N/A Supercharger Project x2

So what is a voltage clamp? Is it a resistor that you put in line from the MAP sensor?

Looks like some more research here Taza lol

More or less, yeah. I don't know the exact inner workings of the circuitry but it does basically act as a resister that is spliced in between the MAP and the ECU.
 
Awesome stuff. Gimme a shout if you need a hand with the install.
I've become some what familiar with the Subaru engines bays after doing two engine builds in 2 months hahah.
 
It would most certainly have an effect on both I would imagine.

Another thing that may be worth considering is upgrading the brakes. The standard brakes on a Forester are pretty dismal and with the extra power you may find yourself in need of better brakes. Spose, that depends on how you drive it.

Might also be worth keeping an eye out for a spare gearbox. Subie gearboxes were made out of glass it seams. The sudden torque from a supercharger will certainly stress out the drivetrain, especially offroad.

I don't plan to having it running all the time, mainly to preserve fuel consumption. Just when extra power is needed, as current overtaking is almost impossible in my foz with the larger tyres and offroad wise I am unable to hold my revs on inclines. The extra torque for taking off from a stand still should also make a huge difference.

I am just going to start off with the basics and as/if more need to be done, ie. brakes then I will do it if need be.

I should have similar power to the EJ25 N/A but more torque and especially more torque down low. The gearbox should be fine for this task if im not hard on it.

Yes very good point mate.
Not being able to stop in time is the last thing that you want to happen. Especially when you punch it & decide to give it a bit :twisted: :ebiggrin:

Especially as his insurer will most likely not cover the car with an off the books and non blueprinted supercharger install :poke:

Not going to bother telling them. In a few years time it will only be insured for $7000 or there abouts so im not really worried. To get it engineered whether the brakes were upgraded or not would be onwards of $1000 probably so its not worth it.

Be careful mate, be very careful.
The last thing you want to happen is for your insurance to not cover you, should anything happen.

For example if someone rear ended my Forester, then I wouldn't see it being an issue as my supercharger would have nothing to do with it.
Its more if im going too quick and am unable to stop intime that I see the S/C beiing the issue.

Like I said before, just be so very careful.
Even if you tap someone in a slow speed/impact rear ending accident, it can be very expensive these days.

Also, if it's not engineered, how would you go when it up for rego ? Maybe another thing to think about too.

I don't mean to be judgemental so please don't take it to heart mate :neutral: It's just that I'm trying to look after your best interests thats all :)

EDIT: I really do hope it works out taza & I'm sure it will :biggrin:

We don't have any kind of inspection over here in WA when its time to pay the rego. Usually just pay it online and your done :) Nice and easy.

I know what your saying, I found a local consultant on the Department of Transport for WA website and sent him an email just then asking a few questions. If its not alot to engineer it then I will. The brakes will probably need upgrading for it to pass though.

They will go through the car with a fine tooth comb. You'll need a brake test (from a brake engineer), emissions test on a dyno, plus everything that's done on a RWC taken to the extreme. It can be done but make no mistake, getting a car engineered is not easy...or cheap.

I'm not trying to talk you out of it, just want you to be ready. If you can afford it I think it would be the best thing to do.

insurance companies dont care about logic, they just want any excuse to deny your claim. If you were in any accident & you havent told them you would need to remove the blower before any inspection.

Even just adding non-standard wheels requires you to "disclose" this to them. There have even been some cases which went to court cos the insurer denied a claim, eg, due to an undisclosed aftermarket stereo! The claim won but it needed to go to court!

Again, I'm not trying to put a dampener on your project, just be aware of the complications... ;)
 
^ Thats a load of cr@p with the stereo!

Not going to bother with the engineering but it doesn't hurt to find out some infomation on it and whats involved.
 
I don't know the WA laws so I'll leave that alone. Brake diamater on early Forries is a worry. But you can easily upgrad brakes. Easiest bet would be later model Forrie brakes. Then there are WRX brakes which have the same size disc as the later Forries but with 4 piston calipers- until the MY08. One of the H6 Liberty's came with bigger brakes again- not sure though if they will fit under 16" rims. Pinging might be an issue with a standard ECU and with standard petrol. 98 might be the go. I wonder how the stock ECU will handle it. If you run an intercooler it might work even better.

Thanks for the info Rally. With the modifications on your WRX have to had to get it engineered or anything of the likes?
 
No need for engineering as far as I know. The rear calipers were available on the RA version of the STI, and I am still using the original 4 pots. The brake lines are approved. The gearbox uses the existing mounts. If I put a 2.5 litre engine in it I would have to get that engineered.
