I bet your numbers are higher NA but youre also manual and with a fast 92 . How is that 10 bolt holding?

Yeah but our builds are close enough. 10 bolt is still alive knock on wood, but i baby it basically. No super hard launches and stay away from any wheel hop. I know it's just a matter of time though lol

Change the cam, get a fast 102-102 TB and a 102mm maf or go speed density And you'll make your numbers . Never seen that cam make good power . And the ls6 intake is killing you.

Something is not right, i made 401 hp with 241 heads, Ls6 intake 1 7/8 headers, stock tb and TSP 228r.cam. and my stock injectors were at 98% duty cycle.

No way your inj are maxed. Youve got a fuel issue.
You cant run a 450pump on sfock wiring and expect 450. even an older hotwire kit wont make it put out alot. and youre likely overpowering your regulator. also if the charging system isnt up to the task it will cost you also.
I bet he is trying to command a very very rich wot afr and has added a ton of fuel because the fuel pressure or volume is so low it cant keep up.

Check there first. fuel and voltage.

Go from there.

That cam is insanely large for the displacement, their Stage II would have been plenty. If money is an issue I'd go with a Dorman LS2 intake and a Warr 92mm throttle body.

Youd be surprised how many "i want the biggest cam and most horsepowders the internet says i need" requests i get on the daily.
Alot of them are for 5.3s also because the internet told them a 5.3 is the same as a 5.7 only cheaper.

Putting a literal max effort donkey dick cam in something isnt going to give you what you imagine unless you are willing to go all the way with it, and that doesnt mean just cncing a set of stock heads.

If this is true, your running way rich killing your power. Something doesn't sound right to me.

Yeah dropping anywhere from 2 to 3 grand in one shot isn't so easy lol. You definitely doing the 9 over the 12 bolt or S60?

Isnt a 102/102 combo too big for a stock cubic inches car? Not trying to sound stupid or sarcastic, I really want to know. Cause there are too many threads here stating that it is too big and other stating that is not gonna be a problem. Now yesterday I read a thread where Tony Mamo states tha a 102/102 combo is not too big for a stock cubic inch engine. Again not trying to be stupid or sarcastic.
When I bought the cam I used the contact form from the Brian Tooley website asking for which cam will be better for my set up and thats the cam they recommended. I also contact Texas Speed and they recommend me to Magic Stick 4 which is another huge cam. Would Texas Speed have been better? Well maybe if I had chosen the one from tsp I would have been better because they could have made me a package, but I could also have had the same problem.

Thanks, I'll look into that before changing anything first.
