How the hell does Exvitermini.com make their Skyline redline at 11,000plus rpms?!!

Hello guys:
I took a visit to that guys site and he built a skyline engine that can redline at up to 12000+rpms but the redlines at 11000+ rpms because the drivetrain couldn't handle the rest!! That is amazing to me. The continuous improvement and surpassing of limits. He must break a lot of **** doing this.

Now I know that DynoFlash can redline at 9000 rpms because he has the Ferrea (did I spell that right) valve springs and other motor modifications, but our engine is only 2.0 liters (a little less if you want to get technical) so it should be easier to increase its redline since of the lesser rotational mass. what is the possible limit? 11,000? 12,000?
I just think it would be fun race someone and not have to shift as early. Would it be necessary to change other things in the drive train to? I also i drive hard and fast all the time and it would be nice to do it with redlining all the time which would increase the life of the engine.
Take care, people
Omar

It's called money. I have seen other cars rev that high but it's useless if it's not making power up there. Hell I have driven a Rx-7 that reved to 13,000 but it mad no power after 9k

True on the money and true on the power. That was going to be my next point. Your going to have to get some speacial cams that make power after the 7 or 8thousands.
But of course it takes money. I just wanted to know what kinds of things does that money buy.
thats awsome on the rx7 but I don't understand why it wouldn't make more horsepower.
peace
Omar

All around lightweight, balanced and stronger EVERYTHING: camshafts, valves, balancing out the crank (maybe even knife edging it), heavy duty lifters and springs, newer/better rod bearing and bolts etc. Theoretically, a rotary though can have an unlimited RPM ceiling, granted, the hardware can back it up.

It would be *** kicking if Mazda makes the next generation FD rev to 10K. That would a badass car to street race. I wish the EVO come stock with 9K rev limit. That is why i love the s2k so much when I had it. THe rev limit at 9K is so much fun. peace..

At such high rpm, it becomes almost impossible to feed enough air to make more power. You have to enlarge the whole intake part of the engine and the cam to open the valves longer to get more air at higher rpm. But, you lose low end power and it would be difficult to drive daily.

Its called being Australian

also, theres no wastegates, no boost controller, he has shoved a dense amount of money into it, and he's not even far from finished.. the engine can handle over 3.4 BAR OF BOOST !

He's ultimate goal is to beat the HKS R32 and be the quickest 1/4 mile GTR in the world.. atm hes around 3-4..

Also his man goal is to be the quickest on Street Legal tyres, which Veilside is winning atm..

We have alot of info on this car in our aussie import mags

Go Mario !!

Hey if you have enough money it seems that anything is possible. Formula 1 cars have small V8's that rev to 18,000 rpm.

The rx8 will wind up to 9500 stock, once we get into the motor and ecu it should be around 10,000-10,500. The rotors in a rotary motor only spin at 1/3 on the shaft speed so it allows them to rev so high.
