GT55 Turbo & Cooling Issues!
I have been piecing my turbo kit together over the past couple of years. Finally got it out for a drive down the highway and back to my shop. The coolant temps slowly went up to around 220 and climbing by the time I pulled into my driveway (10 minute drive). I can start the car up and it idles up to about 180 with the fans and does not move until I start driving it. Details on setup below:
GT55 Turbo
CR5 Blocked 430Ci
LS6 Ported heads
dual row cross flow radiator w/16" fan shroud 22.50 x 19 core
stock water pump
E85
no thermostat
I have not trimmed the front bumper yet but will if need be. The radiator and 6" thick intercooler are sandwiched together and I think that is the problem. Should I space the intercooler away from the radiator say 6 inches or so? Will the stock water pump be OK? Here are some pictures below, just looking for some suggestions.

Thanks for all the replies guys! I have come across a pretty good solution, found one of these at the local speed shop.It has a built in thermostat circuit with it also.
I will gain enough room with the remote water pump block adapters for a turbo blanket that will keep under hood temps down even more:
Going to try to incorporate the front bumper support I made a few years back to space the intercooler. Hopefully this should solve my cooling issues:
I am open to any comments and suggestions, posting up as many pics I a can for reference. Thanks!

Radiator Welded Up
Welded up the water pump flange and -16an fittings to the new griffen radiator tonight! Getting closer, now just need to space the intercooler a little. This radiator is the same core size just uses 1 1/4 tubes and now I have two 10inch fans instead of one big one.

the truth is that due to that you cannot move the water too fast
but the is a reason that few ppl that remove there thermostats on a ls1 tend to run hot, that is because there is a crossover between the inlet and outlet of the waterpump that set directly behind the t-stat and the t-stat has a valve built in to cover it
so if you have removed your t-stat you need to get a freeze plug and plug the crossover hole
but i must repeat you absolutely cannot have "too much water flow"

I like the idea of running a thermostat too, even just a 160F.
If you look one some of the big dog cars, they are running radiator caps that high-mounted, I talked to Mike Brown about this five years ago but honestly I don't remember what he said. I'm assuming it works better maybe gets all the air out?

ok Mr. math formula! i think we are talking about two different things. however good luck with your formula.
I use that same pump! with the Moroso remote thermostat, seems to be working for me.

where does the hose on the coolant crossover tubes go? I don't see a spot for it on your radiator. My hose got clogged once and had overheating issues on the racecar...
