Let me know what you think. How do you guys like rear the diffuser?

Clean man. Never a fan of Mugen skirts though.

 

Looks too 'busy'
Never been a fan of the front and sides, rest looks great!

Overall, not bad.

 

looks gaudy

 

front is higher than rear?

 

The diffuser looks good. My only concern would be the forward section of the design. It looks like there is a large gap between it and the car which could cause drag. I'd love to see the piece off and on the car.

A Mugen GenII wing would really set the car off IMO. Still looking good though.

 

it looks perfect

where is the diffuser from? or is it custom?

 

Looks great. My favorite front and sides.
Was the diffuser made or bought?

AWNSER NOW !!!!!

that diffuser is beautiful , i 2 would like to see it off of the car as well

looks amazing IMHO tho

 

looks like a varis diffuser. looks good...any closer pics of just the diffuser/rear bumper area?

 

I updated the pics to include a close up shot of the diffuser.

Yes, it's a varis diffuser and I was contemplating producing a limited run of these in dry carbon similar to the gurney flaps that I produced, if there is a demand. I will explain a little bit further in the morning.

Would be interested in comparing the possible cost of yours vs the original.

 

Looks great, just don't know about that gap, I'm assuming you track right?

 

i bet it adds 20 jdm hp, right? just playing. i have mixed feelings about it. don't get me wrong, the car looks absolutely badass... and the diffuser looks like a quality piece. i just think that to have the diffuser, your car either be super fast... or you better be a super fast driver (on the track) to just back it up.

 

wheres your exhaust?

Please tell. There is plenty of interest.

 

Someone mentioned that the front is higher than the rear. The suspension was setup for the track, hence the higher front, and I didn't want to lower the front for the pictures. Maybe next time.

The diffuser is made by Varis. The diffuser appears to be made bucket and brush style (wet layup). There is one layer of CF, 3-4 layers of fiberglass, and another layer of CF or dyed (black) fiberglass. I have to be honest, this is the best wet layup piece I have seen to date, BUT it still suffers the drawbacks of all wet layup CF pieces:

lack of strength (to much resin in the CF matrix)
separation of resin and fiber over time
extreme yellowing
air pockets

If I have the part re-produced it will be made of 2-3 layers of high quality pre-preg (dry) carbon. The part will be vacuum bagged and cured under heat and pressure. What will the end result be? You will get a superior product with a lot of strength and it will be less than half the weight of the Varis product. I think I can go lower than the varis piece but unfortunately not by much, the material cost and labor is much more expensive than wet layup.

Jomama- I disagree with you. The purpose of a diffuser is to decrease lift/produce down force. Isn't that the same purpose of a wing on the back of a car. A vehicle does not have to be "super fast" to run a wing. You don't have to be "super fast" to improve the dynamics of a vehicle by running a diffuser. I wanted to decrease lift experienced at speed while not slapping on a large wing on the back. I wanted to preserve the overall look of the ITR while still improving grip at speed. Is my car fast on the track? Yes it is, it will be faster after my JRSC setup (10 psi) is slapped on. Even if the car was slow on the track, nobody should feel like they have to meet a certain standard to put a part on the car.

Morraz3- I have a turndown exhaust which exits under the car. This does reduce the effect of the diffuser at the back since I am dumping air under the car. I plan to change the setup to a side exit in the future.

 

looks good

that diffuser could be the next great "JDM" accessory

It's already.

 

car looks good....

the diffuser looks like it belongs on the back of a S2K or NSX......

But, if it works, so be it......

 

It looks like it's just in the middle not all the way across like this one:



Aren't they supposed to be all the across the bottom?

 

Here is an explanation of how I mounted the diffuser and why. This was a conversation I had with another member on this forum:

Yes, I mounted it so it's adjustable. I used 12 inch threaded rods so you can adjust the angle of the diffuser.

You want the leading edge of the diffuser to be level with the floor of the car. The diffuser should angle up at 7-9 degrees, any greater and you risk flow separation which diminishes the effect of the diffuser. I mounted the diffuser so the leading edge of the part is level with the lower suspension pick up points on the chassis. I think I might have to move it up by another quarter of an inch.

If you crawl under your car you will notice the floor of the car is much lower than the floor of the trunk. The differences in height occur after the rear suspension pick up points on the chassis. There is no gradual transition in heights, there is an abrupt change in height which causes turbulence. I have the diffuser mounted to produce a gradual transition in height from the floor of the car to the rear of the bumper.

No, a diffuser is not effective taking in "dirty" air from the wheel well.

 

Where the hell is your exhaust, pics!

 

I can't believe anyone is hating on this car.

It is quality and done up proper.
I myself am not a fan of the mugen pieces, but they are function over fashion.

Are we to assume the mods for this car are track oriented?

Is the diffuser stable at triple digit speeds on track?

I myself would be very interested in a dry carbon version of this piece.
