Bully Dog's j-hook & HY35

[WTBurke]

I recently obtained this little device manufactured by Bully Dog that allows you to squeak out a few more pounds of boost from the peanut-whistle HY35. The device comes with instructions on how to install and adjust. Well... I first noted the install for the bracket under the two 10mm hex nuts behind the waste gate actuator instructs you to place the drilled hole at the top and the slotted guide at the bottom. This configuration will cause the j-hook and spring to cross over the top of the actuator-rod in a very awkward fashion. I noted the bracket hole alignment to be poor as it would not slip onto the studs once the 10mm hex heads were removed. I fixed this by drilling out the single hole at the top. It then slipped onto the mount studs correctly. I found by turning the bracket upside down (contrary to the instructions) the assembly than paralleled the actuator rod correctly and allowed the j-hook and spring to attache to the waste gate lever in a graceful manor. Now, once this was done, I found the miniature turn-buckle adjustment mechanism was also a problem. The instructions explain that once mounted you adjust this turn-buckle and place preload on the small spring. It states that you are to "stretch" the spring to a total length of 1 and 3/4 inches during this initial adjustment. Well... . you can't do it because the threaded J-hook and the rear spring holder rod bottom out in the hex-turning sleeve. Well... back to the shop, and out with the Dremmel-Tool to cut off about four threads on each end of the small respective rods. Once this was done I had the "through adjustment" to set spring tension and attempt to stretch the spring to the instructed spec's. The spring is only 1" in the relaxed state so this miniature adjustment will only allow about 3/4" of total preload stretch. I'm assuming that's enough as no one should exceed 28 Lbs of boost from the HY35. It is after all just a quick little peanut whistle for bottom end performance.



Unless I'm totally wrong about my experience with this device, I am surprised that the Instructions are so very incorrect and the overall machining of the assembly is certainly poor in every aspect. My mounting position change of the bracket assembly will allow for easy adjustment, unlike the Instuctions suggested method that will make fine-tuning of the preload a real PIA. The small incremental touch-up adjustment should allow for spot-on settings of 25 to 28 pounds of boost but,... wow... I didn't know I was going to have to do all of this just to get this little device to operate.



It is a clean little assembly and beats the "hay-seed" method of a turn-buckle with spring but... damn!



Is there anyone else out there who has had any experience with this Bully Dog J-hook device?:{

I have it, it bolted right up for me. I'm not sure why you would have problems with it. Here is a pick of how it fits on my HY:

BDR,

Thanks... nice photo, and I see it crosses over the actuator rod. Were you able to achieve the boost required with the spring stretched to 1 and 3/4" ?



William

 

[BDR]

Boost wise I'm around 25-28 psi with 1 3/4". Works great with how its set now. I haven't had any problems.

 

[WTBurke]

BDR Thank You

I modified mine to parallel the acctuator rod by mounting the attachment plate upside down. This allows easy adjustment with a couple of 7/16" open end wrenches. I've now learned from you that just placing it as per instructions doesn't really require adjustment and the boost levels you have reported is very fine.



My closest observation is 27 PSI and I'm going to call it good at this point.



I created a lot of stress for myself in reworking this little device thinking "adjustment" will be required and the placement of the device as it crosses over the acctuator rod makes adjusting the sleeve very difficult.



Oh well... live and learn.



Thanks again,

William

I bought mine at Lowes for about $2. 79 before changing Turbo's

Huh I remember back in 01 simply drilling out a . 22 caliber shell with a #26 bit if memory serves me right. The Hy has a "Hardline" wastegate actuator and rather than doing the spring thing the shell slides right in place where the hardline enters the compressor housing. You can make different sizes to make the gate delay open, bleed open or just keep it closed. I think the "Safe" zone for the hy is about 28. I got it up to 46 lbs once but that was just to do something to giggle at with back then were what were considered "BIG" DD III injectors. The poor thing was so far outside the map. It turned the turbo gold , the piping gold and fried the paint off the IC on the passenger side But hey that was 6 years ago. :-laf

Tool Man Tim...

Thanks and good response as I do recall that little trick but, I guess old age is doing me in these days.



You don't recall what size hole to drill in the spent shell?



Also, I looked at the hard tube and how would I remove that little elbow... it looks as it's attached with extreme authority?



BTW, you directed me years ago to correct my front axle for "centering" and that lead me to correct that great error... boy my truck sure drives sweet now.



Thanks

William

 

[WTBurke]

Sorry Tim,

I just read your response again and the "hole" size is much less than the hole in my head



William

 

[ToolManTimTaylor]

Hey Will,



It is a small hole and Like I had pointed out I BELIEVE it was a #26 bit (Larger of the "Furnace" size bits. )



Anyone know the # system on bits?

 

[WTBurke]

Thanks Tim,

I have #26 bits and a few smaller or bigger but, how does that hard-tube come off the compressor housing. I looked at it again yesterday and that little bugger is really on there tight.

[ToolManTimTaylor]

Should be the wo 8 or 10mm Nuts that hold the actuator in place. It comes straight out attached to the actuator so in a sense you simply unbolt, and "Lift". Is that #26 teeeny tiny small? The hole should be a in the range of a thumbtack pin.

 

[WTBurke]

Tim,

Thanks... I was looking at the hard-tube on the front of the turbo housing that's pressed into place. I'm going to go remove the actuator and look at the correct location. For some reason I'm just being lame about this observation... . I don't know how I missed this
