***** OFFICIAL DYNO RESULTS *****



Here's a link to a larger uncompressed version:

I think there's more power with some more fuel up top eh? A little lean!

Plus... I think the 41mm chokes are too small. I'm going to go up a notch.

I think I can get 300RWHP.


So it's time to go through the results and see who won!

And....

Just for fun:

Here's last the dyno chart comparing the 3.0L that was in the car, with the 3.6 that's in the car now. Both dyno runs were done on the exact same dyno at the same shop!

(the 3.0L dyno run was used for the last "guess the HP contest..." last year)

I was only low by about 4.9hp low on my guess. Not bad for the first one to guess!!

Cheers

My "unofficial" really quick scan says that Tinker is closest, camgrinder beat me by .4 hp, I think i came in 4th or 5th and I missed by 2.1143 hp.
It was very close.

[Shuie]

Nice pull! congrats!

[snowman]

Looks like the guy that stayed up all night making the graph came pretty darn close at 286.

[Dean924s]

Never underestimate the law of averages.. .. and it only took 10 min or so. Just plugged it in to Excel.

[camgrinder]

Nice job! I think I get 4th place?

Did you push in the clutch at the end of the run?

[Wrecked944]

OMG! That torque curve is so beautiluf it makes me want to weep with joy! And with carbs on top, it must give you truly supernatural throttle response. Thanks for sharing!

[911teo]

Awesome! I was "shy" by 1.44hp... Tinker beat me by .54hp... talk abt close...

Great results.... assuming 15% drive-train loss your engine is putting out 340hp... That's nearly 95hp/litre... Incredible results for a street car! And that torque curve.... WOW!

[Jeff Alton]

Matteo, I think we will have to play a similar game with your motor.....


Cheers

[911teo]

Jeff

These results are awesome... I am most impressed by the torque curve...

If I can replicate Tony's # with the 3.9L I will end up with 315 rwhp and 270 lbs/ft of torque... Maybe I'll have Tony tune mine ahahaha!

[beepbeep]

Great pull!

But what's up with AFR's? Is that 14:1 @ 6000 RPM climbing to 15:1 at end? There is couple of horses burried there and couple of knock-broken rings hovering above

[TonyG]

beepbeep

That's how the carbs came out-of-the-box. And I didn't have the proper air-correctors with me.

So I submitted the dyno run per the contest.

There's no knocking and while driving the car, you'd never know it's that lean up top.

I was supposed to take it to the track tomorrow, but that's not gonna happen until the a/f is taken care of.

Also, per the conversations with PMO, we both feel that 41mm chokes are too small and are going to install 43mm chokes.

So there's definitely going to be more power up top due to the fuel and the bigger chokes.

Hehe...I predicted 298hp but you "only" dynoed 290 I knew eight horses were hiding somewhere...

Pull that AFR down to 12.8 and it'll live longer.

[TonyG]

beepbeep

Well.... if you really want to give yourself a pat on the back, the STD Corrected Power/TQ (actual wheel HP/TQ) was 298HP.

This chart doesn't count towards the contest, but you can hang it on your wall and tell everyone that you really should have won :-)

SAE-corrected at wheels? Does it mean that it will be corrected for drivetrain loss?

298.7 hp is my best guess.

Hey, I did actually quote SAE-figure!

But now I see that I missed it by 0.24hp.
