RR Merlin 5.4 inch bore by 6 inch stroke gives about 27 litres.
Griffon 6 inch bore by 6.5 inch stroke gives about 34 litres (or liters for Dave Gonzales).

Hey Dodgeman
2200BHP most likely to come out of the RR Griffon which was based on the R engine---25% bigger in Capacity than the Merlin but only about 5% bigger in dimensions.
I could be wrong, but its worth the ask.

Harry...Im an aircraft techo and its true in regards to ground testing as well. I saw the only working Spitfire in Aus owned and flown by Col Payne which has a Merlin taxiing for take off at the 1988 RAAF airshow in Richmond. He gave it too much throttle and it torqued the wing and prop into the ground. Also, on take off, if you didnt give it heaps of rudder when the wheels left the ground, the torque would twist you into the ground. Alot of pilots in WW2 were caught out by this...not Australian ones of course.

Dodgeman...people have been fitting oversized engines into cars since the creation of the earth...but the question is will the chassis dymanics allow the car to turn a corner at speed....thats real engineering. The Blitzen Benz was made in 1909 by Mercedes...for the land speed record of 141.37mph in 1911 . It had a 4 cylinder 21.5 litre engine in it. I redlined at 1500 rpm and had 200 HP...but the car couldnt turn a corner.
I think you should have the smallest engine to start with ie A-series and work on the chassis and handling dynamics first. Once the chassis outclasses the power and the drivers up to it...then think extra HP/cubes

rb20 is out of a r32 gtst skyline rb30 is out of vl turbo... the rb20det if u are willing 2 go 2 this extra trouble 2 put a rb20 in why not try and put a rb25det? lot more power

Hmm, ya caught me standby mode. I forgot what I was trying to instigate. Oh well, lost it. Anyway, you're talking about a Holden motor, right?

well at the risk of taking more bait...
low power? in standard R32 trim they move 1380kg of car to mid 14 sec quarters, and have easy potential to 260kw+ on the std turbo and injectors without opening anything up - just bolt ons.

Yeah, an RB20 makes a lot of sense: all the extra work to make a low power motor fit iin exchange for having something you don't see very often.

you are a picky bastard, aren't ya? what's a several hundred bhp between friends?

hey, you might know if this is true. A friend who was a RAAF aircraft tech, told me that when servicing those old merlin engined fighters, they couldn't open up full throttle on the ground or the torque reaction would tip the plane over till the wing tip touched the ground - is that true? And if so, what the hell would happen to the poor old chev? anyone got any training wheels...

Thanks for the tip. If i can find the book, i will buy it as i am a strong aviation buff. Beukeleow's book barn is not far away, so i will check it out.

By the way, if you have any leads on stuff for a Boomerang fighter, we would be glad to hear of it as a friend is attempting a full resto on A46-158, a CA13 fighter. Much of the airframe is now complete.
