Currently: AP1 Comptech S/C with no A/C + Comptech Exhaust. Pushing 300whp.

I've been doing searches on the list of parts that I have in mind to push the car close to 350whp. Because of the combination of parts, its getting more confusing as I read on. So I was hoping you guys would shine some lights for me.

List of parts:
1.)E-manage or Ultimate E-manage (I've read post that there was issue with compatibility on the Ultimate. Have they fixed that yet?) What is the harness that I need to connect it?

2.)I have narrowed down to a 550cc-650cc injector for my goal hp. 550cc might be pushing it, so I'll probably go with the 650cc. Do I have the right size?

3.)10psi pulley. If anyone has the size of a 10psi pulley off the top of their head, I would love to have it.

4.)J's test pipe

5.)Aftercooler / Intercooler. Haven't decided yet.

Those are the list of mods that I have in mind to get 350whp. Mainly, I am trying to find out ff the Ultimate + 650cc injector would do it.

 

Ultimate woudl work, why not spend a few extra & get AEM EMS? You might want to get aftercooler to cool down the heat too.

 

But now that Comptech has announced their closure, I'm not sure how easy it'd be to get an aftercooler upgrade...

 

i hit 380whp and 220ft/lbs with a 3mm headgasket, 880cc injectors, 3 bar map, aem ems and 3inch pulley with a slipping belt.

You definitely want an aftercooler... if your going for more boost!

 

I've definitely getting some sort of cooler, but haven't decided on a after or inter yet.

By the way, what do you mean by that?

 

comptech is shutting down... its been around this site for a while now!

 

Comptech is going out of business.

 

3.5 in for 10 psi

 

Can anyone tell me if I got the injector at the right size? What about the harness for the E-Manage?
