OK so im gettin my check from school for left over scholar ship money (GO MEAP and cheap classes!!) and i was readin up on some A/R ratios and from what i gather with a bigger A/R ratio on the turbine side your turbo would spool faster right? just like tranny gears the closer they are to 1 the fast it spins right? if im wrong stop me and any point and laugh in my face... but anywho i gotta 2.4 that im buildin for say 15 psi-ish but when im runnin 8 down the block im not tryin to have massive lag (just like everyone else).
But im lookin at a T3/To4E with a 57 trim compressor side and .63 A/R on the turbone side. sounds good to me sincei havent found any closer ratio that i can afford lol.. n e who all info is all was appreciated.

You got this wierd flappin thing goin on with your lips, ya might wanna get that checked out.....
So that means a 60 trim compressor would spool even faster with that same A/R then right?
Thx dan

No, as you up the trim, the wheel gets harder to spin before it starts making boost, so you can't take a .40 A/R ratio turbo, put a 90 trim wheel on it and expect it to provide boost by 1500 RPM's.
I would suggest taking a look at the link I provided in the top FAQ about how to read turbo maps. Its like my 2nd or 3rd post in that thread. It will help you out a lot.

That turbo you listed is the exact one I used. Took me to a 13.8 at 7psi with a slipping clutch, boost leaks from crappy redneck welding, and randomly guessing the settings on my MF2. I thought it was perfect: Spool up was just right, and the topend was crazy.
O noes!
thats also the same turbo I've pick out too. turbocalculator.com has them for $449.
Smokey about what rpm does it start spooling and what rpm does it reach at full boost??

Fire bug- yea i saw that and was thinkin aboot it but that one isnt a garret or anything its an off brangd turbo isnt it? has anyone else run that? is it quality or junk? i do like the idea of a 6 month warrenty tho.

yeah right after I posted that I went back and read it a little closer and saw that it wasn't a garrett so I found one a cheapturbos.com for $589 brand new with a 30 day factory warrenty and a Tial 38mm wastegate for $239. I will most likely be ordering from them because I don't think i trust a no name brand of turbo.

Sweet deal i think on turbocalculator.com it comes out to 599 with shipping. so i might run that unless that price u just posted includes shipping too. and thats the same wastegate i was thinking aboot gettin. sounds like a dec. price too. good lookin out on that.
Thx Dan
