CorruptedDemon60

You got the OBX headers! How you like them. Hows fitment, quality, install, etc. Your the first one to use them. Thanks.

I recently Dynoed on a cool 65 degree shop temp at 507rwhp and 500rwhp on the second pull, and was told I'd need #60 s. I'm going to go down to a less powerful pulley and try for 460rwhp or so. Erik

The fitment wasn'tterrible...and the quality isn't as bad as people like to talk..but I'll leave those opinions to those people...All I know is the sound opened up and they are going to put me over 500rwhp after I change my injectors...

Oh do you already have a GT500 fuel pump installed in your car now? Then I would say you either need a boost a pump or an additional pump if you want 14 psi...I would say that just to be safe, but you could get it on the dyno and find out the single GT500 pump is enough, but my guess would be that you would need the additional pump or a boost a pump...

The gt500 pump comes with the HO whipple kit and on brenspeed's site as well as Lethalperformance it says that the pump is good up to 600 rwhp. Got the 60# injectors on the list and the harnesses for them tooWhat psi are you at and do you have a built bottom end for that power???

Black05StangGT

I am at 10.5 psi...and it sounds like you only need injectors...their is a guy on ebay selling the 60# injectors with the EV6 style connector i would consider getting those... I am actually in Atlanta and MPH is in Cartersville...so thats why I go there, although I would probably go there regardless of where I lived...lol

Where did you get your OBX LT's? They come with an o/r mid pipe too right?

Black05StangGT

I got mine on ebay for less than $500 shipped...they come with two different H-Pipes...One has resonators on it and the other is just straight through...

Jesus. Less than $500 shipped for LT's + mid-pipe! Why don't more people go this route?
