my post mod dyno results

[Dave T (BADVENM)]

Just got in the door from my 16 hour round trip to Woodhouse and back to retrieve my Sapphire snake. As mentioned in my stock numbers, these are on a Mustang dyno, I hope to take it to denver and get it on a Dynojet.

The mods include smooth tubes with K&N's, Belander headers, Corsa exhaust, Random Tech cats, and the Unichip with dyno tune. The car has about 1250 miles on it presently and for the dyno.

stock - 366.2 rwhp/393.3 rwtq (Mustang dyno, 457 rwhp/491 rwtq @ crank)
mods - 392.6 rwhp/430.3 rwtq (Mustang dyno, 491 rwhp/538 rwtq @ crank)

Not the best bang for the buck performance-wise but that Corsa makes such a sweet sound and the hissing from the K&N's is awesome. With highs in the 60s thursday I'm gonna take her out and see how she runs. I also had the Woodhouse modified MGW first strike shifter installed.

Now, I have my ABS and parking light icons glowing at me all the time. Is this standard.

I know the Mustang numbers will seem low but I wanted to throw out the differences between the stock and mods for anyone interested in the same setup as me. Looks like roughly 26 rwhp and 37 rwtq was all I could muster. Given the low mileage I'm hopefull these numbers will increase as I further break in the car.

I think you will have trouble with the Unichip. I had one on my car and it gave me all kinds of trouble until I had it removed.

just an update. The parking brake and ABS lights went off after a short period. Did a few highway speed runs and initially had some hesitation between 3-4K rpm, after 4K there was a short burst. Tried it again on another road and the acceleration was smooth. Not sure if the computer is "learning" but presently this has me a bit concerned regarding the hesitation in the mid to upper range.

Dave I would not worry about the numbers, mustang dyno's are notorious for being miss adjusted. Even factory reps most of the time cant adjust me properly.

Go to a dynojet and your car will pull a min of 420 with all your mods.

Regarding dynojet vs. mustang dyno, my GTS did 442 RWHP on dynojet and 385 RWHP, if I recall correctly, on a Mustang.

They have been said to differ by 10-15%.
