The car we tuned had stock manifolds. Seb's Run #5 shows the 530BB turbos without manifolds tuned. The numbers are 462hp and 491 torque, which are both lower than what we acheived but still in the same pattern. It does show a substantial benefit with using the aftermarket manifolds. So does any one have any other dyno charts of 530BB turbos with stock manifolds to compare this car to? The evidence I have seen thus far leads me to beleive these turbos are a sub-par performer for their price and not to spend a couple hundred dollars more for 2530's would be ludicrous.
