Other cam? 2175cc

[Jesse/DVK]

How much benefit is there from using 1.5 rockers vs 1.4 rockers on the 86C cam? As i'm about to buy a set of Pauter rockers and they cost the same. Is it expected that the pistons need notching with .050 deckheight? And thinking of Bugpack 4046 or GB 273a springs.

Thanks!

Anyone? Would like to order asap

With either of those 2 springs you may encounter coil bind with a 1.5 Rocker, it all depends on how things work out, you have to trial assemble and measure/Check. Same with Notching, it depends on how much the head is flycut for compression.

But for a bolt together combo, an 86C with 1.4's and a non flycut head ie ( say a 55-60cc Chamber) you would be OK most likely.

Also, I doubt that you will be able to measure any difference in power when you are at 42 mm intake. They are on the upper side of effective with 1,4´s. - Going 44 mm valves they would make a difference if the port is good.

So 1.4 it will be

This is what i said , your springs and installed height will not handel the 1,5 rockers .

Another question, I now have a set of Pauter 1.4 rockers but which valve covers can I use with them? Do bolt on's work to with way the pauter rockers are bolted on the head?

Paulus has also those pauters, and he orderd the orange style CSP bolt on covers.
