Methanol, Good or bad with water injection
My Fd is in for mapping next week, A long spec list but its a single Turbo set-up, ported etc etc------ I already have a water inj kit fitted but are wondering if theres anything to gain running a water-methanol mix?
If there is i suppose now is the time to put a mix in the W/I tank ready for mapping.50/50?
Reading some of the water injection forums it seems the way to go, But with a rotary?????

only use the meth/water injection as a safety measure, never tune WITH it.
the benefits are decently good IMO, more resistance to detonation/knock, cooler charge temps, and keeps carbon buildup to a minimum. pretty much the same benefits on a piston motor...

Why not tune with it? There are members using an 80/20 mix (100% methanol) making insane numbers running way more boost than just gasoline could. I don't see a problem pulling out gasoline from your maps with a reliable system, it's been done and proven.
Check out the auxilary injection section of the forum, there's a wealth of information.

I'm a T2 guy, running 50/50 water/meth and use it with to tune. My tuner will only tune aggresively if you have meth.
Meth IS a fuel. and it REALLY cools the intake charge.
These are the two main benifits over water. Meth will probobly add about 50 hp as well.

Adding meth, its a octane booster/fuel so adding it will bring the AFR down?

Jason....how much is the kit you recommend and how much should installation cost if you don't do it yourself? I was told everything should cost about $400, but is there additional options you might want to do to keep it it safer.

And the Revolution...
Exactly the reason you should use quality components when doing this setup. As far as meth setup, BUDGET should not be in the description. Use good/tried and true products and it should work well. And as far as tuning goes, if you're not sponsored or know how to rebuild your own engines, or are rich then you should never tune on the limit. There is an a great tune and then there's on the edge. What I'm trying to say is proffesionals can run on the edge, I'm poor (because of this car) so I will not run such an aggressive tune on my stuff. Fortunately we have a lot of folks that are doing the research and testing for us so that we can learn from those mistakes.

i suggest that anyone who wishes to know how AI is actually being used visit the TurboBuick board's relevant section.
currently their are 76 PAGES OF THREADS containing 3008 THREADS.
mostly all have to do with tuning for POWER. along w low knock...
it's all there.

Buicks you say? RX7s plus AI= 20++PSI on pump anytime you want it with low knock.

AEM just released their alky kit a few days ago which has some safety features in case there is an issue with the system. Plus it doesnt cost a lot.

Install usually takes a few hours depending on where you mount the tank. Most shops would probably charge $300 to install it.

If an alky kit fails you are right, you're screwed, but failures are very rare and I dont think I have seen one. Most Meth systems are not used as a safety feature mainly because it causes a very rich condition when it kicks in. I have tuned a car that was running 11.5 AFR without meth and dropped to low 10's with meth. The majority of people will tune with it.

Just run 100% water, do a search for my user name for posts in this sub section and look for the info there is alot of it spread across many different cars.
Right qty of water and 2 bar boost is easily handled on pump fuel, the power well again i am not sure if anyone has matched what i have achieved reliably on pump fuel??? either way all the info you need is here.
If your concerned about failure or want to switch the system off when runing another petrol based fuel type then pure water is the only way to go period.
