There is a limited number of 50 new Bathurst sp 650ps hitachi twins ever to be produced

Price is $6800 australian dollars plus postage

11 of them have been sold mostly in Australia few in Europe and 2in USA , once there all gone no more will ever be produced .

If you think my twins are fake and don't perform as I stated , then buy bnrs twins or go single what ever makes u happy no sweat off my *** .

I'll update use with 1/4 mile time as soon as I get a chance to go to track, I've been busy running my constriction business .

No cmm, but glass scales and renishaw seem to do the job...unless they're creeping opposite ways in use!

Depending on the organising body, have to swap between twins and singles for fun and games and repair old bits of cast iron crap as it occurs. I've seen the plot of yours on a dyno dynamics, best top end figure I've seen for twins, boost for boost no match for any modern single though...or the old tech we have to work with here.....unfortunately. Regarding the 650ps, you've had almost 5 years promising to do this drag thing, looks like even one of the pics with original actuators is probably from then, it's not that hard, it's every Wednesday and only a few km from your partner's place of ill-repute.

Just a fyi, if you're going to flog stuff, maybe pay to be a vendor rather than do it on the sly too?

As of today $6,800 AUD is equal to around $5,200 USD. You do realize for that much money you could buy a Borg Warner EFR turbo, manifold, downpipe, etc. everything to make it work in a FD, that's for a EFR turbo that the turbo alone costs around $2,400. There are still plenty of other turbo options that won't even exceed $1,500 USD.

You crap all over BNR's with no actual proof besides anecdotal evidence and then expect people to trust you with $5,200 USD for your turbos. If you just made this post and said "I had a unlimited budget to make the record on stock frame turbos" people would take you seriously, instead you're crapping on a another product and trying to sell your own.

You also haven't answered my questions.

Wait, that's a serious question, sorry to everyone for the multi-posts.

You really need lessons in simple math and turbo tuning before you make your posts. First its 650ps (640HP) on your magic turbos, then 280KW (375HP for BNR's which multiple people have exceeded on pump gas without water injection) and now .45bar springs on BNR turbos. .45bar is 6.5 psi, which even on the standard aftermarket 2 port boost controller would then theoretically net you only 13psi by the ultra liberal rule of doubling the spring rate of the wastegate for max psi. So by your math it wouldn't be possible to exceed 13psi on stock actuators unless you had a aftermarket three port boost controller or more advanced controller. Yet people have ran 18psi on those actuators (for nearly a decade) which given your numbers is impossible without a much higher end boost controller (which wasn't used).

In other words, if the stock actuators were that low then getting beyond 13psi on even the stock twins would be nearly impossible, which it wholly isn't.

To answer your question, people can run 18psi+ on BNR's because your numbers (.45 BAR) for the actuators are flat out wrong!

What other weird numbers do you plan to come up with?

I'm not the biggest fan of 1/4 mile times to see who is the fastest for max power on stock frame turbos. Generally you have to sacrifice a lot of down low power to maximize the peak number and unless you set the car up properly you won't have ideal results.

But if you really want that, here's the current record holder on completely stock turbos running 10.87 @ 128mph which made 411whp on the (according to you) inferior DynoJet dyno.

The dude is from the land down under and they have super restrictive car laws down there. So, there's a premium on making power in a stock format. To the point that super hot twins are a real option. Economy has been on the up down there too, so we're boned on exchange for now.

The doctor is known to be hyperbolic, but legit. Esp in the AU rotary scene.
And, to be fair the original BNRs did have a rep for leaking oil.

I wouldn't take it all so personally. This guy is just out to prove his fancy stock format parts are most excellent. There's a lot more information if you follow along on facebook.

I don't think anyone is knocking your record or BNRs. Both well respected. This guys just out for a bit of a pissing contest to prove his stuff is worth the coin.

THE DOCTOR

Hi guys
It's been a while but some updates on the car .

More tuning and now making 356rwkw
Took it to the drag strip and the axle popped out , putting a another axle today and will try again this Wednesday .

THE DOCTOR

Aslo these 650ps Bathurst sp hitachi twins turbos are now advertised in Japan through R magic
And also the twin pass intercooler with two piece carbon ducting as well .

THE DOCTOR

The magazine is revspeed

THE DOCTOR

Revspeed by Rmagic

Is that why I can't find it online anymore?

THE DOCTOR

The intercoolers are also advertised in this Japanese magazine as well
By R MAgic ( hyper revs )

THE DOCTOR

As you can see guys the Hitachi Bathurst sp 650ps twins are making the claimed powers,
R magic did some testing themselves and have advertised them in a few magazines to sell.

As for the haters and know it alls especially those super keyboard warrior ****** moderators on FD RX7 FORUM

BLACKTALON and CRAYUS ,the guys that said that twins cant make over 300rwkw ha , these clowns haven't got there cars on the road for over 5years , I'm guessing there still trying to work out how to put there engines together. again.

GOMEZ ,this guy still traumatised from getting rip off when he bought his first defective FD (yeah another guy that REALLY KNOWS HIS FDs too HA HA .

currently I see that the FDRX7 FORUM is a bit of ghost town every leaving , finally all the bullshit lying and banning of guys with real knowledge of fds only to try and make yourselfs look knowledgeable too others has all slowly ended , that's what happens when main steam media takes play.

so for the guys that want a high performance street legal car with no defects issues engineer cert etc..., the web site enquires to these upgrade are on

Will you be posting a video of the car on the dyno anytime soon?
I'm really interested in the turbos, but would like to see a dyno video.
Im not discrediting you nor saying that the turbos don't really make that type of power.

THE DOCTOR

Yes , I will do a video on the next power run .

I'm looking to make 375rwkw on 26psi

7krayziboi

iTrader: (15)

Ooh yeah !

THE DOCTOR

Power run update 365kw 25psi e85
Still more power in the hitachi Bathurst sp 650ps twins .

Nice, so it looks like you are able to get 26psi on the primary turbo as well.

At 26psi and 3,830rpm you are making 180KW

or 241hp/330ftlbs torque @ 3,830rpm.

I was expecting more torque from the primary turbo on this set-up.

You may consider putting a divider in the stock compressor outlet Y-pipe or even ditching the Y-pipe and running individual pipes from the compressor outlet into the intercooler as some have done.

I wouldn't think the turbo's dead head exhaust flow and convoluted turbo to downpipe flow (that I think will ultimately limit peak power on the twins) would affect the primary turbo operating alone.

An EFR 7670 or 8374 would be doing 400ftlbs torque by that rpm at 26psi.

I don't see anything holding your twins from making more on the primary turbo besides flow inefficiencies in the supporting equipment which you should be able to sort out.

So let me get this straight, we have more weird upside down graphs showing 489whp (also not even remotely close to your 650PS number) on a unnamed dyno brand, showing no torque curve, with no video and this all being done at 26psi on stock frame turbos.

Just to reiterate, I made 470whp and 400wtq at 19psi on BNR stage 3's, I have a dyno graph that shows torque so people can math it out and show I'm not lying, I have video of the car dynoing; to show I'm not lying, I also have multiple pictures and detailed descriptions; to show I'm not lying.

But screw it, I'll take it at your word, with all this hype about your $5,195USD stock frame turbos making 19whp more then me while running 26psi (compared to my modest 19psi). Guess I gotta make more then 489whp, post a dyno chart that shows the brand of dyno and a torque curve, and make a video as well. Hell, while we're at it; why don't you post a dyno chart that shows the brand of dyno and a torque curve, and make a video as well; should be easy given that awesome "RMagic" fame and that it's summer in Australia. I live in Cleveland Ohio so I have to wait till spring, but should be fun either way.

Sorry for wrong topic
Recently revived my GCG HT12-3kai
For my endurance race car
Just wonder whats every one thought about
Porting exhaust hot side , look quite small ...

Narfle

iTrader: (16)

I have heard the exhaust side is more restrictive on 99+ turbos.

A specialist (BNR Turbos) who manufactures large turbos on the stock frame will only use the early turbos to work with.
