smoked on the first run!!!

[fastpakr]

Even the TSCC 750's aren't consistent from year to year. The 82's intake valve duration is a bit longer, among other things (dropped from around 12.25 to 12 flat in the 1/4 from 81 to 82).

[Nerobro]

Not many Camaro SSs could do that, either, only the top optioned ones could come anywhere near that. Actually that sounds more like COPO territory than 'normal' SS territory. The Viper, by the way, can do low 12s, even quicker than the 427 Cobra. There are some Vettes that can get down there too.

I'm talking the "new" camaro SS. Not the 60's ones. People have... pretty wild imaginations as to how fast the old cars were. The horsepower numbers were inflated, and well.. just look for some REAL 1/4 mile times for those old dogs. They had lots of torque, but not the horsepower. Just a note, the fastest number I could find for the new camaro ss on the net was a 13.2

Ok ok, the viper is low 12's. :-) the 427 cobra isn't that fast because of the tires available. Not that you'd ever actually come up against a 427 cobra. But you might come up against a kitcar, that's lighter, has wider tires, and better suspention than the original. I wouldn't race one ;-) In anything short of a hayabusa or a zx12.

not that I considder it a reliable source.. http://www.primo.4mg.com/photo.html Those numbers seem sane. And agree with what I remember.

Keep in mind, that modern 600's are in the 10's. All the top bikes are in the 10's now. Now wheelieing is the limit ;-)

[Hotblack]

Oh yes the modern 600s will smoke just about anything on four wheels, certainly any 'regular production' car. The 'old dogs' post better times now than when new, if they take advantage of modern rubber and suspension. I remember some testers cracking off high 12s with a Six Pack Super Bee consistently, and being really happy at what a difference those things make. I think it was pretty much stock other than that. Even so I think the older engines were much less consistent car to car, day to day. Modern computers can really optimize things for the conditions. I'm not too up on the new iron, but I know it's good. Big Blocks are a thing of the past in passenger cars, but imagine a Camaro with a modern 454 treated to all the modern stuff the 350s get. I suppose handling would suffer, but the acceleration would be insane.

Horsepower ratings for those old cars were all over the place. Lots of them were way over inflated, some were way under. Sometimes I guess manufacturers wanted to slip something under the radar. Often they will compute a 'real world' horsepower using vehicle weight and trap speed, and those numbers are most often a lot lower than those claimed by the factories. I remember being impressed that the Buick GSs had a pretty low discrepancy that way.

So 67 for the 2 valve 750? Sounds like what I expected. Someone said around 72 for the TSCC I think. Seems to show up noticeably on the strip. I've seen weird numbers for the Kawasaki Z1s too like, 60.... I can't swallow that one. Did someone put a sock in one of the carb throats? I think I saw 80 also, that's a little more believable. There's just a universal fudge factor everywhere you go when dealing with information. Very frustrating.

[earlfor]

Yep, 67 for the 2 valve and I believe 72 is correct for the TSCC.

1200 sporty? Yes browndog, we gotta get you a tune up
Trust me on that.

Just to try to save face with my fellow GSers:

My bike is out of tune---possible.

My racing skills are at fault---very possible.

Weight difference---yeah, thats it, weight difference. Thats what I will blame it on.

Not sure of the weights of each bike, but I would be willing to bet that the GK weighs at least as much as his '04 Sportster (even though I have the GK stripped). But my buddy weighs half as much as me...literally!!
He might be about 135-140, I am pushing 3 bills!!

Does that excuse work for everyone?? Please.

Also keep in mind that the GK is geared for highway use, not for acceleration. If it had been a top speed run you probably would have wasted him. I've raced a few harleys with my old 700, and did pretty well, though it was a pretty close match up sometimes. The problem is that to launch the 700 well you need to hold the revs up to 5 or 6 grand before you start the clutch out. Something about that seems wrong on the street. The harleys have so much torque they can just hammer it from idle. That's why they tend to get a jump, and with the street races I've done they tend to last only about 300 feet, as after that things get too out of hand.

Oddly enough, I don't get challenged with my current bike on the street. I think the 700 looked more like a bike they could beat. Now I just go to the Dragstrip.

For heaven sakes man change your badges to read 750cc. That will get you more action.

Yeah I gotta except that one it's all part of the "I can make fun cause I are one" thing.

But! I am telling that even with the likes of lard butts like you or me on there the GK WILL slap even the newest 1200 custom in the quarter and even harder when stretching out the top end. My 1000 can do it, with ease. Your 1100 needs a tweakin. There is more bike there than you have been experiencing

Interesting idea and all, but I'm pretty sure as soon as anybody hears my bike, they would know it wasn't a 750. Of course I could shut it off at the line, let them get a good head start and then have some fun :twisted:

[scotty]

I dont know how much louder yours is than mine but on the street the harley boys usually dont know anything except that they are rideing a harley.

[HiSPL]

Thats funny.....

[AOD]

the new 600's and bigger sound really sweet with a nice exhaust. the high compression they use on the motors gives them that race sound you only expect at a track.

Now I know what you guys (and especially Scotty) are talking about, that the power band seems to be at really high RPM's. I could hear the engine noise change, as in some serious power kicking in.

my 550 does the same, it gets decent midrange power at 5000-6500, at 7000 it has the most exotic melodious tone, and above that the thing screams. the little inline 4's dont make torque and HP until you get them spinning fast, so get on it! be careful though.

you can try this if you want as well...i can do about a 4000 RPM launch with my 550...safely. gas it, and smoothly, but quickly engage the clutch and it takes off FAST.

~Adam

[Nerobro]

Mmm that high rpm rush. Such a fun feeling. I didn't think I'd ever get that "arms being pulled out of the sockets" feeling from a 550 :-)

[Hotblack]

I do remember the 550 having a pretty good rush though, when the carbs were in sync. Definitely enough to be fun. The 750 gives 'arms stretching' sensation. The 1000 probably has them leaving the sockets... The Hayabuse would probably leave you with blood squirting from your shoulders like a Monty Python nee Sam Peckinpah scene if not for the modern tucked in riding position. I'm not surprised that modern sportbikes don't have a nice flat bench like my 750... Armorall THAT!

[lhanscom]

I think with a bench seat with some armorall put on it, you could hang onto the bars as tight as you want, you'd still be flying superman style on the bike.

Maybe that's what happened here?
