Inside the ILMOR V-10!!

[ILMORdude]

For your viewing pleasure!! I give you a pictoral build of the ILMOR V-10 725.
:driving: Enjoy..........

[ILMORdude]

And a few more..............

[Sea-Dated]

Cool. Wanna donate a pair of those to test their longevity in a Cafe' Racer? :cheers2:

[C_Spray]

Well, THAT ought to put to rest any questions about whether or not these engines have custom crankshafts...

Cool how the put the crankshaft position wheel in the middle of the crank, where it's quietest.

[ILMORdude]

More to follow!!! Stay tuned........

[Buoy]

Very cool!!

Or how about just one to see what a 24 Pantera will do with one.:sifone:

[fantastixvoyage]

Lookin' good as usual.

Curious, with the mention of the crankshafts who does the crankshafts and what material?

Do all the engines get torn down like this or are only the 650s built on the line at Conner?

[imco offshore]

ok i have got to ask HOW MUCH IS A 650

650's @ Conner. Forged Steel from SMI.

Shhhhhhhhhhhh!!! :driving:

[ILMORdude]

Line 'em up.......

[C_Spray]

Line 'em up.......Hmmm....

So maybe the connecting rods are custom as well? :rolleyes:

[Uncle Dave]

The quality of these parts is fantastic.

I havent seen the old block to compare, but the new piece is a work of art.

[MacGyver]

Great shots! Keep 'em coming!

[MacGyver]

So the main bearing caps are 4 bolt, 2 inside and 2 exterior? Never seen that before. Cool stuff.

[Uncle Dave]

Not sure, but I think externally side bolted mains is an expansion control technique as much as a strength thing.

I would guess the caps are ductile iron.
Expansion with alum caps in an aluminum (alloy) block would be too much and the engine would lose oil pressure when hot- iron main caps helps maintain oil pressure.

I wonder how big you can bore it?

Also note - the lifter galleries are closed.

Wow! That motor is very impressive! How about the pistons? Are they JE

[C_Spray]

Wow! That motor is very impressive! How about the pistons? Are they JEIlmor makes their own pistons for the Honda Indy Racing League engines (from solid bar stock!!), but I would guess that these are Mahle forged units...

[ILMORdude]

Few more.........

[ILMORdude]

Few more............:driving:

[C_Spray]

In that first picture, it looks like the steel strip alongside the crank is a oil scraper? I see that it's notched just enough to clear the rods...

So - Are the pistons Mahle? Or are they "other"?.....

Correct on the scraper, and "undisclosed" is the word..............

[NASCAT]

My guess is several parts made across the pond out of unobtanium!

Slowley......we will get you to come to the "I" side.....:driving:
