E85 Limited Late Switch

[Lizardracing]

I wouldn't argue that. He's got a lot..lot of self confidence. lol
He isn't self taught, he is a fluid dynamics engineer by trade. His practice is a little big to be a self taught hack.

He is quite straight to the point and sometimes crass. When he sends something out, and you have a problem or want to tweak a bit, it's not a big deal to him. However, lots of times a guy questions something and listens to all his gas carb buddies and ends up in the weeds and begins running his mouth about junk this or that. That sorta thing will get him fired up.
In that one case, he turned the screws around so you won't go messing with it. E sometimes like the floats a tad higher. All the internet BS says they SHOULD be in the middle. Middle is STARTING point, NOT the absolute and that for a gas carb. Not an E carb. They are all tested at his shop before it leaves on the brown truck using on the same E85 the customer is using, that all he does and has ever done. It was right where Mark wanted it, where it worked the best. Then Joe Blow read the internet and thought he was smarter, goes to messin with it and throws a fit because it won't work right.
There are probably better ways to handle such things.
Live by social media, die by social media I guess.

Mark has his ways, believes in them and they do work very well. Also sometimes a bit unorthodox.
Mark would rather get the call you aren't happy with something so HE CAN FIX it his way rather than some other carb guy telling his customers he's an idiot. You'll never hear about the good he does over the internet. You never hear about the vast amounts of free advice and knowledge and hours on the phone after work he gives out on the daily to guys who have NEVER spent a dime with him nor ever will. You never hear about the all the free work he gives out at the track helping people go faster, You never hear about the free parts he send out either when people need things. You never hear about all the good he does.
All this sounds like I'm defending him. I sorta am, I know him personally but have no alliance with him either.
He is good guy, just has a short tolerance for BS but at the same time, he ain't for everyone.
It doesn't matter if your a engine guy, transmission guy, chassis guy, construction guy, lawyer, doctor or anything else, the best thing to do is find the guy you can get along with and you can trust, and stick with em.

Eric is a super nice guy, sense of humor, really cares about what he's doing, is fair priced, honest, fast at what he does and all around very knowledgeable all thing ethanol with a background is CT stuff.

Either will help you win.

While all that may be true checking float levels is basic maintenence in a dirt racing carburetor. If your gonna run a special float level that hinder the float sight screws useless you should install bowls with sight glasses. Anyone that doesn't expect you to touch or check your float levels shouldn't be selling carbs to dirt guys. I'm not discrediting any of the guys accomplishments.

Yeah I'm with ya 100 percent. He doesn't do this with all of em, as far as I know a one time deal because one guy wouldn't listen. I haven't seen them all by any means. You can always call and ask questions, get the straight scoop on the deal, 6pm-9pm daily. He's a straight shooter kinda guy and not afraid of his own brand.

We've all been there and it's a tough situation to be in when you tell a customer something specific, like "level at the top of the sight glass" and every time is comes back because it's under performing, the levels are at the bottom because that's what the internet has said for about 60 years....and is wrong mind you.
At some point its better to tell a guy you can't help them, but they already spent their money paying the internet bill and the bash you know matter what. The internet is great for sharing information quickly, it's just as bad for sharing misinformation just as quickly. Neither EVER go away.

So are you guys running pump e85 or race e85 out of the drum? Im converting and I'm wondering if I have to buy it by the drum? Obviously I would test the pump stuff. What's the lowest ethenol % rating you can safely run?

[Higgy9991]

My plan is to run pump E85 and get a 5 gal pail of E98 and mix until it proofs at E85 so i can balance my own consistency.

[fastford]

some times you have to add strait gas to " proof" it down , I have bought e85 strait out of the pump that tested close to e87 , no big deal though .....

You have two choices. Pump or aftermarket by the barrel. Three actually, some areas have a VP gas station that sells per gallon. Look on their web site for locations. You can buy E98 and 87 and mix your own. I know guys doing that. I don't bother with the hassle.
VP E85 is complete crap according to my builder. It's always down on power. VP only makes it because the market is demanding it. Ignite brand and pump gas works the best on his dyno and his carbs. There isn't a lot of difference on the dyno between 70-90 percent so it's not an issue really. It's about the same difference between the early spring when its 40 degrees and mid summer when it's 110' in the shade. I don't know anyone changing carb jets for either of those scenarios and if you are, you're likely not on here asking questions. It's not enough that shows up on CT car anyway, Bracket racing where your chasing .001 ET's all day and night yes, slightly matters,it's even less on NOS or boosted applications. Mathematically it's 2-4 jet sizes. I don't worry about it and have no problems at 14:1cr 421. I said earlier look out for all the ethanol BS on the internet. Find a carb guy you like and stick with him. Do it his way. Lots of ways to make it work.

This is some awesome info to consider. How about any additives? I see a few companies making additives that have anti corrosion and lubricant and prevents water accumulation... Anyone have any experience with this stuff? Could it hurt power?

[Lizardracing]

My builder doesn't care for them.
Some of his customers say they like it.
Jury is out it seems.
I personally don't, never had a need for it.
E isn't corrosive, it's actually a cleaner. When it gets water in it, or when the gas part of it deteriorates is when you get problems. If you have problems, fix the storage issue and those problems go away.
I keep mine is sealed containers for up to a year, no problems. I keep the fuel cell and carb full if not racing for a month or more. Otherwise I don't do anything. Pull it into the shop, turn it off. walk away.
There is one thing, if you fire the car to show off or move it around or something like that it's best to get up to temp.
What happens, is the sudden change on the E/G blend sand it might turn into a real thin this jell like texture. I don't understand it personally, how it happens exactly, I just follow advice to always get it to temp.

Thanks for all this awesome info!
