cam size for ls3 ?

[ATOMIC MALOO R8]

what is the biggest comp cam grind you would go for A6 LS3 with stock converter
with LOW to MID rang power requirement not interested in top end ones
did a search but after 20 pages mostly on lsi :confused:

[LJCHSV]

you sure you wanna go that route?? It was the worst thing i've done to any of my cars.

Check with Steve OZTRACK he just did my VZ 6.0 ltr M6 its fantastic down low 800 - 7000 rpm. Doesn't drop off after 5000rpm 263rwkw all down LOW.

please elaborate

[LJCHSV]

please elaborate

Please dont get me wrong...as im not trying to be a smart arse at all...Just trying to say..that you have a beautiful well refined ute, such as you do....(not sure if you drive it everyday or not)...but just from my past experieinces playing with cams, my VZ Maloo , which i had cammed..was the worse thing i could've done..the thing drove like an absoloute pig..and spoiled what was a great car.

Sure it sounded tough, but when you drive it everyday...it does get a little old!!!....In my opinion.

I'm not sure if there's alot more to installing a cam then 'JUST PUTTING ONE IN'... but if it was something i was going to do in the future...i would be doing alot of research as too what else goes with it to complete the package.

Having experienced the 3 most known ways for power (blower, turbo or cam)
i think the 1st two are they way to go...IMO

Drove like a pig elaborate WHAT SIZE CAM !!!
Mines a beauty !!!!!

WAS your vz maloo M6 or A4 ? i would never put a big cam in a Manuel street car again either as i have done this a few times when i was younger and turned them in to cars that were very tiresome to drive full time great for a cruise and then put it away again
but in an auto it is a different kettle of fish i have found
i have been driving a 355 stroker with large cam (to big really for a 4x4 hilux) with T700 auto and 3000 stall for 8 years every day and it is as docile or as wild as you like what ever your mood takes at the time sounds like a beast and drives like a Pusey if you wont
kick it in the guts and it will tear your eyes out :)
but i do agree with what you say to big a cam and no stall would be shit house as well
i only want to go low to mid range with stock converter so it wont be very big probably wont even hear it at an idle going 2300 harrop blower after Xmas so this is just part of the work in progress but i do want to keep the nice manners the car has now but with a bit more stick :)

cheers

[EXCESSV]

size of cam and the person that tunes it will do ALOT to the drivability of a car!


to the original poster...
a cam for low to mid range power something like a 22X/22X @ 112 or maybe a 22X/23X @ 112 could be the go

i run a 224/228 @ 112 LSA on my 6L L98.
considering u have same heads as the L98 but with extra .2L it should be a great cam.

my biggest want was for good low to mid range power and thats what i got.
driveability on a manual is great and has the slightest rock inside the car that its not wild or attention seeking.

He is thinking of a blower remember so perhaps something with a wider LSA would be better, 113+LSA? The L98 has been responding very well to these 220ish cams so I would imagine that the LS3 will be similar - should make great torque!

Yep Dean, you need the glasses. There goes ya tax return :)

Yes you should.

bit slow

[EXCESSV]

Yep Dean, you need the glasses. There goes ya tax return :)glasses were on tim...maybe i need stronger ones :lol:

in that case yes Vulture is correct a LSA of 114 is preferred if ur gonna go blower...but my comments still stand on a nice 22X/22X comp cam :D

[BlownLS7]

Hi AM.
you will not be dissapointed with a 224/228 @ 114 ,this will be nice once the blower is added.easy to tune for smooth idle.and makes great all round power.(feel free if ever in brisbane to have a look at mine with H122).and the power starts early.
i also saw whiteknights crewman and with smallish cam,is sounds and goes great so there are options,
cheers paul

don't worry about the glasses mate need mine all the time :)
so if the LSA WAS 114 INSTEAD OF 112 with the same grind WOULD the performance be the same only the 114 would idle smoother and be better suited to the harrop 2300 ?
so how big a grind can you go before it starts to get out of low to mid range with the extra few cubes of the LS3 ?

[EXCESSV]

cant say if the performance would be the same...but being better suited for the blower than the 112 LSA cams then thats when it would make up for it my ALOT!

but it WILL idle smoother and WILL be better suited for a blower.

this is mine with the SQP custom grind comp cams 224/228 @ 112
(pretty sure bowlerr's cam is a SQP custom one too...or one that SQP recommended for him with the blower.)

not by any means a massive figure compared to the GMM one but the power and torque come in low and stay strong

its not until 2400rpm that the power meets the power of maffless and bolt ons...so any bigger cam and it wouldnt meet bolt ons power level till later which isnt what u want...
power stays strong till about 6200rpm then falls off a little which is mainly to do with my rear exhaust section being a little restrictive with it being dual 2.5" as opposed to my front section being dual 3"
will b sorting that out soon tho :D

torque is strong from down low and peak torque arrives at 4300rpmish and keeps going
450Nm of torque from 2500rpm isnt too bad :lol:

[HYMEY]

114 for the blower, go with bowlers cam, Its a very ggod grind L92 heads respond well to 114LSA, they dont like overlap.

sounds good what does it idle at ?
and what is the little spike at about 1800 on the torque curve

Im not sure what you mean by "whats the biggest you can go before its gets out of low-mid range"
Anything bigger than the factory camshaft will loose out on low end tq and power.
At the end of the day everything is a compromise. Having a nice cmashaft that will make good bottom end figures may suffer when you strap the blower on. I think your going to have to decide what you would be happy with. Something a little softer down low till the blower goes on or stick with NA and get a custom ground camshaft that will make good low end tq /power.
NA stuff with teh l92 heads seems to favour a larger split due to the intake valves increase in size.
After looking at some dyno sim stuff (all NA), between 8-10 degrees split with XER lobes, 580 lift and a 114 LSA looks very favourable for those not needing the highest peak kw but want a very strong everyday car.

thanks

looks like a hard call

[macca33]

There's nothing really difficult about it. The same cams that work well in LS1-LS2-L76-L98, will still give good results in an LS3, I'd imagine. The trick is to keep the durations below/at about 224, lobe separation at 113-115 for stock converter friendliness and the lift at .580+ - if you want the strong torque in the low-midrange. Such cams will still provide good power to 6500rpm too.

Why not give Sonny or Oztrack a ring for a recommendation - they have plenty of runs on the board here.

Cheers,

Macca

[SS Enforcer]

224 228 581 588 114 +2 that cam will give you very good power whilst not giving up much at all down low.

My car goes very well with that cam in it .

cheers

[EXCESSV]

sounds good what does it idle at ?
and what is the little spike at about 1800 on the torque curveidles at 750rpm ish...will get ya exact when i go for lunch soon...

the spike might just be Delco getting the car up into the gears or something not sure mate.

[ATOMIC MALOO R8]

do all L98 heads have differant length valves or only LS3 ?

see hear http://corvetteactioncenter.com/specs/c6/2008/ls3_page6.html

[SS Enforcer]

Hmm thats different .... I don't think the L98 has differing Valve lengths.

cheers

i run a 224/228 @ 112 LSA on my 6L L98.
considering u have same heads as the L98 but with extra .2L it should be a great cam.


Sorry, slightly OT but how would that same sized cam go in an LS2?



my biggest want was for good low to mid range power and thats what i got.
driveability on a manual is great and has the slightest rock inside the car that its not wild or attention seeking.


Exactly the same as what I want as well as that sweet idle rumble...

[EXCESSV]

Exactly the same as what I want as well as that sweet idle rumble...ask Delco or HOWQUICK via pm or give them a call as its their custom cam and they can tell u exactly how it would be in a LS2 etc.

[Vulture]

Remember also, LS3 has a tad more compression than L98. Would this change recomendations?
