Default Fast fd !

Acceleration tests of FD rotary RX7's (VBOX data only accepted) verified by RICE RACING.
Only will accept flat road runs, any downward slopes greater then ~1.5 degree's over the length of the test will be rejected
Ranked FASTEST to SLOWEST
A little background information on acceleration times in gear/s: To do half the time of a stock weight FD you need basically double the power (simple), if you can do it in 1/3rd of the time you need 3 times the power (simple again) and so on it goes..... In your VBOX log the distance taken to achieve the speed is also exactly half if you had half the time taken, thus double the power (see proven example at end of post) eg: double the power also equals double the acceleration (Longitudinal G force average) *IT ALL ADDS UP IN REALITY! real world testing!!!*. These test really do separate the bullshit (dyno sheets) from the reality of practical acceleration tests.SEE EXAMPLE TEST @ BOTTOM OF THIS POST

OFFICIAL LIST of some real fast tuned & factory super cars & a few shit box porsches mixed in as well



EXAMPLE TEST OF PROOF OF POWER RELATIONSHIP TO TIMES TAKEN TO ACCELERATE
This is another interesting comparison: From my collection of VBOX tests http://www.riceracing.com.au/vbox-ii...ing-tuning.htm
90kmh to 135kmh (best power gearing for the stock RX7) see rpm logging.

RICESP V Spirit R Type A (stock standard)


Car specs:
Spirit R Type A
1335kg as run
280PS factory rated engine (100% stock std no mods at all)
Car ran 0-100kmh in 5.55 seconds & 13.85 second @ 104.78mph RR V-BOX Recorded for 1/4 mile *no roll out*
Time = 5.06 seconds & 158 meters

RICESP:
~21psi Rice Racing Engineered Water Injected Monster
1310kg as run
Power is over double a factory RX7 (see actual VBOX RR rwkw measure) so roughly double the power, double the acceleration & half the time required to do it and distance as well
Time = 2.21 seconds & 69 meters

VBOX File report


Another power analysis graph of RICESP using VBOX3i instrument
This is another interesting comparison: From my collection of VBOX tests http://www.riceracing.com.au/vbox-ii...ing-tuning.htm
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




VBOX proof of my figures at mid range boost on our list, HIGH BOOST VBOX runs to come stay tuned
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 !@

Steve E-Mailed me, thanks.

I did some power calcs on his ride! amazing machine. ~400+rwkw! on VBOX even have map proof of where he did his runs

That is a honest 650bhp 13B RX7 (1280kg as run total weight)
, sure its on C16 but its a street car FFS, he has done an amazing job of it.

100kmh to 200kmh in 5.16 seconds is gag factor to the max!!!!

^ Only a Buggatti Veyron is faster than his RX7 road car

Here is his official file run. Real road power included! 400+rwkw that is over 536rwhp! amazing stuff.

Wow great response........ to what is officially one of the fastest accelerating 13B RX7's in the world, better than everything other than a Buggatti Veyron!!!


Amazing!

I guess some posters here are too busy spaming the homo gay ass raping forum club to bother passing on some congrats to this bloke. Amazing! I wonder where everyone else's cars with FAKE CLAIMS of 500+rwhwp that have never ever seen a dyno let alone done an acceleration run are LOL.

Internet forums = gay!

Anyway here is his set up taken off gayclub.com

i have never really posted any of my parts list anywhere i have no problem sharing though.

-built and ported motor by me. port is judge ito based and then extended out to my liking.
-a-spec billet 6765 kit with a 1.00 a/r t4 turbine and ported H cover for fancy sound.
-power fc tuned by me
-850/2000cc injectors
-dual walbro pump and a kenne bell boost a pump
-coolingmist 250psi pump with a c10 injector 800cc running 50/50 meth
-exhaust is 3" all the way back.
-exedy twin disk setup
-3 bar map sensor
-greddy profec s bc
-blitz fmic
-alum radiator

biggest advantage i noticed with the precision billet 67 is that the turbine wheel is a regular p-trim size but looks very similar to a garrett gt wheel. which flows better vs its size. most p-trim wheels i have seen fall off at anything over 25psi. this went up to 27psi no problem and making steady power at each psi level between 23 and 27. i would have taken it all the way until the turbo ran out of steam but i needed a bigger wastegate spring as i maxed out the boost controller. i currently have a 16psi spring in there. im going to move up to a 20psi wg spring over the winter and max it out next year. car is moving very well right now so going to have some fun for the rest of the season.

You could upgrade to this wheel http://honda-tech.com/showthread.php?t=2981656

Also you mentioned that your EGTs are increasing disproportionately in top end. Maybe better exhaust setup is what is needed.
Given that 67mm billet is proven to flow north of 90 lbs/min, you should have at least another 100 HP in there.

Its shame that most people don´t realize, that you have one of the most powerful street driven rotaries around. Reading today´s internet forums makes me think, that people forgotten why they are modifying cars at the first place. Why give credits to guy who have genuine 600+ HP 13B when there are dozens of monkeys which claim 700+ and never back it up?

everyone is set on dyno numbers is the issue. most cars you see on the forums make 600+whp on my boost level. but does there car move down the road as fast? who knows. so since i posted up what it made which was 525whp on that perticular dyno it seems weak. there is actually a guy on the forum that just currently made 465whp with 370 tq on 15psi with a t04z which is a 67mm turbo. that is basicly impossible when you put the power down he will probably run the quater at 125mph trap. thats what i ran with 400whp. just the way it goes its a tuning tool. proving grounds are on the vbox or the dragstrip.

also as for the billet 67. it does flow crazy amount on the compressor side. issue is the turbine is fairly small for a rotary to make big power. i think its very well setup for a street car as i have full boost by 4k ish.. the gt style wheel precision came up with does help it flow better then a normal p-trim. there is also some gains on the exhaust but ill try the boost first and see what that does for next season.

Bumping best thread on here

140mph road car!!!!

ok took it over to the track. here are the results.

60 ft 1.91
1/8 7.12
1/8mph 107.48
1/4 10.69
1/4mph 139.88

best run with clutch getting week.

60 ft 1.78
1/8 6.89
1/8mph 108.53
1/4 popped off a coupler would have been a 10.3-10.4 at 140.5-141mph.

then i blew the clutch completely looked like and automatic with a stall lol but still ran good

60 ft. 1.76
1/8 6.92
1/8mph 103.87
1/4 10.55
1/4mph 136.04

vids will be up shortly of in car an out. now im looking for a nice clutch setup for 650whp of so. i currently have a exedy twin disc. clutch is still good but not for a sticky track with hoosiers.

check this Fd from our uk forum there goal is over 1000bhp at there target boost

http://youtu.be/dWlEvYFMFwI

James Willday 771whp then the dyno shit it - Built and Tuned by Powergains UK nothing to do with me just thought i would show you guys what some of the UK lot are doing more info on www.fduk.org

Talking Fact V's Fiction

Guess I could add my RICESP to this list

100kmh to 200kmh = 6.25 seconds.

BP Ultimate fuel, water injected. 1320kg run weight ~330rwkw VBOX power
~24psi *second lowest boost setting lol!*


90kmh to 140kmh = 2.26 seconds
100kmh to 150kmh = 2.39 seconds


Don't know of any faster? legitimate street RX7's running on Petrol only? but either way compared to the list of "supercars" I posted its right up there

Ha ha!

Funny in an ACTUAL VBOX test of a Buggatti Veyron the **** is NOT as fast as the factory claims LOL....... 15000 mile car apparently, either way. I think I might just be about to add another scalp to the RICESP super car destroyer ledger

VW Buggatti nugger 100kmh to 200kmh in 5.9 seconds VBOX verified!
