Boost cooler

unreal808 · 04-01-2006

I was thinking about methanol/water injection for the Laser and know someone in the past has tried it on a DSM, my question is what is the current thought about the use of methanol/water injection to help with running high boost?

Methanol injection is great. Water injection is not worth the trouble. With straight methanol injection, you should be able run 28+psi on pump gas and do it with much smaller injectors than it would take on race gas.

hell yes, the GN guys were onto something. guys have run 125+mph traps without intercoolers using the stuff! and by using i mean in addition to gasoline, these are not complete meth only cars.

definetly a very interesting development, lots of pumps, nozzles and safety systems to look into.

Yup, it is the shit, and probably the next purchase I'll be making for my car. You can run 25-30-ish psi on pump gas w/ no problem. Alky injection is a really really big thing to do in the evo scene right now, as it allows all the whiners that are afraid to yank their turbo off & swap it w/ something bigger to do 320+ whp on the stock turbo.

My buddy has a kit for his S4, and one of these days he'll finish getting it installed and I'll be in the dust. So yea, go for it. Snowperformance.net has them.

Yea I like the kit from Snow.

water injection is trouble.

Water Injection is not the same as Methanol injection... Water/Rubber alcohol injection is a waste of time. Methanol injection is like spraying high octane race gas into your car that also acts as an intercooler, it can make a huge difference in the amount of boost that you can run and adds fuel in the process.

Instead of Ethanol, would E-85 gas work for this? Pardon the newb question, but it's just a thought.

**Shane@DBPerformance** · 04-18-2006

Methanol, not ethanol.

Why? Because it cools the intake charge? Or because it cleans the combustion chamber?

If your goal for water injection is to run 5 more psi, then you'll probably be disappointed, but I don't see how it's a bad thing. Maybe not worth the money or hassle like Shane said, but it does have benefits.

I tuned a turbo Honda today that was running straight E85. You burn through that stuff pretty fast.
