Procharged 440?

[HYRDGOON]

Hmm, that is interesting.

I have been mulling over turbo(s) or centrifugal setup. A big question I have is reliability of the centrifugal on a street car, for example the d1sc? I seem to find a lot of used ones listed online that "just came back from rebuild".
I have had turbo cars, screw type supercharger cars, but have no experience or no friends that have ran a centrifugal, since I am considering trying one out I thought I would ask here. How reliable are they on a street car, mild boost, 8-10 psi? How drivable are they with a blow thru carb setup?, throttle response ect?

What you're proposing is exactly what I'm doing. I have a D1X that will be running through a C&S 933 CFM Blowthru aerosol (awesome for drivability I've been told) on my Stroked 440. (522 crate) and plan to run around that 8-10 psi (BUT NEED TO LOOK AT THE WHOLE PACKAGE AND WHAT I WANT TO ACCOMPLISH AS ADVISED BY HEMIRUNNER)

The smaller blowers are very reliable and drivable. When you get to the F series blowers they are insanely loud on a big HP combo and make long hauls really annoying. If set up right, throttle response is instant. The SBF we did goes from idle to John Force burnout in a fraction of a second.

I'm waiting for the "Mad Max" version of this!!

Mad Max version meaning you can turn it on or off? lol! I'm glad to hear that opinion of the F Series because seeing all the big blocks run F's I get a bit curious if my D series is up to the task but what I'm attempting is relatively mild (compared to the big boys) so I think it's probably the better choice.

I wish I was closer to you to give you the $$ and let you handle the build details... so much to absorb!!

Damn interesting for sure, helps for freewheeling & less backed up boost & pop-off valve issues
especially with boost when getting out of the throttle, cool idea for damn sure

Thanks for posting that...

I thought it was pretty cool too Budnicks! Solves that problem of the cogs being hard on the head unit from harsh start/stop yet gives the positive traction without working about slip with a serpentine.

As you would say... "Me Likey!"

Cheers!

Not exactly "pro-touring" but cool none the less

That is a fast fish!

A bit of a setback. Had the engine out of the car and after close examination - this block will not be boosted. Ever. So new block it is :/

That's a kick in the nuts but I guess it opens up some options for the new block. Any immediate thoughts of what you'd like to lean towards?

 

[Dreadl0ck]

Well, I guess it's better to find out now than before spitting out valves so...

No not right now. One part of me want to put a built gen3 hemi in it since I've worked on that engine a lot and know it really well from my Magnum build - but I think the conversion is a real PITA to do... Another part of me is looking at the same one as you got.. I think I'll be busy with the Alterkation front end and Lynx rear end this winter... not what I had planned for though.

Sounds like my combo will be even milder than yours. I am planning of boosting a stock low compression rv 440 bottom end, so I can get more than 200hp out of a 7.2 litre engine.

From some digging around on the net, the D1SC and the P1SC are availabe with helicut gears so they are "quieter" which would be something I would be interested in for a daily driver setup. I wonder how much quieter?, like unless you are on the gas, you can not tell you have a supercharger or below a certain rpm it is not noticable?

The direction I intend to go will be "old school" as well, so a blow throug carb would be in the plan. It lookes to me the first modification done to these carbs is cutting off the choke tower, how do these blow through carb setups start cold, lets say if it is just a few degrees above freezing? The roots type blower I had a few years ago had a suck through carb setup with no choke, but started fine I think because of the blower warming up the air and force feeding the motor, I assume, I had to baby the throttle for a few minutes but that was all.

When I get closer to sorting out what I want to do I will start making some calls to these companies about these carbs. I agree, it is best to look at the whole package and keep in mind what you want to end up with. I will most likely be posting engine questions ect.. and asking for suggestions when I narrow down which direction I want to head.

Good info,Thanks.

I can't say that I've ever fired a blow through procharger car at sub 50 degree weather. With a smaller blower, i wouldn't expect to see huge swings, but with the big F2 stuff they seem to need a fair bit of tuning just from 65 degree weather to 80 degree weather. From a power producing standpoint, I'm very impressed with the blow through Procharger setups, however, there's a bunch of reasons why my big power car is going to be turbocharged and fuel injected.

 

[Dreadl0ck]

I have had both helical and straight cut gears on my magnum. Here's a clip of it running with helical gears

and from inside the car

https://www.youtube.com/watch?v=E_c0ZVXsoXk

So yes - you can clearly hear the wining and the stone crunching sounds from the blower even if it's helical - but it's a lot quieter than the straight cut ones

 

[Hemirunner]

That's much quieter than the straight cut units.

Well something to update at least, Thanks to another awesome member Average Joe with the crazy yellow Charger I scored an awesome deal on some of the parts I'll be needing. Joe has decided to give EFI a try (and hopefully will update this thread with his experience/recommendations) and I managed to get a deal on his whole fuel system.

So parts acquired to get me one step closer:

A2000 Regulator- 13202

Magnafuel Pro-tuner Fuel Pump-MP4301

MagnaFuel Fuel Filter- MP-7010

CandS 933cfm Blowthrough


So that makes the list a bit shorter... parts I'm still looking to pick up are;

Extreme Velocity Pro Series carb hat
Blower Cam (Likely just have hughes grind me one to similar specs of Joe's or their recommendation)
Intercooler
MSD 6AL 2P
Single Plane Intake (Edelbrock Torker II or Holley Street Dominator?)
(possibly water/meth injection)



and a few other small odds and ends

 

[Average Joe]

Awesome Mike!!!! I am glad to see that everything made it to you safely.
I did get the injection on and got the car to fire last night but the charging system wasn't working so it wouldn't run very well. I will be putting a thread up next week after I do the Dyno. I will keep a look out for any of the other parts you need.

Which efi setup you going with Joe?

 

[Average Joe]

Which efi setup you going with Joe?

I have the F.A.S.T XFI Sportsman throttle body.
I went this direction so I didn't have to pull the manifold off to have it drilled for injectors.With the Xfi I can change it to multipoint later if I want.

 

[HYRDGOON]

The shopping list got shorter! Knowing the 747Mopar was coming to Canada to stay with me this weekend I took advantage and had some parts sent to him to save shipping & customs charges.

Now have my Intake (went with the Torker II) MSD 6-AL-2 programmable and my Extreme Velocity carb hat.




I think everything else remaining will get bought when the process starts. As long as I can keep up with the Overtime and save up for labor should get done this winter (fingers crossed)

 

[Phil McGrath]

Just wondering guys(MrSF and Hyrdgoon) how much air do your heads currently move? And how is the current exhaust system set up?

 

[HYRDGOON]

I'll try and dig out the flow tests from my heads they're buried under other paperwork right now. My exhaust is 2" Primaries Doug's Headers to 3" H-pipe, dynomax ultraflo's and out the rear. At some point I am likely to add the Doug's electric cut-outs

Something Hemirunner said came to mind when reading an article the other day. In talking to people I keep hearing them say I want an F1 or F2 ProCharger.... Here's some food for thought

"Perhaps the main disadvantage with centrifugal compressors is that they take quite a bit of power to drive. When dyno testing, Steve Morris found that an F2 needed 353 hp to make 32 psi of boost, so the engine that the F2 is being installed on better use that airflow"

I also made the official decision to add Meth injection and ordered a kit for my application this week from Snow Performance. Wanna do this right!

We've been 5.40's at 137 in the 1/8th mile on our 6th pass with the F2 427 SBF and we still have converter issues to sort out. Haven't even started to tune it. It'll go high 4's before it's all said and done. The F2 is a great race blower. Having said that, I wouldn't put an F2 on my worst enemies street car if it's one that he plans on putting any real miles on at all. If all you want to do is be badass at the local cruise in, by all means, order up an F series. If you really want to drive and enjoy the car, stick with what you have.
