#16165, "Some basic turbo tech chat between murix and I"


          

Thought this would be interesting for those who don't know too much about turbos:

---
MUR1X: when did they introduce purple M&M'S??
Mystic511: purple??
MUR1X: yeah
MUR1X: I am eating some now
Mystic511: that's the one that only like me and two other people voted for
MUR1X: there are a lot of purple ones in this bag though
Mystic511: dark or pastel?
MUR1X: dark
Mystic511: maybe they were suppose to be blue, but m&m fucked up?
MUR1X: they have blue ones though
MUR1X: purple yellow purple blue purple brown purple green purple red
MUR1X: blah
---
ok, so that part had nothing to do with turbos, but i thought it was funny.

things have been edited to make sense, and also to cut out the crap talk. =P
-------------------------------------------------

MUR1X: which sounds like aS20G to me
MUR1X: and defeats the point since a S20G will actually accomplish what I want
MUR1X: but I do not want the lag
MUR1X: Bill once spoke to me about a possible BB option - that might be my solution
MUR1X: but the argument I had was that the A/R housing is too large so the turbo does not spool till late in the game
MUR1X: a S20G starts spooling when a S16G does but the larger wheel makes the process itself take longer
MUR1X: going bb would make a S20G very much like a S16G and what I want
MUR1X: but that is assuming it is possible - Bill did mention it once to me
MUR1X: I guess that would be the cheapest ideal route for me to go
MUR1X: I want midrange - lag = peaky
MUR1X: same stupid shit as vtec
MUR1X: area under the curve means a lot more
Mystic511: s20g with BB = good.
Mystic511: that's all i got from that.
Mystic511: heh
MUR1X: yes
MUR1X: hehe
MUR1X: the downfall of the super turbos is their single selling point
MUR1X: the 10cm A/R housing
MUR1X: the A/R house sizing determines when initial spool-up occurs
MUR1X: wheel size determine how long spool up will take
MUR1X: that means bb would cut down on total spool up time but not when it begins to spool
MUR1X: the advantage of larger housing is less backpressure, no boost creep, and more overall flow
MUR1X: a big 16G flows 550 where a S16G flows 575cfm
MUR1X: a 20G flows 650 and a S20G flows 680cfm
Mystic511: awesome
Mystic511: you just cleared up turbo tech for me in 5 mintues
MUR1X: hehe oh
MUR1X: another consideration is that lag is actually good for fwd because a small fast spooling turbo can break the tires
MUR1X: but their is a window between too much and not enough lag
MUR1X: I am determined to stay in it
MUR1X: for a streetable fwd the S16G does quite well actually
MUR1X: long gears help traction too
Mystic511: yea, i think s16g is a really good turbo.. that's why i decided on hrc instead of star
MUR1X: the star turbo is fine but I want to knwo who sized it
MUR1X: it is weird on paper to me
Mystic511: it's stupid.
Mystic511: =P
MUR1X: I want to know if those guys get compressor surge
Mystic511: the BB option was the only thing that made me interested in star
MUR1X: I doubt it
MUR1X: the BB is overhyped
MUR1X: Greg has it
MUR1X: I am asking him when he makes 16psi by
MUR1X: he makes 16psi at 4200rpm
MUR1X: he dynoed 283@15psi
MUR1X: Armond makes 18 at 3800-4000 and dynoed 324fwhp
MUR1X: go figure
Mystic511: heh
