from what I have heard, the MSA twice pipes seems to accent the semi-high pitched, "brap" noise that the engine makes, which is why I chose it. The single pipe, "turbo" muffler exhaust system that MSA sells has a throatier quality to it thats sounds richer but less refined IMHO, than a Z ought to sound.. but its a matter of what you want not my humble opinion. Just to sum up my longish post above, the MSA twice pipes should have no performance detriment whatsoever.

it will probably be fired up before I get one made, so patience is not a problem here

oh yes oh yes oh yes!!! Thanks for the update, I was just hunting around on google last night for pictures of an SU manifold..... I cannot WAIT to hear how this sounds on an engine, I almost want to start building these for sale because I have the parts a plenty...
Pete, you already know how enthusiastic about this idea *I* am... thanks again for the update
the piece looks FANTASTIC, just what I had imagined. Anything not straightforward about doing the whole thing? Plans slowly come together regarding my own version of this manifold; I still cant get enough hours to make ends meet so "projects" have to wait indefinitely until "bills" are caught up

I think cars look faster when they are really beat up and old looking..
Man, MY car must be one of the fastest LOOKING Z's on HybridZ... click the link in my sig for a post with some pics, I won't disgrace the drawing thread with photos of a car in poor shape.

It isn't just you

I just... I just cant think of anything else to SAY about that!

are we talking about the sharp angularity in the picture of the second car, that distorts the reflection, running along the line of the door handle... or the line that runs just above the gas filler door?? I can't really tell that either "line" is diffused in the first picture. I THOUGHT we were talking the door handle line, but "that line is a major part of a Z" only really fits the "rump" shape line going above the gas door... ????

awesome link, thanks for the post!!
This guy seems rather intelligent. I love it when people defy the impression they broadcast like that.
Cheeseball factor FTW!

check the fuel supply line for clogs with compressed air?
what was "almost enough" fuel pressure? have you tried running some seafoam or injector cleaner in the fuel?
-
just.. NO!!!!
Star Trek or Star Wars?

I am going to point a couple of things out here...
"twice pipes" is a term that typically indicates half of the cylinders using one exhaust pipe, and half using the other. This type of setup is not optimal for engine performance, as it eliminates (or severely hinders) the scavenging effect that one exhaust pulse has in pulling the next pulse out of the cylinder.
If I am not mistaken, Katman, the system you used in your ITS car was a legitimate "twice pipes" setup just as described. If I am not mistaken, Mario's twice pipes setup is ALSO such a design. Madkaw, on the other hand, has a different "twice pipes" setup; as you can see in his first image there is an "x-pipe" where the entire system merges into one collector pipe, thus in effect "marrying" the two sets of three cylinders, and obtaining the desirded scavenging effect.
I own an uninstalled MSA twice pipes system. They come as a complete exhaust set, ready to be mounted to a header. The "eshaust system" you buy begins with one common pipe, that gets immediately split into two pipes running back under your car. In other words, the MSA "twice pipes" setup is NOT a twice pipes setup in the strictest sense (at least, how I understand the definition) AND, it DOES have the scavenging effect that katman's setup (unless I am mistaken in my memory) was lacking.
To the best of my knowledge, this lack of scavenging is the only performance issue inherent in a "twice pipes" setup, and the MSA system *should* bypass that issue.

if this was a gag post, it was very close... but you should have spelled it "timming"

Hugh:
Thanks for the pic post!!! that much more knowledge and confidence to go at it myself, when the time comes.

I, too, have the same wheels on MY car.. and I hate em. Well, hate is a strong word, but my honest opinion is that they are one of the least attractive looking sets of wheels I have ever seen on a Z.
They just seem to say "American Car" to me for some reason. I prefer the standard five slot mag.. which I know, makes no rational sense.. Slot mag, my favorite, A/R "spoke" mag, my least... whatever. No excuses given, I just don't like my wheels.

Don't be so uptight! We're just arguing. Nothing wrong with that. I'm not taking it personally on my end, I hope nobody else is either.
Not uptight.. just, a thread about a 10.3:1 compression motor with an aftermarket cam is a bad place to be the one sticking up for stock EFI on principle
Good to feel comfortable going "toe to toe" with you guys on a subject that, six months ago, would have been totally over my head though.. My brain hasn't been firing this well since my one year in college, and I LOVE IT!!!

if I can take that as a semi-standing invitation, great. Despite all my recent posting, I am in "lurk" status regarding actual working on cars right now.. no dough to go to the show, yanno?
Thanks immensely for the hospitality; and eventually at least a gab session is imminent. I am in the midst of trying to refinance my house right now, so I have domestic issues taking up any productive time.. I use the internet like alot of people use television. Thats what time I spend here; the rest is either at work or working around the house, getting odd projects crossed off the list and cleaning.
Someday soon, though, this will all be done and my stress levels will plummet. Maybe August, september -ish I get to start the grinding and whatnot on the Datsun, but in the meantime it is bare minimum to keep the junker DD running.

I suppose I left out a few details about my engine. I have 10.3:1 static CR and I have been driving around with that for a while. I had to retard the timing *slightly* to make sure I didn't blow head gaskets under heavy acceleration. Now that the cam is in the engine runs WAY better than it did on 10.3:1 and the stock computer, in the top end.
Oh yeah Z-YA... i have the little coolant fuel trimmer
Given this information, I am REALLY REALLY regretting opening this can of worms in this thread, heh
TonyD reiterated my point best, it has to be suited for what it is in. IF it is suited, all I wanted to say is, it works perfectly fine. obviously in this guy's case standalone EFI is more than warranted. -
I will make clear two things: one, I had NO IDEA why he wasn't here as well as "the other place" and two, that I feel his name alone carries undeniable clout; I have seen one or two MEAN z setups on dual SUs and those are the ones that really got the heart pounding, because there was an echo in the exhaust note only produced with the twin carb setup; a hi-po motor based on the same induction as the original 240Z has a specialized tone to it that is STILL very stockish and that appeals to me more than anything else about Zcars. Thats why I want dual TBS for FI.

You know, its one thing to do whatever you want to do to your car.. but sometimes you might sell it and find out exactly how brutally "out there" your tastes really are. Sometimes this can be a painful lesson... not that it will deter any of us, just pointing out a little humor in the situation.

someone gave them to me
I am just reciprocating. -
It won't guys. Actually, had I not published the "other" article here, I'd have been able to use it. I'll have a hardcopy with me at the GRM track event on the 27th where Mayolives will be competing for those who'd like to take a look... I'll also have copy available to read this weekend at the Mid Atlantic Shindig...
If I post it here, it would defeat its purposes for the magazine... That said, I assure you all that you'll be very happy with the production of the article, the pics and data.

Since I had asked the question more than once (I think at least twice in the past) I DO want to clarify that I had anticipated your answer and understand fully. I hope I don't look like an ingrate for even asking, I was simply curious.
Thank you for the courteous answer to a question that may have seemed a little short on tact.

If Ross is watching, is it possible to make a bigger axle with say a 30 spline with a custom companion flange?I think the problem there is the wheel bearing. You need a larger hole in the strut for a larger bearing.
Thank you both, I had both of these thoughts last night when I read the last couple of posts in this thread. Now I know I was right about on track.
O well, 300whp is more than I will ever drop into a clutch all at once anyhow, I am not a big burnout fan.

Grump: are these potential "welders for sale" already spoken for???
Because I am one of a family of young (with two old) hotrodders in need of a welder at the right price.. between my brothers, our father and uncle, we have 5 complete Zs, three of which are road cars, one ITS racecar, and one automatic 240 that we really need to sh!t or get off the pot over (its sitting, in other words, with no plans for it)
Then there's my uncle's roadsters. two street cars, one 67 1600 and one 69 2000, one 2000 Historic racecar, and one of the two BRE roadster racecars. My uncle HAD a welder but its an old Cebora MIG and it needs a couple of parts that are discontinued.
I need frame rails and a couple of quarter panels, and there's just all SORTS of projects that have us keeping our eyes peeled for the right welder.
When it comes to the George Washingtons, I am not the brother to talk to (I am currently struggling to get my managers to put me on more than three 5 hour shifts per week
) but fortunately my brothers are doing much better than I. I just had to ask if these toys were already earmarked for someone in particular, since you are local to me If they ARE "spoken for" I totally understand.
the piece looks FANTASTIC, just what I had imagined. Anything not straightforward about doing the whole thing?

SU EFI Manifold Update
in Nissan L6 Forum
Posted
For MY setup, (when/if) I was anticipating talking my uncle out of an airbox he had made for one of his roadster racecars that would essentially let me pipe an air filter in the stock location to feed the box on the TBs, but I have to check spacing and clearance.. the box in question has a base plate that attaches to the crabs just like a stock 240Z SU airbox, so I may be able to simple fabricate a base plate to fit on my two TBs that bolts to the box he already has.
Helmholtz effect, what?
