Thanks for the tune up Tyler: Dyno results on my 509

Just got home from Tyler's place with my new blown 509. Nice little tune up he put on it. Well worth hauling it a mere 4 hrs and dealing with two sets of border dummies to get the results which just happened to be way better than I had hoped for.


Yo Wallin, beat ya :)

Was there any place on the bottom of the curve where your torque was low at all? On your sheet, the first one with a magnifyer:), it is still real good at the very bottom of the sheet.

What's the A/F Left and Right? They differ quite a bit so which one is the correct one?

Ah ok that's interesting! (It said 355Dart on the dyno sheet, that's why I asked) Do you know the timing and cam numbers? My cam unfortunately still makes power at 6500.

the left one is correct. one of tylers headers had a leaky flange and it was skewing the af ratio on that side.

Ok thanks! I burned a piston at my first test run because of lack of some fuel and a non working intercooler water pickup. The motor's back in the boat with a new pickup with a completely different design. Now all I need is a couple props to test...

That doesn't surprise me! Sean is a perfectionist.

Never lets his butt crack show when he's wiping down the deck of my boat.:26:

Great job buddy.
Make sure there are a couple of extra drives around for the summer.
No use building that and going 3/4 throttle all summer.
