OK I have made a firm decision to supercharge my n/a the way zBrown did. I know its not perfect, and not efficient but its cheap and effective. I just wanted to ask some questions about preparing my car for this.

I understand that i need a much more free flowing exaust. I was just about to order a rb header but if im gonna need something bigger next month i wont. Is there any company that sells 3" headers? Would the rb be big enough?
Also when ti comes to fuel. I already started saving twords my safcII. Will that be enough or should i go for a walbro and bigger injectors.

I also have a question about superchargers and xbrowns setup. This may eb dumb but im learning. How does the intake and intercooling work. I dont see either on the pics ive seen.

 

That's because he didn't use an intercooler. I'm not even going to bother arguing why this is such a terrible setup, you won't even need more than the stock exhaust manifold with how little it will add.

 

I know he didnt use an intercooler, i asked about the intake as well. It seems to be facing a wall. I dont see any type of intake piping.

OK i understand that this isnt a great design but for the $500 it will cost me and these ease of intsall, Not having to completely reinvent the long block of my engine yadda yadda, Ill give it a try. I already got everything including the welding priced down to a fixed number except the actual m90 since im getting it on ebay. Of course i do not have unrealistic supercar expectations but from what was said and the thearetical principal of it it must give a hp gain that cannot be beat for the price. I simply cannot spend $3000 on a camden or spend months and hundred more relocating my Tb and remodeling parts of my engine.

 

Well, the problem is, A) you're going to kill economy B) you're going to need at least two bypass valves c) you still have to invent a custom intake plenum for the supercharger (which is just as hard as relocating the TB) D) the cost of an S-AFC and the charger is over $500, not to mention the piping/belts/custom pulleys/etc (i hope to god you don't make the mistake of using vbelts?) What exactly was said? There was never a dyno or a number given for zbrowns car, nor was there much in the way of theory. I'm just curious as to what you are expecting.

 

I was already planning on buying a safcII for my n/a so i do not count it twords the cost of my sc setup. It will cost me considerably less to fab a plate/inlet for the tb than it would to relocate my tb. Rather than fabbing a outlet like zbrown i am going to modify the t-birds outlet, it seems more efficient that way. I would be happy with even a 20 top end gain. But what im hoping for is torque. I am unsure what numbers to hope for but anything decent will make me happy. And i look at it this way. If the setup doesnt make any type of gain ( i doubt) i can simply remove it. Resell the supercharger and not lose soo much money. Seems easier, simpler and safer than spending thousands on a proper fc or turbo setup.

 

can u post a link to the other guys supercharger setup thread?

 

Using the t-bird outlet is going to be difficult since it doesn't point in any direction that makes it decent with that sort of setup. I mean the *easiest* way would be to relocate the TB keep the n/a manifolds and just run the charger into the dynamic chamber and have a bypass built for your custom intake plenum, that could be fabbed up fairly easily. I've often thought of even building an air/water intercooler that bolts right to the top of that thing and then having the TB outlet ontop of the intercooler and running it directly into the dynamic chamber. Either way, you're going to run into a lot of customization trying to get a bypass to recycle all that air.

 

Ok now I'm confused...you state that you understand the possibility for large gains is slim, yet you're looking for 3" headers!...didn't you also say you were looking for torque???? Hint Hint....wide open exhaust = decreased low-end torque. Your question about fuel is also difficult to address because there are certain variables that you need to account for other than simply "I'm going to *throw* a supercharger on there" For instance, how much boost do you plan to run? Also, have you had your factory injectors flow tested, cleaned, pulsed etc... Do you even know what your factory injectors load is, in terms of percentage, under factory settings? Believe me, when operating properly, a factory injector is capable of pushing much more fuel than it ever does under factory settings. Also, how much do you know about the S-AFC II? The more you learn about products before you purchase them, the easier it is to assemble a good combination of mod's.

 

my issue with that is I dont have the slightest clue how to relocate a tb. I searched google and here and even pm'd you and found nothing. So its seems that piping through the tb will be the easiest way for me.
Im thinking now of talking to the shop that rebuilt my engine but I am not sure if they would be willing to do something unorthodox like this given the fact that they would be responsible. I am also looking into aftermarket tb assemblies. SOnicRAT, would the m90 be ok to do what you did? I would still be interested in pics, descriptions, and dynos of your seup.

As for the guy who asked why i wanted an exaust when expected small gains. Simply, more air and fuel = more exaust. A restricitive exaust would hold back any gains possible.

 

If you're going to do it, do it right. Otherwise leave your car the way it is because the gains will be minimal.

 

Thats what i am startign to realize. I just got a bit hype about the ease of zbrowns setup and didnt realize thta i dont knwo hwo well it works. If i can do ti right, liek sonicrat describes for under $1000 in goin for it. If not....

 

Well, basically you just get someone to make a flange that fits the supercharger, get them to weld a pipe on it that directs it somewhere accessible, then on the end of the pipe you make a flange that will allow the TB to be bolted to it, and that's it, hook up the TPS and run a new throttle cable.

 

OK, im trying to clear up your description. Ill get a plate with an outlet welded like in the pic below, but rather than piping into the Tb. I pipe into a kind of insert that is placed between the TB and the manifold ( maybe wrong terms) like the pic of the atkins kit also below.

 

Ok, you see on the back of the supercharger in zbrowns picture those two hoses & clamps that seem to wrap around under the vehicle? That's the intake. What you could do is put the TB on the end of that, and then put the AFM right on the TB.

 

So I would put ti where the green in in the pic and pipe the output of the sc right into where the Tb once was. WOudl the sc still be mounted in the same place as the pic or will it work mounted on top?. I think it would fit with a flange but am unsure about a belt to run it. Also if the tb is on the intake does that mean I have to run lower boost since I cant use an intercooler? What kind of numbers are you seeing with this setup?

 

Yes, you'd make your own version of that intake plenum (which is basically where that green is), and you'd reroute it whever you wish it to go (or it fits best), then mount your TB on the end of that pipe, then route the output directly into the dynamic chamber, since it's not intercooled you will run a pretty low boost, but at least it'll be in an 'efficient' manner.

 

Lol, I haven't been in this forum for months. Is everyone trying a supercharger fab job these days?

 

So running this efficient setup at low boost(bigger pulley) will be more effective and produce more available power than running high boost through the TB? Also, have you ever gotten your setup dynoed? What kind of gains can I expect from this? What do you consider low boost?
The way ti stands now i think i can make it simpler by buying a m90 with the tbird intake and output and then cutting and welding them to new piping cutting on labor and cost of fabbing totally new flanges.

 

You seem to be misunderstanding. You'll run the same boost through the TB as you would if you relocated it. Either way the thing isn't intercooled.

IntegraLS: Yes, it appears to be, this place tends to be trendy, first turbo n/a's, now supercharged n/a's, yet not many people seem to have a clue of what's they're doing.

 

ImprezedRS:

Hell yeah, its the new trend in town (at least since I have been here ((August))).

 

It's kind of sad. It's so much easier to buy a TII in the first place. People want cheap power I guess so they look into what it takes to hook up a blower or turbo, because they're cheap on ebay. Kind of like how the FD is a cheap exotic . .

 

if your gonna do anything do it right... Kinda interesting to see this new trend twoards superchargers

 

Well, it is cheap, but the problem is they don't understand it takes knowledge to do it that makes it cheap. They're like, oh, he bolted one on and it worked, i can do that for $30! So then everyone jumps on the bandwagon. </end threadjack>

 

LOL, it is a neverending quest to find that magic "high power with little money" idea that nobody else has figured out.

Nobody with a clue would choose a 55% efficient blower over a 75% efficient and intercooled turbocharger. Therefore, it's not about having a clue, but rather it's about a learning experience.

 

Imho I think its just people wanting to be different. Plus in alot of the areas a TII is a dime a dozen. I have yet to see one (other then mine) in my area.

But to each their own.
