This is my Procharged SRT 6.1
I built it before there was such a thing as a hellcat. It's been fun, reliable, and easy. It makes great power and for sale. I'm selling because I'm looking at a new chassi for my big Hemi. I pick the kids up from school in it on nice days is about all I drive it anymore. It's 1/2 price of a cat and only has 29,000 miles. So if your looking for a modern muscle car for under 30 grand PM me.

I'm working on a procharged 340 project myself. It is getting close to completion but the holidays set my machinist back some time wise.

My build is using a D1SC with cheapo front mount intercooler. I have been doing it on a budget (whatever that means, for a forced induction build) so I welded up my own piping and found what may or may not have been an incomplete SDCE bracket that I am heavily modifying to make my own pulley setup with.

the blower is feeding the following
69 340 block, hughes main girdle/studs, factory forged crank, Eagle H beam rods, forged pistons, ported W2 econo heads, E85 fed via aeromotive A1000 fuel system and FItech 1200 fuel injection, solid roller cam

What really sucks about this build is not being able to find brackets/pulleys for cheap. I sourced a billet SDCE one piece crank pulley/blower pulley for 300 something and then the work I have to do to make the bracket work.


Honestly, I think TURBO would have been a MUCH better and probably easier way to go. I already had the procharger though. I considered a single turbo, and I know I am quirky for this but I can't get over a muscle car having a tight overlap turbo cam and all the exhaust coming out one pipe. It's just nowhere near as cool as a big, choppy cam thumping out unobstructed dual exhaust.

Whether the sound is going to be worth the power loss of the blower, added stress on the crank/mains or potential belt slip issues- I don't know.

I am hoping to make around 700fwhp with this setup and pray that it stays together.

One of the biggest issues I see with building up MOPARS for forced induction is that many of the stock blocks can't handle the power that good head flow and boost can make, and when you start getting into aftermarket Mopar blocks the prices are so crazy that who has money left for forced induction as well? If you're a late model GM guy, you can go out and find a $500 5.3 truck motor, spend a few grand building it and make 1000hp with a cheap turbo setup. You could probably do the whole build for the cost of a good Mopar block and machine work.

At least this seems like the case with the small blocks. I know SCDE and a few other guys were pushing factory big block engine blocks way harder (well over 1000hp).
For what I ended up sinking into this small block I think I really made a mistake in not trying to do a big block instead.

Bunch of cheap bastards on here, that's why...

I spent money but am still slow.... the get what you pay for mopar surcharge

"I am hoping to make around 700fwhp with this setup and pray that it stays together. "

I believe your hopes should answered without much ado, but your prayers might fall on deaf ears.

Mr. Parts,
There are pros and cons to each. The Procharger is self contained in the lubrication department. The Vortech uses oil pressure from the engine, and drains it back to the pan. When you toast a blower bearing, the shrapnel ends up in the engines oil pan. That can be an issue.

You are correct that most vortechs need pressurized oiling but not all. The v3 is self contained. Only good for around 800hp though. I'm personally a vortech supporter, can usually find them cheaper, it's for a Mopar so, you gotta make a bracket unless you have a gen3. They also seem to take a beating better, honestly seems like you can cog them when vortech says not to, spin them harder than recommended and still keep going. The NMRA is a fun place to explore vortechs abilities. Definitely pros and cons tho, same as turbos and nitrous really. It's all work and money, personally feel all power adders cost the same once you hit the track

Thanks for the info. I've been thinking about a procharged Aluminum 572 for my next street rod & this gives me something to look into.

I really hope not! In the past few weeks I have spoken to a few boosted stock small block mopar guys who are making more HP than I plan to and they are tall telling me to go for it. My machinist didn't think there would be any problem with it supporting that much power and he knows a decent amount about pushing stock blocks (he currently holds the NHRA record for SS/GTAA). They don't seem to lurk here, but there are big power turbo/procharged small block mopar guys out there. It sounds like the biggest issue is with getting the tune down right. Most of the guys who I have heard cracked these blocks were either spinning high RPM's with a N/A or nitrous builds which I would think would put far more stress on a block than a lower RPM blower/turbo build, or had an old school roots blower fed by carbs. I know roots/carb setups have always been notoriously difficult to tune, and the few people I've spoken to who have cracked blocks really couldn't confirm if detonation was the culprit or not.


I'm hoping that with the fuel injection, E85 and wideband I'll have a better shot at keeping out of detonation, and I shouldn't have to spin the setup too high to make power. Take a look at Dizuster here. He is making well over 700fwhp on a stock magnum block. Magnum blocks could be stronger than early 340 blocks though, I'm really not sure.

Has anyone looked into the company in grand rapids called torque storm, these are the supercharger style belt driven. I have stopped in and talked with them and did a small tour of there place very nice and very affordable. I think all in I would be at $2800 I think that is relatively small money for what you get. they come set at 7psi with pulley swaps available up to 12psi I think. or cut your own pulley and void the warranty, no difference either way. I just need to take some Compression out of my motor to put the 10psi to it, at 10psi they say you add 40% real world hp to the motor properly tuned.

If I was going to do a forced induction setup, it would definitely be a supercharger. Turbos require too much plumbing and take up too much space. Not arguing b/c turbos are the best for making power, it's just personal preference. Not to mention turbo cars are usually a little too quiet and docile sounding for me.

The main thing that keeps me from going that route, other than the cost, is packaging. I don't really want to hack the frontend of my car off, fit all that stuff, and then try to lay the car's skin back over it. Nitrous is much easier to fit on the car, lol. Then again, I'm not trying to outrun everyone and set records either.

I guess one of the things that attracted me to going this route is that you don't see a lot of them out there. Plus I'm looking for a car I can drive on the nice days. And still go run at the local strip when my job allows. My true goal would be a high nine second car. But I know that will take time dealing with chassis setup. I'll hopefully get started this year.

Chip you need some rear mount turbos. 😆

Some may be that most older guys like me in their 60's and up like what we grew up with which was no super or turbocharged cars as you just never saw them much at all back in the 60's and 70's muscle cars era. The technology was not so good and they did not work as good back then. I like mine as they were back then which was naturally aspirated. And then when the 80's came around Mopar did not have any rear drive muscle cars and kids were getting into the imports and the Mustang and Camaro was still around. So I think many younger just did not get into Mopar as much since for many years they were not much into any performance cars. Course many older people like me dont want a power adder since we did not see them much when we grew up and we did not want anything to do with Imports because in the 60's most Americans said if its made in Japan its junk ! And I think alot of that was still feelings from WWII in the country. We were more patriotic to America also back then so Imports were something we stayed far away from back in the days or many of us did. Now Mopar have finally came out with a strong supercharged V/8 car and maybe more will start using super and turbochargers on Mopars. Just a theory but I may be off base some. Myself I just love the N/A V/8 eng that I grew up with and I like my muscle car simple and easy to work on now that I am older so I know I will never use a power adder but I dont need to as I am not worried about having to go that fast. In todays world if you are very serious about wanting to be the fastest around you have to run a power adder of some type. Ron

I have played with a couple 440 with carburetor setups, both using Procharger D1-SC head units.

First issue is cost for a lot of people. A centrifugal supercharger kit with mopar specific brackets (pre gen III hemi) tend to be pricy. I made my own brackets and modified the other pieces needed from a BB chevy kit.

Second issue is tuning. I am not a fan of blow thru carburetor setups. You tend to have to run too fat with little initial timing during the 98% of the time you are not under boost, or run lean when you are under boost. Running lean under boost is a short term problem, because you will blow head gaskets, burn valves, or torch pistons/blocks in short order. I would view a blow thru carb setup for a track only car as more viable than a street/strip car, because you can treat the carburetor like it is mechanical injection. Tune it for wide open throttle performance, and not worry about how it runs when not under boost.
If you run fuel injection, you need to have a system you can tune, or have someone with the ability to provide the tune for your car. If you run a centrifugal or a turbo, fuel injection is the only way to go in my opinion.
The fox body mustang guys are the ones who made the centrifugal superchargers commonplace again. They had fuel injection, and a large enough following that the aftermarket could profit from by supporting them with parts and technology. Mopar guys are just now getting late model fuel injected cars worth throwing a blower on.

Most Mopar guys are content running traditional set ups. They are easy to put together because the combinations have been used forever, produce enough power for many street strip guys, and are familiar. The trouble begins when you get beat by a guy running a 2.0 liter econobox, or get to ride in or watch someone with a V8 under boost.

There are other issues that come up, but if you have the coin, can run fuel injection, tune it, and mount the head unit up, you are well on your way.

And, don't plan on getting any technical advice from the manufactures as to how to get your car to run with their products. They don't have the answers, you will have to figure that out on your own.

What room problem? What lag problem? What temp problem? What oil contamination problem? What belt slippage problem? What custom build problem? 700HP from a small block? - not a problem.

Not sure who's carb you were using, but that is not true across the board. The fuel curve under boost is easily controlled with the latest boost reference power valves. Acts 100% like a normal carb, until it sees boost and then goes as fat as you want it to. Piece of cake... The ONLY time I've ever had carb issues is when I'm getting outside the power window of what it was set up for. When I tell the guy it's only going to make 700hp, and I'm trying to push it to 900hp... yeah it needs a bunch of jet!

The timing thing is no big deal either. Lots of boost reference options out there that will control timing. Lets you run full timing at no/low boost, and pulls out as needed. I actually have full timing (35deg) in my motor up until 5psi to get the turbo lit, and then a yank a bunch out from there. No different then setting up an EFI timing map.

I would say there aren't lot of procharged mopars out there, just for the same reasons there aren't a lot of big power mopars out there in general. People are scared of the stock blocks, and the race blocks are scarce and/or big money. Average guys don't want to spend that kind of money or take the risk of blowing up stuff.

Nothing wrong with the prochargers at all... LOTS of non mopars successfully using them across all platforms/ all years of cars.
