Im in the process of installing my comptech sc. I got it used and it came with a 3.6 in pulley from Reichard Racing. Will this be ok with the stock injectors and the esm from comptech? I have an ap2. Also at what diameter of pulley do you need different injectors and a stand alone?

 

No this will not work, a bone stock ap2 could push up to a 4" Add Exhaust or larger TB etc and your fuel requirements go up so your pulley would have to be even less aggressive. Your stock injectors with the CT-rrfpr can only produce 300whp tops. Your going to be well outside that range with a 3.6" You will see upwards of 9psi. Also once you get up over about 7psi, you need to start cutting timing a bit, and you dont have that ability with the base kit. Injectors and engine managment is going to be your safe next step past about 7psi/300whp.

 

with Chris on everything

I ran sky high pressure for a while with the CT FPR but its far from ideal and eventually went to RC 650's.

 

Well it looks like I'll have to get a diff pulley now. Damm.. I thought I was ok with this pulley.. So I should get a 4-5 in pulley?

 

Ap2 comes with a 4.2" pulley stock, if you find a 4" that will be fine. One of those two.

 

I spoke to Chris at CT engineering and he confirmed...Im looking for a 4 or a 4.2 pulley and cant find one..Anyone know where i can get one? If not the kit is for sale..invested to much money already with shit i had to get that didnt come with it.

Will deff check them out...Do they have supercharger pulleys? Can I run a 4.25 instead of a 4.29 pulley? At what point do u start to need injectors and a standalone? 4?

 

Ended up getting a 4.25 pulley from horsepower freaks for a novi 1000.. It's meant for a mustang and is coming sited thy from Paxton, so I pray it works!

 

UPDATE

The 4.25 in pulley does in fact work. All was needed was an washer to be put on so the pulley doesnt touch the charger as its spinning. For all who are in need of the original pulley that came with your comptech supercharger, Go to horsepower freaks.com... You will find the pulley under the 96-99 Mustang Cobra. The pulley is for The Paxton Novi 1000... I paid $118 ( that's with 3 day shipping directly from Paxton)..Hope this helps those looking for the pulley.
