Turbo to small ???
 

I have a question, I am running a b18b with 10.5:1 compression and i have a teo4h wich flows 350cfm.
I am pushing 8psi. And i dont know if it is starving my motor for air at 6500rpms. Does anyone know what my engine requires for cfm's. Or any comments???

at 6000 rpm you motor needs 200 CFM.

at 8 psig its 260 (at pressure ratio of 1.55) now go lookit your turbo map and plot that.

260 cfm | PR of 1.55

itll work fine.

sorry, but his name is 'tiny turbo' and he's asking if his turbo is too small, this seems comical to me, ok carry on ;D

lol

yea it is small, a few guys at the race track have named it tiny turbo. The teo4h flows 350cfm at 15psi. So i should be good right?

Re:Turbo to small ???
 

i guess having a tiny turbo is better then having a tiny dick like you buddy :o

:-\ just wonder what type of fuel management you have a timing control?
10.5 an you want a bigger turbo? Heard of many motors poping with out adequate tune.Think of the turbo as a govenor till you get fuel an air an timing adjustable.

i have the greddy emanage fuel controller with the lap top sofware. And i am using a aem wideband o2 to tune it so i belive the fuel is good

its going to spool really fast and be really torquey. The Ls's peak out (hp and tq) very early. I've never been in a ls that had good pull past 6500.
