Hi peeps
Just wondering if I bolt on a 70mm throttle body with the standard maf sensor and housing will there be any gain in power? Or do I meed the matching maf sensor also?
Cheers

What v8 are we talking about? I guess a early eb to el v8? If your looking at putting an AU throttle body on, without making other changes, it probably won't get you much if any gain. The standard HO manifold is rather small & restrictive, so is the factory EGR plate & the factory maf.

Does the engine have any other mods like extractors & exhaust or heads (ie gt40p's) ? If not, there won't be any noticeable gain from just changing the throttle body.

The car is a au2 xr8. It is only a 200kw so it didnt have a tickford throttle body but ive got one for it.
Im just not sure if the maf has to be changed to match it though?

No it doesn't, same MAF.

Without other mods and a ecu reprogram to suit a bigger TB, you probably won't gain much if anything at all.
