Bonnet scoop for SP20

[TDK]

I am looking at buying a bonnet scoop for my SP20. It's going to look a bit like the WRX scoop but a bit longer in length. My question is should i just have the hole cut on the bonnet and have the scoop installed or should i have the scoop moulded to the bonnet and then have the bonnet resprayed.

What are the pros/cons for both of these methods.

[dfvadr]

either way u need a hole in ur bonet or the wind travelling in the scoop will cause a lot off presure in the scoop an in time the skin off ur bonnet will seperate from the frame

[Dogo]

LOL i'd hope there would a hole there.

i think the question is whether to just bolt-on a scoop to the bonnet, or to mould the scoop as part of the bonnet. with fibreglass or whatever.

hmmm

a scoop moulded as part of the bonnet would look heaps better in my opinion. my suggestion would be to cut the hole, bolt the scoop on. and smooth the join with resin/bog. then re-spray.

just watch out that the smooth seam wont crack. perhaps a panel beater can advise u on whats good to use.


what do u do abt water etc getting in through the scoop ? better be careful thats not going to hit any wiring etc.

also ... what do u plan for this to do ? are u going to run ur air intake to the new bonnet opening ?

[dfvadr]

u dont use bolts these days , there is black glue type stuff called sticker flex 3 different stages available u can get it from a car paint supplier an it about $25 for a gun cartridge size man this stuff can hold anything

You should have enough air being forced into the engine bay without an extra scoop. For practial reasons an A9X style reverse scoop would be better as it would draw the hot air out and away from the engine.
If you are only interested in looks then what I've said should be ignored.

I'm not too worried about the air getting in. I'm only interested in getting the scoop for looks. I got quoted $420 to have a sccop painted+fitted (including hole). They also quoted me $940 to have it painted+fiited AND moulded to the bonnet.

[dfvadr]

$420 sounds a bit steep to me ie a wrx series 2 scoop is about 100 depending where u get it paint around 100 lets say 3 hours labour at 50 350 should be a dear quote ill have sum pics up next few days of my car so you can check out my set up mine is a bit wild though u mite just want a plane set up im shaw i can help u get 1 fitted cheaper

I really like the style of the celica scoop... it's not a look at me type scoop, but looks to be effective enough... IMHO looks more classy than the wrx style scoops.

Have you guys received/installed your rear tail lights from the US?

cheers,
Bill

[dfvadr]

yes i have the clear lights in mine ill have pics of the car done tommorrow so an post them up next week monday or tuesday

i think the scoop of the Ford Cougar Eibach would look great on an SP20...

*sighs* What it is about WRX scoops?

Surely they're like an asshole? Everybody has one?

Mazda does have some bonnet vents in its heritage, use something derived from those and be an individual.

Car modding is becoming very sheepish these days!

[Rupewrecht]

i agree!

if i ever got one, it'd be the inverted style - something like this (shown from the drivers view)

or this

looks a bit more purposeful and original, as after all you see Excels with WRX scoops tacked on...

but thats just my opinion :)

Considering that Subaru use the bonnet scoop because the Liberty RS and original Impresa didn't have space for an FMIC on the production line.
I'd rather see an RX7 series IV/V scoop if airflow to an intercooler was needed or a 1980 Pontiac Trans Am type reverse scoop to remove hot air.

The Wings West CF bonnet has a EVO6 style scoop and IMO looks HORN!!

Have been looking at doing a RacingX EVO scoop, fit, mould, paint bonnet black.

Can get it done all up for $450 with Madhatter who does good work, including supply of scoop (from elsewhere).....

Something to think upon....

i figure that everyone uses a wrx scoop because they look smart an there not bulky
an in regards to ur comment cosmo about the a9x reverse scoop that was a wind deflector design to send the wind along the sides of the bonnet to keep it down an the raised bit sent the wind over the windsheild ie less drag in racing witch the car was built for an that was old technoledgy
these days they relize the more cold air that gets in the cooler the motor so there for better performance an no poor deternation in the cylinders
so too look rite into scoop designs each has its own purpose
just thought i mite share that info i saw with u guys

Or maybe the flow of air over the scoop draws hot air away from the engine and over the car (not under it, ground effects, as you know). The only cars that duct extra cold air under the hood use it for intercoolers like WRX and Rx-7 IV and V. Vehicles with FMIC don't. Check the Nissan GTRs, Mitsubishi Evos, 323 GTR, XR Falcons and many more........

that was phisiclly impossible the a9x off the show room floor didn't have a hole in the bonnet
as mentioned earlier it was down force and deflection as cars in thoughs days didn't have the areo dynamics we have today they were more like house bricks an to get speed out off them an keep traction they came up with the front spioler scoop an bobtail flares kept the air out off the wheel arches ie overall kits less drag more speed

[Critter]

The A9X scoop is a different principal again.
With housebrick shaped cars like an A9X, the scoop faces the wrong way and collects from the base of the windscreen because that is a low pressure area and it therefore sucks air into the scoop from that area, rather than blowing it in high-pressure style as in a forward-facing scoop.

Didn't have an engine either but did quite well on the track. I wasn't suggesting using the actual scoop but that style to remove hot air from the engine bay.
As I initally said, if you're doing it for looks then ignore me!!!
