Comes from a guy that has sidepipes on his 928! LMAO

Those side pipes sit very well on that OB- I love the look- Reminds me of a mid- 60's Vette. That being said- I think you should go with authentic Porsche parts in the case of mirrors. If you slapped on some Mitsu Eclipse mirrors - you might be tempted to bolt on the double -decker Pep-Boys wing next.

I don't buy into the theory that you have to use Porsche parts only. If everyone felt that way we wouldn't have any supercharging options or stroker engines for these cars. Where do you draw the line? Is an aftermarket stereo system OK? What about aftermarket wheels? I do believe that if you mod the car you should make it perform as good or better than stock. The same goes for cosmetic mods although these aren't as easily quantified and are more up to the taste of the individual.

I have kept my eye out for different door mounted mirrors that may work on the 928. There aren't many cars that use door mounted mirrors these days. A few to check out would be the new convertible Corvettes and the Mini Coopers.

Heres a link to the C3 mirrors in a complete kit form for $125. Although I think they are manual adjustment type mirrors. http://cgi.ebay.com/ebaymotors/Corve...ayphotohosting

Other manufacturer parts are not the sameas ricer/pep boys crap. It's OEM quality.

I personally didn't like his side pipes. They pretend to make it look as if they were connected to long tube headers when in fact they are only coupled to an exhaust pipe.

RyanPerrella

oh is that how he did it? I sadly always wondered how that happened because i don't know how you get from the exhaust port to the side of the car, with 4 or even 2 pipes. 1 seems more likely. I wouldn't want to know what that looks like from the bottom.

As for mirrors, I think the Mini is almost too recognizable, and they are too big and fat if you ask me. They look like the mini, they dont look like the 928. Last I saw the C5 mirrors or C6 even look pretty nice. But still you have to mess around with them to get them to mount properly and wire them up.

But if your really only interested in painting them with rustoleum then please buy something cheap. You can have a cheap shop paint mirrors for $100 and probably even less then that actually.

True----but not for long.......in fact they've been totally removed for the paint resto. When replaced, they will be connected to individual header primary tubes, as I described many months ago.

actually, you are in the minority as to acceptance of the sidepipe issue, but that's perfectly OK.

largecar379

All you had to do is ask............

(4 tubes to each side is no big deal either........think before speaking)


As you are all knowing of 928 and German engineering, here's the question of the day for you:

in the 928 firing order, there are several pairs of cylinders that fire side by side.

to eliminate this for proper exhaust scavenging, which pipes should be routed to which side of the car to eliminate side by side firing......?

(Hint: It's a math problem.)


--Russ

RyanPerrella

Crap I thought i had you on ignore

Typical, we are in a thread about mirrors and your talking about exhaust scavenging, must be something you read about in the Peterbuilt owners manual or something. Why its posted here in a Mirror thread is beyond me. Of course i am not surprised though.

You can move primaries to exit out the opposite bank, ive seen 928 headers do this before but to my knowledge this just changes the exhaust note. It makes for some cool looking headers but it takes up a hell of allot of space.

largecar379

I believe if you will look further above, our friend in Ontario started in about the pipes, and you joined in right afterwards-----


get your facts straight Ryan, and quit busting on me for your stupid sh** that you yourself started.......

You can't even figure out how to connect pipes.....be it one, two, or four.

Again, you're running your mouth without cause. I'm sick of it, tried to be nice about it, sent a PM to you offering to put an end to this crap, and you continue to go on with your "forum political correctness".


If anyone did a search as to how many times you've posted a comment that was clearly off topic, the numbers would be off the charts--------

Keep your comments about me, my car, my life, my direction.......to yourself.

When you get Randy Venier's job as forum moderator, then you might have something to say about this.

Until then......well, I should not have to school you on it.

As I said before, I am a paid member, and as such have the right to post anything I have an opinion on, regardless of subject, same as you. If I over-step the rules of the game, Randy has every right to remove me from this site. You do not have such rights.

You may have me on ignore, but everyone else will read the idiotic crap you write..........

You're just mad at me because I put wheels on my car that look like yours...only mine are bigger!!!!! (sounds like something you'd say, doesn't it...?)


And yes, if you continue this crap, I won't leave you alone-----ever.

--Russ

largecar379

figured you couldn't answer the firing order question.......

it has nothing to with exhaust note, and everything to do with making horsepower.


good try, but no cigar-

Your wheels are bigger, thats funny, do you have replica 20"ers? If so then maybe

As for your other ranting, well they don't deserve a response really

You also NEVER PMed me, you choose to make a scene which is what your doing again now.

So your talking about changing the firing order? I know they do that on SBC's (2 and 7 I believe) but in order to do it on a 928 you would have to change 4 cams (not just one) and at $2000 plus a set I cant see much benefit in that. Not to mention changing the entire bottom end. Seriously, please tell me what your talking about here, i am sure many other people would like to know. PLEASE ENLIGHTEN ME. There was talk of going to a flat plane crank here before which would be an option on a stroker when you would replace the crank anyway. It would require new cams as well which although would be a benefit to any stroker, arent a requirement, but when you change the firing order, you would need completely new cams for that as well.

I never claimed to know everything about the 928. I do know the engine pretty well, as for tuning it, well no i look to guys on here for info on that, I don't post on topics i don't understand. Now i could be completely wrong here, for your sake I hope I am, but when you talk about changing the firing order in a 928, I think your really going someplace you don't understand. I cant think of anyone thats changed firing order on a 928, but of course i don't know everything. Custom cams on a 928 are very expensive, changing the firing order would also probably require ECU changes and ignition wiring changes as well. Is this what your talking about, maybe i didn't understand your quiz to me very well, please clarify your point?

Seriously, if you can give more information on this that would be great, would love to hear what you have to say on firing order.

RyanPerrella

This comment got you bent out of shape? It a pretty valid point, ive been under my car more then i care to think about and the frame rails are nearly the lowest point of the car. only the CAT itself is lower (on my car anyway)

Sure you can put 4 or 2 pipes out the side under the frame rail but you would risk damaging them anytime you went over a speed bump, unless you raise the car up to 4x4 mode.

If you go with 4 into one then out the side you could run it right behind the swaybar mount, there is some space there I guess. But you could burn the inside tire when making turns. My question was a practical one, i didn't mention the point, i responded to it. I wouldn't think you could get side pipes on a 928. Not that i would want any of course, but i think you would have to compromise allot to get 4 or even 2 primaries out the side's of the car and under the frame rail to make this work.

But what do i know, apparently i cant connect pipe or something you said. Someone commented on how you did it and you took offense to that apparently. I know many people joke with you about the pipes, i do, why cause they aren't stock. But you can make it look how ever you want. I brought up the point of how you did it, i wasn't speaking asthetically, i was talking practicality, you've obviously done it and when someone asks how you get bent out of shape over it and start with the insults AGAIN.

gruffalo

jacquemond has some nice mirrors in their kits. Worth checking out.

RyanPerrella

There is something with the firing order that ive wondered about, yes it does seem out of balance.

cylinders 3 & 7 fire consecutively, as do 2 & 6 and 4 & 8. Those combos are on the same journal so that makes sense that they fire consecutively. However cylinders 1 and 5 are jumbled in the middle of this all and cylinders 4 and 8 fire inbetween 1 & 5 so this breaks the consecutive firing pattern. Since you asked, i found the discrepency to be in the 1 and 5 cylinders.

3 and 7 fire one after the other (cylinders share the same crank journal) then 2 and 6. It would seem that would make for a nice smooth V4 right there. then cylinders 1, 4, 8 and 5 fire and they make a clockwise pattern. Left front, left rear, right rear, right front. Its almost as if the inner 4 cylinders are from a separate engine then the outer ones. I assume this has to do with torque production. I wonder if the GTS is any different actually. (probably not)

I was going to look at the order for other V8's but other engine makers number their cylinders differently, so comparison is difficult at this time.

Still i dont understand how you expect to change the firing order. I am sure Porsche knew what they were doing when they designed the short block. Firing order is probably one of if not the first thing you decide on when designing a fresh from the ground up engine.

F1 engines all seem to have differing firing orders all for different reasons to their manufacturers. They are all 2.4L but BMW goes with a different bore and stroke and firing order then does say Mercedes-Benz. They are different, but if your question is about firing order then i would love to know what your idea was to change it. I don't see a perfect pattern in the firing order of the M28 but i don't see a perfect order in other engines either.

Where were you going with this? Start a new thread on this, I for one am curious.
