There is alot wiser men than me here but I thought for a few years I could run the D5 PTS w a TE 44 but I had a front mount and a PTE 85 housing, That didnt work. I finally bought a Vigilante 0 pump 5 disc and its like a new car. Stall is around 3000. I can build boost at will on the T brake and I am racing for the first time in the morning here at Norwalk with it and hope this is the ticket. I could only get 2.0 60 foots before but the top end was awesome. 12.30s @117 really sucked.
