604 and Procharger?

[Jarrod]

Hello Guys. I have some questions. I am seriously thinking of converting my Nitrous longblock to a Procharged application, but I am a supercharged newbie and I would need some help. I am seeking to make a serious level of hp with this new combo (1800-2000) and I'd like some recommendations from those that know. I know that the compression has to come down to a reasonable level, and some obvious camshaft changes but the rest of the combo is very new, very strong. This 604 would be used in a 3000 lb+ auto-trans, full chassis, big-tire car and I'm now looking to make some serious Procharged horsepower with it.

The questions are: for the HP level that I am seeking and the cubic inch size of the engine, what model Procharger would I need to go with? Can I achieve that kind of hp using a blow-through or is EFI a requirement at that HP level? Would an intercooler be mandatory? This would be an all-drag race type application so what should be my choice of fuels (gas or alcohol)? Basically what are the issues that I can look forward to when making this conversion over from my serious nitrous combination over to a serious Procharged combination.

At 604" I think 1800hp will be a cake walk. You'll need an F3 bare minimum. There are carbed apps making similar power out there, but they are few and far between I think. If you choose EFI and gas, an intercooler will be mandatory. Alcohol blow thru or EFI likely wouldn't need intercooling. If money was not an issue, I personally would have an EFI setup, intercooled on gas.

I'm FAR from an expert though. I'd suggest you talk to Steve Morris about having him convert you engine and get you all set up.

Money is SOMEWHAT an issue but not at the expense of the goal that I am trying to achieve. I have a goal of 1900 or so hp so I'd like to know what model Procharger it takes to get me there. The blow thru carbs would be a better money option for me, but that's what I need to know, if they can take me to the hp level I want to get to. If the blow-thru carbs won't get me there, then what brand of EFI would you suggest? I have no probs using alcohol being that this will be an all drag race application. Any other recommendations, tips or hints will surely help me out in researching this conversion before I make a committment to this new project. I definitely want to make this conversion, I just don't know many of the ins and outs of what i will need and I don't want to disappoint myself by having to spend my very hard earned money twice. Thanks for the help and I am surely hoping that you have more suggestions for me.

you can make that kind of hp with a blow thru set up easy.chack out this web site www.lutzracing.com (http://www.lutzracing.com) he has a twinn turbo blow thru set up and maks well over 2000 hp.

i was building a 572 bbf with a D3R - that unit will make well over 1900 hp easily- please check your pm...

Contacting Steve Morris Racing Engines was good advice. I personally have a 565 F3R blow thru carb gas non intercooled making the power your interested in. I too did have a 632 gas nitrous motor and down sized it for the blower. The longer strokes make it pretty hard to get a good piston/pin/ring designed for what your wanting.
If you contact Steve Morris you may want to look at his mechanical/alky injection combination he has worked out. In the long run you will most likely save money and have potential to make even more power.

I think if your real serious you could make 2500 maybe more F3-R is the only way to go I think EFI and intercooled on gas Big stuff or Fast XFI with the EFI. I don't know much about the blow through stuff. I really like the idea of a bbf with a Procharger

[Jeremy Glass]

At high hp levels the carb will not flow enough fuel and youll need to add injectors, or go to EFI only.

NOT TRUE.

Not really sure were the blow thru carb limit is....but recent CSU dominator advancements, you can make 2000hp on gas non intercooled.....for sure.

That is awesome.

Lutz's Blow thru on alky with no cooler went 2800HP. C & S carbs. From what I've seen and heard, fastest carbs CARS out there.

I'm currently running a 588 c.i. with an F3R. car runs 4.28 @ 170 and weighs 2600#. gas with intercooler EFI. Big stuff controlling EFI. Engine built by Doug at Pro-Line racing engines in Atlanta and tuned by Steve Petty and Chris Tuten.

try turbomustangs.com.

its not only mustangs.. youll find alot of info there

I own a 615 big chief nitrous motor can someone elaborate on the problems with long strokes and ring package problems associated with the possability of switching to something like an F3? I am interested in making a change to BOOSTED of some sort down the line (F3 or 106MM) and Id like to know more about this subject.
Maybe I will be forced to downsize my shortblock?

[Ron Clevenger]

With the Big Chief heads the chamber is pretty small and trying to get the compression down in the 9 or so to 1 can be difficult in locating wirst pin and ring package. With my previous 632 Big Chief'd motor it just didn't happen. So traded out crank for shorter stroke.
That's the basic's..........blessings..........Ron Clevenger.

Hello,
I will have a 500in BBC w/Big Chief's on the engine dyno in the next couple weeks . It has a PROCHARGER RR custom f-3 , Gas motor . Big Liquid to air ect. EFI.

I'll keep you posted on the out come ......I'm crossing my fingures for some good #'s .

[Jarrod]

Do any of you guys have an idea about what kind of compression I can run with a Blow-Thru application on Alcohol? How about an idea of the max. compression you'd run with a larger cube engine on alcohol using an F3R ?
