I'm wanting to go with a smaller pulley for my comptech SC. I've got a few questions I can't find the answers to so I'm hoping you guys can give me some help or point me in the right direction.

First of all, where would I get a smaller pulley? I've gone down a size to a 4.25" pulley now, but I had to buy that from someone else.
With my intercooler and the new pulley, I'm basically running the same HP that I had with the stock pulley. So where would I go to find a smaller pulley?

Also, I've got my FPR pretty much cranked up. With the smaller pulley, it's almost obvious to think I'll need more fuel. Would I need to get a new pump and/or regulator? I have no idea what the one that came with the SC kit is capable of since I bought the car with it already installed. So if the answer is yes, any recommendations on where to get one, and which would you get?

Any other things I might need to consider? I'm upgrading my fuel injectors to 550cc injectors. I've got an AEM EMS coming.

Anything else I might not be thinking of?

Thanks in advance,
Dave

 

http://www.tech2motorsports.com sells a lot of comptech goodies. talk to drew if you need anything.

 

....how are you determining the correct setting for your FPR? What makes you think it needs to be "cranked"?

 

the guy that tuned my car with the V-AFC says he had to crank it up. This guy has tons of experience tuning domestics, but little experience with imports. He also "knew everything" about the V-AFC and wanted to argue with me on the fact that the V-AFC couldn't add fuel, only subtract it. It took him an hour of telling me this and that wasn't working before he finally realized I was right. I'm getting Sean from TorqueFreaks to tune my AEM EMS when it gets here...so I guess I never really thought about the fact that the "genius" that tuned my car previously probably turned the FPR up more than he had to. I'm going to throw the smaller pulley on there (If I can find a place that sells them) before I get Sean to tune my car, so I'm just trying to make sure I have everything I need before he flys out here to tune for me.

I guess my goal is to try and push 9-10 lbs of boost before considering the intercooler...I understand I'll lose a little of that.
You guys think the guy that tuned my car was exagerating (sp?) the FPR? Should it be ok trying to run 9-10lbs? What about the fuel pump?

Thanks guys!

what's the expected max pressure at the intake (downstream of the aftercooler)?

 

I'm hoping to have 8-9lbs...aiming for 8 but I want to make sure it's not less than 8.

What size pulley would I need for that?

 

If it were me, I would wait on installing the pulley until you get the AEM EMS and injectors. Do them at the same time.

 

The plan is to drive to Alabama the day before I meet Sean, and try to install the pulley and injectors...and then let him install the AEM EMS the next day and go to town with it.

I'm absolutely clueless on where to get a smaller pulley for a comptech SC though. I want to run around 8-9lbs of boost after the intercooler is taken into consideration.

I'm also worried about being able to supply enough fuel. I don't know the specs on my fuel pump or FPR.

so my questions are:
1) do I need a new fuel pump or FPR to supply the fuel for that expected boost, or should the ones I have now be able to handle it?
2) Where in the world can I get a smaller pulley...and what size for 8-9lbs of boost? I've done searches all over the internet and I can't find a thing.

thanks Juan,

Just out of curiousity, what fuel pump are you running?
