I have been hearing Stroker and Blower a lot on this forum but I don't know what it means. Can someone please explain to a newb? Thanks.

a blower is an other term for Super Charger
Stroker means an engine with a longer than normal stroke

Rofl?


But really, A Stroked engine is just an engine where the pistons move further each time it turns. This gives the engine more displacement.

He was right so are you, you just elaborated more.

I realize he was right, but I just found it funny. Like looking up a word such as "Elaboration" and getting "The act of being more elaborate" XD

and stroking is done by at lest a different crank and connecting rods and probably pistons machining the block my be needed
and if you are going to stroke might as well bore at the same time
stroking increases the compression ratio most of the time but you can use diff heads and or pistons than some to achieve a more bootable engine

This is sounding more and more interesting with each post! Its just hard not to elongate the subject matter further! [&:]

and if you want install a blower its better to use a twin screw than a roots
a roots type just pumps air where as a screw type compresses the air
the roots type does cause a higher air pressure because it pumps air faster than the engine normally pulls it in creating a high pressure area in the manifold

where as a screw type compresses the air in the rotors and thus is more efficient

so you should stroke, bore, blow, and screw your engine to maximum performance

correct me if any of this is wrong

Well if youre going to bore and stroke you may as well port and polish [8D]

And yeah GG Ive looked stuff up before and the definition been like that.. I was like "well.. WTF DOES IT MEAN!?!?!" lol...

oh ya

the displacement of an engine is figured out by three things
1) the bore = diameter of a cylinder
2) the stroke = the up down distance the piston moves
3) the number of cylinders

if you take the bore represented by B the stroke represented by S and the number of cylinders represented by C then the equ goes like this
(B/2)*3.14=(cross section surface area)
((B/2)*3.14)*S=volume of one cylinder
(((B/2)*3.14)*S)*C= the displacement of the engine
