116 with nitours tune less 6 degrees of timing, With na tune and 4l60e it went 11.66@116 with larger convertor and same diff gears, so i think my real world testing showed the turbo 400 was no slower which might surprise a few:eyes:

The problem with the transbrake is you cant control the rear end well enough. As you've found out you cant let the rear squat to hard or it just unloads on the rebound but you cant stiffen up the bump to much or it just shocks the tyre into wheel spin. I've tried about 5 different springs with different heights and spring rates and shocks from FE2 though to QA1 double adjustable drag shocks with 22 individual settings for bump and rebound and i still cant get a transbrake launch to come with in .07 of an off the foot pass in the 60".

This pass was off the transbrake with the 2 step set at 4500rpm. It just wheelspins from the start and carries the wheelspin until top gear and drives me out of the groove until i lift to get it to hook up. Thats the best 60" its done off the transbake, a 1.48.

jZBOK__PuuE

This pass is my best 60' at a 1.41. Its bringing up about 2000rpm just to load up the rear slightly.

I'm going Turbo 400 in my VE soon, Pete Ghele from Mopower has a lot of experience drag racing built many a 8 sec car. His big block is making 1000hp NA and it equipped with a transbrake equipped TH 350 yes a 350 not a 400, with 36 element sprag and aftermarket planetries and input shaft built by precise autos. A lot of ppl go 400s for there reliability hence why I am as I am spraying a 200 shot,

I have no experience with 350s only ever used glides or 400s, The 350 can be ordered with what ratios you like, and with the aftermarket bits available they are very strong much lighter and go right in with no tailshaft modifications from where a M6 once lived. Having said that being a daily driven car a 400 can be built using stock GM parts with some better bands and lighter drum and hold good power and last a long time. I would look seriously at the 350 if I wasn't spraying. Steve is right the 400 has great ratios out the box around 2.48 first 1.48 second correct me if I am wrong, Run a decent convertor and u can use a 3.45 diff with no issues, with no need to go lower.

Not having a go..but the road to 1.4's is not a well travelled one and if I were still relying on what converter versus ratios coming out of a gearbox off a Laptop program to get me down the 1/4 mile ...I'd still be stuck well and truly at 1.7's..but I'm not.

Hi Mark,

Here is a perfect example of someone who well and truly opens his mouth before having a think, Jez owns a 434rwkw ute with a glide I believe and is still getting setup? I own a VE M6 not sure how you got it mixed up, but anyway 1.4 sixty foot is pretty good for irs car but ordinary in the real world....You are a bit of an extrovert lol. A perfect example of how a thread turns to shit, And I am someone that has been drag racing far longer then most ppl here, I just dont open my mouth as in the real world 10s and 12x mph street cars were around in the early nineties,, 8s and 15x mph is now common, just remember that u arent god, just an extrovert lol. If you have to tell everyone how good you are you arent good enough IMO...Keep your comments to yourself and maybe ppl would respect you more, What you have achieved isnt to bad but considering a shop built the car and it cost u a fortune its not so impressive!

My bad :confused: so why was Jezas 434 RWKW Ute unable to match it with my self same 368rwkw.full weight Ute??? .
Fellow I'm pretty thick skinned, but it has not gone un noticed you cannot even throw a time slip into this argument, Per Say you may well have been drag racing longer than myself. Question ??? I have …RWKW for RWKW , weight to weight you have backed yourself into this argument ?, Now where are your LSx NA time slips ?? ?

.in fact, as you well know there are SFA LSX owners here who can front a 1.4 launch off a daily driver ,
And this is exactly what this thread is about imho...Just what is best for hard Core 60FT duties , Sould one plant a soul destroying 3 speed into the A4 or A6 or stick with what the good fold at Holden gave us ...FFS mate , Put up your own time slip along with a pic of the car in question and then you can Rip this Retiree.Pensioner into the ground, cause weight for weight / RWKW for RWKW You have not yet come with’in Farting distance of my 60 FT times..as for shop built cars :rofl:..keep it up....about the only goddam excuse you have left in the basket imho..

.
.Well thats my take..over to you :)

Just let me know when you want to run Head to head Willowbank in any Full weight Cam Only 5.7 LTR

[QUOTE=saj;1771470]The problem with the transbrake is you cant control the rear end well enough. As you've found out you cant let the rear squat to hard or it just unloads on the rebound but you cant stiffen up the bump to much or it just shocks the tyre into wheel spin. I've tried about 5 different springs with different heights and spring rates and shocks from FE2 though to QA1 double adjustable drag shocks with 22 individual settings for bump and rebound and i still cant get a transbrake launch to come with in .07 of an off the foot pass in the 60".

This pass was off the transbrake with the 2 step set at 4500rpm. It just wheelspins from the start and carries the wheelspin until top gear and drives me out of the groove until i lift to get it to hook up. Thats the best 60" its done off the transbake, a 1.48.

Thanks for the info much appreciated.. Its good to hear from people who have covered this as extensivly as yourself what you are saying is proven and makes a lot of sense. i reckon im going to have to go with trying to get the foot brake 60ft sorted as they were slower at the time than with the transbrake something in my combo isnt right, I have got new slicks and some koni adjustables 90/10s and a set of koni adjustables in the rear now and i have gone back to standard springs as well, but it will be very hard to compare my old 60fts as I have upped the power quite a bit so it should be interesting to see what happens .

sorry if its a bit off topic. has anyone run a 4000 -4500 converter and done some open highway km's. my nearest track is 300km's away and i plan on driving it there if i have to. i can handle swapping ratios when i get to darwin but not keen on swapping converters.
is there anything wrong with extended periods at under stall speeds?
if so, its it a matter keeping the fluid cool?
or would a lock uo converter solve any dramas.
sorry if its been asked before or if its off topic but the guy who started the thread has the same intentions as i do, so the answers in this thread are equallyas helpful to me.
thanks

What the hell does my ute have to do with this thread?

A. I have a Powerglide (the gearing is completely different to a 4L65E or T400 bar top gear)
B. I dont have a high stall I have a 3000rpm stall 10.5" Converter
C. Ive had about 3 runs the last time I was out in April and got kicked off the track just testing the setup out.
D. I had no setup at all, 3.46 diff gears, a towbar, etc.
E. The 1315Nm was with a MANUAL not an auto with a stall and torque multiplication
F. I was wheel spinning off the line

How about you leave me out of this

Someone needs to stop selling his own agenda and re-read the posts form the OP.


He asked about stalls and gears for a T400.
He stated he already has the T400, hence why he wants the info.
He obviously doesn't want to go down a different path.


How about we keep on topic.

Back on track, I'm running a T400, 3.89 gears, 3800 hi stall and blown LS2. Makes around 382rwkw's. Nothing special.... I will keep everyone updated as to its progress at the track, and will copy timesheets. It ran a dismall 1.55 60 foot, pedalling it with MT's. Its no "street car" anymore, as QLD transport wont approve the rear rollbars exiting the cab, so it has been deregistered - if it were a sedan she'd be driven to the track and raced in that way.

Will keep you posted.

Cheers

He makes good points. Ive been doing it wrong, im gunna follow them and run some 11s.

LOL! Me too saj!... And while i'm at it I might get a 2500 convertor and get back into the 11s too!

[darthvader]

hey fella, my R8 only ventures out to noonamah / berry springs, but the crate 4L56E and 4000 dominator stall (with lockup function) and 3.9's have excellent manners out on our highways....it cruises beautifully and would make it to kathrine easily (fuel cell may kill that a bit:rofl: ) I am running transmaxZ and a truck fluid cooler. The above mentioned set-up also handled repeated laps (till i got kicked out :jester:) of hidden valley powercruise floggin the guts out of it in the middle of the day (30sumthen deg) with no temp problems at all. nowadays i wonder how the poor old A4's managed to get a bad rep as even if my box blows up tommorow i have gotten my moneys worth out of it tenfold.

just my SAO............ (Slow Ass Opinion) :) hehe:rofl:
