Our 5000 Horsepower on Methanol tech manual features specs on some very high output methanol racing engines. A 6,000 horsepower combination is detailed on p. 132. It is based on a top fuel drag racing V-8 long block with two stage compressors. A minimum fuel pomp size is 32 GPM at 4000 pump RPM. Boost is 7 atmospheres. At a mechanical compression ratio of 10 to 1, approximately 0.23 cubic inches of fuel volume occupies about 4% of the combustion chamber volume at top dead center. Going up in boost with more fuel pump can yield 12,000 horsepower also featured in this section.
Several 5000 horsepower combinations are described in Chapter 28 including Gene Sharber’s tractor pulling two stage turbo methanol engine combo gets 110 psi manifold boost.
Other high output engine combos are featured in appendix 29. highlights are the GM Ecotec drag racing 4 cylinder at 1,450 HP and Smokey Yunick’s 209 ci turbo small block pulling 1,200 horsepower for the Indy 500 We thank GM Corp and Carbon press for insider details of these combinations.
