Here is a 6266 on a 2.6 on what I assume is the same dyno. Notice it goes to 210km/h so scaling is different.

Assuming 8k limit, @135km/h its on full song at about 5200.

True ebough, if its 7.5 its more like 5k.

I'd be interested to hear what the scaling actually is. I've always liked the efr83s as my next turbo, so if he's let off at 7.5k ish and making that power on a 2.6 I'll be extremely impressed with it.

As with most things I don't think the dyno plot can explain the response of it, but I'm betting its miles better than dash 5s at circa 2 bar. The efr looks like it comes on very smoothly.

Going off what Brett has said. 22 psi was reached at 4300 RPM which on that graph is 105 km/h. It's making just on 300 kW at that point.

Jezzebelle stopped there because of the standard engine.

* Green line is as it was dropped off, Red line was the final result.

stock longblock, small cams and simple setup! this car is probably much more fun than a dynosheet can explain, hopefully Reaper is pleased with the outcome

2jz with twin 6258s -- slightly OT, but too cool not to share:

"Geoff, wanted to keep you in the loop. Re dyno'd the twin 6258 IWG car on E85. Got her to 32-33 psi and ended up with 922 whp and 790 tq at 4600 rpm !! This is a 8.5-1 engine with a stock head and 264 stock base circle cams. Wowzer…I attached the dyno chart with the C16 vs E85 max effort pulls.. So impressed really. Cant wait to fire my car up with 7163’s…Thank you

Eric"

at 4k $ the v-cam are far from ''small simple cams '' IMO :)

Its a type a vcam intake with a type b poncam exhaust so they are pretty small especially considering no porting or anything at all.

5th gear, 285/30/18 rsr's and standard 34 gtr diff ratios with the standard 6 speed

Can't have been 5th gear.

5th @8000rpm is 220. top of 4th is 168km/h. which matches plot exactly.

so full boost@115km/h is 5475rpm.

300kw @ 5000rpm

400kw @ 6000rpm

***ignore above.. bad maths***

whoops! they are, good pickup.. sorry i under calculated the tyre circumference.

using circumference 1973.55mm (https://www.mcgrefer.com/sizeinfo/2853018) for a 285/30/R18

speed peak of dyno of 169km/h in each gear:

3rd (1,685): 8500rpm.

4th: (1,312) 6650rpm

5th: (1.000) 5050rpm

it appears it was done in 3rd.. could an 8500rpm readline be correct?

that means spooling (10psi) around 4500 and full boost (27psi) at 5800rpm

No.

There is a graph from very early on in the tuning process. 10 psi at 4500?

    • A few small updates since the previous post and lessons. I decided to do a little interior light upgrade on the 110. I quite like the iilumo items, even if they're a bit of a premium over other brands. You'll also note the Stedi Fogs, that will go into the S15 fog lights as I needed to match the bulbs since I got the new ones earlier. I hope they fit as the body is quite a bit longer than your normal bulb.  Annoyingly, I managed to trip the fuse, which normally wouldn't be an issue until I located the fuse. I can't say I've ever come across this. I had lucked out that someone nearby had a spare, but oddly enough Toyota dealerships seem to keep this in stock. I ordered some to keep in my stash and as luck would have it, someone else nearby tripped the same fuse so I passed on the favour.  I also did a little service on the 110 ahead of some additional work coming up. It's been annoying that Goleby's stopped carrying this particular HKS filter for the 110, so now I need to keep them on order from Japan. I also took the opportunity to install a bash plate and number plate riser. The plate riser is such a cheap but nice fix to help really tidy up the car. I'm tempted to now also replace my headlights, on this car. Both items were from Project Aero.    I also needed to replace the rear tyres on the 110, and after trying to get it aligned learnt that I need to replace some bushes in the front end, so that's next.  Closing out this update with a nicer picture as always! 
    • Yeah mate, never miss it.
    • Any going to watch World Time Attack at SMSP this year?
    • Appreciate the correction on the "ground", that will make a huge difference to looking at this. That makes complete sense about AF70/AF71 which is what I had come down to being the issue, one of these. I'll have another look in the ignition wiring when I get a chance next week. I'll also make up a jumper wire for running that AF73 test.  ECU is fine, relay itself is fine, pump harness is fine and the pump itself is fine. I am going to upgrade the Walbro 255 anyway with a DW300 I have since I need to replace the fuel sender and I'm going to upgrade the FPR with my chasebays kit ready for new plenum/injectors/dbw, but I'll get this working first. That's why this is so frustrating.
