EF XR6 from then till now

[Duffman]

Bought this in average condition about 6months ago. stock apart from a dodgey 2.5in system.
chucked a redback catback and some pacies on it, a crow 549 cam and j3 in it and ran this

[Duffman]

next was headwork

then custom 3in system and bored out tb

[Duffman]

this wasnt enough so next came the custom grind from surecam and new springs. just ran this today


there are a lot of other little details bits and pieces, feel free to ask if anyones curious

[Duffman]

3rd gear is a typo it was 4th clearly at 190kmh+

[Jayedxr6]

Awsome power man. Any video's?

[Duffman]

cheers mate. no sorry

[Duffman]

need to come up with a better air intake for this, any ideas ppl? anyone fitted a BA airbox to a EF?

[Jayedxr6]

Why a box? Try a pod in the guard with a 3 inch intake? People have used ba boxes though

When mine was NA I cut a big hole in the bottom of the airbox and fed ducting up to it from the front bumper. Worked good enough for me to run a 14.1 quarter mile

[Jayedxr6]

Yer I actually removed a headlight (ed xr6)and fed 90mm pvc straight into the box wich had a pod

Or an EL GT snorkel if you can find one.

Early Ba xr8/gt stock air boxes are cheap
has a 3.5" pod almost mounts in the factory spot with the Ba bracket.

[Duffman]

i have a pod in the box with 3in piping and twin snorkles, its still pulling vac past 6000 revs so its restricting. pods arent the way to go in my experience. pod in the guard is a terrible idea as it is a low pressure area at high speed. work fine on the dyno but shit on the track

[Duffman]

new intake system

[Jayedxr6]

Looks good. Whats next?

[Duffman]

plug leads, play with the cam timing, fit the new injectors and dyno again

[Duffman]

not a huge gain but il take it. better AFRs and a bit fatter curve
