Sorry, i couldn't resist :hihi:

Where are holset numbers? i've been standing next to dyno when they measured 266hp from ATT with diesel fuel wihout any drugs.
 
dont get me rong! it seams that the ATT is a good turbo and all and i understan that there are a few of you hear that sell the ATT and want to make your money but not every one hear has the money to drop $800 on a turbo!

I do have the money but also have a few hx35's laying around the shop from turbo projects we have done in the shop! mostly gasser inports and cant justify spending the money on a ATT when i have theas sitting on the shelf!

now if some one where to show me a flow chart and actual dino resuld of an ATT i might be able to justify it! but in all my serching i can find no info on the ATT!! other than hear say!

so prove your numbers!!

and when i will prove the numbers on the hx35

not trying to start a fight! just trying to find out the TRUTH! trying to find reall numbers!

Pete
 
no one sead it wouldnt work! i know it will work! holsets numbers say so! so in thery it will work well! just have to find a good way to regulate the boost!

might be interesting seeing as i have only ever bilt turbo setups on gasser motors and used BOV's and exturnal wast gates to keep boost where i wanted it!

so the diesel should be interesting!

But nobody is talking shit about anything else. You have the HX35s, so use them. Its probably a better choice for a racer than the ATT. But how much does a NEW HX35 cost and all the parts to make it fit? Can someone without experience and tools hook it up in 2 hours? Looks like a BRAND NEW HX35 knockoff goes for $500 without an elbow with 3" flange, silicone hose to connect to intake or pieces to adapt the oil return.

So before blasting the value of a product please compare apples to apples on what something costs. A new GM turbo costs just as much.

By all means don't spend your money on an ATT, because the HX35 will work fine and you already have them. Not everyone has a used HX35 laying around or wants to mess around for a day trying to adapt it right.
 
if i came acros .................."confrontational"........... i am vary sorry!! it was 1/2 not intended and 1/2 intentional!! i am a member of several forums related to VW, Honda, BMW, and off roading! seeing as that is the croud my shop mostly deals with and in it tends to be when you ask a question all nice like and ask every one over for tie you dont seam to get much of a reply! but being that 95% of us on the sead forums are men we perk up a bit when there is a chaleng put in front of ower faces!

there for there is plenty of replys and info thrown in the ring!

i have posted the same questions and serched! and seeing as this thread is only up for 60 min or so now its got more action than any of my other posts on any forum yet!

and i really do want to see flow charts and dyno numbers!!

hell maybe the ATT would work well on my 2.2l honda! LOL!! i know the HX35 dos!
 
ok so some one posted a dyno print out!!!! what is it a dyno of???? is it a stock truck dyno??????

what was the wether like that day?? what was the temp? come on now more info!! that could be the dyno from my toyota!! looks about the same as the dyno on my 93 toyota 4cyl 22ret

i will freely admit i am new to diesel!!

isnt 195hp stock??????? what is stock HP?? what is stock torque???
 
No one said it would not work, many have used it, problem is for it to not put the engine at risk one has to lower the CR to 18:1, the Holsett has to be modified to fit up, requires inter-cooling to use the high temp air charge fully & is a used turbo until rebuilt.

The ATT is a direct bolt on NEW turbo no lowering of CR required, IC or WMI can be used if you need it, IMO that it is only required if heavy towing or operating in the upper performance envelope, it increases mpg so over time it pays for itself.

If you have fab skills, are willing to live with lowered CR & willing to do the work and access to the Holsett go for it.

ATT vs Holsett in a race, who knows what the result would be, in a tow I'm pretty confident the ATT will hold it's own or surpass the Holsett, thus far with exception of Buddy no one has pushed the performance envelope of what a ATT will do most of us just tow with it or sport on the street with it a little, but ATT is no slouch to be sure.

I'm doing some OBD-II peaking & tweaking stuff myself; it is too soon to know what the end result will be, Buddy has some things going on his rig, couple of others doing some things also, the ATT is relatively new to the 6.5, Holsett has been used with some success, but not enough to warrant the extra work IMO.

What you won't do is direct bolt on a Holsett like you can a ATT , especially on a old engine and have it last boost regulation is not a problem for ATT.

BOV if you think it needs that costs $$$ so more to think about,

Bottom line and a lot of thought went into this, the ATT cost for new is comparable to total cost for Joe Average 6.5 guy to retrofit a used Holsett onto the 6.5,

A number of 6.5 guys do run the Holsett it just requires more work than most are willing to do.

So no crap/smack talking at all, is ATT the best maybe maybe not, is it an affordable solution that gives more power, and anyone with basic wrenching skills can manage most definitely.

We knew :D and this is not to disparage what you have done in the past, when you start talking blow off valves on a Diesel it's a dead give away, no throttle plate slamming shut on a Diesel to worry how much air going to the engine. This crops up when gasser turbo guys 1st delve into turbo Diesel, which is same in some respects but also different.

The 6.5 being IDI and way it's head is clamped down, and some of the block weaknesses there are some pressure limitations to take into consideration when boosting the 6.5.

Welcome to the site, stick around and we can make you very savvy on the GM 6.5 system
 
Everyones threads get attention here in the 6.5 sections, this is the most active 6.5 community for maintenance or performance. You dont have to be abrasive to get information.

Your Holset will run fine, probably even unregulated without a wastegate on a stock motor. I run 20+psi boost on my stock motor, not saying everyone should because it might blow up someday I dont know, and I certainly wouldnt tow anything that way. I might have low compression from blowby that helps, but the engine runs very strong. 20psi on the ATT is hard to get to but if youre there its crazy power, compared to our GM turbos that get there easy at the expense of the engine sounding and feeling weak because of the parasitic and hot turbo. If you have a boost and EGT gauge let it rip.
 
Owner of A-Team Turbo (ATT),,,,, all I can say is wow. If I came in, and did what you did, at one of your other sites, what reaction would I get. We (THE TRUCK STOP) are a little more congenial than that here, along with being a little more seasoned and knowledgeable than most sites regarding the 6.5 Diesel.

Welcome (PETE) Maybe you would be so kind as to post a dyno sheet from an HX-35 Holset turbo and include the ambient temps and barometric conditions associated with your run. That would be mighty nice of you. Stick around we like people that think here: and we entertain a lot, but not incorrigibility.
 
how bout this..someone buy me an att and install it, then in a week someone also buy me a holset and instal it..then in another week i'll tell you which i like best and give the other one away :rofl: :lmao: :hihi:
