haha - can't believe I let that slide

Very nice OHV engine, btw. I'm excited for V10s somewhere down the line to make engines like that, DI OHV.

Re: V8 Engine Build [Challenge]

This has proven to be a very interesting exercise for me, as I normally spring for high-revving engines with top end power. Also, I shall join in saying damn that pushrod engine is nicely balanced. I've used it as a performance benchmark to make something a bit cheaper, a bit more powerful, and a bit more efficient, but less reliable and with more emissions (though still quite low!)

It does spool a bit later than the most recent post, that >1000ft-lbs at 1900rpm makes me giggle.

EDIT: Also lolololol my 2000th post!? I didn't even notice it creeping up on me.

Re: V8 Engine Build [Challenge]

Very good Strop, but your emissions are higher then the max allowed of 40!

Re: V8 Engine Build [Challenge]

lolololol whoops I can't read. Thanks for the heads up.

All that said, I decided hang it, let's see what we can do maxing out the limits and going for 300PU, and bumping on the edge of the other limits too:

I did play around with the OHV too, and boy does it make a number of things easier. The maximum torque is a little less but it's cheaper, more reliable and extremely capable in this application.

Re: V8 Engine Build [Challenge]

Will you guys accept my Tri-SO Vry-Hrd 3 Valve SOHC? (Rules state 2 or 4 valve, but what about 3 which is between the two?)

This one I went for the full 300 production units with.

Now convert it to a DA-OHC head and see what you can come up with..

Re: V8 Engine Build [Challenge]

Here's what I put together. I went for low production costs as well as low man hours while still making over 1000 HP and ft-lbs of torque.

Re: V8 Engine Build [Challenge]

So I went back to the drawing board and decided to max out my Production Units since I left over 100 of them on the table with my last attempt. I came out with max performance and max economy variants. Here's my most economic motor for this challenge:

I managed to get a higher economy by using a race intake (Around 33.43% IIRC), but I would have had a reliability rating of 71, so I gave up a fraction of a percent of economy for this practically bulletproof monstrosity of a motor.

My most powerful:
