sorry dale I don't like to post dyno graphs, as my tuner ramps the car up different to avoid horrible wheel spin and the graph seems laggy if that makes any sense 2 you? so dnt want to start a shit fight.

but on the road it comes on a lot sooner then what the graph shows.

and old tune was actually 442 at 22psi. now 485 at 22 lost around 30hp in mid at 4500rpm but obviousily gained 40hp up top. pickup car this morning so see how it drives soon.

peak power went from 6600rpm to 7200rpm

What cams are you using?

camtech 272 9mm lift, purchased package thru lewis engines in SA

Make sure your cams have been dialed to the lobe centre Camtech recommend.

I recently had an issue with their product where they admitted to me that they grind as close to the stock base circle as possible, and that it is the customers responsibility to dial the cam. Camtech cams are NOT drop in.

well speaking of that, Iam getting a weird noise from my left tappet cover :( but in saying that, I got the camtech 272 custom made with vct still which allowed me to use the stock inlet cam gear, on another note the exhaust site has an adjustable cam gear. which wasn't dialled in.

I don't really have access to Hypergear's services, it would mean taking my car off the road for several weeks and shipping it to them and back. I had heard that enlargening the internal gate was common these turbos, how hard is it to actually do? There are several machine shops around here that could probably do it.

The stock intake gear is adjustable.

I recommend you contact Camtech and ask them where peak lift should lie for each cam. You can then get a degree wheel and dial them in.

oh ok thanks for that, might have to book in with my tuner get him 2 sus it all out after powerplay. but for now, car is on full song at 4500 and pulls pretty good specially up top. and idles nearly factory.

There are bolts on the back of the gear, its adjustable just like an actual adjustable camgear is.

Yep, except you have to take it off to get to the bolts. Its like nissan just want to annoy us!

LOL am not 100% sure about this but I THINK you can remove the rear dust cover which will give you access while your working. Then mark the belt and the gears after its all timed right and reassemble.

I have not tried this personally, am just going off my knowledge of what the motor looks like as you pull it apart.

Haha yeah but you do that before you adjust it, then use the dial gauge to adjust it and f**k around, then put it all back together.

A bit of a procedure but it will save you taking the pulley off every time to adjust :)

Just use a paint pen to mark the belt and gears before you take them off, should be fine!

I hope they strapped it down properly, apparently HPF don't bother strapping cars down at dyno days as I found out yesterday. :/

I wonder if that's the reason some people never get the figures the are chasing? Wheel spin can give some very weird results...

I never got around to putting it on dyno :( my third gear is pretty much stuffed lol, crunches going in and down shifting, its horrible, only got 1 run at test n tune due to drag car flipping in the deep end, done an impressive 2.6 60ft and 3rd took 4 times to go in crunching :( haha, 13.0 at 122, guess i didn't beat my 12.3 at 120 from couple yrs ago grr, if i got 3rd it woulda gone 125 easy :( all in all, drove 1000kms, flog it all weekend, 8000rpm all day long in 35 degree temp, and got me home :)

Bugger, sounds like a frustrating weekend :( 122mph with issues is certainly moving though! What changes has it had since it ran 120mph?

Glad it at least survived the trip. As an aside, there is a turbo builder in NZ (who isn't necessarily the most stand up in terms of honesty at times - makes it hard to know what to believe and what not to) who has been trying extinguish any interest in the Kando turbos presumably before they get too popular, saying they tend to fail before you get any good use out of them. I haven't seen any evidence of this anywhere yet, but figured on this large a community it should be a mature enough trend here to get a reputation one way or another. Has anyone actually had one fail, or even get a bit sad yet?

Drags this weekend coming, can't wait to see what the 16G setup does - I should add that the turbo is not "all in", boost is limited to what can be safely run with a 2.5 bar MAP sensor

    • 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.
