what type pf horsepower should I get with my mods?

 

Maybe 240 rwhp?

 

I'm no expert, but I wouldn't say much more than what Tay said. Most of your mods do not add any hp.

 

245 tops. But the 3.73's will add the equivalent of about 20 - 25 hp as far as an increase in acceleration.

 

You mean the Mach 1 grill delete does not improve the areodynamics adding .0000000000000000000001 hp

 

what would I need to get to 260 rwhp? and I know the Mach 1 grill delete tri-ax shifter, white face gauge does nothing for HP , but I was hoping that the predator, gears, plenum, tb, and CAI would add some rwhp

 

gears dont add HP.

i would say the weld up flows gave 1hp no joke.
plenum and tb gave 9 o the wheels
intake gave 5 to the wheels
and predator gave around 10 hp to the wheels.

so if i had ot guess i would say you are in the high 240 range maybe 248 maybe low 250's.

to get 260 rwhp you would need some pulleys and off road mid pipe such as a h-pipe i bet that would get around 260 rwhp.

 

oops I do have steeda UDP's forgot to put it in my signature but its there now. How much would a catted H-pipe or a catback system get me?

 

If you see my mods, I should be putting down about 255 - 265 rwhp n/a. I have no dyno results, but that is what I would realistically expect.

Spike, just to clarify, I did not mean to imply that gears add hp, only that they have the same affect of adding hp by increasing acceleration. Gears, actually decrease hp on a dyno by about 1-2. Some misstakingly say it is because of added friction, but it really has more to do with error of the dyno resulting in the gears not having a 1:1 in fourth. It is an unusual things that happens...they is actually not a hp loss.

 

Well if you are needing power, you can either go n/a or with a power adder. You can rack up some money going either route for sure. I have decided I am going with a supercharger myself, so all my money is going in the Boost pile

 

I need to get on a dyno so I can get the best tune for my car but I would guess from all the replies that I am pushing at least 245rwhp

 

why don't u just dyno it?

 

I plan to dyno it this spring just wanted to have a feel for what I should have

 

With my 99 GT, the power adders I had were a K&N air filter, Bassini Xpipe, Flowmasters welded in, Steeda UD pullies, 4.10's and pulled a 248 rwhp and 285 rwhp. All that with 90K miles, 35 passes at the track, and 158 of those miles were put on at Lowes Motor Speedway. Yes, the car was driven as it should be.

No Accufab Plenum, no TB mod, no CAI, and no Predator custom tune as you have. If I were you, look at getting an 03/04 Cobra flywheel and clutch, Steeda adj quadrant clutch cable, and alum. driveshaft. I had those mods and the parasidic loss is reduced therefore picking up some (not enough to count) rwhp but you'll notice it under acceleration.

 

So I guess I am pulling close to 250hp

 

Brfore I put the tune and T/B I was dyno'ed at 244 at the rear. I'm going to JDM with my SCT dealer later this month for a custom tune I'll post results later on as well. 244 is not that bad but I have the bug for more power.

 

well the flows don't add much and the underdrive pullies add like 10-15 to the crank and the gears don't give any HP they just feel like they do and a=make you accelerate faster and the airflow stuff will add like 12 hp. to the wheels i'd say 240-250.
