Drivetrain DFIC numbers
Just to follow up..
I looked under the hood of the JP. The IC looks stockish except it covers the spark plugs... I didn't get to measure if it's any thicker, but I don't think so.

Just did the install
took about 45 min, including trimming the scoop. I mounted the foam to the IC so I can switch back and forth more quickly. It doesn't look as good that way though....

Drove around a bit this evening...
but had the wife and child so I couldn't really hammer it. Felt good.
I know this is just a teaser post..... But I have to post SOMETHING
every now and then.

Just to tease you all.
I just did the pressure drop data on the DFIC, not what I expected at all! But this is the ultimate tease... I have to go to dinner (Spago's in Palo Alto, yum yum) and I didn't get the graph done yet.....
Ha ha, made you look!
Matt
ps, I'll post it later tonight. temp efficiency to follow soon.

well, the wine parings were excellent.
I had a wonderful salad, a pretty nice piece of salmon, and a good granita, but I gotta say (and my wife agrees) that my granita is better. But to be fair, I have to clean up the mess at home, at a restaurant, you just leave it and go! Gotta love that.
Well, here's the deal. I haven't posted any data yet because my wife has had a lot of shifts at work,, and Alison (my 21 month old) isn't into testing cars yet.... So there went a few days... Then I made some brackets for the DFIC. I have a polished one, and it likes to move in the stock boots. Just finished those today. Then I did the tests...
And the results for backpressure only:
The DFIC has more of a pressure drop than the stock unit. But when you look at the turbulator density inside the unit, it's not surprising.... I was thinking that this would have similar results to the Alta flow-through. Guess I was wrong! This is a perfect example of the effect of extruded turbulators on pressure.
Before everyone draws conclusions, please remember this is only half the story. With the thermal efficiency numbers, you can figure out the density change before and after the IC. With just this data, you don't really have anything to conclude....

Matt,
How much of the pressure drop is due to the cooling of the charge post-core? It seems that a cooler charge post-IC will show a higher pressure differential, just as a higher resistance will increase the pressure drop. Right? Either way, lemme just say....Thanks for the work, man!
