Hey all,
Decided it was time to bring some added bang to the party on this thing.
One time I thought maybe a LS swap would be a route i took, But those ruin the whole character of muscle cars. Imo. A well built sbc or bbc can do anything a LS can do. So After weighing my options I decided I'd give my little 355 some help breathing.
Been putting together a list for the brown Santa, and one day he showed up with a made in the USA, billet aluminum torqstorm.
I know this is a truck site and a centrifugal might not be the first choice and all, but anyone thinking about a centrifugal for their rig, these things are beef.
Only good for about 700hp they say, but lots of guys pushing them beyond that.
Anyway I put together a little intake to light it off with MFPI and a coil near plug setup.
So the plan is to toss on that stuff, with a terminator x and some corn juice and see what it makes.
Currently I'm in mock up stage. But will start a teardown in the week after next when I get back from a little trip out of the country with the wife.
Mockup went pretty well. The only real issue is the upper radiator hose is to high for the supercharger discharge hose.
I switched to a lower outlet thermostat hosing fixed that and a different hose setup. (Fix not shown here)
Going to run a air to water intercooler.
Found a reasonable place to snuggle the A2W unit down in the passager front corner. Not at all where I envisioned it going but it worked out ok'ish with some summit silicone connections.
Was thinking about welding up some pipe for all that, but I'm only going to push 8psi right now, so why bother. Nothing ground breaking in terms of boost.
If I end up with a dart block sbc 4xx something I will weld up some intake tubes and crank up the psi to 12/14. End goal would be 750ish maybe 800, with a 475/500ish hp short block those power levels are EASILY achieved. Like I said, who needs a LS.
Anyway, once i strip down the car a bit. All the old stuff in the engine bay will be removed and I'll start with long block.
Going to rewire the entire car with a american autowire harness, ordered up some green line gauges. They only have a basic tach, speedo, oil, water, fuel, volt, guages so I called up speedhut and designed up a air intake temp, oil temp, and boost gauge. I'll still have the holley screen. But nothing matches the style of a sewart warner greenline. Pure class.
I grabbed a derale hypercooler to plumb into the oil system to help pull more heat out of that all iron sbc, (although i serious doubt its an issue with e85) And a ZL1 intercooler pump to move the water in the Air to water system. The A2W system has its own radiator I'm fab'ing in front of the core support.
This system will have a small reservoir I picked up from canton racing and a precooler with a switched spal fan. The reservoir acts like a heat sink and the switched fan is to move air at a higher rate when your moving slower. A couple of the heat tricks I picked up with cad v series ownership.
Of course with e85 you need a bit more fuel so it's out with the Ole -6 feed line and in with new -10 unit and the appropriate reg/filter.
I have a small handful of other little things to finish, that I never got off my ass and totally finished before.
And a few other things I just don't love from before.
I have a set of corsa mufflers on order. I had those on my STS-V and loved them, they kinda evolved into a favorite of the coyote crowd as of late but they sound good and have been wanting to try them on a non overhead cam engine for a while.
Anyway. Happy supercharged summer boys!

I am good with any way to boost.
And welcome back by the way

I agree.
The goal was to build a boost package that could be easily swapped over to a boost ready long block.
And it all started when I found that mfpi manifold on a holley clearance sale for 152 dollars.
Probably that most expensive 152 dollars I've ever spent..
Awesome update, I like the plate on your car. Good to see you post up again.

Meh, my wife looked at it and said great head?
obviously not quite what I was going for...
I didn't even think of that and I'm normally right on that level.
Sounds like a potent combo! Looking forward to seeing it come together.

We will see,
I'm only shooting for 500 (at best) crank right now.
It if only makes 400 crank I'm good with that to.
If you run the calcs with psi vs NA hp,
It it could be 425ish or 500hp
I am really not sure how much hp it makes now. (Unknown engine specs)
And I sized a pulley from torqstorm to make 8psi.
But since boost is a measurement of restriction, it might be 6, 7, or 8psi.
Also since I'm not sure of the HP level, i am just going off of 300hp.
300hp x 6psi = 422.
300hp x 8psi = 463
325hp x 6psi = 457
325hp x 8psi = 501
Since I really can't control my boost restrictions. Nor my cam overlap. My boost might be higher or lower.
I don't anticipate it being higher then 9 or lower then 5.
I do think it's around the 300, 325 hp mark. So I based these very rough estimates on those factors.
All that said, my main goal here was get an induction package up and running first. Then if I did a engine build that would be set up and ready.
As you can see when I had speedhut copy the classic SW "motor minder" gauge, only for vacuum, boost. I set the gauge up for the future. Full party mode only being 8psi and above.
