How does AC impact power? - Page 4 - Toyota GR86, 86, FR-S and Subaru BRZ Forum & Owners Community

You can test it. However modern a/c stuff is way more efficient, I'm pretty sure this a/c clutch disengages when the engine goes to 100% load as well as if it's above 90% throttle

I believe TopGear logic says it's ~2-5 hp. Doesn't matter on the road, might matter on the track.

Add a racing stripe and you'll get it back plus a few more hp.

Just my $0.02 CAD.

this car releases the A C clutch when the engine load is high so it will be identical with it on or off

i have a 91 pickup with the 3.0
on my 2nd set of head gaskets. glad they learned when they made the 3.4 at least from this mistake of a platform.

put a sticker, it will balance it out

And, I thought that when the A/C was on it also cooled the air going into the air intake thingy.. all round coolness!

Only if you modify the air intake -
