    Opinions from this group, will 2.5” from the headers back be ok or is it a definite that I upgrade to 3” on out? What you guys do? I know I could search and find a lot of opinions but I’d like to hear from this small group

    2 1/2” is fine.

    After all, S.W. Sells the header and leads that bolt up to the tiny H pipe and that combo works fine.

    Cool. We plan on replacing from the header the h pipe with an x and 2 1/2” to the mufflers. I still have stock mufflers which I read flow pretty good. I actually like the Mello sound, but if they restrict flow I’ll replace

    . What pulley are you running? I think I’m going with the 3.60 anyway.

    Not telling ya how to do your build but, a 3 bolt timing cover and an 8 rib swap should have been on the table.

    PLEASE tell me that's not how you plan to run your pcv setup. How did your old engine blow?

    I shift at 6,000 and it’s already at 26#s. Street tune I let a 50MM TIAL with a 5# spring act as a wastegate to dump the excess boost to a more 93 pump friendly 20#’s.

    I have no clue what she could produce at 7,000+?

    But no belt slip!

    That’s how I’ve been running it. Ran it this way for at least 3-4 years. The engine hit the rev limiter and leaned out on cyl 3 I’m assuming and broke the ring land. That’s why I’m here for pointers. It was recommended years ago to get a oil separator so I did. What do you suggest. I’m here for it

    Something along these lines.....

    .
    You "feel" the difference because you want to "feel" the difference. Since you just spent money on the upgrade you "have" to feel the difference

    I'm looking to eliminate the double pump process I have to follow right now to get the pedal hard

    On a centri and turbo setup pcv is forgotten by most. From idle to 3000rpm the car is N/A and vacuum is present . Above 3000 your making boost through the intake and with a stock Marauder pcv valve (which isn't intended for boost) it will allow the boost pressure to enter the PS cam cover.

    The post Blazed71 put up is good but I would make a few changes to it as newer and better parts are now available.

    1) no need to gut the OEM pcv or swap the inlet for the pcv location to the DS cam cover. (03 cobras have a push in pcv valve)
    )2 Get a pcv valve for a 2008-2010 GT500 it will screw into the stock location no problem with one exception. Its too tall. So cut it down to length with a hack saw
    3)add a one way check valve at the stock location on the intake (yes you can keep your catch can if that's what you want to call it )

    This setup will yield a cleaner look and will out perform Embassy's old setup. If you want to get fancy you could get a wiring pig tail and wire the heater element for fun. The Gt500 pcv has one built in

    I have no doubts you were sending boost into the engine as you have presented it.

    Research the 8 rib swap, and if a 3 bolt cover isn't in your future at least get a single bolt thumprr tensioner.. They're expensive but well worth it!!

    Sorry for the interruptions...… Please carry on……..
