Is that the old Jason Scruggs Stratus?
According to this http://www.dragzine.com/news/testing-ensues-on-pro... it is...Yes it is. It is now owned by John Sullivan who has been 4.0 in the 1/8th on 10.5W's with a Procharger F3R 135. He tells me he can't wait to get testing the F4 when it is put into the car...
Currently the fastest Procharged car uses twin F2's. It belongs to Rick Fleck of Flex racing with 3.89 at 188mph in the 1/8 on a Pro Mod chassis.....

It's something similar to what I'm setting up for my street car....
So the competition to have the fastest Procharged car is hotting up...
Once we start to see Twin F3R Procharged cars I think that will pretty much be the limit for centri power adders.
What was in the stratos before?

Slight thread derail here - Sweet looking car you have Procharmo, have you any intentions on trying it out on the strip?
Hi, thanks and yes I do. I still have some chassis and drive chain mods to finish over the winter before I see what she will do. I also intend to see how it fairs on the twistys as well. But it will spend most of its time on the street...
Thanks for asking...

Jason Scruggs run it with a screwcharged Hemi.Is/Or was ADRL Pro Extreme record holder:

Seen Lenmar Motorsports Procharger efforts?:

Also, didn't Steve Kellet run twin prochargers on his Mustang before he sold it?

I too am looking at engineering the gear drive ratios between two similarly sized blower spinning at different speeds. But I will be running pump gas so could not use the 60+psi that Flex does....
Steve hows it going.? It's David the guy down South with the SBC twins. I'm sure you will get something going on with your twins. That is unless your looking to upgrade to an F4. LOL!!!!
Here's a vid of the twins installed and engine running...

No I never got them fitted still sat in my shop with the bbf motor
Thanks for popping on and clearing that up Steve. Any plans with a new car now or?Procharmo said:
Ok thanks. The The photo above was not the Lenmar Vette. That Vette has parallel twin F2's and the current fastest Procharged car is twin compound/staged. Big difference in boost pressure and complexity.
Sorry should of made myself more clear, Lenmar Motorsports built the car for the Clark Brothers from Texas.Here are more pics of the build:

not as good as twin turbos though...

Well Andy....Yes you are right....I Can't wait to see RV3 in the flesh...I'd like your opinion, if someone puts together a pair of offset F3R Prochargers a bit like these Vortechs. 



Do you think they (Twin F3R's)could support 4000hp? Ie make 5000hp to give 4000hp at the crank. 20% parasitic loss should stay the same at higher power levels as it does on turbos although for them it's only around 5%..LOL!
It's a shame more UK mechanical engineers don't get the lathe out and knock up gear drives like this. We'd be so much more competitive in Europe if we were a little more innovative.
Just look at the custom engineering on this Nordic twin Procharged belt drive for a street/show car....

On methanol maybe,and with a Hemi engine.But you're always fighting a parasitic loss with any crank driven supercharger which would mean spinning them harder to make more power,which makes more heat et al..
I must admit they sound the nuts though..
Some of us in europe are innovative but don't want to mess around with something that might not be as good as it looks...

Here's the Offical Procharger F4 video. No more covert Wiki leak type stuff......
Official Procharger F4


Back to the twins....Found this compound twin F2 testing video on YT.....Looks like it was an initial test for the Flex racing set up....
Twin compound F2
Sounds like they achieved 38 psi on the first stage only as the second stage is not connected to the engine...(no restriction on second blower but 38psi interstage).
It is also evident that the final setup had a reverse rotation blower as opposed to two standard rotation blowers. Could this be due to gearing and spinning them at different speeds or just to get improved pipe routing from blower to blower? What do you think?

John did go some 4.0s with the F3 setup, but it wasn't on a 10.5w, it was on big tires and at NMCA Pro Street weightGassing Station | Drag Racing | Top of Page | What's New | My Stuff
