Small Dry Shot Dyno Results!
Small Dry Shot 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.96 HP 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 People 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!!

When you dyno a car with a ATI race convertor it is a little different then a stick shift car! On this little 346 CI, turbo 400 through a 4.10 geared 9 inch rearend on 26" X 10" ET Drags when you stomp the go pedal through the floor it is more like you are launching the car off the footbrake or on a big nitrous hit the torque jumps up and then slowly works it way back down as the car builds HP. Torque was over 485 at 3,000 RPM's! The car has run best to date 10.75 ET at 124.14 MPH NA on a TNT track day at Bowling Green KY. DA of +1,200 with a 1.44 60 foot on a 3,000 RPM footbrake launch! Weight of car on that day was 3,423 lbs.
As far as the line lock goes, I am not sure how you feel on the dyno but when you are going over 120 MPH's at 7,000 RPM's and you are six feet above ground and all you have is straps and some wheel blocks keeping you from launching out of the building I felt it was a good ideal to use the line locks for a little peace of mind!
Thanks!

The converter flash will show an inaccurate torque spike, so I still stick with saying the torque is inaccurate...sorry if this offends you, but it is not my intentions at all.
We have had a couple cars on our dyno over the years to know the difference of locked and unlocked converters and manual trans vehicles.
I did not read the post before commenting, but that still doesn't change the fact of what I stated.
I will say again and add to it.... very good #'s IMO for a MD dyno and the combo
oh yeh... the linelock I guess is a good safety. There are just to many crazy things that happen these days, so you can never be too careful.

wont you burn up your line lock if you use it for more than so many seconds at a time? I know a dyno does not take too long but I have heard it will mess it up. Just curious? Crazy numbers btw

By 5,280 RPM's the lines crossed at 385 +/-. TQ going down and HP going up!
It was a interesting day!

Convertor flash for the first 500 RPM's of the run it felt great and then settled down to just building RPM's! When I stomped on the go pedal if felt 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!

I have heard that you will get lower numbers on slicks on the dyno. i was a cincy speed when they were dynoing a turbo mustang and it was on some 17in slicks, and when they switched the front radials to the rear they picked up 60 hp. i dont know why but thats what they told me
