Anyone know of deffo, 100%, limits on certain items?
Or even how on earth to work out if there is a way without just trying?
Maybe a thread with a list might be a good idea...

Is there a certain limit on power thru a certain bore pipework?
Does boost pressure have an effect, or purely flow/backpressure?

What about dumpvalves, say the usual on most people use, the "GrpA" one, when does that stop being innefective that dumping enough air to not cause turbo stall severe enough to fuck a turbo?

Im using 75mm pipework from turbo to throttle (75mm too) and i dunno what exactly power thats good for, just pretty sure itl be enough, lol.

Same with dump valve n and cone filter, didnt think one will do so i got 2 of each Cossie "GrpA" jobs.

Anyone know any facts for certain parts, scientific or just tested on a car?

A big PF list im sure would be dead helpful to people...

 

7 views, well i thought this would be a fucking good thread

 

Is this post crap or doesnt anyone know?

Thought itd be a fucking helpful post to most people if anyone knew

 

I don't think you'd be able to get a formula as such as there are probably too many variables.
But i'm guessing if there is any such formula it'll be based around Flow rate & heat.

 

dont have much experience to comment on this but i been out in a 3dr running 28 psi and that dumps and chatters!

There you can find the formulas for:
Engine Air flow
Temp rise
Pressure ratio
Compressor inlet flow
adiabatic efficiency
Density ratio (for turbo outlet flow)

Then I guess you'd be able to work out pretty much anything (and maybe become a brain surgeon whilst your at it )
