I bought an engine from RY and I changed nothing except the exhaust headers. they complained because I put it on a chassis
dyno and did some pulls. they recommend that you run their engines at 8500 RPM. I could of run at Hartford or I-96 30 laps
at 8500 RPM's and it would of not been a problem. But the fact that I ran an 8 lap engine with a different header and it blew
up and broke cranks in the engine was an oiling problem. it wasnt a heating problem. Ironically this happen on two engines
back to back. If RY would of had a chassis dyno I could of used it. I only stated that I bought $100,000 in racing engines not
to impress anyone as I have bought $250,000 in engines for others same year. It was what i would of expected. But they
seem to me trying to find excuses not to help. you buy a $30,000 engine and turn it 8 laps and it blows up and what you
you say. The reason we used the chassis dyno was to solve a ford problem where the chevy had tons more low end torque
and could get off the corners, unlike the Chevy's. Roush Yates was to use the TRU-Y's and that non sense in the end. If you
want to make a ford work find a big track and dont get less than 5000 RPM in the corners. Suellen Wilshe
I agree that once you let another engine builder dont expect much from the first. One was never change and the
other was. I am referring to the Roush Yates never touched engine. Now of the other engine we were trying to
fix a design flaw in the water pump area. the reason we went to Gaerte on the engine they changed after 2 years
of experience we found on dirt and asphalt that Roush yates engines had alot less torque and could not get off the
corners even when turn 8500 RPM's. The Chevies pulled us 3 to 4 car lengths of the corners. But Fords have never
been know for torque but they have great top end if you keep they wound up.
