My wife refuses to let me get her a Escalade. I have a stout LQ9 in great shape with less than 30k miles. I have had the valves worked, heads decked, and will stud and ARP the whole thing. I'm kicking around perhaps the Lingenfelter GT2-3 or similar mild blower cam for the short block and trying to find a 112 blower to top it off amd drop it in. I'm not looking for a race truck I just need to swap the 5.7 and have everything but the blower and cam. What chassis power should I try and get to make the swap easiest? Would pulleying down to 10-12 be an issue after the swap was done and the exhaust is dialed in? What kind of power should a mildly worked 317 headed LQ9 with a blower cam at 10-12 psi make? Any pointers or suggestions I'm completely all ears, thanks

 

A mildly freshened up 6.0L with the GT2-3 and the little MP112 will run good. It’s the same basic combination I’m running, except in that mine has 6-tenths lower compression being an LQ4. I do believe you are going to come up a little short on your target boost pressure of 10-12psi with the Radix though, it’s just too small of a unit to put out that much on an engine much larger than the 5.3L. I’m getting about 8.5lbs out of mine with a 2.800” pulley and while you can get a slightly smaller upper pulley and even a larger overdrive damper is available, I feel you would be reaching a point of greatly increased IAT’s without much if any gain in performance. Also, some people have run into belt slip issues trying to go much smaller on the upper pulley. I feel like you would have a very enjoyable Tahoe with the plan you have just as it is, albeit with a little less boost than you were looking for at a reasonable expense, but if you really want to push it a little further you may end up wanting to at least search for a TVS1900 to have a chance of getting it there. Even with a 2.900” or 2.800” pulley, you would really want to install a methanol kit to be able to run a decent amount of timing in her, especially with the higher compression LQ9.

 

I want low maintenance, no meth, 93, optimized DD setup for a 4WD fun/tow/party wagon. I was thinking the 112 because they're so cheap now. What chassis is best to get the blower from to swap in my 96

 

What you goin to do about transmission?
and what you mean about chasis power? the main power for the PCM/Fuse block to turn it on?

 

i have a transmission for sale of 04 SS if u interested
