My car is running stock Vortech supercharger with a Toda 2.2l low compression stroker kit. Everything else is stock and the cat is still on. It makes just under 300 RWHP now I was thinking to take the cat off and change the pulley to 4" for 12.50 psi boost about double what it is now. So 350RWHP/400BHP+ is the rough target, is this realistic?

I know there can be clutch problems so the clutch has been changed but will anything else need doing?

 

with 12.5 psi, you should be well over 350whp, i'm at 9psi right now and i'm hitting 345whp on a dynodynamics..

 

How's your low end power/torque with S/C and being stroked? Any noticeable difference?

 

heres my dyno, bottom end torque does feel better driving. I was a bit dissapointed with the results but then I guess the low compression stroker kit on its own doesn't do much it just means you can run a lot more boost

 

Oh the possibilities... Good luck with everything!

 

just be very careful with the intake temps on higher boost

 

head gasket.

 

a headgasket isn't needed since he already has low CR from the stroker.

 

my cars in england so its usually cold and the vortech has the aftercooler but have you got any other tips?

 

^ yes, up the boost already Seriously though, you might want to go a step or two colder with your spark plugs. good luck!
