TT BD

Question: Need some help selecting a Cam for my 99 Z28/6 speed...Putting a set of T-44 Turbos on it...Any suggestions?

Thanks

Call CompCams. I think they'll recc a reverse split, like a 220/216 or a 224/220 on a 114.

Ignore them if they recc a 112 LSA. Their duration recc's are ok to go with.

FWIW, here is what LPE uses:
205/212 5xx/5xx 116 LSA Twin Turbo

Very similar to the '01 LS6 Cam!
204/211 .525/.525 116 LSA

Supposedly you can find the '01 Z06 Cam for $175.
But DON'T use the '02 Z06 Cam.

This might be the correct '01 Z06 Cam part number, or might not:
12560950

:cool::cool::cool::cool: I hope you get a fast car with those TT's ...

This subject has been hashed out on several forums. There are many different opinions on which way to go and just as many saying to go another way. Fact of the matter is, until we get some real head to head cam comparisons it is a crap shoot to find out what works well with a turbo setup. Sad thing is, since the first affordable turbo is just hitting the market, there is not much testing going on. It will probably be at least a year before we know what type of cam a turbo LS1 works best with.

Good luck.

I think LPE has proven their cam.
;)

Some will say a Cam doesn't make too much diff on a turbo.
I don't think you can go very wrong as long as you do a 114-116 LSA.

Go with LPE :yesnod:

Harlan runs a 112 cam and is dynoing mid to hi 600rwhp. That was suggested to him by Dave Inall before incon fell off the planet. Not saying its the way to go...just that you dont really have a definitive answer when it comes to lsa choice. i have the 01 zo6 cam...advanced 6 degrees!!!!
573/676 dynojet on a worn out turbo...worn out to the point the turbine wheel was rubbing against its back plate tho i doubt it was that bad a month ago when i dynod

MelloYellow

114 would be a safe bet.

Can you confirm the p/n for the '01 Z06 Cam?
I don't think we want to get the '02 Z06 cam.
Plz tell me they haven't change both part #'s and cams to the '02!!

My friend installed LPE Heads, cam, and a ATI procharger in his car. LPE shipped this cam: 204/224 Duration .554/.567 Lift 117 LSA
It dynoed 586 rwhp at MMS :eek: It purrs like a cat, no lope at idle what so ever.

But after 1 week later, he bought an even bigger blower and a bigger cam. We don't know how much HP it makes yet. We have yet to put it on dyno...
By the way, that cam is for sale for $200. One week old...

Mello,

I respectfully disagree with LPE proving their cam. They haven't put out any numbers that show their cam selection is best. Their cam puts out 550 bhp with twin turbos and ported heads. Cerra's kit is putting out right around those numbers or more with a completely stock LS1 single. They get more hp for their 650TT package by upping the boost and forging the bottom end.

I fully disagree with the statement that a cam doesn't make too much difference with a turbo. Perhaps with a built iron SBC it wouldn't however with our aluminum LS1 which has boost sensitive heads, I think a proper cam selection would produce more hp and keep cylinder pressures down to where lifting heads would not be as big of an issue. I am really impressed with the MMS H/C ATI package. 63x RWHP on a stock bottom end LS1 with only heads/cam!!! :eek:

Also there are the theoriticians saying under 114 LSA is bad for FI because you get too much blow through. These are probably the same people who were saying that a 112 LSA on an LS1 wouldn't even idle a few years ago. Now people are down to like 108 in some cases. All I am saying is that eventually someone will do enough testing to show that a reverse split or intake biased or exhaust biased on a turbo will give more HP on whatever setup than some other cam. Right now we just don't have enough cars or turbo LS1's out there to say what works best on an LS1. I think it will be at least a year before we have any real accurate comparisons. I would love to see a Cerra setup on a LGM G5 H/C package using the truck heads. I am still hoping LGM becomes one of Cerras authorized installers. :cheers:

There are a lot of opinions out there on Turbo cams and how to pick one. I'm just commenting on the general consensus.

If I was picking a turbo cam, I'd go 224/220 .568/.560 114.

Since I have a similar cam, if I go Turbo, I won't swap out. I'll use what I have and I expect it will perform better than stock for sure. I should be testing a 216/224 .558/.558 114 with a single turbo as long as Cerra doesn't change the price above $6995. ETA 2.5 months.

I made 610RWHP with my twin turbo LS1. 221/222 560/560 114 if I recall.

Godspeed, who makes that cam you mentioned? Is it a standard grind? That is just what I am looking for.

Godspeed

ARE had the custom grind done for me.

Nice #'s.
I've flip flopped back to a SC setup.
Gonna do the Vortech V2 SQ.
My money is coming in, so no more waiting finally.
