72.5 psi

Note to forum......
None of these wierd ass metric units of measurement.

58psi "gauge pressure" as all you English loving unit types can relate too

Notice gauge starts at 2bar absolute (1 bar gauge or 14.5psi)

During qualifying they took off the waste gates and replaced them with covers, Water Injected! and Water Spray on intercoolers

58psi+ boost and more watch it here > http://www.youtube.com/watch?v=9dWLh...eature=related what 1300+bhp worth of water injection and maximum qualify boost looks like!

Jesus, @ 30sec I thought I hit the fast forward. Insane acceleration.

More development and fine tuning. Same boost getting ready for next step, proved reliability at this 1.53kg/cm setting or 140kpa gauge boost.

90-140kmh test standard.
2.51 seconds!

Would achieve 2.4x second range as last 130kmh to 140kmh zone was a little too much in the fuel setting for this qty of water injection. This is quick for a true rotary road car set up.

After the coming show (dyno day next week! *my students con'd me into taking my car* ) will do long term testing on the 1.72kg/cm or 170kpa boost level and post up the comparison results free time pending

Show update:

The dyno was drowned by water (ironic) hahaha, there was flash flooding in Melbourne and Mikes dyno was under a foot of water!.... insurance job and thus non attendance to show.

Anyway went there and displayed the car, got a large & constant crowd of people who have seen it on the roads and some who were passed at warp speed! and were fascinated to see it was water injected. Was fielding inquiries and answering question non stop for about 3 hours! The 500+bhp has spoken for itself in the last year, leaving quite an impression judging by how many people were coming to see what was under the bonnet.

Drove down to the ocean for some lunch and left a couple of Porsche 997GT2 owners totally humiliated in the wake of the mighty turbo rotary after a little challenge *they started it, I FINISHED IT!* on the highway The overall power is just amazing from 4000rpm to 8500rpm in any gear!. I'm yet to be beaten by anything out on the highway, most just hide after a little "test", not saying its the worlds quickest thing, but fuck me it hauls!, and no excuses either, just jump in drive it & power when and where its needed, no excuses, no poofter mad max ethanol drums required, unlike some!!!!

[rdgt99]

Very impressive stuff!! Also, congrats on ROTM.

[RICE RACING]

Thanks

The next stage of development has commenced and after I complete the required time & distance of durability testing I'll post up some more hard core proof of the mighty RICESP performance statistics

Will do another 100km/h to 200km/h test run and a few other measures that should get peoples juices flowing

The performance is amazing but I am more impressed with the long term durability of the package at sustained high power........... Water Injection is an amazing thing, even after so many years of being at the fore front of developing it I am still impressed by its ability to make reliable horsepower, unmatched horsepower!, while giving more durability than some making much much less!!!.

[RICE RACING]

Here is an update of the durability (measured by compression) of a stock 13B-REW (from brand new) when run at sustained high power. Taken form my postings on Aquamist Water Injection site.

All levels I have run before in my old cars and in customers ones........

Tested the compression of the engine after 1800km and its good for a rotary at around ~122psi @ 250rpm (front and rear rotor same) cranking speed. Will keep an eye over this long term.



I changed the porting specification to give the engine much more mid range power and not concentrate on top end power so much, it is quite fast on road despite relative low levels of peak power. I am projecting it will have a honest 480bhp to 500bhp (at the higher 1.4 boost setting) but will see what happens when I get around to testing this.

So a full year on and covered another 6000km (to date: all up 8200km) of testing/racing/top speed trials.
Summary: Every drive has been quite high load 90-140 testing probably around 400 or so of these tests, many 100-200kmh & 60-130mph runs (3rd to top of 4th gear) and a few top speed runs (on special test track ). Last 3000km at ~500bhp level @ 1.53kg/cm Boost level.

I did one intermediate compression test between the 1800km and this one today, but only wrote those figures down rather than taking a photo/proof. They were close to the ones today.

Rear Rotor


Front Rotor


This test was fully dry (engine run till out of fuel) and EGI disconnected, First one cant remember but I think was not as "empty" of excess fluid, this makes a high difference to rotary engine compression readings FYI.

Anyway she is not too bad, I did not think it would hold up this good especially given its a mobile test bed each and every single time it gets driven.

I have it at its new boost level of 1.7bar (around 1.75kg/cm) and it is a rocket see if she can make another year of punishment

Here is pics of the RR COP CD system mounted up (CD boxes next to battery on custom holder), wiring harness and COP's installed.

Few Grasshoppers & bugs from extensive real world testing on the front bumper! they stand no chance at "moderate" speeds













Covered 1600km in last 2 weeks big boost bro! CD makes a massive difference over the HKS DLI and stock coils/leads combo.

[RICE RACING]

Well its official CD ignition totally rapes inductive.

I set a new record for the 90-140kmh test of 2.48 seconds, going on a small incline as well this test was non ideal in the fact that the car is still learning the new boost setting so it was lacking some mid range boost which is critical for this test.

Of much more importance though is the fact that on the CD ignition I can run the engine properly the way I want and not the way the ign system wants or allows me to do. This is very important for control of charge temperature and EGT also.

I can't divulge the exact figures (as too many copy cats!) I'll let them try to make a living off my old discarded info while I will continue to test and show first hand long term how fucking good water injection is for rotaries and REAL STREET CARS! (still on petrol, and full quiet catalyst exhaust system!)

[RICE RACING]

To give this comparison test some context:
RICESP (stock std 13B-REW engine, full catalyst exhaust, T04 type turbo, plumb back waste gate, small standard inter cooler 1310kg)
*fully compliant genuine road car*

ND4SPD (Cosmo 13B, full bridge port, T51 type turbo charger, large front mounted inter cooler, gutted exhaust, open waste gate pipe 1250kg)
*quasi race car!*

I did some very interesting comparisons to ND4SPD (Mazda Capella I tuned with RRWEP110 WI) V's RICESP via the immense analysis power of the VBOX

I'll list up some comparison results: About the total FALLACY of " typical dyno sheets"! v's real world power and times taken for vehicles to actually do "work" with known levels of weight/mass!!!

This car makes on a dynohomodynamics ~390rwkw on 19psi boost (full bridge port & T51 turbo 1250kg as run at race track) where we got these recordings. You will see RICESP at 1310kg run weight is just as powerful (real rwkw! power as measured by me via VBOX!) and its just as fast in peak power band too (what really matters at the end of the day rather than poofter dyno sheet comparisons)

This report is of ND4SPD in its peak power band (6000rpm to 8200rpm) = 110kph to 150kph in 3rd gear on 19psi boost (VBOX measure = ~310rwkw owner has sheets of 380 to 390rwkw on homo dynamics guess machine)
ND4SPD = 110kmh to 150kmh = 2.07 seconds


This report shows RICESP and the first one is a FC RX7 fitted with a bridge port 13B running 15psi boost and a GT35 turbo lol (you can see I am twice as fast as it lol 4.43 seconds V's 2.06 seconds!) This car apparently makes 270rwkw dynohomodynaimcs @ 16psi boost LOL! You can see these dyno figures are not worth pissing on in the REAL WORLD! and are vastly overstated from what the cars actually makes when you apply real physics to them!!!


And the other result table is at full boost when I tuned it (ND4SPD) on road just before setting national dyno record http://www.riceracing.com.au/water-injection.htm < *read customer testimonial* (which to this day still stands!) for the only ever 13B rotary to lay down 3 back to back power runs of this level and still be able to drive home on pump petrol
Boost, EGT, RPM, AFR sensors fitted in this tuning session.
RICESP = 110kmh to 150kmh = 2.06 seconds


My RX7 is pretty quick I think you will all agree and this is still not sharing the current state of high power tune *I'll save that for another day*

Sounds like a total fucken rip off con job to me!

LOL @ the power "claims" fucken shonks! I bet they strapped them on a car and could not out accelerate a Barina! LOL ........... Sydney really needs to be bombed to get rid of all of the scum that lives there honestly shady cunts !

GET FUCKED WHY DON'T I HAVE 33K ON ME RIGHT NOW

http://cgi.ebay.com.au/Mazda-RX7-SP-...item27b9a6e292

Actually nevermind, I had a look at the pics then noticed it was a 92.

Still a nice car for a replica SP

You wont get a real one for under 90k now, last one I herd of changing hands that I did a report on for the buyer went for just under this money
