HOW???

[ZaneWayne]

But endearing?

You said that I shouldn't be talking about drag racing because I couldn't afford it. I said I could, if I wanted to devote money to it.........

I obviously don't have the money you do sir, I apologize for that I guess.

I have, and from my experience the case is light, the "guts" are heavy, with lots of areas where friction is created, It also needs to turn a pump to operate all that "stuff". That's why it tends to have a significant amount of drag compared to a stick, and should dyno lower than a stick, especially if it does not lock up the torque converter.

Explain. Because the trans is at the rear of the vette basically with a driveshaft separating it from the engine. Where as the camaros engine and trans are hooked directly up to each other.

I see more drivetrain loss between the two there than anywhere else. Not to mention that the trans won't overheat anywhere near as much on the camaro as it does on the vette for that very reason.

It's not as efficient as it needs to be because of other factors.

A transaxle with tube is far more efficient than a transmission on a shaft. The difference in parasitic losses between the two are nearly as great as a manual compared to an automatic.

The transaxle is located away from the engine. This helps with transmission heat a great deal. The problem with the Corvette isn't the transaxle or automatic, the issue lays solely within the LT1...

It is an LT1 design flaw...

I wouldn't say many... 360RWHP from an Auto with a solid axle, 420hp Coyote and the IRS equipped 435hp is pretty good... 370rwhp from either package probably isn't common.

Quick google search shows plenty S550 auto GT getting over 360hp.

Absolutely! Automatics are less efficient than manuals. No question.

There are many guys that have gotten 12s with their fifth gens. Is it common? No. But the car is capable of it.

so if GM fanbois can rarely get to the magazine results on the last gen what makes you think itll be different now?
we have seen that theres multiple stock GTs 12.5-12.7, is that what its capable of? Your taking GMs Mag numbers as being what its capable of.

But how would the lt1 cause the engine to overheat?

I would say the mustang is capable of mid 12s because people have done it. And I would say that the Camaro is capable of low 12s. The Vette has been in the 11s 100 percent stock. The Camaro has the same motor, just more weight. If you can't see how a SS will be capable of 12.1, I don't know what to tell you.

Look like plenty of 12's and all manual. Didn't see any s550 manuals in the 12's on the list on this site, only autos.

I understand that the wheel hp could possibly be better than the camaro of there weren't the loss in between the engine and trans on the vette because the trans is right there at the rear end on the vette.

No u-joints at either end of the torque tube, smaller , lighter "driveshaft" in the torque tube so less inertia to overcome. The torque tube is in front of the reduction gears of the trans so sees less torque than a drive shaft. The mechanical connection between the crankshaft, the flywheel, torque tube and shaft in the vette is just as efficient as the crankshaft, flywheel to converter to the driveshaft in the maro. Plus the vette is more aerodynamic and has better weight distribution.

True, but there still is no proof that the Vette is more efficient tho.

yea that just what i was looking for, 12.5 -13.1 in just the 30 there .6 spread track/da variance etc etc. Now i didnt say the SS is not capable of 12.1 said its still close enough to be a drivers race. Ive seen lots of 13 sec ZL1/Hellcats

You make all kinds of assumptions when its in the maros favor, and discount physics, that's why you are a troll. You think they put the trans in the rear cause it looks good?

There are a lot of bad dragers.

I never understood the sheer energy put into discrediting so many standards...


If they put the same effort into education and learning... boy... what a world it would be...
