and to put this 8v/16v thing to bed. my mk2. i had a 2.0 8v. big valve head. newman 268'. ported inlet and exhaust manifolds. it made 138hp and 145lbft. and it cost a fortune to build.
i then put in a 16v abf running digi 3.2. 149.5hp 139lbft. same jetex exhaust as the 8v. also the same lightened fly and aug 020 box.
the only difference i can tell is the 16v has a little less grunt at the lower end. not worrying. but i can still potter around at 30 in 5th everywhere.
yet, where the 8v, even with its oversized valves and longer duration, higher lift cam, used to run out of puff at 6k, the 16v pulls to 7k and gets there a hell of alot quicker.
my favorite piece of private track, a long'ish straight, the car is a good 20mph quicker. thats off the clock blasting through 3-5 between 5-6.5k in all gears.
with a ported head and matched inlet track/ex. custom fueling map, this car will be a daily animal
