Just thought I'd start a quick thread giving you all an update on the racing in Australia over the weekend.

The Jamboree is the biggest 4 Cylinder and Rotary drag meeting of the year.

Everyone was expecting the big hitters to come out and play, unfortunately this also meant a very large number of breakages and oildowns. I think partly due to everyone pushing pretty hard, and also the surface being relatively sticky. It was a pretty hot day (85 F) and there was a large crowd in attendance from all over Australia enjoying the sunshine (probably 15,000+)

The 20B rail of Corey Armstrong had a few dramas on it's pass but was quickest on the day, running a 7.7.

The Pac Performance RX-3 sedan came out and ran a very strong 7.88 at an amazing 179mph! Impressive considering the aerodynamics of the car! This RX-3 does not have a "smooth" fibreglass front like a lot of the US cars that I saw, so we can expect big things from their MX-6 which is currently in the build.

Archie from Mazfix ran a strong first pass in his 20B powered 3rd Gen RX-7. It carried the front wheels a long way on the launch, but then the chute failed to deploy and then the brakes locked and the car touched the armco in the deepend after crossing the line with a low 8 second pass

Rotormaster came out for last pass of the night and ran through for a 7.86 @ 171 for a new PB (and quickest "doorslammer" of the night)

Bill Nabham from Mazsport came out and set a PB with an 8.25 @ 160 odd mph in his "Series 8" style RX-7.

Expect a full update with photos (and video) on www.fullboost.com.au soon


PS. (Oh and I ran a PB of 10.2 @ 133 in my little first gen RX-7) (And didn't even break a stock Turbo II gearbox in the process!)

AJC13B

The Pac RX3 ran a fairly slow 60ft of 1.35. The car has run a 1.21 60ft and run 4.8 to half track at 150mph. On the 7.8 it went 5.0 to half track @ 145mph. This car will go alot quicker! The box is also a manual shift, no airshift.

Its also essential to note that this is a customers car, their own full chassis carbon fibre MX6 is yet to race

Angus ,glad to hear you guy's had a great time. Man congrats on that 10.2 on your sweet first gen. Hmm Steve did you go? that would be a nice Match race 2 street first gen's running similiar times and going for the fastest street Rx7 title.

Damm good time from the PAC customer car,

this is what she looks like

Judge Ito

that picture is so sweet you just made my day. God bless Mazda.... Man that rx3 looks lovely..

I saw that car this morning - it wasn't a touch - the shock tower has moved over for starters! They're still deciding what to do with it.

BTW Congrats Angus. Are you going for 9's on a t2 box?

-pete

madaz07

hey ajc13b what happend to your car did you break your gearbox

AJC13B

Yeah I raced, but the 2nd hand import box we stuffed in the car wasn't up to the gear shifts I tried to dish out. On my first pass I snapped the shifter and couldn't hit any gears, and the 2nd pass I couldn't hit any gears either.

Shifting normal is fine, but hard shifts its not into, so the box will get redone and we see what happens from there

Ito - Whats the quickest 1st gen on your side of the planet? What are Angus and I up against here??

Judge Ito

Steve, you and Angus are right on point. We have a 12A first gen. running 10.10 a 1979 13B turbo on a holley carburador with a powerglide automatic tranny running 9.90, a 1985 Gsl-Se running 10.00 and one more running 10.10..all this cars are street legal. Complete interior, sound system and alot of boost

AJC13B

9.90??? Holy ****!!

We got some catching to do Angus! lol!!

Judge Ito

Steve that first gen that ran 9.90 was on a automatic tranny, the car had a sloppy 60' very lazy coming out the hole but it still mustard that 9.90 very impressive.

AJC13B

Got any timeslip data? Half track etc? What MPH?

Judge Ito

No time slip data. It was back a couple of years ago in one of the many pan american nationals. I could try to find some info. on the owner of the car..

madaz07

yeah ive got new box for my s4 13bt my syncros are shagged also noisy bearings. but inm still deciding what clutch to get??

AJC13B

Just a one tone clutch and pressure plate would be fine for under 300rwhp...

david67

hey A777 you forgot to mention the unforgettable hook up by the Mazfix Cortina with the 13b (i think)

madaz07

i was going to get a 2800lb billet press plate with a bonded and riveted clutch plate how does that sound. in the near future im putting a fmic in dont know how much hp that will give me, but the clutch should be alright??

REVHED

Here's the vid And yes it's a 13B turbo Cortina. Probably the most incredible launch I've ever seen... a must see.

hondah8er

A777 do you have any pics of your car? I would love to see them and a little more information on your car.

a777

Thanks Judge Ito

AJC13B and I were trying to line up for a match race but it was not to be

Steve didn't have as good a night as me, but I was a very happy guy after the 10.2

a777

I've still got a bit up my sleeve!

a777

I was making an understatement Pete I assumed that after a low 8 @ 160mph one could assume that a touch would be a bit more than a touch

Thanks for the kind words though, and yes I may try for a 9 on a t2 box Although Willowbank is closed for 6 weeks or so while they upgrade the walls and run-off area.

a777

I should have my website done in a couple of weeks but basic run down is

1985 Mazda RX-7 (Series III)

Engine: 13B turbo (Series V - 1990 - built in garage at home)
Gearbox: Turbo II Gearbox (Series V)
Turbo: Garret GTBB turbo
MoTeC ECU
26x8.5" slicks

10.2 @ 133mph
Best 60' of 1.36

93 R1

That think is ******* sweet. I'll have one someday. I'll never sell my 3rd gen though.
