Best sub $1k power mods?

[edc]

The Road and Race poster was mainly on boxa.net and gathered a lot of info from users there doing the tried and tested mods. But to answer your question no. You won't get +50bhp whether at the wheels or at the flywheel with those mods. I did them all and put the car on the same dyno at each stage and posted the graph with each mod stage over layed including a baseline run. You'll note the Road and Race vids "layer" up the mods and power on an assumed 260bhp start point. I have seen standard cars run anything up to 35bhp different to each other depending on their maintenance.
