xfyred,

I was looking at it from some of the rule of thumb calulations.

If you are going from 215 to 415 415/215 = 1.93 which is 14.7 * 1.93 = 28.37

28.37 - 14.7= 13.67 pounds of boost roughly.

vortech states that a LT1 ( sorry these are figure I have worked with forthe past 3 years)

stock LT1 = 300 hp they advertise 6-8 pounds of boost depending on where you run to redline...

300 + 6 pounds of boost =

14.7+ 6= 20.7 / 14.7 = 1.408 pressure ratio

so then take that pressure ratio and multiply it by the BHP 300* 1.408 = 422 HP

Thus my thoughts were that more realistically

215 *1.54 ( 8 pounds of boost) = would net around 332

I agree anything is possible... you would probably also need to factor in a water alcohol injection system. It added almost 50 hp to my Corvette alone keeping the intake temps to a reasonable level. Also you would need a means of controlling the timing, I haven't looked THAT deep into it but there is probably some sort of BTM system to pull back the timing a bit at the higher end. Although dropping about 4 steps colder on plugs and water injection you may not need to do so...

My website is : www.ndneyes.com/mo

I use a program called LT1 edit to modifiy the fuel and the timing along with an MSD BTM which can pull up to 15 degrees of timng ( heaven forbid) for the most part I only need to pull about 1 degree per pound of boost in the summer where here it gets 106 degrees in the day. I just recently added an alcohol / water injection system that has flat woke up this car! I'm using a stock block no cam and it is running 10.5 :1 compression. I'm pulling 10 pounds of boost at 6000 RPM and have been seeing about an average of 535 horse. 0-60 in 4.4 seconds with two people in the car. I supliment the fuel with a in tank bosch high output fuel pump and a T-Rex inline fuel pump to give me a possible 50 lbs of fuel at up to 100 psi. I use a Carroll super charging Superpumper TM that modulated the fuel to the amount of boost so that I can run lower fuel pressure on the normal street driving and when racing can push up the fuel pressure when under boost. I'm feeding it with 36 pound injectors and the fuel pressure is about 75 pounds to give me a 12.5 :1 AFR basicaly from 2000 to 6000 rpm.

If you have more questions feel free to as...
