anyone here using them ? some guys have told me to stay away from BBR but none of them have told me why .. Is there something wrong with their CNC ported 3V heads?

 

i was under the impression that these were some of the best out there. well, there cams are some of the best.

they made 416 RWHP with their heads/cams and boltons on a disaster of a tune on stock injectors. i think thats decent, to say the least.

 

stock injectors? uhmmm and I though the stockers 24lbs injectors were good for 400 crank hp.

 

AM4.6 was giving the rear HP amount. Generally 15-17% lower than the crank.

BBR is a great brand, if anyone will lend me the money, I will test out a heads/cams package. I think that dyno car would be a lot better and way more stable with just a few extra things.

 

yeah that makes 416rwhp -->>490 crank hp. Thats the doubtfull part of the stock injectors and fuel pump. anyway ... could´ve been swapped without saying it cuz that makes it more expensive to do in the overall !

 

They dynoed it once and turned it off.

That is pretty much the only reason they got by with such an aggressive tune and stock injectors/pump.
