is there ever any reason to set the cam timing like this?
a mates car wasn't making power even after the shop had done a few dyno sessions with lots of troubleshooting.
to me its obviously the cam timing but i don't want to jump to any conclusions as its such a strange table, got me second guessing if its for a specific reason :/

I don't think it's going to be the cause of it not making power, but it's definitely going to use a lot more fuel while cruising with that table. Not sure why they've done it, maybe thinking it will feel more responsive under light throttle / load advancing the timing like that.
Looks like a B-series car, definitely not strange and is ideal for a race application. Won't be the cause of the issues.
Its just a basic bolt on street car lol kinda seemed like they were overcomplicating shit, when i saw that they had set max knock retard to .05 i kinda wondered about allthe other changes theyd made.
Cheers guys.
Whats is the result of that cam timing that makes it ideal for racing exactly?
They're maximizing torque and horsepower at all rpm points. Advancing cam timing at lower rpm and retarding at high rpm. The factory cam timing is designed for maximum fuel economy at low load.
interesting. I always thought that's what having the more progressive timing in the standard tune did.
is this only useful when boosted or does na respond the same?
