Engine blew up

[metalhead79]

I guess a better way to say it, is I'd only consider WMI for safety, not as an octane booster to tune to. I'd use it to help reduce temps, especially if pushing s turbo or SC past it's normal operation RPMs where it's generating more heat and you want to bring temps down. But I would only tune to the base fuel, then turn on the WMI for safety. It's just too risky.

This is where larger displacement NA engines shine, I think. Especially V8s. You can get lots of power out them safely on pump gas with no worries.

Even with E85, you're still trusting your engine to an external controller. I think WMI would be a great way for you to achieve your extra power goals while not having the extra responsibilities of E85. As long as your controller is installed properly with the correct safeguards, it'll be just fine. I always checked mine (on previous cars) when I would fill up with gas. It only took a couple extra minutes, if that, and I never worried about the tank going dry. WMI is a really good alternative to E85 that requires less maintenance, per se, and still offers a majority of the benefits. Plus, in most cases, it's cheaper to buy and install the kit.

This is why I appreciate your info Juben.

I agree 100% Running Meth is cheaper than e85, it's more consistent, it not only raises octane but has tremendous cooling for your combustion which makes running power incredibly safe. Most kits have many safeties that will simply switch Maps to your regular octane tune or tune the engine down so you don't do anything wrong. And especially for me without having too many resources of E85, meth is convenient. Look up Valves after running 50/50 mix injection, great bonus for us DI engines.

These shine on Forced I diction motors where temps rise a lot. If you have an intercooler and Meth, you can run some more PSI and still operate incredibly safe. V8 or I4

So is it perfectly ok to use a WMI with just the standard average 93 tune just for safety and if the unit were to fail or run out nothing would hurt until I get it filled back up again? Other then the added extra safety of course. It would probably do a better job of keeping the valves cleaned compared to a Catch can too.

I meant that with a V8, you slap some headers on, maybe get a tune and you're off. No worries.

On our turbo'd I4's we have to upgrade the intercooler, then tune, then worry the tune will make our engine toss a rod, so we add meth or E85, etc... NA V8's just seem simpler to mod. Or maybe I'm just over thinking it.

There's been several new Coyote motors to blow up as well. Risky tuning is risky tuning, doesn't matter if the motor is a v12 or the new 3 cylinder ecoboost.

Also, a full bolt on car is NOTHING without a tune.

I would definitely get a catch can before the kit, I'm doing that part backwards. But yes there are safeties wired in to ensure you cannot run the car when you have no Methanol flow. If your curious there's a good video from AEM (the kit I ordered) where they explain that and they tried different scenarios to run out of fluid but the safeties always stopped like they should. It's easier to keep a check on Meth levels than constantly sample your E85 station, do tank fill calculations and plan your trips around E85 stations. With the meth, you do a tune, make sure everything flows good and fill it up. After that just keep an eye on your levels. No mixing,calculating, and cheaper. Then you get more boost, safer temps and cleaner valves. Wins for everyone :cheers:

Can you mitigate the carbon buildup with a catch can and meth?

That's one of the best benefits. Early on some guys started with meth and someone showed their valves after some time, they looked perfect! I'm not sure if the pics are still available.

Man, that is really tempting.

There doesn't seem to be a downside to WMI. Other than that whole warranty voiding thing. But then, if you're doing these kinds of mods you should be smart and not doing it if you can't afford to fix any 'oopsies'.
I want to tune, since that's the money maker on these EB engines, but I want to mitigate the risk of tossing a rod as much as possible.
I'm not doing anything until after our new home is finished being built and we've moved in and gotten settled. My wife will kill me if we have to replace an engine out of our house money savings.

A good tuner will pull as much boost from the new threshold WMI offers while using the new lower temps to keep things safe. Good performance gain, GREAT cooling under load. Pair that with a good IC and I dare you to get dangerous temps lol if your gonna tune, your voiding the warranty anyways, WM will help ensure you don't see the dealer again. It's not fool proof, nothing is. But great prevention. I'll post HP numbers after I get mine in and tuned

Keep us (me) posted!

Like I said, I won't be doing anything until this fall. I'm about to install my catch can this weekend, then order a UPR crankcase breather valve and I'll be done modding until the tune (ok, that's not entirely true. I'll probably do cosmetic things. I also have a shift knob on order from Anarchy Motive).

I understand nothing is fool proof. I learned that the hardway on my 97 GT when the backyard mechanic I knew botched the ported head/cam install on my 4.6L SOHC. $5k later I had a brand new 03 Mach 1 crate motor.....

I was using a Split Second piggy-back to tune for A/F the last time I used WMI and it was too many years ago to remember but don't you have to tune for the WMI? I mean you couldn't just install WMI on a stock tuned car and run it that way for the benefits of lower temps, clean valves and higher octane right? If I remember correctly, you are injecting more fuel in addition to what the ECU is delivering so you have to tune accordingly? Also, I thought I remembered something about the methanol doing something different with the WBO2. Maybe it was as simple as changing the stoich target?

I'm a little limited on my overall knowledge of it but from what I've gathered, yes you need a tune. Always tune for any change besides a CAI or plugs lol

Your octane will be enhanced but the major benefit here is the cooling provided. This is where the tune really comes in as your benefit will be greater boost and a balance between the temps from boost and the cooling from the injection.

If using a 50/50 mix the octane increase is similar to E30, correct?
