Default T Rex, PRC LS6, Fast 85 Graph, XS LT's 462 RWHP

I posted the numbers when I had this done but never did get the graph up. The blue line is NA and the red line was with what I thought was a 100 shot.

243/249 613/620 110+2 dot to dot Trex

42# Greentops
Powerbond Pulley
Fast 78 hogged out to an 85mm, (unported for now)

This is an M6, through a 4.10 9 inch with a locker with an open cutout

nice numbers on motor. Why the low numbers on a 100 shot?

I don't know... I pulled the line off thinking it might have been a restriction. Cleaned it out and took it to the track and ruined my tranny. Going to have to wait until next year to get it all figured out.

Also posted a thread in the Nitrous section a while back to see if anyone had any ideas.

Nice Chuck! Hope you can get it out early spring. I will be heading to Byron on Sat and hope all goes well. Did you check the jets to be sure they were correct?

Oh, and I think your specs are off on that T-Rex. I think it is 242/248 608/612 110+4. Mine speced out 243/249 609/614 I think.

Oops, fixed. My did come out with the 613/620. Did check the jets. I noticed that the purge was a little week so I pulled the line off the noid and cracked the bottle to see if that might clear it. Purge looks better now, who knows...

Wish I was going to Byron this weekend. I've been so bored with the car sitting up on jacks and the tranny in pieces. I almost bought an entire new trans just so that I could get out one more time.

PM me if you get some new times

My car picked up over 100hp and 100 rwtq with a 100 wet shot. Could it have to much or not enough timing?

Look at your a/f ratio on the nitrous. You are running really rich, which is giving you lower power numbers. Is it a wet kit? If so, run a smaller fuel jet to lean it up.

Thanks Ryan. That's what I was thinking and that's why I posted the graph. I wanted to see if anyone else thought that, since I'm a nitrous newby. I may have had a restriction in the line but won't be able to check until next year when the car is back together.
