Boost fooling....hmm do a search as well but here goes my 2 cents.

The Edge Juice fools the computer into thinking there is less boost so it makes the turbo put out a few more psi. (32psi is stock) More boost allows lower EGT's and increased power in the upper rpm. However, too much boost on a stock turbo is bad because its out of the efficiency range of the turbo. IMO above 45psi is excessive on a stock turbo.

and for future reference.....the Attitude monitor does not read boost accurately since it is reading the fooled number from the ECM

 

Simple enough - thanks! The highest I've ever seen is 40, and only once. The norm high is 37 and usally mid to low 30s.

I called the dealer a couple days ago to ask what the max PSI is on the stock turbo. The service writer said he thought it was 17 PSI. I said no, I think it's a little higher. I see that number everytime I leave a stop sign under normal acceleration. He said he'd go ask a tech and came back a minute later and said it should be 60 PSI.

 

Hey Lark, whats goin on. Does your dealer know anything bout this truck?? Not to sound smart or anything, but if he would look anything over 45-50 psi in the aftermarket they reconmend head studs. So 60 would probly blow the head gasket alot. I think 17 is right around for a d-max but not the dodge. I think the stocker is good for 35psi and people on here said that 42 or so on the stocker and the blades explode. If you go to ats they have a chart for the stocker vs theirs. I was goin toward twins but think just the 3k will be good for me now.

 

The stock turbo doesn't like that high of boost, it won't last long running that high. I personaly think the intercooler is a wast of money, they just don't make a huge differance on anything under 55 psi of boost. The stock intercooler dose a great job and I would stick to that. As for dual turbos they are great if you have the money to get the kit. But for the power you are wanting to make a single will get you there for alot less work and money. Do go for the attitude with the hot unlocked. A buddy of mine has that with a set of 3 flow injectors and a super 62 and loves it, the turbo spools great and has killer topend. So a BD single ( I think its the super b special thats the bigger one) would do you fine if you want to go with BD.

 

The hot juice works great. With the 6280 I can get 55 psi, and managable egt's

The edge is fooling the factory computer from setting an overboost code and defueling the truck, hence calling it boostfooling. At I think its around 27 psi give or take it will defuel, and thats no fun especially when your winning till that happens a the ford passes you like you standing still. Ya dont ask!!!! I had to have a few drinks after that.

 

I agree completely. Forget about the IC until you have a turbo or if you want to drop 4-5k in a set of twins do that. But if you just like spending $ get the IC and a set of twins.

With only 450-500 in mind a 6270 or 6280 should be just right especially if driveability is an issue.

 

brock and guys, thanks for the honest opinions - I'm going to go with y'alls recommendations.

However, I'm going insane with these numbers. Is a 6280 or 6270 a brand name of a turbo (I've seen it mentioned on the forum like a million times but don't have much luck when I Google it), or is it a "style" of turbo? I'm assuming it's not the BD Super 62 as people seem to compare the two???

And brock, you just recommended the Super 62 Special (which is bigger than the Super 62 Single). I was under the impression that's a really BIG turbo and would I not loose performance for regular driving (long spool up times)? I'd rather have a really nice PUNCH while regular driving than have crappy regular driving and more power for racing (I don't plan on drag racing the truck). Does that make sense?

Thanks again for being patient with me, all this is new and it's starting to make sense.

 

I'm listening also...

 

The 6280 is made by Industrial Injection (sometimes reffered too as II) It is a 62 14 size. High Tech turbos also make a turbo that size. BD's turbos are called super b and such. ATS use the Aurora nomenclature.

Also when talking about the super, that is another II name, also the silver series. These refer to the size of the shaft.

The first number ie 62 is the size of the inducer in mm. The second number ie 14 is the size of the exhaust housing in cm^2.

If a 70 is used or 80 or what have you it is the area over the radious or A/R and is a .70 or .80.

The lower the numbers the faster the spool but the faster they will build heat.


And I am still learnin this stuff too, but if you spend enough time lookin at differant turbos tryin to pick the perfect one some of this info is bound to stick.

 

The iis 6280 is a great turbo but the super 62 is better with more topend and lower egts. The guys at IIS will tell you a silver 62 is the best turbo to use but they are so slow to spool up. That its not a good all around turbo, also if you wanted the silver 62 why not go for a silver bullet 66, they spool almost the same. Htt make a 62 that is a awsome turbo as well. For what you want I would recommend a 62 super. So yes the 6280 is a model of turbo.

 

brock, u sure you don't work for BD? LOL

I called them this morning and was told almost exactly what you told me. They said the Super 62 Single does not spool any faster than stock, but makes a lot more power and will run all day in the 40's. He did not recommend the Special since it's too big for what I'm wanting - too much lag unless you have the fuel to support it.

I also asked about the intercooler and again he said the same as you (and others have said). He said it's not really needed for my application, but it would certainly help. He said the stock one looses about 4 psi and their looses 1 psi, but it's great for lowering the EGTs. Maybe that's a good thing here in north Texas where it's so HOT and HUMID in the summers???

So, here's my drawing board...

BD Super 62 Single
BD Cool-It Intercooler
Torque Converter upgrade
Valve Body upgrade
Attitude with HOT setting (to be added to my Edge Juice)
* what do I need to do about fueling??? *
BD Twin Turbo setting later down the road...

The guy at BD swore this setup (single turbo) would give my current truck the difference between night and day. Agreed?

 

brock, in your opinion how does the spool of the Silver 62 compare to the SPS66? What about the SPS66 to the SB?

How about top end and EGTs?

 

After researching and emailing back and forth with II, I'm going with a Silver62. With all these guys running larger turbos on the street, I don't think a little lag would bother me, especially if I'm after 600-700hp...
