I am getting ready to have my procharger and headers installed on my 16 2ss. Its a d1x with helical gears, red race valve, and a stage 2 intercooler, kooks 1-7/8 headers with offroad pipes. Im kind of curious how methanol works. Plan to go with a stage 3 snow direct injection/forced induction kit, but honestly probably wont have the funds to buy and have that installed for a couple months. If I have the car tuned to 4-5% of the cars fuel availability for max power, when I do buy the methanol kit will I just install it and start injecting without retuning and everything will auto adjust? Ive seen multiple people saying you can install it and a tune isnt necessary, but I want to verify before I choose to wait to buy, or wait on complete install for charger and meth kit and donit all at once. I want the meth for the extra power etc, but dont want to completly rely on it and risk engine damage. Any help or advice is appreciated!! Thanks

With the Meth kits I have installed and run lately they need a tune for sure. Most spray way too much meth on the factory settings. Say you get the fuel dialed in to 12.0 at WOT on pump. Hit the meth and you are in the 10's on AFR. From my findings, these DI motors don't like anything fatter than 11.5. I have seen fuel knock and other issues when these cars get rich. I do everything I can to minimize this effect and only pray enough to get the AFR to 11.7 or so. But then it seems that I am not spraying enough or using enough pump pressure to atomize the meth properly. From talking to guys that do this all the time, it seems that to get it right you need to run the proper amount of meth and then lean out the pump fuel to get your AFR correct. For me, on a street car, this is pure danger. Something goes wrong with your meth kit and there goes your motor.

But I will defer to the experts on this one. There are some spectacular tuners on here that use meth all the time. When I do my blower set up I will be running it for sure. I personally wouldn't run a blower car without it. You just need to know what you are messing with and how it works.

I always recommend going to the source with specific product tuning.

[Daniel20162ss]

The car will by no means be driven on the street daily, but will be a weekend toy, maybe go to test and tune now and then. I know im looking at 580-600 or so maxing out my fuel system without meth, seems meth may get me to 650+ but I dont want to do it if its high risk. Afterall, reason im wanting to go meth is because I dont have the cash to buy all the fuel system upgrades, I damn sure dont have the money for a engine that grenaded. Lol

[Daniel20162ss]

And the tuner im using has done an abundance of procharged cars, but not much with the direct injection on c7 and gen 6 camaro. Hes actually talked me out of the cam replacement, and right into the procharger for now and maybe cam later. Ive been doing alot of reading and alot of the well known shops are using methanol to get their 650+ numbers safely, so I then threw meth in the mix.

Pray's point about using meth injection as a supplement on a DD is a good one. I had meth injection on my Audi TT and lost two pumps before I gave up on it. I was fortunate enough to catch both failures during normal cruising, so no engine damage.

If it were me, I would consider just a water/meth injection mix to control IATs verses octane boosting. No fire hazard and not a catastrophic as losing a pump at WOT with pure meth.

[Daniel20162ss]

My plan would never meter on 100% meth, leaning more toward a 50-50 mixture or even doing the -20 windshield washer route. I would never run over 50% meth

[PRAY]

I have never personally used meth for a fuel source. I only use it to balance IAT temps from winter to summer so I don't lose 100rw. Actually, I lost 120rw. I know with how knee capped GM left us base line Camaro guys that you have to run meth as a fuel at some point depending on the power you want. I hadn't thought about cutting the meth with water to keep the octane/AFR changes to a minimum. I will have to test that at some point.

I am always an advocate of building the most powerful motor you can afford or tolerate prior to going to boost. But that is just me. For the DI stuff it does make more sense for a DD though. Even a solid weekend car. Less boost equals less heat and allows for more consistent power levels year round. So, to me, camming a boosted car with a 32% fuel lobe is a no brainer. There is no down side really. More power, less boost, and more available fuel potential without breaking the bank. I am pretty sure that with a fuel lobe and a ZL1 in tank pump you will be able to take the stock short block to it's limits on pump gas. Then add meth or split your meth and you shouldn't have to use it as a fuel source but as a safety feature and a mechanism to control hp loss due to heat.

Both Pray and Procharger, what pully would you guys recommend on this setup? Ive actually decided to go with the d1sc charger with stage 2 cooler tuner kit, and I am doing a meth kit that I plan to run the -20 washer fluid in. Im about 95% sure carlyle racing will be doing my tuning, they are local to me. Just wanting to make sure I take advantage of all the power I can, and will wind up running the correct boost level with runing meth. Again, cars stock other than prays ported tb/intake and the headers that will be installed

I have no idea brother. Procharger will be the man with that question. He has done the most testing on the stock short. In my mind it goes, power desired = boost level = pulley size. I do think you will be down a pound or so of boost with the ported IM/TB and headers over stock for the pulley size you run.

I run it with my magnuson setup. I works very well for sure. My car runs pretty stellar even in the hot temps and that's mainly where I'll use it. I run a 65%water and 35%meth. Its a good combination. I run Vp MS109 at the track and 93 on the street. I've had no issues to this point and don't expect to.

[Dysan911]

I would definitely like to know more about how to use meth to control IAT's. WHen I first started reading this I thought. Cool I may learn how I could benefit using meth but then the discussion started to worry me about pump failures, tuning, etc.

It is so hot right now. Is the -20 washer fluid what you guys are referring to for use in just cooling down the IATs? and does any form of using meth require tuning?



THanks!
