Road Course tunes, BBK vs FP BLACK
So I did a "road course" tune for one of my clients with a BBK. Then bout two weeks later, I did a "road course" tune on my car. I figured Id share it because people are always interested in spool and power differences between these stock frame turbos.
BBK EVO
BBK Full
Kelford 272s
CBRD 3.8 garret IC
FP Mani/WORKS o2 housing/WORKS downpipe
SD
FP BLACK EVO
JB FP BLACK
GSC S2s
ETS 3.8 garret IC
BR ported mani/WORKS o2 housing/WORKS downpipe
MAF
Both turbos were tuned at 25-26psi tapering to 24ish.
Both were on 91oct.
There was a difference in temp. The temps during BBK was about 80* and for the BLACK, it was about 60*.
Heres the boost n AFR.

I am shocked to see such a similar shape with very minimal loss in spool between the two. It appears the two also are outfitted similarly in terms of bolt ons cams etc. Are both cars stock bottom ends and if not any bump in compression? I'm guessing not as you probably would have noted that. Also are these pulls on corn or your Cali ****?
I love my BBK Full and have no plans to switch it out but I am just shocked as to how close they appear to spool. Thanks for the comparison!

ill get some charts up-
but- the comparisons have been posted over and over- a 60+ lbs min turbo isnt spooling like a 48lbs min- JB/BB whatever-
both in comparable housings we see the same thing in the evo X stock housing stuff-
by that rationale all greens and reds should outspool the bbk- and that has been proven otherwise also

More so, this post is to show that lag is over rated. Even between the green and the black, I usually only see a 200-400rpm difference in spool, which in my opinion is nothing, for the top end gained. Thats the point of these charts.
