i'd swap tb's while your in there..the added throttle response alone is worth the swap
Maybe, but it bumps me up a class (or more) for autocross. (As if I'm competitive, anyway.)

who tells the full truth in autocrossing anyways:shrug: it still has a ford part number.

I'm going to assume you meant "25 to 30%". That implies ambient-to-intake air temperature deltas of 275ºF to 330ºF. Allow me to explain.Drawing hot air cuts the power way back. Probably in the neighborhood of 205 to 30%. An open element intake drawing underhood air often suffers greatly in hot weather.
so?:shrug:Whatever. Whether I mod the TB is really not related to my question.

This seems to me to be the best way to answer these questions. It would be interesting to see the effect on measured real world performance on this question. It seems to me that turbulence generated by the filter element is alterd down stream by other parts of the intake system to include the uim/lim and the amount of stuff built up on the valves. Some turbulence in the combustion chamber seems to be necessary for complete combustion. I believe a clean filter is probably more important than its type for most of us most of the time.Now, I know a lot of people with data acquisition systems on their track and street cars (yours truly included...), and I've seen datalogs of IAT (Intake Air Temp) and underhood temps, and you might be surprised at how close to ambient temp the underhood environment is in a typical moving vehicle. Sitting on a chassis dyno just isn't the same; no quantity of dyno fans can fully replicate the environment of moving a vehicle through the air at speed.
Let's see your data.I'll still stand behind my comment about 25% to 30% reduction in power. I don't doubt your calculations, rather I think there may be more involved. The power loss is very significant.
no they wouldn't. your forgetting about NVH,noise vibration harshness.If the factory didn't have to worry about drivability issues, they'd install open element systems at the factory, wouldn't they? With less parts to the intake, they'd save money too.

Drivability covers all those things too. You'd be surprised what customers bring their cars in for and say they can't drive it like that. :crazy:no they wouldn't. your forgetting about NVH,noise vibration harshness.
Spend more money on go-fast parts - I have found a direct correlation between wallet thinness and butt-dyno accuracy and resolution.Sure, just as soon as I can figure out how to collect data from the butt dyno.
