Could also have the wheels machined to give a more S2 frinedly offset of ET30

For 450hp, definitely turbo ex cam, no 7A. Someone will buy the 7a for good money. Then reclock the turbo cams.

With turbo I of course mean 3b, aby, aan...

and why?? will work bad a car with 450hp and 7a exhaust cam??

my car works "perfectly" with a k26/27,Dhalback adjustable cam pulley, and 7A exhaust cam with 3B inlet cam of course.

i think that it is not necessary yes i know it,but if you have it ...why not??

2nd that my old coupe with 7a exhaust and 3b inlet usedc to go like the clappers

7a cams are good for one thing, regrinding

regrinding?? for what?? more agressive specs??

[GazzaG60]

i agree. dont see any performance gains with 7a. id change it back if i could be bothered.

[keithsw0]

im now confused

[Jamo]

In simple terms don't bother with the 7a cams

[GazzaG60]

just swapping the 7a did the following.

poorer everything till around 6500. then a little better.

still i belive there may be something in it with 2 timing pulleys and a lot of fiddling. like twin ex cam 16v. probly at say 600hp or so. repo would be able to cast some light here. cams are often a secret area though.

not worth it but once its in caw we be bothered to swap it back.

my car works well with both 3B cams and with 3B inlet + 7A exhaust...i´ve tested both styles and it seems that with 7A exhaust it is revving up faster
i have it intsalled ,because i´ve bought them in the past 2 years ago....and i had the chance for install it whem did the cam belts, other belts and Dhalback adjustable cam pulley

aniway i´ve changed the turbo since k24 7200 to k26/27 ... i am very happy with the hybrid how it runs and how my 7A ex cam rev faster

Repo has timed Terrybullwon and my cams in our cars and we both had 7A cams prior to his advice which were promptly sold..............

The 7A's can be timed ask Gazza says with custom cam wheels but getting that timing right, after watching Repo do mine I wouldn't like to try

Prosty and Audi_CQ have had the best results out the 7A. Audi CQ timing specs are posted on the forum, Prosty reground the cams to a secret spec and got 1000 rpm less leg

With the 7A exhaust only you lose torque low and mid and gain up high. With both 7A you get more lag but the car pulls harder on boost.

pays your money takes your choice

[GazzaG60]

if your happy with it then thats good.

id say the expectations were a lot higher than reality.
