hp guesstimate game

bucky · 05-02-2005, 03:41 PM

i have nowhere to get a dyno at, and want some people in the know about mustangs to give me a fair guesstimate on how much my car is putting out ( in horsepower, get your mind out of da gutter!)

2001 gt auto
1. K & N COLD AIR INTAKE
2. "3.90" motive performance gears
3. gt intake spacer
4. steeda cat back
5. accufab 70mm throttle body and plenum
6. diablosport tune

here is my estimate: 279 going off the following:
car is stock 260 hp from what i have read
1. 2hp
2. 0hp
3. 2hp
4. 6hp
5. 4hp
6. 5hp

i am about right, or am i lowballing myself?

i think everything is right minus the plenume dont people dyno 8hp or more with that thing? and tuner i would image is more like 10hp. but basicly flywheel its like 280-283 i guess?

I think your numbers that you added are a bit low. Those or closer to rwhp. I am with Dustin. You should probably be putting down around 280+ fwhp and around 250 to the ground.

One thing to consider, is that on a dyno the 3.90's are gonna cost you about 8 rwhp. That's right. You will actually loose hp. It is sort of a fluke on the dyno and is really not real hp loss. Except for perhaps 1 or 2 due to friction loss.

Also, what wheels and tires do you have? They can affect dyno numbers too.

280 is good.. i have fuzion zr1 tires, i think thats the name. mach 1 rims.

i was hoping ( but in reality it wouldnt happen) that the diablo tuner plus all these mods would be closer to 300. i heard really good things aboutthe diablo, and it brought the car to life.

Every car reacts a bit differently. I know the SCT xcalibrator really woke my car up.

I'm hoping to be at 400 rwhp on a mustang dyno soon though :evil7:
