My RX7SP build up

[RICE RACING]

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!)

(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

[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*

FUCKING LOL saw these rice and thought of you, sounds like a bargain!

[Mazdabater]

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.

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 !

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

BACK ON TOPIC!

Here is the 3 rd gear acceleration of the stock RX7 SP, tested by Motor Magazine with Correvit digital timing.

RX7SP stock 1995 test
204kw
276bhp claimed power factory rated engine (100% stock std no mods at all)

100kmh = 0 sec
110kmh = 0.87 sec
120kmh = 1.83 sec
130kmh = 2.84 sec
140kmh = 4.58 sec

RICESP
You guess the power

100kmh = 0 sec
110kmh = 0.51 sec
120kmh = 0.99 sec
130kmh = 1.51 sec
140kmh = 2.01 sec

I just found 2 original issues of Wheels Magazine from 1996 where they do a Top Speed shootout of Australia's Fastest Cars. They are on their way to me when I get them will scan the full article and put it up.

Features my two fav cars of all time Mazda RX7SP and the Ferrari F40 and a whole heap of other vastly inferior cars They also feature acceleration tests too and I will post up some more comparisons

the F40 (in my opinion) is arguably the greatest supercar of all time, and my third favorite Ferrari.

Agreed, I grew up idolizing that car my next fav was the Mazda RX7SP (IMHO it has F40 ques all over it!) Rear wing, slats, vents, Carbon in body work, turbocharged, very similar 4 stroke equivalent engine capacity, Kevlar seats, close to same weight, same power potential (when RX7 is developed properly) etc etc etc.......... and similar roots, specials made for racing.

My main goal in doing my own version of the SP concept was to equal the Ferrari F40 (< the best car ever made).

I'll put up the full test information on the Ferrari F40, the RX7SP, and RICESP and scan the article for you

p.s. Never ever thought I would own a SP with only 25 genuine versions made (this is why I never bought a copy of the magazines when they were out, did not want to depress myself !), they are rare compared to over 1300+ F40's made lol

if you don't mind, can you expand on this a bit, Rice?

It's a hard concept to relay over the internet, but I will try.

The inductive based ignition (even with HKS booster) is very limited in ability to fire and initiate spark, so much so that you end up compromising things like water rate you can use, plug gaps, heat range, ignition timing, and other parameters.... there are as a result losses of performance and non audible misfires which otherwise show up as a power loss when you test in the real world with the best equipment like the Race Logic VBOX3i (as I exclusively use).

The CD based ignition and in particular when equipped to its maximum with coil on plug system (even less losses of ign energy) just free you up to not work under the same constraints as a limited ignition systems imparts on you.

The performance I have out of RICESP now is just astounding! its a BIG JUMP over what I have listed here it's not something I am willing to share openly on forums however as always I do give about 1 million times more information for free and more openly than anyone else ever has or ever will. None of this is rocket science I need to reiterate its just repeating basic tuning knowledge as used by BMW to win the F1 world title using turbo's and also Porsche who used CD ignition on the 917/30 (nothing car that never did anything lol). For my own car I was VERY HAPPY with the way it was, but I am glad I went back to the full CD and COP set up, as I said it just another world in terms of performance levels that can be easily exploited through water injection and normal old pump petrol/gasoline

You been on ausrotary lately rice, another white SP has appeared. Some guys like it's been sitting in my dads garage for 5 years or so and he'll probably let me have it for 10k as he doesn't drive it much =/ luckiest dude around
