Fast fd !

[RICE RACING]

It is the ONLY honest and simple quick way to know how fast you car is.......... Test the power band (3rd gear test) test the std 100kmh to 200kmh sector and see how you compare to others and to Iconic Supercars across the globe not many limitations nor excuses

Get On It :-oc==3

My car is nothing special, just an FD with non-sequential twins running about 12psi.

I also have quite a few friends with single turbo cars locally so I can try and get it in their cars for more data.

Look forward to adding you to the list

Please send me your file to peter@riceracing.com.au along with some details of the weight as tested (if you know) I'll run the power channel and send you the file back

Here is a picture of my old VBOX units, my VBOX3 and my VBOX Mini + MIM01 input box next to it.



Some calibration of the VBOX units and Neko AFR instruments I use



My new latest VBOX3i with IMU (accelarometer) + mobile harness to fit up to various test cars for hard wire in.
I LOVE THIS UNIT!!!

dont even dare think about the costs of that equipment
Bet it cost more than most well done FDs

I found the v-box test of my car in the power magazine.

I remember 21-22psi pump gas, about 1/2foul tank, me and one fellow passenger from the magazine and the equipment ofcourse.

100-200km 6,9sec.

I am very anxious to see the difference from the extra boost and power....

And without passenger in the car....

updated!

Thanks for supporting this list it will be a great thing a resource to separate fact from fiction

More technical details added to the bottom of the first post to explain to people when you have the same car with same weight then to do half the time of a stock car you need double the power! this also equals double the acceleration you record on a VBOX! (double the power equals half the time and half the distance to reach your speed increments be they 100kmh to 200kmh or 90 kmh to 140 kmh)

So in reality everything adds up perfectly

This is how I test average power increases on cars, making TRUE power gains not just at the peak last 500rpm but across the whole range more like 4000rpm

We can compare all kinds of cars and set ups, at the end of the day its all about how fast your can accelerate and how short a distance, least now you boys can see the facts behind really proven fast fd's

You will get there mate, least now you can compare to various other proven FD's around the world (the whole idea of using a VBOX and this list).

Remember F=m*a, so extra weight has an effect especially at lower speed tests like 90-140, at higher speed aero dynamic drag force plays by far the biggest part (Bugatti anyone!) there is no substitute for power and average power in the gars you choose.

100kmh to 200kmh is a fantastic practical test, and no shortage of real supercars to compare yourself with too. You may not want to do the power band test in 3rd gear though with your massive turbo, it will show up the lack of low end power and response. I will run the report anyway and post it up so people can see the effects. Again on my site the Capella on the VBOX testing page performs very badly from 4700rpm to 8000rpm in 3rd gear (over a second slower than my car).... too big a turbo and wrong porting for those revs on the street.

I fixed up some formatting on the first page, so its easier to follow for people.

Added a VBOX test of a Ferrari F40 (euro spec) this is just out of general interest as its the iconic supercar of all time! I built my RICESP to beat the Ferrari F40, which it easily does as can be seen, Ironically the run weight is IDENTICAL, the cross sectional frontal area is the same, as is the Cd, so you cant get a more even comparison, they even have the same gay rear wing and are red lol.......



Anyway I hope this inspires people to get on with maybe purchasing a Performance Box and getting out there and doing some tests and getting to know for yourself once and for all how fast your car is going with your improvements you have done after all there is nothing more satisfying than seeing with your own eyes the fruits of your hard work and money spent to make your rotary powered car a supercar crusher

Get On It people, start testing, send me those files and some specs of your FD and we will hopefully ad to this real quick with your own cars

And this is a slow lard arse *car only weight* USA spec Ferrari F40 I had corner weighted and VBOX tested by its owner, 60-130 time, these make a bit less power (closer to the factory 478bhp rating) than the cat less EURO light weight cars! anyway around 1450kg run weight full fuel inc driver
I easily beat that car, then went on to take down the much faster EURO spec F40's (which also went down!) *the faster EURO one is listed on our 100kmh to 200kmh test list*




WEIGHT WITH FULL TANKS (120lt)

Run weight and VBOX test for Euro F40 ^



Bit of info on Ferrari F40 engines here > http://www.carobu.com/Project%20Cars...40_Article.pdf inc tuning AFR on engine dyno

& http://www.carobu.com/Project%20Cars/F40.html

MAKES YOU REALLY WONDER, HOW A HEAVIER CAR WITH LESS POWER, SAME AERO LOAD (Cd & AREA) SAME GEARING FROM 100KMH TO 200KMH (I SHIFT ON MANUAL BOX) CAN BE ALLOT FASTER THAN THE PRETENDERS WITH 500RWHP, 600RWHP, 700RWHP AND SO ON lol AND THESE CUNTS RUNNING LIGHTER CARS TOO!

FACT V'S FICTION



Type:3.0/4v
Bore: 82 mm
Stroke: 69.5 mm
Compression Ratio: 7.7:1
Heads: stock (no flow chart)
Cams: std. factory grind
Induction: twin LM turbo/intercooled with Weber-Marelli injection (Razzo Rosso chip set), electronic waste-gate, standard air box and filter
Exhaust: factory 4-1 headers with LM pipes
Ignition: direct coil

This engine was tested as-is from the car, then upgraded with our LM turbo kit. This engine wasn't particularly fresh, but was representative of an average F40 engine.

Bill S from Ferrari chat who is the owner of many mega cars posted up for me his 100kmh to 200kmh time from his Ferrari Enzo, this thing is a probably a bit stronger than normal tested ones since he did a precision rebuild on the engine. Thanks very much Bill! added it to our list, here is the link to the graph, when he sends me a cleared version I'll upload it and post here too. http://www.ferrarichat.com/forum/sho...#post141406422

First page updated, format tidied up, and links put next to tested rides for further information

Expecting more results from people maybe this weekend, I'll post them up

Every time i look at the thread i see updates.
Every time i find it different and better.

I am very anxious to make the test with my car, to see the results and to see also other strong fast fd's.

PS i think i am going to use some water to my motor....

[smg944]

peter has done a nice job with this thread. i sent him over another 4 rx-7 setups to compare to with specs.
