17 When I bought it. 30 now..

How on God's fertile green earth does one use 173 whp to run a 12.2 on the quarter mile?

Add lightness and set the car up properly.

Few small updates -

Picked up a billet Garret GTX2971R

Fitted up mostly

But I may have a new distraction

Alright it's been a while since I last updated. First up I got it tuned and it currently has 173 extremely linear hp at the wheels. Overlaying it against my 280 hp graph is disappointing. Polished the inlet manifold and added some color. If it's slow at least it can look pretty.

Anyway, took it out to QR for a shakedown. Initial feel and throttle response is great. Lost the bolt which stops the throttle body over extending so that ended the day prematurely.

Next up was Jamboree. I wanted to run the gas but couldnt justify the cost of a new clutch just to run it for 1 day. Threw some old slicks on and straightened the wheels. Ran consistant 12.3's all day with a 12.2 @ 108mph at the end of the day All Motor. Very happy with that considering the hp. The 6speed gearbox feels amazing compared to the starlet box. 4th gear burnouts along with 8500rpm limiter and dump the clutch all day long.

I then went back to QR with my issues solved. Also trialled a new light weight splitter. Car is feeling very strong and balanced. Ran consistently all day without backing off. A little bit of understeer in the low speed corners though. Ended up cracking the 300mm rotors on both sides so went home early.

After that I headed to lakeside where momentum is rewarded much more than outright hp. Took some getting used to as I havnt been back there in 5 years. Got stuck in traffic most of the day. Just when I got a clear run, I hit some debris entering Hungry and went wide off the track. Splitter is destroyed (underneath too) front bar is also heavily damaged.

So I need to do some repairs and the plan is to get back to lakeside for the end of august. I've bought a 70mm billet TB and some 440cc injectors. Thinking about some cams too. After that maybe a rotrex or a turbo. 450hp on std engine sounds pretty good to me.

Thanks Guys,

I was after something a little different after my last engine gave up. It's a K20Z4 and gearbox. Plan A was a Kawasaki zx14 engine/gearbox + turbo. Was deemed too hard/not reliable enough. Enter Honda power.

I've got a heap more pictures and details I'll update later. It's actually pretty involved getting one of these in there. Especially when you ram it this far back to improve the weight distribution.

Will also have a 125hp shot of nos to get it moving on the drag strip for Jamboree this year,

Well it was an eventful end to the year. A very wet track was no good for PB's but I managed to be at least 3 seconds a lap quicker than zuboo and miles ahead of the rest. Another First in Class and First outright for the day. This being the 6th and final round I also received 2 first trophies for the Season. The Zuboo boys cleaned up. There is another 2 trophies from the street series too.

Multiple excursions off the track, including getting beached in the rocks after turn 1. After the final session the engine started to get a be hot. Could be head gasket or could be some damage from the rocks into the radiator. All in all the engine felt brilliant. Couldn't be happy with the $200 block.

Now we rebuild for next year

Got off the dyno after a little check. Pinged coming on boost and was the same up top. Pretty reflective of slightly more CR. 192hp on 11psi. Actuator pressure brings the boost on pretty gradually. Given the stock engine, might be for the best. 7200rpm limit, stock 5efe

I didn't know any of you guys followed WTAC, I've been heading down the last 5 years with the Mighty mouse honda CRX. He managed 3rd in Pro AM.

I had my doubts about how quick the sva car would be but it certainly proved itself with a 1:29 with all the obvious issues they were having. Was gutted watching the driver have to run across a live race track to get his own fire extinguisher as the car burned

Andy Forest was a top guy to chat to. One of the friendliest guys I've ever met. He did absolutely everything he could to get another box in it for Saturday but it ended up being far too much work. Had a good chat to his wife too. Holy shit that woman knows her subies!

WTAC is definately at the pinnacle for time attack racing.

1.6's mostly

I haven't been deterred. Trying to think of a way to progress in the future, I have bought a toyota paseo to keep me going in the mean time.

170 000km 5efe Auto

Bolt-ons baby!

It's at the dyno now for a conservative tune. Should hopefully see me out the year of racing.

11 months of updates in an Hour!!!

Last Month I headed out to the 5th round of open sprints with some new tires. Just so happened porshe had a club day on at the same time. Finished 2nd outright only to lose to a radical and 1st in class. Managed to turn 5 laps before a big end came knocking...

Results: A few shattered Porsche egos. Ben came in just behind me in the zuboo racing k20 swift.

New 205-50-15 Yokies!

1x spun big end 3x severely worn big ends, 1x damaged crank, 4x marked pistons and bores and shredded oil pump as well.

Next up it went back to the Drags for Jamboree.

I got 3 qualifying runs in. an 11.4 and 2x 11.2's with a badly slipping clutch. I turned down the boost for Sunday eliminations to fix the clutch issues which worked. We ran Chicago shootout for eliminations. I won the first 2 rounds. Final round I was against Josh where he let me win but I still managed to screw it up and break out pulling another 11.2 on an 11.3 dial in all with less boost and a worse launch

You can hear the 2-step. It builds around 8-10psi quickly

Clutch slipping badly

Final eliminations and return road.... I still dont get why it went this quick. Turned down to 260hp

Trip to the dyno in August. Installed a 3 stage switch for boost selection and a 2-step rev limite + steering wheel button. 3-way switch on dash lets me selet what the button on the steering wheel does. It's either a 2-step rev limiter or an overboost button which reverts to the highest map.

Was interesting... Boost controller died, tps died, spark plugs died, clutch slipped, injectors maxed, turbo pretty much maxed.

Last time on that dyno actuator plumbed directly to turbo it ran 184hp on 14psi and 242hp on 20psi. Im guessing it was a little low, it was on semislicks and also ran 11.1 @ 124mph on that tune

This time the boost controller blew a hole in it's side and oozed molten plastic out :s (yes it went through the floods in 2011). Tried to run actuator pressure through a new controller. Boost crept up to 18psi. It was extremely gradual and pretty much exactly what I wanted, just a little high hp (247 - Blue line). So that's with both boost switches off. Boost setting 1 we mimicked the last curve the best we could pulling boost per rpm. Same peak hp but meatier in the middle. The second setting I wanted everything. I left the wheel alignment in circuit spec because, well, i'm lazy, and it wheel spun. We strapped it down hard over the to of the hubs. Green line is 20psi/260hp. Red Line is 22psi/275hp where the clutch started slipping. The boost comes on late due to restricting to get the clutch to hold. My injectors were 95% duty at this point and with the clutch we decided to leave it there.

We set the 2 step up at 5000rpm. It makes 10psi almost instantly. I rarely drag race and don't have a clutch position sensor, wheel speed sensor ect, so we left launch control alone. The cool part is Matty wired up a three way switch between the steering wheel button and the autronic. So with the switch up the button activates the 2 step. When its down it operates as a 'push to pass' where regardless of which boost setting I'm on, It will switch to the full boost map while depressed. This is what we used on the dyno to get over that peak torque point before throwing 22psi into it. That's the 1000rpm lag in the curve.

I went out to willowbank last week for a play (slippery) and ran a 11.5 @ 120mph with the 20psi tune. Ran great all night and fairly consistent. I've thrown the extra 2psi in it for Jamboree. I guess I'll see on the day if the clutch holds (It also went for a swim in 2011).

Also tested our United E85. Came up 90% ethanol and 10% good looking petrol (Honey trickle). Tested some Caltex E80 and it came up 75% Ethanol and 25% Pink petrol.

I re-did my center console and added 2x new switches for 3 stage boost control. Also added a button on the wheel for a 2-step. Also got carried away with heat proofing my radiator and added a panel to the head. Doubt it will do much but all the time attack cars seem to be doing it

New 3" side exit exhaust and gold reflective heat shield.

A little video from April. Still sorting the setup out a little but was running smoothly. Clutch was getting hard to disengage.

My efforts from June. New Springs had sagged as they settled in causing all sorts of issues. My driving was terrible all day. Car had big oversteer issues from the start of the day. Was dragging the splitter really bad down the straight so had to take it off. Removed the rear wing to balance it out. First flying lap, lost it at the apex of turn 1 and went sliding into the center of the track. Cracked the front bar in many places, ripped a cannard off and broke one of the mountings. Dropped the boost for the last session and ran the quickest and smoothest runs of the day. Pulling into the pits at the end the clutch failed to disengage and is now stuck on.

Here's a quick clip I threw together. Pretty bad driving in this session but 2nd quickest time with the last lap.

Round 3 open sprints on Saturday In July. I think I've got the car sorted now. Got fastest in class and fastest car outright with a 59.3 on the Clubman, and all on acutator pressure. Ben in the Mk1 Gti got 3rd outright and class win. Zuboo got 4th outright still chasing setup issues. Massive thanks to Ben, he watched me roll into the pits having delaminated my dunlop slicks and still offered to loan me his advans. Went nearly a second quicker on worn195 A050 semis (mediums) than the 220 soft dunlop slick. I was rather surprised.

In the lead up to this I removed the rear sway bar completely, reset shock dampers and lifted the front of the car 20mm. Also cut down the front splitter to only 100mm. I fixed my clutch issue and corner weighted the car. At jamboree 2 years ago it was 698kg. It is now 764kg. Bigger rims, tires, brakes, Aero, bracing, front section rollcage, along with headlights has added a combined 66kg The corner weights were pretty far off this time. Adjusting the height in the rear evened out the front. Still 68% front bias is not great. Also had a billet cover machined for the dizzy.

It's been a full on year for sure. My Son was born January 21st so racing had to take a bit of a backseat. I focused on winning 1 sprint series for the year with 6 races. There's only 1 race left for the year and I've won 5/5. Here's whats been happening

New sideskirts finished. Lighter than stock and help channel air away from the front wheels.

Just read from start to finish

The attention to detail is ridiculous and nothing but purposeful, tasteful mods...

I'm very interested in the modifications made to your rear diff to shim camber and toe. Any chance you could pm me some more pictures and info? If you have any plans for your baffled sump I'd be keen too. I run a sump that is welded around 3/4 the perimeter of the plate but have just lost a forged 5e due to oil starvation through corners. Is your sump effective or did you still find you had to consistantly run more oil in it? I'm looking at the morrosso accusump setups at the moment. They seem cheap and effective.

Cheers

Harry

Thanks guys. Weather is almost always like this.

After Jap nats, I've rebuilt another gearbox + new seals and bearings. Got the clutch checked and master cylinder checked. Also had the clutch slave cylinder sleeved down one size to increase the throw on the clutch. Ive always had trouble with the clutch never fully disengaging and this seems to have solved it. Also finished the dive planes on the front splitter. Replaced the rubber trim on the air dam with aluminium which saved about 1.5kg and also allowed me to shave another 40mm off the lip while keeping the same size. Cannards are very solid and attached to the bumper. D Zues clips attach them to the new HDPE end plates. I really wanted to keep it easy to pull off and work on at the track. Just need to get some better looking fittings for the ends.

Next time attack meeting is on the 8th of November. Just need to block the rest of the holes in the bumper and it should be ready to go.

Went out on fresh Tires yesterday. Taking it easy scrubbing them in saw the car go a second faster than previous PB. The car now has horrendous understeer. I think the increase in camber and stiffer front springs has stopped the car rolling over as well. The car felt extremley stable though. Pretty happy with the aero. Just needs a few more suspension tweeks. Unfortunately the dash decided to reject the 2gb memory card and not record anything. Updated the firmware and put in a new card. Should be fixed now

Zuboo had a steer in session 3 and knocked another second off the lap times, even with the extreme understeer. I came 5th outright for the day and Zuboo got 4th in the swift out of an 80 car field

1st place Hairy lemon time attack evo and 3rd place s13 silvia. Zuboo stayed on their ass for 4 laps straight.

Tried to get these videos side by side but gave up after a while.

The clutch gave up after session 3. Now has a serious vibration and wont disengage properly. I decided to bite the bullet and finally build the box properly while its out. We have just over a month until maximum attack meet

Since Jamboree I've been busy converting the car back to circuit spec and working on some aero. Ill be out testing at Queenland raceway this saturday and again next wednesday night.

The splitter clips onto the under body brace and then 4 d zeus clips hold it on. I can stand on it so it should hold a significant amount of weight. Rear wing is a 2d 57" carbon item. If testing issuccessful, Ill duplicate it in carbon. Data logging should show how much speed I loose down the main straight with drag vrs any increase in corner speed.

Jamboree came up last month so I decided to change it back to drag for a day. I made the the quarter finals but a worn 2nd gear synchro saw me knocked out. I got a shared light of the night with a 0.001 second reaction time.

Been working on refining the setup for time attack lately. Finally finished the front of the cage and painted the interior. Stripped more wiring and installed proper headlights for night racing.

Brakes finally arrived. 280mm discs with willwood 4 pots and carbon metallic pads.

Buddyclubs and slicks. Decals removed ready for new graphics!
