Turbo Tech Info

The ultimate task of any turbo upgrader is to balance turbo response with ample power. Most of the turbos listed here are high HP, low response setups. Just because a turbo can produce enough CFMs to give you 450HP, that power might only peak at redline. If you are building a drag car, you want to balance the turbo to be most efficient from about 2000rpms before your redline to redline. In drag racing, once you get into your powerband, you most often stay there and revs only drop 2000-1500 rpms per gear. If you plan to drive the car primarily on the street, you want good response. A turbo that gives you 350-375HP from 4000-8000rpm and good response might very well beat a 400-450HP car with a bigger turbo. Your turbo will be in full force 2000rpms BEFORE his and by the time he starts to catch up when his turbo becomes efficient, the race will be over. It doesn't look as impressive on the dyno, but a broad powerband on the street will be most effective.
