I respectfully disagree the cam is the cause of that. I've personally run the GT-7 cam 208-220 121 LSA and it never fell off on the big end. I've seen those cams on Lingenfelter 427 packages make 750+RWHP. Cats clogged up? Maybe. See GolfinZ's closed thread where his cats were clogged up. His dyno sheet looks just like this one. Cats out made over 200 more rwhp.

Just because the compressor map reads one thing, doesn't mean the turbine side isn't getting choked to death. .49 housing is a very small housing and will build tons of back pressure, acting just like a clogged cat. Seen that plenty of times as well.

Very cool offering! Hard to decipher from the pics, but is there any ground clearance lost by running the pipes under and over to the fender?

Also, is a battery relocation required?

This is true, but I do not think this is the particular case since the exact same kit and parts on the LS3 @ 650 WHP (WAY more exhaust flow) is not displaying the same behavior up top.

I'm sure as the power goes up, user # goes up, accumulated total miles on this engineered product increases, etc........many changes will come, the turbo has already been shown as a future area for change.

its a t3 with a .63 ar. Its the back pressure. I have been looking at this kit for awhile on ebay and thats where it sounds like it belongs the builder sounds like a noob. Still need to get rid of the cats though.

That's more than possible. I do occasionally smell that rotton egg smell. However I know the stock cams power band looks just like this, peak power is at 5900, which is exactly where it is. But the cats may be exagerating the effect. The only reason they were left on was to make selling the car in the emmissions restrictive Denver environment easier. And to demonstrate that with this kit it is possible to use factory cats for those who have to.

They are .63 A/R, not .49.

SBC, I'm not a noob, I've been dealing with turbos for a LONG TIME! I'm not going to sit here and have a discussion with you about A/R, but .63A/R on a twin setup is more than plenty flow. I posted the graphs of cars with one turbo, more than able to flow 500hp worth of exhaust flow through a .63, there is then no reason that having twice the area to flow would suddenly restrict it. The fact that you don't see this, or suggest that (2x).63 is too small on a 550hp car in the first place says that maybe you need to look in the mirror with that noob comment.... (PS, I hate name calling, very immature, I respect and I'm damn knowledgeable in my field.)

A 208 on a 121 would peak much higher in RPM. Two degrees more on the LSA is 100rpm. Bigger splits extend the power out past the peak HP RPM.

If you think a 199 intake duration on a 115.5 LSA and a 208 on a 121 will have the same peak HP rpm, you clearly dont know cams. If you put the 199 on a 121 it would carry out 200 more RPM.

SpinMonster

Saying you disagree with a point of debate is one thing but insulting the guy and his product is another. I would think calling for cat removal or a cam swap would be a more mature way of approaching the discussion. I dont have the tech knowledge of turbos to comment on the finer points but I do know forum rules.

Pipedream

Gota ask... does this require any hammering, cutting, bending, etc, to the frame??? ( for clearance issues... )

VERY interested..

BLOWNBLUEZ06

Then how many more RPM would a stock LS6 cam allow for?

This many?

I think it's time to put your cam software down and try some real-world experience.

If you think that cam is the cause of such a horrible power curve graph, you clearly don't understand cams as they relate to F/I motors.
F/I can take a cam that totally quits at 5500RPM and push the power band far beyond that.

i say send me a kit and ill install it and see what happens. ill boost the heck out of it. see if it falls on its face or keeps going.

0CK@UPPCOS

No, there's a hole drilled/tapped in the frame where the turbo mounts to, but that's about it. On the under body side there is a small pitch weld that gets bent for clearance of the d/p.

I don't know why I don't have a better pic, but I'll get one for you. In the mean time this kinda shows.

We all know you that's the truth. If anyone will give any kit a good thrashing, it's you!

You're one of the only people I know that will race their own shadow!

Looks good. C5s need a cheap turbo kit option. Some people don't care about show-car quality welds, newest BB turbos or shiny parts. Just how fast it will go

golfinz

Just dont race it if the sun is behind you...you will never catch up

Corvette-Chris

*goes outside to test said theory*

corvette8189

Dont worry youll be the one chasing my shadow, the bigger the shadow the further im ahead.

Back on topic send me this kit and if it makes power across the board, Brett and Brian will pay for the kit

golfinz

Ill pay for it with the money yo momma gave me last night

0CK@UPPCOS

Let's find out!

I'll post dyno sheets tomorrow, and if need by Spin's got another cam for me to throw in there. I really don't want to go through all that trouble and effort, but if that's what it's going to take to prove the turbos DO flow.....

C5 kit yes, C6 kit no. C5 you loose about 1.25" (of the 6 stock) and that's comparing it to the frame (not the lowest point). C6 is tucked above the frame rail.

Both req a bat relocate, but everything needed is included (wire, connectors, etc) just no batter box or anything. But the small drycell batts fit nicely into the rear compartments.
