Cowl Induction? - Toyota Nation Forum : Toyota Car and Truck Forums

So, being raised around muscle cars mostly,I came across an idea that I figure I would run by some people who know these cars better than I do. Cowl induction? I was contemplating fabbing a small cowl scoop over my carb and maybe swiss-cheesing the filter cover. Any comments/remarks would be much appreciated

Just find a hood from a JDM Trueno GTZ... you're a little late as someone was selling a hood with the scoop and the JDM Trueno front bumper to go along, sold as far as I know.

Comments:

- you'll run a little leaner. I don't know how much or what effect it will have.

- I suspect your intake temps will go up

- It'll look cool but people will think you have a fast car when you really don't.

- Paint trays make great ghetto hood scoops. So far nobody has taken my advice on this but maybe you'll be the first?

I guess I could bolt one down. Simple method lol, but I want something simple, not to look cool or anything. Maybe just keep it reeeeal low. Though I think for proper cowl induction ( unlike that trueno hood there) it needs to be fairly tall. I'll do a bit more research, but I like the paint tray idea. Good thinking.

Hooray for someone finally thinking my paint tray idea is good.

I have seen hood scoops for the Toyota Starlet Turbo, on E-Bay. I know several people have put them on Paseos and Tercels. They are a bit smaller than the Trueno scoop, but seem to be more available.

I wouldnt bother... Just encase the carb and stick a turbocharger there.... same effort really....

daemonside · 04-15-2009, 09:59 PM

I was lead to believe it was impossible to turbo a carb'd engine. With all the downpipes and the turbo itself and the work, it'd be more costly by far. Paint tray: 2$ / turbo w/ manifold etc: 2k& up...or am I wrong?

Ghostyman · 04-15-2009, 10:04 PM

You're right about the cost. Turboing a carb is tougher than with EFI. It could probably be done on the cheap for about $1,000 but I don't think it's worth it. The paint tray on the other hand is pure gold.

daemonside · 04-15-2009, 10:06 PM

Never mind. You can...And it's actually very easy compared to fuel injection. I still don't think I'm going to do it. Maybe someday down the road eh?

daemonside · 04-15-2009, 10:08 PM

With the tray though, there's still the issue of possibly running "thin" as you said. How would I correct that? Or would it just not really effect me? If and probably when I do this I'll post some pictures.

Damn, I just lost a nice detailed response I wrote up... so instead of retyping it, you get the Cliff notes:

You'll run a little leaner because of the reduced restriction on the intake (assuming you put a filter directly over the carb). I don't know how much leaner. I doubt it will be much but if you start to backfire, just adjust the carb to run a little richer.

I'm mostly curious to see if the IATs go up or down. I suspect they'll go slightly up since you'll be getting more heat from the engine bay.

Once I start painting my car, I'm planning on doing this myself. I figure all you need is a paint tray, a sawzall, some rivets, and a bad attitude.

I'll give you $5 if you do this and go up to some STI guys talking shit about their scoops lololol

I'll let you know when you owe me $5. I'll make it worthwhile... I'll roll up in my raised Corolla with off-road tires, homemade rally lights, paint tray scoop, and the roof-mounted PA blasting 'La Cucharacha'...

I'm one good launch away from a high 17 second quarter mile. I can already hear STI owners shaking in their boots. Real men only need two wheels for traction.
