Twin Blower Tests
#1
![Default](/forums/images/icons/icon1.gif)
We are working hard to get the first ever twin blower engines to the dyno in time to publish results in November in Key West. Two tests are scheduled; one with wedge heads, the second with Big Chief heads. The Big Chief heads flow a lot more air so they require bigger blowers and higher pulley ratios. Both systems are fuel-injected and based on cast tunnel ram intakes. Both systems use twin 1000 CFM throttle bodies and a single 900 in3 intercooler. Our trademark discharge plenum sits on top. We'll keep you posted.

Nice!
I'd like to see a Mondo blow-off valve on that 'front Y plenum'. The amount of air those 2 will push and cog belts with no slippage, I could only imagine what 'in the air off the throttle' would be like.
Great job, keep it coming!

Wedge head engine is 598 CID. Big Chief engine will be either 557 or 653 CID. The smaller engine makes more sense for the RPM. We are NOT the engine builders, but I think we are working with the best in the business. Compression ratio, cam choice and EFI tuning will be done by the engine builders, and they probably won't want to talk about it. Biggest bypass valve made is tucked in behind the bypass box. Only Merc #6 drives or bettter need apply.

TC, I know you're not the builder but, it would be nice to see the testing done on the same size motors useing the different heads. The results may be more conclusive. I'm guessing the Chiefs with a little more than the standard RV cam should make over 2.5 hp per cubic inch. Good luck!

STOP what you doing immediately!
Blower GYRO Dustin Whipple says you can't use two round blowers. You had better listen up. He is the only blower god that can make two blowers work. Good Luck!
By the way he has the best intercoolers in the business so I'de just give up.....
