Thread: Procharger ?

Tweet

I'm considering a Procharger F1R cog drive on my 427, Anyone with any experience with installing these, tuning, carb suggestions ? How are these on limited street use ? I've been doing some research and the power these make seems like the only way to go to make big power pump gas engines !

I'd suggest getting with either a tech at Procharger or one of their dealers.. I've been studying them too, for a "first timer" might be best to go with one of their systems that is upgradeable. Also seems important to have a cam, cylinder heads, and an exhaust system that is compatible with a supercharger..

Why the cog drive? Looks like to me the ribbed pulleys are more the way to go....

With the horsepower these things can add, also want to remember that a stock driveline and suspension probably isn't going to handle it....

I'm not concerned about the engine except for changing compression and cam everything else "should" be in order. The reason I want cog drive is I have a friend who had a Vortech on a 89' mustang efi and when he started putting some boost to it and some serious rpm it would burn belts and sometimes throw them. I've read a little about cog belts and it seems for weekend driving they are ok but tension is an issue, they can't be too tight and they have to be frequently checked.
Have you heard about having to cut on the corner of your valve cover for clearance of the supercharger?

I've found with foolin' around on Dave's 408 build that the power is in the intercooler. More 'cooler, more power with the same boost. When I worked for Caterpillar, we called 'em aftercoolers, but whatever.

hmmm... guess what I've read and Richard has done on virtual dyno's, the best power is below 6500 rpm and the more cubes, the better the power is down low on the revs... At least with the centrifugal blowers, with the roots type blowers, then the power goes up somewhat proprotionately with the revs.... My point is, why rev it if you don't have too....????? As for the cam, superchargers like an entirely different cam then normally aspirated....

As for cutting a valve cover, I would doubt it... Sounds like one more reason to talk with the tech department. I doubt a well engineered kit would require any cutting of valve covers for clearance?????

Some of the companies do call it an aftercooler, some an intercooler, and with the Ford EFI they have a charge cooler that is water to air..... Reading another book tonight Richard.....

I'm not saying your incorrect, but centrifugal superchargers need rpm to work, sort of like a belt driven turbo, where as the roots type blower make power instantly off idle. I know I've heard about the valve cover issues, but it may be on the larger units, I hope your right though for 4K for the blower plus 1K for a carb I would expect a true bolt on, not to mention fuel system upgrades.

Depending on your set-up a Procharger motor will make plenty of power off the line. As a matter of fact some have to retard the timing and bleed off boost off the line to keep from blowing the tires off. I sold my roots blower and am going with the F-2 Procharger because there's no way the roots unit I had would make as much power as the centrifugal will.
By the time I get around to firing mine up, everybody will have one.

True on the revs, but just how much power do you want and how much power can you actually use without just blowing the tires off and make the car almost undriveable on the street??? The rest of the components in the engine also have a lot to do with what RPM level you plan to run at. Even a track only car is going to need to limit the power to a usable level equal to that of what the driveline can withstand and the suspension can hook up....unless your just after a "bragging rights" dyno figure. Having 900 horsepower and using 900 horsepower would require that the rest of the car is up to the task.....

When I went to Atlanta a few months ago to pick up those flathead parts from Paul, they had this little baby in the shop. Is this one of the chargers you guys are talking about?

Don

yuppers, kind of a king sized version of what I want but along those lines....

That looks like the reverse drive F-3 with EFI. Very cool set-up.

That particular shop had some very trick stuff in there. All of it is foreign to me as my technical knowledge ends at about 1970 . Here is another one they had, I think turbocharged?

Don

Yup, I see one of the turbos with green tape over the inlet on the driver's side. Allot of the new stuff is going EFI over the blow through carb. The carb has a limit as to how much HP it can put out before it just runs out of fuel delivery capacity. They are however, coming out with newer dedicated carbs all the time for the high end H/P/ applications. I understand new blower carbs are going obsolete about as fast as computer stuff. A guy can get hooked on this stuff.

I'm sure the chassis of my car will hold the additional power and be able to hook up. It's been 10.20 leaving on the brake and 250 shot and has never had a problem, my street tires are 31x18.5 and my slicks are hoorier 32x14
D05's . Nobody has mentioned a reputable blow thru carb company, I've done a little research and it seems like the three big ones are C&S, The carb shop and CSU, and some praise one and bash the others anyone with personal expeirence ?

P.S. It's not bragging if you can back it up...Right?
