- - cannot make over 10 psi of boost (https://www.lateral-g.net/forums/showthread.php?t=16503)

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.

or you could mount two water/air intercoolers in each fender in front of the tire! or re-map the EFI and run E85 and full boost, sans IC... mut the water/meth injection is propably the best and quickest fix

I'd go E85 if it was readily available out here, but it's not. There's one place supposed to be opening up this month, but I want to do Power Tour and longer cruises, so unless they get a good network of E85 stations out here I have to stick with pump gas.

Jody,

Sorry kinda off topic but I was wondering what kinda of HP does it have a 12 psi (or current state) and what would you expect at 18 psi? No other reason than curiosty...I am guessing it is BIG POWER

Thanks, it was strictly for my :drool: purposes. :thumbsup:

There, fixed it for you.

that's actually sad but true Troy. It's stupid that 700 hp feels pedestrian................. ;)

Well at least you got to the bottom of it! So there's no way of fitting a proper size IC or two?

sure I can, but it'll require a fair amount of fabbing and some re-pinting of the front inner sheetmetal. Would be a cool winter project I guess, but for now I want to get the boost up and enjoy the car.
