Turbo question
 

Would that work well with your 150s and the Edge Comp I've got??:humm:

62/68 would work well

63/68 would give you a little room to grow.

Well I don't want it to be slow to spool but I also don't want an EGT problem. I don't have a problem with a water meth kit if that's needed to cool it down. I'm thinking down the road a Smarty would be nice to have for the low end power and spool.:humm:

a 62 would be perfect and put you at 500hp at least and a smarty is a chunk of change to loose hp with.

As for the Smarty, I really like mine. I pretty much leave it on level 1 (Economy) and my Edge off. Makes it an excellent daily driver.

Sup,

I am running a Smarty with the original software. I had the revo, but went back to the original. I just went to Knoxville a couple of weeks ago and Running the Smarty on 4 and the Edge Juice on 3x5 I hand calculated 17. something for mpgs. On the trip back to Maryland, I changed the Edge Juice to 4x2 and my mileage went to 22mpg. I tried to keep 65-70mph on the way down and then I ran 65-75 the majority of the way back. Got to play around with a 3rd Gen Dually and we blew some soot and I remember at on point after a WOT run I was coming off of 90 something and the boost was about 26 as I was shutting her down to get back on track for my mileage. I am running a Super B Special and a set of 175hp injectors. So With my setup I am pretty glad that I had picked up a used Smarty.....Any way just thought I would throw out my .02.

I get that mileage with just a comp box

01quadcab,

Did you get that mileage when you were making the 11-12 sec passes? What size turbo were you running at that time. It seems that my mileage has been like a roller coaster as I have changed out different injectors and such. The TQ management has been a real pain and the Smarty has helped me alot. I would not buy one brand new for sure and it was not the first thing that I invested in. But it was a nice add on feature for me later on though.....:tu:

If you can get you hands on a Big changer, S400 or so, you could do you own compound turbo set up. I got my S400 for free, and everything else cost me $700 to get it all together. I have lots of boost, and it is good and cold. I can't break 1200* EGT with any, or both of the chips maxed.

Yeah I was running some lightning III injectors and a 62 over a 475 drove from ca-ks-ca raced at the world finals in topeka and drove it home. it's all in staying constant cruise control is your friend.

Well what I really like about the Smarty is the low end torque they add. Right now I made 411 hp with my current setup. I'd like to be in the 500 hp area with EGTs under control. Trying to weight the advantages of the SE single vs twins.:humm:

Turbo question
 

This makes me wonder why I can still hit 1550* with my 62/s475 setup

add more fuel you don't have enough. I ran 200's with same turbo at first and they worked well low egt's even the 240's were decent egt's. I don't think 150's are near enough fuel because the work pretty well with a single 62.

BIG DAWG 250's :rocking:

Turbo question
 

I wouldn't think going with a bigger injector would drop my egts by like 300 degrees haha. I was thinking water meth

you would be surprised how warm under fueled truck will be just like an over fueled truck. I had ddp 200 240's and lightning III's with this turbo setup and could drive them all around town etc. with the 200's I don't think going down the track it went over 1300 with 240's would hit 1400 and the l3's were a little too much fuel. 575hp 603hp and 683hp all on same dyno

Turbo question
 

It's not only even at WOT that it bothers me. In overdrive 65 mph up slight hills on the highway no load I have to keep it very light on the foot or it breaks 1000* just cruising. Passing people on the highway not even hard on the throttle I can get 1200 very easily. Otherwise flat ground 65-70 mph cruising runs 750-800

Ever think about getting a 3 piece manifold?

Turbo question
 

Yeah. I'm running the stock manifold with my compounds. I would hate to rip all that back out to put a 3 piece manifold on. I hear they don't matter much anyway. I may just do water meth. I'm a dealer for snow, so 500 bucks and it's fixed for sure

whats your rpm at when your doing this? Sounds to me like large exhaust housing on your turbo or turbos. it's not spooling I went from a 1.32 to a 1.10 on my 475 and that made daily driving nice and I lost nothing for power

Turbo question
 

Just cruising like 2100-2200 rpm... The top is a 62/14 I'm not sure what exh wheel is on the 475. Doesn't really feel like it's spoiling as fast as it should. Real smoky at low rpm till spool. Once they light tho hold on for the ride. Wastegate has a clamp holding the line shut right now and it runs 54 55 psi WOT. That's edge juice on hot unlock, 150hp big dawgs, and hotrod vp. Sounds to me like it could use more fuel, but to be honest I like how it runs with the EJ on lvl 3. It's MUCH smoother at WOT than on 6. Lvl 6 has rpm and boost fluctuations at WOT.

the top turbo has a laggy housing as did mine, I bet your 475 is the 1.32 ar too. I bet on level 6 when your boost fluctuates your gate is opening and will make it drive crazy. I ran mine with no gates made 85 psi down the track. more fuel or smaller housing will help

Turbo question
 

Yeah. You might not have caught in that last post that's 55 psi lvl 6 with the gate hose clamped off. I clear all my smoke at WOT also so I know I can use more fuel. I just don't understand why it would run cooler... There a guy on YouTube I found with my exact setup running 200ddp's and he can't break 1230 degrees. Weird

I didn't read the correct then yeah you need fuel because that should be making more boost. I believe they run cooler because you actually have the fuel to spool the turbos and make them efficient. you could also drop to less bottom turbo too but I think sticks are a lil cheaper and less work. I would also do a 3 piece manifold because the stock ones like to crack and it's possible you already have some cracks

Turbo question
 

Ddp 200's or big dawg 200-250 possibly. Or just do water meth and it'll drop the egts for sure...

I guess to me Im not a fan of the water meth due to the fact its not maintenance free. What I mean is its not like sticks drop them in one time and forget about them. Whereas the water/meth is like a propane bbq its nice when there full but your always going back to the store for a refill. Kinda get what I mean.

I agree sticks are less maintenance and water can always be added. I would get ddp 200's myself I ran them with my single for a month because I was doing compounds next and they were a little much for the 62.

Turbo question
 

Think 250s are too big?

I think the 200's are better for daily driving etc. less lag time etc. I would go with a quality injector like ddp or mach

Our Big Dawg 200's would work good with your setup.
