is my puma too slow
bought me a 1.7 puma last weekend and the stats claim 126 mph but mine seems to strugle with 100.the exhaust sounds like its blowing but took it kwickfit yesterday and they said it was fine.i think it might be blowing at the manifold? anyway it dont seem to wanna go over 5500rpm
in 4th im getting bout 95 at 5500rpm
in 5th im gettin bout 105 at 5500rpm
its still very fast at getting there but seems too slow top end to me.

Had this happen on my 2 litre Zetec Mondeo with the same symtoms as you describe - lack of performance + exhaust blowing noise.

ps. Yamaha, jointly designed the Sigma engines with ford, its not all their own work
Interestingly, have a look at, and take some measurements from a 1.6 twincam from the mk1 toyota mr2
and compare to the sigma

Yahama designed the 20v head on my 4A-GE engine, good bit of kit.

i had this with my 1.8 xr2i!
i did the decat removed egr and still was going slow
and in the end some previous owner had put new cam belt on and the cam timing was miles off!!!
so while the lid was off i put in some 2.0 ones
check ya cam timing!! and double check!!
