Head banging....
Theshed - 22/3/20 at 11:18 AM

I am gradually adapting some existing bodywork for my car - creating a dirty great air scoop. I used the internal air scoop and covered it in foam/glass/filler to form an external engine cover. It is nowhere near finished yet but I sat in the car with a helmet on today....

It is a bit claustrophobic! The forward roll bar brace is about 3" from my head but the airscoop at present about 1 1/2". I can probably gain another inch or so.

Can anybody who races/track days a lot tell me the extent to which I can expect my head to bang around (750hp so a few G forces I expect).

Could you not modify a little??
Making it taller and less wide?
Also, do you expect to have passengers? if not, why donīt you put it where the passenger head would be?

I can certainly make it a bit thinner...

The difficulty is that it covers an inner airbox cover. It is a complex kevlar/carbon moulding and whilst I could chop it about I would rather not.

I would like the option of taking a passenger. There are only a couple of possible race series for this think - and it will not be competitive in either - it has become all about completing it rather than creating anything that might actually be used regularly. It is likely to be a track day toy at best

does the scoop actually achieve anything more than a big hole?

Yes...This is a 200mph car designed for ram induction.

Sorry that appeared a bit snotty...

The internal air channel is an inch or so smaller than the picture I have posted. Pictures of the internal version are in my photos. The engines are Indycar units which run flat out in circles (very strange). The airbox is very carefully designed and I am trying to accommodate that (and failing).

The LMP version which I am trying to emulate (although it was a failure) was turbocharged - it had a smaller air intake.....

You need to have a photo taken with you in the car with a helmet on. It looks like it will be a big problem but you'd need to see what it looks like in real life.

Agreed, It looks like it might need to be higher so as to be in the airflow anyway ?
