when i picked my engine up last year i got a later escos plenum and spacer at the same time
im going to fit the plenum but is there any advantage to me fitting the spacer
running a 34 with greys

...not really as you are gonna max out at 400bhp anyway...and even the 2wd plenum will see 420 ish bhp before any restriction.

now thats what i call a sales man-
sell me a part then tell's me i dont need it

tracktoy

although the 2wd plenum will 'max out' at 420, would there be any advantage to having more capacity?

same as with injectors running at 100% not being as good as a bigger injector running at 75%?

Forgot i sold you that

...yes it will give an extra 45bhp

im sure jay cos had to trim more fuel into his fuel map when he fitted his

I have one but to date have not seen any EVIDENCE that they do anything, and was having this very discussion about my one with someone very knowledgeable, who said it was his opinion it was another gimmick, and would do nothing to very little, or a turbo car such as cossie.
I ammin two minds wether to us it or not.
Would be interesting to hear and see any before + after printouts though.

my afr was set to 11.8 from 18 psi to 32 psi without the spacer . with spacer it was 12.6 afr so i dialed more fuel in so there was a difference to airflow through the manifold

so in theory more air more power but unfortunatly wasnt tested before and after on the roller's

tabetha

Thanks that is very interesting as it obviously allowed more air flow, did you notice any other difference ie lower down the revs more torque ?

yes it did pull better to a tad more lively lower down but that is just the arse dyno should have really done it properly before and after on the rollers

tracktoy

so if i do fit it then - its gonna need a remap ?

Jay,
