air flow through front bumper

[funkytown]

Looking at the c-west front bumpers the allow for alot more air into radiator / FMIC area, as well as the spot light area if you wanted to put coolers in those areas.

Anyone had experience with opening up a standard front bumper and doing a nice job?

pics, thoughts, advice plz.

just run no bumper on the track, save the lip

and your fresh bling paint

how about no - that makes it worse

a decent front splitter would be your best bet.

i had a look in to that idea qwerty, i couldnt see any for sale.

If your talking about the splitter i was meaning a custom one for the track.

Opening up the bumper will lower the radiator's ability to cool at high speed i.e. on the track. Having an opening in a good high pressure spot i.e. the front, that is smaller than the radiator means that the air has to slow down as the area increases from the opening to the radiator. Then it spends more time passing through the radiator and transferring heat.

I have no idea at what speeds this becomes critical though, need to find where my books have gone that had details. Think it may have been Corky Bell's "Maximum Boost"?

Also a good setup will have the opening at the front, and then ducting around the radiator so that once the air enters the bumper opening, it can only pass through the radiator, otherwise you will loose precious air around the radiator as it takes the path of least resistance.

Here's some images that I prepared years in advance; (think these are from Maximum Boost too, found them on my photobucket)

At the extreme end of the scale, have a look at the front end of a Nascar, airflow duct area for the radiator is pretty small.

And a note on better intercooler design,

but yea thats why I said no BLAZD

You may have said "NO" but I backed it up with diagrams, and tits and ass. I wish school had been that good at providing education!

amen - I woulda copy/pasted

I only saw tits and ass...

Oh wait there was other stuff...

If anyone is interested, here's the ducting I did from my intercooler to the radiator.

This means that all the air passing through my intercooler HAS to go through the radiator rather than escaping out the top/bottom/sides.

Pretty easy to do as well - just need some thin alloy sheet, tin snips, and a rivet gun

Every little bit helps when it comes to controlling temps on the track...

a bit off topic but hell, everything you do and the quality is just amazing

Choice!

And the floor is spotless as well.

Cheers man, it aint that fancy, but should definitly serve its purpose

hahaha, I try to keep my garage clean (although sometimes hard with all the crap I have laying around...)

if it was mine i would have run the top plate way down the rad to nearly half the height of the ic . as you can only get an airflow = to half the size of the ic through the ic . where as the virgin air from the grill over the top of the ic could have cooled half of the radiator as opposed to the 1/4 it goes to now
