Hey guys, I recently purchased a Radix with the group purchase. Should be here in two weeks or so. :rocking: I just have some questions about some other things to go along with it. I plan on getting a FLT level 5 4L70E tranny http://finishlinetrans.com/store/product_info.php?cPath=1_22&products_id=31 I will be ordering the tranny after I get the supercharger installed. The stock tranny should be okay for a few weeks if I don't thrash on it too much correct? I am also planning on going with a new stall converter such as the Yank TT 2600. http://www.converter.cc/converters/truck/truck_main.htm It says 2600 stall with a stock 5.3, but I'm sure it will stall much higher with a supercharged 6.0L. I haven't spoke with the guys at yank yet but I'm just curious what do you guys think it will stall at? I don't want a stall too high because I do tow things from time to time with this truck. I would like to keep the stall around 2600 or so. I just want something to get me off the line a little harder, and I like the 2.1 STR also :devil2: I also plan to get a bigger tranny cooler to go along with this too, I haven't looked into them much yet, any suggestions? For the gauges I would like to remove my stock cluster and get one with the tranny temp gauge to take care of that part, and I wanna run a triple gauge piller. I was thinking Boost, IAT, and A/F ratio. Does that sound about right or would you guys suggest I run something different, or more gauges? For the tune im gonna go with Nelson Performance and get a S & D tune since hes only 30 miles down the road from where I live and I have heard ALOT of good things about him and his shop. I also plan on getting a cam in this thing but thats a ways down the road. Do I need to change from the stock spark plugs or can I just use those? I have also read up on the thermostat and it seems I can just keep the stock thermostat and be fine. I know this is alot of questions at once but I have never owned, or installed a supercharger so I just wanna get as much info/ suggestions as I can so I can do this right. Thanks for the help,
Sam

If you just get an escalade cluster it has a tranny temp gauge and it's plug and play. It's already in the harness for it. Stock thermo will be fine. Install should be easy since the kit comes with EVERYTHING. Definitely get it tuned afterwards because the stock radix tune leaves A LOT on the table. Any tranny cooler w/a GVW of 25K should be fine. 2600 stall is going to be perfectly matched to the charger. If the price is different between that tranny the the FLT level 5 65e I would just go for the cheaper one. I havent heard of anyone busting one yet and plenty of people are pushing 500+ hp through them. Sounds like you made a great purchase :head:

I never thought about that. Where can I scoop up one of those clusters pretty cheap? Also is there anyway I can get my mileage put on it, the truck only has around 7K or so. Yeah I heard the stock tune isnt that great but Nelson should be able to take care of the tune part. Any suggestions on a good 2600 stall? Do you think the Yank TT would hold up to the torque from the radix? I haven't called yet on the 4L70 the reason I was gonna get a
4L70 is because I read on a thread on Ptrucks.net that in the 4L70 GM has "introduced an input speed sensor or a turbine speed sensor. To accommodate this sensor GM redesigned the pump, stator, internal wiring harness, input shaft, and the speed sensor itself that plugs into the internal wiring harness." http://www.performancetrucks.net/forums/showthread.php?t=385719 Here is the thread, its a pretty good article. I just didn't know if the 65E would work or not. Thanks for the help man, appreciate it. :shake:

65e would definitely work and will totally handle the power if it's built by FLT thats for sure. Any dealer will be able to fix the mileage and have it put on your new cluster. The yank TT will without a doubt be able to hold the power of the radix. You will have a very stoute setup when your finished. Probably a low 13 second truck :imo

Phew cool, thats good to know. I used to work at the dealer in town mabye they will give me the hookup. I'll send yank and e-mail and see what they say. Yeah thats what I'm hoping for a good stout reliable set-up that can still tow some stuff and haul some ass at the track. It will be really nice when I get a smaller pulley and a cam down the road. :evil: Thats the plan anyway.

Call up Dave or Matt at Rock-On if you're buying an off the shelf trans, I've seen plenty of theirs thrashed and keep on ticking. They have FAR more hydraulic modifications than anyone I've seen.

Yank makes by far the best converter for the money I have a Yank TT2600 and it stalls exactly up to 2600 but with a SC you can forget about it stalling only to 2600 from what I have read up on the subject your looking more into the range of 3000-3200 stall speeds.

Congrats on the blower. You're going to love it! :D

My tranny lasted 2 weeks, behind my whipple at 6 psi. I was beating the shit out of it though. :LOL: I replaced it with a FLT level 5, and its been great ever since. I also had the Yank TT2600. It flashed to 2800 in mine, which was perfect for the cam I was running. It's pretty mild, and it felt almost stock after a while. When I started collecting parts for my current build up, I snagged a 3 disk PI 3200. I'm looking forward to seeing it in action. I think the Yank is exactly what you're looking for. As for the tranny cooler... get the biggest one you can fit in there. It's cheap insurance.

I have 3 gauges in my pillar pod... boost, fuel pressure, and an Aeroforce scan gauge. It is one of the best things that I've gotten for the truck. I would highly recommend this combo. The scan gauge allows you to monitor the IAT, like you were wanting, and about 20 other things, along with the ability to read trouble codes, etc. It's a hell of a product.

I would suggest running a slightly cooler stat and NGK TR6 plugs.

Start saving. Running a blower in a heavy truck is not cheap. I've replaced everything but the transfer case in mine. :LOL:

I hope mine lasts longer than 2 weeks. But I don't drive my truck very often, I usually drive the work goat. I will definately get a big tranny cooler. Where can I get this scan gauge from? Does a 180 Stat sound good? Thanks for all the input/help fellas.

Lemme see what I can find. They're up in Denton.



Also, you need to address your G80... I'd junk it for anything else and a girdle.

Yeah I know, I have been looking around for something used to throw in there for now since I don't wanna spend too much money. Those rock on trannies are pretty nice too.

So far from what you posted and what everyone inputed sounds great except I believe a AF gauge is pointless. It is more of a light show when driving. It is only really good for tuning and I would replace it with one of the scan gauges.

They will tell you if you've gone lean by dropping fuel pressure too...
