Great meet last night! The location was super sweet and it was cool to head to the pub for a brew afterwards. Stoked to hang with everyone for my final OS meet as a Hamilton resident. Sounds like the owners of Mizoni were very happy to have us too .

See y'all tonight!

Jumped back in this car over the weekend after a year out of the saddle. We fitted a set of the new class tyres, Hankook Ventus RS4. These are more of a road tyre than the Toyo R888R tyres that we previously ran on. They're around half the cost of a set of Toyos and I wasn't sure what to expect from them. This weekend had the meeting split over two days, with 4 classes on Saturday and 4 classes on Sunday and a 30 minute test session for each class in the morning. I entered the SF Cup on Saturday (open clubmans type racing) and the MX5 cup on Sunday. Straight out of the box, the tyres were proving to be quick. I set a lap time of a 1.24.6 in testing, which is right in line with the times we were doing on the old tyres. I didn't get any photos or video from Saturday as I was busy getting back into the groove of racing. Had loads of good battles with a bunch of drivers I wouldn't normally be on track with. It's fun racing against all types of cars! Turns out MX5s, VT SS Commodores and BA XR8 Falcons are all similar pace, but they develop their speed in very different ways. My fastest lap for the day was a 1.24.2 in the first race and Jerry did a 1.24.1 in his pink #777 - the quickest I've been on Toyos is 1.24.0, so these Hankooks have potential! Sunday was another intense day of racing with variable weather to add to the excitement. We were greeted by showers and a greasy track. A good chance to test the new tyres in the rain! They were much more predictable in the rain than the old tyres and I was able to hold the car VERY sideways without spinning out. Good news from a drivers and spectators perspective. I qualified on pole in the greasy conditions, but didn't quite have the pace in the first race, dropping back to third. My camera battery was flat, so I didn't get any footage. The second race was reverse grid, so I was starting third to last in position 12. After a hectic couple of laps in traffic, I managed to pop out in the lead and hold that to the end. This was the first win I've had for a couple of years and the chocolate fish tasted sweet! Onboard footage from Race 2: Race 3 was a staggered start race with the slower cars to the front. Jerry Hoskins in the pink car 777 was right with me through the whole race. We traded positions a few times and then attempted to make our way through the traffic. We didn't quite make it to the front, but I managed to get up to 6th which gave me an overall round win for the weekend. Onboard footage from race 3: It felt good to be back in the car and was great to get a win! I'm moving back to Palmerston North very soon, so will be doing as much motorsport as I can.

Looks like there's something good happening here. How many KW difference at this point of the graph? Looks like 5ish kw to me.

I’m keen for this. Need to get the MX50* out more often. *100

Fill that fuel cell up with Purple Goanna and we're on.

You should definitely come along @Kimjon! @Shakotom did it on an FA50 last time (disclaimer: FA50s are not recommended for this ride).

Haha, it actually sounds like a Harley! This thing is looking cool now, it’s crazy how far you’ve developed it. Most insane lime scooter ever.

Here's the new one that Murray just bought for his Integra. This is bigger than his original and has a few extra features: https://www.aliexpress.com/item/33022941096.html?spm=a2g0s.9042311.0.0.a8ef4c4d8WUncV

What car is it for? I run a small Shorai in my racecar and it's never had problems starting the car. My friend was running an aliexpress LiFePo4 in his K24A integra and it also worked well for a few years until the alarm flattened it a couple of times due to parking the car up for more than a month each time (they don't like being run flat).

So, does this mean that wave tuning is more important in the low/mid range and up top is all about mass flow?

Do you have any links to pics of these? I'm keen to see, but my google searches didn't bring up any photos.

Very sad to hear this. RIP Darryl / Sumo.

Wow, that looks really good! Much more balanced with the chopper wheel on the back.

The FS50 had Suzuki Lets wheels. The FA50 had Suzuki FS50 wheels. Both with standard tyre sizes.

Can you get a 6" hole into the plenum? 4" is too small.

Hey @Muncie, I see you’ve found a wheel now, but I have another option if you want it? It’s a fatty rear end from a mini chopper. The tyre is a 130-60-10. The whole frame is yours if you want it (both parts, unless @Kimjon wants the front end for a drift trike).

Yeah, it’s been a while! Should be a good load of updates coming soon... That pic at full compression was with a 12mm plastic spacer in place of the bump stop to simulate full bump stop compression. The bump stops are polyurethane foam and are designed to rise in rate as they compress (36mm extended length). Here’s my high tech method of finding full squish:

Posting these here for future reference. These photos are a year old. I spent a bit of time playing with bump stops, spring hats and keepers to make full use of my shock travel.

The September meet will be a little different. Thanks to @Beaver and @macabre for the future of our monthly meets. Copy/paste of the first post:

Nice! The results are basically as expected. Looks like a big tapered inlet has some potential? Cool to see the power climbing and staying level right up to 9k. We really need to get a Beams on that dyno... I’m curious to see the difference between 45-55mm on a 2L engine.

The easiest way to post a video is to upload it to YouTube and copy the share link. Paste that into your post and the forum should do thit rest. Keep up the good work by the way! It’s coming along well.

Come for pizza next month. Good meet y’all. Next month we’ll be at Mizoni Pizza on Maui St. Lock in September 17th.
