As a workaround for the two stage launches, I have hard wired the Suprastick into manualised mode, Dan has reset some of the pins so I have mended it in 'old money', it will remain Flappy-Paddles only for now. It had to be tested as well, didn't it! I doubted my wisdom of recording the first test, filming with my left hand, missile-guidance, Warp-changing and after-burner control with my right. It boosted straight up to 10psi and tried to step out, caught that, cut timing for traction and caught a much faster change, balanced out the last little wiggle from the wisping rear whilst watching the AFR read a nice safe 12 and guiding this mystery surprise missile down a road that I'm sure was longer than that? Another 2psi has made an unbelievable difference and changing gear before the plugs blow out, keeps the power coming on like a Bullet Train. The Hybrid box gave perfect WOT changes with the new timing-cut feature, it's like going up a Warp factor. This will be the last of the hand held production videos, I will get myself a camera lick and stick-on thingy. Come for a ride in my Rocket Ship. [video=youtube_share;TFb-tvM7g88] The best bit of that clip is regaining traction in first by manually cutting the timing and slipping the torque-converter. When it broke loose, I held the throttle steady and pressed then held the up-change button, which via the AEM cuts the ignition timing back to 6 degrees BTDC and via Suprastick unlocks the torque-converter, traction regained, I then released the button when time came to change into second. You can't see my finger move, but it shows on the waving clocks and in among the noises. Home made Manualised Launch Traction Control in action.

Here's a pic of the belt I smoked yesterday. Replaced it with a shorter belt that only goes on by a gnats nadger and took a clip of the wonk. [video=youtube_share;vu-fAJ8VdiQ]

I have been out practising my Wolf-Whistles, I didn't manage to do a good one for the clip, I think I may have reached the limit of my multi-tasking. Driving safely through town, feathering the bypass valve with my right foot, trying not to crack up laughing and filming it too was a tad too far, but I had a go.

Today 'my garage' achieves escape velocity and enters the 12k club. Thank you for your curiosities.

My Saturn 4-speed Flappy-Paddle Hybrid clinches the biscuit. :p
-
I had a couple of emails back and forth with BMW Tech Dept, the box is not as strong, 700 ftlb tops. I don't have any nuts&bolts fit info.

From the album: The Coolest Supra ..... in the World :)
-
I'm trying to resist, but I have this urge to go and burn a tank of fuel and smoke another belt.
-
I'm looking forwards to seeing it out on anything soontime.

Here's the other one, taken going up the village strip on my way to pick up my Dad who starred in the first clip. This is a cleaner launch without a brake testing scene or the place camera on lap and get around a 90 degree left whilst semi-paralysed with laughter trick. This about sum's it up.
-
Not sure how this wizardry functions, but maybe some whizz could work it out with 3.769 ratio? Whatever it presently is, could might be is irrelevant, it's that flat torque curve with loads of space under the left of a very low rev graph. The acceleration is reliably and relentlessly linear and combined creates an awesomely different experience. Every start up is an occasion and every dab of my big toe a great pleasure.
-
I write Noz a bed-time story and now he pm's for more video's. I only have 2 more, both just a different flavour of the other two, this one is a slightly longer clip of the smoker.

I'm itching to get it sorted, I want to run it at Jap Show Finale, 29th 30th Sept but Bob's not back till 22nd. My pleasures today have toasted the belt and I must now use it least and lightest until then, I only have two more that size, arrived today from TX. Then back for another go at mapping before the end of the last week, it's getting a bit "Cinderella" for my liking but I will give it my best shot under the prevailing circumstances.

Thank you for the congratulations, I could almost forgive you all for not remembering my birthday for the last 2 years. I'm really pleased the Project has progressed to this stage. I've been on several little errands today and have never had so much fun from a car before, if Toyota had made one of these they would have sold millions. At low speeds the car trundles along quietly, calmly and as sweet as a nut and at very light throttle around town, by feathering the throttle to catch between -18psi to -15psi vacuum, I probably shouldn't admit it but have found that I can actually give a wolf whistle with the supercharger bypass valve. The power is available instantly, any time any place any gear any revs, it goes from nowhere to gone where so quickly, I can hear the click of the bypass-valve, just before the one in my neck. The beans are not to be stomped on, more like, pressing a clitoris with your big toe. I haven't yet managed to do this without breaking down with laughter after the launch, I've taken a few friends and family out for short blasts, there's no need for any of that double-braking high-stall torque-converter and launch control malarkey, just press the go pedal on the right and you're gone. Until I can get access to the workshop, I can't evict any of the Gremlins. Currently, the belt is slipping @ 8psi @ 4,500 and the transmission set to change gear @ 6,550rpm @ WOT, yet the plugs start blowing out over 6k and the pulley is geared for 15 psi and the manualised gear-chance funtion is not working so running in auto-mode only. This makes for the most amazing and totally hilarious two-stage launch to 80mph and even in this handicapped wounded condition it's an awesome experience, I can't even imagine what it will go like when it's working properly. Whether from start or roll, make sure the car is aiming exactly at the point of exit of view and remember not to blink, because by that time you are where you were looking at, it's like being in a catapult launched two stage rocket. It's an amazing experience, exclamations of that's AWSOME followed by spontaneous laughter, I don't know why it's so funny, but even thinking about it keeps me laughing. There was a new set of traffic bollards under deployment, filtering the dual carriageway into left lane which was chocker block, me on right give big sad pleading eyes contact to one of my last chances to get over if he'd let me in please. Man on left, F.B. with a drive-through mega beaker of something in his right hand and elbow stuck out of the window, gives me the "no-chance buster" eyebrows. My last option was to get past, I didn't count how many cars for the last doable gap ahead before certain doom. click-POW and before F.B's. eyebrows had even retracted, a Screaming Banshee erupted under his right arm-pit and launched out of view leaving three perfectly whisping smoke trails, two from the tyres and anher from the screaming-superchargers slipping-belt of fire poking out through the hole in the bonnet. Holding steady guide of my Supra missile, I managed a micro-glance in the mirror and his beaker elbow was waving a fist out of the window. I'll be glad when I've got the lid on it and in grey primer because it's attracting too much attention for my liking, just driving across town gets kids on the Street cheering and leaping about, even had folks rush up to get a closer look at what's in Mad Max's hole when I stop at the lights. Maybe it's the Bernard Cribbins Fan Club? On it's first day of limp existence, I've had my first ever Supra assisted 'offers', two in an hour even, look's like I broke my Supra Duck in style Noz. I wish I'd a fiver for every time I've heard the word "AWSOME" today. It just is.

I'm not an electrowhizz, but in old money, count the number of divots on the drive-shaft and multiply it by two.
-
From "N/A Van" to "Virtually Epic Supra". That's one small step for N/A, a giant leap for Supra-kind.
-
Presently @ 8psi but after the last of the Gremlins are chased out the target is 18psi.
-
That list, along with the bodywork and final 'normal' things to do, will keep me tinkering and you looking for a while yet. Egg in here in, I like that.

Hello Chris, long time no post. I'm not sure of the numbers, I wasn't taking much notice because I was too busy tinkering with 'things' to keep Dan pressing buttons undistracted. It's only pure chance I took the pic at all. I don't care what the numbers are, IT'S WORKING. Whatever they are, they will be larger after I have tinkered out the Gremlins.
-
I have another Hybrid made up and another couple of boxes ready to build another, but this one seems happy enough. Presently running at 8psi, when I get the boost up to 18psi we'll see what it can really take.
-
That will give my home-made gearbox a good testing.
-
You can see on the graph where the belt slips at 4,500rpm, the torque stops climbing and the linear bhp line is bogged, when it's sorted that bhp line will continue linear up to 6k+.
-
That's at 8psi, wonder what it'll be when I get it up to the target 18psi.
