It's been a while. My Neil Chance was behaving exactley like another member on the board here as both of us ordered ours about the same time. I believe they were built the same. I could not build ANY BOOST above 2.2 psi and that was at about 3200. The convertor was just too tight. My invoice date was 6/21/02 just for timing. I tried jockying the shims per Chance's recommendation so out she came and back in for a mere 50 rpm, but no boost above 2.2 psi. I cannot even race the car in this condition. I pull the convertor out, send it back to Chance for a new pump and get it back in about 1 week, which is cool. I go to install it, and it doesn't fit. It's too long. WTF??? I send it back to Chance and get it back in another week and guess what? IT STILL DOESN'T FIT!!!! the measurement is just under 6.5". I need 6.187. Chance buys the convertor back from me and I lost 2 monthes of time. All I can say is they gave my money back with no hassle. For $1899.00 should I have had this trouble?
I bought a Precision Vigilante 9.5" from Bruce Aldred. I made it out to the M7 event. Without getting into the details of every run, my best time was 10.28 and my best MPH of the day was 134.5. I picked up a solid 6 MPH in the quarter and run 30 MPH faster from the 1/8 to the end of the 1/4. I picked up 2 MPH in the 1/8. I went from my usual launch boost of 13 down to 7 for the 10.28. My 60' was a high 1.4. It was like driving another car. My best MPH with the old convertor was running 30 PSI. I was only running 28 PSI yesterday. I can't believe how much power I was loosing through the old convertor. I think my target lauch boost will be around 9 and that's all. There is tons of torque right there at lauch that was never there before. I lost a lot of time in the torque convertor fiasco, but I highley recommend going through a vendor for your convertors, as they know WHO to deal with and what to say. For $650.00, 6 MPH was pretty cheap.
