ECMs will be done by the same people that do Vortech's; i.e. Arizona Speed and Marine. In the case of the Procharger test the ECM will be done by the same guy that did it in the first place, Mark at Precision Marine.

Throttle response will not change since the position of the throttle body has not changed. Throttle bodies are huge restrictions to air flow when they close. Air always seeks the eaisest path which is back out the compressor. That's why a bypass valve is recommended at higher boost levels.

Ausome job!

I walked into the shop that is doing the first installation of this system yesterday and they had a little surprise for me. A 35 Fountain with the 502 MPIs already out and on dollies. They are putting complete XR transom assemblies and drives on the boat and the owner wants Rtech supercharger systems on the engines.

So now I'm working like a madman to finish the design of the supercooler for that engine. Nothing like a deadline to make things happen!:rolleyes:

I will post drawings ASAP.

Tom

The design was easy compared to the HP500 EFI because there isn't a headroom issue on the 35 Fountain. This design won't fit if your hatch is within 6 inches of the stock upper plenum of the intake manifold. I did it this way because it is the cleanest air flow and counter current water flow. Simple layout means a casting is not necessary; the same box and plate fabrication as the carb system works well.

Solid model shows how the bottom plate bolts on using the throttle body studs.

The box sideband and plenum divider are shown; the intercooler and the lid are not shown.

This is the blower's view of the transition into the supercooler. Connecting hose goes from 3.5" to 4". The transition takes the 4" diameter to 4.5" X 10", which is the area of the upper core.

Gee Tom, I suppose my free demo model is in the mail :)

Yeah, it's in the mail...along with the free XR drive to handle the power!:rolleyes: How's the project going? Heads show up yet? Get that engine back in the boat, I want to measure something!:D

WHAAAAA, ya don't think my BlackHawk can handle 800hp? ;)

Heads are due in today. Machine shop has been modifying them a little bit :)
Hopefully spend this weekend assembling engine and installing next weekend.
