Dyno Day - March 14, 2009

[gbauer]

I got 216...

If it had been a Mustang dyno, it would have been 10,000 hp though...

[DoNDoN]

I got 317.

Ed was a great guy to work with and I think I will definitely use him again. He took his time to do each dyno and you can see he really loves to work on cars. I hope we set up more dyno days at York Automotive.

I got a real good feeling for him and the shop. I wouldn't mind the trip also to use them.

[Car54]

More numbers??? Post 'em up!

[Scany]

I believe my 325 got 147.

+1 on York Automotive. Ed was great! I will use that shop more.

291... with pig rich AFR's. I was a bit disapointed... Just remember that Ed's DynoDynamics will read lower, (a lot lower) than a DynoJet... Interesting, it reads about the same as the DynaPac I used at Agile...

Once I get to a scanner today, I'll get all the graphs up on the site.

222/222 here.

This dyno is a harsh one. Estimate drive train losses @ 20%.

So by adjusting for 20% losses, I hit 270 at the crank and you hit 277-ish...


...but if I wasn't misfiring....

What was your TQ number?

[Scany]

After double checking the numbers I stand corrected at 152 @ 5800rpm

Here's the more specific numbers for my car:

222 RWHP @ 5800 RPM
222 RWTQ @ 4400 RPM

George's car:

217 RWHP @ 6100
217 RWTQ @ 4200

It's interesting that his car hits max torque 200 RPM lower and acheives max horsepower 300 RPM higher.

Without the misfire, the torque number wouldn't have changed, however, looking at the graph, it's pretty obvious that you would have got around 2 horses more peaking at 6300 or 6400 RPM.

Post up your a/f ratios. I forgot to look at the difference there. Mine was basically staying around 14.2. What was yours around? 13-ish? Per Ed, 13.2 is ideal and mine was slightly rich. Dinan is a conservative tune. That's the real difference between our cars. The Shark might just be worth a few hp more...

[mcoupemindy]

That's the real difference between our cars.

Power wise, yes. Everything else, no. LOL.

I'll still beat you because I weigh less....
