Injector relocate

Very similar to the set up I use on my cfi1000.
Flanges are separate and a one piece fuel and injector rail
mounted on top. Built by Brad at PAR. It's nice to have lubed up reeds again.

Agree on the lube. That would have been an option for the Cat TB. Now with an electric oil pump on the AXYS the AC bodies may work. They are also larger.

MTNTK's Axys turbo kit uses a 3D printed injector manifold that goes upstream of the throttle bodies.

3D printing is going to go a long way.

Oil

Can also ditch the oil injection with this setup.

We have a 3D printer at the house. If you need something drawn up in solidworks or printed out, talk to Val. She can get it done for you.

Worked on building a fuel rail again today. Second go, the first one had damper interference issues. Will post a pic when it's done.

Thanks Murph and Val. If this works maybe that would be the way to build these instead of billet.

It's hard to contain my excitement over this...even at 03:17 in the am...

Don't overdue that foot injury brother...

TRS · May 10, 2016

Almost there.

TRS · May 10, 2016

Bolted it up on an engine on the bench. Looks like I can finish it.
Hope to get it on the long rod shortly.
I decided to go with an external FPR from Cutler.

Will you be able to pilot this when it runs depending on snow or will your foot keep you from riding it?

I'm liking it more. I want to redo my intake setup on my turbo and may opt for this since I really would feel better about the engine longevity.

Hope to test it when the road opens in the Beartooth's. We can Bluetooth DW to get a feel for what's going on.
Doc and my bride won't let me pilot it so I'll get Justin. If not I'll fire up the Dyno.

If we can work in mine at the same time, I will come out and assist. :face-icon-small-coo I know I am not the Justin you were talking about. Shoot I would just like to be there to learn.

Tony of you get hurt again there may be another sled manufacturing company.

tony thats a bunch of trophies in the background :face-icon-small-hap keep up the good work

Thanks, I forgot about them up there.
Yea, we won our share of WSSA State championships back in the day.

nice :face-icon-small-win

I've asked TJ Krob, engineer and great guy from Dyno Jet (Power Commander) to chime in here too.

Great thread.

Definitely prefer to keep as many stock parts and settings as possible.
With that said, a fuel controller may be needed. Also looking at a larger set of injectors which will force an injector harness build. Darn epoxy.
Thoughts of an external FPR, maybe a rising rate with the signal from the pipe.
Going to install this on my '12 LR. The Dyno will come into play for testing this summer.
A timing key may also come into play.........

Click to expand...

Connectors and pins are easily available for this... on both ends of the injector harness.
I think that a rising rate FPR could prove to be a bit unruly and not consistent with a "stock as possible" goal for this N.A. sled.
I am a fan of a more precise FPR than the inexpensive Seimens 'tophat' mini FPR that comes built into the stock PFA.
Lots of factors to play with... Maybe the PC-5 with timing control would come in handy??

THIS is a very cool build thread!!! Great work there Tony...
Swapping the injectors to the opposite cylinder is very creative and should help keep the mechanics of an engine designed as a sequentially fired mill wrapped up nicely. We've always hated blowing hot air at un-lubed reeds - which this is a perfect solution.... My '12 Pro (shown here) liked seeing 11.8:1 at 9PSI on stock injectors running 50/50 AV/91 - just goes to show that bung placement, sensor condition, and turbo setup can lead to very differing readings from one sled to the next!

At first thought, and as MH eluded to, the extra saturation of fuel through the entire case/combustion chamber may enable some drastic changes to ignition timing which the PCV-CDI can deliver for you .... +/- 20* if needed to obtain the most performance out of the newly directed fuel charge. Plus, if you swap to i.e.: 30% larger injectors, we can offset the fuel map with a -30% to keep idle and part throttle performance in check during stratified charge conditions.

Very cool! Can't wait to see what your testing reveals....

Thanks TJ. Will keep everyone posted as we move forward.

TRS · May 16, 2016

Just to keep this TTT. I received the FPR and plug today from CMX. Thanks Mark.

Thanks Roundy, We will give it a try.
