Very first pull on the dyno, well once i changed to a 7 bar map sensor. I used 16psi springs in my twin scroll manifold. But for some reason 22 is my low boost. Its a major job to get the wastegates off as i have plumbed them in and very little room to work around.

On this run i backed off at 6400rpm

Overlay shows my previous best with -7 copy twins.

Both on E72, both have same tyres etc etc. the e72 in the tank atm is 6 months old

How about some rpm scale love there Jez instead of road speed?

All looks promising so far - I bet you're happy!

I can try for u stevo but its only roller speed and i can input what rpm at a certain Speed if that makes sense. I mainly use it as a reference. Worst part is it doesnt save each time the dyno is on so i cant do comparo's on different days with rpm.

Gotta be happy with that jez

Very. Cant wait to push some timing into it. Think i might stop at 420ish kw. As stock engine and cams

Yeah that makes sense, fair enough.

When's more tuning going to happen?

Putting fresh fuel in for that?

Would be great for someone to do back to back testing on a range of these things. Eg 5557, 6262, 6466 etc all on the same engine, same dyno

I think I put a link in here a while back from some guys who did just that, albeit on a 3.4L jz

What twin scroll manifold and gate/s are you using for the precision Jez?

6 boost manifold twin tial 38mm gates. Custom dump and plumb back piping.

Stevo hoping to get the rest tuned on e70 sunday. See what boost i need for 420kw. Then wsid for a 1/4 mile run to see if she holds together

    • This. A 3d wheel alignment is like $120...just take it to the shop. Since theres probably multiple adjustments that need to be made after changing something. Mine has front/rear lower arms, traction rods, tension rods, camber arms, toe arms, front upper arms, hicas kit, sway bars and coilovers. I measure from the edge of the bolt holes on the originals and set the same length on all the adjustable stuff to dial it as close as I could to OEM. Took it straight for alignment; it didnt feel right at all...after alignment, it feels perfect. Similarly i've just changed the springs on another car; and I still needed multiple adjustments to bring it back in spec.
    • A full Veilside kitted JZA80 Supra in Meriken park in Kobe city a few weeks back
    • Its a well known brand in New Zealand; its a rebrand of the Rhino RAV3.  I don't know what the wiring difference *is* between the rev.1 (installed about 15 years ago) and rev.2; but as you say I would think its reasonable that it uses the same immobiliser relay circuits. I had a look but couldnt see a similar harness; but didnt move things around since I didnt want to mess with it   It was one of AVS well known Authorised Installers; I spoke to AVS themselves about it but theyre unsure hence seeking advice more so from the skyline community who are more familiar with the actual car and its wiring. Im in Auckland; but the installer is on the other side of the city so hes very reluctant to come back to even look at it to confirm something isnt connected into the wrong wire.  I dont want to drop the name since they *did* do a really good job for the most part. Everything is very tidy and he fully replaced all the alarm wiring, all the sensors, the wiring to the door motors, installed a switch which was never installed in the first place...really happy with the alarm install itself..just not this one issue. We all make mistakes, if it is the alarm, I just want my fuel pump getting proper switched, fused, power as it was; without having to shell out for an auto electrician to switch a wire and tell me it was the alarm. 
    • Even with the piston at TDC there was room for it to drop, but I don't think it can drop fully into the cylinder, the problem you have is that you need something pushing against the valve to hold it up so you have enough room to put the new stem seal on and the spring etc.  I used compressed air only because putting rope in the cylinder seemed a bit risky to me, I know people have done it countless times before like this. Overall it's a pain in the ass job. Honestly you'd probably be better off taking the head off because the risk of dropping something in the engine and the finicky-ness of it all is very stressful. If you are going to attempt it though i 10000% recommend a 36050 valve spring/keeper tool. I had both the traditional lever type and after doing 1 cylinder it was absolute pain to get those valve keepers in place, even with 2 people. That 36050 is amazing, you do have to push hard to get them in place but it works perfectly almost every time. Back to my actual issue I think my engine is just tired and old and the rings have gone bad. The comp numbers (cold, no oil) were: Cyl 1 -129psi Cyl 2 - 133psi Cyl 3 - 138psi Cyl 4 - 137psi Cyl 5 - 157psi Cyl 6 - 142psi   Cylinder 5 and 6 having the most carbon on them.
    • Who did you have do the installation? I actually know someone who is VERY familiar with the AVS gear. The main point of contact though would be your installer.   Where are you based in NZ?
