Found this today whilst cruising for ROM tunes.

So I pasted them over each other. These were all tuned by JK Tuning using Nismotronic, atleast from what I gathered.

Pretty impressed with the little T25... :2f2f:

I dont think anybody is making 275 rwhp with a T-25 at 13psi

most of them have trouble making it to 250rwhp at any boost
You have to be carefull when looking at any dyno graphs, especially from unfamiliar dynometers. As much as I hate to say it, ye olde dynojet is the tried standard I prefer (When it comes to comparisons). If we are not doing comparisons, then it doesn't make any difference because +1 is still +1 on a back-to-back run.

^^^ There is a good chance those T25 numbers are on E85, at which point, the numbers seem "hiked" but almost feasable.

The FWD boys with SRs have been maxing out T25 turbos for years with E85, so it has been done!

Yea, but they appear to be on the same dyno. Don't know how much calibration is needed from run to run or maybe it's dialed in high from the start... either way interesting with the S15 and 2871

It also appears to be a hub dyno, or whatever they're called. So maybe that helps augment the numbers a little, but again I think it seemed high too.

Just thought it was interesting "compare-o" and whipped it up quick at work while I was bored as shit...

Actually the car who is dynoed is a local to my area and the guy who runs thee shop (John Kerr, hence "JK"tuning) is the same guy who's ECU I am running

Nismotronic!! :). Been to his place before and he is VERY knowledgable!
