Looking on JHP site I came across these MAF pipes which claim to give a power increase of up to 5kw. Question is would you need a tune to get that extra power out or is this a cheap and easy way of gaining a couple of extra horses for anyone that can work a screwdriver?

It is hard to tell which one pipe that is. The genuine article you want is the HSV VTII/VX /VY GTS pipe. I will find the part number in due course. This one can be made to fit with and without a MAF. I have one on my older car with a MAF. However when tune time comes and it goes MAFless, I can jsut substitute the rubber joiner where the MAF is.
The other pipe is the VYII HSV pipe that uses the MAF. This pipe looks similar however it tapers down near the MAF to a smaller diameter.
The do work ok, but a tune optimises them! I am sure one of the sponsors would have them in stock too!

Just put the JHP one on the other night. Can't remember the part number or exact description, but it said something about 300kW.

I already had a tune in the car, and it's hard to judge any noticeable performance increase from just the MAF pipe. The heart says "yes I can really feel it", the head says "you're just imagining it".

If it's gonna make you happy, just do it!

Forgot to add: Yes it's a screwdriver job. And the VAT levied by Customs came to £17 and something.

Several members, including myself, have the CS Performance Carbon Fibre MAF/MAFless pipe available from:

www.andy-saunders.co.uk/csperformance/

IIRC WRC used to stock them although I bought mine directly from Andy. All pipes are hand made.

It makes life easier if you also order the "Pipe Fix Kit". It consists of two large jubilee clips and a short section of high quality hose to connect the pipe to the throttle body & MAF to allow flex.

I am currently running MAFless with pretty damn good results. Wiill know in teh next couple of weeks if this is goin gto stay this way if so I have MAF pipe and 85mm MAF that well be up for grabs. If you have this you will need tuning but resulst are very good over standard especially if you do exhaust and headers.

On that front may have a set of Pacemakers 4 into 1's for sale very soon if anyone is interested. Will make a huge difference to sound and peformance over standard...

All items above supplied through Wortec and fitted by one or more of their apporved dealers.

Ah, Sean, Mafless, nice.
Im running an OTRCAI, which replaces the pipework alltogether. Are you running something similar these days?
What size primaries and collector are on your "spare" headers? What did you replace them with?

Hi Rich

yep running an OTRCAI as well damn good IMHO.

Header have not come off yet. Thinking about one of the new Wortec systems with interchangeable boxes etc. I will get the sizes for as I do not know.

hmm that carbon fibre job looks the dog's danglies. Oh what to do, what to do - buy one of those, wait and see if Sean sells his 85mm maf and pipe or go for the hsv one. Guess whichever I go for its gotta be better than the standard pipe.

I must confess that Paul from Wortec said it might detune the car a little but I went ahead and bought it anyway because it looks so darned scrummy.

I can't say I actually notice any performance degradation at all although those with more finesse & skill than me might be able to.

Anything that potentially changes volumetric efficiency may cause the tune to go off to some extent. But only when cold and at WOT. Part throttle the O2 sensors handle things. More major stuff like full exhaust, otrcai, mafless etc, you will definately want to adjust.

From my other home!
06M3990701 VX GTS Pipe - Air flow meter to throttle body
06M3990702 VX GTS Rubber joiner - (Deletes Air flow meter)

I am not sure they fit the LS2 6.0 litre cars but they definately fit everything else.
