Nitrous or Supercharger

[motorheadmike]

A Procharger is a fabulous race piece, but I'm yet to see one that could be considered street friendly. They are definitely a more of a user friendly install though than a turbo install.

Something to consider if you want to spend 98% of your time on the street or actually put 5-10K miles a year on your ride. My opinion of course

Really? I have a D1SC on my TBSS and that is a four season daily. Fires right up in -40*C or +40*C.

You should post a few pics. I'd like to see how its set up.

Hmm... street blower only made 200hp less than the race blower.

And you can drive a pro charger in the rain without dying.

Anything can be done - where there’s a will there’s always a way. Just cubic $’s more than a nitrous kit imo (‘mo’ - my opinion - don’t shoot me for it lol.)

The race kit doubled the NA hp (750 NA). The race blower made around 30% more than F1A. So if they had started with a cam’d and header’d 5.3 at 400hp NA, then it would’ve made approx 700hp with the F1A. Equating to approx 600-625 whp in my example. That’s nothing to scoff at, but will cost more than double of a turbo build making the same and more than 6 times the cost of nitrous setup for the same hp level.
To each his own, and I mean that without any sarcasm. Procharger’s are FABULOUS, just not the best bang for the buck if ‘bang for your buck’ is a concern. It’s not a concern to many.

As someone who has built every(?) kind of SBE LS combo there is turbo, supercharged, H/C/I+spray I wholeheartedly agree the biggest return is in a turbo. However it has the most complexity and takes the longest amount of time to produce - especially if you are unskilled and learning. Also, there are some platforms that don't take turbos with particular efficiency due to packaging constraints.

H/C/I builds are a waste of money, and nitrous is only fun in the moment.

The Procharger gets you a 90% solution in a weekend. Time is money to some.

I am still looking for another centrifugal blower for the wagon... but, I'd take a PD blower too.

Kenne Belle makes 4.7 and 4.9 PD/Roots style blowers. That's like putting an entire Frod-mod on top of your LS!

I have a 2.9L 8 rib Kenne Bell for a cathedral port LS, specifically for a Corvette in my garage. The one thing preventing me from installing is my concern over heat. Dude I got it from claimed 600whp on a FRC C5, so a stock LS1. That was probably it for one pull, then significantly less on the next as he was making 15# and the thing has a patheticically small, restrictive brick to cool the charge. If my car had a cam in it (on the shelf) and made around 420whp before the blower I should be able to make 600whp with less pulley and ideally less heat. I think 600 is a good stopping point for a stock bottom end GenIII. But OP has a 408, how built is that and why was 600whp your target if I may?
