dyno sheets?

I only ask this because this does seem way high espescially with that AOD.

Legendary · Jun 1, 2004

Seems high. You actually seen this dyno sheet or you was told this?

I was at the Dyno while I was having it tuned and a custom Superchips aftermarket chip set up.

So yes that is the Dyno numbers. The Dyno Tech seemed suprise as well but he said he had run across a few others simular to mine with the same mods and the numbers went from 325-350 RWHP

If the port job on your heads and intake is REALLY good and you have 11:1 compression, I could believe that much power through a 5-speed. But not through an AOD. I think that dyno reads high.

Have you been to the track with the car?
As for the dyno #'s I know the operator can give you corrected #'s or actual or SAE #'s
and depending on the day they can range 20 or so hp.
The #'s in my sig are corrected for weather, The uncorrected #'s for that day and run were 396hp. Correceted down, but a previous days session(months before the correction was moving the #'s higher. The correction helps you gauge differences in mods on the same dyno but during different conditions.

Yes the car runs 12.08 @ 112 MPH These are the corrected numbers.

you actually ran the car or was that a gtech rating? the time doesnt quite look like it matches the speed to me. time looks quick, but speed looks low

your dyno numbers seem quite high to me also. yes I am jealous but still they dont look right.

BlownStangGT · Jun 1, 2004

if thats a real 1/4 mile time then your car is making those numbers and that is dayum impresive!

tmoss · Jun 1, 2004

I'd like to see the dyno curve too. With all the porting, you might be making power above 6,000 rpm - nothing you posted so far indicates rpm.

PRO50SC · Jun 1, 2004

Seems way low if you ask me. For what you have listed as mods. I have a stock block, heads and cam. Just a blower and intake and made 332 rwhp.

tmoss · Jun 1, 2004

BigB - your dyno sheet is really hard to read. Looks like the dyno stopped JUST past peak TQ/HP at 5250 rpm. And from the looks of it, who knows if it was peak HP?

The actual time according to the time slip is 12.089 @ 112.764 MPH

344 HP @ 5650 RPM and 381 Torque @ 5100 RPM

381 rwtq is impossible with your motor (VERY difficult with any NA 306). Also, 381 ft-lbs at 5100 rpm would equal 370 hp at 5100 rpm.

Not really.... sometimes auto's have wierd TQ spikes that show up on dynos ...all be it ussually at much lower RPM

Seems high but believeable... some cars are just palin stronger than others & attention to detail is pretty much everythingf

I think you missed my point. 381 ft-lbs at 5100 rpm is 370 hp at 5100 rpm. Mathematical fact. But he says it peaks at 344 at 5650.

Plus, an auto with a 2600-3000 rpm convertor isn't going to cause a torque spike at 5100 rpm.

The numbers just don't add up. It's about time to throw out the flag.

No I didn't miss it just stating something that may or may not be well known.
But yes I totally agree.
