January 17, 2003on my truck the air is drawn through the fender by an oval shaped funnel. It is throttled then taken away by a 2.5" roughly pipe. My question is the funnel neck extends into the funnel and is tapered to about 2 inch. can i cut off this excess neck reveling a less disturbed path and a wider intake path????

January 17, 2003Sure....the sound level of the intake will go up slightly but it should help a little...or just run an open element filter like I do...a 9" Edelbrock chrome filter
January 17, 2003Yeah I run an Open Element Filter, EddelBrock Chrome, and K&N 14x5 Air Filter....
January 18, 2003Your better off to run a good filter in a closed air cleaner with a better snorkel without the baffle. just an ordinary open element air cleaner draws all air from under the hood which can be 200+ degrees. cool air makes more power.
January 18, 2003Yeah, I see what yo are saying IHMAN, about the closed box and snorkle deal, but a open element like I am running with the Dual Cowl Induction Hood I got on my Rig, Flow`s Good Cold Air from the Windsheild, as we all know Cowl hood`s are the best for racing,or for good street car`s, that`s all we use on our Pro. St. Car`s is a Cowl, and also on the Track Car`s too... When I installed the Dual Cowl Hood on my Truck my Water Temp. Dropped 20" Degree`s....

January 19, 2003I think we argued the hot air charge point to death in another post.....it`s a personal choice what you run

Blower applications will differ, especially with positive displacement blowers, since the restriction equates to little else other than pumping losses.
The only time underhood temps are significantly higher than outside temps is at very low speeds. Once again people that actually tested this found that underhood temps where on average only 5-10 degrees above ambient once the vehicle was moving.
If a closed cool air system has equal restriction but cooler air in theory it can make more power, but this is rarely the case. By nature a closed system tends to have less filtering area and higher restriction.
A just as often reference that is incorrect applies to Ram Air Setups. Most factory setups provide very little pressure over ambient. People fabricate massive ram air systems and in effect cause a lean mixture and screwed up A/F ratios at higher speeds. Race applications are tuned to keep A/F ratios safe at maximum pressure.
