JB4 Methanol Injection Testing!

[Mike@N54Tuning.com]

BMS is working on JB4_S55 methanol integration and posted some interesting dyno results of a simple WW methanol kit. The test car was run on E30 + 49% boost juice with no mods other than the JB4 and meth kit. They used the word "staggering" to describe the power and torque gains over the same day baseline. It's hard to disagree I think

You need to shift at 5500 RPM to get the better performance, not that interesting like to shift at 7600, but still the result is cool with everything stock!

This is fantastic!

When you say 49% boost juice...what does that mean? Isn't boost juice already mixed at a ratio of 51% water and 49% meth?

Forgive my ignorance, but can some explain Methanol Injection and how it works with regards to capacity and how often one needs to replenish what I assume is a separate tank?

With my turbo NSX (similar power levels, similar displacement to modded F8X) I have a 1 gallon tank in the trunk. I have used no more than 1/3rd of a tank for a full track day. Some people run it out of their windshield washer fluid reservoir.

I buy the pre-mixed Boost Juice which is 51% purified water and 49% meth. You can save money mixing your own but as long as I stretch a gallon out the extra cost is worth the convenience of not mixing my own. Plus there is consistency using the pre-mix.

With a meth kit that has a controller (or at least like my AEM), you can set the start PSI for it to spray as well as the PSI you want it to reach max at and it will ramp the flow between those. I think different kit makers controllers have different capabilities and may work differently. I know some now have various failsafe features. Mine is a little older and just uses a pump on/off/flow led to indicate everything is OK.

It has been my understanding that the water reduces air temps primarily and the meth provides an octane boosting effect.

Personally, I love meth/water injection. I can run 93 oct pump gas all day long with added safety under boost.

Isn't this worse than the bms e30 only car?

Close... 510rwhp with E30 alone. E30+Meth = 522whp

You might have been thinking about the E50 Agressive Run 540whp, I'm not sure that was added to the JB4 programming, Terry may have thought it was too risky and dialed it down to be safer.

It looks to me like octane is near maxed with e85 alone... This would me much more valuable if shown w pump 93 and meth. Meth if anything in this scenario would offer additional cooling benefits but e85 already does a ton of that. Show a 93 + 100% meth data set please.

Intake temps and octane boost yes but the biggest plus of water/meth is big drops cylinder/exhaust temps that can fry a motor super quick.

[MasterC17]

I can attest to this - meth makes a noticeable difference. I need to get on the dyno, but my car should be putting down 550whp+ now.

We don't have pump 93.

[Bowser330]

Terry mixes in a can of NOS (w/MMT) to a full tank to make the 91 into 93.

Found a link that does mixing calcs for E85 if anyone's interested.

I've mixed 91+E85+Torco and it felt very strong, super easy and cheap way to get 100+ octane.

I'm interested in the following

91-93 pump
91-93 pump + Meth
100 Pump
100 pump + Meth
100% E85
100% E85 + Meth

+1 for 100% E85. Unfortunately, in my part of the country, we don't have anything above 91oct, or meth as far as I know. We do however have plenty of E85.

meth injecton is Definately the dumbest ass shit you could do to your new m3/m4, unless you want to greatly increase your risk of blowimg your motor. See the link for case in point

Do you know how many people use meth/water injection with zero issues? This guy is an anomaly...IF it was even the water that caused the issue.

That being said...I think people willing to run this (and the power levels that need it on pump gas) have probably already written off their warranty.

For track racing... yes I agree. Especially if you are running it for power and not for the cooling benefit.


The biggest overall benefit that I see here is for people who do not have access to E85 or race gas and wish to run more aggressive tunes w pump gas. Unfortunately this was never shown.

Well I'm sure most ppl still hope they could use the warranty although they should expect and be prepared to pay like you said.

Can someone explain to me how hydrolock can cause the engine to fail like this?

I ran meth on my N55 for 40000 miles without any issues... It can be as safe or dangerous as you want it to be. I personally had stainless steel lines running from the tank in my trunk and then underneath the car into the charge pipe. If you're gonna do meth.. Go stainless steel

which meth kit did you run, BMS?

will you add meth to your S55?

[kitesurfer]

Meth injection is not safe, hooking up rudimentry pumps with what amounts to nothimg more than agriculture spray nozzles is not safe. Can u say hydrolock. Running WW kits with high alcohol content is an absolute fire risk & yes guys cars have caught fire.
