LLY: PPE compounds

[PACougar]

It's with industrials new type of injector, something different with the body's.

The whole point of injector flow being measured by percentage over stock is you can directly compare them. Regardless of what might be done to an injector 30% over is 30% over. Asumming the manufacturer is acurate in their claim 130% injector is less than a 200% injector.

I understand that, not trying to argue just stating the facts that I heard. They are a new type of injector not available on the market yet. They also have to be tuned differently iirc. Custom auto put them in their blue truck and it was backfiring on the dyno cause they couldn't tune them right.

Ok so this is what I got. Top 3300us. Mid 1800-2300us. Low from idle 415-550us.

That's a lot of pulse width. Howuch timing is he running? I would suggest bigger injectors. Have you guys logged rail pressure?

 

[snowman]

Rail pressure is good. Doesn't drop. 29 degrees on the top.

 

[ThebigGids]

Bigger injectors will probably clean that smoke up...plus make it safer on the motor and reduce egts...

 

[snowman]

The egts didn't go over 1200*. But a bigger injector will clean it up that much?? How about the lag??

Should help with both lag and smoke. Faster those turbos light the quicker the smoke goes away

Who's tuning also?

 

[PACougar]

I would also suggest going with a vendor that sells Exergy injectors. They are by far the cleanest running most balanced injectors I've had so far.

 

[snowman]

Ya I was thinking of exergy injectors. Well probably go with those. Tuning is done in house. This is the first compound truck we've done.

The bottom end will thank you!

Get bigger injectors.

What rail pressure are you running, I know you said its good but what psi are you running? 28k? 23k?

 

[snowman]

Rail holds at 26,000psi.

We're thinking the a/r might be to big on the high pressure turbo. It has a 1.09 a/r. Thoughts??

 

[snowman]

Sorry a/r is 1.06 on the 4094.

Probably because Dmitri was trying to tune it... :rofl:

 

[hondarider552]

What is the turbine wheel size on the little turbo?

 

[LBZrcks]

Try better tunning. I have this same kit except with a GTX instead of GT. They spool fast with very little smoke. I have 60 over Socal/Exergy's and stock 130k mile cp3. Haven't dyno'd this setup, but I only race on a smaller tune just over 2200us I see around 55psi and consistent 7.5x in the 1/8th mile

 

[LBZrcks]

What's your drive pressure, and how's the wastegate setup?

 

[snowman]

What is the turbine wheel size on the little turbo?

Turbine wheel is 77mm

 

[snowman]

We haven't thrown a gauge on the drive pressure yet. The wastegate set up is just how it came from PPE. Off the pedestal of the high pressure to the pipe driving the atmosphere charger.
