MG ZR: Cams & Maps

[lolsteve]

Everything was standard bar the intake when it pulled 120 (at the wheels) and had new spark plugs and leads.
Bluey also had the same induction kit (without cold air feed) when it went on the rollers back in the day, so perhaps a pattern is emerging

Been doing some more reading about the MGF/TF and it seems the biggest improvements were coming from the upgraded airbox from the 143 engine to the 160. Which was larger and featured two intakes instead of one. If we assume the un-feeded cone filter is acting on a similar level to the 143 engines airbox and that engines are very picky in regards to induction then perhaps..maybe...i hope.. this is the cause of some of the losses.
As a sidenote the ZR 160 box only has one intake.

Engine has also got a small misfire and threw up a code the other night for cylinder 2 (P0302). Checked plug gaps and they're about the 1mm region and leads all pushed in. There's been a odd ticking noise at about 2k+ at certain throttle positions, reminded me of the hdi injector tick so trying some BP fuel instead of tescos and a bottle of Redex (only £2 at halfords) to see if that helps out in anyway

Piggy I am hoping I can get this running the way it should as I've started to put investment into this now (coilovers, cams etc) so would like some payoff rather than just more disappointment with an empty wallet
