supercharging an 8v gti

[danny_p]

don't spend money on headwork,   not worth it with boost  you'll just notice your boost pressure drop a bit  it's cheeper just to make the charger blow harder

Cheers danny! I'll talk to you in detail about it on msn at some pint in the evening sometime

[Khare]

oooo were about? Just passing through?

[axewielder]

whats better about the aba pistons? + cheers for starting an interesting thread khare really gets the imagination going

[Khare]

I think the ABA is the engine code for the mk4 2l 8v, correct me if I'm wrong.

[axewielder]

no its the US crossflow headed 2l 8v in mk3s just wondering why the pistons outta these are any better? but yeh its pretty similar to the mk4 one

[Khare]

Ahh right I see. I'll try and find them, but what are the advantages of them?

[axewielder]

yeh thats what im wondering, as far as i knew they are pretty much identical engines apart from the heads bein crossflow

[danny_p]

the ABA had lower compression in standard form as most engines for usa market do.

std ABA compression ratio 9:1 iirc ,  you get the cr as useing 2 headgaskets on a european engine but keep the quish zone roun the edge of the cylinder whitch is a feature
