I dunno if you have a facebook or not but its on their facebook page.

BDC is a fan of RHDJ so I'm pretty sure that completely put him on a burner

Peter, hope you fared OK with the floods in OZ!

Coming in way late but the photo quality is amazing in this build.

Hey boys

No problems here, live in the only decent part of Australia so no flooding.

Car is going great! Have a dyno competition and car show in a couple of weeks, I'll try to take some more nice pictures and add them here (oh also if you like my ride please vote for me in the car of the month > http://rotarycarclub.com/rotary_foru...ad.php?t=13228 if a rusty RX2 beats me I'll

Barry, I ave been doing allot of advanced work with the WI system, the results are very impressive indeed.

Very impressive build. Thanks for sharing and keeping us updated.

My New dash board



Nah seriously lol, it's just a random picture I got of a Lotus 98T (proper F1 car) 1986 unlimited boost era, you can see the EGT label printed up on dash under the digital display showing max of 1120 deg C and air inlet temp of 60 deg C and water temp 90 deg C....

Boost gauge goes to 5.0bar absolute (you can translate that to your backwards English units you like lol)

[TitaniumTT]

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!!!!

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
