Dyno Results

DerekStangGT · Apr 23, 2005

first of all, it was on a mustang dyno i was thinking it was a dyno jet, but oh well, at least im not a dyno virgin anymore. anyway, today there was a mustang dyno day and the cost was only $20 for 3 pulls. i was on standby, so i get an email last week saying i got the first spot on saturday at 8:00am. so i get there and only EJ was there moving around cars. then the owner shows up and says "how'd you like a free dyno for helping me push some cars around?" so i helped move two stangs and got 3 free pulls w/ A/F readings im disapointed w/ the results since the mustang dyno takes weight into consideration. the owner also said my 4.10s sapped a lot of power too. he said my A/F ratio was perfect. right at 12.9-13.0. anyway, on with the pics!

Great to have your a/f at 13.0:1. I dunno but some people can do a rough conversion from the Mustang Dyno to DynoJet. I'm going to move this to Tech in case someone knows.

I thought it was 20% difference from Mustang Dyno to DynoJet but that can't be right as it would put you at 260rwhp DynoJet with only o/r, dumps, timing.

$20 is ****ing awesome. I paid $50 for 2 pulls with a/f on dyno day on a DynoJet.

i calculated a 10% difference and got like 247 rwhp. even that sounds a little high. yeah, $20 was a good deal, but i didnt even have to pay that!!

The guy i raced put down 234/270 on that same dyno (ccs tuning) here in austin after it was custom dyno tuned (231 before). He turned a 13.6 @ 103 down at SAR before the tune. My friends 02 SS put down 286RWHP on the dyno. I want to run on a dyno jet though, BUT I may take it too him.That weight seem sort of high, and I know he doesnt have a weighing station around there.

286 is low for a ls1 stick... was he a auto... if he was a stick then this dyno reads a little low...

is a mustang dyno that bad in which they overcompensated for friction? i alsways thought its better than a dyno jet, putting a load on the car instead of just winding up the engine...i wouldnt expect ur car to be THAT powerful since u only have a midpipe c/b and timing adjusted..your car could also just have had a low stock HP number to begin with just like some other cars on here..

Here is their web site, www.ccstuning.com and check out their dyno results section. Some of the 350HP GTOs put down LOW #s. This dyno loads for weight, and wind resistance, and probably a few other factors. The SS is a 6spd with nothing more than a custom tune (actually on 87 octain LOL, but we wont go there) but was run with 93 mix and the ecu kept bumping timing each run.Went fron 267 to 286 in 3 pulls, then they shut it down...probably still had some more left init. Funny thing is that before gears and chip mine pulled just about the same as his (he drove it). I need to race him. He also had a bout 75K when he tested it.

If they use the dyno incorrectly (weight, gearing, other stuff?) then yes, it's bad because it gives incorrect numbers

Putting mine on the dyno tomorrow. 40 bucks for 5 pulls.
