how much of a difference in flow in there from a stage 3 or 5 .48 housing versus a .63 standard exhaust housing.


what are the stages and how do they affect the turbos performance???

 

did you try both of these by any chance???

and which .48 is it, standard, stage??

thank you BTW

 

is there any given power numbers that can be made on AR exhaust housings????

i mean will a .63 support XXX.xx HP???????

 

My .48 spooled 200 rpm earlier but the .63 made a bit more power from mid range all the way to the top. I think the .63 is better for higher boost cause it flows more.

 

was that on a B series or a D series?

what power levels were you achieving with either?

It is a typical stage 3.

Yes I have. I ran it on my stock bore B18B with 8.8:1 compression and a stage 3 57 trim T04B.

The .48 starts to make possitive pressure right around 2k RPMs and hits full boost (1 bar) by 3 to 3.5k.

I don't have any numbers for you as far as power is conserned, but the .48 does start to die out from 7-8k. It also powered my car (.90bar at the time) to a 13.5 @ 110.8 mph with a 2.327 60ft.

Hope all that helps a little. </TD></TR></TABLE>


VTEC head?

Also, how would you compare this turbine (in size, and flow) to a td05?

 

thanks guys!

i have the .63 AR hot side on my turbo B16 now, but it has a very aggressive compressor wheel that i dont like, right now i get almost full boost at 5000-5100 rpms, i want something a little better spooling

also this is in a "B" housing, i think an "E" with a 60 trim would do the trick tho

Jeremy's motor is all LS (non vtec head)

so what about the stage 5 .48 is it worth a damn??

im just looking for something thats not gonna take 15 minutes to spool a turbo, i should probably save and buy a BB turbo!!!

 

i have the .63 housing on my turbo at the moment. Currently i am runninh 10psi. it goes to like 1psi at about 3500 then just jumps to 9psi at about 5000. note however this is a d15b. Would it make more sense for me to try and get a turbonetics .48 housing to build power faster? I am going to be running about 15-17 psi daily as soon as i hit the Dyno. (note: the block is built)

 

thats pretty much my question too!

i know that all my frineds with built D series run the .48 just in different stages, and i understand that the larger the AR is for higher revving and engines that have more exhaust flow, and pressure.

im just wondering if a B16 which is still 81mm could use a .48 but in a different stage like a 3 or a 5.


i would switch to a .48 on a sohc

to be honest i dont mind building power a bit later because when it actually comes in the car feels very good. the other day i was on the road with a friend we both pulled up at the light together. He drives an evo 3 RS. he did have the launch but when the boost kicked in with my car the race was locked. i am guessing the smaller back housing would move the power band more into the rpm range which would make more sense... i am not the expert so someone else can share their info...
