I run water/meth as a safeguard/buffer. AEM, 125cc above 10psi and I think 3500rpm. Using turbo power washer fluid which is 50% methanol, pump mounted near the oem intercooler spray tank in the rear fender and using the oem tank for the fluid.

Personally I'd never trust a meth kit to operate as a secondary fuel system

im using mine as a safety measure also. im not looking to get crazy power with it but i want it to keep things safe since im upgrading to a socal v3 turbo. thats why i wanted the map switch. with aem off ill still have fun. but with meth on ill feel much better in higher revs

I used to feel the same way about it, only using as a backup.

But with the (new to me) option to map switch I can't see the risk anymore. Enlighten me.

If the meth flow is hooked up to IDC, and the failsafe is based on a lean AFR, how is it so different from filling up with e-85 one day and e-10 the next?

Not really different at all.

Only thing is, is coming up with the failsafe based on AFR. That I am not too sure on. A turbine flow meter would be easier to do I think.

If you come up with something that would failsafe on AFR please post it or PM me I would be very interested.

I was thinking flow meter too, but then nurp mentioned reliability issues with his AEM. That got me thinking that there is no failure to AFR beyond a failure that show itself everywhere vs. isolation to the meth system itself.

The AFR failsafe i use is this - Innovate PSB1 https://www.innovatemotorsports.com/products/psb1.php

Manual - https://www.innovatemotorsports.com/...SB1_Manual.pdf

It will need a relay arrangement just like yours as it's setup to cut the boost solenoid on overboost and/or lean AFR.

Interesting.

I thought about this.

I do have this sitting on my bench though.

Just compare the hardware, software and sensors you have to run your actual fuel system to the wmi hardware, software and sensors.

I would simply run e30-e40 at your power levels for a level of safety.

I came across that first one, and also considered it. The one on Amazon is good find if you could narrow the voltage down to 0-5v (sure there's a way with some know how).

There is also the Snow Perf. flow meter with a boost cut feature https://www.maperformance.com/produc...EaAiUYEALw_wcB

That was kind of my thought process for running an AFR based failsafe. The entire failsafe (ARF gauge) is taking it's reading off all those sensors you mention.

I have no ethanol beyond 10%. I've been using TORCO for ~ 100 octane but 1) it's a waste when cruising, and 2) it's a PITA to measure out 3 oz per gallon at the pump..., especially given we don't pump our own gas here in oregon.

I think I could.

Max flow (1gpm) would be no Jet and the line just free running. At rest it would be what ever it reads.

Measure the voltage with a DVM and see what it comes in at. Supply voltage would be from the other TGV.

I wish, the weather is so nice out but the dyno day is in May. Plus I have some boost leaks at the injector seals. Got new ones on route. Leaks at 30 psi

It's going to be a long month. Injector Dynamics o-rings?

How, or where, are you doing the boost leak test at? Do you rotate the engine so all the valves are closed?

Going to be a crazy long month, good thing I am busy until then mostly

Just on the coupler off the turbo. I didn't worry about rotating the motor off since my air compressor can keep up. I just spray soapy water at every connection on the car.

And yes ID o-rings. Getting new OEM ones.

do your ID have those little aluminum buckets that sit in the rails?

Mine are the ID 1300s and they have the buckets with super thin o-rings. those pop in the tgv housing and always pinch. I suggested ID include some spares given they are an odd size and likely a viton .... frustrating.

I need to boost test mine.

I think I had 3 issues with my AEM Flow Gauge.

1. always read 250cc/l more than the rated nozzle. Sent back to AEM and they said it was working fine so no idea what was going on.
2. had a slight leak from the sensor after about a year but I put some teflon tape around the threads and never had a leak after.
3. would not turn on when very cold. This was usually around -25 to -30 degrees celsius. If it doesn't get that cold where you are then you probably won't have the same issue.
