Forced Induction on a Daily Driver

[driftsucky]

So, like the title says, Forced Induction Plus Daily Driver. I'm thinking about doing some sort of Forced Induction application on the 5.7. PPP was admitedly my first choice, but I've yet to see anyone who actually HAS it. While I still have them at the top of my list, I'm not to sure about that turbo location because we get a lot of snow up here (the undersides of our cars go through HECK). I'm thinking Vortech may be an option because I'm familiar with them (although not with the HEMI). I don't really know what else is out there, but that's what I'm debating on. Anyone have any suggestions. Help is MUCH appreciated.

subscribing - as I am think of FI for my DD also.

from what ive heard, supercharging is more streetable for a daily than a turbo.

id look into the vortech kit. nothing but good results from it across the board from what ive read.giving ~415 rwhp on a stock 5.7 block consitently.

if youre interested in turbos( the mechanics at my speed shop tell me they liked s/c until they put a turbo in their car... every single one of them) then id look into the STS kit. i dont know if its in full swing production yet, but its looked to be very promising,

there arent many turbo setups that are in full production to my knowledge, ive seen a few one off custom jobs with it mounted in/near the engine bay, but the production models like the PPP/STS have all been rear mounted. which aside from the snow you mentioned(im in houston tx :) ) is if some one takes a peak... they can see it and i figure with a hacksaw or something could be off with your turbo.... maybe im paranoid but hell.... its a part that you can hold in your hands that is worth a grand easily.

id really like to see more turbo setups personally, but for what is on the market now, the vortech is where its at IMO.

[zoomzoom1]

I'd like to know how Vortech and Procharger stack up next to each other, been thinking the same lines also??

[landshark]

mine's a daily driver. just picked up yesterday and no problems so far. I started out with a full tank and waiting to see what happens to my mpg. So looks the same as long as I'm not hammering it down.

I have a DD Pro-Charger here and a Vortech they are both very fuel efficient and very streetable. I've installed about 8 Pro-Chargers at this point and 3 Vortech's And I like both systems they are both excellent performers.

any notable differences as far as delivery of power/feel etc?

[PPP-Sales]

I like how the Procharger comes with a large Air to Air intercooler. We have installed them with excellent results.

I'm more familiar with Turbo applications just because of the vehicles I've had. As for the drivability versus a SC, I can't see any real difference. Turbos have the issue of lag (which I can't forsee being an issue w/ a V8) and boost comes in at certain RPMs. SC's are always on because they're belt driven. So, turbos tend to be more "kick in the pants jolt" because of that, but again, it changes when you're dealing with a V8...a rightly powerful one at that.
I've never known gas mileage to change much if at all with FI assuming you don't drive like a jack@$$. I guess my question is more geared towards dependability of kit and motor on moderate boost. I've only had ONE car that I've boosted to high heaven and it was a pain to keep up. If I was still single or just had disposable income and time, I'm sure I could spend the time to constantly test and tune a car to keep it running right. Every other turbo car I've had has been pretty mild for the most part (adjusting for track duties of course, but DD boost was pretty mild) I just don't have the time for that type of hassle anymore. At least not on a car I drive everyday (still tinker with track cars off and on). I don't really forsee myself boosting past 9psi regardless of what I get. Typically, 10-12+psi is where you have to start changing everything.
As long as I can put a blow-off valve on it, I'm not particular to either system. I REALLY miss that PSSSSSSSFFFFTTTTTRRGGGGHHHH sound. MAN, I LOVE THAT!!!!
Price range I'm looking at is 7-9k. Engine mounted is BIG for me though. I don't want anything hanging out anywhere. I'm all about cleanliness. If I'm not on it, I don't want anyone to know it's there.

[BAD MAN 485]

I would like to have a turbo just because they are more efficient and who are we kidding a blow off valve is freaking awesome. I think the super charger kits are cheaper and easier to install as well as being safer due to the water thing. I dont know what ever is cheapest easiest and produce the most power while still being safe is what I would go with. They both produce around the same numbers.

[DaytonaCris]

does anyone have any real numbers on either FI for the 5.7?

[BAD MAN 485]

does anyone have any real numbers on either FI for the 5.7?

there have been a bunch of guys here with vortec's i believe the numbers on a stock car with moderate to no mods were 100hp. I am not positive I know land shark has one but has heads and cam and other mods and he's over 500rwhp. I believe there is a purple and lime green car with vortec's on there cars. I know srt8u has a blower on there srt.

[landshark]

real numbers with very few mod's I have seen are right at 400 wrhp and 400tq. Stock 5.7 motor is about 270-280 wrhp and can gain with a good tune 125 wrhp with no problem.

yup sounds about right to me I am thinking about doing a zex kit on my car get that 100hp for 1/10th of the cost but its not always there which blows.

those are good numbers, I was wondering about an SRT8, stock, what it would do.....thinking of doing mine....

The guys over at BMC have there pretty much stock SRT with a vortec I know they have made videos and posts about it I'm not sure what it dynoed at though but I'm assuming it made an extra 100ftlbs and hp over stock numbers. Figure close to 480-500. The problem is you cant get to much boost out of a stock motor without it blowing up I think most guys are running around 5-6 psi safely. If I had the money which I dont I'd build the motor first and then run 20psi or more lol.

+1 on a S/C for a DD. If you keep the boost reasonable and have a conservative tune you will have a great SS...my SRT8 is my DD and I have the Vortech on it. almost 1000 miles and no issues and that is still on teh canned Vortech tune.
Call BMC Performance if you are looking to get Blown...thats what me and Landshark did ;)

Figure right around 500 RWHP on a stock SRT8 with 5.5 PSi and a conservative tune.

[zoomzoom1]

I know......(opens wallet.......mothballs fly out.....empty) Thats why I'm asking about with a stock SRT...I put enough money into my TB for mods, Just that the SRT has alot of them already, maybe corsa and midpipes with the SC....hhmmmmm....

[THE Saturn 5]

I've seen a dyno graph on lxforums of a Vortech on an otherwise stock SRT8 w/ Vortech canned tune - 472 rwhp, 440 rwtq.

Turbos are more efficient, sure, but if you have to mount them in back, how much extra weight in piping are you looking at? Two car lengths of extra steel piping doesn't make me think efficiency. The Vortech kit was easy enough to install. I had done almost no automotive mechanic experience until early this year, and I managed to install the kit by myself in a weekend with basic tools and beer for energy.

[SuiSRT8]

Just got my kit finished on my SRT8 and the numbers when the car was running warm was 480RWHP with 460lb Torque, and when it was running really hot I got a run that was about 15hp/ft lb less so when the car is running cool it definately gets close to 500RWHP easy. All I have is catback and the Vortech nothing else.

those numbers sound pretty low for a blown srt. I am no expert but from what I have seen.

Vortech tune! And I think those are considered good numbers for an SRT8 on the Vortech tune.

What dyno was this on?

Do you know what yours dynoed stock?

Congrats, that sounds like fun!

[SuiSRT8]

I was 380 stock with catback and CAI, and after was right at 480, so 100hp at the wheels, and the dyno was a dynojet but I dont remember the exact name.

[SDChargerSRT]

Cool. Thanks.

[FloorPizza]

That's actually not too bad.... Remember that most stock SRT-8's are dynoing around 360 (or there abouts) RWHP. So getting anything over 460 is *more than* a 100+ HP gain, due to drive train loss. I believe the usual rule of thumb is 20 hp gain per 1 psi of FI. So getting a *net* of 100 hp (to the wheels) on 5 psi is very good. And when you consider that the canned tunes are conservative, it's *very good*.

[BAD MAN 485]

true but when you have landshark at over 500 with a r/t its kinda sad to see the srts under that number.

He has heads and a cam, lets talk apples to apples........

[BAD MAN 485]

true but its an r/t so if you take a a r/t slap on heads and cam and then take a srt are you about even? Then slap a blower on each and the r/t is more power? Either way the srt cost more for less hp.

[SuiSRT8]

Its not quite that simple but landshark is also doing his best to push the bottom end internals to their limits, and most of us SRT8 guys with a SC are not looking to push the bottom end till it blows up

Oh i could swear he said he was running 5-6psi. Well then thats another story. I know the cars are capable of making much more power it just wont be safe.

[SuiSRT8]

Also for what it is worth, I am getting about 22MPG out of my ride now where I was only getting 18-19mpg, and I still lay into it plenty.

Very nice numbers! Couple questions... what were your stock dyno numbers, what SC kit are you running, and do you have a CMR tune, or is the above chart the result of the canned tuned you got with the SC kit?

Those numbers are very sweet... so much so that I'm really interested in finding out the answers to the questions above to help make my SC kit decision....I'd love to get results that match yours.

EDIT: never mind ... I found your other posts with the before and after dynos. It sure looks like the Vortech kit is the way to go right now.

[SuiSRT8]

Before was only a Mopar CAI, and zoomers catback, and the stock numbers were 380 to the wheels, After was canned Vortech tune nothing less nothing more, and on a nice cool day with the temp on the car where it normally is its definately possible to get around 490 to the wheels. Vortech is the way to go.

[driftsucky]

So, BACK to the 5.7, anything over 75hp gain is good for me. I mean, realistically, I'm not doing it to race. I just like the power. If I get to stock SRT numbers, I'd be okay with that. Again, I'm not trying to spend 10k on the motor just to have to constantly be into it.

As far as tubro vs SC efficiency, there's no difference as far as I'm concerned. There's a difference in power delivery, but it's like 6 one way; half dozen the other. I think SC get a bad wrap because many cars that come with factory FI are turbo'd and many aftermarket companies that AREN'T Mustang or Camaro driven tend to lean towards the turbo. But, just in my experience, SC's are just as reliable and efficient on V8's (if not more) as turbos. Once we get into the HEMI motors, or the 5.0's, or the 4.6's, or LS1's etc...you're in another realm. A realm that's been, up until maybe a few years ago, reserved for rednecks and bumpkins. But, with the Charger rebirth, a new crowd is opened up doing things to this car that they used to do to smaller cars. I think that's where these stigmas come from.
Either way, I'll probably lean towards SC just because of mounting. I'm really not comfortable with turbo mounting spots.

[plumfloored]

I have a Vortech on my car, I love in Phoenix, AZ today was 116 on the dash.
This car is my daily driver. I have logged over 6,000 miles on the car since the install of the Vortech. The car has a ton more power, and is a blast to drive. It never runs hot. As for Fuel economy in highway driving it has gone up. I useually run 84-85 mph and before the Vortech averaged 22 mpg, now it hit 24-25 mpg.
I am really happy with the vortech RWHP went from 275 to 414 on a 5.7 with just a 180 therm.
Also this kit can be installed with by anyone that is decent at working on cars, and if you chose the factory tuned option, you don't have to pay for a seperate dyno tune, or incure any additional down time. The kit includes everything one needs to install. This kit proved OE quality results.
Let me know if you have any questions.

well 414 is more then stock srt numbers so there you go.

Does anyone like Kenne-Bell make a twin screw for these cars?Sorry I come from a Mustang,GTO,GT500 background and usually only go centrifugal for hood clearance issues.Is that the issue here?

Yeah, by about 54 HP! Sweet bit of boost for the 5.7, for sure.

Great info in this thread.. thanks to the Vortech 6.1 and 5.7 owners for the dyno charts and information. Great stuff!

I think the twin screw is from RDP. I'm sure it's more expensive, a lot more if you think $3000 is a lot more.
