hi my mate claims his focus rs is 280bhp, its got collins power chip, magnex exhaust and decat, baileys dumpvalve. is it posible to get this bhp with these mods only?

 

More like an honest 250bhp.

 

yes, ours made 288bhp with dreamscience, ggr filter & mongoose pipe (still had the cat on it aswell)

 

i can vouch for that guzzler ive been in yours

 

Hmmmmm - although all depends on how the chip has been mapped & what rollers it was on i guess although 65bhp+ over standard for those mods seems a bit more than what those mods would normally provide i.e 260/265 maybe

 

Dreamscience just gives a big spike of power then dies off, thats how you got that figure...
