This does seem to come in at a very reasonable weight. Looks like no
flywheel in the pictures and their is no weight posted for it or clutch, unless it was included in the transmission weight.

Duratec 2.0 info from Mark Conley:


http://autos.groups.yahoo.com/group/Locost_North_America/message/41865

Mark Conley:
I pulled most things off and weighed them separately:

engine 192lbs
exhaust (and cat) 20lbs
belt tensioner 26oz
injector rail and injectors 27 oz
power steering pump 120oz
egr valve 13oz
alternator 12lbs
intake (no throttle body and partly broken) 101oz
engine harness (cut at firewall) 45oz
coolant hoses (that I have) 45oz


Some dimensions:

Length from flywheel to front pulley (no flywheel, to end of crank) 19.5"
Width at widest part of block (Where Tranny mounts) 14.5"
Width at widest part of head (At front) 11" (general width) 8.5"
Width including stock manifolds (exhaust not usable) +8" for stock intake.
Height from cam cover to bottom of block (tall side)19" (short side)
18.25"
Note: height of coil on plugs in pictures from above link.
Height overall (from bottom of sump to cam cover) 24"

Length of gearbox from bellhousing to tailshaft 32"
Width of bellhousing 14.5"
Length of bellhousing (at top) 6.5"
Note: see pictures, bell housing tapers to different lengths on sides.
Height of bellhousing 14.25"
Taper of bellhousing Not sure how to get, look at pictues.
Width of gearbox case 8"
Length of gearbox case 10.5"
Height of gearbox case 10.5"
Length of tailshaft 12" (includes 5/6 gear casing)
Weight of gearbox (dry) 101 lbs
Weight of bellhousing (if removable) N/A

Two more data points.

From KB58:

Quote:
My brother just weighed his L67 supercharged V6 - 430lbs minus the alternator, so figure 445-450 for the complete engine.

The transmission weighs 100lbs even, including the clutch and pressure plate.


From William's Racing:
Cosworth BDA complete with carbs, flywheel, clutch is a hair over 200 lbs., 200+ HP.

The BDA is built on an xflow bottom end and the xflows now have aluminum heads so they should also come in at a similar weight.

Hmmm...

Honda B18C (VTEC)

Block ... 67 lbs
Head ... 38 lbs (loaded: valves, springs, cams, etc.)
Rods ..... 5 lbs
Pistons... 2 lbs
Crank .. 33 lbs

Total ... 145 lbs for "longblock"

Observation: The factory "externals" (flywheel, manifolds, cam cover, oil pan, water pump, etc.) must weigh ~160-170 lbs ... that's more than the longblock!


Ford 302 V8 (i.e. 5.0)

Block ... 83 lbs (ALUMINUM)
Heads .. 46 lbs (Aluminum... pair, loaded: valves, springs, etc.)
Cam .... 11 lbs (incl. lifters, pushrods)
Rods .... 11 lbs
Pistons... 8 lbs .. (corrected)
Crank .. 48 lbs

Total ... 207 lbs for "longblock"

Observation: Too bad Ford never made the aluminum block for the low-deck SBF... Dart aluminum block costs $4,900. Careful selection of externals (fabbed sheet manifold and oil pan, aluminum flywheel, etc.) could yield that mythical "under 300 lbs V8"... with 43% more displacement and much better heads than the Buick/Olds/Rover 3500. Certainly would be a Seven Supercar. 8)

Honda H22:

Shortblock ... 123 lbs. (shown on scale)
Head ............. 48 lbs. ("10 lbs heavier than B16")

Total ........... 171 lbs. "longblock"


H transaxle ... 96 lbs.
B transaxle ... 90 lbs.

Observation: Again, the factory externals weigh as much or more than the longblock (based on Kurt's 475 lbs total).

(B16 shortblock on scale 104 lbs... D16 Shortblock (+oil pan) on scale 100 lbs)

SportsCarDesigner - Clearly you forgot the wrist pins!

Geez, for a day I thought we made some progress. Those numbers are so light - I'm just confused again.

I went downstairs and grabbed a connecting rod/piston from my old FF engine. It weighs 2.75 lbs on my kitchen scale, probably pretty accurate ( actualy 2 lbs, 11 and 3/4 ounces )

This is for a 1600 cc motor, so the rods for that Ford 302 sound very light. I think the rods in the xflow motor are well regarded...

Sigh... I'm afraid the brain hurting stage of this Locost build is going to take a lot longer then I thought.

Yup (if the scale is right). And you can get a chain driven LSD for 12 lbs!
