Welcome to the forum. Look forward to seeing your system and results

Hamilton NZ which is at 40m above sea level.

There is some voltage leeway on the Max. 4 ............... something I've discovered :LOL:

When I specd. everything I was only aiming for an extra 30-40whp and anticipating around 250A. But you know ..... 'moar powa baby' kicked in and It's actually at 360A and pretty much everything is on the small side. The batteries themselves are only 20Ah LTOs as I wanted to keep the weight down...

Put Bluey on the dyno today . Was hoping to break 300whp but didn't quite get there. peak power of 282whp with impressive (for a rotary) midrange torque of 204lb/ft. Note to boost decline 6.5 down to 4psi at peak which was a little disappointing. Black trace on dyno was same car N/A so an...

It struck me watching that video that are lot of guys are missing another huge benefit in running the P2 SC. It barely restricts any flow to the engine at airflows below approx. 190g/s (25lbs/min). I have proven this on my engine, a13B rotary which consumes approx. same amount of air as a 3.3L...

Look into the Torque Amp system from Sweden.

Interesting conversation. Was talking to a friend over the weekend who races his rx8 in our local series. He had a faulty isolating switch recently and it resulted in almost every electrical component on the car being fried - who would have thought! wkerstens, no I don't have the sensor cable...

Don't have a cat. This car has seen multiple track sessions pre eSC also and I've never noticed the smell before.

Went for a really good long drive Sunday which included about 1/2 hour of twisties where I got a chance to test the system. Some observations : Battery : got down as far as 44v and found it still performed well without noticeable engine power drop. Temp got up to 40C which is quite acceptable...

That's one of the ways that you don't use it ....lol Dynos use a ramp rate which tries to match what actually happens on the road but is never exactly the same. So no - you can't do that.

I use Mazdaedit as a tuning tool and that has 'virtual dyno' as part of its software. I've also had numerous RX8s on a real dyno and have learned how to get the virtual dyno results within 5% of that. VD is fraught with traps for the unwary and you can easily get ridiculous results so It pays to...

Yes ...WHP . Add another 50 or so for crank.

Have not hooked a gauge up yet but I suspect it's around 5psi lower down and 4psi up top. Is it maxed? .......... I dunno. The more I experiment the more It hits home that the ratings for all this componentry is based on continuous current so can be exceeded by a wide margin for short bursts. I...

New 25T pulley installed and tested. Results below are best I've seen so far. Saw as much as 346A at 44V on the BMS Getting batteries warm definitely has a positive effect on power output. Even with LTOs, which supposedly work down to very low temps.

Depends on your goals ......... 22 gave me 4psi in midrange and 3psi up top at 250A but I want to max out at around 300A so went with a 25T. Should give me another 1 psi.

The shaft rotated against the grubscrew and bent it over in the thread

Have just found a weakness with the drive pulley on this new motor setup. The M5 grubscrews holding the toothed pulley are insufficient for the job. The one that tightens onto the flat part of the motor shaft basically twisted in it's thread and allowed the shaft to rotate past it. My plan is to...

I have much the same components as you and have just found a weakness. The M5 grubscrews holding the toothed pulley are insufficient for the job. The one that tightens onto the flat part of the motor shaft basically twisted in it's thread and allowed the shaft to rotate past it. My plan is to...

Not knowing much about electrics myself, the choice for me was simple. Follow someone (AKA alexltdlx) who has had success and fine tune from there.
