Supercharged 266/304 - Page 2

Urban Wheeler · 10-29-2009, 11:41 AM

IDK about boost numbers, but the crank and rods are pretty beefy, I bet with some good head gaskets one could run quite a bit of boost.

64dumptruck · 10-29-2009, 12:31 PM

Im going to port the heads out and install bbc springs and Murphy rocker arms i am currently looking into some custom push rods that are a little beefer. The engine work will not cost much since i can do it myself.

The eaton line of superchargers is a good idea, but i didnt have one at the time and i purchased the 8v92 for 50 bucks.

Does anybody have the center to center rod length for the 266/304 engines i need it to answer the question about boost pressures. Using the dynamic compression ratio caculator i could give a theoretical max boost, but whether or not the bottom end could take it is more of a practical issue.

If I remember it was pretty low, like 4-5 pounds.

Edit:
Found another thread where a dude talkes of running 7-10 psi through his 392.... Seach "scout boost"

I'm sure you are going to have to under-drive the hell out of it in order to keep the boost down. I am overdriven just a little with a KB 6-71 on a 490 Ci BBC. I hit about 10lbs at max rpms.

I was going to install an Eaton and a intercooler on the other SSII, but, I think I may take up desert style racing with it next year. So that is off the table.

64dumptruck · 10-29-2009, 02:48 PM

like i said its all pretty much speculation until you calculate the dynamic compression ratio, that would tell you how much boost you can go without spark knocking.

As for the drive ratio i am gunning for about 10% under driven.

shawdow man did you say you have a kenne bell, because you said it was a 671 and i thought all kb's were screw type not roots type, i would like to see a picture of the blower it sounds cool!

were also running a 6200lb pulling truck 557bbc, 1471 high helix, 50% overdriven, re striped it makes about 42lbs of boost.

Keith Black, teflon tipped rotors in the 6-71 that is on the BBC. I have a spare Weiand 6-71, a Eaton and a intercooler that I have sitting on the shelf.

Are you going to run an MSD BTM? Or some form of boost dependant timing?

After TBIing my 345 and turboing my 1.8l Honda I have often considered turbocharging an IH motor. I run 10psi on my 4cyl and make ~250whp... about a 100hp gain. Compared to the Honda motors the IH engines are straight beef. I would think they could handle 500hp easily... so long as you could pull timing / push fuel accurately enough to fight off detonation.

Can't wait to see this thing run, vids are required.

What's your point? He knows he can't run boost in that series, hence "off the table."

Exactly! That is why I don't compete in the Big Scout.

I would really like to see a supercharged IH motor on a dyno.

There is exceptions in some desert race organizations, but I believe it is for CARS that are factory turbo-ed.

budget76 · 10-30-2009, 01:46 PM

I know there's a vid floating around of a 345/92 with a blower on it on the dyno. The one that's in that mall crawler that gets posted every now and then.

I know when I was still on the BB every day there was a guy planning on turboing/twin turboing his SV. No idea if it ever got done though

Urban Wheeler · 10-30-2009, 03:03 PM

I posted that dyno video in another thread, I forget which one though.

The only other forced induction SV I know of is Chief's turbo motor.

Elvis38 · 10-30-2009, 05:15 PM

This one?

yota_lay · 10-30-2009, 05:21 PM

My point was he can run boost, it just has to be a diesel. Basically I was trying to convince shadow man He needs to build a diesel powerd desert scout.

Yota Lay off the post button before you F*ck up this fine thread.

JF · 10-30-2009, 11:23 PM

Is there any known record for most power from an IH mill?

probably need to be from an MV, or is there a BV?
saw my first 404 MV saturday, looked just like a 7.3idi

i run 8lbs in my 345 and its a sweet surge of power i have had it up to 15 lbs and it was more like and explosion of power but i think i was getting pre ingnition and im sure something would

wicked thred tho i look forward to seeing the end result and take some vids!!!

LOL, an MV really? 392's made more power then a 404 MV, and MV is still a small engine by international standards. MV's are CRAP, they run hot, but hot and eat exhaust manifolds like the are candy.

For an SV, I don't know if anyone would keep track. My guess would be Davesr's pulling 392.

So much ignorance in 2 little sentences

To the OP, it looks like a cool project

Binder · 10-31-2009, 12:28 PM

I'm sure you know boost will be limited by dynamic compression and fuel used......I didn't catch if you said what fuel you plan to use?

Project.

64dumptruck · 10-31-2009, 01:14 PM

since i am going to install a kegarator and a grill i was thinking propane, but i will probable go with multi port fuel injection, and 87 octane pump gas.

Might just add some methonol to the mix

Get on youtube and look for a video on a blown 345 IH. There was a feller with a built 392 who used to do truck pulls, that was a bad ass motor.

that 392 was Davesr that Diesel mentioned above. IIRC it was pushing 450+ horses, and the whole truck sold for <$5k

Thing was amazing, and if it hadn't gotten 1mpg I would have sold my scout and bought it. He had a hell of a time selling the thing I remember, because I dreamed every time there was a price drop

Urban Wheeler · 11-03-2009, 07:02 PM

Yeah, that one! I saw a video of it in action. He made a full pull and kept on going, the guy at the end with the flag had to run for his life!!
