Plenum spacers

[Marky67]

Hi people, no mods at all carried out on my z, totally stock 05. Are there any gains to be had by fitting a plenum spacer to the 05? And if you do does it get in the way over the strut?

 

cheers

Depends what size you fit.  I think the half inch one is fine. As to the gains, it's better when you combine with an uprev map.

Yes there are gains to be had though you’d need an up-rev  afterwards to see any really. as for the strut brace that will have to be spaced up  aswell though usually comes as a whole spacer kit.

What’s involved with the uprev lads. Enquirer recently with a mapping garage in the north east and was told they can only get tiny gains on the 05 z

[Jay84]

 Horsham, Abbey or TDI north are your best bets,  it's around 400-500 quid. I've not had it done though so I'm not your best answer.

I wouldn’t get a remap after just fitting a plenum spacer because it would not be money well spent. Do all your performance mods and then remap ie intakes,exhaust,plenum spacer and then do it. You won’t see any noticeable gains with just a plenum spacer alone.

I'm fitting a Motordyne 5/16" spacer tonight, I'll let you know the reults if your interested  .

Avoid aluminium intake pipes unless properly coated 

 

At abbey last week I saw intake temps almost triple with the bonnet down

 

Bonnet up 277 at the wheel 

Bonnet down 269 at the wheel 

 

Heat soak is horrific on these cars with non coated shiney aluminium intake pipes

I managed to find time to fit mine Sunday. It took a little longer to fit than expected but I gave myself the chance to familiarise myself with the engine  .

First impressions, It feels more responsive, pulls harder and has a noticeable deeper note to the exhaust. Another piece of the puzzle found ready for a remap.
