variety of rwd 4age headers

[70XIN]

there was a teeny bit of room on robo's motor. probably not much more than a cm though heh

XERO THEY ARE A VERY weird merge collector ,the 4 should all merge into 1 and have a cone or spear inside then taper then a taper cone back up to your disired dia

[lolwat]

yea but how much was that XD

[ke_70]

how does the slip joint work?

when it heats up does the inner pipe expand and then seal up?

offtopic. are you using a 20v sump cal? i thnk that gives abit more clearence+ other advantages. lazys got an adapter from tech arts?

[70XIN]

yeah exactly right, they usually leak a bit when cold but once warm are completely sealed up

[xero]

its a slip on collector with the insides tapering and spliced together. but i know what you talking about glen, my research has shown that with the collector being the desired diameter without the tapered peice makes no difference to power or flow.

so its fairly tight fit.

yes ke70 thats what ill be doing thats what you have to do to lower it..

how much power do you u would loose from factory headers to some like the one delzay has.

[ke_70]

depends highly on mods doesnt it? cams/intake/ect ect

you would probley want 421 also cal due to 7a lower revving? you probley know this i just wanna sound smart lol

[Delazy]

but to make the power he is claiming (160rwkw) from a 2L 7age he'll need massive cams, which will need massive revs also...

i ended up with 4-1 rather than the 4-2-1 that i ordered due to a mixup from the supplier...but im thinking that im glad i ended up with them...

[corknose]

no need for massive revs 8500 is plenty.

i think ill be going for 4-1. so i can get my power where i need it.
