New air box for TM member
Turbo Mini Forums

brilliant

Really cool skills. Nicely done.

It's similar to an oil cooler shroud I made for my mates 300bhp cvh rs turbo about 10 years ago!



infact, I have the mould somewhere...................

This is FORD country, on a quiet day you can hear Vauxhalls rusting.

Here's some pictures of it fitted to the car. Hope you like it and thanks Steve.

Chris answer ya phone

I seriously doubt it!

Looks lovely!

I'd say that the hose is too small.... I'd GUARANTEE that that set up sacks power. Sorry.
Nice work though :)

how so? through testing or some other reason?

turbo 16v k-series 11.9@118.9 :)

Well the hose is the same size as a miglia one and as evo said we will see through testing. There is a plan to make it into just a cold air feed if it does sap power

I think he's being sarcastic regarding hose size ?

9.85 @ 145mph
202mph standing mile
speed didn't kill me, but taxation probably will

Not being sarcastic. If testing, perfect. If you calculate how much air going in there at full chat, you'd be surprised.

Yeah there is a plan to put a relief hole in the other side if the engine is suffocated. I've seen it done on miglias so the box won't be ram air and cold air but will just be cold air feed.
You can't see in the photos but there is a large scoop at the front

That hose looks large enough to flow at least 300HP...I'd love to see a N/A A-series run that to its limits!

The formula student lot pull 75hp through a 22mm or so inlet.

I think you'll be fine.

@100mm the pipe has an area of flow 3x larger than 2x 40mm venturis.....it will be fine, fine, fine....doutzen fine.

lovely bit of work steve.

the pipe looks fine ,only restriction I could imagine would be the bellmouth to wall clearance , I prefer 2 times carb bore in that crossflow design ,so the back inlet gets a good share .but if its proven on the migs ,job done .

Medusa + injection = too much torque for the dyno ..https://youtu.be/qg5o0_tJxYM

I do agree that a smooth wall hose will help massively. That spring reinforced convoluted stuff makes the flow very turbulent.

Thanks guys, but I had a quick search last night and couldn't find anything labeled 'smooth wall' could you point me in the right direction??
The stuff I'm using has a inner core that's smooth with the wire on the outside.

I think that what is meant is simply just a hose without the convoluted type wall, I.e. A large silicone hose would be a 'smooth' walled hose. This would stop any turbulence as Tom says and potentially aid air flow speed.

In general I have always been steered away from using 'Donkey dick' convolute type ducting hose for any 'closed' engine air inlet related feeds.

By 'closed' I mean any feed which is fitted directly to the plenum or carb / throttle body, i.e. not a cold air feed which just leads / points in the vicinity of an inlet / filter.
