turbo maps, and related turbo info

then get steel head gaskets, ARP head studs, main studs, rods bolts, hone the cylinders, gap the rings, and boost it. if it breaks, use a poncho motor. but enjoy the shit man... i wish i had big power at my fingertips like that. im stuck with lowly inline 6 untill something really big comes along. been getting my ass kicked for 200 dollar jobs lately.

Tired of crap sidejobs too Phil.
Has to be better.


Go Drag Racing Yourself & ME 2.

Clicked on the link Grumpy.
Real nice workmanship.
Has to expensive.
 
yeah! its a damn shame yet, quality always seems to cost far more than we would like it too!

you can already see that the newer LS engines and adding an inter-cooled turbo are going to be a fairly common way to get massive power in the future

Normally Aspirated and Big Block Cubes.
Nitrous shot just in case.
I can afford that in 2015.

theres a grudge racer down here in south florida named big low, g boy big block back half car, fiberglass front end. anyway big lows big block is over 700 cubes and put down four digits to the tire on the muscle... but just to be sure hes out front he also has 1000hp shot of nitrous on tap. thats not a typo... one thousand horsepowers worth of nitrous... it used to be multi staged but i think its progresive now. anyway the car boogies... here it is a few years ago and several hundred horsepower ago...

Pretty Kool Phil.

Its not so easy allways putting down 2000 HP on the street though.
STREET RACING .

yea the car doesnt work as well on the street as it does on a track, obviously, but they have the car pretty good n figured out... theyve been playing with it for years.

MAP-02.jpg

This is a compressor map of a Garrett GTX 4594R turbocharger that we are using in the body of the story for examples. The large red X marks a spot on the map where the turbo is moving over 80 lbs/min. of air – roughly equivalent to 800 hp worth of air. This is also within the 74 percent adiabatic efficiency curve, which means this turbo is doing an excellent job.
A compressor map is a sophisticated graph that tells you just how efficient a supercharger or turbocharger is at creating pressure. The whole reason for these devices is to move extra air into the engine than it would normally consume by employing atmospheric pressure. It’s this simple – pushing more air into the engine will make more power. While most maps refer to turbochargers, similar maps are available for centrifugal blowers, positive displacement superchargers like the venerable 6-71 GMC blowers, as well as the latest generation Eaton and Lysholm screw superchargers.

Increased air density is what we are seeking. You can think of air density in terms of weight since air has mass. Think of this as a column of air extending from sea level all the way to the edge of space. This column has enough mass to create pressure – 14.7 psi at the bottom of the column at sea level. Normally aspirated engines use this atmospheric pressure to push air into the cylinders. In order to make more power, we need a way to move more air than what the engine can take in without help.

The key to a good turbo or blower is not just how much air it moves, but how efficiently it compresses the air. We measure this efficiency in terms of adding the least amount of heat. We already know that as a pump creates pressure, the compressed gas (air in this case) will naturally increase in temperature. Just touch the housing of a shop air compressor to understand this concept.
 
Just want to let you guys know with 76 mm Turbo kits & Bigger do not use any smaller than -10 AN Turbo Charger Oil return line size back to the oil pan.
Use 10 -12 AN only.
Oil gets backed up otherwise.
Returned by gravity.

The Callaway Twin Turbo Corvettes had a special scavenge crankshaft pump just for this purpose to return oil drain back turbos for this reason.
 
The hardware with most Turbo kits is a joke.
Need to Fab near all.
Worth it in the end when done.
