Anyone check out PDM Racing's KA-T?

Looks like a super nice ride. 295whp at only 8.8 PSI!! Looks like they will be doing custom tunes. Here's the link.

Man that piping is the best part! What do they mean by 'back filling with argon'?

looks nice!

I think it is to smooth out the welds on the inside.

Nice car...Anyone read on page 4 about misting water on intercooler with c02 to form ice?

[hannibal]

295whp from 370cc injectors, hmmm...

[slipnfall]

Yeah I read that part, and I know the argon is used to keep oxygen away from the metals while welding - just never heard of the term 'back-fill', like they pumped argon inside the pipe while welding also?

[slipnfall]

Like they say, it's all in the tune... I wonder if they're going to start offering pre-canned/off-the-shelf tunes...

i have to say that the best thing of that engine bay is the AICV plumbing..........ive never thought about using ss fittings and a line but man does that look neat.

damn those welds like look it was done by robots, its sooo damn smooth. also its crazy that he had his T04B being oil and water cooled. doesn't that mean its a ball bearing turbo? i never knew they made ball bearing T04B's.

D'oh.

Marc, do you know if they are planning to market their ECU tunes?

[jmwenick]

Whoops, well it looks like I wasn't the only one who didn't see that.

[Repo Man]

I've always thought PDM was pretty squared-away. I wish they were a sponsor.

[nismofly]

the car simply rocks, no two ways about it

I have no clue...I'd hope so though.

Since the days I first started doing business with them well over 3 years ago they've expanded QUITE a bit and have offered a lot more stuff for the 240sx...they were originally the ONLY company who offered aftermarket cams; now they offer billet turbo and N/A camshaft applications, etc. They're definitely growing, but this is their first tinkering with the turbo 240 (although not with t/c cars)...

The reason I respect Don so much is that he's an actual race car driver, and a damn good one at that. And by race car, I don't meana drag race car that can't even be driven off the track, because I firmly believe that's the lowest form of racing there is...I mean road-course and auto-x.

Anyway, you could definitely give 'em a call and ask them that; they've always been very nice and helpful in answering questiions.

What they are talking about with the back gas filling is somthing that is commonly reffered to as back gas purging. When you weld you create an electric arc between the two pieces of metal and then fill that in with the wire or rod. In order to prevent metal splatter, burning, and overall produce a cleaner weld you need to shield the weld from the atmosphere by blowing an inert gas on the weld. This is usually a CO2, Argon, or Nitrogen gas or a mix of two or more of them. When you back gas purge you also flow the inert gas through the piping you are welding to ensure that the weld stays clean and pretty on the inside of the piping too. You just need to tape the ends off on the piping and poke a hole in each side the air goes in one side and flows out the other side.
