Off to the dyno this morning, same one that I've made a couple hundred pulls on my last 5 cars. I don't know what it will make but guessing north of 650. Mike has made changes since the 10.34 pass to fix a few things after some street logs. Still running the same timing which is about 24.5 to 25, the logs looked really good and the car is just flat out fast on the street just a street tire is not an option anymore. We are going to try a smaller pulley after a couple pulls with the 105 and we were about 8.5 to 8.5 psi. The 98 I have would be just about 1.2 to 1.5 psi of boost which would put us just about 10.0 to 10.2 psi which should be pretty safe. I have a 10 rib pulley system except for the top so once we find out which is best I'll have a 10 rib made by either Mike or Griptech. Griptech has a 100mm in stock so maybe that will be the one that would be just right for my setup. I'll will post up some numbers later this morning and graphs this afternoon.
105 upper (Magnuson)
9.25 lower (toohighpsi)
Port injection and controller (toohighpsi)
2300 Maggie w/Corvette lid, she whines pretty loud(superchargersonline)
10 rib pulley/tensioner (toohighpsi)
103 snout (Nickey Perf)
RotoFab (not a big gulp)
95mm TB (stock)
JMS V2 Voltage Booster (MartinLE)
Stock Lt1 with 4400 miles, stock fuel system, locked tranny, everything else is just like it came from the factory. Later

Good luck, looking forward to your results! Although I can’t help but notice you’re already looking at a smaller pulley LOL

Griptec pulleys rock and they usually have them in stock. Even if you want a custom size, it’s not a long wait. I just ordered a custom size and it was under a week wait time.

Griptec is the best hands down. Their customer service is second to none!!!

Good luck i am looking forward to your results. Thanks for keeping us posted.

First pull it made 632/550, kpa was 156 or about 8.2 lbs of boost. However the boost gauge was 9.5 at the blower.
NA 11.64@120

Blower 105 mm pulley 10.34@135 at LS Fest.

w98 mm pulley, ET/MPH to be determined in October at my next outing.

I think those are great numbers maybe not as much as u were hopping. Am I seeing afr about 13.0 at wide open?

[SATINSTEEL1LE]

Awesome numbers. I just got my maggie 2650 for my stone stock ZL1. I might need to bend your ear on a few things when I get mine installed. For instance do I really need to upgrade the spark plugs or can I run this kit on my completely stock car for now until I turn it up? Car is a 21 ZL1 with 3600 miles.

Nice numbers BTW.

Fantastic numbers for the mods, a perfect SBE mild blower build. Get some drag radials man, spinning at 80 mph ain't fun.

[laynlo15]

I run drag radials on the street already. This car will never see a street tire on the rear. We made a couple more pulls that were almost identical to the 677

[laynlo15]

Done for the day. Not going to make anymore power. Going to get a 100 mm griptech in a 10 rib and I've already located a belt so that will a little less boost but be a great pulley all around, might lose a few hp but that's ok also.

[Kerry]

Were u using the nitto 11s and what size?

[ZO6Ted]

Wow just wow! You sure know how to get things done! Do you know your raceweight? Just curious how accurate these online hp calcs are.

Right at the peak, we fixed that and the highest is right at 12.79. Had a little knock and fixed that although Mike thinks it was not real knock. Did a couple pulls after the 677, one was 676 and the other was 675 but we didn't really cool down after the corrections and engine temps were higher then the other pulls. Yes they are the Nitto 555r2s which is the latest version of the 555. They are 305 35 20s
