How Much Rwhp To Run 145mph?

[Quint]

Hey guys, as you may know I am bulding a stage 2 GN with Conleys Performance plus in houston. How much RWHP does it take on a mustang dyno and a dynojet dyno to run 145mph in the 1/4 at 3600 lbs. I know alot plays into this, but just basically rule of thumb for these cars on both dyno's. Thanks for the assist

Generaly speaking you will need 700-750 on a dynojet depending on the quality of the tourque converter. 500-600 will get the mid
130's 600-700 seems to be the mark for low 140's , Again this is general as I have seen many High dyno #'s that don't seem to get it done at the track . I also have had 600hp to the wheels on my dyno that ran over 145 because the converter never locked up in the short pull time .

thanks for the info, the turbo is q76 with stage 2 heads and the stall will be in the 4000 or so with a 400 tranny ready to rock

Yes, looking at June and learning to handle it. Wont take long, but will be fun. I just dont want to break something quickly, so will see alot more track than street and will probably only run 24#'s for a while, who cares if leagving power on the table, as long as it turns mid to 9.30-9.40's God willing

 

[Quint]

actually, at 24#'s mid 9.50's would be great?

I wish Eric's numbers were right. My car dyno'd 605 at the wheels and it's no where near 140mph. 3640#'s with me in it.

It should take 825 to 850 RWH to go 9.30 @ 145mph with 3600 lbs

Mine dynoed @745 And has run 9.20's @ 149.5

I have a customer that made 675 RWHP @ 21 lbs of Boost on my Mustang Dyno. The car weighs 3500. With a 1.35 60 fts he has run 9.40 @ 143 MPH,That was @ 23 lbs of boost.(figure that was 685RWHP) & If you add 20% for drivetrain loss, That equals 807 FlyWheel HP. Not all dynos are the same. Dyno jets read about 12% higher then Mustang Dynos.(thats my own personal exp. Other peoples will differ) Hope this helps.

750rwhp on my Dynojet will get you 140 give or take a few
