Drag racing launch and lowered springs

[VYClubby]

I have taken my Clubby to the drags recently and I have real trouble with traction. It wheelspins half track in 3rd! It has Superlow King Springs in it, but I am thinking of refitting my standard springs. I am thinking it will help my car squat more which will help it launch, as they are alot softer.

Below is a pic of my car at launch, it doesn't seem to squat as much as other pics I have seen. What do you guys think?

I ran a best E.T of 13.7 at 106MPH. My best MPH has been 109, so I think there should be a quicker E.T in it. It has made 248.8rwkw on the SAS dyno.

I would rather a quicker car than one that looks good low. I can fit the springs myself so it wont cost me a cent.

Mine is pretty damn low too and it affects the launch and it makes it wheelspin between shifts in the auto. I have logged it and you can tell it is bogging and popping up and losing traction between shifts. I was spinning with a 12.1 @ 118.6 with a 1.85 60' with 4.11s and stock stall. And spinning with 3.9s, 2500 stall and running 12.7s back to back with 30rwkw more than the 12.1. All with ET Radials. Light ass ute and light springs and stock shocks dont help at all.

Plus it can put big stress on the drive shafts as I found out when i broke one. Ill change it back up again one day or just put some airbags in the back.

Fe2 rear 90/10's up front and MT/streets.

Or do what I did keep the low look just run MT/streets on persuit rims and straight away after only two passes 12.1 with 1.7 60' with heaps more left.

I can't run pursuit rims as 15's wont fit over my brakes.

How are 90/10's? Do they handle O.K on the street? I want a decent all round package.

[RB30X]

I would just get some M/T ET's on whatever the smallest rims are that will fit. Mine are on 16" rims and a mate has some on 17's. Drop the tyre pressure in these to 14psi and you won't have any tractions issues at all after a decent skid.

I'd only go the 90/10's if you had a ute with no weight on the rear or if you had an extra 40-50kws and needed more weight distribution.

[Mungrel]

I took my ute down the strip with SL springs all round (and a lot of extra weight in the back) i found it to rebound off the bumpstops on a few occasions.

My next attack, i'm thinking bout putting FE2 springs in the rear and seeing how she goes. (as well as losing the extra weight lol)

[VYClubby]

Is standard HSV pretty much FE2?

[Hellbent]

cam only......sl kings all round. 90/10's up front, 235/60/15 et street's
1.53 60ft.

you can make the springs work......with the right combo

Agree with hellbent as there are plenty of similar cars with basic setups in the 1.5,s etc.. good luck/nice car:)

[JezzaB]

...How are 90/10's? Do they handle O.K on the street?...

So how are the 90/10s on the street? Handle like a slot car? Dont pop up the front all the time?

[OLS108]

just as important as your springs is your tyres ? what are they ?

[Hellbent]

Jez

90/10's are ok on the street.....you do get a bit of float if you come across something like a hump in the road.......bridge crossings are a good example, where the road has slumped just before the bridge and you get a sudden rise just before hitting the bridge.

They corner no probs.
And while they have plenty of rebound they have bugger all compression so they can seem pretty firm on a rough surface.

Feels good when the ass sinks and the nose lifts at WOT.:)

[markone2]

Cam only 1.480 sixty Ft....H/C 1.469 sixty FT. 90/10's up front, 235/60/15 et street's . 22psi exactly.

Rear Shocks....DON"T f$@#%k with what the good folk at Holden provided....for 330rwkw cars and under you won't improve on factory.....imho

[VYClubby]

My tyres are Hankook Ventus Sport 104's they are 245/35/19's.

^^^Markone2 is that the same for the springs?

Well I guess I will be refitting my stock springs. How much time would you think I'd gain refitting the stock ones?

Since this is about drag racing launches, what was your 60'? i would also get a set of M/T ET's radials before changing much else.

I've managed a 1.61 60' with an M6 running lowered eibach springs using M/T's

[RED R8]

With street tyres I would say bugger all ,your tyres would be you downfall.Set up some cheap 17" rims with MT/streets and your times will plumet.

Whats your best 60' with your curent set up ?

What mods do you have ?

My best is 2.138

I have a Mafless tune and OTR, and have removed the rear resi off my 2.5inch exhaust. It has made 248.8rwkw

I guess my final question would be is there going to be enough benefit in my 1/4 time to offset having the car no longer lowered??:confused:

Just swap the springs for the drag days... it's only a 15 minute job to change them over. :)

Yeah the 60' and ET is worth a big congrates, pity your car drives like a POS. Drag and street dont mix mate. Everyone knows what yours is like, dont play the "its a daily sweet driver games" :rolleyes: You wanna have a dig at the GenPD now? Its gone mate and it made some ****ing good MPH. Lets play with the new turbos....

Ahhh you guys know me too well. Too many beers and is the "Jez's War on Everything" lol

Still I ment what I said :stick: Still drives like a POS

[Oztrack Tuning]

I have heard that Tein's are good and might just give the best of both worlds?

I think the biggest difference to a M6 will come from 90/10s and slicks at the rear or at least some 17" drag radials to clear the big clubby brakes.

The problem with a M6 at the drags is breaking things and also a mandatory textralia install. A4s with stalls do it much easier - my rear axles are 130 11s passes old.

[markone2]

I surprised your so intimately acquainted with the pros and cons on how the POS SV8 drives :confused:......perhaps someone handed you the keys while I been away on one of my overseas jaunts, can't think of any other explanation that comes to hand immediately other than keyboard asumptions...perhaps a discreet inquiry to those selected few who have actually driven the car might be enlightening , certainly enlightened a few on recent trip to Noosaville where the car carried 5 adults and accompanying luugage....but then I do concede keyboards , preconceived notions ,and a belly full of piss makes for an LS1 authority these days..

Pretty much the exact same authority that could until recently be heard telling all in sundry the car had worked heads when running consistent 11.00's cam only . backfired a beauty on the story tellers that little pork pie.

But for the sake of argument, why not humour me and inform us in your own words , based on your own FI experince just how a 10.765 quarter mile LS1 should behave on road ....in the exact same format it races on the track.

[Martin_D]

Good to see you drive it on the road a bit M12
Would have been cool as seeing that big girl cruising on the open highway with another 500kg in it, 4.11s singing, 6000rpm converter minus lockup slipping away at 110km/h, exhaust cutouts blaring, MTs wandering, windows down. True muscle car stuff, and something to be appreciated that you use this thing in this all too sterile and sanitised world. Nice work! :)

Takes me back to the day when the local drag chocs that owned a servo up the road almost knighted us for being able to drive a 12 second car 80km to 'Victor' and back. Unheard of in the day when men were real man, all cars had V8s and you could smell them both coming before they got into eyeshot :cool:

Exciting stuff from a bygone era ST.....but in reality......
no slip at 110kph @ 2500rpm...all good :).....exhuasts cutouts were given up as loss over 2 years ago when running 12's .,your memory is truly outstanding ST..but just so your fully up too speed, the car runs a FULL twin 3" complete with cats / twin mufflers and very large rear reso .
MT's wondering :confused:...not with correct set up...I think you know this one..ensures consistent 1.4 sixty footers...I'll admit many attempt to emulate by bolting on more and more HP..alass very few succeed .
Weight 1640..a road we have traveled before ....but I didn't really have to spell out all the above for you..did I :D

[Mungrel]

Whilst we're on the topic of lowered springs and drag launches.

Would there be any benefit to putting FE2 springs in the rear and leaving the front lowered, or would that be a waste of time and make it look ridiculous?
This will be on drag slicks and front runners.

Also, whats a pair of 90/10s worth these days?
I've currently got 2 strut setups at home.
1 (in the ute now) AGX adjustables with SSL springs.
1 (in the shed) FE2 struts and springs.

I wouldn't mind putting the FE2 springs onto a set of 90/10 struts for drag meets

^^^ That was going to be my next question too. Would it help? Then I can just swap my rear springs at the drags.

Nope not at all mate. Good hearing it though, shuts a lot of people up :cool:

O.k if you ladies have stopped having your girly fight:limpy: Can you get back to helping me out:)

Would fitting my stock springs in the rear only help? That way I can just fit them at the track.

[Vulture]

I have heard that Tein's are good and might just give the best of both worlds?

I was surprised at how well the Teins worked on my VZ at the recent private drag day at WB. They managed a low 1.6 60' so I don't think it would be too much of a stretch to suppose that they could do a 1.5 with a bit of experimentation. They were set at about halfway damped front and rear at the time. Slightly lower than FE2 height (not much). If you want adjustable suspension or some improved handling over FE2 then this seems to be a good option but as M12 says, stock FE2 is hard to beat for drag duties if that is your top priority.

yes Dr. i concur, the I was Very impressed with the TEIN's fitted to your VZ, if i were to upgrade i wouldnt be going for anything else.

When I ran superlows and 19" rims I did a best of 1.9 60" for a 12.9 @107mph (tune only) but the big factor for you will be getting more grip rather than changing springs I don't think going to the effort of putting in stock springs will give you much gain but setting up some MT/Streets will let you launch ALOT harder and times should tumble or if you are really keen do both.
My goal is to run a 11xx pass cam only without changing suspension I like my car superlow so I run it superlow the big change I have had in my times with the cam is getting a Tex and MT/streets and launching with some decent RPM's.

:confused: Dunno, never seen it tried, I'm guessing you'd want the front heading skywards as the rear comes down ( to a limit ) for max traction from the DR's

90/100's aprox 1K and upwards ex pedders....aprox $200 to have re-valved rrp..no contest imho :)

[VYClubby]

Can I run MT streets 16's on the rear and still have my 19's on the front? Aren't the MT's different ply to my street tyres? The guy at my tyre shop says I have to use front runners too. Is that right?

MT/Street radials can be driven on the street they can also be used with the 19's up front so you can put on the MT's at home leave the 19's up front and drive it to the track or drive it to the track with the MT's in the boot with a trolley jack and swap them at the track....easy...just make sure you get Streets not slicks.

I've been out once and had all sorts of problems with traction. Is your car M6? I only managed 13.5 @ 108 (street tyres 35 psi, rooted clutch 41 degrees!) . Its definitely harder than it looks! FE2 is the way to go and 90/10s up front, plus ET streets of course. With that power figure its only a matter of time before you get a 12, it comes down to set up and practice. Good luck with it

[RED R8]

I did find my 19" tyres heaps better let down to around 22psi It was the key to a 12.9 with 218rwkws but traction is a big factor in good times.

[VYClubby]

Yeah I let my tyres down to 20psi. Even when I was taking off with slipping the clutch at a measily 2000rpm, as I fed on the power it would spin, same through second, then in 3rd they were just spinning enough to squeel. It made for a few full throttle fishtails trying to find a good launch which was fun!:) My mate took a video and you can hear it squeeling all the way up the track. I still beat an F6 Typhoon though!

I know the feeling my street tyres were very average then when i tried the 235/60/15" Mt streets which look quite small I could not even with 390rwhp spin them ,my first launch was at about 4000rpm and the G-forces actually pulled my hand off the gear knob off the line and I struggled to get my hand back on to slam second.

I might have to give it a go then one day

Getting my FE2 struts re-valved sounds like a better idea ;)

[vhr32]

Who revalves standard struts these days?

I rang Pedders tech dept and they dont do any 90/10s anymore because their own factory rebuild centre has closed.

I thought to get 90/10s it was either revalved Konis or Bilsteins?

I have my VT-VY Koni 90/10s currently for sale but I think i'll get some std struts done next year.

[VYClubby]

I refitted my stock springs on the weekend. So I'll be at WSID this Wednesday night too see how I go. It definately squats a heap more than with the stiff King Springs, hopefully this helps it off the line.

[TAKEITEZ]

good luck mate and be sure to let us know how you go!


i also set my fastest times with standard HSV issue rear springs... but the camber kit also helped...

on the street having run standards, king SL's and king SSSL's in the rear i can say that the standards are better on the street than either of the kings even with the camber kit adjusted to suit each spring set... the SL's get a little tramp, and the SSSL's shake the car to bits its that bad... but the stockers are the best so far...
on the strip they out shine all the others too... no tramp into 2nd gear when it squirts the tyres on that shift... beautiful...

just looks gay :(

[VYClubby]

Yeah it doesn't look as good now, but if it is quicker it is well worth it. I noticed your in Launceston. I was born there and my family still live in Prospect and my sister is in Golden Valley. Where abouts are you? I'll keep an eye out for your car when I'm down next.

And :idea: if your in the market for some prime real estate in Launcestion ( 3 bedroom house ) now zoned commercial in Kings Meadows...pm me...its been put on the market *To Sell*.asap....and priced accordingly...got an engine too pay for :confused:

[TAKEITEZ]

yeah mate, launceston is me... actually in riverside a few kms up the river...
LOVE IT!!!!!!... moved to perth (WA) for a while but ended up moving back to tas shortly after... currently drive a silver VY II Maloo ute with 19" koya's and a pretty loud exhaust...

good luck selling the house mark... there's a fair bit for sale round here... but real bargains aren't that common... so if its the right place and you find the right person you'll have no drama's!

VYHSV dude let us all know how ya go when you do get back to the strip...
i'm interested to see results

[VYClubby]

^^^ There wouldn't be too many Maloo's in Launceston. Yours must get a ton of looks cruising around! I am going to the drags tonight so I'll let you know how I go.

Thanks for all your advice guys tonight I ran a PB of 13.301 at 179.29kmh! That was in full street trim including my 19's so the stock springs did the job! I can smell a 12 second pass!
