Does removing the heater core and the ac add any extra hp? i just bought an 89 gt and this guy took them off for more power i guess. ive had multiple people tell me it adds power and multiple people tell me it does nothing.

I dont know if it adds power, but it reduces weight

he also took off all the anti polution.

Unless it's a full drag car w/ a gutted interior, it's really a waste of time and effort IMO!! Sure, less weight, lower et's but what kinda power does it make? What's done to it?

i think he did take it down to telegraph and race it for some moneys, the whiper blades were off too and my temp gauge doesnt work. probably took out the thermostat. Im going to stick it all back on its just my daily driver.

For the temp guage check the ECT sensor. As far as removing that stuff the heater core probably doesnt do much if anything and the ac removal just frees up horsepower since there is less drag on the motor.

The ECT sensor has nothing to do w/ the temp gauge. It's for the ecm. The temp gauge has it's own sending unit.

From what i heard of it running today it sounded pretty stock still havent looked at it much though.

A heater core doesn't weigh much anyway

You might as well just take a big crap before you run it... that would be equivalent to the weight saved by removing the core.
