RICESP Water Injected RX7

[Richard L]

A project like this is highly entertaining and rewarding especially as each little mystery is uncovered, enabling you to extract more and more power safely with water injection.

[RICE RACING]

Finished the tests with the OEM based inductive ignition, been good to work with it for a while to find exact limits of it with regards to water injection usage. Have fitted up a new specification Capacitive Discharge Ignition and it is like night and day difference in power, response, and engine running...... whole new world of options for setting the engine to make the most of water injection.

Where it is now is like its base. So far in only last couple of days I have been able to implement a whole new strategy for setting of the water injection system, to the benefit of the charge temperature, also showing a noticeable increase in performance Have a whole lot of tests scheduled over the next couple of months. Car is a total addiction it's better than any heroin hit, get massive withdrawals if I don't drive it every week, the performance is flat out gag factor! I have to be real careful each time I drive it though the speed attainable (you need to remember its so easily accessed being a true road car!) reaches high levels. See this for some context! > http://www.youtube.com/watch?v=nmFTy...eature=related and remember RICESP in its ~20psi guise is already faster than this all time legend

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

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

The engine bay is awesome as usual!
Very very clean.

Well its official CD ignition totally rapes inductive.

This morning 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 13: 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!)

(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

New Figures for the last test compared to the Ferrari F40.

60mph-90mph
RICESP = 2.42 seconds

70mph-90mph
RICESP = 1.64 seconds

I still have some fine tuning to do and a couple more little tricks up my sleeve then will organize another test to do a new 100kmh to 200kmh figure

HIGH BOOST BRO! RRWEP110 Water Injected.

~30psi on pump petrol and water injected

[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*

Yes, Yes it is Richard

I need to say again none of this is possible without the water injection, that is the key element and common thread to all of my own and my customers victories over un reliability and general limitations when running commonly available real petrol (or even racing fuels for that matter!).

Typed words can't do the VBOX analysis and seat of the pants feelings justice... people really need to go in a properly set up water injected car and better yet live with one for a few months to get the full experience of being able to drive around a normal car, fill it up anywhere you wish (on any fuel grade available) and to still experience the full power a turbocharger can physically produce without excuse or qualification or fear of engine or turbo melt down is what separates the wannabe's and MAD MAX fuel drum couriers from the real men who have worked out how to make full power on normal gasoline/petrol. The ones who can drive their cars anywhere, anytime, and enjoy them from the ones who need to fund endless rebuilds and extortion type prices for "race fuel" to make their turbo charged cars perform anywhere near their full potential.

I openly laugh at people who are trying to address issues of "not enough cooling" by positioning random injectors (extra ones) to cool down their charge or any such other garbage to stop their engines from turning to rubbish every few minutes of use those types just have NO IDEA! No education in engineering, and worse still far too much arrogance to accept that Water Injection solved all of these problems nearly 100 years ago now.

In a way its good that people are so stupid you know, it means that the type of world leading performance I obtain and give to smart people will not be common place, and that just means you and I and people like us are the lucky few who get to experience this technology and enjoy it, while the doubters and nay say types will keep on making the same mistakes over and over to their own detriment ......... can't say we are hiding the secrets to speed, power and durability, the formula is there if you are open minded enough to follow the leaders

I have some even more telling comparison reports which I should get around to posting up here for all interested.

It collates:

A) 36psi ~3.2lt OLD Holden "202" 1070kg Lenco 5 speed clutch less shift drag car *6.6 seconds @ 110mph in 1/8th mile*

B) ND4SPD 600rwhp 2.6lt 13B Cosmo powered Capella on 27psi boost

C) RICESP 1310kg on ~21psi full street trim set up basically a perfectly tuned and set up standard vehicle!!!

All three cars accelerating as hard as possible from speed increment 100kmh to 150kmh, some would be shocked to see who is fastest and takes the least distance to do it.... All data logged by me with the VBOX 3i all logged AFR, boost pressures, times, speeds and vehicle mass and all in their happy environments and running at maximum potentials, no excuses (lack of traction bro, missed shift bro, no C16 bro!!!), no BS, just pure hard core facts and testing from the Don of reality V's FICTION (other internet ranters who have no cars, no testing equipment, no qualifications!)

Lots (too much) absolute BS! spread about the internets in the rotary world about the POWER of bridge ports and boost response blah blah blah, I single handed disprove ALL of the garbage talk with my own stock std engined car, running a fully legal set up too! .......... it would be really funny if it were not so disturbing of the number of people who listen to random unqualified advise off forums across the world without ever asking for proof like I have managed to collect on the merits of various set ups and their ACTUAL RESULTS!. Oh well I suppose that is what happens when people listen to clowns who got their qualifications from the internet or a corflakes packet rather than a legitimate school or real world experience and properly backed up testing!
