ahhh john mate seen this beast come allong way...i member the day u droped the q45 in it...f**k it sounded good...good to see its all comin together well...ull have to take me for a spin once the blower and everything is on :) haha...cheers mate...top stuff!!

hahaha yeah for sure rob.

No updates for a while, sorta lost interest and drive for a little while as i had no idea when the computer was coming. But it left yesterday and should be here today. Hopefully fire it up for the first time tomorrow afternoon. Take it down the coast for a tune next week!! now im kinda of excited again.

Rob i got ur PM i will look into that, cheers.

UPDATE:

IT LIVES!! Fired it up last night, built up fuel pressure, turned it over and it idled like factory.. well it hunts a little with the blower and is a little rich... A test drive and some street tuning tonight.. Then a trip down the coast to be dyno'd.... It sounds unreal!!

Can forsee a few small problems with it... the rubber seals where the funny lookin manifold splits may leak.... Still have to put the engine damper on the calm it down... with the blower mounted so far to one side it ends up moving quite a bit, Fuel pump is farken noisy!! but i knew it would be.. mounted on the boot floor that now has no sound deadening..

All thats really left to do is pretty up the interior and do the cage... these are trivial though...

Well everything seemed to work out perfectly. It made 5psi from ~6k through to 7.2k where it just started to max the injectors out at 335hp@rears and stupid amounts of torque... car is very stupid to drive and overall im absolutely stoked... to take it any further id have to put bigger injectors and lower the compression, easy enough done... but it will do "for now"...

it makes progressive boost all the way to redline.

Going out to willowbank tonight for some shake down passes. Getting excited..

First time out on slicks should make things interesting..

ok well all worked out ok... kind of... couldnt manage under a 13 to start with but then we pulled the air cleaner off and played with some tyre pressures and the car dropped almost a second...

it managed a 12.42@112mph with a 1.7 60ft time

It wont change from first to second with out completely back off so it is loosing heaps of time there.. it kept going faster all night but andra kicked it off once it ran under 12.5 cause i didnt have front runners...

So i sourced some front runners yesterday wheels and tyres and they should be here by the end of the week...

Now i just have to sort the gearbox,, we may take it out for some more testing after power cruise before deciding which way we will head with the gearbox...

Options are speak to the guys in the states and send the valve body from the current gearbox over there to be modified, have a custom auto computer built for it and buy a big power handling rebuild kit for it.

And the other option is to make a Fully manualised C4 or turbo 400 bolt up... Either option is going to be really expensive... Im leaning more towards a built turbo 400 as parts seem to be cheaper for them and they are fairly cheap to get a ahold of second hand.

But this still means i will need to modifiy the drive shaft again and get another custom stall convertor built...

And at the moment i have zero cash... just waiting for the GTR to sell and then we'll see where we go from there....

More research is being done into a methanol enrichment system as well.... I want more power.. but first we have to get it down the strip with no headaches..

    • Have a look at that (shitty) pic I posted. You can see AN -4 braided line coming to a -4 to 1/8 BSPT adapter, into a 1/8 BSPT T piece. The Haltech pressure sender is screwed into the long arm of the sender and factory sender (pre your pic) into the T side. You can also see the cable tie holding the whole contraption in place. Is it better than mounting the sender direct to your engine fitting......yes because it removes that vibration as the engine revs out 50 times every lap and that factory sender is pretty big. Is it necessary for you......well I've got no idea, I just don't like something important failing twice so over-engineer it to the moon!
    • Yup. You can get creative and make a sort of "bracket" with cable ties. Put 2 around the sender with a third passing underneath them strapped down against the sender. Then that third one is able to be passed through some hole at right angles to the orientation of the sender. Or some variation on the theme. Yes.... ummm, with caveats? I mean, the sender is BSP and you would likely have AN stuff on the hose, so yes, there would be the adapter you mention. But the block end will either be 1/8 NPT if that thread is still OK in there, or you can drill and tap it out to 1/4 BSP or NPT and use appropriate adapter there. As it stands, your mention of 1/8 BSPT male seems... wrong for the 1/8 NPT female it has to go into. The hose will be better, because even with the bush, the mass of the sender will be "hanging" off a hard threaded connection and will add some stress/strain to that. It might fail in the future. The hose eliminates almost all such risk - but adds in several more threaded connections to leak from! It really should be tapered, but it looks very long in that photo with no taper visible. If you have it in hand you should be able to see if it tapered or not. There technically is no possibility of a mechanical seal with a parallel male in a parallel female, so it is hard to believe that it is parallel male, but weirder things have happened. Maybe it's meant to seat on some surface when screwed in on the original installation? Anyway, at that thread size, parallel in parallel, with tape and goop, will seal just fine.
    • How do you propose I cable tie this: To something securely? Is it really just a case of finding a couple of holes and ziptying it there so it never goes flying or starts dangling around, more or less? Then run a 1/8 BSP Female to [hose adapter of choice?/AN?] and then the opposing fitting at the bush-into-oil-block end? being the hose-into-realistically likely a 1/8 BSPT male) Is this going to provide any real benefit over using a stainless/steel 1/4 to 1/8 BSPT reducing bush? I am making the assumption the OEM sender is BSPT not BSPP/BSP
    • I fashioned a ramp out of a couple of pieces of 140x35 lumber, to get the bumper up slightly, and then one of these is what I use
    • I wouldn't worry about dissimilar metal corrosion, should you just buy/make a steel replacement. There will be thread tape and sealant compound between the metals. The few little spots where they touch each other will be deep inside the joint, unable to get wet. And the alloy block is much much larger than a small steel fitting, so there is plenty of "sacrificial" capacity there. Any bush you put in there will be dissimilar anyway. Either steel or brass. Maybe stainless. All of them are different to the other parts in the chain. But what I said above still applies.
