What is "Ceng" is that Crank power?
Your graph doesn't show your SAE TQ to the wheels.

Do you have an aftermarket intake?

jumper5836

Yes, Crank

SAEPwr is HP to the wheel

Most dyno's can't measure crank hp. but these Superflow dynos do.

A have a stock intake. I have a evo but I removed the evo intake after I heard people saying it lost them hp. Plus in is an inferoir system and the stock keeps the air being taken in cleaner.

Ok, I was shocked about Crank results but then I relized it wasn't a "dyno jet" to which I'm accustomed.

As far as the Evo, I've had no problem with mine. My throttle body is spotless and I certainly haven't lost HP. It is hard to keep the proper airflow at a dyno event for our cars.

Oh yeah, tell them to send you the file with your SAE Torque.

jumper5836

I think the max torque is the yellow line. 258
[edit ya torque to the wheel is missing, I'll have to wait to see what I get in the electronic copy]

This setup has proper air flow, very awesome setup. Video

zman2002 C4S

Only 13 more crank HP for a modded 3.6 over a stock 3.4? That's surprising.

jumper5836

Yes and the surprise was the stock 997.1 vs the 997.1 S

I think maybe with all my mods that I lost HP and I would have fared better vs the 3.4 as just stock.

I feel the same, but it sounds good and my car was the Loudest there

washington dc porsche

OH Sh*t! That's state of the art. I've probably been to 4 or 5 Dyno shops in the DC area and hosted 2 and have never seen anything like that!

I think you loose alot of backpressure with all of the exhaust mods however I'm interested in seeing the tq curve to the wheels to compare to my dyno to be sure. I don't see yellow, I see orange and thought that was crank tq?

jumper5836

Honestly when we were driving home and after you waved bye. My window was partly down and when you got on it, it scared the crap out of me.
Very loud. I imagine you'll end up scaring an old person off the road one day.

Just the Dyno Room itself is $700,000 Plus... There is huge Impeller under the Dyno to Desipate the Heat from the Car and Dyno so there is no Heat Soak during the Run. The Air in the Room is Exchanged every 5.7 Seconds and Fans can Simulate 120kmph Wind. Apprently this is the Only One Of Kind in North America and the Dyno Manfucaturer said this is only kind of Dyno Facility in the World owned by a Private Small Shop

Already done Women, Kids and old People all Checked off :P

Do you have a dyno baseline before you did all your mods?

I know some of these mods don't necessarily create peak HP but I'd be curious as to which ones are more effective(or less) at broadening the power curve.

I think this fact along with improved throttle response should be able to improve track times where it would be more quantifiable than just a HP number.
