4.8 10.25@133
took the truck last night to edinburg race track first run noticed transmission acting up didn't want to shift to 2nd so had to let off and let her shift and hit it again managed a 13.00 lol tried it again shifting same thing managed an 11.2.... we were going to stop for the night but deciede to see if we could get it into the 10s.... messing around letting off before 2nd.... went again with same boost 13psi went 10.9x... again same boost 10.75..... picked up the boost to 16 psi went 10.45 with a 1.46 60ft...... last run on 18psi 10.25@133.2.... set up consists of a 4.8 with 243 heads, holley mid ram intake, spt cam, 80e, circle d converter, 83mm bullseye turbo double batmowheel, and full leather interior no weight reduction..... this was made possible by the spt crew and a great turbo was launching hard and displacing the power great .....

1/8 mile was 6.57@107.2 hopefully we can get the 9 out of her..... this was lauching at 4 psi but these turbos seem to like to displace the power smooth and fast let me try and upload vids or u can see it on my fb Mario ladelonce

yea it was pretty difficult with the transmission not going into 2nd at wot....but did let off and went back in it...... I don't have any logs since I didn't think it would run wat it did...... turbo played a big roll on this since it has all options to spool a lot quicker ... now I think this is going to be to small for my 346 !
