Chaps

looks like these have finally come of age

I think he's doing himself a disservice with that pressure map, as the dyno results would seem to offer a lot more than this

there was an article in MTZ back in December about a similar device that also offered a similar level of promise but wasn't commercially available at the time

this phantom item ( unfortunate choice of name I'd say) looks like its delvering some tangible results

this looks to be a proper bit of kit unlike the Ebay cr@p thats touted

also I'd agree that 1.5 psi of boost at 6K engine rpm isn't much but 5 psi at 2K rpm is a reasonable amount and this is reflected in the dyno results

as its takes about 30 minutes to fit to a car I feel its worth investigating further

there's another one here:

Thats a valid point but this thing can be fitted in 20 minutes with basic tools

you can't say that of a turbo conversion

plus it may be $1600 but thats still $2000 cheaper than a full fat turbo conversion

I think you're missing the point

the power to drive the charger comes from an additional battery which is charged up when the unit is not working, so you're not robbing
Peter to pay Paul here




this a power at the wheels dyno plot showing the before and after

Now now

the extra battery is charged from the alternator when the unit isn't running
so when you're on full throttle the charger is drawing power from the battery, when you're off full throttle the battery is being topped back up

So you're not charging the supplementary battery and costing power when you're using the boost - hence the comments about it being like re-fillable nitrous

it doesn't involve the main vehicle battery at any point

I don't think it's meant to improve engine efficiency or to be a too good to be true energy-for-nothing job - it's just a supercharger which defers the parasitic losses until the engine is not required to produce maximum output.

thank you

its not a perpetual motion machine , nor did I claim it as one

but it is a very easily installed superchrager

Funny



So a measured gain on a dyno isn't enough to convince some people that this is worth pursuing or is a valid product?

What more proof would you like exactly?
