In the first pic above you can also see the MITUSA fuel pump. Opie now has a mount, so that people running a fluid dampener, and twin CP3's, can run the MITUSA. I no longer have a fuel supply problem.
As far as what I noticed with the coolant bypass. I notice that going down the track, the coolant doesn't rise as much as it did before. It amounts to about a 20 degree reduction in temp at the end of the 1/4 mile. In normal driving the coolant temp is more stable. I don't see the thermostat cycling like I did before.
Another benefit I noticed, but didn't tie it to the bypass right away, is that the transmission temps didn't get as hot, and cooled down quicker. On the 05 I still have the heat exchanger, because it doesn't have to be removed when you install twins like it does on the 2nd gens. It seems that with the increased coolant flow, it dissipates the transmission temps much quicker.
I know this is all subjective information, but I thought I would share what my initial impressions were.
