Im building my cosworth engine to 400+hp,7.2.1 compression T4,mildly ported head,pocketed pistons, and am stuck on what cam or cams to get. Can anyone educate me a bit or suggest some suitable cams.

 

Hi,

General reply are BD14 inlet and stock exhaust camshafts.
(that's spec of my next engine)

Regards.

Cheers mate,been looking through mag features and bd14 inlet seems to be the choice for 400hp.

 

Hi,

I have a BD14 Cosworth inlet camshaft.
Is somebody able to confirm (or not) correct timing for BD14 ?

I founded :
Inlet Timing BD14 : 16° / 65°
inlet duration 261° (16 + 180 + 65)
Maximum lift at 114,5° (261°/2 -16°)

Is it OK ?
Is exist other timing recomandations ?

Thanks for help.

Claude

 

Lee,

I'd stick with a Standard Exhaust cam and maybe a BD14 inlet..

I've got NMS Custom cams in my saff, but i'm changing back to standard Exhaust soon..

 

depends WHERE you want the power tbh! standard cams can deliver you 400 bhp!

 

Im thinking of keeping the standard exhaust and goin for the bd14 inlet.Iv got pocketed pistons is there any head mods i need? It says in burton catalogue a spacer is needed? cheers all for the help.
