What do you get more HP out of? - Honda Prelude Forum

i have read a couple of post from different people that have put a S2000 throttle body on their 5th gen preludes. my cousin swears that you get more HP out of putting a throttle spacer on then putting a S2000 throttle body on. i dont know much about throttle spacers so im a lil ignorant. i just dont see how you dont get more HP from the S2000 throttle body. it is a 80mm throttle and the OEM throttle for my car is only 65mm. someone please help me.

The larger opening allows for more airflow. The spacer creates higher air velocity because it has a longer time to accelerate

You're mistaken on both sizes of TBs. The stock USDM Prelude has a 60mm TB and the S2000 is 62mm.

wow really. i read on another honda forum that the TB sizes were 65mm and 80mm. are you sure?

yes Kronn is or he would not have said so.

the throttle body spacer also increases the total volume of the intake manifold. (unknown to most, you want your intake manifold volume to be bigger than that of your displacement.)

Kronn's mom has a tattoo that says son.
