Cam duration of 256 Kent AST1604 kit.
That was more of a statement than a question you fool.

I'm with JR changing pistions whether its pocketing or going for high comps will make a difference.
However in Daimo's deffence production variations and the fact the engine wasn't blueprinted could be a factor in the power output.
Lee Mitchell has a neighbour had a Nova xe with just a bill blydenstein head with serious headowrk made 175-180 bhp on several rollers....such a freak of an engine!

I can beleive that Fad, Bill Blydenstein is a head god for a start.
Also VXR, is that flywheel power or wheel power.

256 cams don't need new pistons.
If you had said 264 degrees, i'd have agreed, but 256 cams are designed to go with standard pistons, considered "fast road" cams. New pistons would be a waste of money.
But then again, I know nothing, so go ahead and spend all that money for no reason.

Except he passed away a few years ago and the business has been carried on.
Flywheel power.
What, you actually are asking that too, you think a 1.6 NA 16v engine without larger modifications would run 161bhp at the wheels

If you well were clued up on these engines you would know the weakest point on the engine I am using is the pistons and rod as it is a low out put engine for a start, the reason the rods are weak is because they are sintered steel.

Depends if its had £3k's worth of tuning chucked at it and its in a stripped out shell, esp vs a 2.0  
tbh, Donnas engine was about as quick as yours was, but with all that weight in it. Yours ran much less power, but hardly any weight. D5 was "a little plump" would you not say.
Don't forget it went bang when she clipped 7500rpm (no rod bolts, her own fault!!!!) chasing me and a VX220 NA up wainscott bypass on the way to Trax
Sounded very "scooby" like running on 3

VXR, you really don't know what you are talking about mate lol I'm not saying I know it all before you start, but you are taking what I say and trying to make me look like a fool, when really its you, you've already been proved wrong on a few things here.
Also, maybe I don't need pocketed pistons, but I have them now and they are high compression which is good as has been discussed.

I am, and no the pistons are not the weakest point on the engine.
I've known people to have the standard pistons pocketted, (in fact, im sure Lee's were standards that were pocketted JR/Fad), and have no problems.
The pistons arn't the weak point, its the connections that are. When your hitting 8000rpm in these engines, then you want stronger pistons and start to upgrade other parts.
When your hitting 10,000rpm, its fundimentally, a new engine internally.

You don't need them at 7500rpm no is what your saying?
Anyway, you bought them with pockets already in them didn't you? (the engine I mean).

I didn't buy them for the pockets I bought them for the security that I know they wont break and as they're high compression.
Also its easier to change the cams and inlet system than it is to strip and rebuild a whole engine.

Standard ones won't break though.
so your doing pistons, but not the rod bolts, the cheap and weak part?
JR, remember Don Fulfords Manztel engine? That ran 264 cams and ran 174bhp also using the Lexmaul ex mani, and manztel box, increased rev limit etc. Also had some headwork done.
He was MR Vauxhall. I never doubted his engine.
Before the cams and rebuild, thats yet another engine that ran the 150's on a C16 engine.
Still, all rubbish
