Interesting concept. I love the way it looks with the gold wheels. I only wish I could read what the text said.
Neat project. Wonder if anyone here can read Japanese. Qurious as to what thier final HP numbers were. Looks like a very well thought out conversion. Darrell.
I´m a purist, not a fan of tweaking, much worst when the original engine design is not calculated for the forced induction...if it where a 328 turbo with a big bad turbo and the like I wouldnt find it so brutal...at least engine and gearbox components where designed and calculated for the boost increase... it looks neat even when it was made buy a bunch of friends...not a big shop judging from the pics...but for sure they have a budget, they had the right tools apparently, and enough technology to do the tunning for the new gas ratios since I guess they had to upgrade injectors, ECU´s, install intercoolers, I doubt OEM spec injectors will cope with twin turbos on a .60 trim pushing air inside...much less at some 22psi! It´s a responsable tweak, but I woudnt dare to do such mods on a maranello...they´ll use it for Drift events for sure.
For those curious to what the Japanese says you can translate manually by cut and paste into http://babelfish.altavista.com/tr e.g 1st page bottom paragraph said (very literal translation): "The muffler of マラネロ was produced. It is the one off item of the present car adjusting. Adjusting to the Fr pipe which was made already, it is production of center/Rr. While the gear - there being a BOX in the way the middle, avoiding gong plain gauze other things well bend being smallest as much as possible! With production. Fr pipe mouth of EX マニ of normal 52 Φ, Fr pipe inside diameter 57 Φ, from center Rr? It goes with Φ? ! It is perplexed to end... It made 60 Φ W! The material with SUS, the narrow Rr silencer - in order to use the space effectively finished タイコ with manual welding. As for tail position Saurus? GT? Adjusting to AERO, it produces! It is completion. The Rr silencer - you remove to the one for circuit specification, the straight tube! Way it is possible, "the straight tube" production ^ ^ Because it is the タイコ attachment, very gentle! With saying, as for V12 sound immortality? Is. Sufficiently, the level which can do also the town riding! Stopping before the police box even when, the intersection machine lining up into side, OK? ! Is." Anyway great article and photos, thanks for the link, Ron
That's interesting - thanks for the link. Reminds me of the Koenig twin turbo 550 that came out ~ 5 years ago - I remember pics of a black one making the rounds. Don't remember the HP or torque though.
Actually, they are one of the most famous and most respected tuners in Japan. Saurus. They know what they are doing I think. And of course, if you can read, you can tell the injectors are changed to Nismo 600x12 which will hold over 1200hp. Everything is of course done to support that. They are mostly GT-R tuner, but they just started doing it as there are many people asking them to do them here he said. =) He does Porsches and other imports here, but he just started doing this not long ago. =) cool though I think. =) There will be a wave of these tuners here in Japan doing F cars soon. They are out of games to play w/ Japanese cars now. =)
Sorry, my bad, I talked to Mr. Hayashi (the owner of Saurus) now, and it's 15psi at 950hp. =) Just a correction. =)
oh only at 1.0bar, and I know that turbo is good for over 2bar. They were scared about the driveline breaking, so that's why they stopped at 1.0bar I think. Our gas here is really high octane, so we can easily push 2.0 with 9.5:1 CR. I run 1.5 on my GT-R every day, and sometimes 1.8. No nocking issues at all. I guess 950hp is little much, though. he said it spins tires at 200km/h... haha.. talk about too much power. I would rather have healthy 650hp or so out of NA V12 with nice exhaust I think. Much easier to drive. I would put more money into suspension and brakes. (I guess that guy did them all, but...) Motec sounds like a very nice idea.... I am assuming the stock computer batch fires, so. (does anyone know?)
...wow, well, I guess I didnt knew a thing about this saurus japanese tuners, japanese are IMO one of the most dedicated engineers of them all...I said all that based only in the pics, I can speak english/french/spanish but my japanese is totally rusty!!!! 950hp?...wow, I´d be concerned about the driveline too but...what about torque? hp figures dont break gearboxes...torque in the other hand... If the original driveline is designed to "withstand" some 30% more stress from stock form (AKA: dependeable after 150 miles)...say 450pft torque plus 30%...that´s a whooping 585 pft of torque... oh well if you think that at some 950 horses it´ll hit something like 850pft torque...that´s allmost 300 pft torque over the mechanical limit! Im surprised the box hasnt blown yet... You are right...they know what they are doing... Did I mentioned forced induction creates more torque than HP figures? ...burnouts are BAD for your tranny!
Yeah, I will ask them about the torque numbers. =) The reason they kept it at 950hp is because of that reason... even though they treated everything in the gearbox with WPC treatment(used in race cars), which significantly helps with the cracking and all that, I can't imagine it taking more than 10% more on top. so maybe 40%? but again, some of the tranny is overbuilt, so it's hard to say. (It's irrelevant, but some of Japanese car's tranny can take over 200% more than the stock power, say, Honda, Toyota, Nissan) but I guess the starting point is much higher for Maranello.=) They used the AVS sports tires (so it's not too sticky) and somewhat easier on driveline, and they have not blown them yet I think. If they had more money,　they would have used some other transmission, but I think they didn't want to. Yeah, I am assuming it made something like 800+ torque number. (in lbft)
Thanks for that link, ajimbo. The guys seem to have done a first class job on the car, and the website has plenty of good photos documenting the work. In Japan, I have seen littre more than Tokyo. It didn't seem like the place to give such a car a good run. I hope the owner can get to some good & quiet roads to really enjoy the car's performance. It'd be a heap of fun. Forza, Pete
I think the owner of that TT car is from Indonesia. There are some twisty roads here where I live. =) but this car is definitely a higher speed GT car I think. I like highway drives more than those tight roads.
Nice - thanks for sharing the link! This is becoming more commonplace as folks want to keep their beloved (but aging) GTs somewhat competitive power wise with newer offerings. Look at the supercharger and turbo kits for Porsche 928 as an example. Only a matter of time before someone approaches (Bradan?) for a 456 kit. Nice work.
