Boost or Intake leak = overboosting turbo (correct psi by the time it got to the engine) = overheated turbo = warped / cracked exhaust manifold. My day was over by midday.

No worries about the helmet, never put blocks in place that stop people from getting out onto the track. We've got future track day participants to take care of!

Give it till the 22nd for results... At the moment its happy building solid base, im happy it hasnt gone spastic high and then everyone dumps within 24hours.

Am sad it's doing what it's doing...having bought a house I have no significant monies to throw at it at the moment

Only problem with E85 is that it allows you to push so hard on the tune you will break the next thing up the chain as it will never ping.

This ain't so good if you have metal head gaskets, head studs, stronger pistons, rods, crank because when they aren't the weakest point you end up Gregging it™

98 isn't a bad idea as it stops you from going too insane, its a built in safety measure of sorts to make sure the rest of your setup is actually going well. E85 is like fuel-steroids. You can get the 'right' power on 98 in a Skyline at least to the point where everything else starts to become a limitation. You may not get forum and instagram #efame but you will be able to have fun with the vehicle and have a modicum of reliability and do more than hardpark it and fap over a dyno sheet if you go full retard with timing. (or full advance on timing, really)

If you're shifting the performance of your engine into territory that breaks things then that's yours or your tuner's fault, not E85. E85 can take more timing than 98 but that doesn't mean you have to knife edge the tune any more than 98.

This is why you start with E85 and aim for the power figure you have in mind using that fuel. Don't use it as a tool to get another 50rwkw out of an already traction-and-parts-breaking setup, use it to help a smaller turbo give you the same top end power with a fatter midrange, significantly better response, cooler engine temps and smoother idle. Then switching to E85 will be safer than 98. You also don't have to drive the car as hard to get good performance out of it.

Thats the thing, not many people are splitting blocks with 400kw, but if you run as much timing as I was running (which was really wild, looking back) the car will "run fine" and E85 will not give you any indication you are near a knife edge at all.

It will continue to make power and continue to take timing and continue to respond "well" even though you're well into imminent death zone. Unlike 98 which will ping, E85 will give you no such warning.

I now run E85 with basically the same timing (2 deg) as 98. That said my 98 tune is more conservative than most people's run in tunes, so E85 is essentially in there for safety only.

You can do crazy things with E85 (like say, add 15 deg of timing!) but don't. It's best not to make your first point of failure the engine block.
I since compared many maps with many other cars at the Dyno making similar power and ones making much much more.

I now get unreasonably worried when I see -9 setups on GTRs making 320kw on 98 and 390kw on E85, people making 370kw on -5's  and 450 on E85 and think oh damn there's gonna be some issues there soon.

I don't understand this - what do you think split your block if not too much power or poor structural integrity? Pre-ignition? Not all blocks are the same and the N1 was created for a reason. Hamish did a bottom end with ~300rwkw.

People break engines all the time on 98 without warning signs. It's no safer. For reasons I suggested before, E85 is much safer when shooting for the same power level. I'd even wager it's still safer with a bit more power than the 98 tune.

I feel like you're saying 98 is safer because it will detonate before you get to unsafe power levels - if that is the point then it's moot when you can just not aim for the skies and be careful about your power levels.

We're saying much the same thing I think

Did he do a bottom end by cracking the bores themselves? If so I was unaware. I would wager the amount of timing is was advanced I was basically compressing an explosion. It is possible that the 34 block is just weaker (somehow, it doesnt look to be any different), but there's plenty of people making much more than me out there humming along just fine.

Should the tuner in this case have said "Dude the timing numbers here are way beyond literally any car Ive ever tuned?" instead of "Gee this engine really likes timing"? Yeah probably. I'd wager that won't be said again and the magic E85 envelope won't be pushed that hard again.

I'm not saying E85 isn't safer than 98, it is.
On the same turbo making the same power the E85 is much safer.

Whether going a larger turbo making 300kw on 98 vs a smaller turbo on E85 I am on the fence about. It's really pretty hard/impossible to know.

Being safe and sensible is the best idea. E85 can let you press way further on the same hardware and it is "Safe" in the sense it gives you no indication things are about to go south quickly. You can run 10+deg or more timing and get 70 "Free" KW!

You simply can't push that hard on 98 because the fuel itself is going to stop you, so you can back off at that point (i.e dont run it on a knife edge) and enjoy the car. There is no such thing as a truly free lunch. Run a few degrees of timing over your 98 but don't look a gift horse in the mouth :P

Your own car's performance at 270kw is a good testament to keeping it simple.

If I could refund everything I'd ever done I'd want a LS in my car instead. Make the magic 270-300kw as lazily as possible!

This isn't a difficult decision. Smaller turbo with E85. The turbo isn't being driven any harder to make the same power, intake temps are therefore the same and less. My 275kw on E85 is the same boost (15psi) as the 252kw tune on 98. Same tuner, same degree of safety in both tunes. And that's just the top end power difference, which is admittedly choked by the small comp housing. Midrange picked up a full 40rwkw, same boost, just more timing. At these power levels the components have been safe for 5+ years of daily stick giving. It's about picking an appropriate power level for your components and finding the safest and most beneficial way of getting there. That is without question E85 and a smaller turbo! Open your engine or aim for the skies and you're asking for it. I think you know this now though, given your retrospective desire for an LS conversion...which I still think could be negated by the tried and true highflowed RB25.

If you continue to tune an RB beyond what the known limits of certain parts are, just because E85 is allowing it to keep going no problem... then you shouldn't be touching a tune file in the first place.

Are you building this car for your great grandchildren?

Seems like you havent had a finished car since 1908

    • Per Mark Roberts of Sonictune: Mark Robert Author At this time, no. No ETA either 2016-17 models. You will be able to purchase and install a 2018.5+ TCU though   TCU purchasing and pricing info! As we near the release of TCU tuning, I am going to answer some questions I get asked often.   What do I need for TCU tuning? At this time, you will need a 2018.5+ TCU to be able to tune. If you have a 2016-to early 2018, you will need to replace your TCU with the newer version. One good way to know if your TCU is good is if you have auto upshift in manual mode in 1st gear around 6500 rpms. If your manual 1st gear goes to 7k rpm and will hit the rev limiter unless you shift, you have the older TCU.   Why do I need to buy another ecu license/phone flash if I already have it on my ECU tune? The TCU is its own computer module. It is completely separate from the ECU. Because of this, you will be required to purchase a TCU license and, if your tuner has it, the phone flash license required to tune it via phone/bluetooth.   Do I need TCU tuning? TCU tuning is NOT required. However, the faster your setup, the more it will assist in track and dragy time consistency.   If I’m ECU tuned by (tuner A) can I get my TCU tuned by (Tuner ? Yes, since it’s a different module and a completely separate flash, you can have two different tuners. However, it is highly recommend that you have both tuned by the same tuner. For me, my TCU tuning will directly complement my ECU tuning style and features and running my ECU and another TCU or vice versa MIGHT cause some issues. At this time and for the foreseeable future, I will only be tuning my current ECU tuned customers TCUs.     I have a SYVECS AWD controller. Do I still need it? Yes! The AWD controllers main job is to control your AWD system. However, with TCU tuning, you will no longer need the auto-shift function as that will be done through the TCU. The AWD controller will still be very beneficial for racers looking to maximize traction on the launch.     Shift schedule changes: holding gears longer at lower pedal input as well as max shift rpm changes. Please note, the new ECU race rom coming out will address 90% of the shitty drivability issues these cars have through custom maps from myself and Racebox—as well as others I am sure.   Increase shift speeds: as seen in the videos I’ve been posting, the TCU shifts much faster once tuned.   Increased shift pressures: as also seen in the videos, much firmer full throttle shifts.

    • The fancy pants red shock tower brace is finally incoming from MX5 Mania, getting it shipped from 'Merica has been a long and problematic process, and GWR, the 'Merican supplier will not ship directly to consumers outside of the US, Mania basically had to order a heap of them, the colour choice was silver, or red, and we all know anything red adds 5 killerwasps of dynotorques..... Whilst it does fit over a 2.5, and I've seen a few photos and videos of it being installed and fitting, google also says it might get real close to the FAB9 intake front runner, people in the US says it does fit with the FAB9 intake, except for one person who said it slightly touched.......so there is that.....LOL..... As it seems that I am the first in AU to have this combination of parts there's no local knowledge about fitment, so I'm just a willing guinea pig in this endeavour, I'll cross my fingers and toes and hope for the best In other news, I ordered stuff from China  on the same day I ordered the 23° silicone bend from Victoria, the stuff from China arrived a day ago, the 23° silicone bend is still travelling around Australia thanks to Australia Post, and "may" be here next week
    • Very good news...I contacted Racebox about it last night. My car is a 2016 so remains to be seen if it is compatible, requires a TCU swap, or is impossible.
    • What ECU are you running? This is probably the biggest question. If it's a PowerFC, I'd probably change the ECU and get something newer that will handle the injectors in a nicer way.
