Yesterday I ran a 12.3 @ 113 with a 1.7 60' with the mods in my sig.

I'm still on stock clutch and somewhere in my run the car is dying off but I was also on almost a full tank of pump gas.

With race gas + about 2 psi (boosting about 22 right now) Will my stock clutch be able to handle much more then what it already is now?

also, any stock clutch 03 evo's in the 11's?

 

I Ran 26 Psi On C12 Not Tuned For It @ All Car Def Went Faster & Safe Too I Pulled Some Logs & They Were Good You Should Def Be Fine

 

I guess it depends on how worn your clutch is. If it's on it's last leg, 2psi definitely won't help the longevity. I guess there's only one way to find out. Btw you can just mix in a few gallons and up the boost. I've mixed 100 octane in my own car and upped the boost to 25-26psi and it ran well.

 

Mine was fine until I was making 315 wtq on a dynodynamics dyno... it couldn't grab the oem clutch when you slipped it.

 

I have at least 330/330 and it grabs fine. There's also a 400+ guy here in Dallas that is still on the stock clutch.

 

Im on a stock clutch running 24 psi all day, with 45k miles on the car and no problems what so ever...

 

I ran 350hp on the stock clutch for a bunch of open track days. I wasn't launching the car though.
