The truth of the matter is that the lower radiator hose blew off, hence the visibility of coolant. I wonder how many peeps have actually heard a motor let go on a dyno. In the past 9 years of personally having witnessed 1000's of dyno pulls for r&d purposes, I've seen and HEARD a few..
Rod knock is pretty audibly obvious and a hole in the block = oil on the dyno (in conjunction with coolant)
and a gnarly metal on metal orchestra IMMEDIATELY following.
The car was thrown back together at the last minute because we were invited by HIN to attend the dyno event. In the haste of everything, the whole rear end was to be put back together, the roll cage was painted, a full stereo system was put in, AP Racing BBK was installed, the GT37r that put the car into 11.00@127 was pulled and the 76s was put back in it's place. We would have left the 37r in the car, but Performance Auto and Sound Magazine is shooting it for their cover today and wanted the turbo that made 906whp to be left in the car. Originally, the tune was made for over 900whp, but once we arrived at HIN and scoped the competition we ran a different, less aggressive tune, as to avoid catastrophic failure on the dyno.
The car put down 706whp, winning the dyno event. Pretty pathetic that 700whp wins a dyno event at HIN Pomona huh?
As stated above, this motor is the original motor that's been in the G from the production line. The only upgrades are pistons, rods, cams, standard APR headstuds, and valve springs. It still retains stock sleeves, stock crank, and the rest of the valve train. This motor is and has always been purpose built for r&d for Intense, ProEFI, and PowerLab. It's best time at the track thus far is 11.00@127, with only 600whp on the 37r.

Well, I'll just say that I'm not here to sell anything. If I were running a Garrett turbo, it would be there in my avatar. I also did the PF website, hence the banner.
But yeah, back on topic.

The lower radiator hose has suction being put upon it since its where the water pump pulls from, so kinda odd that is just blew off....

So, if it senses pressure above normal it will either default to base boost, evoke a limiter, turn on check engine light, or disable nitrous (depending on how the tuner sets it up). In this case the radiator hose wasn't tight enough, because the ProEFI didn't detect the radiator pressure going north of 20psi.

I don't know Jason's (ProEFI) upcoming schedule, but I'm sure there will be a thread

I guess if they werent tight they coulda blown off or if they were old they coulda just popped.

That is a good point. I hope you guys didn't lift the heads, because it such a PITA to replace the gaskets, but this is a very realistic possibility considering all the engine has been threw.
Subscribed for further diagnose of the cause when you guys get a chance.
Good luck,
