I will be happy to discuss the volumetric efficiency of turbos but I do not think this thread requires it. I was assuming since this is a stock motor that the gentleman in question was not going to be using a huge turbo.

 

cfm vs psi is what you are talking about right?

 

i could just run a smaller compressor turbine so it doesn't spool up as fast right?

 

Exactly, but you cant just assume that they are going to be running something like agreddy kit. Do you know how many "budget minded" set-up there are out there running large turbo's? Maybe it's just the latest craze or something but there are several (that I know of) sohc's running larger t3t4's 50 trims even 57 trims with .48 a/r's or even .63 a/r's some even larger and yes they are tuned properly and street cars. Stock engines making 230 - 240whp on 10psi. it's insane. Tell someone like that to run 12-14psi their motor will be toast. 230whp is already pusing it for a stock single cam.

 

That is very true, this thread doesn't require it. I do appologize for coming across the way I did, but thats how it came out. I guess i'm just tired of people saying "oh your safe if you run less then 8psi or 10psi os pushing it" stuff like that is way off mark esp when the person knows NOTHING about that given set-up. Sure 8psi is pushing it on any motor thats running a fmu w/stock injectors and a 12:1 ratio, but 8psi is just getting started for that same motor with proper tuning such as hondata. tuning plays a big role in how much the motor can take.

 

huh....now that i think of it im going to stay NA for now..... there is a lot of tech involved and i need to do more research plus my engine is brand new and i don't want to mess with it just yet thanks for the info though.
