functional hood scoop

Chris are you talking about for the OR hood or the Sport hood? Because the scoop (after looking at the pictures) kinda gets some of that reattachment air going over the hood.

Im just asking

On the TAcoma, the reattachment point is at the base of the windshield. All models, and further up on lifted ones.

i'm thinking about testing it the old school way...i'm going to tape pieces of ribbon in a grid across my whole hood, then drive at various speed. the ribbons will work like tell tales on a sail (for any sailors out there). i will then be able to see where air is freeflowing, and where there are dead spots or even vacumes...and don't worry, i'll do my best to try to get some pics. i'm pretty busy with school work, but hopefully i can get to it within the week.

I have done this. Its not as accurate as a wind tunnel. Do some research online and see what you find. Being as you are a mechanical engineering student, and have access to wind tunnels, Im supprised that you actually think the hood scoop can be made functional. Look at how low it sits on the hood, the area in which it lies, etc.

good and bad idea. we can only hope your motor doesnt hydro-lock, but i cant see it not in the heavy rain.

colinb17[OP] initial post: ↑

been wanting to do it for a while, and finally made the leap. about $30 and a couple hours of thinking later, i made the hood scoop and essentially created a "ram-air".

all it takes is a retractable hose and adapter (made by "spectre") that can be picked up at autozone (they are the blue parts in the pictures). it's made specifically for custom air intakes with weird bends. togeather they go for about $25. the other $5 was for a 4'' to 3'' adapter and some hose clamps from home depot.

a little bit of cutting and trimming later, and you have fully functional hood scoop.

it might lool a little funny in the pictures, but when you close the hood, the hose retracts to the nessicary length, and fits in the engine compartment perfectly

as for performance, right away i noticed better throttle response and acceleration...nothing huge, but enough that i could tell. i also noticed slightly better acceleration on the highway too when i was speeding up to pass cars. could be due to the fact that air in now being fed in at 70mph, or whatever speed you may be going.

i haven't driven enough yet to see if there are any mpg improvements.

and if it makes any difference, i am running the K&N drop-in filter.

Damn good idea in my opinion.

It's a step in the right direction but I'd prefer a snorkel.Just sayin'.

Lol hose looks like shitter hose for an RV

hotrod53 · Sep 2, 2014

One question... but does the drier still work without its hose? LOL

We did the exact same thing that you are doing back in the late 70's with a 1970 Olds Cutlass supreme. It ran bad under certain conditions so we disconnected it. Of course back then we didn't have computer controlled engines, we had to deal with things like carburetors, chokes, and heat risers.

Have you ever had an engine hydrolock? I have, it's not a good experience.

You guys do realize this thread is 5 years old, right?

sicki · Mar 10, 2016

is there no more posts because it hydrolocked this el nino?

@colinb17 , bringing you back.

sweet baby jebus. this is one of those threads from back in the day when there were 5000 members on TW, 285s on a Tacoma was "not possible", and plastidip didn't come in aerosol cans. it was a simpler time. we were all young, dumb, and ugly, and nobody had a clue.

So how has your mod worked out now that it's been so long?

colinb17 · Mar 11, 2016

back in the day when you had a 6'' lift and a rear mount turbo

sicki · Mar 11, 2016

@colinb17 thanks for the update. glad we are all on the same page. My reasoning for searching custom intakes last night was to find a good solution to my fiberglass fenders not having the internal thin plastic protecting dirt, sand, mud, and water kicked straight into the fender well air intake scoop....I have some ideas of my own but was obviously curious to find other ideas.
How did you go about protecting this scoop vulnerability with aftermarket fiberglass fenders?

happy friday...hope everyone is going wheeling tomorrow
