dyno 02-25-2002 02:39 PM

I'll let Kaama or JimV fill you in on the details but Cord I think the carb was a 930......compression ration was 9.5 -1 I think....

kaama82 02-25-2002 10:05 PM

Ok Kaama, I'm jealous, You guys are making it hard for me to pick anybody else but JimV for my head work. Kaama I would love to hear more if you have the time. Send me an email... Thanks in advance.

Jim-was this with the crane 741 or 751 cam?

Crazyhorse 02-26-2002 05:11 PM

JimV and BJ, your work really paid off on this engine. Congratulations to you and BJ. Excellent job! Glad I could be there to watch the dyno pull. Dave

JimV 02-26-2002 05:58 PM

cam
 
Cord,

We used an Ultradyne cam slightly bigger than the 741. I dont have the specs in front of me but if your intrested I can post them




Crazyhorse,

Thank you, I wish I could have been there too!!

Crazyhorse 02-26-2002 06:04 PM

I understand you had out-of-state business. I hope it went well. You feel like meeting some of us at the Holland American Legion for a pop/beer/drink Wednesday around 5:30? By the way, Cigarette39 has a post to you on page 2, general section.

Cord 02-26-2002 06:30 PM

Na, no need to post them. I just wanted to know where we were with the 741 cam. I do need to call you some time as Bruce had some questions he wanted me to ask you. Suprisingly they were carb related!

JimV 02-27-2002 11:43 AM

kaama82, this is KAAMA (I'm at JimV's shop and using his computer) we dyno'd this engine at Tom Earhart's shop. He's got a lot of experience with marine engines and has been dynoing marine engines for about 25 years or so. He has done some dyno testing fop Merc in the past as well. I'm very pleased with the numbers! Mark

fred 02-27-2002 11:56 AM

Congrats Kaama and JimV, with the added power where do you think you will be with props?....When do you think you will be doing your first on the water testing?.....Fred

dyno 02-27-2002 12:04 PM

Fred when Kaama and I were talking sunday he was thinking he would gear up to 1.36 and maybe be able to run some props he has....28 or 30 pitch I think...

JimV 02-27-2002 12:58 PM

Mike,

Nice motor!!! How fast you goin? How big are your intake runners?

MIKEHTMSR24 02-27-2002 01:15 PM

On it's best day (85 degrees and 900 ft elev.) 1/3 tanks (about 25 gals.), 1.36 stock Bravo 1 with Imco 2" shortie, Bronson Hill 26 pitch Bravo 1 @ 5500. The shortie got me another 3.5 mph for a total of 89.7 GPS. Boat weighs about 4500 to 4700 wet.
On the rest of your question I'm sorry to say I don't know.:( Why do you ask?

JimV 02-27-2002 02:11 PM

Mike,
Im just curious about the intake volume.
