Per your graph, it appears you are tapering to 18.5 at redline?

[1cleann55]

I set it to 16.5.. on csv you can see somewhere of 17psi closer to redline though.

[1cleann55]

Actually im wrong its 15psi at redline and 17 psi around 6500 rpm area

[1cleann55]

Can someone answer this question. If you have a turbo rated for x amount of boost but can only run the x amount of boost safely with higher octane can you still force the turbo to run that amount of boost even though you don't have the fuel? I would assume yes right.

You can set the targets, yes. This is what pure did when testing boost on low octane/pump fuel. The car does not like it and certainly will not hold the boost long at all and will taper way below its targets. Timing gets jacked up too

It would hold the boost you'll just be running like crap (lean). But youre still making the amount of boost youre telling the car to make correct. I was showing the logs to a friend who wants a stage 1 also and he states the vargas flows better no matter what because even if you add high octane to pure log it'll make the same psi but obviously timing will improve and you wont blow up basically. Correct or wrong?

Wrong.

The tag is for us to indentify the turbo by invoice number. Feel free to remove it and save it, if you are still under warranty. They are very easy to remove

Can you post the csv? From the graph it looks to me more like 16 psi at 6k and 15 psi at 7k.

[1cleann55]

Seems I forgot to install the screw on the crank case line on my intake... whoops idk if this may case a leak or have any effect on the turbo but I'll probably do some more logs to find out

[iuhutch]

Your previous logs looked great so I doubt any difference on performance but good catch before it ended in something bad...

That should only affect AFR's as it may have been running a little leaner.

Here is another graph from same competitor running decent octane and timing on my car:


Added the csv corresponding to screenshot above:
http://users.telenet.be/darkhold/pure_max_boost.csv

[1cleann55]

I left my house and downloaded the wrong file on my phone and now i cant upload the file so heres a screenshot on my phone of the boost and target rpm. These were lower targets. I'll post the 19psi csv when i get home

[JETmn]

Very interesting. Limited data so far, so take it with a grain of salt but boost at 6500 is 10psi on the stock turbo, 15psi from the 1st log 1cleann55 posted (latest one is lower) for the VTT stg 1 and 17psi for the Pure stg 1 v2 that Darkhold posted.

This is just 1 data set so it isn't extremely reliable, but it is all we have right now. All cars were at or near FBO.

Columns i screenshotted are rpm ecu psi target and boost maybe when i downloaded it to my phone something got messed up idk but this isnt the matching one to the graph above i downloaded the wrong one. Also darkholds log was done in 5th gear you'll obviously get different boost readings

[PeterPure]

I think your 4th gear would match my 5th gear. Slightly longer gear for you but that doesnt matter.

[JETmn]

1clean that only shows to 2300 rpm. Can you post it to datazap so we can see the whole thing? What boost are you seeing at 6500rpm?

He will do a 4th gear log later tonight.

i downloaded the wrong file from home these arent the ones that match the graph log up above

[1cleann55]

Literally just finished 4th gear log for comparison with darkhold. I stop at 6k rpm because I was doing 125ishmph THAT BOOST THOUGH

[1cleann55]

Heres a quick pic im still not home
