I have edited video showing the beast (beating all but 1 F40 and having no respect for tire grip!) , but youtube is going BDC style and failing on me :ack2: so until then here is some reading :)

"Here's the raw Excel data for the fastest 60 to 130 in 9.4 seconds. Do not use data before 60 mph or after 130 mph since I may let up before or after that.

I weighed the car right after the runs:

2,917 lbs (1323kg) without driver
3,113 lbs (1412kg!) with driver "
(note 478bhp rated motor)

Car does 60mph to 85mph in ~2.10 seconds compared to RICESP 2.23 seconds :) *I need to turn the boost up just a little* ~5k to 7krpm for both vehicles. I estimate my thing has around ~440bhp on ~17psi setting, aiming for honest ~500 honest bhp on 1.5bar boost setting, which should achieve the goal of matching/beating? the F40. My power figure average for the SP is ~270rwkw on my VBOX measure (going off my experience * 1.2 = engine power = ~435bhp)

http://www.ferrarichat.com/forum/att...1&d=1272234182

60mph to 85mph now is .......................... 2.11 seconds basically exactly equal to the USA F40 for which I have a VBOX test from an owner *above* his was on small decent too! so artificially fast in my books.
100-140kmh is 2.10 seconds 70.36 meters (EURO F40 apparently does 2.0 seconds and 67.60 meters but have only ever found one magazine test on that, fastest one ever recorded too btw) listed earlier on.

Basically It's allot faster than the all but one of the Ferrari F40's listed *euro F40 Italian test, probably a boosted up special lol* (USA ones tested by Road and Track I obliterate in same rpm speed tests.)

I have a video of it and will do up a VBOX report showing the boost, back pressure, EGT, Turbine speed, and all the shit I do...... its a very impressive car for what it is. Hiring an air port not far from me for some high speed testing and full performance review. If you compare it to the Domar Jap 500ps cars that cant char the semi slicks as hard as mine nor accelerate no where near as quickly its even more impressive. I love it.

Additional information 17th Dec 2010 test update
60-130mph for RICESP at Aerodrome test is 8.62 seconds (lot faster than the VBOX proof from the F40)

As fast as a Pagani Zonda and Ferrari F40, I'll put up the VBOX proof later :hurray:

Pete, out of inane curiousity.... what is the highest peak g-force you've managed to log or come across on 'street' tyres? .72 looks pretty good.
i have had cars pull over 1G of accelleration (around 1-1.15G actually)on the street on street tyres,all have been evo's or wrx's or sti's though,i have had my rx7 as hi as 0.95G on the street,and some other cars in the hi 0.8's,all rwd and in the 12 sec bracket.that should give u an idea :D

i can garauntee the peak g reading u get on the v box will be in first gear,unless ur getting heavy wheelspin,but i doubt it,adn a low 13sec car will not pull 0.72G in second gear thats for sure.

my 1150kg rx7 with 360rwhp and toyo proxes tyres does just over 0.8G in second gear,thats zero wheelpsin and all power,and about 0.65G in 3rd,to give u an idea again,thats harder than most cars pull in first,and im in 3rd :lol:

also,u need a G graph,as peak doesnt give u a true idea,if u have huge grip and no power,u can give a huge dump and create a massive g froce spike on launch but it may only last an instant,then falls away to the normal g force.

Please tell me what G you have @ exactly 130kph in 3rd gear when doing a pull from 100 to 160kph *no gear change shunts*.... If you can tell me any G between revs of 6600rpm to 8000rpm in 3rd gear, but preferably at the above road speed to compare and apple to an apple
I tested a car today on road tires 235's that did a honest 0.657G :bow: which is 35% more G than a Pagani Zonda !!!!! which is at its power peak at that speed.
This car 11.4% wheel slip (so near perfect traction capacity) @ 24psi gauge boost pressure 2.6bar absolute pressure *948kpa and 35 deg C! test conditions*.Pump fuel and my WATER INJECTION

The car I tested has 260% more acceleration force than a Spirit R type A @ 130kph which in its own right is not a slow car :laugh:

**110kph to 144kph** (all listed in one gear with no changes involved)
1.55 sec in 54 meters
^ test car
1.83 sec in 65 meters
^ Pagani Zonda
2.42 sec in 86 meters
^ F360 Ferrari
2.91 sec in 103 meters
^ 230rwkw Spirit R Type A

RICESP is 1.84 seconds in 65.38 meters
*Pagani Zonda its test is slighly down hill so I will call myself just as fast! probably faster, have more top end G *acceleration* where as it's Mazzive 6+lt N/A V12 has a superior spread of power*. (It traps 128mph in 400m test) we both do similar 0-100kmh times for what its worth (within 0.1 seconds). I'll update with a full test when time permits ;) along with overlays between the two cars :)


EDIT (additional info, back up of first result)
17th Dec 2010 TESTS RICESP is 1.82 seconds in 64.53 meters *From Aerodrome test* SO ITS *officially* FASTER THAN A ZONDA !

RICE RACING 12-10-2010 08:36 PM

:conehead: Here is the graph showing some detail of various parameters & performance. Average figures between test lines shown (Avg-b) *report screen* and peak on datum line of graph in top left box snapshot of instant Graph data figures at that point.

I'll post up some other incremental times of the F40, I have 3 separate tests (one factory) two independent (USA and UERO models) and on peak power band test 60mph to 90mph and 70mph to 90mph I have ........

(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


^ back this up with 2.56 and 1.73 seconds (on a quite damp track too) ;) so no one hit wonder :)

Just out of curiosity how is your bottom end. Do you have enough pull out of corners IE is the car good for the track or just high power runs?

Did you watch the youtube video? it is insane. for spread of power. In 2nd gear I just roll onto it really gently as if I stab it at low revs I end up off the road (this is why I have traction control fitted, but turned off in that vid to illustrate the power).

I have full 20psi boost at 4400rpm (not just the boost but the power is very strong from these revs onwards, its average power is flat out unreal from 4k to 8k rpm very flexible for a 13B engine) :auto: the whole set up is more around mid range power rather than anything to do with top end :coolgleamA:

I could improve it even more by dropping the exhaust system pressure by not running a catalyst, but I like it legal and the sound is really nice too in note and volume.

Well I am impressed that you are running a cat converter. This is something I will have to install this year. Just surprised you do not burn through those cat converters. Do you have a air pump attached to your catalyst? Do you have to pass emissions?

Trout2 12-11-2010 05:21 PM

You tube says you're video is private.

We have 3 gas analysis machines at work and the emissions are better than original and well under the specifications. I spent allot of time on fuel atomization and tuning to make that happen and also to make the CAT's live.

On that side I only use SMB & Performance Weaponry Catalysts, this has been a long term test project between us on this and their offering has delivered in power and durability and ultimately measured performance against known iconic cars :) it's nice to have the real engineering data on their abilities too showing the effect of pressure and turbine response and to a greater degree the power restriction in running such a device in a car of this proven power and performance.

Last time I checked the CAT it was excellent, I believe the only thing that kills these types of things is long term running on non ideal *chemically correct* mixtures at low speeds (especially cruise) where the rich mixture has time to react in the body and thus overheat and kill it. Full throttle and high gas flows dont kill cats as there is not enough time for the reaction to happen and thus little more temp build up apart from what is in the system at the point anyway *and this is reflected in the beginning and end AFR value you measure*.

Glad you like it :) I absolutely love it :302: was always my goal to equal Ferrari F40 performance, infact its better than allot of modern day alternatives... even the famed ZRI that only generates 0.48G accel at 81mph or 130kmh V's my RICESP @ 0.52G :fawk:

Wow! Emissions legal. Your impressive numbers are even more impressive now.

Thanks man,

I worked very hard to achieve this set up :117:
It was allot of fun doing the research and also history check of the supercars I compare my RICESP special too :hurray:

Not sure if most appreciate it :dunno: but there is a full time job alone in learning all of the VBOX stuff and the way I have applied it to measure power and do the things I want it to do. It's been a great adventure along the way, had the odd little set back :angelsad2: but I worked it all out and with the support of some great friends giving me motivation more than anything I showed that despite ANY set back or numerous hater attacks against you that you can win through and class/brains/god given talent wins in the end, no matter what haters/cunts may say about you or your car :Angel_anim:

Like we all know, its easy to open your wallet and charge up the credit card to get people to build you a car or many parts of it, its another thing all together to design, build, tune, and test/prove it all 100% yourself :reddevil:

NoDOHC 12-13-2010 09:49 PM

That is a fact. It may cost more, but you get the knowlege too.

I would love to be able to afford your toys and do my own development (I can barely afford to pay a couple hundred bucks for a dyno pull).

For the record, your car pulls harder in 3rd than mine does in 2nd. INSANE!

Keep up the good work!

RICE RACING 12-17-2010 10:36 PM

New record for my little cat equipped road going RX7 100kmh to 200kmh of 7.53 seconds! :auto: :fawk:
