Ordered some parts...

[AH64ID]

No its not, and I have only seen over 1:1 that one time, everything else is pegged on 1:1, or within a couple lbs.

Can you replicate at will? Under a load and over 2500 rpms I am always at 1 to 1. 3-5 depending on throttle position. Unloaded its much less but still a spike starting at 2500.

 

[AH64ID]

I haven't tried to be honest, I am rarely over 2400 rpms its just not how I drive.

Stock was 1. 5:1 cruising and this is dead on 1:1, or under I have seen . 8:1 at slow speeds!

First tow is today, and then a weekend trip this weekend, I can't wait to see how it does.

I'd be curious to see what the drive pressure is on the front cylinders without the waste gate. You're measuring EGT on the wastegated cylinders, how much higher would it be on the non-wastegated cylinders?

 

[AH64ID]

I measure DP on the front cylinder, so I will be able to see it if it drops when the WG opens. I have yet to hit the boost required to open it. But I bet it drops nearly the same as the aft bank. It's pretty much 1:1 or better in all the driving I have done so far.

I honestly don't think EGT's will be effected by the WG location during WG operation. But I don't intend to spend much time at all in the 35-37 psi range, so I am not sure it will be an issue regardless.

I got the turbo from Pat at Big Twin in Meridian, but I believe he uses Tom as his Garrett supplier.



I won't make the dyno, I have drill that weekend. I do want to dyno the truck with the new goodies and see how it does.

Bummer you won't make it, was hoping to meet you & check out the turbo



I was in your neck of the woods today, had to make a quick dash to Boise but it was a straight there & back type thing.
