Jaw Dropping Damage to FED Dragster - btw she's already runn

[archaeicbloke]

I figured i just HAD to share this with everyone....

Rob finally posted pics of the blown up engine and bits here: http://skyline-life.blogspot.com/2011/0 ... -done.html

Not very often you get a real look at what a massive amount of horse power can do to an engine... It's turned that rod into something that resembles silly puddy!

Even more impressive though is that less than a week later, he's already got the engine rebuilt, and running again, this time he's testing out some new technology to make even MORE POWER!...

Rob's got some sort of power demon inside him thats trying to escape it seems... un-real the work he does....un... real.... :O

For anyone who hasn't seen it yet, you can check out the whole story from birth, to world records, to destruction, and rebirth here: http://skyline-life3.blogspot.com/p/fed ... acing.html


a couple photos for y'all but theres more on the site!

Rob's got some sort of pow.............

Please Excuse this part, I misread the post, as someone pointed out to me the engine was rebuilt quickly so he could get to the races on time, and the CO2 injection is to help the turbo spool quicker, may not necessarily be "More Power"... I don't know for sure, but we can hope! lol

again, Very Sorry for any confusion this may have caused

Lets see that engine in a skyline

it was way cooler in the s30.

[tigersharkdude]

did a really throw an entire piston through the side of the block?

[archaeicbloke]

not too sure? but this picture may be of some indication...

Are they pre-heating the C0-2 at all? I wonder where they're injecting it at? I'd be worried about thermal shock to the turbine blades.

[archaeicbloke]

Hey Float, I think I read somewhere on one of robbie's posts he said he was running it at 800 PSI no? post a comment up on the thread and ask him!, curious to see what he says! lol

[PapaSmurf2k3]

800 PSI is right about where CO2 will remain liquid at normal atmospheric temperatures... so I believe it.
I dunno, usually you run CO2 just to cool the intake charge (like purge a butt ton at once just in front of the intercooler), not inject it directly into the air stream.

[float_6969]

They're injecting it into the TURBINE housing, pre-turbine blades. I've heard of a similar concept in other applications, but it was plain air, and the jet was aimed at a particular angle directly at the turbine blades.

My concern with this was that the temp of the CO2 is going to be VERY cold, even inside the turbine housing, and if they're spraying it directly onto the turbine blades, I would be afraid of the blades cooling down suddenly and shattering.

I'll post a comment and see what he says.

[PapaSmurf2k3]

You could probably run the line through a heat exchanger first to warm it up... but even at that rate, it would still be ambient.

[float_6969]

That's exactly what I was thinking. The application I saw it in was for an airplane IIRC, but they were using compressed air and a pre-heater that was heated by the exhaust gas. IIRC it was on an airplane, but don't quote me on that. I read that a LONG time ago.

If you injected it closer to the engine, I think the CO2 would have time to warm up enough to prevent thermal shock, but I wonder what effect it has on the exhaust manifold pressure compared to the intake manifold pressure and if that would cause problems with reversion, thereby contaminating the combustion chamber.

I'm not saying this won't work BTW, only speculating as to the pros and cons.

[PapaSmurf2k3]

You know, they DO have vacuum cylinders that use compressed air to generate vacuum. Kinda like a Venturi cylinder. Maybe the air is being injected just after the turbine, which pushes a velocity profile down the exhaust, sucking air in through the turbine? I'm not even sure if that would work, seeing as how its more or less a closed system (with an ICE anyway... I could see how it would work on an airplane turbine).

[float_6969]

Yea, I could see it working post turbine, but you'd have to have it near the end of the exhaust and it would have to have a specifically designed venturi, but that would definitely work. Depending on the length of the exhaust, they're might be a little lag, but on airplanes/drag cars it wouldn't have much effect as they both have very short exhaust paths. That would eliminate the possibility of thermal shock to the turbine or manifold (I thought about the manifold later.
