Liberty 3L H6 supercharger kit world first

  Top of Page

Hi Guys, we are looking at developing a supercharger kit in conjunction with Raptor superchargers for the Liberty 3L H6 engine. I have always wanted to do something like this with the flat 6. Now with 180kw we are looking for a 300kw end result or better depending on how it responds. We will look at intercooled and non intercooled versions. My question to you all is do you think there is a market for this kit. you can buy an 05 liberty 3.0r B for $27000 with the STI 6 speed and I think it will make bulk torque. The kit would be around $5000 depending on what problems we face with injectors and pump. I am ready to buy a liberty to start R&D as we have just started a new subaru business in Mackay called Subaru Solutions. Can you give me some feedback please, this is not a guarantee that we will proceed but no one in the world does anything and it seams a waste, Thanks for you feedback

Have you looked into things such as the compression ratio these engines run?
with that kind of compression ratio I would imagine it would be a nightmare to tune once you started boosting... got pre-ignition ? LOL.. good luck with it all and really really hope that something comes of this that works....
Sounds good.

without running methanol or C16 your going to have problems with the high compression ratios these engines run.

but if you can get a 200+ kw (at the wheels) kit, youd probably sell a few around that price, providing they retained general reliability

They run 10.7:1 same as a HSV or FPV GT and they blow them so it will be 6 or 7psi. Nothing is to hard if you want to do it.

Make up a full turbo kit instead.
Supercharges are OK on larger displacement engines because of the torque the bigger displacement has on tap from the get go.
But with Turbo's you can at least get full torque when the turbo reaches max boost, instead of waiting for the supercharger to get up to max revs to give Max torque.

Just add twin turbo's then well over 250KW!!

A small raptor in a B4 would be awesome for the mid range to fully eliminate the VOD, but there's no room in there for it...

Not really a "World First" either, COBB did it years ago to the 3l Tribeca engine.

Turbo would be good but it gets to dear and things get real hot under bonnet. You need turbo drain and **** loads of pipe work. Supercharger has no oil supply and is cheap. Cobb did not sell there kit did they just did a one off. Anyway this is for Australia for us here just looking for interest

Oh no.


Not another one of these ZOMG threads.

I call BS on 300kw. Big time.

Look this is just to guage what people think, Im not worrried about room yet as where there's a will theres a way. If you all think it's a waste of time than we will scrap the idea. Raptor already does a NA RS blower kit here in Aus and it hangs off to the side so the H6 takes up the same amount of room as far as side ways goes it just longer. The rule of thumb is that 14psi on an NA engine usuallly doubles power. So 14psi would be 360kw so 7psi would be about 270kw so our goal would be 300 with some tuning and the fact that 200kw is achieveable with STD engine with a tune. Can anyone imagine what 300kw in a liberty would be like with a high flow exhaust and a boxer 6 growl. I am alittle surprised that you guys aren't keen on this

Put a turbo on it, not a supercharger.
The extreme majority of subie driver's like the lag then kick, and don't want something that sounds like it would be on a commondore.
Japanese cars are supposed to be turbo'd.

How many RS impreza's are actually running with a blower?

I reckon it may be worth a try...

But before I (or anyone else, I am assuming) would hand over any hard earned dollars I would wanna know a few more things:

1: is this the first time you/your company has done anything like this?
2: what testing has been done?
3: what back-up service/warranty do you offer?

I think everyone should stop knocking this fella because he wants to try something different, as long as it is done properly, it MAY turn out to be something that is a little different (isn't that why we drive Libs not Commanwhores?) and think of that exhaust note! lol

just my 2 cents worth

Our company is a HDT dealer and we have a mainline 4wd dyno, we have fitted plenty of blowers and turbo kits. This will be our first go at such a task. Raptor superchargers has developed a blower kit for the NA RS as in his words " I make the blowers already so now its just a matter of making fitting kits. I have never seen an engine that can't be forced inducted. You name an engine and someone has blown or turboed it. If we all agree that the subaru engines respond well to boost and the H6 has variable cam timing and timing chains instead of belts. They also have high strength conrods similar to an STI conrod and shot peened rings. I reckon the H6 has been left by the way side. You search the internet and there is nothing on them. The kits will be like most blower and turbo kits, it will have all the parts required to do the job but it will be your responsibilty to see that it is correctly fitted and tuned. I maybe just do a one off for myself and see how it goes, at least i will get to enjoy the torque and surprise a few people on the street.

That black RS impreza ate engines for breakfast. It was killing engines with 8;1 compression let alone 10.7:1.

The rods are a lot smaller than STi rods. The pistons are not very strong and will not take any detonation. The fuel system is returnless also so some reg fiddling would be required.

If you can get a reliable product on the market then it will probably sell well. You will have to sort the tune as part of the kit though(a good safe base program) or there'll be dead engines everywhere. They are kind of complicated and expensive to fix too.

Personally I think centrifugal superchargers are rubbish but I can see that they are a much easier thing to package as a kit compared to turbocharging(which is far superior).

No I'm not talking about the black impreza, If you look at raptors web site they have a silver one here in Mackay that we tuned. The dynograph is on there as well and it was 124awkw i think. That would have to be close to a WRX. It has been going no probs at all. The black one was a raptor blower that the guy fitted to his own car. The silver one is developed by Raptor himself ans it is his daily driver.

a turbo would be far superior to a supercharger kit. superchargers, are only ideal if there is absolutely no space available. a garret gt28 series turbo would be killer on such an engine in a low boost application. when you consider the exhaust flow of a N/A 3 litre, there would be little to no loss of torque against a s/charger. with superior outright performance to boot.
i'm tired of people confusing linear power delivery with torque!

I think some of the repsonses you have recieved are from immature NEVILLE's who a are simply lacking knowledge.
Its true, there is nothing out there. There are plenty of H6 enthusists out there. They have all had to settle for small tuning gains either by aftermarket mapping or sti v-tune. In both cases 10% is it. I have visited STI and the demand for tuning is high.

If you do it by the numbers there is a market, not all sube drivers want a boxer 4 turbo hit, hence why the maturer drivers own h6 fitted liberty's.

Go for it. What a performance bargain it would be.

Cheers, Mark

i drive an H6 and despite the fact that i could make more power with a turbo, i like being able to pull a car load of people up a hill doing under 2000rpm... a supercharger kit would enhance the already powerful torque curve of the H6...

besides i love the sound of a supercharged engine

i for one would put up my hand for a supercharger kit... but i wouldn't feed boost into the stock engine... you'd at least have to find a way to lower compression... (thicker head gaskets? or lower comp pistons?) [and i don't know how much power you could make on the {i think} 280cc injectors)

my car currently runs 143kw at the wheel in NA form (and i'm aiming for 150+ once it's retuned) and i'm very happy with it. i wouldn't want to turn it into a grenade that makes me worried about putting my foot down any time i want some acceleration.

i think that if you could find a way to reliably supply H6 owners with 200kw at the wheels for under $10k... there would be a market for it......

but probably not a very big one... the H6 is the top of the range model after all... people don't want to mess around with a $50k+ car if there is a chance it's going to blow up after the first 5000kms

just my 2c

Well due to the lack of interest we have shelved the idea for now. We may do it later on. We had the guy with the blower keen and he was ready to make the bracket as well but due to all the negative feed back why would we bother. We may look at this again down the track and for those not interested well who cares, it seams most of the responses were from 4 cyc guys anyway.

most mature liberty drivers that choose h6 fitted liberty's, then complain that they can only obtain 10% performance gains, should re-evaluate the reason they chose the h6 option over the turbo fitted model in the 1st place!

i would also argue(having either driven or been in,h6,2.5 na,2.5 turbo and 2.0 sti turbo) that the ez30r is a far more dartier and rev happy motor than a boxer 4.

Stop Valve bouncing your car at cruises, especially whilst stationary. You look like a retard. Not cool.
