So I'm working on putting my truck together here's the specs
-lq4 based stroker and supercharged mp112
-4l80e
-hd transfer case
-custom drive shaft hd joints
-14 bolt 4:11 with e locker
Truck is a 2004 yukon denali converted to selectable 4 wheel drive, it also is lifted 7" and on 35" tires.
My questions are first converter for the 4l80 what stall would I want for a lifted truck? Also I do tow.
What cam would assist with alot of bottom end and compliment the magnacharger? I would like a little aggressive idle too.
Would it be beneficial to upgrade to a larger magnacharger?
Anything thing else you guys want to suggest or point out is appreciated. Thank you

 

The first thing id do is go with a 4.88 gear (im running 4.56s with 33s) dont fear the gear, than id look into which convertor can handle the extra power from the supercharger along with the added weight when towing. You will defiantly need a multi-disc IMO, 4l80e multi-disc can be very expensive though.

 

are you looking to do a 408 stroker? The MP112 is goin to be out of breath on the 408 im sure.

 

Your right should I just stick with my forged lq4? What can this mp112 crank out comfortably boost wise?

 

I wouldn't go past 370 cubes with the MP112. Keep the cam small-ish, the Trucker cam worked great for me & many others. 216/224 .551/.551 115 LSA. A 2800 or 3000 stall would work great with that setup.

 

im getting a stall for my truck soon and it will be super charged and its a 2500 with the 4l80e and I found that yank will make me a stall that allows me to keep my stock ratings for towing and I think it was a 2800 rpm stall so I hope that would help

 

If you tow keep the stall speed under 3k. For gears 4.56 or 4.88 would be best to match the 35s and weight of your truck. A forged lq4 will be similar in cost to any other motor. I would suggest a bigger super charger such as a tvs 2300 and a 370" motor. That way you have plenty to grow with just pulley down and crank up the boost until your happy with the power. A custom speced cam would be best and only costs what $20 more. Though a 216/224 is a good off the shelf option.

 

408 and the 112 isn't going to make the greatest power. Will be out of steam fast.

 

Well I have the forged 6.0 with ported 317 heads already and mp112 I guess my thoughts was to want to go bigger but it's obvious not a realistic idea. Thanks for the info on the stall. And I didn't want to change the gears but I guess I will.... Can't Imagine this thing when it's complete

 

What size pulleys do you have for it?
