20Bhp from Exhaust and BMC CDA

Have been having a bit of a disscussion with a Punto HGT owner over on fiatforum:

He reckons to have got near 20Bhp extra from his exhaust and BMC, surely not??

From my limited understanding of engines it just seems to be unreasonably high for those two simple mods?

Anyone agree / disagree with me?

Does seem high but it depends on what it was standard really....if it was high as std then it could be possible that it would make a fair bit with exhaust/bmc.

Yer asked that, said it was 133 before mods. so about 17Bhp increase, still high I thought!

This should probably be in other marques, sure someone will slap me for posting in the wrong place!

i can imagine only that sort of power gain from a simple mod would only happen of something like a skyline....would it???

Dream land imho.

8-10bhp maybe from a BMC + decat + System.

Id say a good gain from an exhaust and BMC is possible. Maybe not 20bhp but still a big gain. I had an HGT before my Ibiza Cupra. It had a BMC filter and the exact same Abarth Cup exhaust that Andy (nwmlargee - the guy with the car in question) has - i sold it to him. Although I didnt have the car rolling roaded, I managed to do a 15.4 second quarter mile @ santa pod. There are a handful of HGTs about that are noticeably up on power than the quoted 130bhp factory figure. I feel that mine was definitely one so Andys could be a similar case. He did not have a rolling road done before the mods so whos to say the car wasnt running 140+bhp as standard?

Might be restrictive as standard or knackered
