Cam specs and results
Hey guys,
Time for me to get busy with my clubby.
Just wondering if people with LS2 6L's could post there cam specs + mods and there power at the rear wheels.
I have been reading a bigger cam suits the ls2's perfectly however can't find the thread that i read with the specs
My mods to go on are -
Xforce headers + Hiflow cats
KTMR OTR
Cam
Dual valve springs + retainers/bases/seals
Moly pushrods
25% underdrive kit
I'm yet to decide on the grind of the cam but i am thinking something around 232/238 113° - need some help deciding really
Chasing 320rwkw
Also do the vz ls2 6L's run a single bolt or 3 bolt cam?
Thanks everyone!
320rwkw should be achievable in an ls2, i know chevs performance recently put a comp 231/239 113 lsa cam with decent lift in a ve ss, maybe give them a call and see how it went, i think that guy did his heads as well, there in Melbourne. I'm interested myself to see how that cam went as well, haha.
either way will be a good set up.
this is the comp cam link for that cam http://www.compcams.com/Company/CC/c...csid=1403&sb=0
Turbo L98 FTW
I have a 218/233 in my 6L - Made 325RWKW
thanks guys, yeah there roughly the specs im looking at cpbait, i pretty much want the biggest cam i can get without touching the heads ;p
oh nice, yeh these cams are cheap too from the states atm and could get a package deal from say comp too with cam, valve springs to suit and pushrods, might need fly cutting of the pistons with that cam, but might be ok in a ls2, have you been on to ls1tech and i think ls2.com is another one, American forums but gives you a good idea of what there running and then can compare to what were running here and get more of an idea too.
yeah mate thats what i've been looking at, cheap comp cam packages atm! Been to my mechanic today and his gonna find out whats the biggest i can fit.. The ls2 forum i went onto in the states was really helpful and gave me the specs i wanted but i just cant find it anymore haha. Cheers for the help mate
haha always the way, yeh the American forums are pritty helpfull, all good, good luck with the build.
cheers mate, had a good look on ls2forums.com and high 220's low to mid 230's are the best with around 112-113 of lift. Vz ls2 is a 3bolt camshaft so can get a cheap kit from the states
Went and seen pete at CSV today.. booked in there for august, headers/cats/cam/springs/retainers/otr/tune.. We decided on 232/234 112
the old 232/234 you'll get your 320kw or very close to it im assuming its a manual
yeah mate manual ofcourse, pete at csv thinks be 310 on his dyno as his has always read lower and true he thinks.. he said to expect a few more on anyone elses tho so have to wait and see how it goes

My mates car ( 111oud) made 445.8 with a stock clutch and it was slipping. It's the 232 234 with Joel prince tuning it.

I'm going to assume you mean 445.8rwhp.Originally Posted by eaton v8
I've got a similar size cam, heads, OTR, tune and got 335rwkw or 449.2rwhp.
my little sleeper
That's a good number and yea your right so that's two cars with the same cam so now he has a good ballpark as to what he can expect. Hairy had stock heads.

He also found with this cam he made better numbers with twin 2 1/2 than the twin 3 inch

Nice car too jesterarts.

Yeah, I've got the x-force system which has the massive restriction @ their badly engineered merge point. Hoping to get a manta system on her down the track and should find a few more kw.
Cheers mate.
my little sleeper
Funny you say that they were both xforce systems.

I'd say with the xforce that merge would be the cause of this sort of situation...
After the merge in the 3" system there would be more turbulence and the scavanger affect would have been severly compromised.
I think HP-F did a test running a decent twin 3" against a decent twin 2.5" and they essentially showed no performance change.
Though interesting to keep in mind. When buying xforce, go for the twin 2.5" for better performance.
my little sleeper
But to contradict my self I got massive gains when I changed from a custom 2 1/2 to the 3s but I did change from try ys to 4into 1 soooooo my thoughts are the a lot depends on the car and condition of the engine as to the end result. Well i ran 11.4 at 119 so the twin 3 inch x force so it carnt be that bad. Just my thoughts but in the end don't go any smaller than 1 3/4 long pipes if you want to extract the best from any cam swap. I think we may have hijacked this thred slightly but every thing counts with These engines as they are so sensitive in the hunt for power.

I have a VE Clubbie with an LS2 and manual. It has a Comp Cam 232/234 with X-force 1 3/4 extractors, 100 cell cats and twin 3 inch x-force system with the rear mufflers removed and hotdogs installed. I also have a VCM OTR and Mafless tune and it put out 315RWkW with the factory clutch slipping at the very high rev's.
Personally I would go a twin 3inch system because I prefer the sound they put out, but I cant stand the muffled noise the x-force rolled tips makes hence why i removed them put straight cut tips on. I also agree with "Eaton V8" and dont go anything smaller than 1 3/4 extractors.
^^ Your mods sound about right with your pwoer figure, nice mate!
Thanks for all the info guys, is helping nicely.
Once my cam is in my mod list will look like this
- 1 7/8 Headers
- 100 cell Hiflow cats
- 2.5" dual custom exhaust with only a hotdog on each pipe (its loud but no drone)
- Comp Cams 232/234 112 camshaft
- Comp Cams 918 Beehive valve springs
- Comp Cams Retainers
- CSV OTR
- Tune
Ohh and is manual, gearbox got rebuilt 2000k's ago and hd clutch was fitted
Most of you should know Pete Dichiera aka CSV who has built holdens for production to which are compared to HSV.
He is doing my work and has told me the following.. LS2 with a cam etc, being a cathedral port head you will not see over 315rwkw read on a true dyno (said to expect upto 330rwkw on various other dyno's), the heads don't flow enough. If you want over you will need the heads done. You can help the flow by fitting bigger headers, 1-7/8 is the only thing he recommends when putting a cam in without taking the heads off and a 2.5" exhaust is what he likes to work with. On a standard head 232/234 112 with between .570 - .600 of lift is perfect however excessive engine braking will stuff a valve but normal driving and giving a bootful all day will be fine, says anything over .600 of lift is going to f**k a valve when you decide to do some spirited driving.
Thats just relying on the information he has given me, and i do trust what he says as he has done plenty of testing on these engines..
Once i get the work done (just under 2 months) i am taking it to another dyno to see the difference in results
But for the quality of work CSV is the cheapest i've come across, pete is really looking after me
Hi HSV453,
The information that Pete told you about stuffing the valves is the same information I got from Power Torque Engines when I got mine done. They said anything larger than a 232/234 you will have problems. I assume you will be going a Maf-less tune too.
Let us know the figures it puts out once it is done.
Paul
Hey mate,
Good to see some solid information between two different tuners!
Yes maffless/custom tune after the cam has been fitted, will be sure to post up some numbers after she is done, 1 and a half months wait is going to kill me
Hey fellow rev nuts ..I luved the read
I'm doing.some work on my 2005 gto coupe have already made it breath better with Cai tho should of went the otr as I'm now doing the cam up grade to the comp 232/234 plus mafless tune so hoping for some good results
Yes also has gene headers 3" pipes ,sterling hi flo cats also did the suspension lowered by 30mm
