this is info i grabbed quickly from a list that was compiled from various sources.
2001 Chevrolet Corvette Z06 4.6 13.0
2001 Chevrolet Corvette Coupe 4.8 13.1
2002 Chevrolet Corvette Z06 4.1 12.5
2002 Chevrolet Corvette (Lingenfelter 427 twin turbo) 1.97 9.24
if that is the case then i can see how the average dude would run 13’s in either a 01 or 02 Z06…
magazines quote the best times with professional drivers after several attempts. it is really hard to get a sick launch AND make perfect shifts at the optimal times etc etc etc…
there was over a 0.5 second variability in my times and my best time was still alot short of what it should have been.
i did 14.0 at 110 and am told that a 110mph trap speed should be good for a low 13, so i must have been sluggish somewhere else. reaction times were low 2’s.
Mag times aren’t typically the fastest times. At least as far as the general interest mags (e.g. Car & Driver, Motor Trend, Road & Track, Automobile, etc) are concerned, they usually get some of the slowest times. But it’s also because they run 100% showroom spec and try to be consistent between cars… and also cannot become experts in such short time on each individual car.
Also, reaction times have nothin to do with your ET/trap speed. The timer doesn’t start until your wheels pass the light beam.
You prolly meant low 2s 60ft… I dunno what a good 60’ is for the kind of rwd turbo setups 240 guys run. Seems to me like 1.x might be a little ambitious?
in 240 land 1.8 60’ times are not uncommon and some 1.6’s have been recorded with even street tires (if you call an ez street a street tire). This is of course with damn good drivers who know the car like the back of their hand.
LT2 that’s in it is junky, ECU TB control, 350lbs bare with just the PLASTIC intake mani on it, no headers or TB on it… still using old 1950’s SBC geometry… if that’s the best chev can do I don’t think mazda has a thing to worry about when the new rx7 rolls out… corvette = over priced, over hyped, over weight, out of date, crap.
Most major car companies are switching over their cars to drive-by-wire Throttle Body control so I’m not sure why you list that as a negative? The LT2 isn’t used in the corvette. The regular C6 vettes use the LS2 which replaced the LS1 in the C5’s. The LT series of engines are used in GM trucks and a different beast altogether. The new C6 Z06 uses the almost-all-new LS7 engine which is an all aluminum design with dry sump oiling. It is nearly an exact copy of the engine that is used in this:
The C6R. The LS7 feature include:
-Unique cylinder block casting with large, 104.8-mm bores and pressed-in cylinder liners.
-Forged steel main bearing caps
-Forged steel crankshaft
-Titanium connecting rods
-11.0:1 compression
-Dry-sump oiling system
-Camshaft with .591-inch lift
-CNC-ported/polished aluminum cylinder heads
-Titanium intake valves and sodium-filled exhaust valves
-Titanium pushrods and valve springs
-Hi flow intake and filter
-Hydroformed equal length 4-1 exhaust headers.
-Every engine is balanced and blue printed.
As for the weight issue I’m not sure where you get 350lbs for just the block? The old LS1 weighed 503lbs, fully dressed (not a short block) with the Tremec manual tranny attached. The LS7 will most likely be lighter still with most estimates being in the 450lbs range. Fully dressed. With Tranny. The whole car weighs in at a little over 3000lbs.
If the next RX7 (if there is ever going to be one) is as underwhelming as the RX8, Mazda should be the one that’s worried. At best it will tangle with the other lower powered sports cars like the 350z, M3, Mustang GT etc.
There is no way a new RX-7 (like Mike said, if there’s ever gonna be one) is coming anywhere near the new Z06 in terms of performance per dollar.
Yes, Mazda won LeMans and they should be applauded for it - but that was 14 years ago. Watch the C6Rs tomorrow at LeMans and you’ll see for yourself- the new vette isn’t the crap you think it is.
And yes, the vette weighs over 3000lbs. It also has 500hp and 475lb-ft of torque, available across a USABLE rpm range. Its power to weight, as the article states, is 6.2lbs / hp. When was the last time Mazda came out with a car anywhere near that figure?
If the new rex comes out it will no doubt be similarly priced to the C6 Z06 and no where near in terms of performance - OR it will perform similarly and cost double. We’ll see who’s overpriced then! :-s
To Rotorkami: I thought you were supposed to be the one here that knows what he’s talking about. It’s hard to be good at what you do if you’re ignorant. Do some research.
well considering I’ve built a pair of TT setups fora LT2 for aircraft use, I’ve probably been up close and personal with that engine way more then you have… I get ALL the info from the aircraft eng. … and bud, if thier is ONE thing that aircraft builders pay VERY VERY VERY close attention to it’s weight… the short block, with JUST the plastic mani on it and nothing else was 350lbs give or take a few oz.
“well considering I’ve built a pair of TT setups fora LT2 for aircraft use”
This Thread Is Worthless Without Pics!?
I’m sure Ian is right about the weight of the LT2 engine because of his superior engineering backround however, all the engineering backround in the world can’t change the fact that the LT2 engine has never powered the Z06.
No problem, I’m sure you are 100% right and have a lot more experience with that motor than I do - I’ve never done anything more than go for a ride in a corvette, but ignorance is still something you’ll need to overcome in this thread because the point still is that the z06 is just about the best bang for your buck available.
I highly doubt Mazda will sell a $160,000 CAD car let alone one for 80 g’s. If a new RX-7 comes out it will likely be less then 2/3’s the cost of a Z06. Given the FD’s track record, you’d have to be nuts to make the kind of statement you made above about a “new RX-7”.
You said that “there is no way a new RX-7 is coming anywhere near the new Z06 in terms of performance per dollar”…this is where I disagree.
Call me crazy, but I’m willing to believe Mazda/Ford could make a 2600 lb., 360 hp car that would keep up with the Z06 in the corners for under $80,000.
It would be a bad business decision, but it’s well within their capabilities.
^^^ could possibly make and currently selling are two very different things
Any company could make an amazing super car and sell it for $1.20 but it would be a bad business decision indeed … so i think right now in the real world the corvette is winning the bang for the buck race.
