Remember the pics of the 2.5 fiesta st?

well did some more mapping on it last night:



not finished yet, just goingto purchase some vernier pullies for it to make altering the cam timing easier to see what we can do...

but 297bhp and 229lbft for a NA car is pretty cool!

More than 100bhp per litre is decent in my book.

Thats excellent power/torque.

as said above needs more time yet, but adjusting the cam timing on these without verniers is time consuming.....

thats the characteristics of the torque curve, the torque does drop off before the rev limiter........
