These are my plans for hitting 300rwhp.

1. L/T headers
2. Catted H-pipe
3. American Thunder Cat-Back
4. U/D pulleys
5. K&N FPIK Gen II
6. Computer Tune
7. Accufab Plenum
8. Accufab Throttle Body


Will i hit 300rwhp?

 

[JonJon]

No. You'll need cams.
You'll be like 270-280rwhp maybe with those mods.

 

[Redfire03GT]

Nope. That'll probably throw you in the range I was at, when I hit 260. 270 tops but that's pushing it.

 

[01mgvert]

With my automatic, I dynoed at 249 rwhp (see list of mods below). It would have been 259 rwhp with a 5-speed. I believe that I added another 6-8 rwhp with my new Magnaflow catbacks. 300 rwhp will take custom cams and/or p&p heads.

 

[JonJon]

Oh, I'm 255 without the LT's or a tune.
UD pulleys, X pipe, cat back, MAF, intake plenum, tb.

 

[krly79]

might as well put that money towards that Kenne Bell you want.

 

[Beau]

here's a better way to get to 300 rwhp.


supercharge the car.

Without a power adder of some sort or internal motor work, you will not see 300rwhp on a 2v 4.6ltr Modular V8 found in our Mustangs. Now, if you decide to go with VT Engine stage 2 N/A cams, full length exhuast, a bit of intake work, pullies, and a dyno tune, then yeah, you "might" hit 300rwhp. Then again, you may only come close.

As the guys said above, best bang for the buck is a power adder for quick power, however, if your motor isn't built to support the power adder, rest assured, the motor will be on borrowed time. Just thought I'de give you that heads up warning.

You could put an LS1 in it and start with 300 RWHP.


It's a shame the LS1 isn't Fords motor. That motor is sick.

I would love to have a GT with an LS1. Then put a cam, longtubes, and a lid on the bitch and have 400 RWHP. If only somebody else would do the work.

 

[mity2]

get LM or magnapack instead of American thunder. Baffled system is more restrictive then straight through system

I agree with all you guys , here is how I see it.

L. Tubes = 15hp
Midpipe = 9hp
Catback = 5hp
Pulleys = 5hp
Filter = 4hp
Tune = 10hp
Plenum & TB = 12hp
EQUALS = 60hp + 260hp = 320hp X .85% = 272 RWHP

This is assuming a 15% drivetrain loss. Hey 320 at the fly ain't bad. Should be able to stomp most of what is out there.

I've always wondered what a lid is for the LS1's.

 

[JonJon]

I've always wondered what a lid is for the LS1's.

it's like the intake tube (on our cars)

 

[wanta5.0]

it's like the intake tube (on our cars)

Yeah, and they usually gain 15-20 hp at the wheels from just an aftermarket lid.

 

[WRXracer]

my friend put an offroad pipe on his LS1 and its a whole new car.. its almost as if god made that engine..

 

[WRXracer]

if you get heads and cam you will make over 300 RWHP.. but your going to rev higher simaller to a cobra engine..

 

[BLKsteeda]

With these mods on my 01: Steeda CAI, Accufab T/B & Plenum, Steeda Intake Spacer, VT Stage 1 Cams, Steeda Underdrive Pulleys, Steeda Timing Adjuster, Bassani O/R Xpipe, Steeda Stainless Cat Back, 3:73's, Superchips tuned by Steeda my car makes 284RWHP and 302RWTQ.

You are going on GUESTIMATES, you'll never pull that much HP out of each one

 

[Ghostface]

really? I can definitely see a possible 270 RWHP from those mods, maybe not like that from each one, but 270 is likely.

 

[Craig Mack]

Bah, Ellas Jaun is not Gods gift to engines...

All you guys need is 2 more cams and 16 more valves....300rwhp is a lot easier to attain.
