wow, so your Evo is faster than any production car on the planet 0-60, even the McLaren F1 or Ferrari F50?

Gotta be a mistake. I've seen AWD Porsche 911 Turbo's run 3.4-3.6 0-60, I don't think our Evo's can be that fast.

Don't mean to sound dissenting, but 0-60 in the 2's are just unheard of in anything I've read about having a combustion engine.

If it's true, then

 

I don't want to sound like I don't trust your claim, but that does appear to be a little unbelievable. I was wondering if there is an engineer out there that can calculate the 0-60mph time based upon HP, weight, gear ratios, etc....

It just seems impossible that a MClaren F1 can't match those 0-60 times and the ENZO would be left in the dust with a sub 0-60 in your EVO, and if I'm not mistaken, both of those cars run faster 1/4mi times than you posted.

Trust me, I do hope you are right. If you are, congratulations.

 

Sub 3 second 0-60mph dashes are quite impressive.

I have a question. Do you guys launch on 2 step? If so, how much boost do you guys build at the line before the launch? Best I've gotten (no 2 step) was 1.700 60 foot, on tires that had 15K miles on them (almost dead).

 

I assume the 0 - 60 data log numbers come off the wheel speed sensors and therefore would require ZERO wheel spin to be accurate ???

Does the AEM set up have any traction control included??

 

yeah im pretty much doubting the time too.... is it a calculated time or is it estimated based on your 1/4 mile time?

my friends dad owns a porsche GT2 modded to about 600hp and its definately over a 3 second 0-60

 

Just FYI the EMS has a very nice datalogger which is quite accurate. And I would highly doubt that you would be seeing any amount of wheelspin at sixty. To play the devils advocate.... even if you were to read them off of the factory speed sensor your times would on differ +/- 1 tenth.

 

It would be most fair to compare the car against the others using the same testing methods under the same conditions. I'm quite sure you can get the McLaren or ENZO to spin the tires off the line and that this doesn't help them in the 0-60 department. However, I didn't have to calculate the time from distance, HP, etc. I simply looked at the vehicle speed vs. time it took from 0mph to 60mph as viewed by the vehicle speed sensor. I also compared the length of time of the run on the log to the actual pass to make sure they cooresponded. They do. I'm sure there is a possibility of error here... plus or minus, but I would believe it to be very very close. It is very important to remember that the AWD cars are tenaciously quick in the first 100 feet. Also, keep in mind that with a 1.62 60ft time, I was accelerating the car very efficiently. I personally wouldn't doubt for a second that the EVO could decimate a McLaren off the line in a drag race. Would the McLaren suck the doors off of a stock turbo'd EVO by the 1/8th mile and run away from it? Certainly it would. I remember when we were seeing our AWD DSM's run against Eddie Bello's Turbo'd 911. We could get him thru 1st gear into 2nd and then he'd just pass us by and click off a 9 second pass. Just because you get the car out front more quickly doesn't mean you can stay there. I believe these figures to be accurate.

Take care,

 

Could that low 0-60 mph time be due to wheep spin / the computer thinking it's going faster than it is or was wheel spin not an issue 2.5 seconds into the run?

 

Not SO unbelievable

See

http://www.car-stats.com/stats/shows...seby.aspx?by=3
and
http://www.maxpages.com/corvettehome/0_to_60_mph_times

notice that these cars are running 3+ 0-60 and 11.8+ 1/4. With the awd I would say it is possible.

I saw the thread right after he posted and checked it out. Unbelievable, yes... impossible.. no. Add in a couple of 10ths for error and it seems reasonably possible to me...

see the physics of a perfect world

s(t)-s(0)=v(0)t+1/2*a*t2
s(t)=60'
s(0)=0
v(0)=0
t=1.6
acceleration then = 41 ft/s^2

v(t)=a*t
a= 41 ft/s^2
t=2.6s
velocity at 2.6 seconds = 107 ft/sec *3600/5280 = 72 mph

reducing for non-constant acceleration and driveline drag this doesn't seem so out of whack.

my 2 pennies

 

BTW... I can see wheel spin when it happens. You'll see a cooresponding rise in engine RPM and then it will pull down when you gain traction. I did see the wheels spin to 60mph and then hook and reduce. I then moved along until it showed a steady acceleration in speed... I then noted the time that it achieved a true 60 mph. I do have launch control setup in my calibrations, but I have yet to use it. There is more than enough torque to blow the tires off now if launched too aggressively... I see no point in leaving under boost on the stock factory tires that we are using. Leaving under boost is also very abusive to the driveline. I didn't want to walk back to the shop from the track! Hope this helps keep things clear.

 

Careful there, I've done 2.89 0-60 on a modified ZX-9, and there are guys faster than me around here I am sure have bettered that. Not only was it internal combustion, but with carbs. Maybe you meant 4 wheeled IC.

 

A car running mid 11's with a 0-60 of 2.95 sounds crazy. I would need proof of this. The Norris Evo had 600+ hp with a 0-60 of 2.7. Can Buschur comment on this.

 

Read Tym's above posts, he basically explained it, and offered proof. It is well known that AWD cars have the ability to get off the line exceptionally quickly due to the traction/minimizing of wheelspin. A much higher horsepower AWD car like the Norris Evo reaches a point where even AWD cannot overcome the tendency to spin em up. Hence the marginal reduction in time.

 

Its a facinating intelectual concept indeed!!! I think the best way to test the 0 - 60 time is with a radar gun

I know iy has to be damm fast as I am doing very low 7 sec 1/8ths in the mid 90 mph range - which much yield a very very low 0 - 60

BTW - my buddies who built my last motor who are master ferrari techs and who have driven Enzos confirm that my Evo would chew up ANY ferrai to about 80 mph - then the Enzo would come blowing by like a jet plane and after 130 or so it would start to disapear very quickly

AWD is a great advantage off the line but only goes so far

Wonder what the new Bently GT will do at the drag strip - bit heavy though

 

I don't see why Tym would make this up, I would say with the 60 foot he pulled it would be under 3 seconds. Also I know the car will do it with slicks on it.
