yeah im just running the 252 for daily driver duty once some more parts come out for the car im getting a camaro to drive and ill retire the cobalt to race duty. im probably going to use the S259 with a billet wheel thats the biggest turbo in the S200 line on bullseye's website. im only going for about 700 bhp.
figure if im going to drop 20+k (im already in for 14k) on something your going to want more than 550 trust me ive been there but im building mine for highways. racing from a stop in a fwd car is extremely frustrating especially if your use to rwd

Im excited to se these released i want want want but i would want a more aggressive cam then the one they are testing of course. Im planning to port and polish my head and get valve springs..etc
not necessarily a good idea.. remember DI is VERY flow/atomization Dependant.. zzp themselves did some testing and said it was too hit or miss with a ported head if i remember correctly

Yes, I was just talking about that on page 8. The flow gains are there, but tune-ability, drive-ability, and fuel economy are sacrificed. Then it just come back to the fuel system limitations that can come into play on the stock head anyway. Then the ported head gains are reduced, but the down-sides are still there. That's why I went back to the stock head.

I was going to be content, only occasionally coming to see what's said, but then I read this;
wow.
why the name calling?
Matt said that the advertised duration @ .050 would be the same as the duration at @ .006 - which is not only improbable, but impossible.
Please let me build upon this incase any of you are as of yet unaware;
Duration advertised "@ .050" is the duration of the lobe between the two points where the lift is measured at .050" off the base circle.
The difference between .006 & .050 will indicate the lobes ramp...
You can have two cams with the exact same advertised specifications (often @.050 is not used for the advertised), and unless you look at the lobe ramp, as well as things such as and the lobe centerline (in relation to the installed position) you have a drastic variation of camshafts which are being portrayed here as exactly the same.
Yes I realize that ideally you want to degree any cam being installed, but while at it, many opt to change the installed position to suit their own preferences;
Also, if anyone was to install a cam, and not verify that they have installed it correctly, that's their problem.
I only posted in this thread in the hopes of seeing what was had to offer, and ralliartist seemed to understand what I was asking - as well as my frustration at Matt saying he had these cams while not giving any real information on them which I believe to be usable to much of the CSS.net membership.
Why did I post again?
- because CSS in similar fashion came through when I was called a douche bag for asking what seemed to be an otherwise obvious question.
wow guys.
You're all acting like I've been personally offended or something...
From my understanding, when something progresses to the point of being tested then posted/printed about, that means odds are specs are pretty much nailed down.
I mean, I thought that I was clear enough with this reply;
then there's juvenile replies in my direction??
wow.
For the record, you never upset me.
I read what was essentially a teaser thread, and didn't come to the conclusion that you were still going to possibly change the cams - because that would make a teaser thread kind of pointless...
Once I read you say that the grind wasn't nailed down, I let it drop... perhaps some of you missed this in your rush to ridicule?
....
on a completely unrelated note;
Merry Christmas everyone!
--> hopefully none of you are in my position ~ of having yet to start shopping

Please don't take offense by this, but if you don't want to disclose w/o buying, that's one thing - but I for one don't buy anything unless I am informed beforehand.
again, no offense intended - I originally subscribed to this thread in hopes of reading the specs on these cams.

all you had to do was say you're not releasing the info right now.
don't worry I'm unsubscribing from this thread, and will know better in the future than to ask (you) questions.
buuuut, w/e
merry christmas indeed, and yes, i need to get to the mall today too
it's really easy to misinterpret stuff posted online, I am guilty of posting in too strong a manner, as well as misinterpreting people... but name calling is hard to misinterpret.
the mall... hmm... probably should do that some time soon

Of course had you responded to my question about which part of my post didn't make sense to you, I could have pointed out your misunderstanding days ago.
The thing I really don't get is how you keep acting like I am hiding the specs. I stated that they were on the first page and you keep ignoring this fact.
