increased fuel consumption, also using a 1GZE SC is like using a stock trubocharger off a GTSt. Unless u go for a $6000 vortech/eaton centrifugal supercharger (which is like puttin a T88 on ya GTSt) you'll never get optimal results out of a supercharger.

The reason Nissan never came out with em is that in small capacity cars (3.0L and under) its not completely efficient.

if u do consider supercharge

the car will be be more like a 4.0L aussie six

plenty of torque and power, but power wont peak that high in the rev range as our cars currently do.

u can get SC that can rev and stay someone efficient at the higher revs, but it also cost money

not necessarily, those are the oldschool superchargers that work better at higher revs.

If you look at the boost charts, the turbo charger has an exponential boost (very low boost for initial phase and very high boost after the sweet spot). A supercharger however is belt driven, ie constant. It has a linear looking chart, therefore you'd have better midrange boost than a turbo, and much better pickup at the lower end. You do however have to tune it so you don't overboost at higher revs.

eg: say hypothetically your max boost is 14psi

REVS.-> 0 . 1000 ..2000 . 3000 . 4000 . 5000 . 6000 . 7000

SC.....-> 0 ... 1 ...... 4 ...... 6 ...... 8 ..... 10 .... 12 .... 14

TURB.-> 0 ... 0.5 .... 1 ...... 2 ...... 4 ...... 8 ..... 11 .... 14

however true linearity is only achieved by centrifugal superchargers (I think, not sure) and thems the more expensive ones.

Oh and as for the q about the ECU having to be modded... NFI, I gave up and decided to go for a GTR b4 I could investigate it.

there are companies which specialise in superchargers. go through your yellow pages and find one and given them a call and have a chat about your options. i'm sure they will let you know all that you have to do.

SC can't be too bad of an idea if mercedes chooses them over turbo's. also many american professional drag cars use superchargers because of their low-down torque and power.

would be great to see a SC skyline zoom past any gtst and do well against a gtr!

u gotta spend sum serious cash for that. The company I wastaling to was adelaide based, and they specialised in supercharging civics and the like, so I gave em a buzz... think they were working on a supra at the time, either doin a super/turbo twinny or a straight super, sumfin liek that, they were the ones that gave me quotes for manifold fabrication n stuff.

I got their email at home, I'll post it when i get back from work

    • Hmmm. that's a tough one. There's a lot of history bundled up in that lot. Perhaps instead we can create a new pinned thread, called "Legacy Pinned Threads" and provide links to the these ones that will be unpinned in there. And maybe put the names of the pinned threads that are linked inside in the tags so they can seen from the outside? Or something like? I mean, it's half a step back towards having a more complicated forum structure, without actually having it. But there's a reason that heirarchical architectures exist. They are logical, and if executed properly, make it easy to find something without having any upfront knowledge of where it would be , and without using a search function.
    • Can we unpin a bunch of dead / irrelevant threads from: https://www.sau.com.au/forums/forum/8-engines-forced-induction/ New players at home will scroll and think this forum is dead.
    • It's all about selling non-compliant emmisions stuff, and things like tuning stuff that makes your car have more emmisions, a very small percentage of modifications and tuning go into race cars, the vast majority of tuning and mods, like catless exhausts, or non-compliant cats, go into street cars with registration  Like a gun shop can only sell to someone with a gun licence, if they don't, they are fined and even jailed, and whilst a gun is totally different to a tune, or a catless exhaust, they are still illegal for a street car As for customers, it easy, they send a letter and tell them to show up for an inspection, like if someone says your car is to loud now, if they don't show up for the test, they can cancel rego, just like not paying a traffic fine This has been happening for years overseas in other countries  I'm in no way happy about it, but, I think there is definitely writing on the wall for modern cars with emissions standards, which will effect tuning shops, parts suppliers and end users And like other countries around the world, it is the government's that makes the rules and regulations for street cars with rego What would happen to a tuner or workshop if they were investigated about turning off stuff in a ECU IRT emmisions stuff like engine check lights for cats, or removing cats, or putting in a lower cell cat, this is apparently all illegal IAW modifications to registered cars, or, retuning the car so that with even stock emmision stuff still installed, but due to the tuning, or parts, like bigger cam shafts, it will now not pass the emmisions test Yes, I am going into a rabbit hole, but going off what other countries are doing IRT everything related to emmisions........cars, trucks, manufacturing, mining, modified vehicles are a easy target Meh, time will tell how it goes either way 
    • This^^^ 100%. Endless Male Attention. "buy a cool car, attract females". No reality is the opposite. "Buy a cool car, attract males".     
    • Just wanted to share the recent dyno results on my car. 20lbs of boost on pump gas. Pulled the fuse on the AWD so it was only rear wheels on the dyno. It made 484 hp at the wheels. I asked the tuner to see if we could do something so it breaks the 500hp level, but he said that we were maxxed out on pump gas. If i wanted to make more power, id have to go to E85.      8739a97a-9408-4eeb-b769-108ff1678736.mp4
