I am running a glide with a 4500 converter. I dynoed this past weekend and my numbers were a little low NA and with a 250 shot NOS. Anyone have any idea how far off it might be from a 6 speed car?

The car runs great 1/4 mile but dyno numbers seemed low.
Just wondering what you guys think .

I have a glide also and a bigger stall than you have. I just calculated a 25% loss thru the glide and 15% thru the 6 speed. That way if it is less, then I wouldn't be disappointed.

glides and stalls eat dyno numbers alive! that 25% sounds about right, good thing the ETs usually say otherwise

Yeah my 370 with 13-1 compression and a 250 shot on the dyno was very diappointing. Track times will tell.

When I had my 6 speed, I was at 18lbs. of boost and made 920rwhp. When i switched to the glide it took 20-21lbs of boost to get to the 920rwhp.
If you do the math it's about right. 10% difference would be 92-100rwhp and I am making appx. 33-35rwhp per pound of boost.

Nobody could really give you the right % your off.A car like that is a track car and just use the dyno as a tuning tool.

Our race cars run the glide and a few bury the 1200hp dyno but it takes alot of boost.
