Why You Should Run Methanol on Your Racecar - Pros and Cons - Twin Turbo Ameri-Barra 4200 Datsun 

You didn’t mention the safety aspect of methanol, invisible fire is bad, most people have never seen it ( no pun intended ) and you should be running a comprehensive fire suppression system as well as better fire suits, Tom Bailey has a great video on this I highly recommend watching for anyone considering running methanol fuel. Be safe to race another day.

Since you are running a coolant system, you can lean out the idle. A lot of the “milking” is from guys running it really rich all the time because they don’t have a cooling system. Also if you just let the motor heat up the oil each time you start it, you’ll also be fine.

Great video. I’ve yet to run pure meth but I’ve ran a dual fuel setup which made 50% of my fuel load at full boost be meth and it worked amazingly well

You weren't kidding Calvin... Was the best meeting you and your mom and dad.Your car was the best build there Calvin!!! NIVLAC57 RULES!!!🔧🤘

The 4200 and that Datsun are a perfect combo!

You guys are really stepping up to the plate!

I'm excited about this one too! 👍

That's why I inject methanol into the intake manifold with it's own pump and tank and injector. I still use an intercooler and no concern with my gasoline fuel system which uses 100octane. I do however do 1k oil changes as this is a street car not a race car.

Dude I love you man

That is bad ass!

evaporative cooling is the process you are describing at 2:00. the boiling point of the liquid is what determines the evaporative cooling. methanol is one of the most volatile alcohols and it just so happens to have a carbon oxygen bond and a lone pair of electrons surrounding it. methanol has a very low calorie count so the stoichiometry is roughly just under half of what gasoline is. ethanol is slightly higher boiling point, and is roughly 3/4 the stoichiometry as gasoline. it takes 3 molecules of oxygen to combust 1 molecule of ethanol. it takes 1.5 molecules of oxygen to combust 1 molecule of methanol. methanol is a very good polar protic solvent, so it requires special lines, tank, pumps and injectors. by knowing the chemistry and how to balance a combustion equation we can calculate how much ethanol/methanol is needed to be used. You should also ring your pistons specifically for methanol as you will likely wash a cylinder clean of oil with the volume of fuel being used. you should also bump the compression up significantly as methanol/ethanol are knock resistant. part of why methanol engines make more power is because you can safely rev them higher with more aggressive ignition timing. the higher boost plus that ignition timing = power. the rpm is where you see the best gains on methanol at least in my experience. ps. methanol burns invisible and you had better have a VERY GOOD fire supression system built into the car. i can show you what happens when you run methanol with open downpipe that dumps under the car... i know of several cars where the entire car burned to the ground.

Use vacuum after a run helps cool engine also evac moisture

Calvin, im sure its crossed your mind but why not run on E85 until the trans brake is activated and have a tune that switches to Methanol for the pass then revert back to E85 when driving back to the pits?

SRC runs meth on the S10. They use a lean-out valve during the warm-up to help prevent milking the oil.

👍

Nivlac57 I wanted to ask do you do the 4200 for customers . I was going to go 2JZ but after seeing your videos I think I want to go with the 4200 . Please let me know

Methanol; liquid intercooler. Lol. Really makes a difference on roots blowers. Takes the heat right out of it. About the only way to make one half way efficient lol.

Will the switch to methanol mean nitro at some point?😁 Could be fun💥

Just testing straight methanol with no intercooler on a 4 cylinder at the moment, like you say it means I'm lighter and I've had it up to 40psi up to yet, though I was expecting a reasonable drop in temp with a single 210lb spraying into the chargepipe but was still seeing 150c by the end of the run so didn't seem to make a massive difference

Have you researched what oil to use? I have seen 1 brand of oil allow the methanol separate and settle on the bottom of the oil pan.

I wanted to know why top lube was prohibited so I looked into it and apparently it's because they can't tell the different between top lube and performance enhancing additives during fuel checks on classes with fuel restrictions.

What kind of oil yal going go run?

if Methanol is corrosive to aluminum isnt it going to eat up the heads of the 4200?

Would running gapless rings help keep the methanol out of the oil?

In short....more power, more maintenance, less weight and smaller bank account to build a methanol system thats reliable.....yep i have to have it, why stop with all the normal challenges of drag racing lol

A lot t consider!

Why the SnakeEater injectors? Are they sponsoring them to you? I would at least get a set from a reputable vendor like Viren.
