Hi guys
Am in the process of hanging a couple of dellortos off the side of my A15 and was wandering if one manifold is better than another. And while we are mucking around on this side of the motor what extractors and mufflers would work the best.
We use the motor in motorkhanas ,sprint meetings and other basic club stuff.
Thanks
Bob

i think that most of the oval port manifolds are the same sort of thing. not much to be gained or lost in them.

extractors are the go (4into1) for off road stuff and im using hitech extractors with 2" out let pipe.

hey bob, twins are great but the down side is tunin the little suckers.My fiddling wiv these bits have forced me back to single carbs to stop so much valve bounce at high revs,ease of tuning and smoother rev range.Still twins offer far more grunt and low down tourque on 1200 to 1500 mills.Iv ran 1400 heads on 1200,s with twin SU,s and loved them but they tend to over rev em selfs to bits
