yes multiple times 
The only fuel I use is pump, FYI water does not burn and hence is not classed as a fuel :P
500rwhp (in your dynojet language) is dead easy, well if you know how to do it i should say its easy
To ******* who dis AI? (my form being water) thats the same rubbish BS attitude/opinion that classes your ingnorance up there with pole smokers like corky taco bell. dont confuse knowledge and engineering fundamentals with hype and opinions. As Dirty Harry would say: "Cant respect a man who does not know his own limitations"
p.s. spraying water is no different to running a charge cooler, or another device to increase performance... to class a FUEL it needs to have an energy content value, and last time i looked water had ZERO

All that is left to do now is change the wastegate spring from 0.8 bar to a 1.0 bar one and back on the Dyno and re-tune the Motec ECU and if necessary up the boost a little.
I have been running around with 470rwbhp on Shell V-Power Pump Fuel 99ron for ages now, 11,000 miles worth.
The reason I want it on pump fuel is that I do a lot of Track Time on the F1 Silverstone Race Track and it is soooooooooooooooo much cheaper than Race Fuel. The Water Injection 50/50 meth and the Motec keep the A/F sweet.
Water Temps on Track sit at 70-75, Intake low 20's.
The only problem I have had is eating gearboxes, I am just having the full 5 speed Os Giken set dropped into a spare box. The lads in Japan are all running them as soon as they get to 500 fly wheel bhp.

Thats one of the main reasons we can go for the big BHP on pump fuel now and save a hell of a lot of beer tokens by not having to buy Race Fuel. HTH.
I don't think you'll make it with that turbo. (In a perfect world and set-up, that turbo is capable...on a rotary...at least that's what the math game says)
there are a few dyno charts floating around...search, and you'll see some people haven't broken 400rwhp on pump gas with that turbo.
what's up with everyone's hard on lately for 500rwhp?

Well us Australians have it on all of you and have done for a long time on normal pump fuel (95 to 98 Ron)
I shudder to think what we would make on V-Power 100, some here use it but its very expensive *relative to common dog **** fuel* and there is no need when you have water injection activated
700+ club coming soon

check out the puerto rican clubs we been runing over 500 on pump gas for many years but durability comes to question? why risk your hard earn dollar just add the some aux and boost the **** out of it and get your 500.

you could go to a shop that pumps VP air race which runs 10000000 grams of lead per litre and say you use *pump gas* to achieve 90psi boost with no intercooler and make 200000000bhp at the rear wheels
^ does that mean you could take your car set up to Bolivia and fill up at the local service station and street race a farmer in his tractor on the way home? you could but the chances of the farmer wining in his diesel tractor would be high, as your steaming heap of **** would be in multiple pieces on the side of the road with another detonated motor
yeah I talk to a few puerto ricans in florida and they say it's really not all that big of a deal to make 500 on pump but he said the same thing as you. Why risk blowing your motor just to say you do that on pump. Lets face it, if your running that much power you've probably put a quite a few bucks into your car. Why risk blowing it?

Ray Wilson(PFSupercars) just tuned a customers car with a full bridge port and T04R. At 15psi it made just over 500rwhp on pump gas. No water on meth injection either.

Seems only the internet tuners or more like the the overnight newbies especially the ones that had no idea what a turbo rotary was untill the FD came along are the ones afraid or don't have any luck running over 15psi on pump gas.
I remember when there was no turbo rotaries from mazda and we had Cartech, Arkay etc. and we were running way more than 15psi. Back then the lowest compression was what? No high octane race gas and we were still running carbs also. Good thing about those days is that we learned the hard way what really worked and what it took to make it happen. Even though we preach the same here today some people still dont get it and will not because they want to continue making the same mistakes all the time.
I've seen drawthrough turbo setups without any intercoolers running 25psi on pump gas with water injection and that was way back in the late 80's before the internet existed!
Too bad some need more than 20psi and higher than 93 octane to make 500rwhp.

Your full of it ! as if there was information before wikepedia and the fishingnet !!!
and as if there were full street rotaries running 24psi on avgas and water injection runing 9.4's @ 143mph on stock rx4 engine blocks to4e's and 55mm dcoe's....... who the **** is going to believe that
where is the BS flag hiding???

Especially since it were you aussies that were the first ones I saw way back in the last century that were running high boost without intercoolers with a little water/methanol mix.
Back then you were still runnning around in dipers weren't you Peter?
