tuner said the my clutch petal was at the floor after ever run... my clutch is fucked...

tuner said it smoked a bit... thinking i fucked some #7 rings from spray before...

im not mad about the #'s. the car is running like a beast...

i will have track #'s 10/5... but my tuner does not think it will make a full pass with my clutch...

its stock clutch with 71k on it... lol

 

How much do you think you would have put down with the car in tip top shape.

 

asked my tuner that and he said it puts down what it puts down.... but he said he thinks my clutch is holding it back because its sliping up top...

 

not bad, with a LS6 intake you deffinatly would have made 400rw. Usally if the clutch is sliping you can see it because there will be a loop in the graph. It might be slipping a little but not to bad. Do you have the A/F chart somewhere? I want to see why there is a dip in your graph.

 

he had the a/f hooked to his laptop in the car not to the dyno... he told me it was dead on though.

 

I put down 357rwhp on a mustang dyno with pretty much the exact same mods, but stock pulley, oil pump and cats in my kooks y-pipe. It also peaked right around yours, at 6k.

If your clutch was slipping, wouldn't it be visible on the graph? Healthy numbers nonetheless. A couple of people have said back pressure is this cams enemy due to the fairly high overlap (16.5* I believe?) but you've already ditched your cats, maybe try a cut out? Ultimately I'd say it's a matter of the stock heads, and intake. This cam just can't get enough air from the stock motor. Still rocks nonetheless in my opinion.

 

Probably a stupid question, but he was still running a wideband, not piggybacking off of the stock narrowband, right?

 

my car has no mufflers.. so i dont think the back pressure is any issue... he said that its wasnt slipping bad but that he thought he smelled it and it was dead on the floor after each pull and having to pump it up to put it in a gear....

 

yes he had a wideband.

 

I would say that clutch is definetly an issue and needs to be taken care asap. That should have been done before anything.

 

That dip is still weriding me out. can you feel it when you drive? Or was it a once on the dyno kinda thing.

 

that is some sick numbers!!! hey but dyno #'s dont mean its what happens at the track i bet that car will haul a$$ on the interstate.. so how big of a dif. did it make in the *** o meter??

 

big *** o meter... pulling the motor to 6600 is fun... way more then 5900... its felt crazy on street tires... i might throw on my et's and go play...

 

nice numbers! try looking into an LS7 clutch maybe? they are reasonably priced, and are a great street clutch!

can't wait to come upside ya in a bad way around town!

 

going to milan 10/5 with the motorcity vettes... but my tuner said its not going to make it all the way down the track and hes going to bring his street tires with him so when i break my car he can take it home for me..... lol

 

If your clutch is slipping, why is the power still climbing???????????????????

 

i dunno... its slippin but not a whole lot... just enough to heat the fluid.... but still slipping

 

you need stg 2 LS6 heads. get rid of that ls1 manifold too. your stock heads wont be able to deliver the air that cam wants to give to the combustion chamber.

 

x2... lol if i had the money right now i would. hopefully this winter depending on work...

 

ok good. as long as you know your not getting the full potential of that cam with stockers in there.
