ElaineZ makes a good point - there are two kinds of people - "Z and Zemi-Z" as she puts it. Or the way I put it, the practical and the romantic. I think http://www.theanimalrescue.com in her sig says it all. An emotional thinker.

Bill, I see your ever popular car gets even more coverage - in the latest Classic Motorsports Magazine! http://www.classicmotorsports.net/ I see JCI got a nice rightup there. The install looks great on your Z!

Sorry to hear about your loss! Do you think the shock to her vanity was too much to handle? Just kidding!

Joe: I understand wanting to keep the magneto - I enjoy the look of REAL nostalgic hotrod hardware, as long as it's the real thing! I've heard Magnetos aren't streetable, but there's probably a way to make them moreso. [sidebar: What torques me off is BS fake stuff: http://www.alsblowers.com/streetinduction.html I can't believe Don has his name on this carp!] If you want to get into the electronics stuff (and all the rest of the stuff with EFI) the EASY way, get on the MegaSquirt forum http://www.msefi.com and start reading. There's alot of stuff in the archives (linked to Yahoo from msefi.com). Probably the best thing to do is read the MegaManual (on the http://www.msefi.com site also). It's not that bad, really. These guys (Bruce Bowling, Al Grippo, Lance, Eric, others) are really all about teaching people EFI and providing OPEN SOURCE hardware and software to do it. The entry fee is below $150 for the ECU kit. Software is freeware and VERY well supported. MegaSquirt is the best way to learn about EFI, IMO. Have fun!

Joe: I've seen true mechanical Hilborn setups (both stack and birdcatchers) on "street" cars, but they are hardly streetable. You're dealing basically with an alpha-N type setup when you go mechanical, and the tuning aspects are not as simple as with alpha-N EFI. I'm sure there are mechanical injection gurus that can make a mechanical setup "work" on the street, but I doubt it's easy, if possible! There are a few places that will take your Kinsler mech. FI setup and convert it, but I think anyone with some talent with a drill press and either a welder for AL or a tap can put bungs in. Someone makes externally pipe threaded injector bungs - that might be an easy way out. Like others have said, come up with a good fuel rail and mounting scheme. Then you need multiple taps/ports per stack below the throttle plates for each of the IAC, MAP, and PCV/BrakeBooster vacuum circuits, as well as small manifolds to run these to. Sizing of the taps/ports is important - too big a port/hose/manifold (volume) and you end with a bit of a plenum for sharing signals from cylinder to cylinder, which is what you're trying to get away from with an IR manifold. Again, drill and either tap, weld, braze, or epoxy tubes into each bore below the throttle plates. Run hoses from the ports to the small manifolds and hook your IAC, MAP, PCV/BrakeBooster to each of these three manifolds. I'm going to try to put some of this stuff under the manifold out of site. You can either keep the barrel valve for the throttle linkage or build something to tie the sets of throttle shafts together. Put a TPS at the end of one of the throttle shafts. So now you have injector bungs, fuel rails and mounts, IAC, MAP, TPS, PCV/BrakeBooster taken care of. One last thing - these manifolds don't have a crossover/thermostat housing, so you need to adapt a remote one. I believe that the large cap HEI distributor won't fit. The magneto does, but I'd get away from that for the street. Air filtration is next. Heavy - hey, it should be a torque monster once it's done!

Yes, it is. There's a beat up old yellow/black AAR Cuda down the street from me. It's a shame, the guy that has it has NO money, but won't let it go, saying he's going to put it back on the road.

Awesome - I love it!

EZ EFI - No wiring harness, O2 sensor or laptop needed!
pparaska replied to SpeedRacer's topic in Fuel Delivery
It's hard to tell what EZ-EFI really is, but I think it's the Carbine ECU that's on that site. It's an alpha-N only ECU. No Laptop (why do people advertise this is a PLUS?) No Thanks. I want Speed Density and Laptop interface. -
Installed TWM induction and Programmable EFI with Pics
pparaska replied to clarkspeed's topic in 6 Cylinder Z Forums
Looks awesome! I suppose since the Cannon manifold has a "crossover", the crossover is sizeable enough to be thought of as a method of sharing carbs between cylinders (i.e., like a plenum manifold), or not, like a true independent runner manifold? The crossover passage OD is small, so I'm thinking it's more like an IR setup? IR or not has a huge effect on what size carbs/TBs to use. If IR, you need alot of carb/throttle body bore area. -
Reading over several sites about injector sizing is interesting. Haltech's site gives the following: http://www.haltech.com.au/injformula.htm "Fuel Injection Sizing Formula After much research it has been found that there are several different formulae used to determine injector size. It appears that most of the various formulae in use are basically identical, with only 2 real variables, being whether or not an 80% duty cycle is accounted for and what the desired Brake Specific Fuel Consumption (BSFC) should be. This is the formula with the correction based on the duty cycle: Flow rate (lbs/hr) = Max Hp x BSFC / no. injectors x duty cycle BSFC = 0.45 - 0.55 for naturally aspirated engines 0.55 - 0.65 for forced induction engines Conversion from lbs/hr to cc/min = lbs/hr x 10.515 Simplified max Hp x 1.807 (nat) Simplified max Hp x 2.136 (turbo) Sourced from: www.autospeed.com" The following is what DD2000 engine astrology software says I'd have with a 10.5:1 406, Canfield heads that flow as I had them tested, the Cam Motion Cam that's on the way, large tube headers with mufflers (I'll be going to 1-3/4" headers), and an IR manifold that flows 2400cfm total. That's 300cfm per stack, about what a good ram tube and 2-3/16" hilborn has been tested to, from what I've heard. 300 cfm may be too little, but let's be conservative. If you add another 100cfm per bore, you get 3200cfm total (what DD200 wants is total flow of all IR runners), and the peak HP goes up to 550hp instead of 525. Like I will be able to use all that anyway! So using 525 MAX hp, .55 (lb/hr)/hp BSFC, 8 injectors and 85% duty cycle, you get: 525 hp * .55 (lb/hr)/hp * 0.85 duty cycle / 8 injectors = 30.7 lb/hr adding 10% would be 33.7 lb/hr and adding 15% would be 35.3 lb/hr I'm thinking 36 lb/hr (at 100% duty cycle as they usually are advertised) will be about right? If anything, it might be too much. BTW, that cam has the same opening durations as the Comp Cams XS274S cam in my 327, and it's 244/250 @ .050" versus 236/242 for the XS274S. Lift is .570s ver .500/.510 for the XS274S, and the lash is less (.010 versus .016). So with the increased cubes and the smoothing effect of IR, it ought to idle like a new Corvette. Note, DD2000 shows an incredible 470 lb-ft at 2000rpm, but it's known to be quite optimistic below 3000 rpm on a NA motor.

Pete, Yeah, o-ring rails most likely. I'd imagine injectors that use o-rings instead of hose barbs are easier to find and cheaper. I'm probably going to need 36 lb/hr. That must have been quite an ordeal. I will be very careful about the rail mounting! Thanks for the warning. I've seen these Hilborn setups with the injectors on the inside. I think it looks cleaner that way: So it seems to fit. Here's a version with them done on the outside: Looks easier. I like the idea of using injectors with a threaded fuel connection, like above though! Stainless tubing somehow looks better on this old school setup!

Congrats and THANK YOU to Pete Paraska for his Comments!
pparaska replied to Mikelly's topic in Non Tech Board
That was a quote, not by me. Good point about emotion vs passion. But if one starts with emotion, and then never goes through the critical thinking process, their emotion becomes their passion, without the irrational part removed. I call that being lazy - not questioning yourself about the things you have feelings about, etc., and possibly changing your position after looking at it from a broader perspective. Well, either being lazy or being immature. The REAL immature part comes from believing that everyone must share your (emotional) belief, e.g., that using other than Nissan parts on a Z is wrong FOR EVERYONE. "...(lunacy) is what makes the world go 'round." -

I always love it when I see a Mustang or Kit Cobra with a non-Ford engine. It shows that the person who built it made a non-emotional decision and decided to use an engine they had on hand or just like to work on better, etc. If someone wanted to put a twin turbo Nissan 4.5L V8 in a Corvette, I'd think they just wanted something different than the next guy, or a challenge. No problems there - parts is parts! I remember reading about "Mr. K doesn't mind the idea of a V8Z" but never new much more than that. I do remember being at the 1995 Z convention and him signing the dash or something on Zman377's V8Z. Mr. K is probably more open-minded than the typical purist. He's nostalgic in some sense, but also enjoys cars IN GENERAL enough to understand the street-rodder's point of view. I'd LOVE to see that article in Sport Z. I think it would cause more of a ruckus than the 350Z styling thing did a few years ago. I'd LOVE to see a bunch of purists get their world turned upside-down by learning that Mr. K himself at one time had the desire to own a V8Z and did so. But even that won't cure the purist. It's a human trait to have deeply held irrational, emotional beliefs. Pete "Where we have strong emotions, we're liable to fool ourselves." -

Guys, just maybe the "bad and ugly" side was tongue-in-cheek? I actually liked the 32 Ford to Z analogy. I agree with Mike about the differences in the aftermarket for them, but I like to go to street rod events (cruise-ins, Ocean City MD street rod events) more than I do Z only events. So I guess I'm more into street rods than just seeing Z's. My Z gets ALL positive attention at street rod events. The atmosphere is more tense about my car at an all-Z event. -

Well then, thanks, Dave . Oops. I didn't mean to let out any secrets! That one slipped. Oh well, no hard feelings, I hope! I was wondering if anyone would post that . That I want to know the story on! Will Sport Z Magazine do a story on that? I'd LOVE to see that documented! Oh, and thanks for posting the article . Guys, really, the magazine is getting better all the time! Subscribe, darn it! I have a two year subscription currently - paid in full by yours truly, and done so without reservation. -

Thanks, guys. Johnc: Actually, the version I wrote had even less hyperbole. But you know how editors are - they can't go without changing things a bit . Seriously though, I didn't mind the edits to my original submission. Bob did a good job adding some bits to the end to point to the poll that they'd taken that I hadn't seen yet and making it look like "Point-Counterpoint". Oh, the things like "C'mon" and "like this guy over here" - I didn't write that either - but it makes for interesting reading to have a bit of the old "point-counterpoint" style . "Jane, you ignorant slut", etc. Wow, I'm dating myself with that last bit! Bob, thanks for giving me a chance at that and some good editting! Jeff Sagan, who is that guy anyway? Drax204Z: Maybe Art Singer (ZSport) could post the text of both sides of the argument here, or put it on their website for people to read and link to it here? I don't want to do it, since I don't want to get into any copyright issues. -
Thanks, Mike http://hybridz.org/nuke/index.php?name=PNphpBB2&file=viewtopic&t=34383 - I'd posted this message on the 30th, since I'd been checking the forums and hadn't seen it by then. I figured it'd be a bit newsworthy for HybridZ.

Heck if I know. Busy around the house and at work lately. The Megasquirt is working on the bench, and I've got a design for adapting it to the Holley Projection harness so it'll be plug-n-play compatible. I just need to finish that (I have the parts) and put the MegaSquirt ECU in the Z and do some tuning. Once that's worked out on the 327, I'll be able to bolt the Holley dual plane on the 406 (once installed) and start retuning.

Recently bought this on Ebay. I'll be converting it to EFI, paying someone to weld in injector bungs, vacuum taps for MAP and IAC/PCV/Brakebooster vacuum, and fuel rail mounting tabs. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . I'll probably go to a more updated set of ram tubes, with a full 270 degree tapered opening (a la Vizard and TWM) to be able to fit it under the hood. I'm thinking of a flat plate at the manifold/tube height and a box attached to the hood that has an opening in the firewall and an air filter in the cowl area. That way with the hood opened, you'll see the flat plate and stacks/tubes. I guess the Holley dual plane (now on the 327), Vic Jr., and Offy CrossRam with twin 670 2bbl Holley TBIs to go on it will just have to go into storage after the Hilborn is on. I'll be using a MegaSquirt ECU.

You'll lose ground clearance over what I have if you put 2x3s below the floor. You're going to have to cut the "frame rail" from the bottom of the floor anyway, and tie the connector to the car front and back, which can be a bit difficult to do stiffly without going through the floor sheetmetal at some point. Welding the cut floor to the side of the connector, or laying it on the uncut floor and welding it probably is pretty close stiffness wise. If you're puting these below the floor, I'd go with 1.5x3 tubing.
-
2x3 tubing, with the 3" side horizontal, is twice as tall, giving much more than 2 times (approx. 8 times) the bending stiffness (vertically) of 1x3 tubing. I put about 1 inch below the floor, and 1 inch above. The part above in no way interferes with my feet, and the 1 inch below is still above some parts of my tightly tucked dual exhaust. Go 2x3 if you can, JMO. http://alteredz.com/structuralmods.htm
