Anyone know a decent auto elec that is mobile in Vic?

Not necessarily an "after hours cash only" style job, need a professional that can un-f**k a clusterf**k.

You and Pat

[Leroy Peterson]

I dont know any mobile auto elecs, no. Will be taking pulsar to a motorsport wiring place to do stuff from scratch, seems like lots of auto elecs dont like f**king around with others peoples messes.

Also lol @ comparable deductions to other sparkies.
Claiming unnecessary performance mods for your car on tax is immoral. Like claiming dog food for security purposes.
Good luck to you, but youll probably get found out eventually and get reamed like Gregs R34 at Racepace.

[Kinkstaah]

But... but Racepace did literally nothing to my car..

perhaps that isn't the best example

[blah_blah]

I would say if Dez claims it the smart way the likelyhood of it being audited or found in an audit is about a 0.01% chance

[Birds]

Now stepped up to 0.02% since we're publically discussing how someone could defraud the tax refund system on a forum very few people visit

If I'm gonna do it, should probably get it done before eofy.

Other thing to consider is warranty... Walkinshaw / harrop etc offer warranty, at a cost, haven't really looked into how it affects the manufacturer warranty if at all... But my mate recommended dynomotive or dpm, sounds like they offer more and better quality for less than walkinshaw etc...

Does their warranty cover your engine or just their component failing? Be surprised if any engine modification offered liability insurance against total engine failure given so many indirect variables can cause it.

It's a dumb push rod v8 m8, she'll be right. 

 

[TiTAN]

Is a 6.2l with a centrifugal vlower not pretty much instant too though?

Except that centrifugal superchargers make linear boost as revs increase. Less revs you have the less boost you get.

[Kinkstaah]

Centrifugal chargers also have the tendency for an engine to not feel 'boosted' at all, a positive displacement charger you mostly feel down low, turbos give a big turbo kick we're all familar with

Centrifugal chargers just feel like a larger N/A engine, their power on a dyno is almost a completely straight 45 degree line. So you do get instant boost, but max boost is always at max engine RPM.

[UNR33L]

screw centrifugal chargers, if you're doing that may as well just go turbo, almost the same amount of stuffing around with plumbing etc. 

PD where it at, say goodbye to your tyres

 

[Kinkstaah]

After installing turbos, my next car is going to be a supercharger setup.
Heat management > ALL.

A RB with a 300KW centrifugal charger instead of a Turbo would probably drive like a similarily powerful V8 N/A (like a LS1-2)
Except way less problems with heat, lines, plumbing, etc.

If I was adding F/I to a car which didn't ordinarily have F/I (like a S2000?) a centrifugal charger suddenly becomes really very viable.
 

[TiTAN]

High power supercharged RB would be interesting but ultimately a gtx3071 bolted to the stock manifold would get you the same 300kw but a fatter midrange as you get full boost earlier.

[Leroy Peterson]

I think there's a handful of people who have done supercharged RB's.... I don't think any of them recommended it.

 

Hell even the supercharged SR20 people usually go turbo afterwards. Same with F20 Honda motors

[UNR33L]

Engines too small.. by the time you add a charger you're making it struggle even more, say hello to your RB15 (1.5L, that's the joke) 

Is there any point spending money on a EJ257? from my research looks like minimal gains (intake exhaust tune ~35whp?) Asking for... a friend.

Pls just stop

[Birds]

Changing the forced induction method on a vehicle that came factory with FI is very silly

Superchargers have a constant lag of their own that is just negated by the power gains when they start making a little boost. You'll notice it on a smaller engine and fuel economy will suffer even if not giving it stick

If you want that supercharger whine just do a gilmer drive or smash your air con compressor with a hammer until it whines

E85

Should be first stop for any decent FI power gains. Improve performance absolutely everywhere!

Oh hai

[TiTAN]

So that was a 3071. Wasn't sure if it was the 71 or 76
