where to buy a 5 litre engine?
Discussion
Rule of thumb daz works like this we live at around 14.2psi from the srrounding atmosphere so basicaly you have that pressure being forced into your engine without any help so if your engine produces 200bhp under these circumstances if you blow it at another atmosphere or 14.2psi it will double the horse power to 400bhp so half a bar or atmosphere would give you 300bhp less mechanical losses but thats how forced induction works harder you blow up go the losses so its not open ended

or for Daz the answer is yes. Just 4lb of boost should give you another 80 bhp or thereabouts.John
OP, useful information about the various RV8 lumps in thread (link) below, written by Rob Robertson in 2013...

What about the pistons and V8D Stealth can .?
Daz I have the turbo from eann on my high compression 4.6. Thats a 10/1 comp engine. I run around 4 psi and the engine is fine. I went from 280 (with cat) bhp to 380. Torque is around 470 :OWith the SC you get around the same numbers but the torque curve will be more linear. With the turbo you have full torque from 3000... dangerous in the wet

Great numbers Ole, and totally with you on the 'dangerous in the wet' comment....
You need to be a driving God to handle 380bhp and 470ft/lbs in something that weighs less than a Ford Fiesta though...
