Correct cam timing and decent ECU mapping for start
lolTbh I am impressed and staggered to see it making that power at 7700rpm!! If that is true then potentially you could cut down on a few items. I would have thought you'd be needing 8500-9000rpm.
Assuming that peek at 7700rpm and a rev limit ~8000rpm then in addition to the ITB's: It'll need a big valve head, big cams, solid lifter top end (although the revs arn't monster, the ramp angles and valve lift will be), VVT delete for verniers, 8 injectors (so standalone too).
Assuming more like 8500rpm+, you would want Maxi Evo steel crank, Maxi Evo rod/piston geomertry (144mm rods, 84mm pistons), double valve springs and Ti retainers.

If that kind of power can be got around <8000rpm, I could stick a BV head, solid lifters with new cams/verniers and ITBS/standalone - probably about £5/6k mapped. First gotta crack 220bhp on the standard hydraluic/vvt setup!!

And you should take into the account that this dyno and the ones that we use are not the same. This one is as ideal as it could be for producing bhp.

good points, so we should believe the 7700rpm is correct - I am amazed though.
As for motivation, well I guess I could buy another F4R and stick it in the car and then strap my forged lump on a dyno and go mental! lol!! Realisticly though, if it makes decent power on Wednesday at RST I'll keep the car and probably stick it on a standalone at some point this year (it opens the doors to ITB's). But I don't think I could ever justify changing the top end for a solid one........although I could buy a second head and do it slowly over time..........! damn you fano!!

I believe it's more important how your car performs in the street rather than on the dyno.
There was a lot of "dyno queen" cars that looked good on paper but underperformed in the street.

Depends, but the correct interpretation is to judge the full area under the curve not just peeks. Like you say if you judge only on peek fgures like a dyno queen then yes it might be crap on the street. But equally if you don't make the goods then whats the point! Gotta be both or no point trying

Satin black wheels, but glossier than I wanted but not a full gloss. Look the same as the Renault speedline colour.
Inlet manifold turned up just now.
Website is broken hence the tapatalk images. Think my hosting provider ****ed it doing a server migration. Can't edit old posts or updated the theme php files if anyone knows wordpress/php/mysql!?

Pure Motorsport, not taken out to gasket, tbh that would be pretty damn big. Also the lower to head was just a clean really as without the head we didn't want to risk going bigger.
It's a decent tidy up and matching without going over the top. So no question it'll be an improvement without any downsides. (go too big and you might loose gas speed etc kinda thing). I need risk free mods from now on! If I was doing a head job though we could have been more aggresive for sure.
Weight of the upper manifold, please?
4580g (including 2 little black brackets on it).
