What Power a 3.9 v8
Discussion
just a simple ( if there is one ) question a V8 3.9 based on a Rover V8 that came out of a Marcos
has just been put in to my Mg ( sorry ) it is a great engine and pulls like a train but i was wondering if anyone knew what
type of power bhp & Torque it could be putting out.
I think it is out of a newish car as it has only covered 15K Aparently and it would look like that is the case as it is Mint.
thanks for any advice ................. ill now sneak of back to the Mg section

That's a 190bhp engine as standard in the Marcos - I assume it's on Hotwire EFI? Sometimes they quote 205bhp and if you have good compression on a minty engine, why not?
220-230bhp is reachable cheaply (it's all relative) with better plugs and leads (Magnecor), a short cone-type K&N filter and a decent chip. A little bit more money sees shorter throttle trumpets, after that it's silly money time. RPi (RIP) are probably the people for this, just don't let them build you a whole engine (long story). It will pull better and you will get better throttle response too. That standard engine just can't breathe.
The jury is still out on improved fuel ecomonmy...

I sincerely hope your 220bhp was at the wheels, not the flywheel! A standard 4.6 in a Rangie will make 225bhp at the flywheel with nothing done to it! Anything breathed upon should be making 270bhp.
Very heavy breathing will make 340bhp, I don't think there is much more to be had reliably.
