JDS:

^ Maybe.

If the scoop was a straight through hole, no change in shape, direction, cross section, good exit, I’d agree. But it’s far from it, it narrows/shallows quite well across the roof area, then suddenly drops to a tiny cross section inside the rear clamshell with a big sudden step, does 2 tight turns, goes back to an even larger cross section than the air intake in the roof and spills the air into the engine bay, which struggles to exhaust the air out through the engine cover at the best of times, and then hits the front face of chargecooler casing - in Ade’s case at least. It’s pretty much worse case really.

If you want to have a laugh, put an airspeed gauge in front and behind your intercooler and go do some speed. Put it in various places across the core, and see what the speed of the air going through your intercooler is.

No one really knows what’s fully going on around the engine bay of an Exige, except maybe Lotus and they’re not sharing.

Lols on the F1 comment. Why are we using 4 cylinder road car engines from a Japanese warm hatch with an air pump on? Because we don’t have the budget to put £200k of bespoke engine and £60k of bespoke cooling kit on our cars.

Even you are saying some air is going through the roof scoop…and the effective area is reduced by that small amount. I was also assuming that the back end of the Mohawk scoop was not connected to anything since you’ve stated that you were not using it…that would allow even more air through the Mohawk scoop and reduce the effective area even more…

It doesn’t make sense to me…but your car…

Well it seemed like a good idea at the time LOL

not taking the scoop off I like the way it looks and it makes it look like the Exige it is, not some form of half bred Elige (Sorry JF)

I might re open it if I ever get the time to route the air intake to it in the vain hope to calm down some of the SC whine setting off the noise meters at Donny, not sure that will work, but I do like to try stuff out sometimes…

That is what my plan is! I want the air intake to the engine to be the Mohawk scoop and use the large side scoops with 4" ducts to cool the intercooler…
