MG MGF Technical - 52mm TB

Hi,

Is it worth putting a 52mm TB onto a plastic inlet some say its not worth it? is that true?

Andy.

Andy, I assume that by "plastic inlet" you mean the standard 1.8mpi inlet manifold.

Most of the people I know have this setup and only heard good comments. Never seen a dyno though. But throttle response is IMO better.

cheers,

Yes its the std 1.8 inlet manifold (plastic) so it is worth it then?
Andy

For me it was.

payed 30 EUR for GM TB from breakers. And yes, it was worth it, including huge DIY fun.

DVA's K05 kit - well done Vic!

You might want to chat to Kingsley - he's the only other F owner I know with this kit.

Are you fitting it yourself?

Andy - I've done exactly as you have: fitted a 52mm TB onto a standard MPi plenum - and have RR the result! Conclusion? Gained 1 bhp. Perhaps 2-3 lb.ft else where in the rev range. Nothing to get excited about. But the throttle response is much better (especially from small throttle openings - thank the larger choke/ butterfly valve size for this: any movement is going to result in a larger opening compared to a 48mm TB) - and probably worth it for that 'feature' alone :o)

Must get round to posting that RR curve onto the website sometime...!
