Blower recommendations
 

Hi, all.
As everyone on the board knows, I am now taking the Rio boat to Poker Runs. It still has the Mercury 510 ci 750hp Supercats in it. They are 12:5 race gas motors. I was looking to lower the compression and put a blower on it.
Very much unlike me, the economy being what it is, I'm looking for the least expensive setup that would work. I don't plan on running more than about 4 events a year. I would like to keep the horsepower where it is or just a little higher.
Any ideas?
Thanks,
Rich

My opinion:

Most bang for the buck: Procharger
Little more expensive but easy setup: The Blower Shop
Best there is: Whipple Charger

How about the Weiand. It was standard equipment on one of the Mercury engines. Couldn't be too bad of a unit if they used it.

You should have no problem meeting your HP with that displacement. I am running a 468 ProCharged M3SC FI at 720 HP. Turn key no problems

Big blower, turn slowly.....The guts in your super cat motors are perfect for a blower set up......I would call frank at scorpion racing engines, he is a supercat guru......Builds a lot of super cat motors for race teams......Cell is 1-734-306-4147.....

Whipple would be the best. My next choice would a TBS 871 or larger.

I agree that the whipple would be the best choice.
If you want something a bit cheaper I have a pair of 871 with superchillers. I will take 12k for the pair intakes, coolers & blowers.

I have a buddy that has a 420 if you need it, He is looking to get $1700.00 for it .:drink:

wat ever u do dont pass no cats in that boat:evilb:

Here is a pic. of the 420 .:ernaehrung004:

several good blowers out there, but answer one question, lowering the compression down to a maximum of 8 to 1 and 5-7 boost and also make sure you have a blower profile cam, you will make the same and more power with no problem...Rob

Blower Shop stuff is the best. No issues, snouts have zero issues. They just have everything figured out and their help is great! 800-950 hp or so, go with 10-71's. 950+, go with the 14-71's because you will have room to them up on race gas if you wish!

Talk to Richie Zul @ Zul Racing Engines. He just took 2 Supercat engines and put our 305's on them, think they made 1220hp. They were in a MTI @ Sarasota if you were there.

Actually, they're really bad, but really cheap. Weiand and B&M straghit cut rotors are the most inefficient roots blowers ever made. Weiand has some helix'ed rotors that weren't too bad, but the TBS is far, far better.

What do you think he lowered the compression ratio to? Or didn't he?

I was there but did not know the boat.
