[rs200]

HI
now i am in phase of getting parts for ma audi 200 20v.

the goal is 370-400 hp

is better to find a 7A or ADU cams??

thanks...

7A are easier to find. Both cams types will be able to give you the HP, but everything depends on the rest of your setup. Even 3B/AAN/ABY cams are fine. If you are after HP and don't care about spool-up time of the turbo take 7A.

you mean the ADU are better then 7A for a fester spool-up time?

[GazzaG60]

you will hit that target fine with standard aby cams. id leave the 7a's alone unless you have a turbo that like the top of the rpm scale.

[rs200]

aha now i understand.

the 7a cams are for high rpm?

you mean the ADU are better then 7A for a fester spool-up time?

Yes. Using both 7A cams gives you a delay of about 500-600 RPM, but give slightly higher HP top-end

what about using stock intake and 7A exhuast cam?

Gutless low down torque, ask 4wheeldrifter, Newsh

Good for larger turbo's and top end however.

To use 7A cams you need an adjustable cam pulley and adjustable sprocket to time them optimally to get low lag and good top end.

Thanks Mr Jamo, mine will be up for sale at soem point then

[rs200]

my plan is have full boost on 3000-6500 rpm.

so the point is use ADU cams.
