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:
BH2QB9Epkv4
KtABiSbO-j0
Nix0XtJY3VI

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

[Sea-Dated]

Great numbers....


Congrats.

[Tomas Wallin]

Thanks SD

[Wobble]

great videos and sound. Excellent numbers also, congratulations.

[Dude! Sweet!]

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

[Airpacker]

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

[ThrottleUp Props]

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?

[Tomas Wallin]

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

[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.

[Griswald]

What heads and how big is that huffer?

[jeff1000man]

Good numbers. Congrats.

[BradH]

Always cool to see...thanks for posting. Good luck to ya!

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.

[Tomas Wallin]

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



Thanks guys!:)

[glh]

Nice numbers.
10# is a lot of boost, good thing you have a chiller.

[Magic Medicine]

great numbers, congrats

[rschap1]

wow!

[Trim'd Up]

Nice numbers. Makes me wanna throw a blower on my 548.

[ThrottleUp Props]

I have to agree with you on this GHL....thats A LOT of boost!

Julie

Yes but that's at 6500. At 5800-6000, where I'm going to have my wot it's at 9.5. The cooling water was starting to get pretty warm in the end of the session so I guess the chiller will do an even better job out on the water. I was very pleased to see that this old blower still makes alot of boost and does it according to the tables on BDS website.

The 856 on 91 (8.2PSI) and 870 on 93 (9.5PSI) is with no knock what so ever. :)

The dyno guy was pretty impressed of how smooth the engine runs, I guess I should thank RMBuilder for that! :seeya:

Here's a part throttle pull.

The motor is now back in the Pantera, just a couple wires left. I will do the first tests within a few weeks. Problem is I'm having huge difficulties finding any props to test here in Sweden :( I have a Merc labbed Bravo 31 and a couple 32's. But I would really like to test a couple Hydromotive's!

[Tomas Wallin]

Here's the knock and AFR curves of the 91 US (95 RON) and 93 US (98 RON) pulls.

Solid lines are 93 :)

The last pic are the power/torque of 91/93 octane

[Dude! Sweet!]

And lest we forget, Tomas boats in Sweden, in the snow, in the winter time... Should keep that monster nice and cool... Glad to see you're over here too Tomas!

Hahaha:26:

With water temps at a maximum of just above 70F during summer I guess it will run pretty well. The intercooler water on the dyno was 85-90F+ during the last pulls...

[Dude! Sweet!]

Tomas, the new interior looks freakin' AWESOME... damn shame they make you drink Heineken over there though! :D

[Dude! Sweet!]

And since you seem to get most of our American idioms... let me just say, Tomas, you are the freakin' man! :)

[Tomas Wallin]

Thanks Dude!

Yes, I'm very happy with the interior. I still need to put in a carpet though. But that's about it :)

Here's a few from last fall

[Ratickle]

Very nice......

[Tomas Wallin]

Since I broke #6 piston on the first test run after the dyno (which most likely was my own damn fault since I mounted a fuel flow sensor:confused::confused::confused:) I finally got it back in the water yesterday:26:

Had a two hour very nice ride with some easy throttling. Had a couple bursts to 5000 but that's it. I need to get some running time to get all my worries out of my head before I start retuning it. I took away some timing and added some fuel just to be on the safe side for now.

A few pics from yesterday - before I put it in, with the newly painted engine hatch. :)

[Tomas Wallin]

A couple more from yesterday. The cover shrinked a bit when I rain protected it (whatever it's called???) But I will soak it in water and put it on to have it streched again...

[JO - PANTERABOAT]

Looks very nice Tomas. You have taken very good care of it.

Stay in touch.

JO

[Ratickle]

Sweeeeeeet Tomas.


Who and what are the others in the one pic????

[Geronimo36]

nice flat torque curve

[Tomas Wallin]

Looks very nice Tomas. You have taken very good care of it.

Stay in touch.

JO
Thanks Jo, I do my best! I only need to keep adjusting my props to get it running at it's best. Right now it porpoises and chine walks a bit. I will test a std 28 Bravo next to have something to compare to.

Sweeeeeeet Tomas.


Who and what are the others in the one pic????

Thanks :)
It's Mange with his Arrow 830 and another friend with a 24 Baja.

[tomcei]

definitely looks good Tomas.
hatch came out nice too
It 's cool your sporting the flag over there:sifone:

[JO - PANTERABOAT]

Tomas,

Do you have any weight ( lead plates ) up near the bow at this time ?

JO

[Tomas Wallin]

Tomas,

JO
No nothing, that's one of the things I will be adding during my testing.

I still haven't been in any seas to mention. On completely flat it want's to porpoise pretty bad bad it only takes some ripples of 1/2 a ft to get rid of it so I guess it will be just fine really. :)

I'm still at above 20% slip with this merc labbed Bravo 31 that I had cupped and sharpened but it got 7% better from before. I'm on the right track if I can rev it all the way to 6 with the added cup...

[Mikeb4]

Boat looks just awesome Tomas! I'm adding flags this summer to mine and using your boat for placement location. Very Sharp!

[Caincando1]

Oh baby!

[Tomas Wallin]

A short clip from last saturday :)

Just cruising at around 60 with 5 people on board.

Looking Good, Tomas.


Now you need to get someone alongside filming while you're in some rougher stuff puttin that bottom design to work.....

[Tomas Wallin]

Yup! :) I do have some tuning to do before I feel safe enough to start using the throttle more active though but it's coming!

Here's another clip from sat of Mange in his Arrow 830 during a show race. I didn't participate because of the reason above :(

And I still have 800-1000rpms left :26:

It's a VIO POV cam that works very good!

[Dude! Sweet!]

Very NICE! Keep up the good work!

[jeff1000man]

Those are good numbers, but is that thing going to live making 10lbs of boost with 93 octane?

[slpcamaross97]

NICE BOAT. Just what im looking for. need one a bit closer. Interior look bad A$$.
