Had my STI RA for around 4 years now and always liked the idea of having a big power RX, over the years the RA has gone through the works and is now powered by GT3040R run on a 2.35 Engine.
The car is absolutely manic, however I have now taken up the opportunity to get a Big power RX built. Current planned spec is BIG Street port, T51R Kai etc, hopefully will be running around 1.5 bar of boost.
Now the question is has anyone of a similar spec car carried out any acceleration tests etc, i.e 30-130, 60-100, anything apart from the 1/4?
We carried out extensive testing on the RA with a G Force meter and just interested in comparing results, as the RA will soon be sold and really want to move to something which will be noticeably quicker, I am hoping that the RX7 was the right candidate and does fit the bill perfectly?...
Your thoughts are appreciated.
Theres a few on here with high power rx7\'s, noticibly "Blitzboy" who i think has circa 550bhp @ 1.2bar or so and ran a 10.8 1/4 mile time.
1/4 miles times are not gonna give a fair impression as a fast 4wd gets quick times easily due to the launch and doesnt gauge the outright acceleration.
I do 30-130 in just under 9 seconds, 0-100 6.9 seconds
mark.. is that on street tyres??
ive got a friend who has quite a high power impreza and totally stripped out, when i was running around 400bhp he was also around 400bhp, we had a race on a straight road and there was not alot in it, we started at about 40 side by side and he pulled a little on me to start with then i started to pull it back higher up. He is now running around 500bhp with anti lag launch control blah blah blah, ive now got a t04r single tubby which hopefully will see me around 500 @ fly so we will have another race and i will let you know the outcome :Thumbsup!

Yes those figures are with gps timing ,Goodyear F1 GSDS ftw.
The 10.8 quarter was done on my ET streets, road tyres are useless on a drag strip you lose half a second on the launch but you should see higher terminals on road tyres
Hey D7REU... don\'t I know from somewhere :p
Glad to see you have signed up bro :)
You and Kash with big powered Rexs are going to leave me behind :(
Don\'t forget to wait for me lol
Yeah dude.... bout time you came to our forum lol.... I\'m sure the high powered boys will give you all the info you need... once you go RX7 you will never change :D

Lol, don\'t worry bro I\'m sure your\'s will be up there soon enough!
Kash, I\'ve been lurking around for the past year or so, just keeping an eye on the rotary world of things, and got to say there are some Top RX\'s about.
Quote from: BlitzBoy;601228I do 30-130 in just under 9 seconds, 0-100 6.9 seconds
Cheer Blitzboy,
Those are the figures that are very interesting.
Is that on the T04Z or that T51? and roughly what boost was that at?
That 30-130 is an excellent time , my 30-100 on the STI was 6.5 so would be probably be around the same as that time to 130..
Your 30-130 time would have placed you 3rd in the last MLR competition,:King
Andy F and Tweenie rob were 1st and 2nd wth their Monster car\'s, but 3rd was a 700HP GTR with around 9.5,,,
Need to get some RX7\'s in next year\'s competition...:mmmm
Thats on T51 with boost at 1.15 bar , have not run my 1.3 BAR setting in anger yet.
I run at 1 BAR on the road at the moment nothing gets close
Im hoping to get my 0-100 time to 6 seconds dead on the strip, but only when I stick the cage in will I turn up the boost more :3gears-rh

6 Flat will be an awesome time, sounds like it\'s an awesome setup you have.
Are you running any specific suspension setup for the strip? Or do you just set the back softer on standard coilovers?
Running HKS Drag coilovers like James Willaday who has run a 10.1, so its a proven good setup.
I set them on hard for the road and soft for the strip.
I also have a Petit Launch kit which replaces the standard arms at the rear and a diff brace and replaced the tired bushes with stock items.
Cool,
sounds good.
How much did you pick up the petit launch kit for?
I\'m probably going to be running 888\'s as well, rather than full out drag radials...

Car\'s getting built as we speak.... gonna be a monster :evillaugh
I\'ve heard rumours of the ports.... FDUKING massive! :D

I bought it off someone on the Forum it was about 250 odd if I recall, costs more new off Petit
Laeeq the porting has been started... they are meant to be BIG
Quote from: D7REU;601288Lol, don\'t worry bro I\'m sure your\'s will be up there soon enough!
When we go out cruising put it on low boost and half throttle lol... you will rinse everyone that comes out with us... all those evos and scoobys don\'t stand a chance... i feel sorry for them lol
Well I have run 0-132mph in 11.3 seconds so 30-30 should at least a second quicker.

Double post :Hammer
Brian has a T51 too bro so that should give you an idea...
So you decided to go down the T51 route... nice :Hammer
As I said no one who comes out on Saturday night will stand a chance with you Kash and myself on the scene. Now to just get JayD, Kerim and Laeeq out too and the other 30 cars will be left in our rear view mirrors lol.
T51s rule! lol Thats whats in UKs current fastest Rotary of Chris Impey\'s he run the 8.8 on the T51R KAI but has upgraded to the T51SPL now.
REworx\'s 20B RX8 also runs a T51 SPL
^ T51 ftw :D

Mark enlighten me to soften the suspension do you turn the allend key thingy in the top of the coilover clockwise or anti clock wise?
It\'s been a long time since driving this particular car so can\'t remember nowt.
rgds
Brian
for the HKS drag coilovers I go Anti Clockwise to soften Clockwise to harden
Looks like I\'ll be in good company with a Kai.
Kash the SPL will be mental on your car, especially once the boost is wound up!
Laeeq, thanks for the welcome bro. :) Have the best guys around working on the car, so God willing the car won\'t dissapoint.
These rotary\'s are pretty quick when moving then, from the times people are getting.
Rzla we got alot of competition from N.London- 600hp GT2, 750HP E6 TME, another 750HP E8, and a couple of R34\'s as well, so hurry up and get your ports done bro, that way we\'ll have a Rotary 1-3! :)
Kash wont be going anywhere until he gets a 1.5 way diff. Stock diff plus 500hp = equals bye bye me car has shat itself lol
^ lol Blitz you joker...... don\'t worry I will get the diff sorted eventually :cool
Amir yeah boi we gonna have to show those 600hp + cars what\'s up :D

correct :D

Lol, yeah.
The current record on the rollers is 790bhp from a GTR, hopefully you can come close with one of your beast\'s I\'m sure.
I told them of your abilities and they are keen to meet a RX7 guru, especially as one of the other directors has one as well. ;)

no you are not allowed stick to copying my lights home boy haha
interesting topic :)
just wondering with all this bhp talk.. 500bhp rx7 will beat any other 500/600bhp 4wd cars.. but what if it was against a 600bhp supra (or any other rwd)?
surely it would be similar pace given they weigh similar?
or am i missing sth about rotaries??
cheers :)
I think it depends on what your comparing.
A 500bhp RX7 won\'t nessecarrily beat a 500bhp 4WD car.
The RA I have weighs in at around 1220kg, and is pretty short geared even with a PPG gearset, so against it, it would be pretty close, as the gearing would play a part from a roll.
The Supra\'s are pretty heavy compared to the RX\'s so would need more power, although at top end weight would count for less, and it would depend more on Aero/turbo, setup and overall power. The rotary engine also has less drivetrain losses in comparison to Piston engines, so can put more down to the wheels at a similar flywheel power figure.
We also have a T72 powered Supra, so when the RX is out we will be able to carry out some independant testing, however I reckon it will be pretty close at 3 figure speeds, anything less and the Rotary should win due to P/W ratio.

hmmmm should be an interesting day.... let\'s see what happens :D

It\'s all about power to weight ratio.... a 500hp RX7 would give a 600hp Supra a good race... also a couple of things to note about Rotaries, as said there is less drivetrain loss compared to piston engines and drivetrains, once a rotary engine gains momentem it just keeps going, they redline at 9K
cheers guys.. this is starting to make me think 400bhp is not that much in a fc lol
and i not even got the car back nor driven it haha
lol @ L18M, 400bhp in a 1200kg car is fduking quick.
Seriously most people reading this have not been in a car with a genuine 400bhp with 1200kg kerb weight.
When you get to 470 fly then you are seriously pant wetting territory and you are making every effort to keep the car on the road and not smashing into anyone.
On the road Im running low boost approx genuine 500 fly, and you serioulsy have to concentrate on other road users in front of you.
People have these figures in there mind of what they want power, oh 500 this 600 that.
They get in my car, I scare the sh&t out of them and they saw was that the full 555?,thats too much power for the road.
I say no that was only 10 psi approx 470 off the wastegate.
Then they say I think 400bhp will be enough for themselves.
Get yourself a ride in a genuine 400hp RX and if you dont get out of the car shaking then the car doesnt have 400bhp lol

Mark you need to go out in Kash\'s car:evillaugh :evillaughand only when he gets the brakes sorted first....then in mine :2Confusedone day
Na I dont want to go in Kash\'s car at the moment as it will feel slow comparing to mine :D
When he gets the new turbo fitted and a decent diff and brakes then I might.
Yeah it will feel slower on the old setup compared to yours lol... now the new setup....hmmmm :burnout
oh and I\'ve decided I\'m gonna skip the brakes and get a parachute :D

Would agree with the above as well.
When your in a car that powerful you really need to have your wits about you. The 1st thing you notice is how much braking points change on the road.
Can\'t beat the adrenaline rush though :Giggle
Kash you need them brakes asap bro...
Also while on the topic of Diff\'s. Has anyone had any experience of the Tomei TRX 2 way diff or the Cusco RS?

Dont go 2 way for the road, only for drifting, getting lock on decell is not nice on the motorway!
Know a few people who swapped out the 2 ways in the end to 1.5 way due to them not being very driveable on the road.
Cusco diffs are good
That doesn\'t sound nice at all!
Thanks for that, 1.5 way it is then :)
Quote from: D7REU;601775Lol,
A parachute and an anchor, and you\'ll be there!. :chat
Has Kash\'s snail turned up yet dude and my bits...
can come round tonight to collect if ya like?:driving
Yeah you ideally want 1.5 as it\'s the best all round diff.... I\'ve been in a 2-way s14 a few years ago and on the street it\'s wheel-spinning everytime you accelerate lol

woah :eek.... I\'m gonna have to raise the front lol
im gonna come too on Saturday.........:Thumbsup!:Thumbsup!
i think i should take a trip over to london sometime to see all these high power rotaries :Thumbsup!
All I am going to say is FOOOOK that turbo is BIGGGG...
It is sitting here next to me and it will suck my head in quite easily
ok ok.. hav a good laugh at me lol
but i thought fd was similar weight to fc?
sweetiewells got 410bhp ish (sorry forgot the exact figure lol) n he nearly lost to a suziki swift with 250bhp ish (pls correct me chris if i got it wrong!!)
blitz: im sure you\'ll find out how quick it is.. or is not before me lol
and i was toying / dreaming of going for a t04z lol..
i think i should walk b4 i run :)
Just to add - I had a proven 420BHP Cerbera - it was quick, but for some reason it wasnt near as scary as my single turbo Rx7... I used to take people out in the Cerbera and they would say "christ thats fast" - when I take em out in my Rx7 - they get out shaking, pale and swearing they will never go out in it again!

lol liam ur a joker, how are pulling several car lengths and nearly losing the same lol. Mine is running around 410bhp and probalby weighs around standard figure. The swift i raced is around 250bhp and only weighs 700kg, was a quick little car, im sure if we had more road i would have pulled away from him alot more, wasant that long a road only got up to bout 110ish before having to slow down for roundabout
