Nissan GT-R

[jfeagins]

I saw this discussed on another forum and thought I'd share.

"I took a little thrill ride in my son's car this afternoon and I'm still trembling. He has a Nissan GTR that he sent to TopSpeed in Atlanta to have it "Tuned" and tuning they did. It now has approximately 1000 to 1100 HP on pump gas and about 1300 to 1400 on racing fuel. Today he showed with racing fuel in the tank and I think I may have messed my pants up a little. When we returned home, I got out of the car and walked around, grabbed him by the noggin and gave him a big ole kiss and said my goodbyes to him just in case. Between me and my Valkyries and him and that car, we may not be around much longer. LOL What a heart thumpin' thrill!


First off, from what I can find on the i-net, these Nissans are advertised somewhere between 450-520ph from the factory.

Soooooooo......I gotta applaud TopSpeed in Atlanta, where this guys's son took his GT-R to have it custom tuned for having been able to double it's hp and still keep the car streetable. Second, I want some o' that there racing fuel like his son put in the tank that adds 200-300 hp. WOW! Musta been Nitro with a dual map switch for his FI system. :clapping:

Anyone else have any experience with the Nissan GT-R's bodacious horsepower making capabilities? Thoughts?

No experience at all with them but if they put out THAT kind of power I want one BAD!! :drool:

No experience with that one specifically but 1000 plus HP isn't unusual out of Nissan and Toyota "tuned" turbo applications.

I've seen a handful of street driven Supra's put 1000+ to the wheel at Dyno days. And a couple of the same ones turn 1/4 mile times in the 9's in street trim and driven to the track.

There's a LOT more than "tuning involved though. More like a ground up engine build to address rod, piston and head work. Not sure about the Nissan but the inline 6 Supras stock crank will handle that horsepower.

We're talking mods in the realm
Of $30k to $40k if paying someone.

The 350Z's bone stock engine can be pushed to close to 500hp without opening the engine up.

I'm pretty sure the GT-R uses an engine from the VQ family as well, although much hotter.

We had my wife's 350Z making 430rwhp with just an ATI Procharger and external bolt ons plus the electronics to manage the engine.

The race gas things is exactly
what was mentioned. Race gas, crank the boost way the **** up using another management map and let her rip.

I own a 2004 honda civic that I have built and raced in Georgia when I was stationed there. I've got about 450 horses at the wheels depending on how much boost I run. The car weighs 2200 pounds as I drive it so my power to weight is remarkable.
As for the GTR, if it is a Japanese version then those numbers are not very hard to get. The amount of computer tuning is remarkable to say the least. I've watched them gain 150 hp just by changing so key elements in the tuning of the main computer.
If it is a stateside version then the article failed to mention a lot of things concerning the build of the car. However, that kind of hp is doable on most 4 cylinder engines with little fuss. Like the crank, stock honda crankshafts can handle 750hp with nothing more than knife edging and balancing once assembled. The high Erving motors also lend themselves to high hp per cubic inch numbers.
I did extensive research building my honda since I was the typical old school v-8 muscle guy that talked smack to ever rice burner owner I could find. Once I got smart, I learned that if your after raw speed and not bragging rights about how many hp or liter size motor you have then the Japanese motors are something you should look into.

Alrighty then........how do we go about fitting one of the 1400hp versions into a Vmax frame, and can I make monthly payments to get it done? And where do I go, and what do I ask for, to get some of that 300hp racing fuel? My FA could use the extra thrust, and there's an "old man" up in IL talking about putting a turbo on his Gen II.

In the mean time, I'm going to study up on the GT_R's styling - so's I don't accidently tango with any of them in traffic.

The race fuel allows for higher boost level. Fully possible. The later model modular "american" 4 cylinders have been tested to those kinds of power levels too.

I ride with a guy on occasion that has a turbo Gixxer and a turbo Busa. The Busa can make over 500 HP on race fuel.

He in turn has a friend that has a Lambo the makes about 1200 HP. The Lambo regularly out runs new ZX14's and BMW 1000R's in roll-on street races. Races like 80 - 175 mph.

Turbocharged engines can make incredible numbers by just "tuning".
I bought a $299 tuner for my twin turbo F-150 and in 15 minutes I added 100 lbs of TQ and 65 HP. In a normally aspirated engine an increase like that would require several thousands of dollars in new engine parts.

The GTR is an amazing car..... even stock it can run in the 10's.

GTR's are bad ads that's for sure. Easy to make 1000 horse power in anything, you just need money......

Like Sean said the "racing fuel" isn't much more than hi octane fuel to prevent detonation when increasing boost pressure. Its to prevent blowoff on compression stroke prior to spark. That allows for increased intake pressures to start with so more fuel and higher final pressure on end of compression stroke. All of that with some timing adjustments and you get more ponies, depending on engine variables.

All that for a car that costs only $100,000 stock.... Probably has $120,000 into this one, personally if I had that kind of money I'd buy a new ZR1 Vette.

Ha ha! As soon as he get's on the throttle you can hear the launch control that comes standard in the GTR. Loads the engine, spools up the turbos......then off you go with all wheel drive.....FUN! :clapping:
