looking for likes/dislike with this setup.
i've heard that it is similar to 60-1.


any comment are geatly appreciated

 

Jay from the NW Crew ran a big HX35 on an LS/VTEC. He said it spooled in second gear. Watch the february 05 dyno day video, its in there, hatchback.

 

was he on a OEM block??

i am shooting for upper 200's on a stock LS, but i cant find any compressor maps for holsets to see how big they are. only thing i have found is that the turbine housing is 12cm^2 ans the comp is close to a 60-1

 

stock block, think he made 320+ that day.

 

what are the a.r

 

where would i find a re-built kit for one? the one i am looking at has a t3 inlet flange and a garrett 5 bolt outlet

edit: e-gay pwns me, found one for $68

 

well i just bought it, Holset WH1C $83 shipped from e-gay. the guy isnt sure of teh turbine CM^2. but from what i have read most are 12cm^2 which is ~.58 a/r


we'll see what happens when i goes on teh car

here's some pics

 

2.0 LS. Spools at 3200, 10 psi by 4200, made 340 whp @ 12 psi before manifold fell completely apart:




Expect spool at 3500-3700, 10 psi by 4600-4700, once you get moving the boost will stay up where it should.

If you tie manifold runners so that collector is seperate, and one side of the turbine gets cyls 1+4, the other side cyls 2+3, then expect to spool a lot quicker. I'll post pics of my split tang collector when I get off my sweet *** and take them...

 

i think this one should spool a little qucker being as it is a smaller turbine.

the split collector sounds sweet, but i am going to use a Log mani because i am poor.

would pairing 1-2 and 3-4 work too?? like splitting the mani in half with a divider??

 

XX cm^2 to .XX AR conversions are, uhm, a little frux. I wouldn't hold the exact AR as a concrete figure - I've heard everything from .58 to .8x AR values for 12 cm^2 housings. Also, it's sort of like having a .63 AR turbine with a stage 5 turbine wheel, like you find on that Full-Rice ----, the spool is a lot different than a regular .63 AR turbine with a run of the mill stage 3 turbine... the bigger the wheel is, the spool properties change a good bit.

I have a DIY collector I fudged together, used a piece of 1/2" plate as a divider to keep the two sides of the turbine housing seperate. It's really hard to get the tubes routed the way I described without turning the turbo "sideways" like you wanted to feed the inlet with ram air. Right now I'm waiting on $25/per very short radius bends from McMaster to complete mine, because of how I have to route the tubes. If you're dealing with a 92+ era chassis, your job will be much easier in this regard; the older rides have less room between engine + front end, and less available height above the engine before you hit the hood. There is a reason the guy who owns the 2.0 LS in the pictures above ran his charge piping through the frame rail - I'll be using a tall + somewhat narrow "backdoor" IC arraingement for mine.

If you want more on the manifold theory and collector design, I have a nice little writeup on pgmfi.org's theory forum.
