We don't get offended since we have been making more power for so long that we are genuinely happy every time you guys crack a little more power than stock...... :P

AFM = Air Flow Meter

MAF = Mass Air Flow

AFM = MAF

..ahem..a little more power? i think scotty and jetwreck have both achieved a bit more than a little :)

I'm surprised no-one has bitten on this comment, as I run into all the time I'll end my rant now :/

Everyone was a bit slow to bite there Bis.

Sorry Jet that was being directed at whitestag's query. (I'm pretty sure you are saying derr)

lol.....I did write a couple of responses.....but there is no real come back.

Your right....heaps of parts straight off the shelf to build a decent tractor motor....sorry RB.....hey after 20-30 years of the motor being on the market getting 270 AWKW's reliably out of one of them without cracking the motor open and with the same turbo housings should be easy aye!

lol.....how did we get here from AFM :/

Yeah, but isn't that almost what Scotty is doing anyway?

Funny thing but AWKW and RWKW readings are almost always identical unless there is wheel spin. Sure people add 10kw or so to their figures but I take that with a grain of salt...in fact all dyno numbers as well.

The R33 is in RWKW cos it only has one diff and doesn't struggle for traction (in a straight line at least). Obviously the stagea was missing its front driveshaft for the dyno runs. It grips up fine with it back in.

some of the C34 guys get a little confused.....I give you a heads up as they don't quite get it :( ......our car is 98% different to the C34! So when you hear the line "Well on my C34......" more than likely they are completely wrong with the assessment!

Sorry in advance if I have offended any C34 owners :P

98% different hey?

I was going to say: "Well on my SR20......" I was right anyway, despite the fact that I own a 4 cylinder. BAHAHhahahaha.

AND it still ended up being the AFM!

:D what error code comes up and how do you get it with your SR20!

here's one for you.....the C34 has a shit load more in common with a R33, R34 yes?....or would you say the C34 has a lot more in common with a 350Z!

and congrats on the diagnosis........your a rocket scientist aye! :)

I've got the factory MIL light on the SR20 fitted to the 1600. Never use it though.

I just plug in the nistune software and it tells me the fault codes. Pretty easy and highly recommended.

C34 has a motor in the front and so does the M35. Both are made by Nissan. Both have an AFM and by the sounds of it, have a limp home mode. That's enough commonality for me :bunny:

Rocket Scientist? Nah, just willing to help a nissan brother out...

      Mistakes were made, my R34 Story

      By Kinkstaah · Posted

      I don't know it is due to that. It could just be due to load on track being more than a dyno. But it would be nice to rule it out. We're talking a fraction of a second of pulling ~1 degree of timing. So it's not a lot, but I'd rather it be 0... Thicker oil isn't really a "bandaid" if it's oil that is going to run at 125C, is it? It will be thicker at 100 and thus at 125, where the 40 weight may not be as thick as one may like for that use. I already have a big pump that has been ported. They (They in this instance being the guy that built my heads) port them so they flow more at lower RPM but have a bypass spring that I believe is ~70psi. I have seen 70psi of oil pressure up top in the past, before I knew I had this leak. I have a 25 row oil cooler that takes up all the space in the driver side guard. It is interesting that GM themselves recommend 0-30 oil for their Vette applications. Unless you take it to the track where the official word is to put 20-50w oil in there, then take that back out after your track day is done and return to 0-30.

      Nice, looks great. Nice work getting the factory parts also. Never know when you'll need them.

      I take it that the knock retard is from bearings tapping a little tune? Thicker oil is a fragile bandaid. You need a much bigger oil cooler and probably the bigger pump being discussed.

      Hi @Chupapy i had several leaks from coolant pipes being corroded, i also had one leak on back of the head onto transmission. For me that leak was from the turbo water line. Follow the line to the back of the head The hose and metal pipe had perished these are the best pics I took of it at the time
