Default Finally! Got my JE pistons today, and also picked up some 440cc injectors....

Just thought I'd share

I paid $540 for the pistons, and that includes the rings, pins, and clips.
I got them from <a href="http://www.jrcmotorsports.com/index2.html">JRC Motorsports</a>

I got a set of 8 injectors, that have about 5 minutes of dyno time on them, for $300. I can get more if anyone is interested, and cheaper, if there are a lot of people interested.

Click on any pic for a 1472x1104 version.

Da box:

Aren't they pretty?

Default damn, those are purty!

did you have them custom made to your specs? or are they an "off the shelf" JE piston?

Default Sort of off the shelf......

they are for the 2.0 ABA block, but the dish is custom specified for a 9.0:1 ratio with a 20V head, plus they are clearanced for the 5th valve.

Took them 3.5 weeks to get here.

Default I used the SWAG method.....

(Scientific Wild *** Guess) along with the RC Eng. site.

redlines1.8t is making roughly 235hp with his K04, so according to RCEng, that comes out to about .57 BSFC (using 5 bar 270cc @ 100% duty - worst case scenario)

The S4s with the K04s are making 400hp on a stock fuel system (300cc @ 4 bar) which comes out to a BSFC of .50

440cc injectors, at a BFSC of 0.50, 100% duty, will support about 390hp. At a BFSC of 0.55, they'll support 350hp.

I figure this is about the limit of the stock A4 fuel pump, so anything bigger would be a waste, until someone comes up with an upgraded fuel pump.

Another big factor was the fact that I was able to get 8 injectors for $300. We'll see how well it runs, I can always upgrade later
