Highest amount of boost

[Noremac]

subject says it all.. what car/setup and how much..
I've seen dyno charts for an ls-vtec boosted at 29 psi making 647 ponies, but i think thats the highest amount of boost ive seen.

Go look at the dyno vid of duc's car on groundzeromotorsports.com, I think it's his 700 WHP vid. Top fuel cars run 40+ PSI, as do diesels, and i've seen a few supras over 40 PSI. What exactly do you want to know.

i forget to mention.. honda or acura cars only..

Also, what type of forced induction do you want to know about? Boost from a turbo and boost from a super are two different things and can't be measured equally.

Also, boost doesn’t completely equate horsepower, airflow does.

But why, are you really gonna do anything like that or are you just filling up space with lame questions?

Supercharger or Turbo, either one..
And i never said that it did equate horsepower??

Don't mind any negative comments. We're just trying to figure out why you want to know how much boost you can run and how much horse you can get.

Do some research on what your LS block can do. If your internals are forged, you shouldn't have a problem running on 20-25psi. You'll probably get anywhere between 300-450hp...not whp, mind you. No matter how many ponies you motor makes, you'll never get them all to the ground. If you're talking supercharger, make sure you have eveything you can cram into your car to help keep that engine cool. You don't want to race an M3 and blow your motor, right? If you're talking Turbocharger, re-evaluate what you want of your car. If you're gonna run 20psi on a daily driver...I hope you love rebuilding your engine every 30k miles. The bad thing about turbo's are how hot they run. True, there are things you can do to prolong your turbocharged vehicle's life, but you're poisoning/overheating your motor evertime you run over 10psi. Keep in mind, a turbo is feeding your car's exhaust back through the intake. If you can smoke a whole pack of Marlboro Reds while running 2 miles and NOT collapse, boost up! But if you can't do it, don't expect your car to do something comparible. Engines (like humans) NEED fresh air. The more psi you boost with a turbo, the less fresh air your motor's getting, and the more likely it is that your motor will blow.
Don't get me wrong. If you're car is going to be track only, and you have the money for frequent rebuilds; Turbo all the way! Go ahead and boost 28 or 30psi. But if it's your daily driver...consider a supercharger or Nitros if you really want to be force induced.

Either way, it's ultimately your call. A lot of people find turbochargers very rewarding depsite the higher maintains requirements. I'll be the first to admit; the sound of a blow-off valve...I get off on it. Something about it gets me ready to drive to the death.

Do your homework, and findout for yourself what you can and what you don't want to do with your car. Good luck on all your decisions.

someone please explain to dark eternal how a turbo application works. im trying to do my math homework and really don't feel like writing a long post, thanks.

sorry, got class....

darketernal, just read this....

http://auto.howstuffworks.com/turbo.htm

and please dont try explaining something if you are not ABSOLUTELY POSITIVELY SURE you know what you are talking about.

DarkEternal... please... step AWAY from the turbocharger! you don't know the first thing about them...

Listen... if you really are asking this question as far as how much boost a honda motor can handle just do a search in this forum, this topic has been brought up before... but to put it short if you are wanting to run good amounts of boost look into rebuilding your block first cause not only will your stock internals eventually go but your aluminum block won't last too long either and you'll not only be needing new rods, pistons, etc but also a whole new block (obviously depending on how much boost you run, more boost, more damage)... anyways do a search in the forum and by the way you asked the question it seems you're wanting to run serious levels of boost, look into internals first.

can u be suprized he uses mainly APC products after reading his post?

hey guys, i personally am not wanting to run boost. I was just wandering if there was anyone on this board who was running really high boost to see what kind of setup they were running.
