12.44 @ 108.2 I guess I would be behind Beech cause he was quicker by .005

Nope...you'd be in front of Beech because your mph is faster. :) I only go out two digits on ET. Edited the previous post to put your time in.


I was so stupid to put those 30% injectors in my truck. Someone please smack me upside the head before I make a dumb decision like that again.

See if you can get someone to send you their stock ones and some cash. You come back to this I may start playing with my LMM. ;)

What are you guys seeing for 60fts with street tires?
Also what do you run for air pressure?

I haven't tried messing with the pressures yet, been running 35 & 30 since last year.

I'm very confident i can hit that 11.99 in Mission in June lol, i got a LBZ regulator ready to go in and the truck is getting stripped from every pound possible this winter haha.

Intercoolers are allowed right? I'm probably gonna get rid of the stock one and i might also go with a reman CP3, probably stick with the lb7 one. I think mine is getting tired after more than 200.000 miles:roflmao:

I ran 12.37 @ 107.8 MPH in Topeka this weekend, that's higher MPH than usual in my truck for that ET. I got rid of the stock fan and installed 2 taurus fans. Only ran one fan during my runs.

Sheesh....people got on me for running those dumb injectors, but you've taken it a bit farther than that. I doubt the intercooler will be ok (my opinion), but I cant think if anyone else had anything but oem. I also dont think anyone has elec fans either. Shoot...yours is almost a pure racetruck now...iirc even Buck was driving his around when he went 12.18.

I still run mine around every once in a while, it's fun cruisin around in Calgary haha it's easy to get around traffic.

Ya if intercooler is a no no then i'm not putting one on til i've reached my goal.

And the fans shouldnt be a problem, i dont even think they increased my times much, if any at all. i ran 12.2's at sealevel all day long, i'm running 12.5's at 2200feet all day long, and ran 12.37 and 12.4's in Topeka at 1000feet, so that's right in the middle and so are the times.

Dudgy good to meet ya at Topeka. What was your race weight? I drove up and went to tech with out anything taken out of truck and weighed in at 7800. Went back after taking everything out and was 6745. I still have full seats, interior just minus tailgate and race rims and tires.

Tom, everybody in front of you has electric fans & I can think of a couple with intercoolers
& so it continues
