Flowing a G60 throttle body

[Rustynuts 0]

Well now i got two throttle bodies to fix my broken one, is it worth getting the spare one flowed. Does the expenditure result in a good gain in power or torque?

 

 

What else makes it worth doing?

 

Should i get the inlet manifold flowed to match?

I'd start spending money flowing the exhaust manifold or fitting a 4-1 first, cylinder head next & work forward from there.

What benefits can be had from doing the manifold, again some kind of figures would be good.

Doing the Exhaust manifold doesn't increase the bhp, however it will increase the torque of the engine!

Rustynuts, Doing the exhaust manifold alone will yeild very little in the way of BHP. It will, however, enable the engine to breathe more easily & you'll get much more benefit from any further mods that you do.

What's the best method of flowing the exhaust manifold?

If youve got to fix your throttlebody you might aswell flow it at same time.I did mine with a dremmel,took about a day to get the desired finish i wanted.I wouldnt worry about bhp figures,as long as you feel an improvement,then its worth doin! i thinned the spindle out on the small butterfly and countersunk the screws and the car picks up alot better now.

shouldnt cost you anymore than £20 including buying a dremmel!!!!!

Well i could do with some more torque thats for sure. Will have a look into getting the spare one flowed.

 

Talking about flowing, i may just use the knackered throttle body to practise a bit of flowing.

 

Have you got before and after pics for your flusted?

get header, take throttle body, flow it and get a chopped intake manifold then see what your car does. EIPtuning.com
