CVH Specs....
Hello all,
I am looking rebuild my EFI Block but wanting to know what specs everybody runs to achive 250bhp....
I have a st3 T3 from TT, stg 3 port and polished head, will be fitted with newman cam and solid lifters, management and injectors are to follow.
Basically i want a well built bottom end that can handle the power.
So what piston and rod combo's would you guy reconmend...?
Cheers

Yeah very good piston & rod combo for the money, you wont be disapointed. Not sure on the power my car makes as it was live mapped and not rolling road mapped, will put it on the rollers at some point though. As for management i would say go for what ever your tuner is best working with, i would stay clear of the cheap shit though mate

I brought my pistons & rods from jano @ oddkiddcreations, pretty sure im right in saying he sells them cheaper than anywhere. Theres sadly not to many good tuners around these days mate, lots of bullshit and wankers just after your money. Only one place for me!

Stock pistons are good for 300bhp and the rods around 240/250bhp if you keep the limiter as stock and don't spend your time bouncing off it.
If not then PEC and Wossner are the best value for money IMO, I ran circa 280bhp @ 32psi.
But do not go low comp!! It's a waste of time unless you want over 300bhp and will just cost you response!
The rest of your spec is spot on for 250bhp+ with good mapping.

Management i recommend OFAM...
Its good to know a standard ish engine will cope with circa 230bhp, as thats what i want... I'll knock the limiter down abit 6,300rpm as the cvh has such a massive hit of torque you don't need to rev the tits off it.
Karlos what boost level did you max your 440cc injectors out at?

Well it seems like the pistons and rods are going to be Woosner & Pec.. What other key things would you reccomend when rebuilding the car... Oil pump water pump etc... I was thinking genuine ford for these bits... Unsure on headgasket and bolts..
Any Ideas and tips...?

I put a brand new genuine pump on mine when it was rebuilt, but even with the guy at Ford giving me sympathy discount, I think it cost more than the wossner pistons!
As I'm sure everyone is about to say, standard (Payen branded I think) RST headgasket and normal stretch bolts.

What I mean by the above is my engine might of flowed enough air for 230bhp @ 19psi but yours may only flow for 200bhp at the same pressure if you see what I mean?
Oh and they were 480cc injectors mate.

Yes it was but that was on a .36/50...
To improve an engines VE as you have mentioned, headwork, cam, turbo, TB, inlet and exhaust manifolds, anything that has an effect on the way the engine takes in fresh air and then exhuasts it.
Your .48/55 will flow more at any given boost pressure than my .36/50 (it's actually the exhuast housing that changes the VE significantly in this instance), but... if for example you have a stock head then this will reduce your VE (making it harder to push the air through and raising the back pressure AKA boost pressure!) when compared to my NMS/Newman Ł1000 head.

Yeah definatley get yourself down to ford for headgasket, head bolts and oil pump. Get yourself some arp con rod bolts to go with your wossner pistons an pec rods and you've got yourself a sorted engine that will take all the power you can chuck at it. As long as a total spanner isn't building it of corse lol
