ROO SHOOTER....is the new world record holder in its class after a successful event on the salt flats in Sth Aust. The new class record for F/CPRO is 117.8 mph this was achieved using type 4 power plant of 2.7 .
After 2 years of false starts the Ratmuller race team finally got our 57 kombi on the salt and ripped up the old record of 100.3 mph, the reception was fantastic ....the old girl is ready for Day of the Drags this weekend at Eastern Creek.

Good work guys!!
That would be a lot of fun.
Over what distance do you run?
I think I would need around 2 ks or more to get through my 6 gears but that's on tar, no calculations.
If I reached 8000rpm in 6th it should see 218 mph (353kph) with a rev limit of 10000. With well over 700hp
But I don't think i have the balls!!!!

Need to do some work on aerodynamics Aaron at that kind of speed lol
Call on crazy col and his roll of aerodynamic tape!! Hahaha

Well done Steve!
I think Aaron has speeding ticket with faster speeds than that.
Does that count as a "record"?
HappyDaze 路
Different sort of "record".馃憤

Thanks guy's....the rotary bus would be in a different class to start, 700hp will be scary stuff compared to our 180hp. the world record stands for 2-3 litre engined powered cars...we now hold this record...Arrons will compete against other bigger engined cars BUT would be sooooo cool to have 2 kombi's hold world records...let you know what speed you need to beat. We also hold title to the fastest vw aircooled powered vw bus in the world,that record stood at 109mph..we have offered a $250.00 cash prize for someone to top this on the salt whether it be here or in bonnieville....so get that big block aircooled ready cheers steve

Where can I find the class regulations for F/CPRO and similar?

Peter the regs are very much a pain in the arse.....nothing that cams approve work for the DLRA as we must follow the yanks for some reason.....you can own a v8 super car front seat that is capable of 300+ BUT you must use a alloy seat ....go figure . The whole process is a bit of a pain espeacially if you build a car that you want to use in various forms of motor sport. Happy to share info with anyone who is thinking of running this event next year cheers steve
HappyDaze 路
You're right there, Steve......The DLRA scrutineers 'knocked back' my brand new CAMS approved helmet, because it didn't have a Snell mark. Eventually, when the chief scrutineer saw the CAMS manual [luckily I took it along], that showed the equivalent standards, all was OK.

Indeed, I've carefully read my way throught the DRLA regs and still haven't managed to clear some significant doubts; however, I can see why the Roo Shooter was a good choice of platform for F/CPRO. Well done.

congratulations anything faster than 130 ks is scary in a kombi

Tough ask to get a bay as light as a split!! Definitely need a bit of time spent in the Westside workshop with lots of cutting lol

To be honest weight is your friend on the salt ...better traction at high speed....you need to think away from drag racing where power to weight is more desired over a short distance. A lot of the 200 mph + cars add lead ballast to help keep them on planet earth....so the magic air wall will keep you speeds down and you require more torque to climb over .....a bay window will be fine and is a lot more aero than a splitty too. A Type 1 donk may not produce enough torque at high rpm's to help push the brick through the air...this is why in the states the top speed splitty on the salt was 109mph....with a different top gear ratio we feel the bus is capable of 125-130 mph currently our set up was 5200rpm in 4th 117.8mph...we worked for max torque...its all fun and hard to honestly work out...other cars are so much more aero than a bus so information is very very light on , we more or less are pioneeers in this style of racing with such large frontal area of a bus to contend with.......can't ask the guy next door what did you run etc etc cheers steve
LIFE IN THE LOW LANE 路
Ok makes sense Steve!! Have got a 2960cc type 4 on the way for the bus so it should have plenty of torque!!
good idea..see if I can manage to get myself there....cheers Ian.

I was standing at the start line when the Roo Shooter shot off into the distance breaking that world record. The sight of an early splitty spreading the salt was amazing and even more amazing was the end result.
Now based on Steve's earlier comments that weight is your friend on the salt then I am thinking that if could find a wide park bench that would meet all the DLRA rules and regulations then I might be able to fit my well proportioned arse into the park bench and go for a run in the Roo Shooter next year.
Me having a go at Land Speed Racing, maybe I would have to rename it the Poo Shooter to match any skidmarks.
Was thinking the next Volkswagen on the salt maybe a
Country Buggy as these were so built for speed............imagine running 2.9 litre TDI mounted midships and matched to a DSG gear box..

Sounds like the big type 4 is doing it pretty easy only at 5200rpm!
Can you share some specifications on your big Type 4 Steve?
What work is done to the oil system?
I always think about those sustained high rpm runs draining the sump.
Dry sump would be a great mod!
Kombi_Rescue 路
Hi Dave, the big type 4 runs a relatively standard oiling system.....we use a porsche fan and a remote cooler that is only relying on bypass air to cool and is located behind the front axle. Fat performance [Rod flemming] supplied a melling oil pump, camshaft, lifters 104.7 barrel and piston assy.The crankshaft is a scat unit along with individual split port cylinder heads,,,,rods are H beam units.The ignition system is a magna spark fro CB performance and run 51.5 IDA's. Compression is 11.4 and we run 98 pump gas....soon to try E85. Our fuel system is not correctly tuned and have lean out issues due to the bowl cc in the IDA's on long straights.The bus is more than capable to run much higher speeds and have calculated at least 125mph to the 130mph range. Crankcase pressure with the large 104 bore causes enough issues with a continuous fill up of oil in our breather box that's 5liter container ...vacum pump and a dry sump are the next improvements and hopfully give us even more hp.cheers steve
