It seems to run the same whether I'm in town or on the highway. I couldn't see any benefit of my engine sucking in 150*+ air into my engine. Just noticed the negatives of it breathing the hot air coming off my engine.

Because your not running enough boost to benefit from the open cone.

Ok, I see. There comes a point where it's kind of a must have. What level of boost or pulley size would benefit switching to the open cone? From what I found doing a search would be a 3.25". Is that pretty close? Just wondering because I'm about done with my supporting mods for a 3.5" pulley. Just got my PCM back today from reptile.

anything below the typical 3.4 setup. As soon as you run meth or an intercooler run an open cone.

Thanks! I won't be going that far. My MR2 takes care of any $hit talkers and only comes out for money or a slap in the face. My GTP is just supposed to be a low 14's, high 13's if i'm lucky DD.
