Twins with Twins, Anyone?

Day 2 at UCC, and my engine is still together.. Which makes me feel like a big winner...

Most respect for all these competitors. And special shout out to the FirePunk crew who's been graciously loaning me their forklift to unload and reload this engine every day. I've Been trying hard to convert them from the dark side. But after laying down a 7.88, I can see it's gonna require a lot more rum than I brought with me...

Nice to meet all the members who've stopped by to say hello. Tomorrow I'm packing up and heading home about 900lbs lighter. Next time you see this engine, it will be spinning and grinning.

I may have missed it but did you ever get these on a dyno?

It was great meeting you.

Mark is getting ready to do them

Nice chatting with you also Joe.

Hope Mark finds a good spot to stick it until I return. Saw a few empty chassis setting around there.. Couple guys were asking at show if turbos would clear firewall...

Yes sir, that gorgeous thing is sitting in my engine dyno room! Work of art to say the least!:thumb:

You guys need to record the festivities

You guys need to record the festivities

No doubt.. I'm pulling for a keg...

I planned to stick a scope camera into the med-duty oil pan inspection port just to monitor how the new pan baffle flows returning oil. If all good, I'll flip it over so we can watch internals spinning in action when things get real.

Fk ya that be cool!

I was over in Danville area last week on way home from Cali, but the pilot wouldn't stop so I could say hello...

Did you see me waving Mark?

:welcome:

Wrapping up the Borg Warner marine transmission pattern to dyno driveshaft adapter on engine # 2 this week.

Bearing hub assembly is done. Just waiting for our 4130 shaft with EDM splines being cut by a shop in Michigan. Then that piece gets keyed, pressed, and welded into a 1" thick 10" dia chunk of 4150 that contains the 8 bolt pattern for Danville's dyno driveshaft. Last is balance that rotating assembly, and press everything into double roller carrier bearings.

Expensive little adapter project, which I hope to justify someday...

 

[MarkBroviak]

Looking good bud! No I didn't see you waving, lol!:hug:

Coolant arrived today.

Sure hope it's worth the price. $50 a gallon, and no 50/50 mixing this stuff...

 

[lutzjk913]

You have those engines set in the boat yet?

 

[kidturbo]

Anyone have first hand experience hardening 4130 Normalized?

Had the splines cut, then double keyed this output shaft of the dyno adapter assembly. Think it should be hardened before this piece gets pressed into the 4150 driveshaft hub.

Youtube has a few examples, but I prefer comments with real world experience.

 

[kidturbo]

You have those engines set in the boat yet?

No, waiting for spot on the dyno. Sled pulling and boating season seem to conflict.

However, as of today the boat is just coming outa paint. So now the owner is anxious to get things finished in time to attend a major poker run next month.

Is there any reason you choose 4130 vs a more robust option such as 4340?

I don't have any first hand experience with it but the treatment seams to be very close to plan carbon steels which I've done.

Do you have any idea what RC hardness you are looking for?

Looks like an expensive rebranding of some brake fluid to me

Piece of 4130 is best I could come up with on short notice. No real idea on hardness. Since I don't expect it to take any hard hits on the dyno, goal is just harden those splines.
