Haywards itb on k24 eg. Will it fit under the hood???

[TODA AU]

Thanks for the info guys, Much appreciated. So pretty much for it run at optimal level it needs an airbox. And if im not willing to cut my bonnet then pretty much forget about it.

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.

Didn't JDMYard EGK20A have to cut a big hole in the bonnet to clear ITB's?

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)
