Finally got on the dyno!

[slowgsr]

This is my first time doing any real tuning with my car on the dyno. We stopped as it got late (12:30am), and my car is loud.

Boost is 27psi right across, and timing is 13.5-14.5 deg. AFR is 11.2-11.4 all around very conservative. I was using C16. I picked up 0 knock on any run. I will dial it in at the track.

It made 579hp.

Im fairly happy, Im not a tuner, but I do all my own tuning. As I said this was the first time I've had it on the dyno to do tuning, so I didn't want to get cocky and hurt the engine. Just taking small steps, learning as I go. Its lots of fun!

EDIT: Looking at the log, I actually see 26.5lbs of boost. On 24.5lbs I made 530, once the turbo started to work in its range, a bit of boost makes a lot more power. It will be fun to see how it reacts once I turn it up more

Nice! At what rpm do you hit 27psi?

Wow! You must be one happy camper!

 

[Woot]

your listed as driving a awd yet to me it looks like your only running fwd on the dyno?.. is that the case?

That mic is terrible. I thought the whole time the car was breaking up

 

[Woot]

the rear wheels dont even look to be on the rollers?

Welded center differential.

Not bad, look forward to seeing more pulls.

 

[Woot]

alright thanks captain obvious, please tell us all again that its a welded center diff... DUH!... I was just asking if he DID dyno in fwd or what?

 

[slowgsr]

guys, I have awesome access to a fwd dynojet that I can use whenever I want. I have a hoist in my garage, or at the dyno shop that I can use to pull the tcase/driveshaft, it takes 20min. I have a welded center diff so I can dyno/drive like this.

I went to the track on this power level, and did ONE shakedown pass. I had my street tires on, and didn't leave the line hard. Heres how the slip looks.

60 - 2.049
330 - 4.945
1/8 - 7.234
MPH - 110.24
1000 - 9.206
1/4 - 10.852
MPH - 141.13

So, at 579hp the car went 141mph. I checked the log from the run, and boost was the same as it seen on the dyno to within 0.5psi. It holds boost very well. This is a full weight 1g as well, It has a full 10pt cage, FULL interior, as well as a a2w IC setup with a 40L watertank.

I was fairly happy, I can't wait to get my QTP's on (that alone will knock 50lbs of rotation weight off from a rim/tire switch), and run some more boost!

Overall the car is running very awesome.
