I agree i have learn more... and after thinking this over, here is the plan:

since the engine is barely run-in, i will try to tune the minipipe by shortening the header to see how much rpm i can get from the setup... can anyone tell me what i can expect with this engine on the f-16?

then i will try to raise the ex port a bit and see what happens....

if i screw up or if the plane is not fast enough, i'll get a Jet

thanks to all for your replies,
cheers Vasek
