both t4 flange .how much power difference yall think between s475 and precision cea 76/75 on on a cammed 370 ls engine on 15lbs on boost

 

Probably not much at all, be a toss up. Base modal s475 and really not that great, with a billet compressor and the large 92 exhaust wheel it will do good.

 

Base model 475 is great just ask stock48 and kbracing.

The best advantage for the precision is smaller size

 

just asking .some guy was telling me i need to switch to b/w 475.i would have to see a big increase in power for for me to that .. changing down pipe ,getting my tuner jamie to help me retune .

 

the billet 7675precision is a badass unit, they dont advertise the actual power of it but its around 1300-1350

I have two of them

 

Not enough to be worth a swap imo.

 

billet t4 s476 made 1200rwhp on jarrett faggarts nova thru a powerglide and 10 bolt

 

something to think about.....165mph at 3400lbs isn't 1200rwhp

 

so what are you saying? he dyno'd it just for fun. i know dyno is just a number. but that's what he got, and correct, that's his current best on his new setup...which hasn't been too many passes yet. but he's also at 6000'

 

Yeah I remember seeing the dyno sheet last week or so on FB. Just under 1200hp and around 1050ft/lb IIRC.
