finally came in my 75mm BBK, got it for 121 shipped brand new

 

how much power do those things add (RWHP)?

 

i think 5-8 with an intake and exhaust. was seen when u put a 75mm on a 4.6 and match the plenum. modular depot did a write up on it

 

Doesn't add nothing by itself as a bolt-on to a stock motor..Your motor has to be moded to make use of it..

 

That's sweet Fast - Didn't you polish the TB Elbow as well?

 

what is this i hear about polishing the elbow? I have installed one of these already. What do i need to do to the elbow, how long does it take? and how much should it help? I have exhaust and k&N intake, but didnt notice that much from BBK throttle body.

Thanks in advance

 

and intake manifold.

 

heres my job on the port.. the inlet is ported to 80mm. i didnt see the point in polishing it up and smothin it out being that it would take another 2-3 hours for no gain

 

Polishing the elbow along with a good intake helps with airflow as well, but your motor can't make use of it without the necessary hardware that would call for more airflow.

Mods like a good set of kook's long tube headers and a Magna Flow Cat back system helps there. An Ex-Cal 2 Tuner would make use of the BBK. There has to be a demand for more airflow... Upgraded injectors and a Walboro fuel pump also are pieces of the puzzle..

 

MANNNN, that looks like it was a biaatch to do lol - lots of work. Then what TB were you running before the you got the BBK? Or do you have two elbows??

 

stock ported

 

what did u use for that? how did u do that? how long did it take and what type of gains will u see form doing all that work?

 

HI!... Been there, done that........... 7 years ago!

 

meh i dunno 5 hours. and i used a die grinder with an aluminum bur. then some sanding drums to smooth it up a bit

 

heres another one of those WTF did they angle the TP sensor up???


because they angle it up the connectors hit for the TPS and IAC. so i had to go find one of my spare ones and pray it was angled differently. well i did i had one. and it works so just be ware of anyone if ur IAC connector is on the bottom a BBK wont work for ya. unless u got another IAC
