My engine has sloppy 154 lbs ft at 3500 and a peak 165 lbs ft at 5500.
Peak power at 6100 ? 178 hp.
Bore 88mm, stroke standard.
Cast iron head, with standard diameter valves.
Cheers
Chris

Betreff: Re: [Fot] 89MM piston question
I do have an engine that produces 186HP per liter?the one in my 750 MV Agusta
Senna. 140 horsepower at 12600 RPM. I promise you that every one of those
ponies counts. 60 lb-ft of torque at 10500 RPM. Scares the crap out of me. I?d
buy that a TR motor could produce 200+ HP if it revved to 10K. Failing that,
not so much. Certainly not with a two valve, non-crossflow head with cross
sections that looks like the casting was molded with plumbing parts. 200HP at
6000 rpm is 175 ft-lbs of torque. I think the most recent engine build for
Peyote by Tony Garmey at Horizon Racing was about 140 ft-lbs peak, and it?s
89mm with all the goodies.
It always puzzles me when people say that. Horsepower is torque times RPM (and
a conversion factor). Torque is horsepower/RPM. So how can one count more than
the other?
Its the torque that counts. So, I suspect the motor enhancements took the
benefit of the tractor stroke. If the motor is able to produce that power
at 6k rpm with shift at 6500.
I shift at @ 6200 - my motor produces max power @5800 on the dyno. I use a
kastner designed cam for which I have the masters.

What kind of modifications were done to the engine to extract over 200 HP from
a tractor engine? Nitrous shot.
All of our FIA race cars are running legal 87mm engines.
Just rolling roaded the latest SLR build at well north of 200bhp

If you really had serious compliance with most group's rules, I would guess
half the TR cars would not pass muster. Let's have fun together.
Indeed there are Glen.

everybody else seems to be using 89.
HaHa not everybody, rules say 87mm, there are still a few guys running them
(and winning)...

I've always used 87 MM due to the rules but everybody else seems to be using
89. The procedures are the same so It'll be the same. I blew a head gasket last
time out, compression into the cooling system and blew off the bottom hose. I
guess it wasn't tight enough, and scuffed two pistons before I could shut it
down.

Bob,
It is definitely necessary to make that modification to the liners. The relieve
should correspond to the shape of the combustion chambers : about 4 mm wide on
a 89mm engine.

Do the guys running the 89MM pistons and liners need to relieve the liners to
clear the intake valve, or does the extra MM make the difference?

On Tue,
