AI200cc stock bottom end dyno results, 429rwhp with a miss
First a rundown of the car
97 Z28, 6-speed with 3.73's
stock 100k mile bottom end
stock waterpump
unported intake manifold
AI 200cc heads
AI custom cam < 230 degrees
Jethot longtubes
3" true duals with spiral flow mufflers
lingenfelter CAI
Descreened stock MAF
58mm tb
I also did 438 and 439rwhp on 2 runs but they said that was caused by a spike from the miss up top.
I'm also getting a miss you can see on the graph. My tuner and the shop thinks the stock ignition system can't handle the cylinder pressure since it's happening at peak torque. It also runs perfectly smooth at part throttle, and the opti has an msd cap/rotor with less than 1000 miles on it that looks brand new inside. I wouldn't be supprised if I picked up some power/torque with the ignition issue sorted out. I also had the highest dynoing stock bottom end LT1 they have seen
Anyway here is the graph...
Hopefully I'll have the ignition issue sorted out when the track opens up next year.
:edit: video added. I'm guessing my shortlbock has seen better days with all the oil smoke

Like I said on tech...that thing should be a blast to drive!!! I only make 375 rwhp and run the numbers in my sig...Your stuff should freakin' fly!!! Just toss a few $$$ away for a new/rebuilt short block...

Awesome numbers Rob, wish I would have gotten to dyno my car with the 10 bolt, probably would have been 410-420.
I dynoed 375 through my 12-bolt and 6-speed, but it didnt run as fast as your car. You dynoing the same as me with more drivetrain loss just proves that your motor is making more power, hence the better times. Plus you probably have stupid high torque numbers through the auto and gears.
