Wish I could man. I have to pay for books/tuition in a couple weeks so I'm broke atm. How much would you want for the long tubes and x pipe? Probably still out of my budget but let me know.

^ I'm not positive on the belt size but I believe that's the one I have. Might be a dumb question but where can I pick up that 3.12 pulley?

Also as far as fuel pumps go which one would you go with? The two I'm looking into right now are the svt focus pump and the styker 340. Will I need a bap to go along with those?

On ebay, from Vortech, from superchargersonline.com. You can get the 3.12 anywhere. There are used ones floating around on the boards. I personally would not put the 3.12 on an Si. You'll be at 12psi, which is too much for a stock motor. Division X 340 or KMS 340 pump. Both require minor modifications. My svt focus pump was at 92% duty cycle at 356rwhp. I added an bap and now its at 72%.

^ that's a good point I kinda want to stay under 12psi lol how difficult are those hp cams to install? Could the guy installing the supercharger do it without too much work? I'm worried the sc install alone is going to be a ton of money.

I don't think 12psi is to much. It's only hitting that 12psi real quick. I'm making 13psi in the cool weather and no hiccups

Is that 12-13psi you are hitting combined with a intercooler and meth injection? I always figured that meth injection assisted with the cooling and in a way increased the octane rating somehow all reducing the risk of detonation. Or are you making that 13psi on the intercooler alone? I always thought 10psi or so and the tune was the gamble on these stock motors UNLESS you had aftermarket heads or cams or a combo of to help with the breathing/efficiency.

That exactly what meth does it lowers the AIT while dramatically increasing the octane rating.

13psi is on the meth. But the iats are cool enough to where the meth isn't doing much besides raising the octane.

Op you won't need 12psi with cams. You'll be over 400rwhp with probably 8psi and cams.

I was at 430rwhp with no intercooler and MPH cams at 13 psi.

If the meth is running properly it is pretty much the equivalent of running race fuel as far as octane rating which will allow him to getaway with a much more aggressive tune even on stock internals.

With long tubes and blower cams it will make power more efficiently and you can make the same power you want on less boost, leaving you a lot more room to grow if you ever build a motor

how did you like the hp cams? I don't really know anything about them cuz I wasn't planning on doing anything besides exhaust but it sounds like they'd be worth the money. Just sent you a pm btw.

Might just go with the prochamber and the hp cams.

Have you considered doing the supercharger install yourself? That can save you enough money to have the cams done.

Never drop a cam in without degreeing it no matter what anyone tells you. This is a Rookie mistake which can cost a person thier entire motor in just a few seconds. I have read threads on this forum this year of people putting in cams 180 out and starting thier motor if they would have they degreed the cams this would have never happened.
