It wasn't bad. There is just a spot it needs more fuel down low. It wouldn't change street driving though.

@@WeingartnerRacing This is a very good video with some very good base of information which most are unaware of about fuels and these measurements. Eric am glad You used a 'race' E-85 which is commonly called C-85,[correct ?] which is 85 % ethanol - not like the E-85 at the fuel stations which can be 40% ethanol often in the winter months up to 55-65% ethanol. Do You have access to 100%Ethanol or the racing ethanol which is used in IndyNTT - they had switch to ethanol from methanol since 2007. NASCAR use the racing E-85 or C-85 for their events. It would be interesting for You to perform the same measurements with using racing E-100 . the measurement may be much closer to methanol also. Also, as most re not aware, that both methanol and ethanol have far less carbon in the molecules, and fuel thus far less carbon in the burning resulting in far less carbon deposits, build up on the spark plugs, inside the cylinders, heads, combustion chambers, on the valves, exhaust ports and pipes. =>Thus, the benefits are beyond just the simple measured power improvements too. The combustion result in maintaining cleaner engines components and more consistent performance during longer operation and longer use. -> common 'gasoline' has many higher order hydrocarbon molecules which have much higher carbon content, but nigh higher level power from combustion. -> also similarly another common misconception is using race fuels with high octane via tetra ethyl lead, as with C100-16. the higher amount of carbon is worse with the tetra-ethyl lead. The purpose of higher octane is to slow the burning, as require with higher compression, It does not provide more power nor good for lower compression nor with induction, air compression using turbochargers or superchargers. -> as we know the addition of NO2, nitrous-oxide into the fuel increases the resultant power from combustion, and burns very rapidly, thus must be controlled properly since can burn so rapidly it nearly explodes. -> would be interested to see if You or someone can perform Hydrogen injection and measure the power increases from combustion -? since Hydrogen combustion [H2 + O2 + heat] is the most essential power with the hydrocarbon molecules. All The Best Sincerely

@@newtonfirefly3584wow, I just learned some things reading your post. I think you just touched on things that every hot rodder should know or at least try to understand. I’m thinking that 90% of the engine people I know really don’t understand octane/compression relations and how to utilize them together to get a viable outcome. If you know where I can get more information/videos that go into this more in-depth, I would appreciate it very much. Thanks again! Tony

@@grendel.6.531 Your comment is a rare, positive awareness; also much appreciated. Am not able to properly asses, evaluate the actual portion of individuals which lack these basics. However, from the many videos, channels which are certainly limited, a large portion of them are clearly lacking, unaware, confused along with basic distorted ideas, concepts, information about fuel, compression, ignition, along with lubrication, proper-optimum operating temperature, air flow for the engine along with aerodynamics, traction, mechanical structures, forces, electrical, electronics, full use of a computer including ECU-ECM-PCM, TCM. The few which has some various correct basics are immediately apparent, obvious as those which lack. Thus, all proper, professional racing teams have necessary experts including engineers for proper design, development, racing, results, All The Best, Sincerely

Now we need to repeat those Dyno test with turbos. I just returned from SEMA was there with Comp turbos.

This engines is going to be on turbos next.

It’s made for blow thru so I didn’t expect it to be perfect. It still did good

Thanks

What cubes & compression do you have?

It’s in the video graphs and all. Watch it all the way.

No there is a certain amount of air circulation that you have. He has plenty. The doors are just not perfectly sealed.

My favorite is methanol it makes so much torque

I agree. The maintenance sucks

What are 3 problems you've had with methanol, and how long did it take for them to happen? -- I'm focusing on stopping corrosion. -- I'm not going to do anything about getting methanol in the oil, because I'm focused on running a 0.95-1.05 lambda 6.0-6.5:1 Air fuel ratio. I'm on the renewable energy side of things. We want to use methanol to replace gas on boats, because if the boat sinks, the methanol is safer than diesel and better than batteries.

@@Dr_Xyzt Only three? Here are three immediate problems you'll need to consider. First is storage, you'll burn about 4 times the amount of methanol so storage and weight and cost need to be considered. Second, methanol is hygroscopic so keeping the fuel "dry" is an issue. Third, methanol is very flammable and is hard to see when it ignites. This is one main reasons why boats like diesel fuel as it is much harder to ignite. There are other issues of course but cost, weight, and safety I believe would make methanol a bad choice for everyday marine use. It's an interesting idea from your perspective though.

@@paullatham3411 I see what you're getting at. The racer guys run a low air fuel ratio. 4.2-5.7:1, which is where the quadruple consumption comes from. -- I'm focused on emissions compliant stuff, so near-stoichiometric is a requirement. -- I'm committed to safety. Have you had any leaks where a flexible hose connects to a solid one? Have you developed leaks on vehicle tank caps or had the caps seize with corrosion? -- Did corrosion fill any of your vehicle tanks with particles? -- Has your fuel been stored for a period longer than 3 months? -- Has the vehicle sat for a period longer than 2 weeks and experienced an issue?

@@Dr_Xyzt Ok, here are some thoughts I have about this project. Us racers run about 3.8 to 4.2 a/f. At 5.7 my engine runs too hot so the extra fuel keeps temps down. (Something about 25psi of boost may have something to do with that😎) Stoich on a gas engine is 14.7 a/f and Stoich on methanol is 6.5 a/f so you’re going to need about 2.5 times storage to achieve the same time/distance calculation. And you’ll need to use appropriately sized lines to ensure adequate fuel flow. Storage: stainless steel and anodized aluminum is your friend and I use an aluminum fuel tank anodized inside and out. I use ptfe hose for my flexible lines. Also use A/N fittings so you don’t need o-rings wherever possible. If you need to use a o-ring make sure it’s viton. Storage tips: keep the tanks as full as you can. Air (water vapor) is the enemy. Make sure the tanks are air tight and sealed. I’ve stored 55 gallon drums in my garage for 6 months or so with the drums sitting on 2x4 blocks. My garage is insulated but not conditioned and I have had no problems. You have to provide tank ventilation when the engine is running but I have a ball valve on my vent line that seals everything up when I’m finished for the day. (Be sure to open the valve when the engine is running or you’ll collapse the tank. Don’t ask me how I know) As an aside I don’t know what emissions system you’ll need to address as methanol is not a hydrocarbon. As always YMMV. Cheers!

P5pppppp

The dyno limits the acceleration to 600rpm/second so they were close to the same.

@@WeingartnerRacing Thank you I couldn’t think of the term accelerated rate

M Mmmmmn

I use magnafuel pro star 500. It never hurts to have much pump.

I really don’t want to change much on it since it was really meant for the blow thru new motor.

@@WeingartnerRacing yeah, I get that - you'd just end up changing it right back...

806 heads are from early 5.7l Camaro firebird. They are supposed to be the worst ls head. They also use perimeter valve covers, different from 706/862/243/799/317. I wouldn't bother with them.

No. Get a set of used LS3 or boy a better aftermarket head. Why mess with junk?

Yeah old crt tv, windows xp etc lol

I liked 99 better than now.

If it aint broken dont fix it.

In circa 2005 they added a 15" flat screen monitor

I remember doing some dyno runs in 1992 that looked exactly like this. Other than the monitor of course.

I used three different carbs. Each for there own fuel.

@@WeingartnerRacing Thanks for this interesting comparison of fuels,

You gotta source for this? Ethanol is ethanol, even the isomer is the same.

@@timothybayliss6680yeah I thought the same thing as the chemical compound is the same, pump is all made from sugar and the race stuff is corn, pump is 107 and race is 116, all I can refer to is every time I see race ethanol its always boasted as being "made from corn" not sugar so unless they are using mtbe or something along those lines or very high octane unleaded that's all I can refer to.

@@ezmny1387 another thing you MAY be seeing. The gasoline portion of pump e85 is made with cheapest available fuel stock. The gas portion of race e85 is unleaded race fuel, which may account for most of the increase in octane rating

octane doesn't make power unless you were knock limited and the higher octane let you optimize the timing. but in this case he wasn't knock limited on any of the three fuels. I'd be more interested in the calorific value of sugar vs corn E85.

@@bradmcgrath358 Sugar vs corn E85 probably has a lot to do with the fermentation process. Sugar is pure sucrose. Corn has other things in it, and likely requires a few modifications to the formation process.

You are doing something wrong.

True E85 will make a little better power at all RPM. Sadly, E85 doesn't really mean 85% ethanol, it can be various ratios of ethanol to hydrocarbons. I'd stray away from it for carbureted engines.

Uh what? How the hell is that ? My 1990 bronco 5.0 would suck down a quart of Gasoline in 10 seconds that mean it makes 500 HP?

Theoretically yes.... if the air/fuel ratio is perfect. Where the bsfc really comes in - is when someone is trying to claim HP numbers that don't match anywhere close to the amount of fuel used. It's just another data point to take into consideration. I'm not worrying about questioning Eric's dyno results.

They keep adding bs HP numbers that will never be seen as NET HP numbers on the track.

No

Timing curve at lower rpm.

Definitely, plus, domes tend to need more timing than flat tops.

I don’t think it would have done anything but hurt it. The two degree made almost no difference

Not on this combo unless maybe q16

220

Needs ….. 😂

The dyno sheets are in the video showing the difference. It’s closer to the end. Most people never make it to the end of the video. I also say out loud the numbers and differences at that point. Got make it all the way through not first 30seconds.

Methanol carb and it was pure.

In fuel injection its fine but with a carb you will have a harder time because of the varying ethanol content.

@@taylorsrus9543 not true. My 14.6:1 565 big block runs on E85 just fine. The pumps in my area are 82-87% year round

@@Ragnarok1979 Well not everyone is in your area. Pump E85 can legally go down to 53%. and I would guess your 87% to be a faulty test. Also, not everyone has a mild setup like yours. Glad it's working out for you.

@@taylorsrus9543 you guess wrong. I know people who have tested pump E85 as high as 90%. I don't know where you're getting mild from, but E85 can handle high compression and/or high boost. The only thing special about "race" e85 is the sticker on the pail

@@Ragnarok1979 If that was an accurate test, then whatever that fuel was is out of spec as it does not meet the standards of E85 which is 51% to 83%. Mild is based on your dyno video, but maybe that was your break-in run or baseline. Either way, enjoy.
