What's The Most Powerful Rb26dett Out There???

[slydar]

penzoil GTR, 1600 may be the upper limit of a stock block, but in a drag application, the water jackets can be grout filled, increasing the block rigidity, and therefore horsepower ceiling, not too useful for tootling down to the shops, but then neither is 1600ps

If anybody here has seen the Best Motoring Video with Tsuchiya and Orido testing the Mine's R34 GTR VSPEC II, you would know how powerful that engine is.

From what I saw, they both quickly stated that it was too fast as they were barreling down the straight and into the corners of the test track, and they are both JGTC Drivers, so they are used to speed everyday. It accelerates like a street bike, and that is the fastest, or most balanced and powerful RB26 I've ever seen

The Mines cars are always no joke....

They always look stock - are about the fastest cars out there....

The way that car goes though the rev range is Amazing.....


As far as the limits of the motor - there is no such thing as a defined limit at above 1000hp...

Its so close to the edge - that anything can cause a failure....

Which one was it in? I'm gonna order one sooner or later

Now, that's my style of car

That Mines car in Best Motoring 5 is a real cool TRACK car, but nowhere near the most powerful.
It only had twin GT2530's which are not that big, but perfect for track use. That car probably only had around 600hp at the engine which is HUGE for a track car, but nowhere near the most powerful.
Well the HKS skyline is the fastest, and that has what? Around 1400hp?

And what are u talking about that displacement puts down horsepower?
More displacement equals more gas and thus spins turbos earlier and more quickly.
All the drag cars are at least 2.8L
Mario has a 3L OS Giken dont he?

With the increase in displacement you are changing a lot of factors including the strength of the block itself. Those cars that are running 2.8 liters usually have a relativly short lifespan.

Most big HP engines have a short lifespan

Have had the opertunity to talk through an interpreter to Mr. Nagata of Top Secret even the top guys have block failure once you begin to breach the 1,100hp mark. Even the mighty N1 blocks can still crack in the same place between the #3 and #4 cylinders. It would seem to be a design flaw in the block itself.

Now is some smart and rich cookie were to invest in the dies and have a really nice alloy block made for racing applications he just may have found a cure and also a way to become rather wealthy.

That is sort of an inside joke to some of the guys on here. Some kid claimed to have a NUR 400 Spec II(or something like that) here in the states. Needless to say the kid was full of it.

So, i was a running joke.

some kid i'm actually 27, show's how much you know, I drive a scooby needless to say but I just joked about having a skyline, know I have one though, 1/10 scale tamiya TL-01 with the gtr body.

Dude, how about I just put you on my ignore list.

Theres a fix..... maybe even a car in New Zealand has them / it... that kind of stuff...

but at these super high levels ---- everything can only last so long..

The issue with the 2.8 is that the overbore---the walls get thin- you are better staying with a stock size piston.... or stockish - to keep the cylinder walls thicker.

Thicker is better - just ask her....

[SkylineUSA]

Stroker kits and high HP RB26s are not a good match.


More cubes is better for torque, but that is not where the RB series makes its power, its the ability of the engine turning higher in the rev range for hp, kind of a draw back for the street.

I believe the Mine's R34 GT-R V-SpecII has about 618-625hp at the wheels so you weren't off by much. Thats pretty monster power with some relatively small turbos. Yeah the GT2530's are pretty good for the track

I haven't heard of any fix yet Sean. The Croydon team went back down from 2.7 litre HKS stroker kit to 2.6 . So far all seems good but as discussed once you bore the RB block to achieve 2.8 litre they weaken. That is a given.

Ir-regardless 1,400 hp out of small displacement engine is an achievement in itself.
