I agree...except for the small shot of nitrous thing...use a BIG shot

2 Garrett ball bearing chargers, 2 external wastegates, 2 stages of nitrous...all good things come in pairs Except headgasket kits...need to suggest that to Cummins

I could build a real set of twins for that price and it would still be laggy since we don't turn the R's of a gasser. Maybe a bigger pully to up the gearing but I would rather not have to worry about another belt at that price anyway. I can buy a used supercharger from an xterra for 300 bucks and a new one for 500. Thanks for the idea but not feasible in my mind.

 

Now thats what I'm talking about!

So it would be like an afterburner then eh? Maybe not exactly because this process still happens inbetween the compressor and turbine stages, more of like adding a burn can to it. So in essence compression, ignition, ignition, exhaust. My q is that the common theory held is that drive pressure is what kills the head gasket, this will ease cylinder pressure on the compression/combustion stages but would add to the drive pressure, no?

 

This is my plan to get more air in my engine, I was going to get a constant speed prop but like the simplicity of the fixed pitch.

 

500 cfm is for pansies why not 1,000,000 cfm.



size: 10’’-98’’ cfm: 1,000,000, static pressure: up to 60’’

 

Thats got to be the worst photoshopping I've seen in a while Mr Nasty

Nitrous in the exhaust manifold does sound interesting, but dunno why you'd want to add fuel there

 

Yeah well I'm feeling kinda lazy right now. So lazy I called in sick to go fishing tomarrow.

 

Ph4tty,

Adding the nitrous and the fuel in the exhaust before the turbo creates pressure in the form of a fire (combustion) that wants out and basically explodes through the turbo vanes wanting to get out. In turn, this spools the turbo quicker than you could ever dream about doing it with the engine alone. The best part is that the stress is on the exhaust manifold and not the engine. If you tried to dump enough fuel and nitrous to the engine to spool the turbo as quick as just injecting it to the exhaust manifold does, you'd probably leave your crankshaft on the ground beneath the truck.

 

When you say fuel are we still talking diesel?

How would compressed air work in the exhaust manifold? Might be an easy way to get free boost

 

some of the old racers shot a charge of compressed air across the turbine wheel of really big chargers to get them to light. i also have heard of running co2 into the intake to cool the intake charge.theres also the air to water intercoolers were you can run ice water threw them to really cool the air charger. cooler air makes for denser air wich will make more power.

 

I would guess that any fuel would work, but being that diesel fuel is already on board that would be my first choice. Nitromethane might be neat if you could get it lit and keep it lit.

I was talking to one of the guys about the compressed air, and it seems to me that they said that it might tend to oxidize and embrittle the turbine blades but I am not completely sure of that because we were also talking abot compressed oxygen and that may have been the oxidizer. Bottom line was that they said the Nitrous Oxide / Fuel combo worked far better than anything else.

 

Hmm.. It would be neat to try something like propane injection just ahead of the turbo like that. Youd really want to start out small rather than pop the exhaust studs or float a valve from the pressure. Sounds risky

 

How about some nitrogen? Doesn't oxidize, readily available, doesn't support combustion (so blowing you manifold apart is less likely).
