When mine had a horrid amount of end float, AKA no preload. My diff just got super crazy noisy. Inspecting the gearsets while apart and they seemed fine, still are 20,000kms later or whatever.

What duty cycle do your injectors get to at the moment? Maybe try go way bigger spray just on open valve period rather than back of valves? Staged injection + variable length runners? Methanol?? I reckon it would be interesting to setup a pressure sensor on an exhaust runner, and then find out if you see pressure peaks/troughs like you do on the intake side. You could find out the actual tuned length of the manifolds you've made. Then it might tell you a tale about needing to be a lot shorter or a lot longer. (or it might be sweet as is!) I remember somewhere seeing someone do this. They had a screw in fitting which then had a long hard line coming off it with a long coiled section in the airflow to dissipate the heat before it gets to the sensor. From memory if you're doing it right the exhaust pressure only goes up to 20psi or something like that. Can get an 80psi sensor cheap enough.

You can also weld them to your car, for a poor mans air jacks

True but why go to these lengths when you can just buy one brand new for 3 bucks or whatever. I paid one of the pro diff shops to sort mine out, and they fucked it up so bad. probably 5-6mm end float on the pinion because the splines were grabbing before the torque tube was reached. How could you not notice that??? They also hammered the torque tube back out instead of replacing it. Frustrating when you expect to get a good job done for paying $$$ and then have to do it yourself anyway.

Toyota manual says dont ever reuse torque tube, even if you back off the nut slightly its a throw away item. Also, I had a problem where even though the torque tube was torqued down to spec, I had a shitload of end float. Turns out that the splines were jamming before the torque tube squashed up, hence the float. So take the tube out and make sure splines move freely on one another. lold at the tyre valve!! Random.

That looks really good! I've been talking to Snoozin about taking these somewhere to get polished, but the thing is the wheels are pitted from lots of corosion from sitting so long. So I've been getting in there with an air powered random orbital sander with 240 grit stick on discs. Have managed to get most of the pitting out, with a brute force approach haha. Because of the shape of these wheels it's actually stupidly easy to do these with the power tools. My impul wheels I couldnt do the same as there are nooks and crannies you couldnt reach. Even just that so far and they're starting to look heaps better, will need to get some stick on sanding disc things in higher grades and see how that goes. May require some hand finishing but for the better part should be able to plow through it with the air tools / polishing pad / etc.

Dont stand in it though. You might get etchy feet.

It looks like they will be reasonably easy to get looking decent without too much hand sanding/polishing/etc.... The only issue looks to be that since these wheels were in especially crappy condition to start with, some of the existing corrosion/scratches on the lip of the wheel looks too deep to really sand out. Bummer. Should have started with a better set, lesson learned. I started using the rear of the car jacked up to polish the (tiny!) lip on one of the wheels so far and seems pretty good results on that. Because the faces of the spokes are flat, and there's nothing in the way, it will be super easy to use sanding pads/buffing pads/etc on the centre spokes to get most of the way there I think. However this is a seriously tedious job that is zero amount of fun, haha. I'm cringing at thinking how much time this is still going to take! There's zero chance of having these ready for putting tyres on by tomorrow for akl OS meet, which was my goal from a few weeks ago.

Not sure yet. The finish currently looks perfect for paint adhesion, so I'm considering options for painting first and polishing the polishy bits afterwards before they get dirty. The type of finish currently on the wheel, definitely isnt appropriate to roll as is. It looks like it would pick up a crazy amount of dirt/brake dust, and it's obviously a very dull looking finish. So it isnt a magic bullet that gives you a wheel thats ready to roll, but my opinion so far is that it's an option to consider if you dont want to spend a million hours cleaning wheels. It does look like it's etched away some amount of the surface of the wheel all over, as previously there were faint machining marks on the "polished" surface of the rim that are now gone. So keep this in mind if you have some wheels that have some racing legends signature hand engraved into a spoke or something like that, it may slightly deteriorate very fine details. When/if I buy some other wheels like starsharks or whatever, if they need restoring then I'd consider going down this path again. It's a good process for something that has a lot of detail (like mesh wheels) with complex patterns which are difficult to clean mechanically. I probably wouldnt try this on something like a Hoshino G5 or SSR Mk1, because you've got to polish up an absolute shitload of the centre of the wheel again. Something dishy like a starshark where you polish up the lips anyway, and only small details on the spokes are polished. Seem like a good contender for this process.

I have seen a few threads about people getting wheels sand blasted, or paint strippered, or oven cleanered, or whatever. I have had some MA61 celica/supra wheels which looked like absolute trash, they look like they had been under the ocean for the last 30 years. I took them to powerstrip in Penrose, $230 for 4 wheels to be stripped completely clean and I'm fairly impressed. It took about a week because they need to soak in a tank for ages for the process to work. The surface finish is now something like 800 or 1000 grit sandpaper, they certainly dont come out shiny. Considering that these were caked with dirt, and painted, and stained, and whatever else. I think it has been a worthwhile process. As it would take many hours of sand blasting/degreasing/etc to acheive the same thing. Will report back to this thread when I get them polished etc. Previously: Now:

Haha yeah maybe oldschool drags this year? 3AU showdown. I'll get an epic launch with the super boaty suspension. Could possibly even break traction. Maybe.

Start working on the repairs while at the meet, and we can all stand around nodding authoratively as though we know something about trumps

Hmmmmmmmm reading this makes me want to dig the yellow car out of the garage and take it for a spin. Words I never thought I'd ever utter, but the 3AU in the yellow car is actually really nice to drive. It possibly has the worlds smoothest T50 as well, because it's never had any power through it hahaha.

It would be interesting to get your fuel map dialled in, and then see what the shapes look like. I reckon you're probably now at the point where only a few mm worth of changes to runner length will make a reasonable difference either way. Or something else to think about. Similar to how boost is a sign of restriction, as in, the head cant consume all of the air that is provided by the intake manifold. In an NA car you get a pressure drop when the head is hungrier for air than what the intake can provide. Perhaps you're at the limit of the ITB size/setup? Maybe its at the point where bellmouth shape has become super critical and you're getting Or that things like rounding the leading edge of the throttle plates and smoothing down the bolt heads. Or maybe whatever you do from here, the pressure will always drop because the airspeed in the runner is so high that you get a venturi effect bernoullis principal or whatever, pulling air out of the map sensor hose so it always reads lower as the airspeed increases. Have you considered fitting a beams 3SGE intake manifold? To make it fit you may also need a beams 3SGE head. And block.

Was part of the design brief, to make it look like a cock and balls?

+1 to the sentiments above! Good to hear you've come out of your troubles okay. Look forward to seeing some more progress on this car, it's great.

Wheels are cool but you need the mexican paint job to go with it

In dissapointing, yet exciting news. Shortly after purchasing the nitrous setup, I made a decision about something else which means it will be up for sale shortly. Pooz! The reason for this is exciting though! I am going to enter the next season of Superlap. If you're not aware, Superlap is basically this is a string of glorified trackdays, but with official timing with transponders etc. You race (against the clock) for points across the season. Six events, one per month starting December. Nitrous is banned from this, and I'll need every penny I've got in order to make it to all of the rounds. So I made the decision to pull the plug on the nitrous. Superlap starts at Hampton normal track, (cool) Then Taupo full track, (My favourite!) Then Manfield (Never driven there, looking forward to it!) Highlands Park (!!!!!) Taupo half track (Not my favourite, but still fun and will actually favour my car compared to full track) and then Hampton FULL TRACK for the final. (Hell yeah!) So this is a good foot in the door to get to some new venues. Which to me, is a lot more exciting. I'm really excited about this! If you're not familiar with Highlands Park, it's a fairly new track that's down in Cromwell. It's heavily constrained in terms of how many events it can run, only a handful per year because of noise restrictions from the council. It's also set against an amazingly beautiful backdrop in one of the best parts of the country. So any opportunity to get on the track is worth taking. I'm going to take a week off work each side of it, and go on a camping trip around the South Island. It's not until February, but have started making some preperations already as it's a bit of a hike even if I take the shortest possible route: I've never had a spare tire, so this is high on the list for obvious reasons. I borrowed some 20mm spaceers from Sheepers to test fit to see if this helps with brake clearance. 20mm spacer now means that I can fit some standard Toyota alloys, hooray! Which is convenient as we've got 8 of these kicking around haha. The only problem is that the wheels that I've got currently look like they've been under the ocean for the last 20 years. So I've spent bloody ages today scrubbing up one of them, nearly ready for some grey/silver paint on the non polished bits. I'll fit some nice cushy long wearing 195/55/15s on them that will make the car nice and comfortable for long trips. Apart from a 2nd set of wheels I need to make some careful considerations about what tools and spares I will need to bring. Some of the cars in street class have 4x or more that power that my car has, super wide tires, more modern suspension, aero mods, etc etc. Lots of turbo 4WDs, especially in street class as they can make the most of tires limitation. So it'll be cool to bring some 80s flavour to the event, and try hustle some of the more modern cars out of some points haha. It's going to be so much fun! Actually cant wait.

Yeah gutted! Good news though is that now that Playday on Track has been booted from Hampton. They are running a HEAP of events down at Taupo. Once or twice a month sort of deal. Which is awesome as previously it's always been hard to try and find trackdays there. A lot of that group of people are instead heading to the trackday on the 19th September: http://www.gpforums.co.nz/threads/511742-Taupo-monday-19th-september I'm still considering heading down. Have you driven on the track before Scrubb?

I wish someone could win lotto, and just pay Sheepers to build fuckin amazing cars all day. Hmmm. Maybe it would make sense if Sheepers was that person who won.
