It's too bad the "official SOHC supercharger thread" has fallen to pieces. Not sure what happened, but hope you guys can get it all sorted out. Anyway, perhaps to get this thread back on track... a few newb questions. Don't worry, I won't rip you off or anything. 
So in other threads, I've read about using catchcans since the stock PCV can't properly handle the positive pressure in the IM. How are you guys solving this problem? Is it not an issue at low boost levels (5-6 psi)? Or do you ignore the issue all together (and hurt your reliability)?
Another question that has been brought up but not really fully flushed out is how to tune your setup. JR offers their MAP sensor and BTC, which I have heard will do the job and might be smog legal (see below).
And the last question that is interleaved in both of the above, is how to maintain a CA smog legal setup. An aftermarket catchcan will fail smog. A chipped ECU will fail smog. I am guessing most piggybacks would fail smog too. Thoughts?

you don't have to worry about the catchcan/pvc thing because the jrsc design has an stube between the throttle and intake mani.
This stube does not see positive pressure, and is where the pvc connects to.
Smog is tuf, but if you BOUGHT a stock kit, it IS fully smog legal, and comes with a carb sticker.
The key is to have that sticker. I lost that sticker and had to pull my blower to get smogged, still have yet to put it back on(but it's going back on better than before
).
Honestly, a lot of smog places are not overly ****,
they're not gonna check if your ecu is chipped, or if there's a piggyback there.
as long as you pass the sniffer, have the sticker, you'll most likely be ok.
Might want to stick ur egr valve back on just incase they check for it, but thats about it.

Tad you getting your blower ported. I know I will be but now its just a question of where. Endyn is over pricing I do believ and then there is magnusson and steigmeier(sp?) they have done some Merecedes applications with the M45 and said there was very good results. Magnusson though will also do the s tube and manifold. Never asked steigmeier. They are more of a M112 porter for the ford guys but also do all other eaton blowers.

re-read the post.... i even offered up that y8 pulley. quit being a crybaby. you whine about everything dude... talking about vendettas and ****, dude... you stuck me with the paypal fees and whatnot on purpose because you are vindictive.
and yes, this thread is a waste.... has been a waste. because it is funny when you post up tech stuff that you heard someone say, but somewhere in the translation, it gets fucked up in your memory, and you spit it out 100% incorrect. no hands-on experience, you're just internet reading comprehension tuner. i just die when i read your posts.

I thought he was your boy??? What did I tell you in the begining?????? You sure do make more enemies than friends!

This thread has out lived its usefulness.
I had great hopes that other SOHCers would be inspired to go the way of the JRSC.
I hope you guys can work out your problems over time. We as a community need to stick together.

who knows time usually fixes all problems, I think when the dust clears he will see that im just young and new at this all with honestly no bad intentions, we just had a communication breakdown. I had great hopes for this thread to but **** happens. Joe is a great guy with a big heart, knows his **** and was kind enough to help me out in my time of need which proves my point. I will try to pay him back by building my car right from his help and knowledge. Good luck everyone with your setup!!!!
Sorry if I caused drama, I never ment to.

Anyone have any engine pics installed on a D16Y7?? Just kind of curious as to how everything is situated. I have an idea and I would like to have something to look at. Oh and dyno numbers on a Y7 would be cool too!

ya see!
i've been thinking about this for the longest time.
mainly ever since I saw a back to back dyno with a stock kit.
owny dyno'd at 7psi & high compression, VS 10psi and low compression
the 7psi made more power!
ALSO it's SO easy to up compression on these motors,
just mill ur stinkin head! There is so much material there to remove before you alter the shape of the combustion chamber.
Basically milling it is the same as installing flattop pistons, except all u need to do is pull ur head, dismantle it, pay 50-100bux to a machine shop, and put it back on.
9psi + head mill (10.5comp) + i/h/e + b16tb = GOOD power for CHEAP
yes it's true, there is a lot of heat with our un intercooled kits. And paying over a grand for an lht kit on a sohc seems a bit wasteful. But if you're a good tuner it shouldn't be a problem.
The only downside is prolonged useage, heatsoak IS a problem,
like rr/track time, or long nights of street racing. You're going to see a performance drop as time goes on.
i'm guessing w/ an lht, that 11.5 comp setup would see huge gains.
P.S. I threw the b16 tb in there cuz i just picked one up and it matches my stube inner diameter perfectly. only 50bux too. the stock sohc tb's are much smaller and are a big restriction.

I hear ya!!!! I have been reading up on this for the past few days, im a totall noob to all this but after reading and reading its so odd that you put that down hahaha. I was working it all out on a piece of paper lol. I was thinking of later on picking up another a6 head and having it milled then throwing it on with the 8lb pulley having it tuned and seeing how it holds up. Joe showed me how awsome thos b16tb work with the singlecam sc kits, the original tb are so small and kind bottleneck the flow of air. I should be picking one up in the near future. Good stuff man, bet your head milled and lets see those #

yeahhh it's probably feasible,
i've heard of people doing .060,
but I think it was one guy and he didn't have that much mileage on the motor.
usually people say .040 is as far as you want to go to be on the safe side.
but personally.. I bet if you clayed for clearance, you would find out that you can go way past that.
i'm willing to bet a nickel on it!!
here's a dseries.org thread on this topic.

oh also I would definitely get an adj camgear if milling ur head this much.

So how about porting TAD? ever talk to Magnusson or steigmeir. They both seem to think they can get some better flow and lower temps with their porting. Also you wouldnt happen to know where to see those back to back dyno slips would you??
it was on an old jrsc forum that is prettymuch dead now. I'll see if I can find the link.
I talked to one of those guys about porting, but mainly I was asking for tips so I could do it myself, they basically scoffed at me and were of no help whatsoever.
i'm sure their porting is great, but expletive that ****, i'm a doityerselfer
