What do you think was the change?

AnimalCrackers · May 12th, 2009, 09:50 AM

So 2 weekends ago I went to a dyno day at Shop 1 who uses a dynojet, the weather was a bit humid, temperatures were great, and it started to drizzle about an hour before I got to do my pulls, car put down 388/344.

Two days ago I go to a dyno day at Shop 2, they also use a dynojet, day was gorgeous, temps stayed pretty low, maybe 5-10 degrees warmer than the previous dyno day, humidity was almost non existant. The car put down 430/368 then 426/381, then they let it sit and cool for about 10 minutes and it ran 447/397.

So my question to you is, what do you think was the 1 thing I did to the car in those 2 weeks to net that change?

Changed a pulley?

TimboStang · May 12th, 2009, 10:45 AM

Either cleaned the air filter or changed the fuel filter. That and loosing the humidity which actually lowers the density altitude.

AnimalCrackers · May 12th, 2009, 11:40 AM

No change was made to the tuning or boost level

kotten148 · May 12th, 2009, 12:59 PM

what the?

BuRnIn_YoUrS · May 12th, 2009, 01:01 PM

the shop?

kotten148 · May 12th, 2009, 01:03 PM

one of the dyno's has to be off

AzSonicSnake · May 12th, 2009, 01:06 PM

temp and air density will make a difference, but dang, thats alot! sounds like a difference in the correction factor used...

BuRnIn_YoUrS · May 12th, 2009, 01:07 PM

where you been sonic?

sounds like the dyno day worked for dyno 2; they've got another customer

2006GTARPD3 · May 12th, 2009, 01:26 PM

AnimalCrackers · May 12th, 2009, 01:56 PM

lol, same correction factors, so far as I can tell there was no difference between the two parameters used on the dyno's. I was dumbfounded as well, I don't know if the shop 2 dyno reads high and shop 1 reads low or what, the ONLY thing I did to the car between the 2 dynos, was to unplug the battery for a couple hours while working on a little paint project on my steeda battery box. I didn't think the adaptive learning would have THAT big of a difference! I know the humidity had a large part in it though, it's noticeable at the track when it's moist out compared to later in the evening with cooler air.

03_StangGuy · May 12th, 2009, 02:05 PM

Well that big a gain should be felt in the butt dyno

onederful100 · May 12th, 2009, 02:13 PM

you paid the guy at dyno 2 an extra $50?

AnimalCrackers · May 12th, 2009, 02:34 PM

Nope, no illicit dealings, the guy in front of me even dyno'd right about where I guessed he would too. I did notice that shop #1's dyno day had a lot of cars that dyno'd a bit lower than I would have guessed them at, not by a lot, but some cars I expected to see hit 400 were only hitting 380-390ish.

and here's the dyno from shop #1:

I'll have to take a digital pic of my new dyno and post it up later

BuRnIn_YoUrS · May 12th, 2009, 02:37 PM

you sucked him off...so he bumped the numbers

This is all conjecture until I see some proof...

You shouldn't be spreading around the trade secrets like this...
