this is just shocking! although its made me laugh quite alot
The 1.8 has 133bhp as standard, RR statistic's shows they usually produce around 140bhp...
The K&N will zap power from it..
The exhaust will only give about 5bhp being maybe slightly more maybe less depending on the standard of the pipework?
And they remap is only 12bhp?
So if we do the maths and say hes standard unit has 133bhp + 5bhp for the exhaust and 12bhp for the remap = 150bhp
even if hes varient produces 140bhp as standard he'll only get = 157bhp
LOL!
EDIT:
although if he had this induction kit and ashuming hes varient produced near the 140bhp as standard he could get a 150bhp alone with the induction kit, read here:

so with this then if you add the 12bhp for the remap and 5bhp for the exhaust thats still only about = 167bhp! But would variey on each engine, like i said depend on the varient output as standard and only a RR could tell you the real BHP!
