freakin sweet, I'm gonna have a few of those printed out!!

No I'm an idiot, it was late and I was overcomplicating the problem. Indicatedrpm is crankshaft output rpm. I had my coffee now.

This bothers me, Only the ill informed care about max RPMs, The only reason I care about max RPM's (which get this, isn't when the valve train is in danger, it's when the engine quits making power) is so I know when my motors quit making power so I should shift. Advertising max RPMs is IMHO akin to HD advertising leather fringe and air cleaner covers. It has no real use, but it impresses the sheep. Spinning an S2K to 9k isn't a great achievement. It's simply the only way they could get a 2.0l turd to make 200hp. HP doesn't exist. It can't be measured, it can only be figured, again HP=TQ x RPM / 5252. So either spin it fast, or make it low. 200hp at 9k rpms is pathetic BTW, my 'bird made 200hp at 2200rpms, (at the wheels) and 433 at 6500rpms, and it was still climbing but in fear for the crappy stock rod bolts, I didn't spin it any faster, there wasn't any need to. And for the record, it also made 403lbs/ft tq at 4100 rpms. which is damn near 3x the tq the Honda mill produces. Torque, it's what moves you.

I'm an idiot, fuge I'm sorry, it was late I've had my coffee now, indicated rpm is crankshaft output rpm. I was thinking each fire is measures, but it's not most systems are a waste spark this is why on LSx motors you have to set the tach to 4 cylinder mode so it picks up every fire and displayed the correct rpm. My appoligies.

Well in a V8 engine you have 2 cylinders at TDC at once, one on the power stroke, on at TDC exhaust, but since there are 4 pairs, they are balanced out and you have a firing event every 90*. On an I4 you still have 2 pistons at TDC at the same time, but now their 180* out, makes for a longer time between power events. also a rougher engine (ever wonder why a V12 purrs like it does?) since you have allot of energy when the plug fires at TDC, but you lose most of it by 110-150* ATDC, and after that it starts to consume power. In a 6+ cylinder engine there are other cylinders to take up this slack at 135*ATDC(V6) and 90*ATDC(V8) so the vibration is minimized since there is very little, to no time that the crankshaft is unloaded. Thus the more cylinders the more time the engine is actually making power through out it's rev., this is why you see rather small displacement 12 cylinder engines, the more cylinders, the more power you can create /rev (potentially, all things being equal, like thats possible but theory is nice) and since the power events are almost constant in a 12 cylinder engine, they idle exceptionally smooth and their delivery is exceptionally smooth as well. You probably already know this crap, I misunderstood you thinking you meant that cars were firing 2 cylinders at once Why 720*?? Because the crank rotates 2x to every cam rotation, only half of the cylinders fire every crank rotation, but they fire every full camshaft revolution. Your RPM's are measured at every firing event of the #1 cylinder, or every full camshaft revolution, so in reality, when your tach says 10k RPMs, your crank is spinning at 20k. There is a reason why V engines are at the degree separation that they are at, 90* for V8's and 60* for V6's. This allows the use of a stronger, simpler common pin crank shaft, while maintaining even firing events between cylinders, thus a smoother idle, and better power delivery. Inline engines such as the 4 cylinder, and I6 cylinder simply put them at even intervals, so that 2 cylinders are at TDC at the same time. This leaves 180* crank separation for the 4 cylinder, and 33.3333 degrees for the 6 cylinder. Although there are some goofy engines out there, MB had a I5 diesel for a long ass time, and now GMC has the I5 in their small trucks. Forgive me, My dad ran a auto shop and I've been obsessed with the internal combustion engine since I was a kid, I've probably got as many if not more books on the IC engine than most people with Masters degrees have/had through out school

going sat to get mine

Have been doing what? I can't think of a single car that fires 2 cylinders at once. V8's are 90* appart because 720/8=90, that gives a smooth firing order and a less rough idle. There were some v6's that were odd fire like the first 4.3's they kept the 90* V and the common pin crank from the 350 and that's just how it worked out when they pulled two cylinders, but eventually they changed it to a split pin crank to get the even fire back. Some old buick V6's were odd fire too, but for different reasons. Mainly lack of understanding and not power.

eh, looks to be on par with the 05 ZO6, and still quite away behind the ZR1. Not impressed.

I'm still not sold, your and avid 'bus hater, and sign up as another name, even fronting as a gixxer owner to bash the 'bus and stir up a little shit before your big return is exactly your MO, right KawiFan? Either way welcome back, I think at this point you need an I tro thread -

We're freakin asking!! No BEGGING!! Where the feck is it!! -
Not to be a prick, but New Enough is selling them for $145.99, new. I'll offer ya $75 for them.

wow, here's the bottom line, aside from looks (taste is optional and objectional) if you've EVER riddin a 'bus you wouldn't be running your cock holster like that. And since ignorance is bliss, I'm sure your in pure extacy on your bike. I've owned and ridden every bike in the GSX-R lineup. The 'Bus is heavier and takes actual skill to ride properly and to push around the corners like a man. I'll put the same offer out to you as I do everyone else who thinks a 'bus can't turn. Rt 9 this spring. Aside from a shift light and some soft luggage my bike is stock, later Ninja Nick. -
Just tell them what you did, Honesty ls worth way more than a measly $75 dollars. Besides your working for free, and you fixed a problematic computer that a paid employee fubared, Your saving them money. say, "hey I fixed that problem with such and such a computer, but i put my finger through the fan and busted a blade off, what should I do?" They will tell you to put a new fan in it an get started on the next tihng on your list. Hell we had a guy new guy here at work, like his 3rd day, put a over head crane hook through the windshield of a brand new truck we were converting. Talk about shitting bricks, he almost walked off so he wouldn't have to get told he was fired. Boss just asked him "what the hell do you want me to do about it, call and get a window for it, we can't sell it like that"

Man I wish I had a spare grand laying around I'd love to rat that thing out, and it's perfect for it, you take payments

bring on the snow! TGFJ (thank god for jeeps) were supposed to get another 5-8 over the next two days I love snow

my friend just got THREE of those exact same emails, he's selling a bed liner from his truck and the first guy sent him a check for $3000 and wanted the difference, said his secretary screwed up, second guy said the check was in the mail and same thing. Why the he'll would someone in Indianna who's moving to Cali want to buy a $150 bed liner from the far east side of Ohio :-/ idiots.

Well then so be it, just until now I've not heard of and issue other than 'I was dpi g a stoppie' I was hit a curb @ 60' ' I hit a cow' 'I was doing a wheelie' so I never thought there was a serious issue other than abuse.
-
i mean it's pretty obvious that their cracking in examples of abuse, and out side their design limitations. Oh well.

Not everyone, but Islamic Extremist pretty much covers that like a tarp. I'm not gonna get into it with ya JRM Your a good guy and I like you, but out views on this are WAY the hell on other sides of the map.

Those laws only apply if BOTH sides follow them. If their going to cut off the heads of out innocent civillians then I say all bets are off.

Well, I'd wager to say that well appoligize profusely, pay them between $8-10 mill apice and let them go. The terrorists have been saying for years their going to take us down from within.

Back seats are tacky, I can honestly say I've never done it in the back seat of a car. I cannot say however that I haven't done it while driving down the road...
