Got Serious P O W E R ??? !!!

[YoungPerformance]

i just find it odd that someone would be a 1200 hp motor and stick hydraulic lifter in it but then add jesel rockers and spring oilers?

Why is that?
The vast majority of my customers have no idea how to set valves, nor do they want to be bothered with having it done. The hyd. stuff is maintenance free, which can't be said of a solid roller. The hyd. setup should easily outlast a solid roller. I use Jesel shaft rockers because I want all the stability I can get at 6000 rpm. That, and it's the best.(as is T&D) Again, it is expected in an engine at that level. I think it is pretty much a most at that level. Also, by the time you add up rockers, guide plates, studs, stud girdles, etc., the shaft rockers are only about $200 more. I think that is a no brainer for $200.
The spring may or may not be needed, but they sure can't hurt. I am looking for all the longevity I can get. Hope this helps explain it.

Please excuse my ignorance.

Is the fuel delivery at the back of the blower with one huge Throttle Body?

.

No problem. The engine it has (10) 83 pound injectors inside the throttle body...

 

[Shanghied Again]

Going to need some tall scoops to cover those bad boys! :drool5:

The Engines have plenty of room under the hatches, they are actually 6" lower then the older engines.

One of my all time favorite boats. Glad to see it live again. I am curious why the engine is a wet sump oil system with that much power?

The engines are built for reliability, They are running enough HP and don't need to be dry sump to make the HP or much boost. Who needs an engine failure if a belt breaks!

Do these mills have Jesel Belt drives?

What and how were the reliability of the old Speed Racer Engines? I believe they had some Sterlings before the 1075's?

GREAT question. How many hours did the previous engines go and what probelms were encountered.

Original Engines were 1,500 Sterlings. They lasted less then a few hours. When I bought the boat(without power), I put my 1,200 Potter motors from Perfect Storm into Speed Racer. They ran perfect for two years. I sold them to generate some cash for the new motors.

The previous Potter motors went 120 hours before they were rebuilt at the end of a season

Good luck with her! that is a beautiful boat!

Sharkey nice pics ,thanks for sharing what boost,heads & hydraulic or solid cams ?:cheers2:

Thanks RHT !

I'm a photographer and will be the 1st to tell you I know nothing when it comes to building an engine...

But now that I have generated some attention with these fine mills, the owner himself Speed Racer has now signed up with Serious Offshore ! :cheers2:

and of course, Shanghied Again has most of the details as he lives with this boat all week long...

Thanks for the info and good luck with the new mills!:cheers2:

Mercury 1075 and 1200 engines are dry sump. Never heard of belts falling off on those either. Only belts I have heard of falling off were on dirt track race cars. They can fall off from debris off other cars hitting the belt. Still very rare.

 

[Coolerman]

So they addressed the dry sump vs. wet sump, did they address the Chevy style head questions?

With a good exhaust port, an efficient blower and good intercooler, with the right cam as well, you can easily make 1400hp+ with 23* chev heads.

Wow, definitely not consistent with their reputation.

The boat was purchased without power, we installed Potter Performance 1200 engines that ran excelent for 2 years. They were out of the Perfect Storm completely rebuilt. We sold the engines last year and was time to build new ones.
We never ran the sterlings.

 

[Geronimo36]

Frank, do the new mills have Jesel belt drive cams, chain or gears?

Cool, thanks for the info!

RFD ported Edelbrock Victors are good for 1200 hp naturally asperated in drag racing so they can definately flow enough air. Big Chief style heads have a whole set of valvetrain geometry issues of their own. I can see why the builder might want to avoid them. The hp limiting factor seems to be that pistons get too hot at sustained high output above 1500 hp. Am I correct on this?
