Dyno time booked
- Thread starter Red2000GT
- Start date
i want to see your n\a results ... did u get a retune yet?
The appointment is at 1pm and I'm planning on leaving around 10 or so. I'm hoping to give the car a bit of a chance to cool off before the first runs. I've got a basic tune to get the car drivable but half the reason for this is so I can get the guy that does my chips in Calgary,the info he needs to burn an even better one.

Well,things went good and I'm happy with the results.
Run#1) 261 rwhp / 264 rw tq / and the a/f ratio was an average of 12.1
Run#2) 257 rwhp / 261 rw tq / and a/f ratio avg. of 12.3
Run#3) 256 rwhp / 263 rw tq / and a/f ratio avg. of 12.3
N2O run #1) 324 rwhp/340 rwtq/ a/f ratio avg. of 11.0
!
N2O run #2) aborted
If you figure about 17% drivetrain loss thats right around 300-305 engine horsepower,which I'm happy with. However my a/f ratio is dead rich. The average numbers don't really show the whole story. It was fine at part throttle(14.7) but as soon as I went to full throttle,it would quickly go to poop. If you take out the part of the graph that includes the part throttle portion,the averages drop(by my calculation) to around #1)11.4 #2)11.4 #3)11.2 . So some adjustment there should net me some decent gains. I'd hope about 10-15 rwhp,maybe more. The nitrous run was with the 100 hp jets and the bottle pressure was 1100 psi. The first run was with the flip chip in the normal(OFF) setting. I forgot to bring any other jetting with me so I wasn't able to tune it a bit by decresing the fuel jet size. The 2nd run was with the chip in the nitrous position,which has the a/f ratio fattened up for safety purposes but it went too far. I cut it short cause it was loading up the motor,making it stumble and was getting worse. The a/f ratio was actually at 10.0 and falling when I stopped. So definately lots of a/f adjustments to be made across the board,and all for more power I hope.
One thing I noticed was that the torque seemed kinda low and I'm not sure if it's just a Mustang Dyno thing or if perhaps a setting on the computer was wrong. I was expecting about 20-30 more foot-pounds N/A and about 35-45 more on the nitrous,I guess we'll see once the guys have received more than just the basic training on the dynamometer(spelling?).
Also temperature inside the dyno cell was about 19 degrees celcius but the engine temps were not particularily low. #1) 200 degress F #2) 220 degrees F and #3) 235 degress F. (1/2 to 3/4 up for you guys without a aftermarket temp guage)
I guess I'll have to make another trip once I get my chip reflashed again. I'm thinking of going to a Diablosport Predator tuner to gain some self-adjustablity. Then I can dial it it perfectly myself. If I've left anything out,just ask and if I can I'll add the info.

Oh yeah,and it's weird and fun at the same time to watch your car run to 150 mph without moving! And 1/4 mile runs are totally different than at the track. We had a good laugh when I tried to make a nitrous run,the car spun the tires in 1st gear,on the shift it bounced back on the tie downs and in second it kept spinning the tires cause the car was bouncing violently on the straps,spinning when it bounced up,the straps would pull back and the tires would grab,causing it to bounce back up against the straps. This went on for about 4-5 seconds with the rpm holding at about 4500 so I shifted to 3rd to calm it down,which it did,but it says I ran a 14.99 at 97 mph,LOL.

Get the Diablo Predator to fix your problems....You can make adjustments where ever you are on your own time too...like SIR.. I'm very happy with mine. You should see some sweet gains with the diablo...(Diablo Tune) like 15 more horses and rw tq.. and then you play with your timing and air/fuel...you should even see better numbers. Plus you have fan options so you can make your car run cooler = more power..
My stock FAN settings were:
high_speed_fan_high_load_temp_to_turn_on........22 8
high_speed_fan_off_ect............................ ..............224
high_speed_fan_on_ect............................. .............228
low_speed_fan_off_ect............................. ..............206
low_speed_fan_on_ect.............................. .............214
I changed them to:
I set ECT1 (high)...................................................... 194
ECT2 (high)............................................................. 194
High Speed off......................................................... 190
Low Speed on......................................................... 186
Low Speed off........................................................... 184

you should roll LT1s already.. and ls1's only have 320 hp, youre not quite there yet, but almost
