cleaning ANYthing on an engine, a quick spritz or easy off oven cleaner. it'll flow your F'ing mind. spray on.. 20-40 seconds.. wipe clean... pistons and all come out looking like you just pulled them from a shelf. an i DO loves me some soda blasting.. phenomenal what baking soda and a eastwood spe...

ya you'll want it practically on there. i have done some high-end M3 stuff ( mostly E36 as well) and any time we built a rarecar that was the ticket.. make it touch. just barely. as far as a scraper on dry-sump.. it IS effective to a degree. you figure you're stripping off a parasitic loss.. there ...

it would be interesting to note the primary voltage to the plug coil(s)at he beginning and end of the run to chart voltage drop.. you figure theres a massive ratio there where 1 volt lost could equal thousands of secondary volts gone as well.. depending on the transformer ratio.. if h ad to guess.....

one of the biggest advances so far with streetbikes that we've seen from trickle-down moto-GP stuff IS yamaha's R1 wit the crossplane crank firing 1-2-3-4. the sole purpose of that was traction and linearity of throttle response and power build. loved the article on the autograss big bang stuff. in...

i'm still kinda in shock over knurled pistons!!!

that is pretty damn slick, honestly.. i can imagine tho theres a possiblity that was a "homemade" tool with a almost gear puller-esque looking contraption with the arms expandable via a driven bolt and wedge, on the end of the arms, knurling wheels intended for use with a lathe. IF.. i ha...

i appreciate the input guys!. i was told ( by quite a few people, actually, some who are engine builders, some, mechanical engineers who know a good bit about motors..) that there IS a laminar flow along the port walls.. setting up a sort of mini boundary layer of air between the intake charge and ...

how relevant is laminar flow in relation to this? as with a previous thread, we all agreed that exhaust tuning goes out the window on boost for the most part. now, i would have to "assume" that laminar flow will be pretty much null and void on boost? so, whether my intake runners reflect ...
