How much power can the stock bottom end handle?

[Black GT]

I know it is a forged bottom end, but how much can it handle?

 

[HHGT]

1000

I think Ray is testing that right now :biggrin

When we were in Indy and talked with the boys from the Romeo plant they did say "stock bottom end and stock fuel delivery is good up to 1000hp - just keep it under 6500RPM"

 

[dbk]

The block won't warp until you're over 1400 hp.

I doubt there'll ever be a time in history at which we can't count the number of GT's that attempt this on our hands.

About to hit 31000 miles on my car stone stock bottom end.

 

[BlackICE]

If your drive like Pockets, the bottom end can take unlimited power! :lol

Ft-Lb Rating Bottom End

I know it is a forged bottom end, but how much can it handle?

I had heard rumors the bottom end could handle close to 2,000 ft-lbs, but that seems a little high as I think about it.

 

[kumar]

did Joe Piko ever break something on his bottom end or did he build it up just to be on the safe side?

Crankshaft

I think he was over 1,400 rwhp at the time and then was adding a shot on top of that.

 

[kumar]

well Ray's blue car just made over 1350rwhp

i wonder if he did anything to the bottom end

 

[MAD IN NC]

I think he was over 1,400 rwhp at the time and then was adding a shot on top of that.

There was a forging problemm in that crank that failed - not the engine's or drivers fault. Car is still the same w/ over 1,250 capable of going over 1,450! It does have:

- Carrillo Rods, CP Pistons 9:0.1
​

Fuel Syestem is:
- 4 in-tank fuel pumps
- 2 stock pumps
- 2, 342 lph pumps
- 2, pumps per fuel rail
- Custom Fuel rails are
- 8an fuel feed lines from
-16, 63lb Precision Fuel

Peak Performance:
- Horsepower: 1,453 WHP
- Torque: 1,250 WTQ​

:biggrin

hmmm now Im curious how much one can push the power levels if they were to upgrade the fuel and clutch.

You thinking about going for the record?

 

[kumar]

Nah Im just curious for the future. Im aiming for 1000rw or maybe close to what Torrie has.

But Im wondering if you could get 1250-1300 by just doing heads, fuel, etc and not touching the bottom end. That would be pretty incredible. I cant think of another car that can handle that kind of power on a stock bottom end.

 

[Silverbullitt]

The major thing stopping me is the life expectancy graph. I rode in Joe's car once. I guess you wouldn't feel it if things went wrong.

 

[tmcphail]

1000-1100 is do-able. Beyond that the life expectancy degrades at a much faster rate. Just depends on how long you want to or not want to bank on a full bottom end.

so at that point you would do pistons, rods, and a cryotreated crank?

maybe valve springs/retainers?

 

[tmcphail]

That would be the safe bet.
