i am planning on putting an ihi rhb5 of a t-bird on my d15b vtec. my question is with my crx si tranny will i be cruising in vacuum on the freeway at around 3500 to 3750 rpms or will i be in low boost all the time. thanks for the info

 

you'll probably cruise at +1lbs or so. until you open the throttle that is

 

If you have very light throttle, you will stay in vacuum for sure.. I can be at 5,000 rpm's and stay in vacuum and maintain speed on flat ground..

 

even with that small of a turbo

 

i had a small *** turbo on my LS motor... 5k rpm crusin at 10 vac.

 

it really depends on how much you step on the gas pedal. you can be at 4000 with your foot barely on the gas just cruising you willl be in vac. but while going uphill its hard not to be in boost

 

It goes by load not RPM. I learned that and learned how to drive out of boost. Once you drive it you'll see.
