Last year I was able to pull 590 RWHP and 540 TQ on a HOT day on a Mustang dyno. I will be getting the Z back out in a week and installing a methanol injection setup on it, as well as a new metal inlet tube. Here is my basic setup;

383 LT1 (Lunati Sledgehammer Crank, Oliver Billett rods, custom Diamond pistons)
TPIS CNC LT1 AFR 180 heads
Custom Camshaft 244/254 @ .050, .578/.578 lift, 114* LSA
Hand ported intake manifold
Hooker Long Tubes
Hooker Y-Pipe
Borla Cat-Back
Lingenfelter 58mm TB (the gigantic brick one)
60# Injectors
M6 w/Moser 12 bolt and 3.73's
EPP Custom FMIC setup
Stock PCM

It will be tuned on a dynojet, hopefully on a cooler day than before. With my cam being that agressive, it really wanted a lot more timing that we couldn't give it due to the limits running pump gas. I am hoping with the new methanol injection setup (allowing advancement of the timing) and a new inlet tube (for maybe an extra # or two of boost) that I could see 650 RWHP or so.

What is everyone's opinions? Do you think 650 RWHP would be a good guess to the new dyno?

I think you can definitely see 650rwhp... a little more boost and timing with the meth and you'll be there.

 

why dyno on a non load bearing dyno?
i understand it is cool to get high hp numbers, but when you run at the track and the mph doesnt add up, then what?

i thnk mustang numbers are alittle more realistic and a load bearing will help alot in the midrange and "area under the curve"

either way im interested to see what you can make,
650 corrected on a dynojet would be fun!

 

I'm dynoing on a Dynojet this time because thats what my tuner has to tune on. I agree that the Mustang numbers are probably more accurate, however dynojet seems to be the industry standard anymore.

I am pretty much maxed out on boost, unless the metal inlet tube I am installing really gives me boost increase (I am guessing maybe a # or 2 at best). The gains I expect this time around will mostly be due to adding more timing.

 

I'll be looking forward to an updated video! I like that camshaft too!

You won't be disappointed. I have some big plans in the works for the video cam + my Z
