    Re: Pipes pinto :)

    after matching the inlet manifold to the head i got a bit of a surprise



    the jenvey manifold is really nice and seals with o rings, BUT doesnt suit a head with big ports, opening the manifold up to match the head has broken into the o ring grooves.



    fortunatly theres just enough thickness to the mounting flange to machine the grove out.




    at this point i am undecided which way to go, i could machine up a plate like a sidedraft carb has with a o ring groove in each side to carry new o rings, or simply open a gasket out a bit and use a gasket and sealant. theres not a lot of material left to seal with, but there shoudl be enough, at least on injection if it develops an air leak the worst that will happen is a bad idle, no danger of a lean mixture like it woudl get on carbs

    Re: Pipes pinto :)

    at the moment im defiantly errring on the side of using a gasket rather than faffing around making misabs.

    with that in mind i ran a fly cutter across the manifold face of the head to give a better surface to seal against, just for good measure i did the exhaust face too. nothing earth shattering, but a nice touch. its not something i usually have done, but thats simply a case of economics, when i had to subcontact it out it was hard to justify the cost

    Shame about the manifold breaking out like that.

    I like the Milling machine, it certainly looks good.

    Those inlet ports look Huuuuge !!!!

    they are, but thats mainly down to me lifting the ports up, i refuse to use port filler, because sooner or later it does come out

    Did that start off as an injection head then, or a carbed head?

    Dont suppose it makes any difference if you're going to do that to it does it...

    too big! they are only that size because i have lifted them up and the original inlet manifold had big ports!

    in all honesty i dont know ive never measured them as such, and right now the head is 100miles away

    What's the basic advantage of using the 1600 head then Graham, is it the smaller combustion chamber?

    Does a it give a more concentrated burn or something, I don't know I'm just guessing

    Can you still get the same large size valves in it then? I know you you're going offsetting for larger than normal big valves.

    means you dont have to skim the head to death to get compression, but also theres more material in the short turn. before the injection head came along all the really quick pintos had 1600 heads

    I'm trying to run a new Emerald K6. I did have some problems with it at the end of last year and so far I haven't had the time (more like I haven't got off my fat backside) to look at it!

    How do you go about matching the inlet manifold to the head Graham? I don't know if you remember but I got one of the HT straight inlet manifolds for mine.

    spending money is no problem

    if you order the K6 through me at work, i will give you more discount than emerald will im pretty sure you wont pay vat.

    matching manifolds is done a couple of ways on Andys new one i literally bolted the manifold and head together and because the manifold was smaller and soft alloy my die grinder opened it up to match the head without making the head port bigger. normally you just match them to the gasket, so thats what i would probably do open teh head up to match an inlet gasket, you didnt have the HT manifold when yours was built so its not matched to that anyway

    Re: Pipes pinto :)






    had a bit of a play today, trial assembly of the head shows ive gained some more inlet lift, not a lot, but an extra 10 thou is worth having, especially remembering there will be slightly more lift right through the range.
    i was a bit concerned that moving the valve over may give issues with the follower wiping off teh edge of teh valve stem/ follower, but thats clearly not the case, well at least not with the newman followers im using. if i were starting agin with a fresh head i would defiantly move the valve over a bit further

    What about machining the o-ring groves into the head instead of the manifold, looks like you have more room to play with there?

    yes i have thought about doing that. a rienze inlet gasket will just about seal also, another possibility is just to use sealant. as its injected if it did develop an air leak it wont overly effect it unlike carbs

    As above, it is a straight cut dog box and you have to be brutal with it. also a pain in the arse having to go all the way down to get neutral. thats why i wouldn't have one in a road car.
    for a track car you cant beat it and its a joy to use especially when linked up to a closed loop flat shift system

    I thought that would be the reason and as explained above, I was already running an older version which I believe to be even worse than the newer versions

    And funny enough, I have a closed loop flat shift system all ready for it

    Re: Pipes pinto :)

    that manifold is known to add a bunch of midrange torque so we could be looking at 190+ lbft, as for power well i dont like guessing games. I have a figure in my head of whats possible given what it used to make and what improvements its had, but thats where its staying in my head, but its safe to say should go north of 220bhp. but already encouraged by flowbench results id like to start on a new head for it, just got no time, i started work 8 am yesterday and didnt leave until 10.30 pm

    yes, pintos like long inlets, but theres not room to get that manifold in an escort, so ive gone a different way, as straight as possible on the flow bench its worth a few cfm so SHOULD add a few BHP

    So you said Pinto like long inlets as in straight inlets straight to the back of the valve .... so you would not gain anything by running the up swept
    long trumpets Jenvey do ...

    i wouldnt of thought so two reasons, your introducing a bend into the intake and secondly the shape of the jenvey trumpets is wrong! that might sound like a bold claim but back to back testing has shown the big wide radiused trumpets make less power than straight tubes with a simple 45 degree flare, which is probably why weber has been making them that shape for a gazillion years
