Update....
Well, I upped to a true 75 (I.E. @ the tires), the car now has a 6131 on it, I stepped the gear down a bit (now running 3.20's), did the typical drum brake modifications, and did some other minor odds and ends...
Car ran a 13.5 in true street trim, low boost, pump gas, easy launch, shakedown pass....
Next pass, boost was @ 19.5 w/o NO2 and about 22.5 on the kit. Cut a 1.58 short time on the same drag radials I DD, and ran a 12.0 @112.....My converter hanger gave out on me, the exhaust started trying to beat through the floorboard, and I thought my 19.9* of KR was coming from the NO2 or the tune.....the exhaust was just hitting the bad, regardless, I was off the juice about 400' out. Still looking for 11's...
3rd pass, it didn't hook quite as well but still cut a low 1.7, and either I blew out the spark or the extreme amount of KR (again, from the dang exhaust) caused it to cut out, had a mild nitrous backfire (wasn't the first, won't be the last.....it didn't hurt anything) and got on the brakes about the 1000' mark and ran a 12.50@81....
Once I get the new exhaust hanger on, I'm gonna toss some new plugs in there, gap them down a bit more, and try it again....I'm hoping for some mid 11's at the least.
Again, just an update
