Not with the Spitfire II which is what Kurfurst is talking about. This has a Merlin XII engine designed for 100 only.
I am not sure why Kurfurst agreed with you in the subsequent post unless he forgot which aircraft he was talking about

I agree, I don't have a problem with that, but it's the clearance to use it I'm talking about.
When I was 18 I didn't have clearance to take my engine in my Ford Fiesta 1300S into the red all of the time but when my six was occupied by another kid in an Escort or Golf I pulled the tit and away we went down those country roads like dickheads. After a while I blew the camshaft out of the side of the block, I'm pretty sure Ford didn't recommend this.
I should scan a photo of my heap of crap, I would've killed for one of these.
