RICESP Water Injected RX7

[RICE RACING]

Many times, there is nothing of the sort worth debating, I mention it in the pre turbo thread in detail, best you read up there. I'm sure in a weak as piss cast alloy thin edge turbo you will see some wear after a while, but its going to be of no consequence compared to the wear and damage caused to your rotary engine not running water injection LOL. I have never seen any turbo ever "break" from running pre turbo, I have seen some wear, and I have seen others not show one sign of any wear at all after 100lt of use! End of the day its a non issue, and for the proven gains you get running it, well I'll let you make up your own mind

I have so many drag race customers who run it and not one has ever complained or raised it as an issue worth ringing or typing an E-Mail over. Most of these are pure methanol runners too, who use it to extend the range of their turbo to beat others who have no idea

Here is some pics of the IC spray valve, takes fluid from the WI tank, and some pics of the beast cleaned her today.

So how long does a tank of WM50 last? How many litres does the tank hold?

My tank holds about 6.5lt.

In a street application (unless you want to go to jail) you are on maximum power less than 10% of the time you are running the engine. One tank of fluid will last me a long time.

I run the car very hard and use more full power than the 10% typically I fill it with 20lt at a time (main fuel tank) and before each run (every weekend!!! for the last 3 years!!!) I'll pop the bonnet and just stare at my handy work and check out everything and open up the WM50 tank and check the level, I top it up every second week or so, and only put in maybe 2lt at a time, I generally don't ever let the tank go below half when used like this. It does use allot more fluid now that I spray the IC at a greater rate as well to keep the charge temp in check for maximum power.

Once you get used to running WI like this and its in your blood simply checking the tank every second or third time you drive it is easy if its a weekend car and it becomes second nature. Around 6lt is the ideal size for me.

Took the bad boy out today

Got it on around 28.5~28.0psi across the rev range, about ~1.9bar region.
As the boost is going up the peak power range creeps up, peak is not happening at around 7700rpm to 7800rpm, in 3rd gear I get well over 15psi @ 3800rpm.
The car is very quick and with the new rear tires has a high level of traction to use all of the power this boost level produces (on a decent, dry, straight road surface!@).
Was driving the other day and pulled the 2nd,3rd,4th gear to 8500rpm and a mate herd it over the mountains near where he was, and thought it was a motor bike ! crazy bit of gear it is. The acceleration and velocity you can reach on just the shortest stretches of tarmac are extraordinary indeed.

I'll leave it at this setting and enjoy it for a while before again doing the over 2 bar gauge boost long term settings, I'll leave that for our mild autumn/winter/spring period

(Peak power band for all cars)

60mph-90mph
EURO F40 = 2.70 seconds
USA F40 = 2.90 seconds
RICESP = 2.59 seconds

70mph-90mph
EURO F40 = 1.90 seconds
USA F40 = 2.10 seconds
RICESP = 1.76 seconds

Further update to this post off page 13 (way back).

Current VBOX tests @ last stage of boost increase ~ 1.85kg/cm
60mph-90mph = 2.29 seconds
&
70mph-90mph = 1.65 seconds

Makes the F40 look slow now

This is great reference for you.

86mph the 638bhp ZR-1 pulls 0.44G Mine 0.570G

110mph 0.31G Mine 0.411G

ZR-1 = 3350lb as tested
RICESP = 2910lb as tested

Power peak for both cars in two different gear (you can guess the power of my car) it's somewhere around/near/over? 600bhp as remember at higher speeds aero dynamic loads play more effect than weight

100kmh to 200kmh

ZR-1 = about 7.2 seconds
RICESP = 6.2 seconds

what do you think you torque is with the 600HP you have got? i should imagine it is somewhere near the same figure?

[Dust]

With the control valve, how low have you gotten water flow?

It's around 61+kg ~600+Nm figure. Pure function of the low down power of the standard porting, while the peak power is impressive its the mid range that is even more so. Clutch is rated to ~67kg and if it is not warmed up (due to it being carbon) it will slip marginally the first time you get on the power, so it has some grunt
