supercharged 0-60 numbers

Axtellz,
Here are ten cons:

1. GT interior and dash appears to be cheap looking and outdated. It needs a complete workover in design.

2. GT handling... it plows into corners.

3. The rear needs to be udated with possibly independent suspension.

4. The manual transmission became too much! Shifting at almost every intersection became a real exercise in futility. The 8 speed transmission won me over, besides,the 8 speed shifts faster everytime and is much more fun to drive.

5. The ISF is faster in all aspects and doesn't draw attention by law enforcement like the GT500.

6. Lexus build quality and reliability is much superior to the GT500.

7. ISF is limited production vehicle about 2733 made for the states as compared to approximately 10,000 Shelby GT500s made in 2007 and another 10,000 being made in 2009. Go figure!

8. Gas guzzler tax $1300 vs. $0.00 for the Lexus ISF

9 Top speed limited to around 140 mph vs. Lexus ISF approximately 172mph.

10. GT500 already supercharged vs. Lexus ISF room for even more power.

These are just a few reasons.

Hope this helps!

american cars are straight like cars, but cant handle for sh1t in a corner. that and you get what you play for in terms of cheapo plastic materials. one of the few american cars worth owning is a z06, and you would think that they would incorporate some of those characteristics into their other vehicles.

a supercharger will improve your 0-60 as i previously stated, but not by that much. example 1. the E46M3. 0-60 is 4.8 seconds stock at 333bhp. with a Active Gen 3 kit, you are now making closer to 550-600 bhp, depending on if you map the car for 91/93. you have close to twice as much power, yet your 0-60 only gets better to 4.1 over a STOCK m3? letme just throw in you can get your 0-60 from 4.8 down to about 4.3 without doing ANY power mods, just gettingyourself gears. a 4.10 limited slip differential will get you off the line that much faster.

so lets examine this again

STOCK m3 WITH GEARS 0-60 4.3 seconds
AA S/C Stg3 M3 0-60 4.1 seconds

you may be thinking well why wouldnt i be even faster with gears on a Stg3? because when you make that much power, you will need to go back to the stock gears, which in this case is a 3.64. if you had 4.10s and a Stg3 supercharger, youd never get that power to the ground or be able to shift in time. all you would be doing is spinning in place basically.

so lets take this a step further and say u went to an HPF 750 turbo kit. yes folks thats 750bhp. you now have almost 2 1/2 times the power you did stock. do you know what HPF claims their kit to be in terms of 0-60? 4.1. just like the AAStg3. now you ask, how does a car with 200 more hp do the same 0-60? reason. traction. with 750hp, you will not be able to go full throttle off the line. if you look at the 1/4 mile, stock m3 runs about a 13.3, the stg3 runs about a 12.1, and the hp750 i believe crossed the line at 11.954

there was a graph i saw on m3forums one time about optimal gearing for X amount of power in that car. ill see if i can have a buddy email it to me so i can post it. very interesting.
