    Anyone have one?
    I like the part they say when going slow on the trail the heat can escape out the top. I got peerty warn out there this summer!!
    What about rain and water?? Does the cowel alow tons of water in right on top of the air cleaner and distributor???
    Looks tuff but is it realy worth the "Look"????

    Steve, don't forget that if the hood lets hot air out through the riser, it exhausts right into the cowl vents, which are the inlets for the Blazer's ventilation system. I think that'd make the driver even hotter. FWIW, I have ridden in a car that had its hood louvered and the passenger compartment was hotter in that car due to the hot air being drawn into the ventilation system (I'd also be leary of fuel and exhaust gases entering the passenger compartment through the ventilation system).

    FWIW, US Body sells fiberglass cowl induction hoods that come with the cowl closed. I guess you cut it open and put up mesh if you want. They are expensive as all hell anyway, but they do have other cool fiberglass (and steel) parts.

    Goodmark Industries (<a target="_blank" href=http://www.goodmarkindustries.com/HomePage.html>http://www.goodmarkindustries.com/HomePage.html</a>) makes a steel cowl induction hood. It runs $450 plus shipping.

    Re: Cowl induction hood in FWheeler mag>>>???

    I bought my cowl induction hood from Goodmark. The shop that media blasted my stock hood used too much pressure or something and ruined it. I would rather have used the stock hood, but since it was ruined...now I've got plenty of room for that 20" tall air cleaner. (Not really, but there is a bunch of room.)

    Ah... they probably blasted directly with the blaster. Big panels are real succeptable to deformation if you don't keep the angle of blasting shallow.

    Sad to hear it was on a stock bodypart:(

    As soon as my truck runs, I'll let you know. I'm working on the wiring harness right now and then I have to throw the axles under it. I'm guessing I have 30-40 hours to put in before it'll be drivable.

    Re: Cowl induction hood in FWheeler mag>>>???

    I run the hood but used some thought and made it a real cowl induction hood, lowered the air inlet temp by 75 to 120 deg. when offroad not hard to do. No water gets into the intake when driving or parked. Fir is better than my 30 year old hood.

    OK, so I must be missing something.
    Real cowl induction?
    I know nothing about thease hoods. I just assumed it's a hole at the back of the hood. That allows air in/out....

    Re: Cowl induction hood in FWheeler mag>>>???

    The cowl area is a area of high pressure so when driving air will be forced in through the cowl in the hood. On cars with factory cowl induction the air cleaner is sealed to the underside of the hood so that all the pressure in the cowl area gets into the motor

    I run a TPI so I just inclosed the hood front to back between the stifeners and used a 4 inch rubber elbow that points the air intake strate up sandwhiched an airfilter in between the bottom of the hood and the inclosement. The hood as to be closed for it to work, when the hoos is open the airfilter is atill on the hood.

    Do you have to get weaker hood springs when you go to fiberglass? I thought I heard something like that sometime.

    I haven't heard that yet. I guess it's better to find out now rather than the hard way later. I'll do some checking around before I put it on.
