the way i worked it out was its probably revving to about 7000, maybe a bit less like most ppl do...

the graph doesnt show RPM but it does show rod speed.. so if 180kmh is close to 7000, 90kmh is close to 3500.

its a few rpm off but close enough, boost is definitely well and truly on before 4000. a good achievement.

no way 3500 is 90km :no:

Anyway out of curiosity and boredom I just laid my dyno sheet next to battery's..

Im sure many of you have done this already.. but im posting it.. :D

Not alot in it really, they are running almost identical boost , I have a fair bit more midrange torque and an extra 20kws at 5k, but nose over after 6k where they are both pulling 300kws,

Then he keeps pulling past 7 and smashes me..

Just remembering though I have alot less mods under the bonnet <<read excuse for losing... :Pbatterydynosheet.jpgtune300.jpg

Im not gunna bother comparing anything to Simons freak of nature....

well know how many revs it is if we know where the run ends.. speed and RPM are always relative. you will do double the speed at double the revs in the same gear etc.

nice comparo too :) i cant wait to pop a 20G on my SR

Aaww don't be sad Simon you know your my hero.

Its more the fact I can't be bothered converting all your dynosheet figures to something legible. :laugh:

I think u were making the same as me at 5Ooorpm

On low boost mine is about the same as yours at 5000rpm, high boost close to 30kw more

You guys need to screw more boost in... 2bar or bust :)

Edited by SimonR32

Yeah you can see my 20g making more on the green line but that was 21.5 psi which is 4psi more than the blue line and the gains were insignificant..As Roy said the little comp just can't push any harder ,its giving all she can give..especially on my setup..If I get a better manifold and plazmaman plenum and better cooler it could possibly push for a little more.. But looking at the comparison I would sooner just get a T67 than push this any further.

Not sure why battery didn't push more in..

Got a scanner Artz? I think I could use my broken ass Photoshop skills to overlay onto the same image..

Just re did all my cooler piping in 2.5"(was a mix of 2.25/2.5" before) and now i'm thinking maybe I should move to a bigger Throttle body, not sure if there is much point cause the stock one is still bigger than the 2.5" piping ??

Haha I was putting mine over a picture of yours on the computer, I was gunna trace it but gave up..its almost identical though with yours just dipping a Little between 4-6rpm

That's the same size as my cooler piping I guess there is hope for it yet :D

Got my T67 today and have a few questions.

It came with a 4" Anti surge compressor housing which i did not want i wanted a standard 4" Compressor housing. Will this matter that much?

What is the best way to block the water lines? The shorter of the 2 (Water return??) I was simply going to find a bolt wth the same pattern but shorter and bolt it in nice and tight with a coper washer.

Not sure what to do with the one that goes around the back of the block should i just cut it off shorter and fix a blocked off bit of hose on the other side? Or blank it off at the source, which im guessing is under the plenum?

Any help is appriciated keen to get her back together, tonight i have connected oil feed(One supplied with the turbo is a bit long) and return. Finished replacing exhaust manifold studds.

Also I have one of those NZ manifolds and i am not happy with the way the wastegate pipe comes out it is really really close to the body and air con lines.

Should i modify this pipe or just blank it off and run the gate off the turbin housing?

is this one of the mild steel ones from ebay? i was pretty keen to get one of these for my rb20 anymore negatives?

    • I had 3 counts over the last couple of weeks once where i got stranded at a jdm paint yard booking in some work. 2nd time was moving the car into the drive way for the inspection and the 3rd was during the inspection for the co2 leak test. Fix: 1st, car off for a hour and half disconnected battery 10mins 4th try car started 2nd, 5th try started 3rd, countless time starting disconnected battery dude was under the hood listening to the starting sequence fuel pump ect.   
    • This. As for your options - I suggest remote mounting the Nissan sensor further away on a length of steel tube. That tube to have a loop in it to handle vibration, etc etc. You will need to either put a tee and a bleed fitting near the sensor, or crack the fitting at the sensor to bleed it full of oil when you first set it up, otherwise you won't get the line filled. But this is a small problem. Just needs enough access to get it done.
    • The time is always correct. Only the date is wrong. It currently thinks it is January 19. Tomorrow it will say it is January 20. The date and time are ( should be ! ) retrieved from the GPS navigation system.
    • Buy yourself a set of easy outs. See if they will get a good bite in and unthread it.   Very very lucky the whole sender didn't let go while on the track and cost you a motor!
    • Well GTSBoy, prepare yourself further. I did a track day with 1/2 a day prep on Friday, inpromptu. The good news is that I got home, and didn't drive the car into a wall. Everything seemed mostly okay. The car was even a little faster than it was last time. I also got to get some good datalog data too. I also noticed a tiny bit of knock which was (luckily?) recorded. All I know is the knock sensors got recalibrated.... and are notorious for false knock. So I don't know if they are too sensitive, not sensitive enough... or some other third option. But I reduced timing anyway. It wasn't every pull through the session either. Think along the lines of -1 degree of timing for say, three instances while at the top of 4th in a 20 minute all-hot-lap session. Unfortunately at the end of session 2... I noticed a little oil. I borrowed some jack stands and a jack and took a look under there, but as is often the case, messing around with it kinda half cleaned it up, it was not conclusive where it was coming from. I decided to give it another go and see how it was. The amount of oil was maybe one/two small drops. I did another 20 minute session and car went well, and I was just starting to get into it and not be terrified of driving on track. I pulled over and checked in the pits and saw this: This is where I called it, packed up and went home as I live ~20 min from the track with a VERY VERY CLOSE EYE on Oil Pressure on the way home. The volume wasn't much but you never know. I checked it today when I had my own space/tools/time to find out what was going on, wanted to clean it up, run the car and see if any of the fittings from around the oil filter were causing it. I have like.. 5 fittings there, so I suspected one was (hopefully?) the culprit. It became immediately apparent as soon as I looked around more closely. 795d266d-a034-4b8c-89c9-d83860f5d00a.mp4       This is the R34 GTT oil sender connected via an adapter to an oil cooler block I have installed which runs AN lines to my cooler (and back). There's also an oil temp sensor on top.  Just after that video, I attempted to unthread the sensor to see if it's loose/worn and it disintegrated in my hand. So yes. I am glad I noticed that oil because it would appear that complete and utter catastrophic engine failure was about 1 second of engine runtime away. I did try to drill the fitting out, and only succeeded in drilling the middle hole much larger and now there's a... smooth hole in there with what looks like a damn sleeve still incredibly tight in there. Not really sure how to proceed from here. My options: 1) Find someone who can remove the stuck fitting, and use a steel adapter so it won't fatigue? (Female BSPT for the R34 sender to 1/8NPT male - HARD to find). IF it isn't possible to remove - Buy a new block ($320) and have someone tap a new 1/8NPT in the top of it ($????) and hope the steel adapter works better. 2) Buy a new block and give up on the OEM pressure sender for the dash entirely, and use the supplied 1/8 NPT for the oil temp sender. Having the oil pressure read 0 in the dash with the warning lamp will give me a lot of anxiety driving around. I do have the actual GM sensor/sender working, but it needs OBD2 as a gauge. If I'm datalogging I don't actually have a readout of what the gauge is currently displaying. 3) Other? Find a new location for the OEM sender? Though I don't know of anywhere that will work. I also don't know if a steel adapter is actually functionally smart here. It's clearly leveraged itself through vibration of the motor and snapped in half. This doesn't seem like a setup a smart person would replicate given the weight of the OEM sender. Still pretty happy being lucky for once and seeing this at the absolute last moment before bye bye motor in a big way, even if an adapter is apparently 6 weeks+ delivery and I have no way to free the current stuck/potentially destroyed threads in the current oil block.
