Are you saying you can't produce the numbers then?

I'm willing to cover your airfare out here, Show you the dyno
numbers real time, and give you a ride showing there is NO Lag.

If my statements do not prove out you owe nothing.

If my claims hold true and we prove the low end numbers plus carry them all the way through and give you a ride showing there is no lag at all. Well then you pay for your air fare and let OSO know these claims are indeed true.

So what do ya say to that offer???

By they way pops right on plane effortlessly with out a ventilator tube.

Cheers
Jon

6800 peek ,boost at 22pd


I know alot of the street car shoot out guys are useing that style blower,But look at all the big hp makers are still using top mount blowers

Hi Gino: I got your email. Paul will be in Key West so you can discuss the details with him.

Some food for thought for this thread:

Heat Load

Boost is just a measure of how restrictive your heads and cam are. An engine that makes 1500 HP @ 15 psi needs 22 psi to make 1800 HP. So the question is "How to deal with the high intake air temperatures at this pressure?" By using an intercooler core that is 900 in3, almost 3X as big as the double core intercooler used under some PSI.

Mechanical Load

With the pulley ratio on the primary belt, the input shaft on the twin blower gearcase is spinning at ~12,000 RPM. With the pulley ratio on the secondary belts, the input shafts on the blowers are spinning at ~15,000 RPM. The Vortech step-up ratio takes this up to ~50,000 RPM at the impeller. These are big numbers, and belts and bearings have to be able to cope. We have found that it helps to split this load up between three short belts, but we still increased the size of the bearings in the gearcase and switched to ceramic balls.

Cylinder Pressure

At 1800 HP you have to ask how much more cylinder pressure can the engine stand? I would really like to see a robust 12 cylinder engine developed for this application. 50% more cylinders to share the work and 50% more holes to push the air through. On such a platform the goal would be 2000 HP @ 6000 RPM and 15 psi.

I guess it's a sign of the times; I'm starting to value reliability more than speed.

You can use all the tricks you want, all the different versions, which again will make insane hp, but cannot fill the cylinder as fast as a efficient positive displacement sc. I've been part of some big projects and I've seen them very close, but they're not the same. Certainly not the lag of the old days if done right, but its still dependent on the airflow through the exhaust.

I'm 1 person who never knocks turbos. They make great power and are great products, just anything, there's good and bad setups, but when done right, they're hard to compete with.

Just finished some testing with Tom Robinson of R-Tech.
Very inteligent man, great guy to work with and great product that really works well. We will post some number's once we get some more data. But it was really nice of Tom to take the time to drive here from Canada and be a part of this.

Below is a picture of Check300's engine pulled out for the winter for cam research Hence testing intercooler's at the same time. Old cam we started pulling and making boost at 1,750 Rpm's, New cam we started pulling and making boost at 1,850. R-Tech's product really increased the bottom end and mid range too. Boost can be made low and the throttle response is NOT lacking in any way shape or form with this set-up!

Anybody pursuing intercooler's etc., really need to get in touch with R-Tech !!

Thanks
Jon

Are those Dana's exhaust manifolds that you modified?
