5000 hp on alcohol

Have any of you guys read this book? Is it worth the 80.00$?
Thanks

 

Yes, and his other two books are good reads also. Makes you "think".....

 

I have one for sale $50

 

I gave the "first" book away!

 

so what are you saying is it worth 80.00 are not (lol)

 

Put another fuel system on it and put it in a tracter puller? http://www.sassyengines.com/

 

If you are a technical minded person, you will love the book. It gets pretty deep and intense in parts. The math and reasoning is worth the 80$. Its a great read.

 

Thanks for the info

Thank you much

 

I like Bob's books......helps you to understand the "science" to fuel systems. Like any advice you get for your race car........Take it in and make your own decisions.

 

book author response

Thanks for the great comments. When this book was started, sources of methanol info like the octane rating & dissociation in boost & compression were few and far between. And a lot of misinformation as well (like the octane rating, spark advance). The search & sort out task for the final product was monumental. A lot of info like air to fuel ratios, hot plate ignition, vaporization, ignition polarity shift, and many more were buried in complicated tech sources that took many all nighters to sort out. Keep in mind there was no single source available to start the development of the technical info. Since then I have a lot more info for more tech publications. But they are really tough to write and get through edit.

We recentlY added terms & names indexes (that you can download) to locate info throughout the publication. The terms index is 6 pages single space that provides an indication of the materials in this 300 page reference. The indexes should help to locate all the info about specific topics. Current new printings have the indexes.

The temperature potential of methanol combustion with oxygen in a vacuum without heat sink losses is way above the melting point of even the highest temp ceramics. Racers are extracting only a small portion of the energy from the fuel in our aluminum, steel racing engines. An outlaw promod builder recently told me he dyno'ed 2500 HP at 25 psi of boost, black tracked at 35 psi of boost, with turbos good for 50 psi of boost. The math indicates a 5KHP engine.

Screw blowers and some great Roots blown Outlaw and Pro Mod efforts aren't that far behind.

ps The cost of a reference book is trivial compared to the cost of running one of these racers, especially if you make a mistake that added knowledge may have avoided. The field of methanol combustion as well as other fuels covered on in this book is so vase that we basically only opened up the technical side of it. There is so much power made from high compression, high boost, made possible by rich mixtures; and power loss from excess cooling from those same rich mixtures and the nitrogen in the air that we are just beginning the understanding. Plugging parts on and off your engine trial and error without some science to see if they work is way more expensive.

Thank you for reading.

 

I love your book Bob. Still reading and reading again to the point my women thinks I am nuts. When you stated that A/F ratios of 3.8 you torched a piston I could not believe what i was seeing. I would have thought at A/F ratios 4/0 you would have been safe. Being a 13B rotor head I will give 3.5 ago. The other thing is all you guys run Supercharges with cubic feet of air. Us turbo guys are all useing LBS of air which is hard to cross referance on Spud Millers calculator. Anyway Great books, just need to get my maths heaps better.

 

May be reading this wrong but this don't make sence to me


"with oxygen in a vacuum"

 

Sorry try 4.0/1 afr. good pick up.

 

Cross referance

one cubic foot of air weighs 0.081 pounds at a temperature of 32 degrees F, or alternatively one pound of air equals 12.4 cu. ft.,

 

Ha, there is a God and he goes by the name ( Marklee). Thanks a lot for that cross reference, now I can go back to spuds calculator work out what a GT40/94 pushing around 80 lbs of air will support in a 13B rotor using 1.6 lbs of fuel per H/P. Thanks again Marklee.
