I wonder if I'm going to need a single turbo to beat my brother's new RX7 purchase. He should have it shipped here in the next 2-3 weeks. It's already setup. Moddified V8 Chevy. 375BHP and a whopping 380lbs torque. Be tough off the line. Does 0-60' in 1.69 with street tires. After that I hope to beat him at the 1/4 mile, we'll see. I can already beat his '66 Hemi 4-speed.

I used these dyno numbers for my software program to get 1/4 mile times. These are some of the times the program put out. Remember in a simulation everything is optimum like launch rpm, shifting, etc. So the times are very good. It's just used to give relative numbers between dyno curves.

RPM T04E TWIN TURBO

0.5 20 30

1.0 25 40

1.5 30 50

2.0 45 60

2.5 65 90

3.0 110 140

3.5 165 170

4.0 230 190

4.5 290 220

5.0 320 280

5.5 350 310

6.0 370 340

6.5 380 350

7.0 400 350

7.5 380 340

T04E Twin Turbo

0-60' 1.61 1.74

0-660' 7.60 95.12 8.00 90.05

1/4 mile 11.86 118.41 12.45 112.35

So with these numbers it looks like the single turbo is pretty good.
