What dyno graph are you looking at?

At 2500rpm it's only making 130hp atw

G.J meant there was a power band of 2.5k where its making in excess of 500hp ie from 5000rpm to 7500rpm

Your obviously not reading it right because at 2500rpm its making more like 70hp not 130hp.

yeah and what I meant was the power band is narrow because there is no point using that last 1500 rpm.. power goes DOWN, markedly.

So you need to change gears at 6000, otherwise you lose.. the rest of that plot is a waste of paper. A tuned rb26 you can change pretty

much at redline, the drop off is so mild and only the last 400rpm.

sure it does 500hp from 5000 rpm ... but only for 1000 rpm of usable revs!

Quoting Mr.Alex

Hi Guys!

Thoght i'd share my big block evo experience with you.

Got the engine tuned and dynoed 2 months ago, been to the track for 2 days and the only thing I can say is that this is one crazy engine, all that tourque is just amazing on the track, pulls so hard after 3500rpms that i barely ever go below 4th gear.

i dont know if the scale on the dyno chart is correct cause the car is a beast after just 3500rpms, pulls just so hard i can hear my seats crack

Its a build from a local tuning shop here in Sweden, Autotech as said in the sheet :D They know their stuff, had time to to talk somewhat with em when a friend of mine mapped his Autronic controlled WRX STI on ethanol. Had this one in at the time.. gives you the creeps.... Got a couple of Evo's around here with 'big' hp's, many of them mapped at Autotech :bunny:

      I don't know if you can disassemble the thing and put it backwards for different ramp rates. They're both "2 ways" or both "1.5 ways" because well, 2 ways and 1.5 ways are the same 'thing' I do not know for sure, but I believe the 38420-RSS15-B5 is the 1 way, and 38420-RSS20-B5 is the two way. In other words, I predict Nissan considers this: to be a 1.5 way. No idea what actually happens when it arrives/you disassemble it. It would be an excellent question to ask Nismo directly! I somehow doubt you will get an answer though, I feel you would be the first person to document what you encounter when you open the box and the internet would be grateful.

      Well - they have arrived.  And they are easy on the eye to put it mildly... These only have three bolts - but for a start there is a key that fits with vacuum like precision..  And as you can see by my ruler, the interface is large..   I listened to a podcast on HP Academy about Dan (KiwiCNC) and I'm more than comfortable he knows what he is doing. R35 Bearing assembly should arrive later today so can mock that up for a look. Can't wait to get these on and get some brake pressure logging too. IMG_3860.MP4

      I would be very confident that they are the same parts (the 2 different SKUs). It seems very clear that you can drop the cam in the 2-way opening, or in the other opening. If you arrange it in the other opening in the same way that you see any other 1-way diff, ie, with the flat of the cam up against the 1° side of the opening, then it would work as a 1-way. It can only spread the ramps when driving forwards - cannot spread the ramps on overrun. It would then appear obvious that if you put the cam into the opening "backwards", that you would get the angled flats of the cam working onto the "points" of the 1° side of the opening, which would give you ramp spread in both loading directions. I do wonder if the forward direction of the 1.5-way config is equivalent to the forward direction of the 2-way, seeing as the cams are flipped and the angled surfaces on those would need to be the same on each side - AND - clearly when installed in either the 2-way or 1-1ay configuration they are not intended to work exactly the same (the ramp angles on the 2-way are 10° different between forward and backward, and the ramp doesn't exist in the 1-way config). 'twere me, I think I would rather actually have a set of rings that offered the 2-way with two different sets of ramp angles, say the 55/45 of the existing design and maybe a 45/37.5 combo for a less aggressive effect), AND another set of rings with a dedicated 1.5-way opening and a dedicated 1-way opening. The 1.5-way opening would actually have the steeper angle on the overdrive side that causes it to be less pushy than the forward drive angle, like you see in many other diffs. But really - if this Nismo thing is thought out properly and all those surfaces work on each other the way that they need to, who am I to argue?
