I have no intention of reclaiming the steam. Is a far easier thing just to vent it. The excess bulk will consist of: water tank, 1lb, plus weight of water. Probably won't need more than 5 gallons. water pump, 5lbs oxygen cylinder and regulator, 30llbs combustion chamber, 4x12" tube...

Still pondering the idea. I don't know why I didn't say it initially, but my temp idea was off. Rather, the hotter, the better. It's all about VOLUME through the turbo, not mass. At 1500F, steam has about 57% more volume than air. It gets better the hotter you go. To get the steam hotter, you...

Equations disgree completely. Those equations make pressure and volume change across the turbine the opposite of the data I found. Your math suggest 10x the pressure only produces ~4x the work, is this right? Seems counter intuitive.

You email me the info on that group perhaps? Maybe they will let me in, I'm sure I add to the discussion.

A compressor moves a certain VOLUME of air. Even though most compressor maps list airflow by mass (lbs/min), it's actually a matter of VOLUME (CFM), that has been translated to mass by assuming a certain temperature and pressure (~25C and 1 atmosphere). So, what this means is that a...

Yes, it would. You would need some means of controlling the vanes. Obviously, the stock ECU can't do that. You could adapt the AEM EMS for a Buick, which is doable. The Gen VII DFI and/or the FAST system might have sufficient features, not sure.

JDEstill, sure I can program it that way, no problem. There really isn't much I can't do with the EMS. It has simply amazing adjustability in it's boost output. I'd probably have it set to have the vanes wide open at low to mid vacuum, and close them down as I approach 100kpa (atmosphere), fully...

I'm fairly certain the vanes are controlled by a simple PWM signal to a special solenoid (called the "VGT solenoid," I have the part #), which then connects to the turbo. Since the AEM EMS I am using as the main fuel/ignition computer has a fully programmable 3D map for the duty cycle on the...

Picked up a couple VNT turbos off of Ebay. They are GT3782VAs, the turbos on the 2003+ Ford Powerstroke Diesels. Each can support up to about 575RWHP. Gonna slap one on my Supra and use my computer (AEM EMS) to control the turbine nozzles. Will see. Thought I'd let you guys know. Buick...

6 lb/min usage is acceptable. That's over 3min of full boost time per 20lb cylinder of CO2. That's double the amount of usage time the methanol injection I was running, which I didn't bleed dry even on long trips. 700RWHP means when you use the power, you can't use it for very long until you are...

This is a theoretical question. Please don't tell me "Don't do this," I know. The actual "work" done by a turbine is determined by the pressure ratio from the inlet to the outlet, and the mass flow through it right? In looking at Turbine flow maps from Garrett, I think another principle is...

You are looking for a liquid oxidizer. Liquid nitrous basically. I have done lots of study into this. What I came up with is Nitro is a BAD idea. It's a very knock happy compound. VERY. Even a little in the cylinder has the potential to pre-detonate badly, and when it does, that will in turn...

Well that's interesting. Nothing but CO2 eh? I supposed that would work, but would require a TOTALLY different approach to turbine design. You would want a super small turbine wheel and housing, with lots of tighly packed fins. You would want tons of backpressure in the entrance to the turbine...

Well shot down the proportional valve idea. #1, the things are too damned expensive ($500 for what I need). #2, converting the injector signal is much easier said than done. New idea. Liquid propane injection through a single injector pointed at the throttle. Problems, solutions: 1. At...

I think the whole propane=lower power thing is a result of implementation, not the properties of the fuel. By my calculations, you should at least make the same power, more likely more power, if the AFR is controlled as well as it was with gas, and the timing is maximized to run with the...

Could you post the name of that company? The main advantage IMO of full time propane, is that you would need only one injector at the throttle. No need to worry about fuel distribution when the fuel is already a gas.

This is a little idea I have been bouncing around my skull the last few days. Goes something like this. Turbo is no longer part of the exhaust. Exhaust would be like a NA. Turbo is powered only when needed. Sits idle most of the time. Power to spin the turbine will be provided by the...

Knowing for sure allows me to calculate ahead of time how much pressure drop I will see, given a certain boost, CFM, and temp. One place said they are rated at the intercooler. Haven't asked Spearco yet.

Hopefully someone here can clear this up for me. Let's take the Spearco 2-170 core (2-230 assembly) ratings as a example. This will (at least initially) only address the determination of pressure drop, without covering efficiency (how much cooling occurs). CFM PSI Drop 700 .18 1100...

Yep, a real threat to society that one. :rolleyes:
