Fuel Pump & Injector Install Dyno Results!! Well, I finally finished the install on the Racetronix fuel pump last Saturday as most of you all know from my thread, Good 3,000 RPM Launch photo in the dracing racing results section due to having some trouble getting the ring off the pump.
I installed the new 42 lb flow matched injectors last night and my good friends and I went to the dyno this morning for further tunning after they installed the new tune to scale the injectors.
The Mustang Dyno was programmed with 3,600 lbs. for the weight of the car which included me and my friend that was doing the tunning. I put 21 lbs of air in the M/T ET Drags and made the test run to make sure all was ready and the dyno was recording correctly.
I pushed on the brakes and clincked the line lock got the rollers going then shifted into 2 nd gear ran it up to 3,400 RPM's shifted into 3 rd and brought it up to 3,000 RPM's and stomped on the go pedal!
The results are as follows!
397 HP at 560 lbs. of Torque, the afr was 12.5, changed the program tried again!
396 HP at 502 lbs. of Torque, the afr was 12.8, changed the program one more time and tried again!
400 HP at 579 lbs. of Torque, the afr was back to 12.5, ready for nitrous!
Put the 15 lb. nitrous bottle in the car at 875 PSI turned it on purged the line got the rollers going move into 3rd gear brought to 3,000 RPM's and stomped on the go pedal and pushed the go button on a 45 HP dry shot at the engine and now my wife and I have a devil car. Most folks would say why even bother with such a small shot? I guess the devil made me do it!! LOL
429 HP at 666 lbs. of Torque, the afr came down to 11.9 safe for sure.
Thought I would post the result! Now it is time to go racing!!

That is the peak from the flash of the convertor, when I stomped on the go pedal sorta like a nitrous hit. I guess I should have moved wide open throttle to 4,000 RPM's instead of 3,000 RPM's since the convertor was not a lockup and it flashes pretty high. The torque was at 470 +/- on all three NA runs at 4,000 RPM's and on its way down however the HP was on it way up!
By 5,280 the lines crossed at 385 +/-. TQ going down and HP going up!
It was a interesting day!
