what a/r should i look for in a t/3 im looking to pull hard all the way to the redline.(7k)

Honda16hb

what motor? most people like the .42/.48 for quick spooling and for d-series action. Alot prefer .60/.63 for b-series upper level boost.

chevy

its a d series, thanks for the info

well a/r isnt nearly as crucial as turbine wheel stage. i mean a stage 2 wheel with a .48 a/r is gonna be alot laggier and flow more air then a stage 1 wheel with a .63 a/r for a d16 id go stage 1 wheel with a .63 housing. . or go the other way a larger turbine wheel will have a higher specific pressure ratio with a smaller a/r vs a smaller turbine with a bigger a/r

if your going for a 7k screamer looking at a stage 1 with a .63 might be the best comprise if just a shade laggy. with a bit of spark and fuel didling it might spool up nicely.

I don't know about all these stages and crap, I get my turbos from the junkyard.

Good call Kyle. This is HMT. We don't change wheels or any of that ----.

Honda16hb

the only ---- we do with out turbos is mount em and put new seals in, other than that theys just spinny things.

lol, same here im a newb to all this. i was told a t3
would be a better turbo that would not flatten out.
i was going to go the way of a rhb5 but did some reading and found out that it flattens out 5rpms so its not what i wanted. any other suggestions on what kind of turbo would be best for my applacation im all ears

sean88accord

well the question was specifically about a/r's. i gave the best answer i could. for a d16 figure a stock 42/48 saab turbo would be a shade on the small side at 7000rpm. but given the VE or volumetric effiicency at 7000rpm it should be ok. if you need more boost but i doubt you would the sabb turbo sould be in thoery be upgraded with a larger compressor wheel in the compresso housing to like a 60 or a s60 trim and that would net you around 325hp. but the exhuast side would be a bit stuffy. at that point it would be time to go with a stage 2 turbine and a .48 a/r on the turbine side. but if your goals are modest. 250hp ish then a stock sabb 42/48 or similar turbo will be fine.

dont get all shitty. you asked a question i gave an answer. had your question been what size turbo should i run then i could have given a more specific answer. but in all honesty without a hp target then its hard to say wtf you should use.

we show a comparison of the Higgs factory µ+ µ - collider and an e+ e- collider (NLC) that could also
study the Higgs [5]. Note the very great differences in cross sections, indicating that the e+ e- collider must have very high
luminosity. There is also a possibility to search for CP violation in the Higgs sector as we discussed at a recent UCLA

The Proton Driver is a rapid-cycling (15 Hz), high-intensity (3 ´ 1013 protons per
pulse), 1 MW 16-GeV synchrotron. It serves a number of purposes in the Fermilab
hadron program. In the near term, it replaces the present Booster and increases the proton
beam intensity in the Main Injector by a factor of four, thereby providing an upgrade path
for NuMI and other 120 GeV fixed target programs. It also opens the avenue for new
physics programs based on its stand-alone capabilities as a source of intense proton
beams. The beam power of the Proton Driver is a factor of twenty higher than that of the
present Booster. It can be employed for the production of high-intensity secondary
particle beams of pions, kaons, neutrons and neutrinos. In the long term, the Proton
Driver can serve a neutrino factory and a muon collider by generating intense short muon
bunches from a target. The design also allows an upgrade path to a 4 MW proton source
by adding a 600 MeV linac and a 3 GeV Pre-Booster at some late time (called Phase II).
To meet the requirement of a muon collider, such as a Higgs factory, the number of
bunches in Phase II will be reduced to four.
