high rpm build

[Satizzle]

what all is involved in getting your engine safely reving up to 8k

i know balancing the crank to 10k, light forged internals....
i guess aftermarket knock sensor would help check it...
and how do you get the rev limiter gone....so far i've been told about the msns

really the only thing to rev to 8k would be a removed rev limiter (ie. standalone).

As far as safety and purpose, the only purpose would be if you ran a turbo set up, other wise power is a major loss after 5500ish. I've heard that valve float on stock heads = 9400ish, so I would say you can do it with everything stock, but then again I don't think that anyone has focused on such a build because it is the opposite of the way our engines were designed.

Ideal and theory would be upgraded valve springs, new valve seals, lightened/balanced/shaped crank, lightwieght internals, lightened flywheel, clevite bearings, and I'm not sure what else would be needed. I wouldn't think an "aftermarket" knock sensor would be needed to run it safely. KEEPING THIS IN MIND, the things I mentioned are just precautions for such a build, not a promise of power or gain in any form. The reasoning for using lightened parts is decrease the total of rotating mass which I guess would decrease the time to reach the higher rpms, and also decrease the amount of stress on the crank at such a high speed.

destroke, destroke, destroke

you could super retard the cams like Jay did too to make power up there

there is a huge thread about this over on TSN in the n/a section, it's got a lot of info too.

shorter stroke And like minivan tunar/spoolinsc2 said, I would take lots of safety precautions in the engine aswell, so that you can revv up to 8k without anything getting damaged.

just wonderin cuz i was readin that the race cams at sda are best in the 5-8k range
i already have a light flywheel and i wanted to go with .40 over, lightweight crank, rods, pistons, and an all redone head from sda or sps

i mentioned the knock sensor just as a precaution to make sure you wern't over estimatin your build

[Satizzle]

i never got a reply from tsn, since you have to be like let in or whatever, i just got the first one that says to wait for another one

[saturnspeed_12]

yeah valve float=EVIL!!! do they include dual valve springs in those performance heads? if not GET THEM!

[Satizzle]

dual valve springs??

i know sps has stiffer springs forget exactly it says about it

but thanx!

smell that maple syrup.....mmmmmmm
a pat of butter too. yummy.

SPS Stage Two High Performance Cylinder Heads

Our Stage Two heads include +1.0mm oversized Ferrea Super Flo valves, Ferrea dual-spring turbo special alloy valve springs, and Ferrea lightweight titanium spring retainers. Each head is expertly shaved, ported, polished, and treated to a 3-angle valve job. Then it is reassembled with new valve stem guides and new valve seals. The result is improved flow and a significant boost in compression (approx. 10.5:1.) Heads arrive assembled (no cams) and ready to install.

yah so i guess it saves about a grand to get the sda head and buy the springs from sms, and you guys probably know somewhere cheaper to buy the springs too huh? there $308 @ sms
