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.

Haha wow that's impressive! Never seen that done before.

Dunno how CAN works on the G4, whether it uses the cable that your laptop plugs into or two of the wires on ECU. But that could be an idea to get all of those things logged. Use something like this (just randomly googled analog to can converter, there are probably better things out there) http://www.techmor.com/analog-to-can-module-ac-1-4/ So you can get 4 or 6 or whatever sensors for only 2 wires. I think the megasquirt people make a pretty decent CAN converter thingy with lots of inputs.

Surely your ECU would already have engine temp hooked up, otherwise it would run like crap when it's cold. So RPM based rev limit will be really easy to setup. Do you have a cable to the ECU and PClink installed? Download a copy of your tune and post it up, I'm sure you'd have a spare input on a G4 if you're running ITB NA motor. It only needs 1 analog input for wideband.

You cant mix and match hubs and struts. Look for AA60 or ST141 struts and hubs. end of story. Coronas are just as common as cressidas etc so why would you bother with any other option when there's a common car available with identical suspension to yours.

This might have been a good time to replace the bearings...

You need to swap the whole thing, bearings are different sizes so hubs arent interchangable. Obviously need to do both sides as suspension geometry is different.

Some of them only lasted about a week or two! Then others only a month or two. It was an expensive process haha. I think it was mainly because I was sitting there for so long, tootling on the laptop before starting the car. From looking at the GUI for the controller the sensor takes maybe 15-20 seconds to fully warm up if the engine is off. So I think it's only bad if you're sitting there for a few minutes each time.

Oh yeah! Good thinking

Maybe you could have a relay triggered by the alternator charge light, so turns the sensor off when the light is on.

Yes you need to have it running while the motor is running or they crap out. When they're up to temp they burn off contaminants, I think they end up getting clogged if you dont.

Generally a good ballpark is 14.7 for cruising conditions (driving on motorway) and 13:1 for full throttle.

C & M performance do 10lb bottle refills for $250 + GST.

A G sized bottle would hold about 60 pounds nitrous... So 10 bottle refills. So $205 per refill if I did it myself, not including bottle rental etc. Oh wait plus GST. Yikes. Eeep! Did I say 60 shot? I meant a 2hp shot so it lasts longer haha. I guess can see why it's not such a popular option then. Maybe I'll use 1-2 bottles for lols then sell the kit again if it'll end up costing a billion dollars per week.
