>>Hi all,
>>
>>Q regrading S/C 3800.

>>In Aus thay're fitted in Holdens. Drove one on the weekend in a LWB luxo

>linear power delivery.
>>
>>Now, wanted to force induct my own earlier 3800, questions I have is if I

>the MAP would never see boost.
>>
>>My only concern is the MAP may be subject to too much vacuum under hi

>>
>>Would this cause a problem?
>>
>>Any comments suggestions?
>>
>>Anyone Stateside know the price of a factory S/C for a 3800 - a local
