So the S3 never fails to put a smile on my face since I put the Porken set up and X pipe in, but I got curious and decided to dyno test, just to see where she is at now.
I can't say she is 100% sorted yet, but she will make the hair on your neck stand up when you get on it.

Unfortunately, I don't have a baseline to compare it to.

It was also pretty damn hot today (86 F) at eight in the morning when I did my runs.
Jon Rhoades is one of the bigger names in performance around here and I used his Dynojet set up for three quick runs.

I was very pleased with the numbers.
Gotta say, she sounded like she meant it up around the redline, I was proud of her...and Ken.







So the 290 rwhp, I'm calling 333 at the crank.
Liked my torque at 300 as well.
I think the A/F looked okay, but Jon noticed my fuel was falling off, up around the red line. I guess I will look into a fuel delivery issue next.

I have a new Bosch FP that I've been sitting on because I got spooked by all the recent QC rumors and just left my old one on after an amp draw test showed it to be in spec.
I guess I will change it out and put a new filter on.

Fuel delivery probably jives with the fact that I had to dial so rich on my (new) MAF, at 710 ohms to get high 14's AFR at 700 rpm (idle jumped, warm but not hot).
Injectors are stock but just serviced and cleaned at Witch Hunter.

Hey here's a looker that was sitting next to me at Jon's shop, sorry these are sideways. Anybody recognize this car?:

I'd expect more, what's after the x?
Also I'm running two 86.5's with pk300 and rebuilt maf s and 4 holes, the both smoke the rears.
I'm not running cats, just resonators and RMB
Edit: where are your cams set at
Thanks,

Dave

Hey Dave, thanks for following.
Cams set at (-2/0). But i could buy into some ignition retard at top end because of the heat.
I didn't do a good job keeping track of air temp sensor. It was a 30 min drive to the shop and I forgot to bring the IR gun.

I also don't think we pushed it redline, the runs were short, mostly because of the question of fuel delivery.

I'm running the same exhaust set up, no cats.
I may look into the four hole injectors, I was hanging back to get more real life feedback. Sound like you are pleased with yours.
Anyway, as good as the numbers were, I'm posting as preliminary because I need to retool a few issues and come out swinging this fall when it's cooler.
I'm having fun with it though, and learning as I go.
Regards.

Dave that shark of yours is a real cream puff.
Great dyno results.

Thanks Matt.

Here's one more of Jon's racer:

These two items suggest your MAF could do with replacement (rebuild).

When they age, they tend towards lean, and also suffer from a reduced voltage range.
