BBK Full/E85 vs FP_GREEN/C16.. FACTS!
I know it may get controversial, but facts are facts. Besides, I'm getting even older and sinile and I better get my thoughts down before it's too late. So, here goes.
We've all seen the statements of the BBK Full turbo being compared to various FP
stock type turbos, primarily the FP_Green. Also, in the early statements, the
comparisons were made with comments which would lead you to believe that the BBK
is better for Pump gas than the FP turbos. This started me thinking, "Why would
PUMP make a difference in turbos?" I understand additional HEAT and other factors, but I still haven't read a single statement explaining WHY the BBK is supposed to be a better PUMP GAS turbo.

Simple the HEAT.
I believe that the BBK is more effecient thus keeping HEAT down, resulting in better results on pump gas.
IF you need to know why I can't tell you first hand as I'm sponsored by neither CBRD or FP, but perhaps since you ARE sponsored by FP you can ask them and confirm the following.
From what I understand the FP turbos use a different size shaft than stock. Thicker. Where as the BBK uses the stock sized shaft. Based on this info, it is my speculation that the FP series turbos do not dissapate HEAT as well, since it is left with stock type cooling on a shaft that would then naturally retain more HEAT. This would also seem to make sense with the noted Red failures, as this thicker shaft pushed "just a little harder" in the same frame under more strenous conditions, seem to like to melt.
wowzers Bryan - dyno sheets galore 
look at the stock turbos beating the green.
I am assuming they (stock turbo) had other boltons over the green...
This really just proves that for any meaningful analysis you really need back-to-back, same car, turbo swap dyno runs...

Scorke, I'll await your empirically derived data on ANYTHING. As soon as someone posts data, there's always going to be the other side. It takes someone to step up and make an attempt at presenting the facts, not just sitting back, waiting for someone else to do the work, then complain about how it was presented.
and FWIW his looks good....i see some dynosheets.

You say you understand that HEAT is a factor but that you have not read a statement why the BBK is supposed to be better on pump gas?.....

Heat inside the turbine housing tends to generate energy. Thus, higher turbine housing EGT's would tend to increase power to spin the shaft, or wouldn't it?

Soon as spring comes rolling along there will be more bbk 1/4 times. And they WILL be in the 10's and 11's as we see the greens doing.
the bbk is amazing on delivery power, which leaves room in the making for a street monster. Give it some time people, let the turbo get out there on the dynos more. Were already seeing tremendous numbers from the bbk though

no sh*t jackass, i was saying wait until spring time when people actually want to go back to the track. Dyno's are just numbers man is what i was referring too.
you need to understand what someone is actually saying before responding
124 with just bolt ons. How's that?

Nice post Bryan. You can really tell that it's the middle of the winter and we're all getting cabin fever...it's -21F here today and the only thing to do lately is sit and compare numbers....I've been doing it too!
