Default modify hood cost..

Anybody have an idea how much it would cost to punch 2, approx. 12 inch square holes in a hood ( exhaust 'scoops)....and paint the hood.

Do you already have the scoops that you want to install in the holes cut in your hood???

Am I correct...12" x 12" holes?

That is quite a bit of material being taken out of the hood. SO it may require some reinforcements to be installed...unless your scoops are stout enough to compensate for the missing material.....and their location does not cut through the inner structure Because the hood is already quite flimsy and can flex quite a bit.

If you have the scoops....what are they made of???? And depending on theri design for installation. They may get painted and attached to you hood and the hood would not require painting....once again...depending on the condition of your paint on your hood now.

What are you planning on doing with the underhood liner???

If you paint your hood...then the tops of your fenders may not shine as well as the freshly painted and cleared hood.

Thanx for the comeback DUB.

I have an ACI hi-rise hood.( see avatar) There are no scoops involved. I plan on cutting 2 holes, approximately the shape of a bell curve ( less curvey, more parabolic) about 4 inches down from the windshield and about 4 inches in from the side. There will be no scoops but a stainless steel 'grate' covering the holes from the bottom. The actual size of the hole would be 10 inches at widest point ( the base) and 7 inches 'high'.

The location will cut, somewhat, into the hood bracing, and reinforcement of some type will very likely have to be done.

The ACI hood has no underhood liner.

I was quoted around 1500 for the work and this seemed high. I'm trying to get a feel
if the price is fair.

I never thought of the hood/fender paint not matching.

Yeah...I think $1500 is kinda high also. I did not know what type of hood you had...so i was going off of a stock hood.

What do you plan on having be an edging material so you can not see the thickness of the hood when cut? It could end up looking rough ...and not a clean, consistant thickness of an edge as you may think. You should have something there to also aid in strenghtening the hood around the opening to take away any possible chance of a crack starting in a corner where it was cut....due to the hood flexing.

Not knowing if this car is driven in all types of weather conditions. You may need to consider rain. If enough water gets through these grilles...even when you wash it...and gets down on parts of your engine that are not designed to get wet...you may have another issue. You may need to install a baffle with these grilles or a shield to cover these electrical parts from getting wet.

There are some simple tricks to strengthing up the underside of the hood in the area of you cut-outs. It does require adding fiberglass mat and resin. And depending on your desired outcome...looking at it from the underside...may require a bit of finesse so it does look like a "hack-job" when completed. Seems like you have an interesing "concept" beginning to take shape. Hopefully you can find someone in your area that can get it done for you at a reasonable cost.

I am encountering some resistence by several body shops RE: locating the 'scoops' where I want, due to having to cut/remove the underhood bracing, where the 'scoops' are to be located. As you said, it appears this underhood bracing is important.

I guess my question is, in your opinion, can the 'scoops be located where I want and not compromize the integrity of the hood ? I could put the 'scoops' on the hood where the bracing would not be touched, however, that is not what I want.

ANYTHING can be done. It will all depend on where you want them and how much of the inner structure is going to be effected. GOOD photo's of the underside of your hood along with the a "mock-up" piece of cardboard to simulate the scoops would be a great help. If you can not post photo's...them PM me with your e-mail and I will send you my e-mail so you can send them to it.
