Hopefully in the coming spring/summer we'll all have a chance to get the 90q20vt and some of the cars Eckert Motorsports is converting plus customer cars out to some of the bigger shows around East. Hopefully will make it to Nationals next year as well with the 90 and other fun toys!

I didn't have plans to do that, but I will if it isn't too difficult. The upper portion of my 3" downpipe is from the Bufkin car. The rest was fabricated out of 3" mandrel bent steel by Ken Fluhr. Downpipe goes to a Magnaflow cat, then to a flex pipe, then back to the bend towards the side of the car and finally to the resonator, which came from an early version of a Stromung exhaust system for an UrS4. The resonator was deemed too loud for that system, so it was cut-out and replaced with a proper muffler. But, it cuts the noise "just enough" for the eS2 race car.
I'll snap some photos tonight and measure the distance of the tip from the tire. It isn't so much the distance as it is that the tip is pointed towards the tread of the tire (we hadn't extended the tip far enough). It's all fixable with a little effort.
Thanks, Jim.

Basically, the car has been together for awhile, but I haven't been able to drive it because it didn't have an exhaust. I learned a long time ago there is a difference between good attention and bad attention, and I didn't want to draw attention to myself in my small, quiet neighborhood. The noises coming from the garage at all hours of the night probably already have them suspicious of me.
Anyway, we got the exhaust installed a few weeks ago, but I still couldn't really drive the car for administrative reasons (insurance, registration, inspection). Well, I finally got insurance, so I ventured out just beyond my neighborhood and found a short stretch to finally get into the boost. I only did one run and the car behaved fine. I have my adjustible BPV configured to be a BOV temporarily, but the adjustment is different for each configuration. In other words, as a BPV (as it was set), it is set to the lowest spring pressure, but as a BOV, it should be set according to your max boost pressure. The result was that during my run, the BOV let go at 14 psi or so, far below my max boost pressure. Still, that is correct behavior, so everything looks good so far. I expect to have the car registered this week and inspected no later than next week. The car will go to its first track event on 11/13. I'll keep reporting my progress. Maybe I can get James to film a "startup" clip like you and he did.
Later,

I made a pressure tap from an old O2 sensor and some brass fittings. I'm getting 5.5 psi of back pressure right after the turbo at WOT and about 6000 rpms. I thought it's a little high so I started tapping holes in my exhaust. So far I've found that each muffler adds 1psi, and my hollow cat adds .5 psi. Either my DP, or flexjoint are causing 3 psi of back pressure which sucks! More holes are on the way to narrow it down...
