Ok A New Subject Maybe U Engine Guroos Can Educate Me On

[just a nuder 6]

I AM FROM THE NATURALY ASPIRATED WORLD WHERE YOU RUN FLAT TOP PISTONS AND A TIGHT QUENCH TO SUPRESS DETONATION
I KNOW THAT TURBO CARS ARE A WHOLE DIFFERENT ANIMAL
FUN AS I AM FINDING OUT BUT DIFFERENT.

MY QUESTION IS WHAT OTHER THINGS DO YOU DO IN THESE SENSITIVE TURBO MOTORS BESIDES THROWING ALOT OF ALCOHOL AT IT TO KEEP IT FROM DETONTATING

WHAT PISTON QUECHES ARE NORMALY RUN?
WHAT CC HEADS?
DO MANY FOLKS RUN CERAMIC AND THEMAL BARIER COATINGS?
ARE THE WATER PUMPS REVERSE FLOW WEAR THE COLLANT GOES THRU THE HEAD BEFORE THE BLOCK OR ARE THEY CONVENTIONAL VICE VERSA?
ROD LENGTHS CRANK LENTHS?
ETC. ETC,

SHOW OFF!!! TELL ME WHAT YOU KNOW BABY!!!!

Advanced engine fuel and timing managment. 8.5:1 compression, and intercooling. thats it!

This is highly sensitive information you're asking. We can't just willy-nilly, let this information out into the NA world.

o you misunderstand

i own a gn now
not in na world anymore looking at a rebuild in the near future and was looking for the best way to get the most p o w e r

 

[Quick6'n'-K.C.]

if it aint broke dont take it apart-
lots of stock motors that have been into the 11s never have had the valve covers off-

lots of boost, lots of timing, lots of alky make P O W E R !!!

That would actually mean staying with the oem ecm.
The aftermarkets compromise complexity for making them *easier* to work with...


On an engine like the SBC, reverse cooling is a good idea, but the V6 Buicks are done ALOT better then the Chevs. The flow pattern, areas, etc, are alot more like a Ford, and neither really benefit from reverse cooling.


Alky, and thermal coatings are both good things, IMO.

ok sweet but..

does anybody mess around with tighter piston quenches and thermal barrier and anti-friction coatings

another theory flotin around is the short rod theory

ther idea is that a shorter rod and a longer stroker crank reduces the chance for detonation because the piston dwells at TDC for a shorter period of time due to the short rod ratio

can these blocks accept a long stroke crank?

just somethin to think about.

First the blocks must be originally designed for reverse cooling(like the LT1). Second tighter quench means an increased static comp. ratio. At the extreme most I'd recommend no higher than 9 to 1 on a turbo motor. You're better at making more power with an engine that has an 8.5 to 1 ratio and dialing in boost and timing and an intercooler. I personally don't like shorter connecting rods, it creates more side load stress on the piston and cylinder wall which can throw a rod.
