Who's in for a BEGi Down Pipe?
#209
Nothing changed on the car except the downpipe and position of the O2 sensor. And the O2 sensor was just rotated 90 degrees from the stock location. No inlet tube either. It was very strange. The only difference in run conditions was the humidity level. But even then.....
We may do another dyno run on it to see if it is consistent or a fluke.

that AFR seems counter entuitive... I'd think with a better flowing downpipe you'd get leaner AFRs not richer. Unless the computer is closed loop and the O2 location made that large a difference it seems like the BEGi pipe may flow less. Which doesn't make since to me.
Stephanie, we're closing on a house on the 20th. Then I'll call you about the NC turbo I'm not allowed to spend any money until the mortgage is official.

Very interesting and mixed results. Same power #'s, but the fuel curve is very different, and the torque curve is somewhat smoother. The car went from very lean to very rich. So there is power to be gained once the fuel curve can be leaned out from 10:1.

where's the boost graph?

Power levels are really strangly consistant between DP's.

PS- Thanks for the stickers!

And the "stock" location of the O2 bung, that's down by the transmission? I haven't seen a stock pipe in about 5 years, I forget. I know the GReddy downpipe has the sensor up by the turbo, right?

I'm sorry if I'm slow here but what are these two graphs comparing? BEGI's divorced pipe against what? Stock greddy? If so, that's interesting.

BRG said he wants to tune the emanage himself. He should be all set to do so with his new wideband O2. I agree. He has the components now. Just get the fueling and boost taken care of and it should be a fun car for sure. t
I wouldnt let the dyno sway people from purchasing the DP. That's easier said than done I realize, because I know most of you were waiting on the numbers to make a decision. It's a quality piece, with a design that has proven to make good results on other applications. I'm sure the benefits will be seen when combined with the tuning needed to get that thing going strong.
