Power loss - turbo not building boost as before!

Again, there seems to be some timing pull correction on Cylinder 3, from 3000 to ~4700 rpm.

After setting the FULL dial down from 30 to 25 psi and the START from 4 to 3 psi, this correction disappeared BUT notice how the power output also decreased.

So this means it's still spraying too much up top?

When making adjustments best to make a single adjust, then log.
I'll have to check it tomorrow.

The car definitely ran better when I had the full spray dial set to 30 psi. I could feel the power back. I'll have to run some more logs though to be 100% sure, will see if I can do that tomorrow night as well (if bad weather doesn't get in the way)

but yeah looks like we're going in the right direction, just got to keep playing with the settings. The last run I'm not sure if it was that my turbo was already heat soaked and that's why it didn't spike at much as before. Will see....do you think I should keep the full spray at 30 psi? Or maybe lowering the start? Since it looks like it’s not spraying enough below 4700 rpm

Based on your comments, yes move it back to 30, Is 30 the highest setting?

no, 35 is the highest. But wouldn’t it be better to set it to my actual max boost so the atomization of the spray is better? I thought the smaller jet would’ve solved that issue but it appears that it’s still too much spray since the further out I set it to the more power I gain

could it have something to do with it spraying directly onto the map sensor?

Yes nozzle position could be affecting things and yes it is possible that this nozzle is still too large.
Yes we would like to use full pump power but if flow is to great won't do us any good.

I would get a 175cc jet with a checkvalve of course. The bung on your tube should be 1/8npt so jets from snow or devils own will work.

the AEM nozzle body has an internal check valve already, so I guess I’ll just get the jet from Snow Performance

Keep having no luck

I just discovered that AEM uses this special thread size on their nozzles/jets that nobody else uses on their inside(side that goes into the nozzle body)
Outer is indeed 1/8” NPT but inner measurement is 7/16-20 UNF - 2a
And I already checked and they don’t have 175cc jets 😑

so sounds like I’ll need to change the whole nozzle body as well, maybe go with snow performance or devil’s own

just hope that I have no issues using an injection kit from a different brand

You would need to buy jet and holder that has check valve built in. I have mixed parts between kits to get the flow that I want. Snow or DO use push to fit 1/4in holders and your AEM kit uses 1/4in tubing as well so you can just take off the whole AEM holder/jet and push on a Snow or DO solution. The Snow or DO jets will screw right into the 1/8NPT bung on your turbo pipe.

AEM, SNOW and Devils are much more similar than they are different and systems really are very simple. Pretty much the only unique part is the controller and even they are very similar in operation. They all use the same pump. There is very little that makes them different, pretty much just an adjustable spray system.

When dialing these things in we have the following things we can adjust to get it just right on your single nozzle setup.

1. Jet size
2. Jet placement
3. Start spray
4. Max spray (this is the progressive part, set it low and it goes to full spray almost right away, set it some setting past your actual max boost and you can keep a jet from ever getting to full power.
5. The mix (we can adjust the ratio of Methanol to Water to further tune if needed)

Would like to see a T7 log with your current settings and then with MAX 35.

ok great, then I will have to get the jet, the check valve and a 90 degree elbow adapter, I had to use one for my current setup since I didn't have enough space to run the nozzle body straight (was hitting the transmission), I already saw the 175cc jet and the elbow adapter by SNOW but I don't know which check valve to get.

Would like to see a T7 log with your current settings and then with MAX 35.

yes, will see if I can get those logs tonight, I stopped at T6 because I was already seeing some timing pull correction.

Well, if you mount the solenoid very close to the jet then no. The reason it needs to be close when there is no check valve is that there will be "mix" in the length of tubing between nozzle and solenoid that can get pulled in when you are under vacuum. The longer the distance the more fluid.
Snow or DO sells an in-line, push to connect, check valve. I have used both. Mount in line nice and close to nozzle. Or buy a separate checkvalve.

Ok thanks. Got one more question, and this might be a dumb one but...can I attach the elbow adapter directly to the Snow check valve instead of the fitting it comes with?
Reason is I’m getting this 90 degree elbow adapter which is 1/8 npt male to 1/8 npt female:
https://www.summitracing.com/parts/vpe-11340
So I was thinking since the snow check valve is 1/8 npt as well I could just attach it directly
Anyways, that’s the way I had it with the AEM nozzle body attached to the elbow adapter then the jet on the other end

so going by the numbers, looks like I made the most power when I had the full dial at 35 psi, even though still never got to match max requested boost (1540 mbar)

what's more interesting is..I was able to hit more boost with T6 than T7. :unsure:
So is this one of those situations where “less is more”?

Ok thanks. Got one more question, and this might be a dumb one but...can I attach the elbow adapter directly to the Snow check valve instead of the fitting it comes with?
Reason is I’m getting this 90 degree elbow adapter which is 1/8 npt male to 1/8 npt female:
https://www.summitracing.com/parts/vpe-11340
So I was thinking since the snow check valve is 1/8 npt as well I could just attach it directly
Anyways, that’s the way I had it with the AEM nozzle body attached to the elbow adapter then the jet on the other end

Yes, looks like the Snow is 1/8NPT female so should be able to go direct.

Quick question, what are you using as a measure of power?

Quick question, what are you using as a measure of power?

I was just reading the logs, going by specified vs actual boost, if you go back to my previous logs, even when I had the 500cc jet on, I’ve always reached more peak boost (and sustained) with T6 than T7, it’s like the ecu pulls back, now I did speak to someone from Revo and they said it’s unlikely anyone can have timing higher than 6 unless they’re running some quality race fuel

TIMING 0 (LESS ADVANCE) – 9 (MORE ADVANCE)
This should be monitored and set on a vehicle by vehicle basis.

Vehicle should be setup to see no more than 3? correction under sustained load

Timing 0 is equivalent to stock timing

We recommend running timing 0-3 in hotter conditions or with fuel quality equivalent to 95ron

We recommend running timing 3-6 in normal conditions for fuel quality equivalent to 98/99ron

Settings 6-9 are to be used on vehicles in optimal conditions or running racefuel or WMI

NOTE: We do not recommend leaving customers car setup specifically for racefuel or WMI unless they can guarantee they will always use the same fuel.

Running too much timing will result in audible knock (pinging/pinking), you will also see overall timing advance dropping off at higher rpm in comparison to running lower settings as well as lambda going rich if the ECU goes into knock protection.

As an overview:

99 Ron - Timing 3-6

97 Ron - Timing 3-4

95 Ron - Timing 0-3

NOTE: It is unlikely you can use timing higher than 6 unless using a quality Race Fuel.

Ok, just keep in mind that boost is only air that has NOT gone through the system so it is not necessarily a measure of power. We would want to be on a dyno to really know if we are making more or less power. You could have more boost but less timing advance and make less power and you could conversely have less boost more timing advance and make more power. Boost and timing advance are 2 of the major ways to turn up the power. Methanol has an octane rating of 116 so in addition to cooling you are getting some small amount of race fuel effect.

Ok lets work on T6 first. If T7 (is this the top setting?) puts you out of 93oct requirements then we can hold off as we would configure the system differently for that. I would like to know what the fuel requirements are for T6, T7 etc. I don't know what values the T settings represent, I thought all of what you were working with was 93oct based tune.

On my K04 setup I ran 91 in tank, a Snow system with 2 nozzles (one off intercooler and one in a throttle body plate), both were 252cc nozzles and I ran a 100oct race tune daily for 4 years. Dynoed 336/335, it had power from bottom to the top.

Just an FYI, we can use your system to both cool and fuel if we venture into a part of your REVO setup that requires higher octane fuel. Spraying farther away provides cooling, spraying after throttle body ( requires a plate and puts you right on the manifold) can supply fueling to allow you to run tunes that were intended for race fuel. Full evap right after intercooler cools and condenses the air and spraying in the manifold (from the plate) allows actual droplets go to the cylinders where it wil act more as a fuel as it will not fully evap.

Note - Revo notes are not taking into account your WM system. Timing loss of 0-3 would be a range you would expect without WM and would vary mostly on the weather, amount of timing pull directly related to how hot the air is outside. With WM we can cool things waaay back down much cooler than what just a big intercooler can do.
