Electric Supercharging

[nitroman]

I've noticed these electric superchargers for sale on the web for 300-400 dollars that claim to produce 2-3 psi boost at full throttle. has anybody used one and do they make any power. has anyone installed a "proper" blower on their Xr8?

This thread should clear it up for you

bwahaha i'd forgotten about that thread...
cheers for that casper....what a great laugh

[Casper]

yeah, I read it again too and had a good old chuckle

[nitroman]

Hmm... I'ts not so good as it seems is it? Why can't somebody make an electric blower that makes 6-8 psi like a proper belt driven one ? As they say life(and horsepower) wasn't meant to be easy....

because the power required to drive it would need a mini electric generator run by the exhaust or crank to power it.... which basically can be removed by running the blower directly off the exhaust (turbo) or crank (Supercharger)

because it'd draw so much current to be able to supply that kind of psi.... you'd have to upgrade the whole electrical charging system ( decent batteries, mammoth alternator) and it'd end up costing the same as a powerdyne supercharger kit

its far easier to take the drive off the crank like a propper blower does

Bugger.. I'll just have to keep playing with my cam timing. I installed a Ford Motorsport e303 cam in my Xr8 last week and it has killed the bottom end power, so I'm waiting for a Rollmaster timing chain/gear setup to show up so I can advance the cam a few degrees to get back some of what I lost without losing too much of the now great top end power. You get nothing for nothing eh.

[Mark351]

If you install a flux capacitor with the electric supercharger, ensuring the air-conditioning is hooked up to the intercooler, the benefits are amazing!

[nitroman]

I'll have to watch back to the futre again to get the details....

The good old flux capacitor , fixes everything !

I remember this...I got played!!! :

what are the specs on the cam? If its designed for top end power/torque, u will never get ur bottom end back to what it was before, not even an adjustable cam gear will fix that.

[nitroman]

The cam has 220' at 50" and 498" lift. Apparently it can be timed into 2 power ranges, 1800-4800 and 2500-5500. I installed it with the standard chain setup(being a tightarse on the day) and it kicks in at 2500 and pulls strong to the limiter,which of course has killed off the bottom end takeoff grunt so I'm hoping advancing the cam 4 degrees or so will bring it into the lower power range.

[LUXO_8]

is it auto or manual? ( im presuming its auto)
sounds like you need a hi stall torque converter

You only get what you pay for.

4 degrees is a bit, might start with a little less degrees. the cam doesnt sound too overly wild (or i have seen worse :newangel, so yer with an adjustable timing gear you should be able to bring the torque range a little down. In general its always a good idea to setup an aftermarket cam with adjustable vernier gears. have fun :eclipsee_

Engine running, flux capacitor... fluxing! LOL! :hihi:

I wouldn't mind fitting a high stall converter, trouble is the 100k cruising speed revs are about 1800-2000 rpm so i would have to fit a lower diff ratio (maybe 3;9) as well to make it work. By the way, are the au irs diff crownweel and pinion the same as any old borg warner, ie can I get a diff from the wrecker and use the guts in my diff?

[NeishaXR8_347]

dial the cam in properly by going by the specs. usually the easiest is the lifter rise on the overlap on the inlet valve.

[S3SR]

isnt that exactly what a hi-clone does?

i thought about this also and found to make the fan stand alone or run from the engine it would draw about the same amount of power it produces..most likely even reducing the power

[REDAUXR6II]

aaaaaaaaaahahhahahhaha what a load of bollocks, you want a super charger then bloody buy one.....not one of these modified hair dryers.

going from the stock 3.45 ratio diff to a 3.9 ratio would increase highway revs not decrease them....

a stall wont alter the highway cruising speeds ( well it shouldnt ) it will just allow the vehicles "take up" point to change from the stock 1700 odd rpm to the higher rpm..... your car will bw in its powerband much faster, increasing acceleration...



i'd say your cam picks up at 2500 or there abouts and you're noticing the sluggish low rpm's due to too small a stall speed... a 2500 - 2800 stally would just about completley change the car

[nitroman]

I know what you mean, It's like slipping the clutch in a manual to a higher rev. I'm just worried about the converter "slipping" while Im at cruising speed when It's supposed to be engaged which might stuff the converter if used as such for a prolonged period.
I've heard that there are converters and there are converters that actually work well. I believe a good converter will lock at a light throttle and slip when you really hit the gas. Who sells the good ones?
And yeah I realise a higher numerical diff (eg 3;9 vs 3;45 ) will increase highway revs. A higher number is called a lower diff ratio for some reason.
I'm gunna loosen my rockers a shim and advance my cam timing this weekend and see how that goes, then I'll have to consider a converter if i don't get the pickup I want.

god that was a funny thread

[XR6-VCT-2000]

lol , but but but E=Mc squared , so it must work ...lmao ...

I haven't even bother reading the previous thread again , but im gathering it's the thread from a few months back where the dude tryed to cover his butt for ages, insisting that the electric supercharger was worth while ! , but was eventually proved wrong , then he tried to say he was really stooging everyone, seeing how many people he could suck in .. imo eventually i think he was the stooge ! ...lmao ,

[TheSneakiness]

Sorry about this, but I was lurking through eBay and found they've taken it to the next step, by adding a pod filter and a "blow-off valve"...

lol i just read that gen 2 one and a guy has a 1.4l civic and he said with this activated he is basically all over the road, pretty hard to believe hehe.

I've seen the DELOREAN at the Blue power work shop!
Was it there when you were there Mark?
