I think I'll get an infraction if I post what I'm thinking...

Any insight into how the computer actually does all that or is it still "hush hush" stuff at this point.

Two more things.... and

Kilopascals? Bruce is getting fancy...

33 PSI = 227.52699067455592 kpa.

How many decimal points you going out to? LOL

I gotta say.. 227.52699067455592 kpa boost does sound MUCH more impressive...

Ha, ha. No, seriously, the master ECU we have utilizes kpa for all pressure readings for accuracy...

Actually, the car is pretty close to being done. There are always 1,000 little items to close on, but in general it is pretty close. Waiting on the diff to be shipped. There was a small delay in heat treating and powder coating but once we get that then we can modify the upper rear components and measure for the driveshaft.

The center console gauges should be done soon too. They will look just like the factory 4 pack, but have custom Boost, A/F, Fuel Pressure and Tranny Temp guts in there... The computers log all data so we can play back all of the sensors and see what the car was doing during any given run.

After that it is just finish installing the hood, grille and front splitter, splash on a little "special" paint and good to go.

Haven't heard any explosions in the dyno room, so that is a good thing.
