Converter/Kooks shorties track results

[4VFTW]

pretty much identical D/A both passes , but last night there was a 10mph headwind , probably why the back half mph seems weak...will datalog next time I go out.

before

after

I would expect 11.3x-11.4x with drag wheels, free weight reduction and some nice cold air.

Very good gain !!! What was DA on that day. ...your mph seem low for your mod, but maybe it is the DA....

thats a huge gain if the only changes were kooks shorts and converter...

Congrtas Marc! Your car looked and sounded great. Maybe I'll upload the video I took on my phone of 1 of your runs. The converter made a huge difference.

I agree, your car is running good! Wait till we get some nice DA down here and your car is really gonna fly! I think you'll see a 11.3-11.4 for sure!

well those are the changes that are proven to make power I did add

1)Accufab 85mm TB- maybe 2rwhp on a dyno
2)swapped from a JLT to Airaid intake- worth anything?

,but looking back I did also add a aluminum d/s since the last time I raced the car.. lets say that was worth a tenth although its debatable.

there were changes to the tune of course but without back to back passes its impossible to attribute gains to that.

From assumption the shorties added .2 and Ds added .2 . Even with the ds being added that's still a huge gain from those 3 mods. I'm assuming you had a retune after adding all of that?

Congrats man, can't wait to see what it will do on some big and little's.

From the slips all your gains were in the first 1/8. From 1/8 to finish your car is running the same as before the mods. The time it takes to cover the last 1/8 and the mph gained from 1/8 to finish are almost identical to before mods. Not being critical just an observation. Great time, fast car for sure.

Who's tune?

the car definately underperformed on the back half, I would have expected 117+ out of it. not sure if the headwind had anything to do with that. next time I go out if that doesnt improve I will do some logging.

I looked back at all my old slips and my car has always back halved about 24.25mph... I took it to the track after just about every individual mod and have used 3 different tuners over that period.

Those are good times. I think I will be heading to the track today.
