Excuse my ignorance, but what are all the other numbers? Looks like 7xx HP in one column? Surely there's a dynojet or something like that around you? Why use such a fucked up dyno lol

Wow, very impressive.
So I read thru the other thread, could you give a complete run down of your setup? Thats just totally badass, never seen a streetable NA combination less than 400" make that kinda power.

Wow outstanding results, congratulations!
What was changed between 590-630?
What do you estimate drivetrain losses at?
Better trap 135+ LOL!

Thanks navy!

The biggest thing was timing. It liked more. On my setup I'll be sitting around 27*

My drivetrain loss will be low. Lower than most.

I actually went to this dyno because it's locally known as accurate/low so people couldn't cry foul. I was prepared to receive "low" results because in the end dyno tuning are just numbers and the before and after numbers are what really counts. Myself and the dyno owner were floored TBH.

I wish more people could realize this basic truth! It's about the contrast....

Really that's it... I gained around 40 rwhp with timing and you just cant feel that in this car on the street. You open it up and it's squirrelly regardless.

Whether it's 600 rwhp or 640.. doesn't really matter. I'm happy
