what sort of gains would i get from..

ashley 4-2-1 manifold
ashley full system
k&n pancake filter
skimmed and port&polished head

 

id say ull prob get 110bhp at the fly bout 79-80 at the wheels

 

75 at the wheels standard arnt they?

wouldnt it be about 95/100 at the wheels? ish

 

an rs turbo only has 95bhp at the wheels

 

sorry got that bit wrong rs turbo has 110bhp at the wheels

ull prob have a max off 85bhp at the wheels

the less power u have the more drivetrain loss u will get.

an xr2 engine has 96bhp standard an with the above (with proper headwork) i reckon that 110/115 should be seen and add a better cam to that with adjustable pulley 120/125 has to be quite realistic, add twin 40`s again all proper setup and 140+ is on the cards.


i had all of the above in my xr2 but it was never dyno tested but i know it was fucking quick for an xr2 and sounded beautiful

 

My xr2s running ashley 4 brancher, kent fast road cam, pulleys, 4 speed box and its fast for a 1.6 cvh aswell, i reckon youll be hitting 110-120 bhp.
