Really?? That's kinda f'd up. guess I never got close enought to a 2.2 to check it out. I don't know anyone who's actually used the Tornado, but it sure looks like a bunch of hype. Seems to me that the money could be better spent elsewhere.
I feel your pain on the one piece TB/intake piece. If you really wanted to convert over to a 2 piece uinit, so you could run a throttlebody spacer as well, you should check out www.mantapart.com If you go to "parts" and then down to "performance parts" and then pick the first motor on the list, which is the 2.2 they have some stuff for our engines that you might be interested in. It is a bit more than $60 but i think it would be more effective than those vortex things
I had a long talk to my brother-in-law who's a Phd at Exxon and does fluid flow dynamics for them on this very subject. Absolutely nothing that's installed before the throttle body other than a less restrictive filter, blower, turbo other the like will do anything for you. We've yet to finish work on it, but we even have doubts about whether an aftermarket intake pipe really does all that much. Mostly it's the filter and colder air for those kits that have the plate that separates the filter from the engine bay. But I digress.
Anyway, a throttle body spacer lenghtens the intake tract which has an effect on your power range. But don't spend extra on one of those with the "helix." That's a crock too. Only a very small fraction of the air moving through the throttle body will hit that area and mostly only during WOT. The intake design itself where you have the split into the separate intake tracts creates a vortex that would cancel out any created earlier in the intake.
OK, my $.02... Take a look at your TB... notice how it turns... even if the air spins before it gets to the TB the way that the TB is designed it will counter the spinning. Please let me know if you understand or not.
