gt500 slayer is comin around

Finally getting this thing to run the numbers more consistent

went to LsFest this weekend and made some good passes


10.42
10.32
10.28

all still on the 20" drag radials.. it went a 1.48 60 !!

Im slowly leaning on it a bit more and more.. I never get to race it in the evening so hopefully when I find some air I can get down in the teens where I want to be on these tires.

Some good track prep and 20's are the ticket.
That converter and meth are starting to pay off. Right on!
Did you spray nitrous down the whole pass?

The problem with my car now is the blower.. The blower on my car is shot. I hurt it trying to find the I.a.t problem. The car only makes 13 pounds of boost now. It made 15-16 when I put it together:(. I had a 35 jet in it for the first few passes of the weekend and it was running what it used to go in motor alone.. I started creeping up fuel and jet sizes every pass on sat.. I let out between the 3-4 shifts.

Baron - just out of curiosity - are you running stock idler pullies or aftermarket? I ask bc I am also losing boost. My shop recently put a gates fleetrunner (green) serpentine belt on a ZR1 and picked up 3lbs of boost. Apparently it is very difficult to detect blower belt slip even on a dyno. Only giveaway was a loss of the 3lbs. Im going to swap belts and go to the larger upper and small lower idlers to see if that helps (more surface area touching on the upper blower pulley)

If you log you car at the track blower slip is clear as day. Your tuner should be able to see it on the dyno as well. It's very easy to detect. Looks at the psi on the dyno sheet. If its all over the place it's probably slipping.

@ Supercharged - Logs have been run. The PSI did NOT bounce during track or dyno runs. No belt slip noise either. I would not have believed the fix but for seeing it.

with the 9.1 and 2.38 aren't you overspinning the blower?
if not, what do you think caused the rotors to go?

@ Baron - If you are running the 2.38 upper, I would really consider running the 100mm upper idler. Much better pulley surface contact. I will let you know what if any difference it makes for me once installed. Im running the 2.55 upper and 9.1 lower.

so far I have not seen any belt slip with the 2.38 and its been on my caddy for 30,000 miles... I don't see any boost loss in the scans, just rotors are shot..and yes, I had a tb screw go through them.. it took a chunk out of the back of one of them and damaged the brick.. I replaced the brick (shout out to pace performance great prices ) and put it back together.. the car makes mid 13s now... at its peak it made 16-16.5 depending on air.... im just going to make it through the season with the current blower and replace it with something this winter..

Trackman has a pretty wicked setup, we are going to our track on the 27th and I'm going to lend him my 20" nitto NT05R's. you might be chasing a lower time than 10.19. I'm going to give his 18" M/T a shot and see if I can crack into the 10's. I've got manual and have run a best of 11.37

So true !!!!! The first time I lined up against trackman I cut a good light, by the 60ft he had already gone around me!! He was pulling away so fast I thought my car was broken lol. I mean I still ran a mid 11. I'd raced a few stock auto ZL1's when my car was stock and the races were close but that was ridiculous!!
