There's no way the car is usable on any track, anywhere in the UK with that noise level lol. Not to mention the wife would disown me. (swings and roundabouts I guess). :D

Gotta laugh at people thinking they actually gonna notice a 6bhp loss on a 440bhp, almost 2ton car

Human dyno is obviously the most accurate device on the planet lmfao

Even funnier is "ram-air" :D :D

I'd have thought if you can get on the track with your non res decat milltek then the Tubi should be ok too; I don't imagine yours is quiet enough to use on any track with noise restrictions or can you pass some?

Most people with Revolution intake have CAF, which makes "heat soak" almost irrelevant.

Actually, let me clarify that :)

Without CAF, the issue isn't really heat-soak IMV. It's just already hot air from the engine bay getting drawn straight into air filter, whereas with stock it's effectively sealed from engine bay.

With CAF, when moving, cooler air is directed straight at the filter so that less hot air is drawn from engine bay.

I'd say heat soak, is more why the inlet manifold gets hot - the ambient heat of engine bay + conducted heat from cylinder head.

To remedy this, somewhat anyway, get your manifolds zircotec coated

At the price to remove and refit the manifolds alone, then the £900+ for zircotec coatings, it'd be easier and (about £2k) cheaper to just refit the stock airbox with a CAF :p

For performance the stock box is by far the best and by adding a CAI you will enhance the current setup with the additional cold air and also the ram air effect.

The Carbon system add nothing but looks and sound, and although as a kid I loved that induction noise (and to be honest I would still love it now) but I see little point in spending all that money getting MRC to drag every little ounce of power out of our cars only to slap on a nice look and great sounding over priced induction kit and loose power, just don't get it :?

the way I see it is if you planning on using the car for track days then fair enough,you gunna need as many horses as possible but for day to day usage I think loosing lets say 20bhp and having 400bhp left and a nice sound is enough for me to keep the pipecross.

The ram-air intake works by reducing the intake air velocity by increasing the cross-sectional area of the intake ducting. When gas velocity goes down the dynamic pressure is reduced, while the static pressure is increased. The increased static pressure in the plenum chamber has a positive effect on engine power, both because of the pressure itself and the increased air density that this higher pressure gives.
