shots from the garage...
Tow three hours to make three hits.... because that's what we do! Hit a test and tune yesterday at Fontana for the first time. I had visited the facility a few weeks ago to see some friends and watch the NMCA action so I had scoped out the facility beforehand. The sayings of "uphill track in a parking lot" hold true :). The shift rpm timer and air shift worked flawlessly, and I was also very pleased that my newly remodeled transmission only took 200 rpm to make the shift.... it was at 600 on the 1-2 and 2-300 on the 2-3 so now it's as quick as I'd expect. While it's true about anyone can "build" a 727, there is an art to getting the proper shift timing and Dave at Pro Trans didn't disappoint. Some of the rpm "dip" at the launch was eliminated as I had sent my converter back to Lenny at Ultimate with updated build data and recordings from the Racepak it now flashes at 6300-6400. Only thing I do question now is that the stall speed has increased, do I need to make sure that the shift points are high enough not to drop below that threshold. On my 1-2 shift that takes place at 7K, it will drop to 6200 so I'll have to research that. Bummer deal is that I did have a leak coming out of the bellhousing so most likely we'll be pulling the trans again to investigate. I'm glad the two piece floor and lack of torsion bars makes this task much easier.
The three passes..... the first one discovered during the wiring debacle last week the line lock didn't get hooked up correctly so we did a half azzed burnout and was rewarded with a crap 1.39 60ft time. ran 9.67 @ 140.8.... not impressed. 2565 DA... I ran faster in Vegas at over 5300 DA in 96 degree heat. Mph was "ok" so I'm not fearing a mechanical issue, but I was expecting a little more. Second pass line lock operational so we got a decent burnout, but car got squirrely at the hit and I let out of it after the 1-2 shift. Third pass it was 2:00 pm and the wind had graced us with it's presents. 13mph gust 23 pretty much a headwind. Another crap 1.35 60 and ran a 9.64 @ 138.2. Fontana has a "sound wall" that runs along the track and with the wind when you get to the traps lots of things happen to your car..... it was an interesting experience for sure and at that point we figured we'd learned about all we needed for now. I'm hoping to get to a more familiar track and get some comparative data to see if the converter change is hurting me or what. Still crossing the stripe at 7k so I need to get the 4.30 out and .56's in. Probably need 88's, but I have the 4.56 so we'll give it a try.
