LT1 dyno, my first time! So i ran my 'bird on a Mustang Dyno at Morrisville State College during an auto show today. I was expecting to pull around 250hp (mods in sig) at the rear wheels, but to my surprise, my best run had these numbers:
274 hp @ 4467 rpm
347 ft-lbs @ 3194 rpm!
So i'm glad my first dyno runs went so well, and it only costs $20! I wanted to try a run with my cut-out open because I still have the stock intermediate pipe, but we didn't have time to re-route the exhaust hoses. An '01 ZO6 who went after me only pulled 337 ft-lbs, so I'm beginning to wonder it my numbers are normal. The guy who sold my car to me said it was "all stock except for the performance chip and the corvette heads!" I just assumed he didn't know what he was talking about. Maybe it has a Jet chip or some kind of tune done to it.

Pull 1
269 hp @ 4202 rpm
347 ft-lbs @ 3094 rpm
Pull 2
274 hp @ 4467 rpm
347 ft-lbs @ 3194 rpm
Pull 3
269 hp @ 4631 rpm
334 ft-lbs @ 3796 rpm
There is a big difference in rpm. The only error i can think of is they have the wrong weight listed. They have it at 3750 lbs when i told them it was more like 3450 lbs.

It would be a neat feature for dynos to measure weight too, maybe on one with rollers for all 4 wheels. I honestly was expecting about 250 hp and 300 ft-lbs at the wheels, so maybe my numbers are inflated. I weigh 200 lbs (all muscle!) so the car would be 3650 lbs with me in it, so 3750 isn't too far off.

my 1st time dyno'ing I bought a full bolt on lt1 from an older man who said it has a hot cam . Dynoed 302rwhp. Very lean. New 30# injectors, racetronix fuel pump, holly fpr, dyno tune. Corrected 340@5700rpm . This was done on a dyno that LS1's with lid and filter barely break 300rwhp. Keep modding, but remember to tune. Since your in new york, take a day road trip to kaltech, put your car on the dyno get a tune.
