Induction Help

[AL666]

Hey up, I'm trying to redesign the induction system on my Rover 216 Coupe, now I know it's not really in the realms of most of the cars in here, but I'm a poor student, and I was wondering what people's advice would be about filter placement and hose sizes?

I've currently got a conical Green Air Filter in the standard air-box with a cylindrical stainless cover, getting a feed from the grill through 55mm ducting, but it has to go a long way around (about 4') from the grille to the airbox.

Would it be better to have the filter behind the grille (with a heat-shield between it and the radiator) and have a long hose going from there to the air filter (about 6' needed), or keep it where it is, and what size hoses do people think I should use for maximum air-flow/pressure combination?


Thanks, sorry for the long post,

Sorry for the hi-jack

I have Typhoon type air intake in carbon fibre if you interested
I was going to use it on my Caterham, I changed my plan and don't need it any more.

Drop me a line and I'll send you some picks

I'll also will have a 52mm tb available soon

Well, I've only just bought this Green Air Filter, so I've not really got the spare cash at the moment, to be honest, just trying to make the best of what I've got... I've already got a 52mm TB too thanks.

I dont think any induction mod is going to make any noticeble difference - so I wouldn't get to hung up on it. As long as youre not breathing hot air in from behind the rad, you should be fine. I have the ability to datalog everything on the car, so moving filters around, putting more water in the charge cooler, adding bigger radiators is all proven to either work (or not work - as is the case often).

This is really bad placement, resulting in inlet temps of 90'c


They live under the inner wings now - usally a few degrees above ambient. It didn't turn the car into some wonder rocket-ship.


I have tried them cable tied to the front bumper, with only a few degees diference in inlet temp.

OK, thanks for the help, I won't worry about it too much then...

Have you been monitoring pressure drop as well as charge temperatures? Those lengths of convoluted tubing doesn't look brilliant from the point of view of air flow.

Those hoses are from a ford mondeo i beleive. Your'e right that they aren't ideal, but they are 3" diameter and the compressor wheel is about 2" - i would of thought any pressure drop would be minimal - a couple of Kpa maximum - which is tiny in the grand scheme of things.
