That's what I thought, Mark built a TT '64 Chevelle a while back, very nice.

yes, this is that car. Well, I found the reason I'm having a problem with the boost levels. The intercooler was not built for this power level, and simply won't support my airflow needs.

I have a 24" wide by 12" tall and 3" thick core with side tanks. So the unit has air flowing horizontally, which is very restrictive with that config of a core. If I could swap to a vertical unit, the same size core would be much more efficient as it'd be 24" wide and only 12" long. Unfortunately that won't fit without a complete re-doing of the front end of the car. According to Bell my intercooler config and size is only real efficient up to 400 hp or so.............

The tech at Bell guessed the exact boost drop of my combo just off the intercooler specs and boost level into the core; I didn't have to tell him. My plan is to bypass the intercooler for now and plumb the turbos directly into the throttle body and run water injection as I have in the past. It may not be ideal but it definitely works and I'm sure the power difference will be huge.

Thanks for all the help, it is much appreciated.

i say you go with the 50-50 meth/h20 for your intercooling needs,
it's a win win... 116 octane for the price of pump gas and no
detonation/pre-ingnition worries,...more timing =more power
(with proper tune).
