Re: The Game Changer

We have 5 of these DD's out there now they all run great! They are 3 different types of combo's, I will say one of them swings the same 70'' 5 blade saber as most AC guy's. It does turn more pitch more RPM's than what the prop manufacture told me the hot rodded A/C guy's turn. We are testing a budge...

Re: Some real good engine prop thrust Data

When we did some thrust testing with Sensenich we found the 3 blade JX produced around 38lbs more thrust then a 4 blade R. Right now in my opinion unless your solely racing or have a very odd combo the JX is the best around blade out there for gear reducted car motors.

Re: Some real good engine prop thrust Data

Another thing I will be posting soon is we set a trigger RPM for our data logger and a max prop RPM. Then we sweep the engine thru the rpm range and we time the RPM sweep in milliseconds. The time it takes to go from idle to a set RPM. The best part is we also have a average thrust number. We will b...

This is what happens everyday with everything. If you expect aftermarket performance parts to fit. You will change that idea after a little but of experience.

There are 3 ways to do it. The important part is that your input shaft is located on the crank. YOU CAN RUN A CRANK EXTENSION OR BUY THE JW flywheel and adapter.

A great combo for you is buy the Holley 700CFM DP PN# 41778C they come with a 50cc pump on the 2nd dairies which you need one but on the primaries. So you then move the 50cc pump to the primaries. Swamping accelerator pumps and change the primary discharge nozzle to a larger .035 or .037 tube style....

Go with the new JX 3 blade we found 38lbs more thrust in the 3 blade JX than a 4 blade R @WOT not to mention a tad more thrust across the entire board. So with less surface area but creating more thrust means its a more efficient blade profile. So with less surface area you will have more top end pl...
