Finished some testing at the track last night and no funky problems associated with the afterburner occurred. No explosions or melt downs. I still need to study the datalogs to see if the system helped with anything. As far as time slips, no new bests to report. Performance was not drastically off, though. Performance off by maybe hundredths of a second and 1 or 2 mph.
It's really tough to judge by the timeslips though, because the new system seemed to throw off some of the other timed systems throughout the run. For one, the boost control curve needs better dialing in to prevent some traction loss I was getting on the 1-2 shift on more than a couple of the passes.
During some quick checks of the datalog at the track, it appeared that the boost (turbine speed) in relation to the rpm was better, but it appeared the rpm climb was slower. It's as if a trade off was happening.
Was the afterburner helping increase turbine speed, but increasing backpressure and interfering with pressure pulse tuning?
It's a little early to trash the afterburner idea. There's a lot of dialing in to do with it first. Hit size and the afterburner n/f ratio are two very important variables to play with, now that we're sure I'm not going to blow the downpipe off of the turbine housing or melt down the turbine wheel.
