Let me see if I can elaborate on what Im talking about. Ill tell you a story on where Ive seen this, Lets compare two fuels for a comparison lets say the 50-50 ethyl supreme, and Oh, why not have some fun and talk about Methanol(Alcohol)! I've had the privilige of making an updraft carburator run on Methanol, and run good on it. When I first started pulling, I used Methanol for fuel in our tractors, Then once we started winning when it all came together and consistancy, balance, and the perfect torque curve and going the distance to win, the club outlawed the fuel, right after our first pass, after the class had started. DQ! Thats a whole different story,,,LOL Anyways, back in 99, I put my 40 Farmall H on Methanol. At the time, it sported a 270ci engine, 285 compression, custom grind cam, 8043DD cyl head, milled .050, ported, polished, so was the intake, and a 450 carb. On the 50-50 "Ethyl Supreme" mix, it was solidly 95 hp at 540. When it came down to 540pto rpm, it shook the fillings out of your teeth! Not cause the engine was not balanced, (cause it was!) It was because the H would create so much torque, Id call it, explosive torque, it would get the needle to 95, and it would do it really fast, It jumped HP so fast as the rpms got higher. When the load was put on that engine, it wanted more. Imagine, trying to drive this tractor on the track, just a touch of the gas, and you came to a dead stop from it breaking traction. I give it a foot, it would take a mile. I guess, going from stock engines, to smaller stroker engines, then, this powerhouse, I found out, it took more than just sitting on the seat to get it down the track. One season, I decided to go to a local pull, it was a sticky track, but, it would not take torque, it would come out from under your best cut tire,, spun out. Few days before the pull, I remembered that I had a few gallons of Methanol left over,,,,, going to waste,, and sheer bordom one nite, Long story shorter,, Something Wilder was an Alky burner for a one time deal. When I ran the stock engines on alcohol, the hp darn near doubled, and it had a real nice, smooth acceleration, slower, but, it was consistant,, when the torque came on, it seemed to always be a the same steady pace. It would get there, just was less erratic. Something Wilder's HP did not double, it did increase, quite a bit actually, 35 more ponies at my command,, But, when it was lugged, the engine seem to settle down, Where, before, it was very quick to get to the 95 bounce from 94-then 95,96, 95-96, dyno needle jumping,, fat hp come on when the load was aplied, On the Methanol,, when the dyno wheel was turned down to 540, the needle would move much slower, but the more the rpms dropped down to 1815, it held more hp more steadily, consistant, sure, it was stronger, but it was slower. over the rpm span from wide open throttle, to full work load 540, it took more time to get the hp up there, but it would get there,,, just took a bit longer,, Smoothed this engine right up on its power. And of course, if you've ever heard an alky burner run, it sounds quite interesting,, different,, very raspy, sounded like one of those top fuel dragsters. So, on the track, they pulled heavy to light, and I started out in the 5500 classic. Wilder was in 3rd gear, bout 150 feet, track was kinda loose, but was still moving forward,, wheels was not pounding the track and busting up the surface, I gave it some gas, like I always did, was thinking it was going to be a shorter run than I expected, Wilder slowly sped up, HMM,,, usually it would have spun out when I did that, bout 200 ft it was working the engine a little, and the ground speed was slowing down, so I gave it about 1/4 more throttle, once again, it slowly took off, smooth transition to the rpm increase, tires took yet another bite, and down farther it went. In the case where Id be fighting it to keep hold, increase, decrease rpms,, to get the tires to grab, this time round, they just bit, the engine was not blowing the power out from under the wheels from erratic torque condiditions. Very easy to drive that H that nite, took 4 first places that nite with Something Wilder, just was very consistant with the conditions of the track VS the engines torque to tire bite ratio, you know,, the perfect rpm where the tractor is talking, the rpms are right there where you set it, till the load increases, give it throttle and go down the track, not spinning, not stalling the engine, just, a good steady bite not digging the track, and putting all the clay in front of the pan. How was the power you ask? ran 2 open classes that nite, in the 5500 open, ran 4th gear, half throttle then 3/4 towards the end of the track, never dropped rpms, never lost the bite as I tried to increase torque and rpm and ground speed, rpms slowly increased, rather than snap, it was there when I accelerated. Was a pretty loose track, ollies spun out 20 ft back, lots of dirt in front of the pan, all that big faster hp kicked them in the butt,,, Give an engine consistancy, it will give you a reliable return. That was my experience with running on Methanol Alcohol back in my earlier days. ChadS
