Dynamometer Results & Comparisons - Was bored so I dynod the car this weekend.

Seems a little limp for power towards 6400 RPM, most likely due to the stock fuel pump and fuel filter.

NICE curve but looks a little light overall. Replace fuel filter once a year. Stock injectors? Replace/upgrade that pump (with injectors) and retune. I see the rear and driveshaft but still think you should be solid 410+ with that setup IMHO.

I know dyno's can vary but I think those numbers are way low. Even through a 12 bolt. I made 380/380 with the mods in my sig. Id epect 415-425 with your setup.

The dyno I was on reads low.......definitely lol


I have 42# injectors. I know I definitely need to replace the filter and fuel pump. On most other dyno's I read 410-415whp SAE corrected.

You should post that graph then. Not the graph the reads 25rwhp low, lol

If your track times in your sig are from this same setup then your power is spot on...should run that with that power.

That could be true but it also depends on the DA of the track, race wieght, driver skill's etc....

My very first pass in my old H/C ws6 was 12.7@113 haha, granted the DA wasnt great either. With a shift light & more practice I got it down to a 12.1@117 in the same crap DA. Then in good DA I got 11.9@120 out of the car. I made 416rwhp, full weight, full street setup, 10 bolt.

The same day my buddy with a tr230 cam & bolton's full weight WS6 went 11.6@120. He had Skinnies & slicks, dumping the clutch at 5500rpm (12 bolt) & power shifting. And he could hit the gears spot on. Lots of variables.

They are but it was on drag radials that i heated up way too much. I spun first gear and over revved second and third. Havent had time to go back.


That was also the second time ive been to the track on that setup. Track is englishtown in nj

People get too mixed up in dyno numbers, it makes what it makes, do your regular maintenance and retune for an improvement not to hit a magic number. It may of been hot that day, high humidity, blah, blah, blah. To many variables.

Yeah i dont care what the numbers are honestly. I threw it on to check the curve.

Its funny, because plp will say your dyno numbers are low, but 12.2@117 is very good IMO. A lot of plp are cracking 420++rwhp here and they just cant back it up with decent times. Internet hype crap gets old sometimes.

I did 12.6@116 on the track, back in the days with my H/C 387rwhp 5.7l ( mustang dyno). This was with a 2.4 0-60, bald tires and 3:42 . Its was a killer setup on the street, faster than a 556hp CTSV and a 10' GTR.

I'm sure your car is a beast!!

FWIW, the old car in my sign dynoed 373 to the wheels n/a and 506 on the gas and ran those times. Needless to say, I always tell people the dyno is for tuning.

Yeah I'm not a huge numbers guy when it comes to the dyno. All I really use it for is a tuning tool and to see if there are any issues with the car.
