MG MGF Technical - TF 135 power gain?

How is the 135 bhp gained over the 1.8i that is fitted to the MGF? Is it through the trophy exhaust system and throttle body?

essentially, that's it - throttle body + new airfilter box (ala Trophy 160) + exhaust. The engine is also said to have new cam profiles - although the timing and lift properties of these remain unknown to me - anyone got the details of this cam?

If you are thinking of replicating this for your 1.8i, then the answer is pretty much yes, you can -

New air filter - best options are ITG Maxogen, PiperX Viper, K&N in a Rover 820 airbox
New throttle body (approx 100 quid from Mike Satur)
New exhaust - Mike Satur's systems are the ones we've tested as being the best available

That lot should be approx 8+5+5 bhp, although things are never quite that simple! :o(

If you want decent cams, might be best to chat to Piper for their fast road grind. You should get close to 140 bhp with this combination - to get more a new ECU becomes mandatory.

I've yet to try the FSE Fuel pressure regulator, so I've mentioned it in the above link, although it is something that can be considered as a way of circumventing the ECU's deficiencies in the fuel map with these kind of mods.
