Must say it surprises me, as breathing throught the filter goes without a restriction. Of course this is not a valid test.
I'm pretty sure that it would show up clearly if that much hp is lost with or without. As far as Bill stated, no air filter is not an option. So untill I find a suitable solution I'll have to run these or the mesh typ of screens, which are even worse as far as filtration and restriction is concerned.
With the setup I have basically 2 problems :
- hood clearance above the valve covers is not large, but just adequate to build something.
- difficult for bracing any type of air box since I would have to mount the baseplate right below the bellmouth opening. The bellmouths are aluminum and thin walled so do not offer much in load carrying capability. I also have the problem that the stacks are mounted with 4 screws to the TB's and I need to be able to access them at all times. Another reason why welding a baseplate to the stacks (if at all possible) is virtually impossible. I personally think I would need to attach the box to the valve cover in someway (drilling (leaks ???) or epoxying a piece of metal or alu to it)
- I have no place in front of the radiator to mount a suitable sized regular filter (couple of reasons for this are : hood bends in with the tip just in front of the rad, retractable head lights, bumper bracing). The only option would be cowl induction, which is a slight possibility because I use a high rise L88 type hood on the car.
So based on all the foregoing I would need to fab an air filter box which draws air from the cowl and run 2 flexibles over the top of the engine to the front and make a U turn to enter any type of air box.
Then I'm left with the airbox over the stacks which is the most difficult issue. I do not think I can mount an airbox off the stack bellmouths. Personally I'm thinkint I might need some extensions either under the stacks or under the throttle bodies.
The throttle bodies have a weber dcoe style mount pattern, so it's a possibility to move the stacks and TB's further away from the manifold in order to have enough clearance to mount a base plate to the TB's. Without trying, it looks as if I'm going to run into underhood problems.
An extension of some sort (either under the TB's or under the stacks) would be better if it would be curved so that the stacks end up upright. An air box would then end up right under the bulge.
The problem however is finding a suitable extension. I'm unsure if a DCOE 50 mm curved extension exists and if under the TB's I would have to fab it up.
