Yes that is at the wheels.
Perhaps Aaron will post up a pic of the graph.
It is the Black 20B Kombi from Warwick last year,
that only(!) had 570 last year and went 6.8 then.
Some may not like that it is a non-VW engine,
but if you know Aaron you will realised he is a hard-core Volksy Dude, and all round good guy,
which makes it just fine with me.

Well done again Aaron - man, on pump fuel too! It is surprising how sedate it still sounded today around idle and low revs. That would be a scary ride when you open it right up!

and i took that beast (thomas) for a drive the other day (and i liked it). when i gave it a little and changed from 2nd to 3rd it made me smile.🙂. You can feel the power and it feels strong and safe on the road. Good work aaron
p.s the crazy bugger parked the kombi this arvo and started to work on his brothers kombi, he never stops.

yes i was at aaron this arvo suppling a few fittings to make up a air cleaner to cover the 6inch front cover on the new turbo until the new air cleaner arrives. From 80hp at 80km/h to 715hp at 140km/h it really ramps up fast. Great work mate, let me know how you go with the dyno tomorrow so we can arrange what we are doing sunday

Hi its Aaron,
Sorry guys i took so long, got side tracked with another vw.
I would like to thank all vw folk who support me, and help get this master pice of mine so far.
I'll post all spec's soon, no black magic here, just self taught and r&d.
Have to go back to the dyno to reset the fuel presure as the guage was reading incorrect (90psi instead of 45) bugger. oh well.🙂
4am start at work tomorrow so talk soon.

the car ran 6.8sec at 102mph last year with 570hp atw so this year it should run into the mid to low 6ses mark so long as the gearbox will stand up and get the power to the ground. Aaron has rebuilt that gearbox 6 times while it was making 570hp so he could be in for some more long nights rebuilding trannys..

Back from the dyno this arvo and it made 715hp 3 times, 714hp 3times 15psi (must be the wether) and about 710about 6.
Also tryed it with the air cleaner on, 701hp
Got the turbo comming on faster with more timing
And power is still 655hp at 9500rpm
All is safe 715 again 15.8psi 11.5 A/F 6'adv timing 98 BP on tap, yumm yumm.

The wire came off the toggle switch when i was jinnin around with the dash. So ill test it on around 18psi in 2nd and 3rd at the track.
Should be fun!!!
I didn't order albins cv cages, insted i bought 4 commodore cv's and 2 moer shafts for $110 all up. should be enough spares, I hope! 😂

0.787---2.439---82.27----8.984 wheels up then spin in 1st, missed 2nd, race was against Bec (I lost)
0.779---1.606---98.25----7.324 wheel spin but still good 60ft, long time to engage 2nd
Sunday racing (dialed in 7.125)
1.041---1.796---90.73----9.375 Trials, wheel spin, missed 2nd, with lower tyre pressure (20psi)
0.613---2.229---99.11----8.209 (18psi t/press) bogged needed more revs 6500rpm
0.629---2.053----92.40----8.260 bogged again,
The last run was a bye, lost time slip (16psi t/press) lots of revs 8500, i let the clutch out to quick, once again more tyre smoke.
At this stag the bus will go back to the dyno to set a lower boost in 1st (new gate spring) and maybe e-boost controler for more in 2nd and 3rd.
I'll also look at a valve for the clutch release and staging on a set limiter.
Just to much power for this size tyre on the line. 235 x 65 x 15 radial tyre. I've found 500hp is just right as in 2008, so will aim for that.

Thanks Guys and gals, and Troy for the pic's.
I've been a little busy lately in the shed. It was time to fit bigger tyres, this ment moving the spring plates inboard 75mm and an entirely new air bag
arrangement inboard of the chassie, modifying the trailing arms, brake lines, thottle cable, radiator pipes, barrel cooler pipes, 1 fuel pump, filter and lines.
Oh the oil cooler lines and all the wiring that you forget thats under there.
So much work just for 50mm more tyre each side. The tyres are Micky Thompson ET Street radials 275x50x15, which measure 295mm o/a not like my old
235x60x15 that measure 235mm o/all.
I didn't think how good it would look with such big rubber, i was thinking more traction, more traction.
This brings wheelie bars to to mind. So i borrowed next doors to see where i could mount them.
They are just sitting there in the photo.
The exhaust has an electric butterfly mounted near the rear of the race pipe,(4''). The standard exhaust no longer goes forward around the transmission
and back. Now is comes straight off the race pipe near the turbo using 3'', under the scatter shield (bellhousing) 90' in to a 20''x 11''x 6'' tri pass muffler
exit through 4'' tip. 800mm of pipe in total.
This means i have 2x 4'' exits and 1x 3'' wastgate exit. The ability to have full power without excessive back presure and only have to change
sparkplugs on race days.
Now i'm working on a new shifting system.
While Troy is moving house his lathe is being stored (used) in my shed. First job done, machine alternator pully central, second job?????

Well Bec and I were ment to be at a car show today for a sunday cruze and some dyno fun but,
I went out last night to check every thing was right. While under full throttle 3rd gear the boost went sky high!!!!! 20+psi
So i took some data the next run and wound the air reg down to 0 = 10pound (spring presure only).
Straight up again, and i couldn't back off quick enough, then it did two big back fires and stalled.
The problem with such a big turbo is when is comes on it does so, MEGA quick. This high boost causes high heat on these
tiny seals and they weaken, causing then to bend or break.
The fault was a rip in the wast gate, which controls turbo presure.

so rotor housings suffer any damage?? Rotors ok ? Or just some new seals etc etc??
20bkombi ·
Sad to have to open it up. Looking at the wear it was not even 1/4 of its life.
This would be the cleanst engine i have pulled down yet.Every thing is just as it was 3 years ago. I will replace the corner and side seals with after market ones, as there were only
mazda (i hate that word!!) items at the time of the build.
This means i will have (South Coast Rotary) SCR 3yr old apexes, new SCR side and corner seals. All with new factory springs.
All up $450

Yep all factory 20b parts, only the dowells apex seals, and balancing of the rotating assembly.
But, all the springs and inner, outer oil control rings are from 5 different rotary engins for different reasons.
This is the twin plate clutch, will try and grind it on the lath.

Thanks. The rebuild Won't be for a while, I have other work to get out the way first.

The gear box will be getting pulled down this weekend to try some syncro
mods for better shifting.

Still waiting on parts. I did some more porting to
the exhausts and made a bridge in the primary
intakes (idling port)
Dave took a skim off the porsche diff housing
to make it square again. I'll build the box this w/end.
Dave alsow took about 1mm off the exhaust manifold,
now it will seal!! And come on boost quicker.

Primary port
New primary and secondary ports
With a bridge port you have to take some off the matching housing
Standard and extra large exhaust ports

Ah, rotors.....been a while since I've seen bridge ports.

Will we see 800hp ?? Not that figures mean anything LOL
20bkombi ·
I havn't built a 20b with my style of bridge port on both primary and secondary. The exhaust port is the bigggest that I've done in that position.
I'm not really chasing any figures at this stage as this will be free power, so any increase is a plus with out adding more heat from the turbo.
The first dyno will be at 16psi to see the changes, then will be set around 18-19psi staying with 98 octane. 800hp would be nice, as long as it's usable.
One day i will use the engine to its potential. With methonal, good ignition and twice the boost!!!
But for now the box is once again way over it's limit.
I know its not vw powerd, so thanks for following the thred. Any questions on rotary engines, always happy to share.
I think they are over looked because of there sound and failure in the eirly stages of production (30years ago)
as aposed to piston engines 80+yrs,with multiple companies refining.
I'll post some pic's as i put it to gether so you get an idea of how simple they are.

This is the first time i'm using the limiter and clutch control, so it feels like i'm starting drag racing all over again.

I think Aaron smoked a clutch.
20bkombi ·
Sorry about that, I've deleted them,,,, stupid wireless net.
Only one run at the drags today.
Safely home with no chutch, just a bit tricky when starting and idleing in 1st is 22kph (poor starter motor)
So, I think I had a good out come, the new rear suspension,(air bag) with the added help of torsion bars, larger tyres, new gear shifter, wheelie bars, clutch management, and using 2 step/antylag.
With the staging limiter set at 6500 and 10psi I left the line with a 1.73 60ft but the clutch kept slipping, then rpm was to high for 2nd. finally found 2nd with more slip.
1/8 8.16 @86mph
1/4 13.21@79.67 mph, never got into 3rd.
With new pucks on the cluth I think I will get the 60ft down better than my pb of 1.52. I'll change the clutch proportional valve i'm happy with wheeli bar hight, air bag pressures, 25psi in the tyres and 2 step 6500rpm start and 9000 shift.
Until next time.

I just watched the vid that bec took and showed me that the wheelie bars were used all through out 1st gear.
Looking back at some old notes (2009) a 1.7 60ft time usually means around 1ft wheel stand.
Got some data from my logger which told me that at using the anty lag set at 6500 it actually climbed to 7200 when as boost increased.
As i lifted the clutch quick as possible the micro switch was set to close to the floor, trigering the ecu to switch to normal program to eirly causing the engine to goto full rpm seeing 10030rpm (limiter) for .41sec's before the clutch started to grab all because of the clutch fluid transfer through the proportioning valve to the hyd throw out bearing.
So all i have to do is moove the micro switch about 5mm.
Alsow saw that there was slip for about 2/3 1st, so will give the clutch fluid less restriction.
This may all change with a new clutch.🤪
The clutch was 3 1/2 years old and about 60 passes at the strip with all my normal road use (including hill starts) and my street testing.
I'm going to look around for different compound pucks which can handle more heat and see if technology can helpout. If theres nothing much different i'm happy to go back to what i had.

Looking at that pic at ground level, rather then the grand stand, the rear suspension could do with a bit more stiffing up. Thats the info the driver can't see.
Was also looking at putting a sensor on the input shaft to log, so I can tell the exact engine rpm to g/box rpm, on launch and throughout. Would be good to see the difference when theres more heat (back to back runs)ect.
Alsow have travel sensors for the suspension, if needed later.

Your 'black book' of data will rival that of the Muffin Man's very shortly! You will need to develop a spreadsheet to record and analyse all the data from the multitude of sensors you will have in place. Can't wait to see it with a bit more clutch fine tuning.

Hi Aaron,
Mate your Bus is the ultimate wolf in sheeps clothing. Awesome job.
Any chance you could describe how you keep that beast cool.
I've got a 74 Bay with a V6 Chev and I'm running A VL Turbo radiator mounted under the belly with twin fans and an electric pump.
It's fine around town, but gets a hot on the highway.
That 20b must be pumping out some serious heat. Any chance you could share your secrets?

As usual the porsche box is striped with alot of new parts going in. All main bearings, 2nd gear dog teeth, 1st/2nd slider and hub, 2nd gear synchro, another crown wheel and pinion, and redline 'heavy' shockproof oil.
The new tilton triple plate clutch is in and working great.
The whole fuel system is now changed with aeromotive mechanical fuel pump (belt driven), EFI reg, billet 100 micron filter, and 6x 1600cc injectors.
Now i can run E85 pump fuel.
Alsow I've made a 6 point cage, mounted other seats, and 2 sets of 4 point harnesses.
Changed the alternator bracket and ice box for the intercooler.
New braided brake lines for the front, (old ones were shagged), new rear brake pads and rotors.
I think thats it at the moment!!

Aaron with using the redline shock proof oil I have quite a few boys involved in circuit racing cars from the Toyota scene who used to use this and thought it was great. But after a period of time it begins to glaze the synchros up and causes shifting issues. One of the guys I know who swore by it used for about 6 months doing track days twice a month then noticed he started having issues with gear changes and thought it was the clutch on it's way out. New clutch but nothing changed. So pulled box out and sent it to a gearbox specialist who stripped it and showed him all the synchroes were glazed up with some form of coating which was the cause of the problem as everything else was good.(gears, bearings etc etc). New synchroes and no shockproof redline but switched to royal purple and never had a drama since.
He let a few other guys I know about it and there was 2 other cars that had similiar issues. Both did the same thing with a rebuild and switched oil and no more issues. Now whether or not this is just related to Toyota boxes or not I dunno but thought I'd let you know before putting it in and then having to do more repairs later on cause I know you just love pulling this thing apart!! Bet you could just about do it with your eyes closed!! LOL

Cage looks good mate!! Are you thinking of adding some bracing in the rear of the car as well? Torsion housing to chassis rails through body and engine bay perhaps??
By seeing the pics of my cousins dual cab after his big accident there seems to be somewhat of a weaker point in the chassis around the front of the torsion housing as the chassis kinked at that point in a frontal impact accident. Mind you he hit a VE commodore at 60km'hr with little to no braking as they did and illegal turn in front of him.....

Thanks Brendon, good to know that i should look for synchro glaze when i pull it down again,.. thats right!! I am planning on pulling it down again
after Warwick just to check every thing, these are the things one has to do on a regular basis when putting more power through a transmission than is designed for.
Even with a possible glazing problem, I will still use this oil just to try and save the crownwheel and pinion ($2200). Synchros are only $36 delivered.
Thanks for the heads up, ill keep you informed on the out come.
The rear stays are mounted to the torsion tubes about 50mm in from the chassis rails, The main reason for the cage is for my safty up front, And to keep
it safer mostly on the street. It is getting blue plated this week end, i sent through photos as i went. The pipe is 4.2mm thick, which is over andra specs.
Thanks Andrew, your right the tiles are finished😂, But as you know, one door closes another opens😢

Nearly 1 year since I've posted anything on the bus so this is what's happened in that time.
After breaking the input shaft at Warwick last year I pulled down the porsche box again to put the new shaft in which comes with 1st and 2nd gear $$$$. While it was apart I replaced the pinion retainer studs, grade 8.8( 8mm), with 10mm 12.9 grade and longer as well. The old studs had stretched and left the nuts loose.
And I now have a $1290 clutch alingnment tool😂

After using E85 ( 76%) fron the local caltex, this is what can happen to the fuel after sitting for 4 months.
I then cleaned the whole fuel system out, got the injectors cleaned and flowed. Also I saw the fuel tank had surface rust in it. I put some old fuel in it with some big washers and sloshed it around replacing the fuel until it came out clean. Then used a tank liner to seal it.
Red Kote.
While the lower half of the intake manifold was off I ported it to suit the engine, about 3mm to come off each port.

I noticed the rear hub nut was a bit loose because of the huge offset rims (63) caused the hub to ware out. The problem is that there is no support on the inner, where the spline stops, so I made a brass bush that fits firm.

I'll tune it more at the track.
As we were heading in the right direction a tyre let go at 8500 rpm 4th gear, THATS 303KPH!!!! F... N bang!!😂😂
You can see the tread at the back of the dyno room where it landed.
Lucky we weren't hurt.
And some quater damage, it was worse than it looks. But I got it looking ok.
The bus is now ready to race once again 🤪

Good to see Scott isnt the only one ripping tyres to bits on the dyno LOL
Somehow I think you might be making just a tiny bit more power thatn he did!!
What sort of numbers did you end up with?
