Looking at the new 911 twin turbo all wheel drive it has a base price of $125K it does 0-60 in 3.9, now look at the Vette it goes 0-60 in 4.8 with a base price of $51K the Z 06 Vette does 0-60 in 4.1 and has a base price of $64K if you can buy it for that. Now the Dodge Viper $83K again if you can buy it for that, it goes 0-60 in 3.7. Ford GT 0-60 in 3.4 cost $NA where I looked. Now for me with my 928 S4 with the Tim Murphy SC Kit 0-60 4.1. total cost invested for me and adding $5.5K for the SC kit with what I have in car now including new wheels and X pipe Stereo and RMB under $20K. What I now have is a car that will run with todays Super Cars costing 3 times and beyind what I have in my car this is the deal of deals. I told my wife last week to get a 2nd job to pay for this kit. She is still laughing.

Wolf Pack,
It looks like you have made a good analogy of how great these cars are and the potential they have.
Andrew,
Thanks for clearing up the difference between the 2 G-Tech comparisons. Even against 100+ more HP my wife's AT was faster in the 1/4 mile,,,,, that is until I put drag radials on my 5 spd car which made all the difference
The AT cars can really fly off the line and nothing can beat the shift from 1st to 2nd.
I will be developing the next version of sc kits very soon (early spring) that will incorporate the stock fuel system with the exception of 42lb/hr injectors, a JDS Super MAF, and re-mapped LH and EZK chips.
The stage one kit will pretty much remain the same as it is just because it is soo simple to install. The new stage two kit will include the new injectors, SMAF, intercooler, chips, and will run 10psi. That should put any S4 car around the 500rwhp mark and the GT/GTS cars a little higher. This of course is an estimate and at the time the new systems are released I will provide all supporting documentation as usual.

42# injectors? Hmmm, I think I recall some discussion about the Sharktuner not being able to handle 42# injectors. Why do you need the Super MAF? I'm sure you'll figure it all out.

Now that I think about it, I seem to recall there being an issue with the idle when using 42# injectors. It may have simply been that the idle gets lumpy... I can't find the thread.

One of the main reasons for developing the SharkTuner was to allow the use of larger injectors than 30#. If you try and use a large injector like 42# with a standard LH system, then you have to drop the idle fuel pressure so low that the fuel atomisation suffers, and then the pickup throttle response is bad.
The ST has some clever tricks that allows you use use 42# and larger with stock fuel pressure at idle.
Tim needs the SuperMAF to obtain correct measure of engine load at the high boosts he will be running. DR achieved much the same effect as a SuperMAF by just measuring 1/2 the air going into the engine....

How does it know it is getting 1/2 of the air?

Check out the picture on 928 Specialists website..... if in fact it sees 7/16th or whatever of the air doesn't matter , as the car is remapped with the SharkTuner.

Murph:
I like what you're doing with your Stage II kit improvments. George S. should be talking with you about a possible upgrade path for him - he needs more than his current 438 RWHP to get to his 200+ MPH goal.
