Gas vs Methanol

Drag Test between methanol and gas.

[@rjreynold2372]

Hey Eric let me start off by saying that in all of KZbin, your videos offer the absolute highest amount of relevant technical content per unit of time watched. Hands down...no contest . Heck , I paid Darin about $600 for a lot of what you offer for free. I mean that was a while ago and I still consider it the best 600 I ever spent but I still appreciate what you are doing. Second, get you some EFI. I convert Harleys into "manual flex fuel vehicles" and alcohol is liquid torque. Most of my builds like to hit lambda .82-.825 by 150-200 rpm before the torque peak and then taper out to .85ish by the horsepower peak. I'm a big time data shithead and being able to tune each cylinder as it's own separate engine is like a gift from heaven. On a Harley with alcohol a 3000rpm spread from peak torque (low 4k's rpm) to peak hp (low 7k's) is a reality . Give it a try sometime

[@WeingartnerRacing]

It hard to invest 10k for a good EFI setup when for that money I can get a liberty trans.

[@johnginnitti4598]

Eric, excellent content as always. You can hear the car beginning to recover from the tight converter out about 150 ft. a 6100-6200 rpm stall would let that thing leave like it had been hit from behind by another car...LOL....but you're going to a supercharged 406 next year so what's the point other than burning up more time and money......honestly, for as much as the engine is handicapped by the tight converter and the weight of the vehicle and awful weather the thing really flies....its a great showcase for your porting/ cam design and engine building skills.....please keep the videos coming....thanks!!!!

Man, I'm impressed! 3200 lbs truck with an engine that generally has difficuly making over 400 hp with decent parts! Yeah, I know that these are really good parts but almost an additional 300 hp! I believe you've found a new client. Exellent videos and like to see your runs and time slips.

[@Fk8td]

Methanol also makes more torque because the oxygen content by weight is 50 percent. Low rpm doesn’t have as much cylinder temp so it’s not all about heat absorption. The cooling effect is more horsepower on a forced induction application from the cooling effect itself and this is why it’s a larger difference compared to an NA engine.

[@melissamcallister2867]

Methanol and Nitromethane are both oxydizers creating there own oxygen thats why people can run these fuels so rich .Nice video 😁

[@G5Hohn]

Methanol isn’t self oxidizing as I understand it, but I guess it depends on how you define that. But it does have a much lower stoichiometric AFR, about half that of gasoline. But still a lot higher than nitro.

Love seeing gains on the s10! At this point, I think 100 shot would give you the tq you need to get out of the hole, and I bet won’t have that draw down on the converter but you may have to go back to the 4.30 to have the gear to run it out, what do you think? With the fuel out of the gas tank, and good air I think it will be knocking on 10.50s

[@hughobrien4139]

Nice work! You shared a ton of information that people can learn from. I hope to see some testing done while you’re headed toward the rich side. I’ve been around these circumstances several times and it’s always fun to see seemingly small changes deliver such large results. I do not think you’re crowding anything for area on the intake side. Just a maybe on the exhaust side for methanol. I’d like to see some easy changes made on that side. Maybe a tighter lash, rocker ratio change. I could be out in left field with that idea.

[@WeingartnerRacing]

I doubt I mess with lash but I may mess with shocks and jetting next.

[@nhragold1922]

Only problem I have with gas is weather changes, humidity, and after 4th round, or double entry's. Hard to keep it cool. The q16 is good to eliminate weather fluctuations, but it's unreasonably expensive. Slightly more stable a little fat running c14 vp. I am finally making the switch to alcohol this winter though.

[@oikkuoek]

That rear end acts surprisingly good. Not perfect by a long shot, but could be a lot worse. I would try to get the power valve to work, and tune the jets for part throttle starting at 50% and pushing it to 100% before hitting second gear. This should take care of the richment on low revs, and lean it out at top end. For the exhaust, everything could be a size bigger. The heat colouring comes from restriction. 1/4 inch bigger primaries, 1" bigger collectors, x-pipe and Nascar style wide ends. Transition from head to tube needs to be smooth and about 4" long, and the ends about foot wide pointing upwads and aft. This helps with scavenging on high speeds, and pushes the rear down on low speeds.

[@pedricktownperformance6781]

Nice truck. Curios what the converter slip % is on the top end. Rpm seems high for the mph.

I am going thru our 355s lack of torque too , same bte tranny as you & sent bte 8 in converter to loosen up 400 more on launch & am crippled by air flow & can’t get it to launch over 4800 on brake , this fall I plan on calling you as a customer & upgrading to a solid roller & “USA” made allum heads that’ll let us have true volumetric efficiency.

About 4 years back we dyno. tested the the length of pipe after the collector. 18.inch was optimal. We couldn't.decide if it was the pulse or laminator that was in play.

Try this mate. Put some paint on your collector extensions, after a run cut the extension at the point the paint stops burning. It’s an old trick I learned years ago.

[@JohnThomas-vb9se]

I know this is a comparison video on fuels, and I’m no expert, but it seems like it may help a little if you can slow down the rebound on the front just a tad, and add some compression if you have that capability. It’s hard to tell, but it seems like it bounces and I’m sure it’s not helping your 60ft. Love the video, been thinking about trying methanol myself.

[@WeingartnerRacing]

I will try that next time.

[@mikeshelton7750]

Hey great video. Didn't see on any other video if you have ever tried short shifting it to get better ET. With that extra torque may see some changes. I know it's a comparison video but I was just curious. The converter does seem a little mismatched for this combo.

[@WeingartnerRacing]

I shifted higher in this video and it went faster so I don’t think short shifting is going to make it faster.

[@cmdrclassified]

Good stuff, Eric! Very interesting. You mentioned the possible loss of power due to the methanol evaporation caused by heat. I was wondering if using something like the Snow Performance boost cooler would help with that. I know it is a mix of water and methanol, and I have seen good results with gas engines, both NA and boosted. Thanks for sharing your knowledge with us! o7 PS: You really have to speak to your cameraman(woman) about filming the burnouts! LOL! At least we got to see one of them though!

[@WeingartnerRacing]

That was my son filming and yea he missed that.

[@Dr_Xyzt]

Methanol boils at 140F. -- I don't think methanol evaporation is really what gets us. When the fuel hits a surface above its boiling point, the fuel converts from liquid phase to gas phase and occupies more space that would otherwise be occupied by useful air. -- I have a theory on how to test this. A small block chevy with standard valve angles will lose more power at the top end where the horsepower is already beginning to decline. This implies that the fuel is hitting the head and cylinders due to all of their crooked geometry. The mid-range power is probably killer though, because the fuel is kept suspended in the air and has time to exchange heat.

[@nathaninwa240z]

Awsome content and enjoy the comparisons you do. I to am a methanol guy now coming from ethanol! Do you ever look at the plugs for fueling and timing? What did you find as a timing difference on the dyno from gas to methanol? Appreciate the content

[@blueyhis.zarsoff1147]

my question too, my guess is it would need a unique timing curve?

[@WeingartnerRacing]

I left the timing the same for both fuels. Judging by the plugs it looks perfect.

[@johnfry9010]

It takes a lot to run 10's , sounds good !

[@nova467spanker]

Eric, watching your 10.76 run reveals you defiantly need to do some shock adjustments. Your truck is hitting the tire hard and bouncing. My car does this and will knock the tires loose. That is with the old Lakewood 90/10 and 50/50 shocks. I put Rancho 90/10 and Calvert 5 way rear adjustables on it now but I have not ran it yet.

[@WeingartnerRacing]

Im going to play with the shocks next.

[@mohanperformance.enginerd.1308]

Well. I am reluctant to offer ideas to try. Because 35 years racing later. I have learned I dont know very much. But if I were to guess. I would try opening your exh lash .010" and make another hit! If that works out. Then remove two deg of lead "timing" and try another hit. If that works out. Go get a lock up convertor for your glide and add more rear gear. But these are just my own guesses and you need to take them for what they are. Oh, one more thing. I am definately no superman. Cheers! Tom

[@WeingartnerRacing]

I may try a lock up converter on the new motor.

[@gregredd5374]

[@Speedy123youknowme]

Man I live in Owasso just north of tulsa raceway park I grew up at this track!

[@countryboysteve]

In the mechanical injection side we always said make it so fat that it flutters then steal 2 jets. That's always been a great start point. With all the added o2 in the fuel you can add fuel to the point it will wash the rings and still run a dang good pass. Instead of running a 12ish afr we ran something like 5.5-6.2

[@WeingartnerRacing]

I’m on the gas scale on the o2 not methanol scale.

[@countryboysteve]

Fun thing with methanol is that when you get it to fat it just doesn't run kinda like a 30 year old junk carb with a bad accelerator pump. We just keep adding pills till it stumbles back it down a couple and go. It is so forgiving. I love it.

[@treyrags]

Just a suggestion on your suspension. Looks like you have a little bit of leap frog going on. I think there is probably 3 or 4 hundredths on your 60' if you tighten you tighten your rebound to slow down the front end rise on launch. Could gain .08 or so on the run. Worth a try.

[@WeingartnerRacing]

I am going try to do that because it does leap off the line.

Best time it ran with that setup was 11.25 @ 122.04... I installed a Accel gen 7 dfi in 2009 and couldnt tune it at all and now its sat for the last 13 years... its only got 800 miles on everything since 2005. one trip to the track rolling into the throttle (traction limited) net passes of 11.25, 11.27, 11.31, 11.37 (not in that order)...

Hi Eric. What can you get a ls3 Dart PRO1 head to flow @ 700 lift? Have you ever done them? What dose the truck weigh? Wouldn't the truck run a bit faster with higher water temps letting the oil heat up and boil out any water that get in the oil? Turbo W/O intercooler would make it fly on methanol !

I think it would be really interesting to see what this engine does on e85. I bet it would make just about the same power and torque. Where I live e85 is close to $3/gallon. E85 wouldn't be my first choice for the 15/1 engine in your Camaro but it wouldn't be terrible and would be very interesting to see.

[@WeingartnerRacing]

I just don't see the desire for E85. I know it will not be as fast. The pump E85 isn't consistent and the race E85 cost almost as much as methanol.

[@Dane33781]

@@WeingartnerRacing E85 test kits are cheap. The blend consistency is a problem but less so for the fuel injection crowd who has ethanol content sensors and offset tables to compensate. Even if you're not a fan of e85, you'll probably get views. You should set up a poll to see if your viewers want to see videos about it. I do.

[@Kashed]

Eric, did you upgrade your fuel pump? Do you have a g meter in your system? A loose rule of thumb is 8 psi of fuel pressure is lost for every 1 g of acceleration. So for example if you are pulling 2 g’s of acceleration and have 16 psi of fuel pressure, the fuel will literally stop in the line for a moment and I have seen many layover issues caused by this issue and people always think their pump is strong enough and never is.

[@Kashed]

Just an FYI also, many running methanol have the tank in the front that helps prevent this issue. You could try running a small temp tank for single runs to test it. Of course just make sure you have all the needed safety fire equipment. That stuff burns invisible!

[@WeingartnerRacing]

I have a pressure sensor with at the regulator so I data log pressure. It stayed at 5.2 which is fine.

[@terrysmith8133]

fyi, the front of the truck looks in the video to come up and then down then up then down. usually you want the front to raise once and then slowly come down. not motor related but sometimes e.t. related.

[@Anarchy-Is-Liberty]

The temp dropped like 3 degrees from the first meth run to the second with the collectors added, so I'm sure that helped a little as well. Also, what about E85? Would E85 make as much horsepower/torque as Methanol?

That under hood temperature is killing your engine power. I tried a K&N velocity stack on a flat hood and it improved.2 tenths in the 1/4. Methanol burns slower and is self originated so the richer it is (within reason) the more torque it will make. It’s not rich enough if it’s not burning your eyes and nose lol. You can purchase scented oil additives for methanol to help with the stinging plus it helps keep the aluminum fuel fittings from getting eaten away by the methanol. (Been there done that). Best of luck

[@WeingartnerRacing]

I took off the air cleaner before and it slowed down. I use a top lube with methanol that is grape scented.

[@ericschumacher5189]

Hey Eric; great video (I hope my comment is helpful to you) keep up the good work 👍 1.) Are you adding an upper cylinder lube? (if you aren't I'd suggest it for the corrosion protection alone, but it can actually help performance slightly, and Klotz is about the best). 2.) If you switch from track-methanol/M1 to VP-M5 you could gain up to 2-tenths (it will cost more, you will use more [+10-15% fuel demand increase], and your current practice of draining the system post race is 100%-NESSARY) but its big gain for not much change to your setup. 3.) The carb spacer on methanol can make a pretty big difference due to the sheer volume & size of the droplets entering the engine (sometimes the anti reversion type spacers pick up on a methanol due to the shearing effect alone, not from what the spacer is advertised to do). 4.) There are certain spark plugs / heat ranges better suited than others for M1 and M5 that can show some gains, as can tuning the gaps, due to plug wetting and ignition strength. 5.) You may be surprised, but MORE engine temp may run faster; on mechanically injected sprint cars, its pretty well known power can increase by 10-15% when the dyno water is increased from 140F to 200-210F (your mileage may vary depending on the tune up). 6.) Not sure how much you played with timing on the dyno on methanol but it can be a bit fickle when the AFR's are on the rich side (not due to detonation but due to plug wetting), so there may be some more left, especially if you change to M5 / change plugs / change coolant temp. 7.) if you decide to cut the extensions down, I'd recommend slash cutting them at a 30-45 degree angle with the short side of the cut being at your expected ideal length, this lessens vena-contracta and conditions the return wave like a reverse cone on a megaphone extension would; it probably wont be worth anything , but it has the best chance of a tangible benefit.

You're lean on every pull! I don't understand why you're trying to keep it stoich at the torque curve. In my experience Methanol afr needs to be at 5.4 to 5.7 for NA power tuning and 6.1 to 6.4 at idle. Boosted applications need to be 4.8 to 5.2 but maybe it's different with your altitude where you're at. I'd have to take some gear out of that thing! I don't like being on the chip while crossing the line like a lot of people suggest. That generally means you have overshot it. Most people shift a little after peak HP, so that tells me I'd be better off crossing the stripe a little before the rpm that I make shifts at.

[@rtkl13]

Dig it I'm in your corner on this one, I'd be fattening up till I know I'm going wrong. It wasn't rich on fuel and then gained torque by switching to alcohol. The truck sounds over geared or something as he stated there is some stall issue or delay going on at launch

It was on the limit because I over ran the stripe.

5.7:1 isn't exactly rich. The lambda for that number is 0.9 which is like 12.5:1 on gas. -- Yeah, 12.5:1 on gas is kinda fat, but it's not THAT fat. I mean, 9.0 on gas is FAT, which is a 0.73 lambda and your 4.8:1 methanol value. -- For naturally aspirated power, I think it's perfectly fine to tune methanol to relatively stoichiometric levels. It has 6 times more cooling power than gas, and knocks at a higher temperature, so a good running gas engine will LOVE methanol. -- Methanol is a very simple molecule, so it combusts more predictably, even if the mixture is off by a little bit.

If you go with less compression, like 13:1, since the fuel boils below the engine temperature, the fuel will passively cool the engine and make the compression cycle easier! End result is a more durable engine!

[@updragracer]

Definitely sounds better in 1st gear on methanol

[@mikediamond1522]

More compression. Running rich. More timing? Spark plugs? Methanol lube! Mike

[@needmoreboost6369]

Add sea level air and hold on!

[@TRSCobra]

I may have missed it but which methanol were you running?

[@WeingartnerRacing]

Regular Sunoco

[@TRSCobra]

@@WeingartnerRacing any intentions to try VP M5?

[@jasonhaley5737]

The converter sounds extremely soft/lazy in that thing. Call FTI and order part number SS888BA. My truck will 60' 1.39-1.40 with that converter, and I have about 150 less horsepower than what you have.

[@WeingartnerRacing]

What does it weigh.

[@jasonhaley5737]

2970 with me in it.

[@garywhiplash8952]

Fuel injection works better and less maintenance. Also check exhaust temperature should be around 1200

[@WeingartnerRacing]

Yes at 10k for a good setup. 10k could get me a liberty transmission.

@@garywhiplash8952 I cant see spending 2k on the Ron’s when this works good. I don’t think it would be faster either.

[@jodysmith3662]

I think leave rpm is hurting it some. Lower I have had better results. 4000 or so that with a 6000 converter.

[@WeingartnerRacing]

It went faster when I left higher.

[@youngracingengines]

Have you tried E85?

[@WeingartnerRacing]

No

[@ThePeopleVerse]

Why you are not in the 1.30's for 60' times is beyond me. Are you running leafs or 4 link.? Not, from what I can see, getting separation after launch. You sure have it hooking though. Not a single break.... pretty sweet.

[@Mickss355]

Also let peeps know. That methanol will put moisture thru your engine. Also contaminate your oil

True Duel exaughst is over rated throttle resonse is ok but your engine fires 1 side at a time start stop start stop . kind of like car pile up a 3 inch from each header into y and 5 and a half in bottom Single will make way better velocity and actually draw air harder in cold air intake my boss had 4 nascars 2 with y pipes 2 with duels ys won we even put a bend in pipe and it directly charged charged the carb better it made more power than open carb just some thoughts

I would think for a engine that’s only 355 cid and running 124 mph that carburetor on methanol are gas is way to big it would more than likely run quicker and faster with only a 750 methanol carburetor.

[@WeingartnerRacing]

I tried a smaller carb it went slower.

Really I race a 1972 stock eliminator mustang with 351 cleveland and it has 780 vs and car weighs 3500 # and in bad air 3500 ft plus runs 10:70 at 124 are so and in Las Vegas it runs10:80 about 120.

[@alvinwilliamson2461]

All I was saying is that maybe the carburetor is to large and I just have you an example of car/engine with a smaller carburetor that runs quicker.And that it was not to criticize what you are doing.

[@WeingartnerRacing]

@@alvinwilliamson2461 I’m not upset and I understand where you are coming from. I believed that too because the internet said that same thing. So I went from a 830cfm to the current 1000cfm and it gained .12. On the dyno on almost every motor with the exception of one going bigger made more power and torque everywhere.
