Well i think his clutch is slipping. He only put down 412whp and 367trq. It has to be slipping because it has slipped in the past when its was stock the stock clutch has 97,000 miles on it and cant hold that much power!

LOL my cam only TSP 231/237 cam did 413/380 his clutch has to be slipping.

 

Or a bad tune.......

 

just got a dyno tune from MC racing.

 

I'd be pissed if those were my #'s...

 

Stock 2000 clutch with almost 100k is my bet.

 

yeah because i have seen 400-430 with just the ms3 cam

 

only one way to find out

 

yup he need to get a clutch

 

put a clutch in and redyno

 

So, is he gonna put in a new clutch?

 

Do it!

 

I bet its his clutch.

 

yes he is going to save up for a clutch.

 

I think the bolded items above, along with the "slipping clutch" are the culprits. I read the other thread where you complained about the horrid design of the Y-pipe and how it was just under 2.5". Not only that but the PP intake isnt exactly stellar.

 

I'd give the clutch a shot as you're going to need it anyways, but I wouldn't necessarily expect any major gains over what was already put down. Possible, though.

 

Well i am gonna have to say its more likely to be that intake manifold and crappy exhaust. So i would go with a LS6 intake better y pipe and a clutch just for *****.

 

my buddies cam only M^ put down 416hp. I'm sure your clutch is the culprit

 

Clutch & Re-dyno as simple as that

peace

 

my cam only 231/237 cam made 413whp

 

I want to see what it runs at the track. Dyno #'s can be overrated sometimes.
