butterfly valve delete

[Shadow1]

can you take out the butterfly valves in the intake manifold and drive with out any problems? would you get any performance gains from it?

[sulimed]

more than likely would lose low end TQ.

[Shadow1]

well then. i think one time i saw on someones members ride thread that they had deleted the butterfly valves

on the f22a6 they work for low end torgue and then when your get to 3500 or 4500 they open up and you gain top end horsepower.

talk to cisco, hes got his h23 mani all bored out and i believe hes got the butterflies removed

I got butterfly delete on my h22 and if i'm not mistaken you lose low end a bit but gain top end a bit

[Shadow1]

well id rather get that mid range power instead. there are too many things out there to raise the top and low end power.

i just wanted to save on the getting the ECU and wiring. oh well. lol

1. Low end will be gone.
2. Gas mileage will suffer a bit.
3. You dont have to wire it you can just hook it up to a vacuum source on the intake manifold. They will open a lil soone raround 4700 thouigh. Thats how I have mine setup because my h22a didnt come with a black box.
4. I would think the delete benefits the turbo people a bit but I could be wrong.

well i have an f22a1. i planned on getting an h23 or f22a6 IM b/c i know when i had my JDM f22a6 it had the dual runner IM. i want to feel that power again. lol.

yeah but who cars about low end.. when racing your all up in the upper r's, am i right?

[NAiL05]

I care about low end. Picture this your going up a small hill in 5th gear doing about 60. YOu need more power right but you feel lazy to shift out of fifth. Floor it and see where you go =D. Thats what happened when I had my exhaust removed from the cat back =D Loud as fuck and no low end.

[DraZtiK]

if your too lazy to drop it a gear you shouldn't be driving a manual, haha.

Downshifting wastes gas. And when you have an open exhaust I doubt you want to downshift.

i have removed the secondaries from my h22 mani the engine has yet to be swapped but yes you will lose low end tq and gas mileage (who fucking cares its a swap for christs sake) your top end will be slightly improved in an N/A setup and will work great for a boosted setup. i have pics of this deletion here:
