ok, last year i bought a beat up gen2 turbo II for parts. so im thinking it would be nice to get the turbo hood onto my n/a car and make it completely functional. if you are familiar with the turbo car, there is a rubber boot where the intercooler used to sit on the underside of the hood. what could i use to get air from the scoop to the stock air box set up? any ideas??

That would require a WHOLE lot of piping, and probably wouldnt be worth the effort. But thats just my opinion.

TitosToy

use the tII engine?!?!? or you can use the tII intakes with the intercooler w/o the turbo but you wont get any gains with that (if that is possible). it'll be really hard to make the scoop functional for the n/a. you can make a box inside the scoop and route it to the throttle body but then you'll have to customize the inlet.

sounds like a lot of work to me for little or no gains....

but I can say that you would be the hero of ALOT of n/a guys with TII hoods FOR SURE

Don't carb setups have the intake on top?

probably your best bet would be to fabricate some box type tubing that is actually attached to the hood. this would have to have the dimentions of your hood scoop inlet, the height and width. it's about 2" X 12"-14". this will keep your piping as low profile as possible and still give you maximum flow because of the placement of the T2 hood scoop it's a high pressure zone and will take in alot of air.

hope that helps,

yea they do. and some people here did carb their FI 7's but still, it's a minimal gain if any. hey takahashiRyosukeFC3S (say that 10x fast ) nice pic on the aerodynamics but uh..i failed college geography(sarcasm) so can you eplain to me what's going on in the pic?

if you moved the air flow meter up to the front of the throttle body and then instantly without disrupting airflow went to a sealed section from the hood scoop you'd effectively have a very short ram intake with reasonably cool air. Moving the air flow meter closer to the throttle body should help throttle response also.

TitosToy

to do that without disrupting the airflow is to use tII intakes and put the afm on top of the intake and enclose it with a box and have the opening for the scoop. but wouldnt doing that heatsoak the afm and such?


and the only reason i say tII intakes is because the n/a inlet is in the passengers side and the scoop is offcenter towards the drivers side as the inlet for the tII intakes are. i figured that would be the easiest setup if tried.

takahashiRyosukeFC3S

the picture displays high and low pressure areas. working from front to back you see if the car were in a wind tunnel you would have high pressure hitting the front air dam and bumper where the headlights are. the arrows pointing in show air movement into and through the radiator and oil cooler area. the arrows pointing out show the resistance of the bumper and hood, this is causing the airstream to be pushed away from the car slightly (high pressure area)

thats why the little vents in the headlight cover work so well, the air is hitting it rather hard and looking for a place to go. when someone installs that vent the air during forward motion rushes into that opening.

pressure decreases as the airstream moves up the hood, but again you see more high pressure at the windshield because the airstream need to be redirected again. on the roof there is a low pressure where the sunroof is on some cars. due to that low pressure the airsream will try to fill that and colide with the top of the rear hatch indicated by another higher pressure area.

I hope this all helps,

TitosToy

actually it does. i've always wondered why they've never made a cowl induction hood but from the looks of the pic there isnt and high pressure for the hood to induct from. also wouldnt be more efficient if mazda moved the hood scoop about 3-4 inches towards the front?

titos toy... do you think my car would still be n/a if i had the tII engine??? it was only the body and trans.... no engine

TitosToy

no..i was being a lil sarcatic. didnt meant to be rude just my first initial thought. sorry about that

jeff_rx7

iTrader: (1)

no thats cool. i wish it was tII, and im probly looking to buy on to replace the n/a. either that or an sr20det conversion

takahashiRyosukeFC3S

i think it's a good idea to have the air intake on the front of the bumper for maximum efficiancy like this boddy kit does. http://www.raceonusa.com/index.asp?P...ROD&ProdID=975

looks alot like the mariah front bumper. but that is a good one to have an air intake installed

i think it could work but it would have to be like a mustang shaker hood scoop. where one intake rest where stock location is and another is at the vent. but even the mustang guys say that it only really helps when your already going pretty fast (60 to 70 mph)

Using the Turbo hood scoop for intake air is a dumb idea. Why do you think everyone whats to get rid of the TMIC? Heat soak!

zbrown

all i know is that when i put my fmic on i had cooling problems..... i am thinking this is because the hood scoop was creating a high pressure zone in the engine bay and not letting air flow easily in from the front of the car

it wasnt a stock hood, it was a N/A hood with a summit scoop rivited to it with hole cut beneath (jspec swap) as soon as i turned the scoop around so the intake of it was facing back towards the window, the problem was gone...........really helped alot.... i guess kinda of like how the v-mount hood setup helps with overall cooling
