Im looking for input on which kit to buy. I've been looking at torqstorm supercharger kits but recently I found this kit: https://www.summitracing.com/parts/vor-4gx218-150l

I'm not looking to run a lot of boost and really my goal is to make 600hp at the wheels. I think I can make with it with either kit. Here are my mods already done

2005 Escalade lq9
Stage 6 4l65e 3k stall
231/234 tsp V4 cam .629/.615 111lsa
p&p 317 heads
Trailblazer SS manifold
Gold plate 90mm tb
Speed engineering 1 7/8 headers
Speed engineering x pipe
Stainless works 3" chambered mufflers
4.11 gears (soon to be 4.56)

Any pros or cons with either kit?

 

Get something with an intercooler.

 

Even with boost in the 6-8 psi range?

 

Yes, non intercooled with boost is a waste of time.

 

Ok I'll add an intercooler to the supercharger kit. Info much appreciated.

 

if you're just looking for a horsepower number, a centrifugal kit will get you there the quickest & easiest. if you're looking for something that'll provide extra moving force you'll feel as you daily drive that 3ton beast, a PD blower like a Whipple, Magnuson, etc. is the better choice, since centrifugals progressively ramp up to full power as you climb in RPMs.

a good turbo setup gives you the best of both worlds: doesn't taper off in high RPM like PDs typically do (without extra work), and the power comes on once it spools up instead of having to wait on high RPM to get full boost like a centri. it's also usually more complicated & expensive.

i could be wrong, but expect to need a bigger set of injectors & at least a BaP or new fuel pump altogether if you're looking for 600 wheel.
definitely do your homework before diving off the deep end of forced induction - it's more than just a good idea fairy.

 

Centrifugal will be nicer to the trans too. Makes an NA power band, just more of it

PD will eat that thing in short order. Plus the stall you have isnt PD friendly, it's already stalled for a centri

 

haha, good point & my bad. it's second nature for me to gloss right over auto trans specs when i'm reading pages

 

Thanks for the feedback. I'm on a budget and although the PD blowers are nice they come with a hefty price tag same as the turbo setup. I'm looking for something easy and it sounds like the centrifugal supercharger is my best bet.

Also I betting the 4.56 gear will get this pig off the line faster with out having to buy the expensive of blower.

 

What about my stock rear end and drive shaft? Will they grenade once I install the blower?
