Lets figure this out

Who was the the guy that raced a GSh through Canada? Lets see what he did, he had some dealings with Lexus. Maybe he could get some names.

LEXUS, you hear me!
Of course you can mod it, you can mod anything. I don't follow the modding scene on the GSh, I am surprise no one modded it yet. Maybe again is a Japan only thing, because I heard even the Prius, people have modded it to go fast with great success. Pretty stock Prius with the ECU modded for full power can do 0-60 in 6 seconds I heard...........that is crazy FAST for a semi stock Pruis.

Okay Mike... make it so i can disable my traction. Get 30% more power out the the EM.
Lets figure out how to lighten the car up a bit.

I don't have the specific details, one of my car buddy was just telling me. Google and search the Prius's forum is my suggestion to you.

It makes common sense, if you crank up the electrical side of the powertrain and completely ignore the gas saving benefit, I am sure you can gain a huge amount of power.

Oh I've looked, there is nothing much that they can do either. One guy turbo'd the car, but had lots of problems.

I would love to get more power from my GSh too.. but sadly it is pretty much impossible without a software change. The hybrid ecu monitors torque output to the tailshaft and I would bet money it won't put down more than you should be able to get with a stock setup. It would be nice if it would let you put down all 250 Kw at low speed though. The car is plenty fast but it could always be a little bit faster.

The real trick would be to figure out a way to put the AWD from the 350 on it!

Put AWD from the 600h... Aisin makes two versions of the HSD. 2wd and 4wd.

You would have to increase the battery size and output, the inverter output, reprog the entire system. Then beef up the cooling system.

Much easier to lighten up the car the HSD is in.

You could install a Tom's supercharger, but I don't think it's available anymore for the GS450h. NOS could be another option, although I don't know of anyone who has tried that.

I plugged my OBD II tool in to my car, and it shows ECU data, shows it revved to 6500 rpm on full load. Deceptive cause it doesnt sound like it.
And an interesting thing i found is that the ECU treats the hybrid as a turbo, when it uses hybrid+engine it shows boost on vacuum sensor, i thought that was a neat trick.
