As many of you know, we have had good results from the Supercooler dyno tests and in water testing that we have done. Those of you who don't know can check the website www.rtechperformance.com.

Recently we applied what we have learned to the current problem with large displacement blower engines, typically equipped with 14-71 Roots style blowers. Due to the lower efficiency of these blowers and the limited room for the intercooler these engines are limited to about 1000 HP (pleasure) or 1300 HP (race).

We built the setup pictured below to display at the Miami boat show, but we're dying to test it. Yes, it looks different, but remember, the blower and supercooler technology you're looking at is proven. Centrifugal compressors have very high efficiency and the supercooler is the largest you can fit in the room available between the blowers and the 2000 CFM Holley throttle body. Heads are Big Chief, intake is port injected.

Is there anybody out there who is game to try this? The ideal candidate is a tall deck block with very good heads and ~9:1 compression. If you already have the 14-71 that's even better. We can do back to back testing of the two systems.

Oh yeah, we left the sides of the supercooler out for display so people could see the insides.

Cool setup. I think that you will need a idler pully in the middle of the V instead of the tensioner and put the tensioner on the last segment of the beltjust before the 'slack side' before the crank pully. Can't wait to see it go together.

Thanks guys...if more is better, then TWO much is just right! More airflow and less temperature are never bad.

Too Old - I'm hoping that a demonstration of firepower will help make engine builders more comfortable with our single blower setup making 1000 HP. NEVRENUFF volunteered from OSO, so I figure this is the best place to find a volunteer for the twin blower.

Marty - I think you're right, this drive was put together in a hurry for the show. Also the pulleys and belt shown are 10 rib. They were the only pulleys I had on hand and I actually cut two ribs off the 12 rib belt to fit them. A 12 rib belt will be used with 12 rib pulleys when I get them.

sutphen30: There are two blowers and the intercooler core is twice as much money, but the supercooler box and the drive are really only 1-1/2 times as much work. Then you would have the cost of the EFI system as well. So blower and EFI might cost about $15,000.00.

When Chief engines charges $75,000.00 for a 1400 HP engine with a 14-71 and EFI, I don't think this is out of line for the gains in HP and reliability.

Interesting concept with the headder design. I assume that it scavenges exhaust much better due to the firing order of the BBC?

I'm not involved but I know of some testing that's going on. What issue of Hot Rod?

Attached picture is from the May issue of Family & Performance Boating. Great coverage of the Miami show. A good editorial about the contraversy surrounding the V-hull record battle going on between Fountain and Outer Limits. I heard a rumour that the engines Reggie will use to set the new record will be centrifugally supercharged.

Latest Hot Rod mag has little blurb about a Procharged 572 that is being built to make 2000 HP. I tell you centrifugal blowers are going to rise up in the blower battles.
