>Boy, I'd like to see the 130 hp DSP X 1/9.
>As the owner of an '86 Fiat/BErtone X 1/9, DSP, EFI/DFI set up by Steve
>Hoelscher, with spring set-up by him, modified manifold, etc. and his
>co-driver for the Solo 2 Nationals from '95-2000, I think you're way off
>On a chassis dyno, the X he has is putting out 77-78 hp at the rear wheels.
>Understand, the X 1/9 is an 8 valve, non-crossflow SOHC engine, with very
>cam timing, 8.5:1 compression and no tricks. Stock EFI X 1/9's in the USA
>were 75 hp at the flywheel. Steve's done a hell of a lot to get slightly
>above that AT THE WHEELS.
>A Prepared X 1/9, under the Prepared auspices might put out 130-135 for the
>best engine, at the flywheel. Compare the horsepower, and yes, the X 1/9 is
>down. The area especially down is Torque. The X 1/9 is a 1498cc motor, with
>86.4mm bore, and 62mm stroke. This is a large improvment from the 1300
>motor, which is actually 1290cc, 86mm bore, 55mm stroke. That's 2.2 inches,
>so the 1300's revved but didn't really do much. And only the '74 1300 is
>slightly lighter than the later 1300 and the 1500's. At the Pittsburgh
>National Tour in '96, my '78 1300 weighed 2117, with a roll bar and carbs.
>Steves 1500 is @ 1950 pounds, and the weight differences can be made up
>with drivers. If you know Jean Kinzer, having her drive the car would
>vastly improve the power to weight ratio, rather than having a large person
>driving. Seat changes, and other items help to lighten it as well.
>1200-1300 pound Neons? Not likely, how about @2300 pound Neons?? [How
>about it Neon folks?] Since the DOHC motor puts out 150 hp flywheel, yes,
>170-180 would probably be possible in SP trim. Even though the weight
>difference is not great, the Neon's got scads more torque and hp. It's not
>however a mid engine, with the low polar moment of inertia or low center of
>My 5 cents.
