Stole this from a thread started on CompD.

Simply amazing.

Notice the hose clamps holding the charge air piping together, the motor must not have needed much boost.

Whoop whoop for the small wonder Delaware lol:woott:

Man,that's cool and seriously impressive for the era:thumb:
And what is the current record?

6.35sec @ 218mph by scheid diesel dragster...wow, that's insane

Srsly though, in 30 years time, that's it, 1.4 seconds improvement....:baby:

I see a blower on that 2 stroke monster!

 

[SmokeShow]

Dang impressive!

1800hp with 270 cubic inches

ALL DETROIT diesels had blowers, that was how they ran. The intake was ports in the cylinder walls, and it had exhaust valves. It didn't use the crankcase to pressurize the intake charge, but instead a roots type blower. The high HP ones had a valve that actually bypassed the blower at higher boost levels, and used just the turbo to blow the air charge in.

7.21 to 6.35 is not 1.4 seconds...its 8.6 tenths as in .086 seconds :thumb:

Its accually 318 CI. that was a misprint, but very respectable reguardless.

Did you read where it was de-stroked?

No he did not read where it was destroked to turn more rpms lol

I wonder how that valve would work on our compound setups?

I've often wondered why nobody has tried it yet. On the DETROITS it made a big difference to let them breathe better in the upper RPM's and higher boost. JOHNSON & TOWERS used a lot of them on the higher HP DETROITS they did like the 435HP+ 8V53's.

I've wondered the same also. I believe the 6.4 PSD use a similar valve to bypass the smaller charger. It would be fairly straight forward to Y a tube from the atmospheric charger straight to the hotside pipe with a butterfly valve in it that uses boost pressure to open. I THINK..............

I have wandered about just compounding the exhaust side, but not the air.......

I get my ally parts from johnson towers I will ask them on valves maybe do some testing.
