i am looking to build a non vtec b series motor that will rev up to around 10k is it possible to build one that can rev that high even

 

The question you need to answer is: Do you want an engine than can rev to 10k and make no power or an engine that'll rev to 8500 and make power? What's more important RPM or power?

 

^^^the rpm...duh

 

It was a retorical question.

 

never mind i will figure it out it has become aparent that not many people have experience in doing this to a motor not to be rude to you i will just have to goto a more specific site

 

There's a reason why not many people have the experience you're looking for.

1) Those that do, hide from the site after they blow thier motor and don't want to look stupid.

2)The people who make power know that reving to 10k is pointless in anything other than an all out race car.

3) Anyone that wants to rev that high knows they need to do it with the appropriate motor and it's not the one you're talking about.

Good luck.

 

00Red_SiR why try to answer this nonsense. You offered a hand and they slap away.

 

OP, it is easy to build a engine to rev to 10K but why?

 

i did not slap away i did apologize for seeming rude and i am glad to get input from fellow h-t members the reason behind doing it is because how many others out there can say there motor is built for those rpms

 

Who are you trying to impress? High RPMS don't equal power or torque.

 

i am not tryin to impress any one i know that rpms do not equal that i do not care what other people think i just do not want to be like everyone else and what part of pa do you live in cause i am from pa my self

 

The only way an N/A motor is going to make power is through revs... i don't care what anybody has to say, its a proven fact. Now; there are not that many that know how to do it that way since the available aftermarket parts are design for your average 8.5k joe. Why you think there are so many 4age owners destroking there motors??

 

why stop at 10k? I mean, remember the mac 11? Let's have the fastest cyclic rate as we can possibly achieve. More is better right? Let's waste bullets, wear our gun out faster and still not be able it hit anything. I think it would be more realistic to build a nonvtec b for usable power. That is the point isn't it? To make the car quicker or faster? There is no reason to rev a nonvtec b to 10k other than to say you did it. It won't make your car faster, or your transmission happier.

 

i am sry but i do not care why it is a bad idea or not i want to do i am going to do it one way or another so unless you have helpfull information that can help me achieve my goal do not bother posting because you are just wasting your time trying to change my mind

 

The main bit to make power at higher revs, (this was told to me buy the fella who will be professionally building my engine) said, that in order to safely make horsepower at higher revs is first to balance the bottom end in order to keep your **** together at 10k, then you need to do the head work and really get in set with a good flowing intake, throttle body, headers, exhaust, cams, valves, springs, port and polish, pistons (higher cr), proper tuner, holy $#!+ am i forgetting anything?????

 

You can rev to 10000rpm and make a broad power band. Spoon cams and valvetrain do exactly that. Now it is about 250 whp from about 8000-10000, all you'll need for a non-drag build. Also check out AEBS, they're B24 revs up to 10000 and makes power all the way up there. This theory poeple have about high revs=low power is not true. F1 makes all of there power(900+hp) above 15000 and peaks at 19000 from a 2.4L V8. It takes extreme R&D to do this, which is why few companies provide such services. You will pay lots of money for 10000rpm, when done at the right companies. Look at Skunk2 pro3 as a balanced option.

 

finally somebody gave the dude some encouragement, if he wants to make a gokart motor hand glider to commute to work, instead of car pooling with his neighbor, help him out. its his will...

when F1 banned turbos engineers turned to revs. everything you have has to be design to make the power band operate at that engine speed. From cams, to runner length, injector placement, rod length, even pneumatic valve springs if you can find them(just being stupid).. go for it. Its true that its going to be a pita and you are better off at 8~ like everybody else is saying, but if that's your will go for it, do your research and have fun. i recommend you to look somewhere else, people on this forum are just like zombies.. they know when you ain't one of them and point there fingers at you.

 

thank you very much guys

 

Yes balancing the entire motor is essential. Not just the cylinders should be balanced, but the rods and piston wieght should match the crank rod journal weight, and a good harmonic balancer along with flywheel and pulleys need to be balanced individually. Small imbalances causes greater momentum at higher rotations causing the heavy spot wanting to break free from the rotation, deforming the material. Potentially hazardous. Kinda like how the land speed record car's wheels are machined billet aluminum to a precise balance, because an inbalance can actually cause the metal to "explode" as explained to me as a kinetic physicist. If you can get the tuner that the builder recommends, that would be ideal.

 

I been thinking of building my b the same way Got it sittin in the barn, I should just send to Cali to AEBS Racing, they have made multiple engines. they website is AEBSRacing.com, check their motor pics, it is sick!!

 

he said non vtec

 

all i know is that i want a 1000CC destroke B16 for my caterham kit

 

ok thanks for your help and all the info

 

To whoever said high RPM doesn't equal power or torque, that couldn't be further from the truth. RPM does equal power . . . horsepower. Horsepower is just a mathematical calculation based on torque and rpm. The formula is:

Horsepower = torque x RPM / 5250

An engine that can spin to a high rpm makes a lot more horsepower than it does torque. An engine that makes 150 ft/lbs or torque at 3000 rpm makes 85 horsepower at that rpm. An engine that makes 150 ft/lbs of torque at 6000 rpm makes 171 horsepower at that rpm. An engine that makes 150 ft/lbs of torque at 9000 rpm makes 257 horsepower .

You see that although the torque output remains the same on each example, the horsepower goes higher the more rpm it spins. So although high rpm, high horsepower engines don't have a lot of torque, they do make a lot of horsepower. Those extra rpm are very useful.

You know how when you floor your car in first or second gear it accelerates a lot faster than when it is in third or fourth? So imagine not having to shift to twice your current redline. This is how Formula 1 engines make their power, and they are very powerful. A Formula 1 engine only makes 225 ft/lbs at peak torque but at 18,000 rpm that engine puts out 775 horsepower from a naturally aspirated 2.4 liter V8.

The secret to their insane acceleration is due to the rpm they run. There are some fundamental changes that have to be made to the engine so it does not grenade itself. These engines have a very short stroke and that is their secret to surviving these high rpm. The Formula 1 engines have about a 4 inch bore, but only a 1.7 inch stroke. Bore/stroke ratio is the single most important factor when building a high rpm engine.

So there are great reasons to do it and Honda engines are perfectly suited to it.

 

i am looking to build one that revs 15k .. what should i do? LMFAOOOOOOOOOOO
