Ok I'm looking to build a street strip monster I'm looking at an hx50 with a 69mm inducer and a 98mm exducer on the compresser side and 78/88 on the exhaust side with a air ratio of .96 I want to know if I would be able too spool it with 5k gsk and 7x18 injectors

 

you will, but you won't be using it as a street truck...

i'd say it was purely track... if you want a fast street/strip truck you build a compound system, run that HX50 under your stock charger...
