Had the 509 on the dyno yesterday

[Tomas Wallin]

Yesterday we had a 12 hour dyno session.

Can't say I'm too dissapointed with the numbers :26:




The sheets are with 93 octane (869HP@5800). With 91 we got 848HP@5800.

Congrats.

[Dude! Sweet!]

Awesome! That Bravo's not going to know what hit it!

 

[Airpacker]

Nice Tomas. I hope mine looks like that at crockets next month.

A little difficult to read, but is your HP still climbing at 6300?

Yes, on another pull we made to 6500 we got 11 more HP from 6300-6500. It levels out at 5800-6000 but then it starts climbing again...

At what rpms should I prop it to get the most out of it?

I don't really want to rev more than 6000 though so I guess that is where I should aim?

Hopefully the DPM drive will withstand some more abuse than a standard XR, but if not - I have at least tried my best

 

[ThrottleUp Props]

Yes, 6000 RPM is good and actually if there is not much HP difference from 5800-6000 you could even run at 5800. If you want to fax me your dyno I am happy to have a look.

I'll do that as soon as I get the dyno files, these are just print outs but I will hopefully get all the numbers in Windyn format today.

GM 088 that had some chamber work and were increased to 120cc's. It's a 8-71 with 10% overdrive.



Thanks guys!
