I ran meth on the street on my supercharged E36M3 and continue to run it in the street in the same car that is now turbocharged. I also run meth on the street in my naturally aspirated E90M3.

Usage depends on how much time you spend above the meth trigger point. Ideal trigger is load based. Aquamist uses injector flow to determine load, and starts spraying progressively. Mine is set to start at about 40% duty cycle. I drive each car 6-7k miles per year and don’t drive like a hooligan all the time so my meth usage is low. I buy about 15 gallons a year. Diluted 50/50, that’s 30 gallons I spray.

I know people who track their cars and go through almost a gallon of mix in a 20 minute session.

here are the comments from ESS' website regarding meth

We recommend the Snow Performance Stage 2 system using the #5 nozzle set to 3PSI start and 7PSI full gain. Torqo or VP methanol is recommended

I like the Aquamist more than the Snow, and I like systems that are load based rather than boost based. But if ESS has found something that works, it should be fine. After all, it designed and tested the kit. The #5 nozzle is small at only 375ml. I flow way more than that in my turbo E36M3 and my naturally aspirated E90M3.

Sweet MCB car up there!!

don't think one is really quitter than the other but I will say I prefer the whistle of the g1 over the v3 cog sound. Need to hear that g1 on a 90mm pulley

It's a significant difference in person.

[ES BMW]

That's a much nicer tone. Almost complements the S65's natural sounds.

G1 Comparison runs on ACN91 w/ 96.5mm pulley and 93 octane w/ 94mm pulley.

what's the difference in boost level between the pulleys?

96.5mm (91oct) pulley ~6.5-7.0lb
94.0mm (93oct) pulley ~7.0-7.5lb

Question for you, I’m buying the G1 system in a few months. I’m currently running the Proflex Commander to run full E85, its just a plug and play system, the product works great and never had an issue with it. The company just came out with a new Commander Pro for forced induction or 600cc/60lb/hr or larger injectors. Whats your take on running this with the supercharger and the 94mm pulley ?

Pressure isn't the problem, it's volume. VT3 systems in the past that have run 100% E85 required custom fuel setups including full fuel line replacement/modified fuel rails as well as high volume fuel pumps.

With the 96.5mm pulley, you dont think the plug and play system would run properly. The system is from Advanced Fuel Dynamics

Not sure, we haven't used full E85 on supercharged applications.

It’s the fuel pump capacity that may be an issue. It might be ok in a 3rd gear run to redline, but should you one day decide to run 5th, the extra load could make it marginal and in the heat of the moment you might not be watching your AFR gauge if you have one and could melt the motor. There have been some posts about superchargers and the E85 kits you can search for.

You might also learn from older posts about how the pump was marginal on the VT3 kits that made around 700 rwhp (built motors) on pump gas. That might be 20% more power than you will make but E85 uses about 30% more fuel.

Anyway, it’s no fun melting a motor. I melted the motor in my supercharged E36M3 (~425 rwhp and ~340 lbs rwtq) in 2009 racing a GTR. We were dead even to 155, when the AFR went lean and a piston ring land broke and part of the piston melted. I had experienced no problems in redline runs in the lower gears but had never run that close to redline in 5th. An S65 is a much more expensive motor to ruin.

In for group buy

I'll have a write up done soon on full E85 on sc m3

[derrick]

I want one!

[tom @ eas]

Have a handful of G1 kits on the road already, 2 more as of last week. Some more component shots of the supercharger unit.

There is a big difference in the numbers ess dyno and eas dyno of almost , 40 to 60 hp for g1 kit using 94 mm pulley,
Ess said 505, and eas dyno 576? I know possible different cars and dynos, but are someone
Modding dyno numbers

Supporting mods like catless X-pipe and more octane, as well as overall engine health will make quite a difference.

what are some of the tradeoffs using the ESS supercharger on a daily driver doing about 8k miles a year? increase fuel consumption? reliability? 93 min fuel rating? I'm curious to hear from people who have lived with ESS for a while.

[bvrider1]

I have had mine for some time. You will need to do more spark plug changes which you can search to see what the interval should be.

Belt changes and super charger oil change is indicative. I don't track gas mileage , this is a V8 that I drive hard.

It is fun every single time. I see you have yours as a daily but that is not the case with me.
