Re: air filters for my 147

the gsr kit is a complete intake system to the throttle body and as such provides genuine gains that an air filter kit alone cannot do.
gsr engineering.

Re: air filters for my 147

Peter is a great guy, but his kit is made to order, so your unlikely to get it tomorrow morning.

It is well worth the wait, having had one myself I can tell you that they do work.

Those who have had his kit and had it tested on a rolling road will tell you that there is a genuine power increase, which you are unlikely to get even half of with just a bolt on air filter.

Have a chat to him, he is on here as CPH.

Re: air filters for my 147

maybe - he has answered my calls at the airport before, then spoke for an hour!

Yes, I understand there has been problems, after all, he is a very small company, but of late he has taken on another guy and his act is much more together than the time of that post when he was struggling on his own, I think its unfair to judge his company when he was going through a difficult time, and...

...after all, no other kit touches his, so problems aside, it is worth it, just appreciate it is a small company.

That thread was only closed a few days ago and that was on the day that the whole thing was finally sorted out, but without the decency of an explanation (he must have known that 100s had viewed the thread). I tried to buy from GSR myself but most of my messages were not returned and the the kit was never sent as promised. I ve heard great things about the GSR stuff though, but based on my experience, the above thread and the extortionate price (250 odd quid for a filter and a bit of tube??!!)I m gonna go the DIY route.

I know what you mean but as a fluid engineer that's not strictly true Jasons, surely the idea is to get the air in quicker with less resistance?

A free flowing filter element alone will give a benefit, albeit so small it's hardly noticable. Presumably a GSR setup uses larger diameter pipes, straighter runs, bellmouth inlet, smoother transitions, less and smoother bends with smoother materials like silicone to achieve a noticable difference, coupled with a bigger filter area and free flowing filter element?

Suppose a new throttle body would set the average Joe back too much to widen that out and remove the bottleneck at the butterfly valve.

Re: air filters for my 147

As far as I m aware only turbo diesels and turbo petrols get meaningful gains from chipping (JTD goes from 150 to 190 brake). I think you d get about 5-10 brake more, maybe 10-15 if youve got an induction kit. Ring or email Red Dot or Angel tuning (loads of people recommend them on here) and ask, I might be wrong.
