This car definitely feels like it'S got more go then that. My SRT4 Dynos in the low 300whp and its a couple hundred pounds lighter than my Mustang, so if my Mustang could keep pace with it...

Other factors to consider:
Won a couple races including:

LS1 Z28 from a roll he actually hit WOT when I was behind him and I came around and passed him up like he was going out of style. Talked to him at the next light and he claims running a best of 13.1, but since he ran the 13.1 he had installed long tubes and an ls6 intake manifold.

03/04 Mach 1 from a roll we raced twice and the first time it was the same thing he came haulin ass right passed me didn't try to line up, so I caught and passed him. Then we lined up I waited for him to hit the throttle. Passed him no problems

01 Acura NSX This was a run the way a run should be we were at a red light I look over and he looks back and revvs, so I rev back. The light turns green and we go. Even with a little wheel spin and a slight grind on 1st to 2nd I statyed ahead of him the entire time. We raced to about 100 and I had him beat by a car or so and I had my gf in the car, so carrying an extra 120lbs over normal.

04 WRX STI from a roll on the freeway. I was cruising down the freeway in the fast lane going right about 65mph. This guy in an STI cuts over to my lane really quickly and proceeds to cut me off and barely misses hitting a car in the lane to my right. As soon as I seen him start to merge quiclky I down shifted and waited to see what he was going to do. As soon as he got into my lane he was on the throttle hard, so I nailed it, caught up, and passed him up. Then I slowed down to let him come up and try for a line up run, but he wouldn't come line up with me he stayed behind.

If my car can do all of this with under 300rwhp I'd be amazed and happy at the same time. I'm still building a new motor on the side that will be paired with all of my current components plus hci then it'll be insane

Guy on the internet quote "car went 12.47@112 2 months ago. Mods are 1 5/8 shorties, off road H-pipe, 2 1/2 cat back, 3:73's, SN2000 8 pounds of boost, and 26/10.50/15 ET streets. Everything else is completely stock, injectors, T-body, MAF, all stock."

So lets say 3400 pound daily driver weight mustang and 112mph trap speed...

Both calculators I run it through estimate 330-340rwhp

Since all of 1st and 2nd have to be fearhered and itll still get loose in 3rd easily and chirps 4th on wot shifts taking it out on street tires would not do my et justice, but I could see what my trap is like and have a.vood idea of et with drag radials

a good set of 275/60/15 drag radials could help

damn..why you gotta put me out like that...????

I have heads and cam though so that gives me an extra 104.2 RW

---

You know what I assumed he had a GT40 h/c/I like you. I will give him the benefit of the doubt and spot him the 4.1 rwhp.

My new guess will be 284.1 corrected rwhp

Put some slicks on it and do a couple 4000 rpm clutch dumps and run it through 5th gear at WOT not granny shifting. If it breaks the clutch or trans then you know you have at least the max cap for the broken part!!!

(disclaimer: I am not responsible for anyones car breaking or tickets incurred by actually trying my horrible advise. However, if actually tried. Please YouTube so I can get a chuckle.)

One convenient way to calculate the power potential offered by any supercharger is to take the power output of the normally aspirated motor and multiply it by the boost pressure as a function of atmospheric pressure . A normally aspirated motor runs @ an atmospheric pressure of 14.7 psi , all you have to do to double the power output of the motor (in theory) is to double the pressure to the motor. Meaning that if your normally aspirated motor produced 300 hp , all you have to do to reach 600 hp is to double the pressure or supply 14.7 psi of boost using a supercharger .If you supply only 7.35 psi of boost , you should see a corresponding power gain of roughly 50 percent since 7.35 psi is 50 percent of 14.7 psi. The simple math formula is as follows ; Supercharged hp= NA HPx boost pressure/14.7+1.

there you have it , anyone wanting an hp guesstimate . Its all there

Blower should add about 8-10 HP per poundof boost so if you are adding about 64-80hp. With your mods you are prolly putting down around 250 HP at the crank. Add the HP gain from the blower and you would be at 314-330 at the crank. You will loose about 15% through the drive train so that will put u at around 267-280 RWHP.

As mentioned above.. Pay a visit to the dyno and find out fer sure :-)

Thanks for all of the info guys. I doubt I will be dyno'ing this combo since my new engine should be ready pretty soon, but if I can find an inexpensive dyno event I might go just out of pure curiosity
