I certainly agree. When I had the turbocharger built the operating parameter questions asked were pretty simple; bore, stroke, diesel, 1000ft. pounds torque at 1400rpm, They sized the A/R to the desired parameters as directed. A computer map was generated and the exhaust section of the turbocharger figured at a .93A/R. On a flow bench this needed altered a little to acheive the correct "zone" to keep the exhaust pulses from saturation which can break turbine fins. After satisfying the parameters for the turbocharger operation, the fuel system and timing was addressed. I didn't have anything to do with this so don't know what was done. I followed instructions installing the parts, and chained her to the dyno. What I was wanting to do is find the weakest link of a very common engine series people have in B models, and gain appreciable output power increase using this existing platform. My 711 is sound and I was not looking to "hot rod" the truck as it really is junk, except the engine and trans. As mentioned earlier my target of 300 reliable horsepower was never fully realized, but the engine makes a consistant 250 at the wheels the way it sets. This in itself is about 50 horsepower more than original design criteria for the engine. I'm happy with it as is. If I were to cut the heads for fire rings, I'm quite certain I could acheive the 300 mark and it would hold together fine. I don't have piston coolers so wouldn't want to push it really hard cause once broke, it would be fatal. I kinda put the project on the back burner like so many others to maybe pick up again, someday. Rob
