Matching Inlets

[TheCAB]

Hi,

I have been looking at the claimed increases in bhp from “ matching inlets” on a Clio Cup 172 of some 10bhp.

Looking at the “minor” mismatch between gasket and inlet manifold this seems a large increase in power for such a small port blending exercise.

Is this 10bhp increase just anecdotal, ie has anyone had there own car dyno’d to benchmark and then matched the inlets and had it re-dyno’d (on the same rolling road) with a resultant increase of 10bhp, or is it really an urban myth.

I wouldn't think 10BHP is realistic to be honest. I'd imagine the car would be nicer to drive etc & maybe give a few ponys but not 10.

Maybe 3 or so.

10bhp claim is just totally ridiculous!

Maybe 1 or 2 if you're lucky..

Makes the most difference on a ph1 which has dreadful quality castings. maybe 5-6bhp. The rest of the time, you're really trying to improve the midrange

Thanks for the quick responses, in line with my thoughts on the matter.
