Thanks to everyone who helped me with all my questions about swapping pulleys on my S/C. i got my car dyno'ed today and i am very impressed with the numbers. 403whp and 327tq on a mustang dyno. i have a 2004 votech sc with the 3.12 pulley. it feels like a completely different car compared to the 3.33 pulley.

thats awesome!

What is your list of mods?

 

Great gains from a S/C. Congrats!

 

nice numbers man. i miss my vortech set up.

 

congrats on some nice numbers.

 

engine mods are:
1/2" motordyne spacer
rc 440 injectors
walbro 255l fuel pump
DC Sport Ceramic Coated Headers
Pro-1 Test Pipes
JIC Y-pipe
JIC Spartan DE Type 1 ST Exhaust

 

what ems are you running?

 

split second box

 

were the 440's a must?

 

from what i've been told, the injectors arent a "must" but rather recommended. you'll find a lot of information in this thread i started.

great info. thanks so much. i look forward to getting this done :thumbup

 

Good thread...I'm looking to go w/ a Vortech and either the 2.87 or 3.12 this summer and run the belt mod to prevent slip.

Nice numbers too!

 

Nice numbers

 

thanks everyone for the kind words. what do you guys think of my graph?

 

Great #'s but Looks too good for only swapping to the 3.12.. What were the #' s with the 3.33?

 

 

the car was never dyno'ed with the 3.33 so i'm not sure

 

Why didn't you just go with the 2.87?

 

i am EXTREMELY paranoid so i didnt want to be boosting too high. from what i read, people who had the 3.12 pulley were putting out numbers close to what i was looking for. i was really suprised when my car was dyno'ed because i was putting down more power than most on the 3.12 pulley and similar supporting mods. i would also prefer to have utec and some internal work done before moving to the 2.87 pulley.

 

inflated dyno numbers. 3.33 is so boring. 3.12 is interesting. 2.87 is fun.
