ok, i know a few people on here have made functional iroc louvers, which i wanna do sometime or another. but anyhow i was wondering if there was a way to turn around the louvers so it would great more of an ram air effect of cold air blowing directly to the engine. or if you could do that idea and add a rubber tube with a filter directly to the TB if you had map. Thanks.

also does anyone have an idea of how to remove underhood heat other then the rubber seal, underhood liner, and fuctional louvers?

 

anyone?

 

Header wrap, to reduce heat

 

Yep that would help. One thing I noticed for me though was with my Daytona hood. Underhood temps really dropped. Before with the stock hood opening the hood will introduce you to some nice heat waves. Last time I took out the Cam opening the hood and even the open element was warm and not as hot as before. With the fans going it really pushed hot air through the back opening alot. I really think just the vented louvers would help. If not getting a better fan.

Thats one thing that confuses me, isnt it supposed to suck in air or vent out? Cowl hoods that is.

 

At a standstill and low speeds, cowls let air escape.

At higher speeds however (Not sure exactly what speed, but it's not too fast), the air hitting the base of the windshield forms a high pressure zone, and it actually begins to suck air in through the cowl.

 

as soon as you get up to about 10-15 mph, the cowl reverses flow, like primetime1 said.
at around 20mph or so, it is venting air into the engine compartment as opposed to letting heat out.


i had honestly never thought of hooking a tube to the louvers and using it as an intake.
i can forsee problems with water and other stuff getting in however.

 

ok this will sound crazy but here i go, what would you get if you were to say attach a tube from the opening of a ram air/open hood and was to cut a hole right into the tpi plenum (if you had tpi) and put the tube in there and seal the cut area around the tube so air would kinda by pass the runners and make its way thru the engine itself easier? crazy i know and its probaly worthless of the idea but i really dont see the point in actually having the restrictive long runners.

 

You need to go through some form of runners, that's what directs and divides the airflow directly to the intake valves. If I read what you're saying correctly, you would be forcing all the air into the lifter valley, which is not where the air needs to go.

What you're talking about sounds similar to using a single-plane carb manifold like this: http://www.summitracing.com/parts/EDL-2975/

But look at the 360* view, it still has runners leading to the intake valves. They just are shaped differently from TPI runners.

I can see what you're saying I think, but you can't do that with a TPI manifold. However, you CAN modify a manifold like the one in the link for fuel injection, and they're quite effective.

 

ok i see what you mean, it was just worth a shot asking though lol. so say if you were to modify a carbed manifold to an FI manifold, what would it be considered then? And would the manifold be more consentrated on more hp then torque? what does it all take to modify them and would the computer need to be reflashed and all?

Check out the stickies at the top, like "Single plane EFI manifold" and "DIY intake parts"

 

thanks, seems like some welding is involved, and i just looked at the first few posts! i think i would like more of a bolt on intake instead

 

I think I've seen some where the holes are drilled and tapped for threads for the injectors, no welding. Or you can buy that style intake with the machining already done. Just an example: http://www.summitracing.com/parts/HLY-9901-101-1/

 

yah, a already converted manifold would be more pratical. How do these have an advantage over say HSR or superram? as i belive hsr goes to about 6k rpm and same with the linked manifold. 2more questions, is the linked manifold legal, and will it require tuning?
