• The site migration is complete! Hopefully everything transferred properly from the multiple decades old software we were using before. If you notice any issues please let me know, thanks! Also, I'm still working on things like chatbox, etc so hopefully those will be working in the next week or two.

pulley debates

mechguy said:
Apology in advance for thread jacking. My question is of somewhat a similar nature:

Can a human being notice a difference between a 3.4" and a 3.5" pulley? Provided that the car is appropriately tuned and possesses the mods of headers, intake, plugs and thermostat. Maybe said human being is better off with the 3.5 for peace of mind....


EDIT: I can perform calculations given a compressor curve, to determine the pressure difference. But I am more interested in a "seat of the pants" interpretation.

You'll probably feel more difference in the tune, depending on whose doing it.
