Hi ive got a blobeye running a alcatek ecu with anti lag and and just wanted to know if anyone else had the same thing happen to them. When i had my std headers on there the anti lag worked awesome but now i have changed over to rcm headers its crap hardly any bangs at all. Incase anyone ask's it has been remapped with the new headers cheers

 

Not wise running AL through them, they will be cracked in no time, is this a road car?

 

out of interest do you need to remap if you change the headers?

 

I Hardly do it to be honest bud, i just wanted to know why its made such a difference

 

Have a look at the WMS headers (Williams Motorsport), at £250 delivered theyre half the price of RCM and I know of several rally cars running antilag on them without issue. Thats proper antilag mind you, not just a poppy farty noise.

 

Poor quality in comparison to the GT Spec ones, that is what we found on the set a friend purchased directly from WMS (design may have changed since as it was about 18 months ago). In regards to sound changing mostly due to going from a cast manifold to a stainless steel one

 

Ok that makes sense so any after market headers will be the same. Out of interest what sort of power are std ported headers good for. Thanks

 

I run 418bhp on a standard ported set but its at this point theyre starting to hold me back so will be changing soon

 

They will be no good for me then as im going 2.1 stroker
