so many questions ... get a beer this is long ...
bob , i talked to peirs and we figured i was making to much HP with everything on to get the benifit i was looking for , lower EGT with his turbo . massdiesel has a superturbo on his truck with a 14 housing , it does spool up very quick .
kat , i've got a wastegated 16 4" outlet housing . completely stock out of the box ...
at work i have the majestic screwed up turbo in as many pieces that you can break it down to . majestic sent it back to me this way when i refused to pay their ransome to fix it . they claim my oil is comtaminated and it caused the turbo to fail . thats funny , my original turbo was working fine when i pulled it off , plus i have now had 3 different turbos on my truck since then , 2 with the same oil that supposedly killed that 40 , no problems , my oil pressure is good . if the oil was as bad as they say i would think i'd need a rebuild on my engine . i'm sending a sample of it out just to see what is in there that supposedly killed it . according to my talks with hemidart , they told him the same thing , his oil caused the failure , but they fixed his . which from what i can tell from his posts was still broken when he put it back on . one thing i noticed with a couple other turbos vs the majestic modified unit was when i put oil in the top it didn't take more than a minute for it to come out the drain side , on the stock hx40 and a piers unit it took over 5 minutes to see it go down from being flush with the top of the boss that the oil line fitting screws into . also the 40 that broke had such a whine and an incredible amount of lag compared to this one .
ok on to more questions ...
kat mine is set to open fully at 40 psi , it begins to open at 20psi , it comes from holset set this way and the adjuster is peened the same as the dodge unit . i'm going to give piers a ring and ask him about setting it , i have one that has the peen defeated and can be adjusted . top end is very good , as is the midrange , it doesn't spool as quickly as my 35 w/12 , but it piulls stronger with less boost . speaking of boost , once it begins to spool up it will hit the max boost , highest i have seen is 40 , at alot less throttle than the 35 , half throttle gets it to 35 and then some , except for the whine this thing kicks a$$ .
work2much , i'll make note of where it starts to build boost tomorrow plus i'll get a chance to see how it tows , i'm renting a bobcat and towing it to and from the rental place .
it peaks at 40 but for some bizarre reason it drops back to 30 quickly , i wonder if it has something to do wit hthe wastegate being open early ? i'm goign to pop on my bleed elbow in the AM and see if it affects it any ?
this is with the dd3's and hot pe only , no EZ , i just bought one off a member that sold his truck , i'll have it next week and be back at peak hp , i am going to try to hit a dragstrip when i go to maryland this weekend , borrow an EZ and see what i get for a time , should be a 13 , as long as i figure out my no 2-3 WOT shift before then ...
miker interesting note on egt wit hthe kwikspool , from what i could tell it was lower than a 35/12 , but not as good as a 4" oulet 40 housing , i may have to get one to try out , but for now the big plus is no more 1500* banzi runs , for now ...
