Went for a quick jaunt this morning with a friend manning the laptop from the passenger seat and got some good logs (scary logs too). I'm still sifting through it but suffice to say 65F ambient, 130F-170F under moderate (10-15 psi) 180F-200F under heavy boost (15-24psi). I see a water/air intercooler in my very near future. The good news is that even at 24psi/6.5k rpm injector duty cycle was around 84% so I think the 750cc were perfectly sized. I'm really impressed that the water injection keeps detonation at bay and cools the heads effectively with intake temps like these.

Got a little work in this weekend even though I intended to relax. Funny how that works out. I pulled the bumper out of storage to see how it would fit, then made a few measurements and next this you know I've got a cutting disc on the grinder... Then this happened









This is a very preliminary setup but I think it gets the point across. I went with the ronal spoiler because I has a flat bottom and a good clean profile. I feel bad for cutting it up but I hadn't seen anything else that would do. I widened the bumper 10" and the ronal spoiler by 13" to get the perfect fitment. I'll fill in most of the hole in the spoiler leaving an opening for the air/water radiator. Next it will get a splitter/front under tray which will support the air dam and give it a lot more strength. Eventually I want to use this setup to make a master to pull a one piece bumper/air dam from so spares are easy to make.
