Which supercharger????Procharger or Vortech

[corys69ss]

I am in the market for a supercharger for a 502 with aluminum heads. The cam is 211/230 & 510/540 full roller. I can change the cam no problem for one better suited for this aplication (if needed). Comp. is around 8.75. I do not want to run a cooler right now or at all if I can help it. Hood clearance is also a concearn. 69 Camaro stock cowl. I like the idea of the blow thru Vortech, but alot of guys seem to like Procharger better. The car will have ps also. I think there is some modification to get that to work. What size headers?? Thanks in advice guys. Cory

Cory, I'm still undecided between the two brands as well, but here's a thread that might help.

Thanks Dan, looks like the Vortech might be best for me. Around 8 psi with no cooler. I would like to know for sure about hood clearance, also would a 118cc chamber aluminum head be better than 110?

[dhardison]

Cory, yeah I've been leaning more toward the Vortech as well. I don't have the facilities for fabricating a lot of bracketry and such so the 'kit' appeals to me at this point. I'm concerned about hood clearance as well. Here are some other links that might be of interest to you.

I'd think the 118cc heads would be better to keep base compression down.

Also the 118 heads may keep the valves unshrouded a little better.

Thanks guys

We can get you either one. My choice is procharger. If we can help, let us know.

Frank, any specific reason(s) you prefer ProCharger?

Thanks,

what about using Procharger with the Vortect blow-thru, no intercooler???

Well, I guess because I am a horsepower junkie, and ProChargers simply make ridiculous horsepower. But technically, ProCharger continuously prove they have lower outlet air temps, allowing more boost with a given octane. Also, boost for boost, in other words, 10lbs VS 10lbs with another blower, ProCharger always wins proving they are simply more efficient. Also, the ProCharger is self contained, so it is truly a bolt on, NOT requiring a hole punched in the oil pan for installation. Lastly, in my experience with Vortech, and talking to their people, their HP claims are out of line with general science.

I do not really have anything bad to say about Vortech and quality; I think they are both good blowers. I am a master distributor for ProCharger, and have a operating agreement with a Vortech master distributor, so I could get you either brand for a good deal.

Because everyone gets numb to whatever horsepower they have, and because a pulley change makes it so easy to add some horsepower. I always like to see a buyer get a bit too much blower so the blower is not working to hard, and for possible growth, or even to have if maybe for another project. My recommendation for a blower for both of you would be a F1R. You'll have to call for pricing, but basically, it will run about the same as the V7 YFI, and is capable of twice the boost on your size motors. You could get by with a D1SC if you really think 800 range HP is all you will ever want, and you can save some money that way also.

There are some aftermarket hats available that work killer

cory69ss -
I agree with Frank. Similar to our discussion on "the other board"

[corys69ss]

Frank, I will pm you to get a #, I would like to give you a ring tomorrow. Cory

I have a Vortech with almost 20,000 miles on it that I am very happy with and it still makes 15psi. The issued mounting plate flexed too much and a steel plate was fabricated, after that no problems with the belt. I also am running a cogged belt drive which combined with the blower give the car a very tough and menacing sound even at idle.

Hey Mike, how many cubic inches is your set up?

But technically, ProCharger continuously prove they have lower outlet air temps, allowing more boost with a given octane.

Frank, I have never seen anything that 'proves' this. Procharger doesn't publish compressor maps - Vortech does, so I have nothing to compare the two.

I do know the YSi blower is one of Vortech's most efficient blowers at 79%.

Here's their YSi map:



How much boost are you thinking of running?

Jim

PS I'm very happy with my Vortech V-2 SQ S-trim. I just wish I had know they make a V-2 SQ T-trim. Mine maxes out at 7.7# of boost after the throttle and FMIC. Still good for 723/692 on my 383, at the crank!

[ProdigyCustoms]

Jim, at only 7.7 lbs, they probably are not much different. Where the problems start is when trying to run a lot of boost on pump fuel, or just running a lot of boost period. Especially when trying to force 500".

[DeltaT]

The problem is that Cory doesn't want to put in an intercooler, so he's going to run into a boost wall pretty quickly on pump gas. Blower efficiency will help keep outlet temps down, and his 8.75CR will help, but I don't think he should expect to run more than about 10-12lbs. on pump gas.

I'm still wondering how you can state that Procharger has "proved" they have lower temp output per pound of boost. Without a compressor map, there's no way to tell except controlled unit testing. I find the fact that they won't publish maps to be suspicious - like they're afraid they won't measure up.

Cory, what are your boost goals and HP goals? Are you dead set against adding an intercooler?

Jim

[corys69ss]

I would like around 850 to the ground, but if a can harness that I might (or shall I say will want more!!!!). I'm not dead set against intercooler, but trying to keep cost down. I,m doing alot to the car at one time, so my budget has taken a back seat to more power. I don't want to short change myself for future improvements. Keep the info coming. Cory
