here are a few standard things i like with the dyno.

Pick a place. And dyno your car there every time. some dynos vary up to 10%.. so a mod that might gain you 20-30 hp might show NO effect at all moving dyno to dyno.
Stick to SAE.. Some shops put the output in STD to boost number and "make the customer fell happier"..

here is an example.. with headers/CAI/tune my car made 431/421 Uncorrected.. SAE was 435/425 and STD was 445/434... 9 rwhp isnt really that much of a difference.. but on that day the 2 correction factors were CLOSE since as you can see the uncorrected was almost the same as SAE.

with the first blower and stock motor.. Uncorrected was 760/645.. SAE was 779/662 and STD was 794/675.

Another thing that i like to do is get the dyno files. bring a little flash drive with and have them copy the files over for you. I have almost every single dyno i have done on my car and it is usefull when comparing one mod to another.


again.... i have been acused of being a bench racer and a sandbagger, but clearly my tools are working for me :)

i like to compare the gearing to the powerband on the dyno to figure out where i need to shift.. i SUCK at the driving.. so i need to make sure i have as much information to help my decision on when to shift as possible lol

A fuel pressure gauge, a timing light and a screwdriver is how it was done. lol

Haha. That too. I remember tuning my very first blower car. Rolling down the road with a buddy holding a boost gauge and a fuel pressure gauge in his hands with hoses running from under the hood, through the window while he watched them while I made pulls going down the road. I'd pull over, make adjustments to the timing and regulator and do more pulls until it stopped pickin up power. lol

Most of these young kids now don't know how to do squat to their own cars anymore that doesn't involve plastidip or switching a plastic bodypiece. lol.

I'd like to learn how. My dad misses those days. We have tried multiple times to pick up a small project car, but with the distance between both of us right now, working on it alone for him wouldn't be as fun. He'd still enjoy it, but he knows I'd like to learn what he knew.

He could change the clutch in his old '69 Apache Chevy in about 45 mins while parked over a ditch. Haha
