RICESP Water Injected RX7

[RICE RACING]

O.K. Remember pump petrol/gasoline here only ! ***OFFICIAL VBOX test results***

90kmh-140kmh = 2.26 seconds!
100kmh-150kmh = 2.39 seoconds!
100kmh-200kmh = 6.25 seconds!

Still on old tires, and showing about 24psi boost on the VBOX, and ~330rwkw VBOX POWER

Tested at 1320kg run weight and 25 deg C ambient day, still doing boost learning procedure so there is a bit more in at this level and fuel mixture set rich to be on safe side.

Fact V's Fiction

Will put up some VBOX graphs when I get them off the lap dancer top

Here is the graph of the 2.26 second 90-140 test this car has a *massive* power band, not normally seen on genuine 13B road cars of this level of performance and speed!@ the word "response" does not do it justice! It builds one bar of boost at around 3400rpm in a transient test, and near its maximum boost setting well before 4600rpm and it does it even in the low gears which only take a second or two for 8000rpm, its fantastic..... best road car set up ever !@

As always, your performance tests are relentless and very informative.

Can only try to emulate the great work you did posting on that 760rwhp WI Skyline Richard

My car is getting too much for "regular testing" and it has exceeded the capacity of true street radials of normal tread wear 180 rating. I have some better 100 rating tires of a bit larger width on their way. Then I can look to do some more tests on the power of water injection in the new year....... till then I think I have deserved a well earned Christmas break and RICESP will be on "smut cruise" duties down the Beach over summer

"Got Grip C*nts" Ho Ho Ho Merry Christmas!

Fits like a finger in a bum....

looking good peter. should see those acceleration tests come down a few tenths with all that grip.

Can your WI system be used on any ECU?

Do you think you will keep increasing the boost pressure? or are you going to stop at a set amount? or is down to when you start breaking things, as always happens when gaining in HP.

Hey Mate,

My WI system can be driven off any ECU that has a PWM table and switching conditions table settings (or you can use it stand alone obviously).

I did a quick test yesterday after recalibration of my MAP sensor to match the Blitz I Color and on board internal MAP sensor in the ECU. Had to re tune the car! but basically on 180kpa gauge ~ 280kpa absolute (26.3psi or 1.85kg/cm) its accelerating harder & faster than ever before! its just unreal to me......... the thing that really gets me is I have a full computer full of logs and tests from this car, its just flat out unreal how many tests I have done with it over so many kilometers covered and YEARS!. I think as I wrote a few pages ago what I am doing now is what I thought was a limit before, and this is like the first boost control setting!

I have a local dyno competition in February that I was going to run at last year (remember it got flooded out!) and I will just leave the car as it is on 1.85kg/cm as its proven and I have lots of information from my power measures of it and see what its like on their system.
In the cooler months (remember its middle summer here) I will run out to the higher boost settings I experimented with last year. These will only be able to be used in direct drive in 4th gear on the OEM gearbox, I will run it to 2.45kg/cm or about 35psi gauge boost pressure all indications are it will do it easily as the new water injection system specification by theory and practice to date is allowing such unheard of numbers without raising a sweat.

Once there that is it for this set up. I have no more capacity in this turbocharger nor many other components, but honestly what it does now on 1.85kg boost setting is totally amazing (its proven to accelerate faster than any super car you can buy, and has an acceptable top speed of 210+MPH!!!!), I say again I have NEVER tested nor seen presented to me in any legitimate way ANY RX7 in the world running a 13B engine of any configuration on normal pump petrol that will accelerate like what I run everyday........... and the proven world leading durability I have proven here is unmatched by anyone period.

I wanted to share with you this Grant (and other keen followers)

I have tested hundreds of RX7's and tuned and modified all of the best ones in this country and beyond I have on file every combination of RX7 you can care to imagine and like I detailed in earlier pages what is most interesting to compare is how RICESP goes V's stock versions.

Well its even more interesting comparing the common std BPU (basic power up) FD3S!. These typically consists of fitting a Apexi Power FC, a full 3.5" exhaust system, a better intake and upgraded stock mount intercooler, still on stock twin turbo system. All of this results in around 230rwkw as measured on a dyno dynamics or around 190rwkw real power as measured on a VBOX

Simple physics dictates if you have the same car shape, same car mass, same gearing! to do any speed increment in half the time and half the distance you need exactly double the power. Well after checking at least half a dozen cars I have measured on my own test track and even on closed circuits when looking at a common 100kmh to 200kmh pull from 3rd gear to 4th gear... RICESP does this test in just over half the time & half the distance required by a BPU RX7!!!!! < this is fucking unreal!!!! as anyone who knows a BPU RX7 is not a slow thing at all. Typically the acceleration I get in 4th gear is higher than what you get in a BPU RX7 in 3rd gear (with exact same gearing and tires size btw).

This same theory and reality applies to any other speed measure you care to do analysis on, my famous "bullshit stops test" 90-140kmh in 3rd gear http://www.riceracing.com.au/vbox-ii...ing-tuning.htm is a classic dreamer from reality destroyer. Anyone can make a peak BS power figure but to average nearly double the power from 4700rpm to 7700rpm in this classic test really does separate the men from the Gen Y brainless know it all's LOL.

here is some more angles of RICESP, the new rear tires look SICK! I love the way it sits. And the mega motor set up, cant stop looking at this, hard to believe something so stock looking (for a genuine SP!) makes so so much power!!! From concept to proven performer

[Grant M]

great stuff Peter, once my car is running (RX4) i cant wait to order a WI system off you and start building on my cars performance. I am starting off at just 14 psi with a Borgwarner s366 turbo, but with the WI in place i want to run the engine up to 2 bar, however this will be over time and i will learn how to make my car gain the full benefits of WI!!

[Grant M]

So what is the next step in WI development? are you going to change to a larger turbo and RR street port (as you said 2 bar is about the limit where the turbo can cope) and develop a race car instead of the awesome street rotary that you have built?
