MG ZR: Cams & Maps

[procta]

Have you been able to find out what other rover 1.8 vvc ACTUALLY make bhp wise??

I know some manufacturer bhps are a bit optimistic

then theres factoring loss of bhp due to millage/wear

It's tricky trying to get information from a rover forum but from what I can find though a few people in 2008/9 did 160 rolling roads.
one with a backbox and open induction kit got 159bhp
another with janspeed backbox, mid section, sports cat, 4-2-1 jan manifold plus open cone got 177bhp atf
the final one from 2008 was just a backbox and got 159 atf

So it doesn't seem like rover were far off with the figures.
but would I really be down 20bhp from wear and tear on a 64k engine?

the older vvc units, are 143 bhp. mine is a "160" block with the ealier engine managment system etc, as its better system than the later one, for taking the mods wise.
i did have both systems, but i wont clog up steves thread with my experince.

Mems 2? I thought mems3 would be better due to a couple more sensors and remap ability?

no not really, the mems3 is more hot on emissons, compaired to the mems2 system. I know the mems2 system is a better injection system, well injectors are.
also the mems 2 system responses better to breathing and exhaust mods than the later system you have, proberly why some complain about de catting a mems3 car doesn't run well. mine seems to pull really hard, as that's using the rover metro gti Decat system, ( car is on a J plater)
