As stated above my LS1 powered car was dynod at 317 RWHP with just the wortec catback and a remap. I understand that I should expect even more from a remap now the headers have been fitted. Am I being optimistic?
When mine ran that same exact setup it made 379 at the flywheel on Mark's dyno. Wortec claimed 390 in their literature I think. That's about 300 at the wheels so you are bang on the money I'd say. Headers are worth about 20whp but you'll never notice it.

It depends on your build. On a standard setup it makes little difference and bigger isn't always better but as numbers rise and you add FI it becomes a restriction. The easiest way to get the best from your motor is to decide on a power level and build a package to achieve it.
What a sensible man

yes and after 18 months and numerous changes he hopes to drive his car soon
You cannot rush these things it seems! It's been nearly a year since my build started which is slightly less than Harry's took. To be fair though he did suffer one engine failure during the build.
