Figured I would show off the art since not just anyone has one. Light enough to curl like a dumbbell.
 
Yessir. Looking forward to mine being put together and watching the yours run at some point. Why did the rail get its current name?
 
G.M. Performance Parts is once again giving me support in drag racing and land speed racing with the Chevy Cruze Diesel . I raced under the G.M Performance parts banner for 4 years in my competition eliminator D/ED


Here is me at the NHRA world finals in Pomona in 2000

For those who are asking about the ECM, I thought I saw on Greg Fbook page that Dan's Diesel is doing the tuning.

Congrats Greg and awesome looking rail!

Looks good. Is that not Coan's 10.5" billet spragless piece? I've been spec'ing out another build and Coan agree'ed that convertor would still not work with my setup. It can't be tightened up to work in the efficency range of say 3k-5500. It's concidered a 5k+ stall unit
 
Why aren't you using the aluminum block you were touting all over these pages?
And what ecm?
Is johnboy doing the tuning?

its fast , I have run it down the track in to different programs and it was fast both times. and yes it stalls close to 5000 but that is what it takes to get smoothly down the track.

The new CN block and billet head are winter project, I can make plenty of power for now.

the ECM is a factory ECM G.M. sent me a stack of them , and yes JohnBoy is tuning my car.
Dan and I are working together on several 2.6 programs and he has offered to help tune, but I have been working with JohnBoy for a long time.

All was good til the last page. The hand has reached the back now. That is enough reading in this thread for me.
 
Greg that first photo of the dragester how long ago was that taken?

It appears to be missing a few things to be (almost running).
 
The engine with complete dry sump and under driven cam driven twin CP3’s is on the engine stand at D&L while I worked on wiring and plumbing. It’s a 1 hour job to install or change motors in the car.
I my go on the dyno, one more time before we go down the track.

The car is completely wired and plumbed except 2 gauges that should show up today I have a new digital dash as well from RPM performance Data loggers that is being released in a month or so.

its been back to Coan a few times over the years , I have a few other convertors as well , but thew Coan is by far the most efficent .
 
Besides the dr. p truck what else has it been in? Data may have shown other wise but it sounded like it sliped very bad in that truck down track, didnt even hear the gear changes. Again I hope it works great for you for sure, you have a better chance of doing so w/ a d max rather than a 12v. All 3 oem brands have and still use a 13" l/u convertor and when those guys loss thier clutches in the l/u thier back to a fluid coupling design, and from what most say they suffer greatly when thier gone. I proved to myself that the fc design can be made much more efficent in a low stall speed unit in a high torque 12v but soon as I loosened it up to spool larger turbos the efficency went out the window again even being 13". And when I say loosened it up I'm meaning anything past 3k for sure. Remember also how Scotts and John's cars sounded down track with a small converter and glide simular to the dr p truck; like they were hung against the governer and the engine didnt pull down at the shifts, this isnt taking anything away from them but only suggesting there was pleanty left in them If locked up.
