Default Need some advice.

Hey all

we fellas, i'm stumped. I really want some more power but can't think of anything to get me where i want to be. I know i will get a new m&h fuel pin, and a airdog fuel pump, but after those mods i can't really think of anything. I don't have the money for twins right now either.

thanks for any input.

Don't forget about your tranny. More power is great, as long as you can get it to the pavement. Shift kit and TC would come in handy, I reckon. What about adding more air as well, since you have big injectors and a bigger turbo, maybe trick out your cold air intake. Bumping (or spacing) your timing would help too.

I can count on my W/M for any where from 40 to 50 RWHP on the dyno with a 51/49 W/M mix.

fuel and air make power.More ,cooler air is always better but adding fuel is the ticket.Blocking wastegates.Pulling in cold air from the wheel well.larger pipes larger intercoolers and intakes.Nitrous is nice,but it expensive and unless your a track/dyno queen ,i wouldnt bother

You're not getting full fueling. With a stock/OEM 12mm injection pump typicaly "Maxed", you should be much hotter than that.
