Just think how well it'll run when ya wash the "grime" off and drop all that weight!
Great to her it's up to snuff. KM

Just a small update for you guys.

I am just drooling over the spooling noise from these turbos. The stock 2.7 turbos are actually pretty quiet.

I gave the gas pedal, 64% and this baby cranked out 41.4 lb/min (I was only getting 31-32 lb/min on the same tune with stock turbos)

At 5800 rpm it’s making 18 psi on this tune. Quite a huge difference since on the stock turbos it was making 8 or 9 psi at redline.

Sending the log off to Brett. Let’s see what he can do!


(Also, I’m like the only guy who has done anything like this on the 2.7L on the forums right?)

Impressed with your rate of progress and tenacity. Excited for you man! Can’t wait to see where this goes. [emoji897]

Thanks! Me too!

Another update… took it for a drive tonight, it punched out 43.2 lb/min with 70% throttle and from about 3000 rpm to 5800 rpm it’s holding around 20 psi solid. I never saw boost go lower than 18.9 psi during the pull.

so I guess my next question is, how much will this thing do?

R U sure the stock turbos only make 9 psi boost ? My completely stock 3.5 makes 15, not tuned.

No no no, I’m talking about at redline rpm. The stock turbos were making almost 21 psi at 2900-4000 rpm

 

[Arkansas Eco]

OK that makes more sense LOL

 

[boostkingMatt]

Yeah. Let me be more specific now that I’ve done some logs,
Stock turbos were around 7-9 psi at 6200 rpm
Stage 2 turbos are at 15-17 psi at 6200 rpm
But they are still blowing 20 psi at 5500-5800 rpm which is nuts.

 

[boostkingMatt]

Couple more things I want to mention…

First of all, the audible knock that you guys have heard me talk about non stop for the past few months is gone.
What actually was causing it?
The seals in the stock turbos were going bad and leaking lots of oil Into the charge pipes.

Also, I absolutely love the way this truck drives now. It doesn’t feel like it’s lost it’s low end torque, but it noticeably spools up slower. I wouldn’t say they have lag necessarily, because I still have good torque, but boost doesn’t really start kicking in till around 2500 rpm. It takes like .20 - 1 psi to get off the line decently whereas before it would take 3 or 4 psi. Power and boost is later on in the rpm range, and I really like that, because the truck drives like a normal truck, but if you step on it, the power and torque come on gradually till it sets you in the seat very hard. I really like it. Ok, I’ll shut up now. I’ll post more updates as the tuning goes forward.

The loss of low end is my reservation on bigger turbos. But I’m glad you made the distinction between “turbo lag” and availability of torque.

I’m fine moving the torque curve up in the range a bit as long as it’s linear.

What I don’t want is a WRX-style turbo on/off switch via throttle.

Yeah, the truck gets off the line just as hard as it did before, if not harder, but it doesn’t spool up fully till much later in the rpm range. My old turbos would be already very spooled up off the line. I really dig it though, because later “full spool” means more power up top and more mid range power. It was very lacking in top end power before. My old turbos kinda crapped out in high rpm.

Matt,

Just because it's not full spool doesn't mean the new turbos aren't pushing the same amount of air. Does that make sense?

Matt,

Yeah, you’re right. It’s kinda complicated to explain. I’m just saying that these turbos are in vacuum at times when my old turbos were in boost. It’s just amazing. My stock turbos were fully spooled at 2200 rpm, but these aren’t fully spooled till like I wanna say 3000 rpm. But before it gets to 3000 rpm, the power doesn’t feel less than the stock turbos it actually feels even more powerful. Also, the truck doesn’t fall on its face after 4700 rpm. It just keeps pulling hard all they way to 6200 rpm. Quite amazing.
