Charge Air Cooler / Intercooler

……… so the B series ...3.9 …. uses an engine coolant intercooler...,mounted on top of cyl. head ...in place of the intake plate .

 

[olympicorange]

………... went for alittle ride to today ..to the PEAK.... stopped in to see what our pals had new & exciting on the lot … theyre busy...and a new model...

 

[olympicorange]

........ took a few hrs. off last nite to watch the racing at the local track... and the previous owner of the tucker project... great fun Dave …

 

[olympicorange]

………... happy labor day to all... got a little side tracked this afternoon, … helping my painter buddy billy … ( whom painted the old Littleton off-road riders tucker, in a previous post, with mr. loggah ) . on a project that he needs to finish...before we can start on my ol tucker....

 

[olympicorange]

,...….….. oh... these two 1971 's are for sale … 399 skidoo …. 292 arctic cat.... if anyone wants to add to their collection… thx ...

Must be doing the drive cogs while it’s apart? I found cutting the rivers down through the worn nylon sprocket with a cutoff wheel on angle grinder then gingerly working the side plates of works best. Stainless nylons and bolts for the install.

 

[olympicorange]

……….. finally arrived …. GM brackets...thx BFT... these are the bomb... let the welding begin.... decided to go with the same mounts as the engine....same...same.... simple...simple.....

I'm glad that idea is working for you, and you were able to get the castings without too much trouble!

We just used some sections of rubber belting, roughly 3/8" thick, between the GM castings and the Tucker frame mounts. We cut the frame mounts down so they could be welded to the inside (rather than the top) of the Tucker frame. This mounting location allowed for excellent alignment off the transmission output and transfer case input. But, as you know, your situation my be different as the engine placement may dictate something else entirely.

(Really enjoying this thread!!!)

…….… yes, the shape of mounting brackets adds a lot of support. it took some serious ''leg-work'' , web surfing, emails, text, phone calls, etc... to locate a set. all the way from Stockton. the right side mount almost sets perfect to the frame. the left side will require alittle more Fab. work, due to the fact that the Allison doesn't align to the ''B'' perfectly straight /inline. it is slightly ''cantered'' offset in the bolt pattern. fairly common with a lot of diesel's . it was less of a drastic offset ..''CCW''...as opposed to the ''CW'' offset. so that will be the next task at hand.... thx again BFT....

 

[olympicorange]

……….. wife's BDAY, off to her old stomping grounds ...Alway's entertaining... nothing like the ''Big Apple''..... ( so progress ''on hold'')...

 

[olympicorange]

……. progress on tranny mounts ...fabrication....

 

[olympicorange]

……..… and the tranny ''jig'' comes off....

 

[Northcoast]

Well done!

 

[olympicorange]

……. put the rubber to it...…

 

[PJL]

Looks like it's ready to fire off.

 

[olympicorange]

Looks like it's ready to fire off.[/QUOTE

….. pretty close … yes... fluids, belt, batteries, exhaust, alittle wiring, … time to make some noise... and smoke....

 

[olympicorange]

…….... score....went ''pickn'' at one of my favorite supply yards...

 

[olympicorange]

……..…. a better look at the ''spoils'' from the treasure hunt...

 

[olympicorange]

,..... hey all, .. been crazy busy this last month,... been out searching and gathering.... will disclose more in future post.... mt. Katadin…. one of many stops....

 

[olympicorange]

… a few more connections,... electric fan,....

 

[olympicorange]

………… primed & cranked... oil pressure 60 psi... fuel inlet supply pressure 30 psi... water temp 190 ' ,... 13.0v …..

 

[olympicorange]

..………. so, … as everyone knows...the best layed plans can need a tweak , or side step,... due to things ; such as … timeframes, changes in priorities, design improvements , etc.... or better yet ;.... a paying project. so I am going to reschedule the body mods , to next year ,... and reinstall the cab,.. to take on a ''re=power /trans.'' project. to a very special unit … which mr. Loggah has posted previously ….

 

[Blackfoot Tucker]

I understand the change in plans/priorities, but I've really enjoyed this thread.

I'm sure I speak for many when I say I hope you start another thread about the new project. (That should keep your fans satiated until you can resume this one....)

 

[olympicorange]

…… hello BFT, thanks !! … again, … I really appreciate the support , right back 2U,.. I know you juggle also,... so i'm not going to ''stop'' ,.. I like to say ...''side step... ''re=prioritize'' ,... I 'll suffer one more winter, in the little cab, so as not to rush the body ''enlargement''..... all good...

 

[olympicorange]

……… ooops ,.. yes … new thread is,..... ''Nellie Bell''.... hope y'all enjoy,...thx for following,....

 

[olympicorange]

.... And again... Kool aide color...

On the four cyl Cummins install, have you considered moving the radiator forward to the end of the frame inorder to use a mechanical fan? In the past I have not had sufficient air flow with electric fans to cool. Perhaps today's units do the job.

We had cooling issues with Thundercat that were very frustrating (and costly) to solve. Griffin Thermal Products recommended one of their "universal combos" (radiator, shroud and two electric fans) for our application, and claimed it would cool "up to 550 HP". Except it didn't. We tried everything they suggested; and nothing worked. Taking no responsibility for their recommended product (that quite simply failed to do the exact job for which it was recommended), I was done with Griffin.

I turned to Ron Davis Racing in Phoenix, and they were helpful. The technical representative said mechanical fans move more air. Period. But, we simply didn't have the necessary real estate for a mechanical fan. The next option suggested was using a hydraulically powered fan, which are used on several vehicles. That became the second option if the larger Ron Davis radiator with bigger fans didn't do the job. Fortunately though, the new Ron Davis radiator and fans worked. We also had the ECM re-programmed to change the fan on and off temperatures. The first fan turns on at 184º and off at 176º. The second fan comes on at 204º and off at 196º. This combination seems to work well. (I'll also say the quality of the tig welding on the Ron Davis radiator is incredible. I literally dream about having skill like that....)

I also have considered using a hydraulic driven fan. It makes more sense than an electric fan with enough HP to move that much air. You already have the hyd. pump which is more efficient than beefing up an alternator to supply the electric fan. I like the "progressive linkage" of your fan set up, reminds me of the dual AFB's on my 409.

Good news that you found the Davis option, it is well needed. Thanks for sharing what works and what doesn't.
