Thanks Jeff I already added the fuel pump and did exstensive dog house
mods to get plenty of air to the engine. I think the engine rebuilder
has this thing tuned down to make the sure the warranty is not needed.
I am being quiet nice on the break in.

Thanks

Jim

Do you have a pyrometer? If so, what are your EGT's? I noticed that
overfueling on mine produced dangerously high EGT's.

First step is to remove the aneroid from the pump. See how that works. I see
12 to 13 #s on my 250, that will vary due to ambient temperature and engine
speed. Make sure you have absolute full throttle opening, it's common to have
problems with that adjustment, the trans cable travel and the throttle pedal
stroke can be tough to get right. You want full travel on the injector pump arm
and all the travel out of the trans cable at the same pedal position.
Frequently the trans cable will be at full travel and keep the throttle arm on
the injector pump from opening fully. I removed my muffler and increased the
exhaust pipe diameter to 5", easy to do and the noise increase is negligible, if
you want power you must smoke. However, too much fuel can cause the EGT to
soar, and you don't want the pistons melting and coating your exhaust system on
the inside. Pyro readings should be limited to 1100 degrees, probe located 6
inches behind the turbo charger outlet. If they exceed that level on hard
climbs the pump should be turned down or a charge air cooler should be
considered.

I recently installed a new 3208 250 HP in my 82 FC. I am currently
getting 10 psi of boost after turning up the fuel to boost pressure
ration on the fuel pump. I still think the engine is not putting out
and was wondering what boost pressure other owners are getting for max
boost pressure on the 250 HP. Currently the coach is not sending cat
black smoke out, and it is kind of nice not having people look at me
like I just cut down the rain forest.

Any input would be appreciated including tricks to max out the power.

Thanks,
