Allison V-1710 Engine

The first V 17 10 produced 750 hp. By the beginning of World War 11 it was producing 1050 hp, then 1125, then 1325, and late model P‑38's got 1475. But engineers recognized that there was a lot of energy going out the exhaust pipes.

An attempt to recover some of this energy resulted in the turbo-compound V1710 shown at the bottom of the page. It was identified as the V1710‑E22 by Allison, and as the V1710‑127 by the government. A turbo-compound engine collects all of the exhaust gasses and runs them through a turbine, with all of the power generated going back into the crankshaft and ultimately to the propeller. It differs from a turbo-supercharged engine, which uses exhaust gas energy to increase the pressure of incoming air. Work on this engine began in about 1944 and continued until 1946, when Allison asked that it be cancelled because turbine engines had greater promise. It was the first successful turbo-compound engine, and probably one of only three to ever be built. This engine was designed to power the XP63H, which, as it turned out, never flew. The V1710‑E22 had a military rating of 2320 hp, and a War Emergency Rating with water/alcohol injection of 3090 hp.

I get the point, but the top speed in second gear of an M6 LS1 F-Body is 79MPH (on stock tires and 3.42's).
I wouldn't say that is a long gear really....

I think the Viper only revs to 6k but uses a 3.07 rear gear. The earlier vipers only went to 5500 rpms if my mind serves me correct.

True, its been a while since I had a 6 speed ls1 car and even longer since I had one with stock gears but the vipers redline is about the same as the f-bodys... around 6,250. But I do knwo what the OP is talking about, it doesnt feel like its pulling that fast until you look at the speedo. Maybe our buttdyno's are broken

I think that is probably one of the biggest reasons it didn't impress too much.
I know it takes a decent amount to impress me since having my old T/A.

Ride in a 630rwhp cobra intrigue you?

If its not over 630 he doesnt want a ride.....lol

Me on the other hand HELL YEAH!

Early prototype P51 Mustang fighters were tested with an inline engine.

The entire plane was designed and built, and flown in ~115 days.

That was before the Allison "V" type..

The Japanese also used inline piston engine aircraft in WW2..

As well as "inverted" "V" engines..
