crazy question

  

Zellanor -> crazy question (1/18/2007 6:08:16 PM)

I know this mite sound like over kill, but can you use Nitrous and run a turbo or S/C?

Yes, and with using nitrous it can cool down your engine when running a supercharger, not sure about turbo. I'm sure some one will chime in.

thanks

I've heard of quite a few people using nitrous to help spool up a turbo faster!!!

Zellanor -> RE: crazy question (1/18/2007 6:29:54 PM)

NOT TO BE A DI-K, BUT CAN YOU SHOW PROOF? JUST ASKING

Im talking from no experince but i would think that alot of forced air into the motor and would play a role in shorting the life of are motors.  From what ive read are motor stock internals can only take so much...a turbo/sc plus nit sounds like a bit over kill.

Running nitrous with a turbo is usually used to fill the gap of turbo lag. It can be done, but is risky if you use the nitrous during the turbo's full boost. The increased risk of predetonation is very high. As you are probably aware predetonation can kill your motor. If you don't like turbo lag then don't install one then try to cover the lag with nitrous, it is too risky. Instead, use a supercharger. Superchargers will develop boost at much lower RPM's especially twin screw and roots types. Using nitrous with one of these is pointless as they can produce well enough power on thier own. Kenne Bell's twin screw can be cranked up to produce 800+ HP. Your stock engine block can't even come close to handling that power. The stock 4.6L shouldn't be pushed past 475-500 HP. Even at that rate it's life will be shortened. All being said, it just does'nt make awhole lot of sense to squirt your street motor if you have forced induction. Let the 1/4 mile track cars take those kind of risks, your motor will thank you.

Get a hold of the book called "Turbochargers" by Hugh MacInnes, published by HP books.  It's a little dated in that most of the specfic models of turbos discussed in the book are now obsolete with much better ones available, but the theory is solid.  This book mentions nitrous used in conjunction with turbos, as well as multi-stage turbocharger setups.

jerjan is right, nitrous is generally used in conjunction with turbos or centrifugal superchargers to fill the void in power before they really kick in--and only in drag racing applications.  Once the blower/turbo kicks in you don't need the gas.  Also, screw blowers or roots blowers make good boost at low RPMs and have no lag so nitrous is generally useless there too.

BUT, if you want to get really crazy, NOS makes a nitrous manifold designed to fit under an 8-71 blower!  The 8-71 is one of the classic musclecar superchargers.  It's a roots style unit...very common to see on chromed out hot rods and old school muscle cars that have been modded.

If this is going to be your "race car" go ahead and take the risk and spray her but if its your DD or a car you like being able to drive on the street. Then i wouldnt because theres going to be quite a few monday mornings youll be calling for a ride to work .

mygt500 -> RE: crazy question (1/19/2007 5:36:18 AM)

I agree if you drag fine and don't mind rebuilding the engine in the near future!

RED121572 -> RE: crazy question (1/20/2007 8:11:57 AM)

I agree, you can run two power adders at the sametime. Ive read nothing but horror stories from doing that, though. [:D]
