The ford dealer called me yesterday. They have a GT500 in stock (white w/ black stripes.) that's car is bascially a blower upgrade away from 800 rwhp!!!

I just finished testing wheel-speed based boost control in Haltech and it works quite well. You can run as low as wastegate for lower speeds/gears, and then ramp in as much boost as you want for higher speeds. This will be another free update, slated for next week.

These 500+ beasts are great, and I'm sure are awesome highway monsters, but what is the best compromise for 0-120MPH, keeping the car in control, etc? Would you want high horsepower with lower torque? Shorter gears?....High horsepower, high torque, long gears?
Please discuss.
Please discuss.

Powerbands affect the "street limit" also. A big TT kit like the JWT 850 can plant 700whp in the summer in 2nd, I cant even do that at much lower power levels due to having so much more TQ sooner. A 450whp Vortech will hook much better than 450whp TT kit. Its all driver preferance, and ability. I had a hard time at first with my car in 1-2, Id go WOT and just go sideways. Once I learned that part throttle is faster in some situations I became a better driver and didnt worry about starting from 2nd gear. Takes seat time, you can peddle 800whp if your good

yeah it takes some getting used to with getting a feel for the car and its tires. As a driver, your right foot is the best source of "traction control" on a car without traction control (The Z's is way too invasive to be useful)
But I have to admit, I really would rather push the gas pedal down all the way and get the maximum acceleration available at that time with the available traction vs pushing it down around 70-80% and trying to feel when the tires are about to break loose. I'm not opposed to a "good" automatic traction control system if one ever gets invented
The new exige S has an interesting one that compares the front and rear tire rotations and you have a dial that you set from 1-10 that relates to how many degrees difference before the engine cuts back proportional power

proportional timing would be sweet.

That's why I said that.

Streetable power really depends on your skill level and what you can handle. If you don't know what you're doing, 400whp will be too much for a novice RWD driver. Someone with experience would be able to handle a 600+whp car on a daily basis. Drive wheels are gonna be another issue. I can handle 800+ to the wheels, since I'm using all 4 (and yes, I have driven an 800awhp Evo, and it's easy to work with). Trade off then is gonna be down low torque. No traction issues once you get going though (as long as you have the proper tires).
I'd personally say 500-600whp is a great range to have fun on the street and be relatively in control at the same time.

I have been running 295R35-18 PS2s and the difference between 2 degrees and 1degree is night and day. In a straight line I was only useng 75% of the tread. Now I'm moving up to 31530R-18s. Constantly hazing the rears in 3 rd gear is fun for a while but hurst the wallet.
