Twin Supercharger?

94s10cpi · 10-22-2009, 04:42 AM

Is it possible? Anybody have a twin supercharger set up? I was looking at Al's projects from the past at www.wynjammer.com and i saw a twin supercharger set up and it made me wonder if anyone has tried this with a 4.3 s10. I'd love to do this. This is an idea of a way from the current supercharger kits Al sells to do so. Use the bracket for the 4.3 1996-07 and the bracket from gm full size 1996-07. Does that look like it'd work? I'd love to know. Any ideas? I know a new bonnet would have to be made and i plan on getting the marine intake soon so i'll be good on the fuel side. Probably get a better fuel pump. What do you all think about this?

disturbing V6 · 10-22-2009, 07:52 AM

I have seen it done with twin ATI superchargers. Guy said he loved it. Not sure myself how well it worked.

94s10cpi · 10-22-2009, 05:35 PM

Shouldn't you possibly have twice the power or close to it? Cause of the more air going into your engine while still maintaining the stock psi that the wynjammer put out? Hmm i guess i will email Al and see what all he says about that idea.

12sws27 · 10-22-2009, 06:13 PM

Anything is possible. If you have the skills you can fab it up. I always wondered about it as well. It would have to be worth it though. What I mean is there might be cheaper ways to get 12psi besides 2 jammers and still sticking with a blower. Like a procharger or vortech. Then there's always Turbo.

I think like this, say a guy gets 2 jammer or has 1 already and get another at a real good price. Gets them on there and then wants more. I myself would be worried about spinning my jammer faster the what in takes to put out 8-9 psi. 10-12psi would probably more than enough for me but some guys go all out and might want more than 20psi. A good single turbo could do that. Just my thoughts.

94s10cpi · 10-22-2009, 06:22 PM

yeah true.. i kinda want something that no one really sees ya know. i've been just trying to find any sueprcharger kit for my truck and there aren't to many for sale right now that are used. i dont have the cash right now to go right out and buy a brand new one. i would also love to go turbo but finding the headers for the turbo is hard well i could always make some. but idk its just something that came across my head. lol if i could get any type of boosted power adder on my truck for kinda cheap i'd do it. and say f the twin supercharger set up. up i've never seen or heard anyone with that on an s10. I also emailed Al just to see what his thoughts were on this.

BudRacing · 10-22-2009, 08:04 PM

It's a waste in my opinion. Sure it'll get the WOW factor from people who really don't know much about it and all they know is that MOAR is better, but really in terms of effectiveness, there are better ways to do it. Also, no, it will not DOUBLE the power just because you have two superchargers.

The point of having twin turbo chargers is to reduce turbo lag by reducing the effort of the exhaust gases to spool the turbos. Two smaller turbos spool faster than one larger turbo.

Superchargers don't have this lag problem. They are effective as soon as the engine starts spinning fast enough to produce boost, which is usually pretty quick if not instant.

Disclaimer: This is what I'm logically putting together and have no citations to back this up. I'm a business major, not an engineer.

From what I understand, PSI is measured as pressure within the intake. One supercharger creating 9psi for example, would be equal to two superchargers creating 9psi. The only difference in volume would be the additional tubing required to run the second supercharger.

Am I wrong in this thinking?

raven2510 · 10-22-2009, 10:23 PM

you would be correct on that...just like twin turbos

I beleive you are correct if the superchargers are waste-gating at 9psi, but if they simply both push the amount of volume of air required to generate 9psi in the intake, then it should effectively get somewhat near double. however I don't know how the force from one supercharger would affect the other.
AS far as I know, double superchargers are just for show, and is probably less efficient. Looks neat as hell though

Saw this at a car show once:

disturbing V6 · 10-22-2009, 11:37 PM

If you had a split intake you run one charger per side of motor and in theory there would be less pressure loose since one charger is doing 3 or 4 instead of 6 or 8. On the 4.3L there are always two intake valves open at once. There for you would get 9 PSI in both cylinders instead of 9 PSI between the two. But you need the split intake to make it work effectively,.

rentedmule · 10-22-2009, 11:50 PM

There are twin S/C'd shelby mustangs and I've seen a kit for mopars as well.

It can be done but it's definately a total waste on a stock motor. Instead of having an extra 40-50 lbs hanging over your front end (a powerdyne is around 45-48 lbs) you'll have 80-100 lbs - that's equivalent to swapping in an iron V8 so you may need suspension adjustments.

One kit costs ~$2500 so if you go new you'll be over $5000 in just for the kits and still have a setup with no intercooler and headunits without a dedicated oiling system that aren't far from their tolerance limits.

It's twice as much maintenance and much less efficient than just buying a decent blower that will make 20+ psi. One headunit rebuild alone can cost $300+ and that's if you don't wreck any parts. If you have to replace an impeller you can be a grand in with parts + rebuild (ask me how I know!). Even if you need to do a pulley change to adjust boost you're talking $200 instead of $100. It adds up quick.

I'd buy a procharger kit for 5.7 vortec, bolt it on to your 4.3, plumb the intercooer, and have the same or greater boost capacity, cold air and infinitely more reliability for close to the same price as 2 wynjammer kits. That's just my opinion. Also turbo manifolds can be had any day for ~$300 - check syty.net or there's a set on ebay right now.

94s10cpi · 10-23-2009, 01:19 AM

thanks for the info guys..

yeah it might look cool but thats all it'd be good for just looks. just to show it off. yeah now from reading what you guys said im not gonna try to do a twin supercharger set up. i'll just keep looking for a used kit.

rentedmule is there a set of turbo headers on ebay? i cant seem to find them.

and to you all which is the best way to go for power by price? which is the cheaper way to go? supercharged? or turbo'd? and should i get the marine intake or would the upgraded injectors a better swap? man i need to look into this a little more lol

yz85608 · 10-23-2009, 11:11 AM

look at the twin roots style supercharged lightning on you tube.

cs xtreme · 10-23-2009, 12:13 PM

I would think two superchargers would draw more power to run than one.
the only reason i could think of to do two is if one was not big enough.
rotrex does twin on a lot of v8s because they are a smaller supercharger.
wheel 2 wheel uses them on ls1's
I guess they do pretty good.

rentedmule · 10-23-2009, 12:33 PM

I would find a set of sy/ty manifolds and go turbo if you want the option for lots of upgrading later for less cost. The cross-over pipe may not fit perfectly but the manifolds will bolt right up. Check UR50SLO's thread on his wife's turbo Jimmy build. He did the marine intake swap and turboed with stock sy/ty parts. He's got a few build threads but this was the first I came across: http://www.syty.net/forums/showthread.php?t=52886

It's a high mileage, full weight 4wd 4 door and it ran a 14.4@93 mph (in 4wd).

Manifolds

They usually pop up every few weeks in here too

94s10cpi · 10-23-2009, 05:09 PM

wow i dont know how i couldn't find those on ebay lol i typed in like everything i could think of lol thanks rentedmule.

how much power can the stock manifolds handle? should they be able to handle a name brand t70 turbo?

im a have to check out syty.net also thanks

rentedmule · 10-23-2009, 06:39 PM

They'll take more power than you'll ever need! Two local trucks are making over 600 HP, 750 Ft/lbs on stock manifolds and cross-over. I don't even think they're running vortec heads.

12sws27 · 10-23-2009, 06:43 PM

IDK how good they are or how much they cost but That company DTS that make 4banger turbo kits and has just made a V6 kit makes Manifolds. All I know is they guarantee their welds for life.

I'm curious has to which would be the easiest to tune for, S/C or Turbo?

94s10cpi · 10-24-2009, 12:24 AM

yeah i went to DTS's website i might just save up money and try and get there kit. "The complete 4.3L Stage 1 Turbo Kit is $3625.00 Shipped!" i guess thats not to bad of a price. and yeah i wonder which is easier to tune. i would like to have a supercharger or something to give my truck a little more power for when i get it all put back together and take it out next year.. i guess nitrous will have to do until next winter then its turbo time. i should have enough money saved up for that by that time. thats if i can save some and not spend it one stuff lol im only 19 shoot i dont really need to have one of the quickest v6 s10s in my area yet it would be nice but i can wait lol.
