Dyno disappointment?
#21
Rip, don't let low dyno numbers do a head trip on you. You have a nice ride, Vert99 is right, when you get in and go, your butt dyno makes you happier than a graph. I was down mine only hit 267rwp (hoped for 275) at Brenspeed's shop, but the car is a blast to drive.

Wrote an interesting post about this issue, search under my screename for the word "factory freak" and it should come up. The problem has to do with the way Ford chevy etc build their engines as opposed to how high end engines are built.

I email'd the hp/tq chart to brenspeed. There was no wideband hooked up so no AFR to send this time. I guess if I bother to dyno the car again I'll see if that's something we can do.
I'll be curious to see what they have to say about this.

IMHO It looks like an anomaly, that lasts a fraction of a second, and should not be counted in the overall RWHP numbers.

So only 8rwhp/4rwtq going to 20x10's eh? That's kinda what I thought. With the 20's what was your overall diameter? With the 295/45/R18 I'm at 28.5".
I've been considering emailing brenspeed about this as well and I might do that next week just to see what they have to say about it.
Especially if brenspeed pushes for it I might spend the $100 and schedule a dyno next week with stock tires on the car.

I forgot the exact weight difference breakdown for front/rear, but between the sets of four wheels/tires the total was 89lbs heavier for the 20s.
I would be interested in seeing the A/F too, especially with that "spike" on both graphs happening

I have an 07 manual with 4.10's, pullies, C&L CAI and a dyno tune. I'm running 295/45 rears. My #'s are 300 rwhp and 302 tq.
Those #'s seem low.
Take it to the track and see what it does. The track never lies. Mine dyno'd stock at 265 rwhp.

I'm sure in your case a dyno tune helped quite a bit. Both Mishri and I are using canned tunes. We don't really have much choice as far as that goes.
300rwhp for nothing but an intake/tune and a set of pulleys is really, really good.
