Posting this up for informational reasons. I beleive outside temp was around 50 degrees F. AFR was too low to be read, and my car was and still is in dire need of a tune. As stated in the title, my only mods were an MBC set to what I thought was 23 (hit 24 on the dyno) and a spectre air filter.

nice numbers for a mbc and cone filter. Must have leaned it out a little.

So, 279 lb ft of torque at 3700 RPM and looks to be 263 HP peak at around 6000 RPM. Any idea why they wrote in your HP at 5252 RPM (241 HP)? Not bad for just an air filter and boost controler.

if Ive read it right.. that was peak 241HP and 279 torque.

do you know if you maintained peak boost all the way through?

Peak HP is at around 6000 RPM and was aprox 263 HP. For some reason they wrote the HP/torque at the cross over point where HP and torque are equal (241) on the graph... I asked the OP about this but he has not responded.

If you look at the second graph you will see that peak boost was 24 psi at 3250 RPM dropping to 16.5 psi at 7,000 RPM.

looks like the TQ curve could be staying just above the HP curve, or he has incorrect numbers.

HP = (torque x RPM) / 5252

HP is always less than torque below 5252
HP is always greater than torque above 5252

The HP and torque lines cross at 5252 with HP continuing on up to a peak of about 263 HP at around 6000 RPM on this graph. Actually using the two data points (263 HP and 225 lb/ft of torque) in the formula and solving for RPM you come up with 6139 RPM for the peak power.

yep, i look closer now, no doubt.

and wow, i have quite a bit more mods and only made like 15 more whp and a littel less tq but for about 1k rpm longer. plus it was a 100degree day but i think its time for a tune!

Unless your car was dynoed on the same dyno, there is little use in comparing from one to another, so don't sweat the fact that you only have 15 more wheel HP.... what was your gain over baseline stock HP? If you didn't get a baseline, what was your HP as compared to the "average" stock EVO X baseline on that dyno?

went from 243 to 275, so not to bad.

Sorry to have never responded to my own thread. Regarding the weather, it was around 50-60 degrees F. And the reason they wrote 241 on my graph is because the shop insisted I screwed my car up because the AFR was so rich.

And to reply to meat_EVO, the weather here really helps keep things cool! Wish I could have grabbed some pics of my car on the dyno.
