Drove the car down to the Friday night NOPI test n tune to try out the new converter. I had Fred at Midwest rebuild my PI converter – the fins were bent and it was blowing thru on the top end - it was in the car for 5 years! It took us two tries to get the stall speed right, ended up with a 3400 stall.
First run, I started loading it up on the line and it immediately started spinning thru the brakes – damn the converter is tight! So, I let off and backed up to run again despite the dirty looks from the starter!
I brought the RPM’s up – cautiously this time – and let ‘er loose. Launched kinda soft, then it came alive, ended up with a [email protected]! I was happy as hell with the MPH as it eclipsed my previous best by a ton! Here is the breakdown:
60’ 1.560
330’ 4.182
1/8 6.337
MPH 114.61
1/4 9.778
MPH 141.16
Next run, I tried a 75 shot for the launch and went up in smoke! Made one last run with the normal 50 shot launch. I launched soft, 1.69 60’, and ran [email protected]
I am really happy with the speed, but got to get used to the converter and get the short times down a lot. This is a heavy street car – 3530 lbs – heavy wheels, TT brakes, etc. I need some lightweight wheels and brakes on there, but I like to keep it streetable with the good brakes and DR’s, which are the 255/50-16’s.
The track was not hooking the greatest. Krys Efantis and a couple of the other Supra guys smoked the tires pretty good a couple times. I am sure it hooked better Sat & Sun for the race, but I never made it back, oh well!
