 LS2 500CID
Leidsin ühe huvitava jutuotsa. 
quote:
Here is some info and pictures of our 500 cubic inch ls2 project we have been currently working on here at the school.
Some information about the motor:
Bore - 4.2025" Outfitted with Custom Wiseco 26cc Dish Pistons
Stroke - 4.500" = 500 Cubic Inches
Connecting Rods - 6.800" Carrillo Billet A-Beam
Cam - Custom ground Comp Cams Hydraulic Roller
Heads - LS7 heads that have been cleaned up
Intake - Factory LS7 Intake
This is hosting ERL's Deck Plate and Sleeving they are offering to help allow us to reach the 500 cubic inch limit.
We are right at a 10.9:1 compression ratio and we are looking to make around 650 to 700 horsepower Naturally Aspirated on Pump Gas.

Paar sõna veel juurde.

ERL Performance 500-cid LS2
Short-Block

If you thought the new 427-cube LS7 was the big dog on the block, think again. ERL Performance now offers 500 cubic-inch short blocks in crate form or as kits. ERL starts with an LS2 block and fits it with "Superdeck" deck plates to arrive at a 10.2-inch deck height. The Superdeck system employs integrated bore sleeves for long rods and plenty of stroke--up to 4.5 inches. These short-blocks are built to order, so a multitude of combos are possible; rod size (Carillo) ranges from 6.600- to 6.800-inch, bore (Wiseco pistons) ranges from 4.155- to 4.205-inch, and stroke (a Lunati forging) starts at 4.250 inches. ERL even developed it's own big-bore MLS gaskets with Cometic, a leader in the field. Add ERL's intake port spacers to your heads and over 1,000 hp is possible. One of these will set you back about $10K.

Üks võrdlemisi tõsiseltvõetav tänavamootor, kui jõuülekanne ja muu vajalik viia selle võimsusega vastavusse, saab toreda sportliku cruiseri.

Üks viide ka umbkaudsele võimsusreitingule vabalthingavalt:

building one of the world’s first 500ci Gen III small-blocks. Thanks to a set of ported LS7 heads, projected output is in the 650-700 hp range on pump gas with a very conservative cam.

4.5" väntvõll on juba üsna tavaline. Saadaval juba mõnda aega näiteks WARHAWK 481 kombinatsioonis.
Puhtteoreetiliselt annaks 4.250 bore ja 4.600 stroke kokku ~522 CID ( umbes 8,55L) kombinatsiooni. Praktikas tundub olema 4.250 bore siiski vähepopulaarne, töökindlus väheneb oluliselt. |
