i went for a drive in Secrt the GTR that UAS has for sale for $55,000 and it does not come onto boost properly untill 6500rpm
that has a huge turbo on it. and i THINK its a t88. can you imagine 2 ??? add another 2000 rpm ???
unless your engine is built to rev to 13,000rpm why would you put 2 of them on?
*shrug*
