Not sure how realistic this is, so I thought I'd get some input..

Planing on doing MACS with ORP
removing the screen on my MAF
and getting a ported TB


think I can get 20 or 25 rwhp?

Thanks in advance

Without H/C/I the throttle body will give you maybe 2-3 hp - the descreened MAF is a little better than stock 1hp (maybe.
MACs are worth 15 on average. Some people gain more some less. I would do the collector mod on them and clean up the welds to try and make sure you get the full 15 hp. With those three mods you should be around your desired 20 hp.

I'd say 15-20 for sure. Good luck! <img src="graemlins/gr_cheers.gif" border="0" alt="[cheers]" />

I went from 309 rwhp to 338 rwhp with adding MAC headers with ORP and ported TB. So that is a 29 rwhp increase.

Those are some great #s
I guess it just depends on the car...I've seen someone get 7rwhp from a ported MAF, and I've seen someone get only 13rwhp from headers...so I guess every case is different..

I'm just hoping for that 20rwhp, at least!
