BBM worthwhile?

santoitaliano · 12-02-2006, 10:29 PM

hey all...

quite simply... is BBM a worthwhile mod?

what gains may i see on my 3.9 w/ wade 977b?

info anyone?

low down touque, take off qwicker really, its not a bad mod, but keep ur old manifold on if u want a turbo later on

gotta change the ecu over to el too

so that means a complete smartlock conversion is in order? then im guessing comes the insurance hassles? hrmm... sounds like a drainer... need unichip lol

How much is a BBM are they compatible to CFI?

why? i mean why would you keep the old one to change it back over if going forced?
the BBM is a good manifold, and JMM have shown it make 600.8hp so far? dosnet really sound like a limitation to me?

this is a dyno comparision of my car (auto, LPG, wade 1004, extractors and exhaust)
vs XRated's (manual, wade 1004, cat back exhaust)

i doubt my mid range power advantage is the extractors, the BBM deffinately makes it better down low.

unless u wanna stuff around wit the butterflys and the ecu go for it, as iv heard, theres a bit of configuration involved to this as the butterflys for the turbo arnt gettin enought air

anyone knows what im on about please explin properly, im such a newb

like effalcon said too, its all low down, ur gonna get a good take off with it on

stiddy: do you know if JMM are using it with the butterflies in it still?
while its not a restriction, doesn't mean its the best available.

the earlier manifold is more suited to turbo simply due to less i/c piping and rumour has it the ED manifold flows slightly better.
adrian vella's turbo EL is running an earlier manifold and his is the fastest eseries turbo that we've heard of.

How much is a BBM? and would it make a difference in rwkw?

no more power to be had (maybe just a little), but you will get more torque, if you do not do the EL ecu change as well then just forget, I tried the BBM with an EA Ecu and after market runner switching, I LOST power as it went too rich in the top end.

Honesty man, I would really doubt JMM still have the butterflies in it, even goin a hardcore n/a motor my engine builder wants to pull the butterflies out and port the manifold itself... so I would think JMM have done that too..
Im not saying its the best available by any means, but I am saying it would be better over what he has.
I agree that the disadvantage would be the lengthy intercooler piping needed to run it, but that would be evened out by the extra/better flow from the BBM imo..
So far the best inlet manifold was a job done by Nizpro, and they do suit E-series, AU's and Ba's.. but theres the same question, WHY? the bbm or even the stock on earlier models flow really well anyway...

but for n/a id say the BBM is the way to go..

EA2BA · 13-02-2006, 12:29 PM

Pulling the butterflies out on a n/a motor sounds very interesting seeing as when you lock the BBM open, which means as good as no butterflies the engine is lucky to rev past 3,800rpm, so I would be interested to see what cam would over come this problem.

santoitaliano · 13-02-2006, 09:30 PM

umm... i highly doubt ill be going turbo in the next few years.. how hard is it to change to el ecu?

is it way too much buggerin around?

you've got it the wrong way around.
if locked on long runners, (butterflies closed) it doesn't like to rev beyond 4000rpm.
if its locked on short runners, the car revs fine, just acts like an ED manifold.
