Default Twin 4.5" Intercooler question

I know this is a very stupid question, but hey where would we be if nobody asked questions?I'm just curious if any one has tried to run the Twin 4.5" Intercoolers on a TT build? I plan to run a FMIC but I am willing to try something new if it will work! I highly doubt it will but like i said before, I am just curious!

Well I think it is possible with a single turbo but I may be wrong. I'm curious about Twin Turbos though? Maybe someone with more knowledge will chip in and help us. I have no problem going with the FMIC, but I'm just curious.

Lots of twin kits utilize 2 separate intercoolers and merge at the throttle body.

So the twin 4.5 intercoolers would be the fine at 700rwhp with a PT6766 turbo hooked to each one? And if i wanted to turn it up to 1000 rwhp it would still be fine?

From What i understand you shouldnt run the ATI twin intercooler setup above 15#'s of boost without meth, but they are plenty good at 15#'s im making 741/748 through them at that boost level... theyre for sale btw lol

Well i do plan to run a water/meth mix kit from snow performance. What engine is your setup on? Mine will be on a 370. If they will work then I might try to go that route instead of the FMIC.

I used the 3.5" ones on my rx7 and my ltd, iats were higher but power was fine. The ltd at ~3700lbs ran 140+ mph with them and my rx7 went 156 if I remember correctly. Going to a 31x12x3 did net some lower iats, but no gain in mph on the ltd.

So the 4.5" ones should be fine even if I pushed them to 1k hp with water/meth injection? I don't think I mentioned this but this is going on my DD. I only plan to stay with 700 rwhp but I just want to make sure everything will be able to stand up to 1k just in case i want more, i just want to be safe the 1st time so I don't have to change anything later down the road.
