The problem comes around 360bhp, and is where 99% of tuners come into MAJOR problems as essentially thats the reliable max on a cvh engine. However it is possible to go much further in the power stakes, but at a pretty extreme price! Itd also worth pointing out that it took us 15 years of modifiying these engines to develop a package that works, so it's simply not something you can stumble on by buying random parts off t'interweb and fleabay!
Our top spec CVH engines (i.e. beyond 400bhp) cost from 15K.
fare play for the work that youve done with these engines and ive seen them produce the power etc and do some good top speeds etc , but to get that sort of power just makes the engine unreliable and didnt ollies block split in half because of the 40psi you were running to get the 400 bhp ? . i agree that you simply cant buy bits here and there but if you cant make ollies engine reliable what chance have you got with a customers engine? and £15k is alot of money for a engine.
what does the £15k buy is it something like this
block with niksal liners £1000
forge pistons £700
h beam rods £500
custom crank £1000
race bearings £300
arp bolts throughout £400
cosmetic gaskets throughout £300
custom big valve head £1500
something like a jenvey plenum £1500
70mm throttle body £300
custom tubular exhaust manifold £1000
external wastegate £300
turbo (gt35 or similar) £1200
injectors x8 £500
dry sump system and fittings £2000
fpr £200
standalone management £700
wiring harness £500
engine dyno £1000
total £14900
thats what i would expect and if any of the above was missing off the list i wouldnt spend a penny because i think this is whats needed to build a reliable big bhp engine wether it be cvh , zetec etc
can i ask is it 40+ psi you run on your big spec engines
it will be good to see thou so carry on and whens the d day for it to run?
cheers paul
