that was most likely due to boost lag, however modern turbo's really don't have this problem. the Bearings used nowadays are 100 times better and spin up quicker, even at low engine RPM's.Raxstone said:Back in the day (around 1986 or so) when Koeing modified Ferrari's -- there was a 512TR (Testarosa) they did which I always thought was the best way to go. It had a supercharger for low rpm grunt, and a turbocharger to pick up where the supercharger ran out of flow. I also remember seeing a 70 chevelle with a 454 and a 6-71 blower, running twin turbos as well. That would have been a nice set up, even sans intercooler.
