Auxillary Injection

Post by jimmacsrx7 » Fri Sep 18, 2009 9:13 pm

I have a question as to Ai.Specifically water/methanol injection.Is it allowed? I am interested in the benifits of making a turbocharged car a little more safe under boost as well as hp gains of being able to add more boost.Thanks,
Jim McNamara

I believe water injection is legal in Prepared, meth no.

meth injection dosent add power it accualy takes power away and wat it dose is lowers cylinder temps allowing more timing and more boost thus more power so it depends on how u look at it

Water/meth injection increaceses the octane rating allowing huge increases in boost in turbo/supercharged engines. Under the current rules NOS isn't allowed in any class. So why should W/M be allowed? I don't see the difference.

We have had an SPB car running meth injection for a couple of years now. No one has every questioned it. That said, I think it should NOT be allowed in Street Prepared classes as the gains are huge!

It's just a little windshield washer fluid... :wink:

wat it dose
accualy takes power away
Indy cars run pure methanol, you'd think they would go backwards with such a huge power loss! :)

I think one concern is that the a flammable methanol or mix be treated like fuel with appropriate plumbing and tanks etc. Tanks should be behind a firewall.

Normal street gas has up to %10 alcohol and there are many aftermarket fuels available, so I'm not sure policing fuel is going to be good for the club or easy to do. I don't think the size of the gains are a big factor in the decision, especially if the changes are relatively inexpensive. Actually I would argue the opposite, inexpensive performance mods are a good thing, We typically spend too much modifying these cars.

I'm using windshield washer fluid injection to prevent my motor from being destroyed by overheating as happened last year. When I ran on the dyno after installing this mod, I saw no HP increase - because I was already running high octane gas. The water/meth injection is purely a safety measure.

SP is supposed to be for people who don't want to put up with the candy ass ST rules - so leave us alone! If you want to spend your time figuring out ways to slow other people down, go bitch at the guy who wants to run 5mm spacers in SS :lol:

There was a rule proposal to allow meth injection in SP/P either last year or the year before. If I recall correctly, the use of pure meth was not allowed.

Methanol is an extremely toxic substance. Exposure to your skin and/or breathing in vapors can cause major medical problems. It is also extremely flammable, and the thought of a plastic methanol-filled tank triggered safety concerns for participants and corner/rescue workers alike.

For what it is worth, I have a water injection system (Aquamist HFS-6) on my street car.

Pure water is good enough for WRC cars!

And by the way, in SP and P, there can be no motions to "allow" modifications - only to "disallow." That's because the rules are written so that if it's not specifically stated in the book that a particular mod is illegal - then it's legal.

Concerning the supposed toxicity of Methanol, I guess we need to ban all windshield washer systems.

Regarding methanol vs. nitrous, they're TOTALLY different. Nitrous oxide is an oxidizer, not a fuel. Basically, it radically supplements the amount of oxidizer in the intake charge, allowing (REQUIRING) you to burn a LOT more fuel and make a LOT more power. Methanol is just another fuel. Without other mods, it doesn't by itself allow you to make more power. But it will allow you to run a lot more boost pressure and/or compression ratio, and this secondary effect results in HUGE power gains in a high-pressure turbo engine.

Anyway, good to know I have a "protest" option in SPB!

Do I need to put a :D at the end of every sarcastic comment I make? Of course it's ludicrous (no offence, Will) to think that windshield washer fluid is a safety hazard. But my main point is that there is a fundamental difference between the SS and ST rules on the one hand, and the SP and P rules on the other. If anyone is still confused, see my post above and then go look at the rule book.

I did a search on "methanol" in the rules and found no mentions of it.
Making it illegal in SS/ST, and legal in SP/P.

So I guess I don't have a protest option for the Halloween event after all :evil:
