Now that is BAD ASS!!!!!:thumbup:
Sustained 8000 RPM and 800 Cubic Inches!!
Would your Dyno hold a Compound Supercharged Version of that engine on E-85?
Any chance of you posting the Dyno Results?
Just Askin

To my mind thats the single baddest ass mill on the market.

No air pushing bs plumbing or belts - just a straight up mill of herculean proportions.

Just awesome Alexi.

How tough would this be to close cool for saltwater purposes?

We have a remote heat exchanger we use for these types[emoji106]🏻

Badass! I was holding my breath on the sustained 8100 lol

Lol. It's really designed to be a 6700rpm motor! We are just pushing the limits. We hurt it in testing after 15 hours of beating it up their. It's happy at 7600 sustained but we released it at 6700 rev limit in that config[emoji106]🏻

Impressive that your takings on this project.


I had a 827 CID Ford and the maintenance on the 800" motors is extensive. It was an aluminum rod motor spinning 8900 and required new rods every 40 passes, and the guys running titanium rods were not getting lot more. 1.25" lift camshaft to make it run those rpms.

Even if your only spinning that motor 6700, With titanium or billet rods, I would think your gonna have longevity issues. The rod/stroke ratio is not conducive to long duration, high revving stints. There are inherent obsticals to overcome with these big engines. Just to make it run decent I bet your gonna have to use an .800" lift cam, 2.600" valve?

With the approx 5-1/2" stroke that motor is making a shit load of torque!

I hope you find the right combo and make one of these big engines live in a marine application Cool boat engine!

I dig it! I really like my TCM800 but would love a BP engine one day.

It's a 13" deck and rid ratio of a small block. It lives wide open for 15 hours straight 3 times on our DYNO at wide open. Tested at 6200 rpm for our production versions. 7600 rpm it was run and tested over 5 hours.
Anyway. Yes most big engines are a geometrical nightmare but ours is a supersized small block[emoji106]🏻

Alexi, as the deck gets taller, the heads move apart don't they? Does that mean custom intakes, longer distributor, etc.?

 

[BoostPower]

O yea! Every part we had made and now have castings for. It's it's own animal now. Nothing is shelf parts! Gonna DYNO the worn out test engine with 725hrs on it this week again. I'll post later

That is amazing; can't wait to see a pair in a boat soon.

Their are 6 in boats. I'll dig up the pics[emoji106]🏻[emoji106]🏻

I'd love to see the pic's! any updates on this motor?

 

[BoostPower]

Yes. 3 models avail. No the most popular deal as the cost is fairly high. Now we have a cast version. This is normally aspirated and in the 55k price range.[video=vimeo;154494465]https://vimeo.com/154494465[/video]
