bonnet clearance

guy_27

quick questions i am hoping someone here will have the answer to.

what will be the bonnet clearance with a harrop supercharger on a mk4 astra?

I am hoping for an answer of greater than 1inch.

I know the Harrop is bigger than the GM version and clearance is tight, so the Harrop might be a tight fit notsure.gif

but Harrop is the future 8)

cheers vocky,

you wouldn't happen to know the clearance with the gm charger.

Mark Watts at Courtenay can give you an idea. He has the Astra G with an Eaton M62. He retains the original MAP sensor position on top the charger with no clearance issues. I however have had to raise my bonnet by 5mm, remove the sound proofing and reposition to MAP sensor and then flush off and block the original mount point. The Harrop would only fit under a Vectra B bonnet with extensive modification to the bonnet itself.

I think the the Harrop on the Astra will be very close but I'm sure Mark would
be able to point you in the right direction. It may be a case of some minor mods like carried out on my Eaton.
