Tiny Turbos?

[rev210]

Have a look at the new GTR's turbos here;

wheel and tyre weighs 30 kg! heavy

[GTR-32U]

Hmmm nothin a set of GTC's cant fix....

[Laurence]

I would be pretty confident that the weight of the wheels isn't the problem.

Even if they do save some weight. High offset big caliper GT-Cs would add quite a bit of ugly.

[Owgasm]

Hmm.... i can't imagine what power larger turbos would do..

oh.. i'm so over GT-C's.

[sh@un]

wow- they bought that 2009 GT-R back from the future . lol

yes, looks like Nissan used close to the smallest turbos they could get away with for the power they wanted

[typevu]

Thats why you UPGRADE the turbo and reap the benefits of MORE power

US is weird. They do years of cars by model years, not actual year built. The R35 GT-R, is a 2009 model year in the US.

Similar sizings to a 2510...

[Sydneykid]

On paper, the stock turbos look like they are good for about 600 hp, however we are seeing about 520 hp at the engine at 11-12 psi. The size of the wastegate is also something to consider. Its large, and the exhaust wheel is small.

For such low boost (11-12 psi) you would need a large turbine bypass (wastegate) on a 3.8 litre engine.

Has anyone else noticed or know why that when nissan seem to really care about a car, ie Ztune 34, GT500 cars, 35 gtr they switch from garrett to ihi turbos?

[Bliksem]

True, not only Nissan switch to IHI, alot of the Japanese aftermarket tuner's choose them... Garrett are probably able to supply them to Nissan alot more competitively than other makers. I personally would love to see the RX6B used alot more. Power Enterprise have a nice kit using it now..

I have Power Enterprise Turbo's on my car that are IHI, and when the mechanic saw them told me they wouldn't be much better then stock turbs or maybe similar to N1 turbos, but after a good tune, our jaws dropped from the power the tiny twins produced. Mind you , not from such tiny amounts of boost the R35 is using but non the less, they were very impressive, and at least a couple years old now. I rated IHI after having these turbs.

[Sarumatix]

I was standing next to a 1500hp Porsche on saturday, and the turbos didn't look much bigger .

[R338OY]

These turbos are small for a very good reason

0-100 would not be 3.6s if they were bigger. And for the car's intended purpose these turbos are fine.

If you wanted to make an extra 150kw of course you'd put bigger turbos, or a big single (harder with a V6 i guess) but you'd lose that sharp, responsive performance i'd imagine.

I'd be interested to know how much the stockie turbos can be boosted. The Skyline turbos are sh1t for big boost, so we'll see if Nissan have done the same thing with these, as a cost saving measure perhaps.

Looks like there is plenty of room to hi flow them!

[tyndago]

I said before that they were close to a 2510 size. The inducer was around 47 mm and the exducer about 42 mm. Small overall. The car makes more power than these turbos should be able to do on paper.

R35 GT-R on Mustang Dyno

I can't post numbers yet, but Edmunds Inside Line will have numbers in a few days. On a Mustang dyno, then a Dynapack Dyno.

The car made a peak of 12 psi, and then dropped off to about 10 psi by redline.

Also, only run in 3rd gear to avoid the speed limiter that has not been killed yet. Cobb should have it any day we hope. 5th gear is 1:1.

I dunno what the secrecy if for....

There are numerous dyno results floating around on the net so nothing new has been done.

[Laurence]

Well they are using a Mustang dyno. So I guess if they are Mustang sort of people it takes a long time for them to count numbers that high on their fingers.
