If you’re going to spend the money on ITB & use them to full effect,
Honestly, It’s a waste of time if you just fit them for the sake of it.
For the money invested it makes no sense to go about things half arsed.
Though the Haywards may not have an air box readily available, a TWM or Jenvy one might work, failing that there’s no reason one could not be produced.
Further, there are other ITB’s for similar money on the market that can be made to clear & have a box fitted.
Though space will be a premium in an EG, ITB’s & an airbox can be done.

You’re right,
A bit of background on that one.
On the dyno, the trumpets were shielded from direct airflow & the output was pretty good.
On the drag strip however, in an attempt to get more air in, the hood was bashed down exposing the trumpets.
The buffeting air flow over the trumpets net effect was a drop in MPH (or HP loss)
Contrary to popular belief, forward facing exposed trumpets is not such a good thing..
If they're going to be left open, they'll work a lot better in a tray, box or bucket.
Smooth linear airflow is your friend.
Though air filters are optional, they’re still a good idea (insurance)

Alright so it can be done. But with alot of custom work i believe? Your right Adrian no point spending money for the sake of it.

If you got money to spend, try to get your hands onto a IPS intake manifold.

In This picture, wouldn't it be better to have the trumpets fully exposed then have it half cover by the bonnet? Is because the pic is the way it is.
They pop out dont they, How the hell would an airbox fit under the bonnet.

What do you plan on using the car for? Because the rules of whatever you plan on using the car for may prohibit anything from protruding from the bodywork of the car (eg. the All Motor class).

Well good question, i havent really figured that answer out for myself yet. This is pretty much what i have in mind. I wanna build it now for drags. I wanna try and get as much power as i can out if this engine.

My goal is 11sec's, maybe faster but i know its gonna hurt my bank balance if im thinking of 10's. I know its not easy, i've heard and heard. I dont want turbo, im sick of turbos all my mates had turbos and im over it. After im done with drags and ive reach my goal. Im gonna stick all the roll cages in and necessary track accessories and setup and tune the thing for the track.

People say you cant do both its either drag or track, But im gonna try. I hope to finish this car in 6months from now. And then the testing will begin. But right now im new to this and im doing my research so that i get this right for i what i want.

Its good to hear from other people what they think and recommend.

rofl.

As Adrian stated above, people think ITB's in the open "ready to suck in everything" is the best, but at 100km/h the pressure and turbulance stuffs everything up.
