After talking to a few people (Puerto ricans) with similar setups, I've decided I want to take my Vortech to the next level, on a budget. I have an A'PEXi VAFCII, AEM FPR, plan on ordering Inline Pro 575cc injectors, and an ASP 4"pulley (~12PSI). I plan on keeping the compression stock (I can get 94 octane everywhere around here). It will be dyno tuned, and kept as conservative as possible.

I'm just wondering if anything is being overlooked and if there is anything else to be considering.

Also, do you guys think 575cc is sufficient enough?

All goes well I'll be back with dyno sheets for you guys soon.

 

big thing...EMS?

575 cc in my opinion? Pushing it or not enough. I have 750 cc in mine. I think I would have maxed out the 650 cc on 10-11 psi...give or take.

Good luck man.

 

I was thinking bigger too. As from what I hear, it's easier to take fuel away from bigger injectors with the VAFC rather than add more to smaller injectors.

It is a budget upgrade, I already have a VAFCII and an EMS is $1500+.

 

575 cc are plenty big enough, 750cc are overkill for almost any S2K SC application. My rc650's will be good til over 400hp on my TC setup.

 

If you think you'll want more power, and most do, save up for the EMS and run bigger injectors and more boost
