IM wanting 300+ horses out of my 99gt. I'M putting on a o/r H pipe and weld on flows. Have a K&N filter now. I'M looking at getting a mach 1 hood and scoop, Underdrive pulleys, accufab and 75mm TB .I drive this car 500 miles a week and still need a little mileage and dependability. what else do I need to get 300? :shrug:
Sorry about the stupid questions but im an old school drag racer. im use to big block chevys that are very easy to get 500 out of but with 5 MPG.
 
R u looking for 300 flywheel or rear-wheel hp? Cus there's a big difference as you probably already know. At the flywheel isn't hard with just boltons, but at the wheels is gonna take more than the bolt-ons can provide. I'm not to knowledgable on the modular motors though, so maybe someone else can give you more info.
 
hmmmm, I think he means rwhp... and yeah, cams and... hmmmm, who on stangnet makes 300-320 with a GT?

-edit- oops, nevermind, flywheel is way easier. Your not that far right now... Get all the cheesy bolt-ons.

yeah, agreed.... what does that mean he needs on a dyno, like 260 or something? whats the drivetrain loss?

Usually like 15% or so, more with an auto. Ummm......... as for the exhaust getting you close, they dynoed a 4V before and after full exhaust and it gained 23 rwhp. That was LT's o/r x-pipe and some catback. :hail2: So that was maybe 30 at the flywheel? I wouldnt think it would be as much with a 2V, so it would help out tremendously no doubt, but you'll still need quite a few bolt-ons. :nice:
 
When my car was n/a, I had a catted x pipe, dynomax cat back, ud pullies, 3.73 gears and a eec reflash that put me right where you want to be. Cost me about $2300 but that included a dyno tune.

Out of curiosity, I know the gears had nothing to do with increasing the hp, but I believe neither do the ud pullies. Don't they just free up more of what was there already?
 
FORGET what all these people say!!
the easiest way to go over 300hp+ with out spending over $3000 is NITROUS. no other way


oh yeah i got a dry kit that can sell you for cheap, pm me if interested :D
 
I have 290hp at the rear wheels which is fairly close. I think a slightly better tune might push it closer. It can be done, and wherever the $3000 price tag comes from in the post above is a bit off.

Mine would be easily over 300 if I had some headwork to go along with the cams. Another cheaper thing would be an electric water pump for about $325. There have been guys pick up about 7-8hp with them on Modular Depot from the loss of parasitic drag on the belt.

Basically I have:

Cams and Springs $700
Headers $300
O/R X pipe $150
Catback $300
Pullies $100 (used)
Upper Plenum $170
CAI $200 (not needed)
75mm TB ($190)

$1910 invested in performance parts.
