What would you build if limited to 372ci - with boost as an option

[cojohnso]

It wouldn't be cheating, just moves you to AA engine class. Then record is 246 for unblown or 255 for blown

That's fast. That's nearly 100 MPH faster than I have driven. I would be fearful of flight.

If God meant man to fly? He wouldn't have invented the "wing."

Hence my want to get below 372ci. My personal goal has always been 200, so 224 seems reachable. Kinda. Maybe. On paper

 

[71GSSDemon]

Only nine mph for a blower? Wow!

Just because you have more power, doesn't mean you can get traction out there. And, it just means someone hasn't built that and made it work.

Some Aussie friends went 250mph at Bonneville World Finals today in A/CBFALT. 1972 Charger Valiant. 496ci dual plug hemi, crank driven procharger, methanol, liberty 5spd and quickchange. Hope they back that up tomorrow for the record.

The salt is a whole different animal,,,,,tires spin very easily.

Very true. George Eystons seven ton, eight tire lsr holding car was spinning tires at 300 plus mph at full throttle application, on the salt. In 1938!

Speed Demon is said to have traction control a move at 400+. Record of 493IIRC and never fully used all the power

My friend Sid will hopefully be the first piston driven car to breach 500mph next summer.

 

[MOPARMAGA]

Definitely cant use the Hellcat blower. Can't run EFI.

Tunnel ram though with 2 1150s will work

That’s terrifying

His was the streamliner that blew up at Speed Week this year. Flaw in pre-made fuel line. Blew panels off, lit car and driver on fire. Car will be fixed and back for all 3 events next summer. He has been on some great streamliner crews over the years!

 

[71GSSDemon]

AA blown gas (or alcohol, fuel) is only 255mph? Seems like that could be a record worth chasing.

I thought we were friends, you're killing me

We are. I promise I’ll bring out the best in you.

I remember you telling me about that. It’s a good reminder of how important the safety equipment is on any race vehicle. So lucky no one was seriously hurt in that deal.

In talking with him, he moved here from New Zealand to work on Gale Banks' streamliner, was an engine guy for Al Tiege, rebuilt the Chet Herbert 4 engine liner, etc. Very smart guy. He bore scoped the fuel line and found the weak spot.

Good. And Hmmmmm

 

[71GSSDemon]

So, do I remember correctly that Max Wedge sized heads don't work well with the smaller bore of a 383?

Please expand on this. Have you personally destroyed an engine at 751hp due to a block failure?

Yes, exactly at 750.1.

 

[TT5.9mag]

Yes, exactly at 750.1.

I love that reply. Thank you. I was just looking for some kind of direct experience because I personally have seen much more hp made successfully (about 1200) and I am planning on making quite a bit more than 750.1, eventually around double.

That's the engine I get to borrow, right? I mean, its just for about a week....

With what? Big block or small block? Mopar? Stock block or MP block. Hemi gen 2 or a gen 3 Hemi perhaps? Somehow I thought were were talking about stock 340's, 360's or 383's?

 

[71GSSDemon]

With boost and a late firing event, combustion pushing merely straight down, I would bet these engines would handle way more than most think. High combustion/compression pressures take heavy tolls.

Small block magnum. Twin turbo blow through. Small block is what I assumed (maybe incorrectly) that you were talking about in your post.

Borrow? Hmmm, can I drive?
