To the Tech Gods

a predator, sct, or any other handheld tuner... so 250-400 bucks depending if you go new or used... and I strongly suggest new as used stuff isn't covered under a warranty.
 
new tune to supply enough fuel and remove the 6250 rev limit

new stronger valve springs. that's all i can think of off the top of my head. i'm sure there's a few more but there's really no point




as far as revving to make power, we're talking major cash. new or p&p heads, lumpy cams, new intake setup, full exhaust, complete fuel upgrade, tune, lightweight flywheel and driveshaft, we can go on...
 
I know someone that has a cammed/bolt on/nitrous GT, 100% stock internals and has revved it to 7200 rpm as set by a Diablosport tuner.

He did this a few times and the engine did not blow up.

Well, if you hit that rpm for a sustained amount of time, something is sure to break (on a stock motor). Then again, the thread starter is asking about 8 to 9k, which is a lot more.

No doubt at all on that. I told him he was pretty crazy for revving a stock NA 2v that high, let alone with alot of bolt ons, cams, and spray. But... hes done it, still runs like a beast. He has backed the limiter down since then.
 
What would it take........how costly is it

It would take the following, minimum (more than I'll list probably), to even concieve of a non honda-VTEC engine to rev to 8+RPM's without blowing.

Making things like the driveshaft and such lighter so the engine doesn't have so much stress on it when it's spinning that fast...

A totally built top end and probably a fairly well built bottom end, valvesprings, valvejobs, probably notching the pistons for more peace of mind to avoid PTV contact, opening up your coolant ports to allow the engine to cool off after revving that high to prevent some internal-welding from happening.

And a tuning device (dyno, handheld, reflash??)

It wouldn't be worth it by any means, and most definitely not economical.
 
I think you can go about this 3 ways:
1. Rev that high and blow **** up (no upgrades other than a tuner to remove the rev limiter).
2. Rev that high but be way past your peak power. In other words useless. (upgrade valve springs, oil pump, tuner, bottom end)
3. Rev that high and make power. (Above + cams, head work, and some stuff I'm probably forgetting)

are you trying to immitate f1 cars? the reason why their v8, v10, v12 whatever they have can rev so high is because they have an extremely small displacement in relation to the amount of cylinders.

make yourself a 2.0 v8, with some 4.56 gears, and have fun :D.
 
oohhh.....hahahaha...i asked this question mainly because the sound of a high revving v8...is like heaven to me...just was wondering if it was possible with a mod engine....soo...i gues this would be a project for the ppl with more money huh?...
alright well thanks for the info....u guys really now ur *****..hahaha

There are a lot of high revving modulars out there, but they have done work to the valvetrain. There is nothing inherantly characteristic about a modular motor that doesn't allow it to rev high, it's just like any other motor, you really need to upgrade the valvetrain to make it more stable and durable.

But like mentioned above, with the stock heads/cams, you stop making good power after 6k RPM's usually.
