Competition Blew up my DD Jammer turbo

[Swayse]

Not happy. Making all of 403 rwhp and 918 torque on the dyno Saturday. Thought the intercooler started leaking again, but it was still good, I guess the JB Weld held, who would have thought. Playing around Monday morning and BOOM, good thing I was only 1 mile from the house.



Turbo is suppose to be good for 500 rwhp. I should have limited the boost to 40 like Keith told me to, but I didn't think 45 with spikes up to 47 psi would kill it, my bad. My buddy's 2001 goat with the stock HX40 made 548 rwhp on the dyno with a shot of spray and stays together fine.



Not sure what to do now. I leaning toward just getting a HX40 for now and doing twins later. But then I think of a Bell turbo and a big shot of spray would make me happy too. The head gasket needs to be done before the twins or the spray, I want to wait as long as I can and just get the PDR stage 2 head when I do the gasket.



Think there was something wrong with the Diesel Dynamics Jammer turbo from the start, never heard a turbo that loud in my life, thought it was normal, now I'm not so sure. Whatever, to late now.

There has been a couple reports of third gen trucks taking out KSB1's as well. It looks like there's something new going on here and there's still some learning to do.

If it makes ya feel any better I blew up a KSB-1 on my '04 . Atleast you got to dyno your truck. My turbo blew on the way to sho pto dyno my rig. Oh well, **** HAPPENS !!!!!!!!

 

[Rhondasway]

I ran a turbo that sounded bad right from the start, and sure enough, it blew within a couple hundred miles. I'd gotten it rebuilt by PDR, and they stood behind it. Is DD going to back their product?

If not, I'd suggest trying a Bell USB, it's what I'm running now, and have hit over 50lbs once or twice or maybe more... Of course, if you're heading for twins, that HX40 will be usable there, just don't juice it and kill it before it gets a chance!

When you do your head gasket, I'd O-ring the block; I did. I'm replacing my head now and I don't have to pay to have it ringed since the block is already done. Just MHO...

The Jammer is loud and doesn't have a silencer ring. Taking it over 38 psi boost is asking for trouble.

Sorry I misunderstood. I just read in another thread it was the Jammer on your 97 that blew. My mistake.

If DD warrantys it,id consider you lucky, like Joe said under 40psi is the limit. Id stay away for the HX40 unless 99% of your driving is average,if you have a heavy foot a lot of the time,or drag race at all stay away from it. also it needs to stay at 38psi. I ran a large housing b1 well over a yr with no trouble at all,54psi with #2,and 60psi with nitrous,never seemed to hurt it

40's are gonna die if you push it over 40psi too many times--they're just not strong enuff IMO for the HP crowd--chris

I should've just left the Jammer on my 03, it worked perfect on that truck. But then again, if the Jammer was still on the 03 I'd be itching to get the TST. Pretty sure the TST box on top of stage 3 injectors would take out the turbo on that truck too. Sure don't need to hot rod two trucks.



No warranty on the turbo, but keith offered me a deal on a new one, but I wanna try something else. I'm leaning toward the Bell USB, but who sells them? And could they handle like a 100 shot of spray? I'm not too big on the bottle, but I might try it a time or two.

Swayse,

I think you would be pleased with a Bell turbo.



I have been working with Pius on the USB for the 03-04 for a while. He should be sending me the finished version out on Friday. He is also working on the twins for our 01, Pius has some things he wants to try that I have not seen or heard of yet going to give it a shot.

Unless you use them in a twin setup then they seem to work just fine .

I have a Bell USB with 1100 miles on it for sale for $1000 + shipping. I bought it new from Pius about a month and a half ago. It still looks new.

That's a good deal.

I just don't understand buying a turbo to make horsepower and not being able to take it over 40lbs... Even my PDR HX35 made 55lbs uncounted (hundreds? ) times.

 

[Chace TX]

Last Post?

The Bell is good to 55lbs. 40lbs is max for the jammer (I guess) not the Bell.

Propuller. . "Unless you use them in a twin setup then they seem to work just fine"

Kurt

just an FYI

Nowel aka HVAC ran a stock 40 as a top turbo for well over 2 years and saw 90 + lbs boost many many times in fact the fellow who just bought it said the read out button on his SPA gauge said 93 that was on it's last run which was on the dyno which gets lower boost ##'s.

so guess they work ok there also LOL

now I'm not saying run them over 40 as a single cause I know better LOL

 

[csutton7]

thanks Propuller for makin that clarification--I meant using it as a single--many guys push it to 45psi and HVAC had a 40 that lived a long time when used as a single--he had the touch--but for the most part they just can't take the overboosting and barking---chris

Mine doesn't seem to work good..... it does..... period!

[propuller]

I couldnt agree with you more Jim. The Piers modified turbos are absoloutly awesome.

I missed out on Ron's Bell USB turbo, that was a great deal. I gave a buddy of mine Ron's number two hours before I blew mine up. So he had the first crack at it. I guess I'll save my pennies and just bite the bullet and get a new one, I'm all about the Bell USB turbo now.

 

[Forrest Nearing]

my 40 sees over 40psi regularly, but not for extended periods, and generally only in high gear... I've developed a whole new driving style with this truck... my brain has been programed to not lift instantly under any conditions... barking/huffing a turbo is MUCH more damaging than overboosting...



per Holset's website, the HX40 is still on the edge of the map at 45psi at 55lbs/min (roughly 550hp at the flywheel)



but, in a racing application where you're in and out of the throttle, the more boost you're running, the bigger the "ouch" when you get out of the throttle.



thing is, you run into diminishing returns on boost vs. EGT vs. shaft speed when pushing the compressor... and you can make the same power at a lower boost due to better compressor efficiency.
