Eurocharged 175mm pulley compared to 168mm
Currently have a Kleemann 168mm put down 442whp, 488wtq on mustang dyno.

Changing to a ec 175, 550 injectors, fuel rail, kleemann headers will I get close to 500whp mark?

Reading up on the kleemann pulley it's ALOT lighter than any of the other pulleys. Wonder if my 168 and the new 175 would be close? Any input...

Maybe I may just keep the 168 lol fawk

well since our mods are gonna be almost the same, you can wait until I do mine and then see what kinda power my car makes... i'm going with a 175mm pulley... btw does anyone know if I need a smaller wp pulley for a 175 or will stock work?

Hmmmm no point of going through all the hassle of changing pulleys etc etc for 10 tq...

Looks like I have a brand new EC 175 pulley kit for sale lol Stupid impulse buys...

Exactly my point ! not much different. And you can get the new smaller SC pulley so why go to 175. I think 168 is the best combination. You just need to add the Kleemann Header and your car will run 500whp mid 11's
