I saw it on SYFY. Fuel pumps explode all the time. Now injectors, filters, lines, FPRs, those wont blow up ever. And fuel pumps wont blow up if they are in the back, even in a rear-end colission. Thank goodness Hyper is around to help us.

I sent Hyper a text message asking him if that thread was for real, he hasn't replied back......

What's really bugging me is that I'm 98% sure that he had a water injection kit on his old silver NA.

Or maybe you don't understand what methanol/ethanol does. It's LESS volatile (HIGHER octane rating). It raises the detonation threshold not by reducing the temperature of the charge, but by raising octane (and adding a bit of oxygen to the mixture as well).

Funny you mention it, that thread's been pretty dead recently: http://clubroadster.net/vb_forum/sho...d.php?p=519298

The supercharger set up he used to have will be rusting for years to come.

1.8 Protege Motor Turbo ? Non GTR version (All Japanese Engines, Miami, FL)
BeGI T3 exhaust manifold with external wastegate
Custom BeGI custom Intercooler with (2) 7.5 inches Spal fans
BeGI Intake Manifold
TiAL 38mm Wastegate venting to atmosphere
HKS SSQBOV
Ebay insulation gasket from Precision Motorsports
Miata Link computer
T3/T04 Turbo .48 exhaust side
Greddy Manual Boost Controller
FMII BeGI/Custom Intercooler pipes
Upgraded Intercooler clamps from Turbonetics.
Unorthodox Racing Cam gears (intake cam is slighty retarded)
Flyin Miata Happy Meal Combo
Clutch Type LSD
6speed Tranny (just installed as of 02/02/2007)
3 inch downpipe from Racing Mazda (I bought it from another miata owner.)
3 inch exhaust with Magnaflow mufler
Flying Miata dual feed fuel rail with custom stainless steel lines
550cc RX-7 High Impedance injectors (plug and play to factory harness)
Magnecor 8.5 mm cables.
All water lines have been removed and upgraded to stainless steel lines.
All oil lines have been removed and upgraded to stainless steel lines.
Turbo return line has been upgraded to stainless steel line.
Moss tranny brace to prevent missing gears.
1.8 engine parts (oil pan, 2001 windage tray, motor mounts)
1.6 alternator, water pump pulley, and crank pulley.
What is left to do:
1. Find a set of good drag radial tires.
2. Buy a new carpet
3. Paint the car
4. Alcohol injection
5. Upgrade the oil cooling system.
6. Upgrade the suspension.
and.......Maybe get rid of the A/C

Volatility is how well a liquid vaporizes.
Ethanol/Methanol have higher volatility, so it vaporizes better, thus reducing the temperature of the charged air.
Although Methanol/Ethanol have a higher octane rating, they are actually more prone to preignition, this isnt a problem when running on pure alcohol like they do with drag cars and whatnot, but it is a problem when running on gasoline because the preignition can stimulate detonation. This is why youre not supposed to run pure "meth" injection, because if you inject enough the tendency to pre-ignite will overwhelm the lower IATs.
This is well documented in "The High speed internal combustion engine" written by Harry R. Ricardo, who was pretty much the founder of water injection as we know it today.

Well there you have it, he's a douche bag.

Heat Capacities:
Water (liquid) = 4.1813 J/(g*K)
Water (gas) = 2.080 J/(g*K)
MeOH (liquid) = 2.48 J/(g*K)
EtOH (liquid) = 2.44 J/(g*K)

Being a chemist I can vouche for this assessment of volatilization. The water is mainly used in conjunction with the alcohols as it has a relatively massive specific heat capacity to other solvents.
Heat Capacities:
Water (liquid) = 4.1813 J/(g*K)
Water (gas) = 2.080 J/(g*K)
MeOH (liquid) = 2.48 J/(g*K)
EtOH (liquid) = 2.44 J/(g*K)
Heat Capacities:

MeOH (liquid) = 2.48 J/(g*K)
EtOH (liquid) = 2.44 J/(g*K)
Now the bit about pre-ignition and whatnot I have mixed feeling about.
The source is very reputable, but also very old.
And so many people are very successful with E85 which is a mix od petrol and ethanol.
It may be possible that there is a very strange relationship between concentration of ethanol and detonation. Which would make sense because it is a balancing act between IATs, octane, and detonation threshold.

What's the difference being in the trunk, frame rail, or anywhere else? A fire can happen regardless of it's location, but a grenade it is not. Mythbuster's even had an episode with this very scenario.

There was a time when he was a sane and sensible person. Long time ago though.
And I'm very tempted to fulfill your request.
