Turbo's

[cgb1970]

Am I right in thinking a stage 1 turbo is better for a tight twisty track than a stage 3 turbo regardless of the drop in bhp

yes, i noticed it at the rally special events.

first i hade stage3 turbo, which is not good for the very twisted tracks.
i tried the stage1 turbo and car had more power in lower rpm's

If you use manual shift on the tighter tracks you can get away with a stage 3 turbo. As long as you keep your rpms above 5,000 rpms or so. Then from there is just a matter of battling wheel spin.

Depends on the car tbh...

I know the S13 240SX I tuned for a friend lost about 50 lb-ft of torque from the high-RPM turbo for 20hp or so more peak power and wound up far faster with the mid-range turbo (which gave the highest torque).

Ultimately, the way you tune your car depends on how you drive. And yes, a mid-range turbo will greatly improve torque compared to horsepower. How does the torque compare on a stage 3 turbo'd S13 to a non-turbo'd S13. All that the different stage turbos affect is amount of psi increase inside of each cylinder. The turbo needs exhaust air to begin spooling. So, bigger turbo requires more exhaust air to effectively provide more intake air.

Look at me, I went on a rant...what I am trying to say is that the most effective tuning of any car depends on the driver. There.
