Anyone notice better airflow or times with a rear difusser in there rear bumper? also post some pics if possible.

 

It mostly made a difference on re-entry from space.

 

here is apic of the golden eagle one. not on a car but for sale..

 

WHAT rear bumper?????



Was worth about .3 seconds on a 135 hp D15B7.

 

the rear bumper creates that much drag???

 

nice TIP..

 

I did not use a rear diffuser, but chopped off the bottom part of my rear bumper and gained 4 mph on my trap speed. My E.T.'s did not drop do to traction issues off the line.

Do i think it works? Yup. Is it worth the price? No, I would just find a spare bumper and chop off the bottom section.

 

mike,how much for the diffuser? pm me. thanks

 

3" Hole Saw...

 

hummm. what else can we hack up to go faster?

 

cut the roof off, like sport compact car did to the nissan, or whatever car that was

j/k

 

Passenger floor pan........who needs it?

<---Pulling out the plasma cutter...

I think Im just gonna do the hole saw thing. By the way for those with EG's, the VX hatch had a factory panel that covers the underside of the rear bumper on the drivers side. Im looking into finding one of these--well actually I know where to get one just havent picked it up yet.

Hole saw solution:

 

Hey exo,did you use a 3" hole saw also?Is that the think you make door know holes with?

 

I used a 3" hole saw to free up my air catcher. I have also seen some NA cars with aluminum panels on the front and rear under sections. Did anyone else see that Hocus Pocus car? If anyone wants to make one I know where to go.

I believe there were a few kinds of 3"hole saws u can get. some are for wood, some are for metal. jus a bit thicker/stronger material for the metal. Got the metal kind jus in case had to use it for some metal applications. cutting that bumper is like going through butter man. its the easiest modification I have done haha. i would done 2 more holes though, but it was the 1st time i ever tried it.

heres other pics of another car i tried it on like 3 yrs ago.

 

anymore pics...of the girl that is?

HAtch4ursnatch: I thought I'd throw the chick in also. I was gonna cut her out of the pic, but the pic looked better with her in it.
I wish I had more pics of her.. hehe jus luck that she was in it.

 

i actually think it helps a little. most street cars do not go fast enough but every little bit helps to fight for that .1 of a second and MPH!

 

every little bit helps it all adds up in the long run

How you think I got my stock Z6 with bolt-ons and juice into the LOW 13's?

Who runs 60 psi in the rear tires, 155/80/13's????
Lawn edging front air dam?????
no rear bumper?????

BTW I play $1.50/pound for Nytrous+.

Those 3 mods alone are worth .6-.8 seconds on MY 13.1 SOHC Civic. The little things add up.
