That's what, 280 SAE? Not bad, one of the higher numbers I've seen.

Ahh. I hear a lot of good things about Kaufman's but that's a little far.

Nice numbers... I wonder how much the AC delete earned...

1 or 2 at the most. the AC pulley is free spinning when not in use.

Why is it significantly lower in your other post that actually shows a graph? Your post where you claim to run the 13.2. Powershots put up his dynograph. Large variances. His=269rwhp/283rwtq

thats what 14whp and 24wtq?

In Maryland, Heffner's Performance has a dyno. They specialize in Vipers, but they used to be big time Mustang tuners, so they know what they're doing. www.heffnersperformance.com

Well Einstein, since you are all knowing, I'm sure you already know the answer to this.

However, I will help if not. You are talking about a different dyno, on a different car, on a different day. Your standard Dynojet, or any regular dyno shop, has variences from dyno to dyno. If you choose not to believe me, take your vehicle to 2 different dynos on the same day............... and I would bet you big money you will get two different numbers.

The only dyno graphs that can be directly compared are those on the same day, at the same dyno. After that, it is just a guideline to help you see the effectiveness of your mods.

Now, manufacturers dynos are a totally different story. They also cost about 10X what your local Dynojet costs.

If I'm not mistaken, the AC automatically shuts completely off when WOT, so the hp gain would be near 0 at WOT.
