Pure900 on Pump gas...

[JAWTB]

A few of my scattered thoughts in the format of questions for people who are smarter than me...
Back story: Im military, I move every 4 years, where I'm going doesnt have e85 readily available so im confined to pump for the duration of my tour in that area.
I want to future proof myself so I'm considering the pure900 over the pure800...

1. Will the turbo lag be drastically worse on the 900 vs. 800 on 93octane? If so would rolling anti-lag be a way to combat it? How bad for the turbo is the rolling anti-lag?
2. Since the 900is bigger and stronger wouldn't that also mean that its less likely to fail under more the same amount of boost?

Whenever I leave the area I would most likely be looking to upgrade to e85, but I don't think my goal will ever be over 1k whp, I'd like to think 650-750 is enough.
I am aware that the pure800 can do that, but can the pure900 do it more reliably, while still not sacrificing too much while utilizing pump gas?

I just got my Pure800 installed the other day w/ S58 injectors & tuned. On 93, it's making somewhere in the nature of low to mid 500s. Mine was street tuned & not dyno'd, so it's a "trust me bro" thing. Sports display shows somewhere in that ballpark, so that's what I'm going on.

What I will say is the driving dynamic of the car has completely changed. I'm sure some of it's the tune, and some of it's the larger turbine, but the spool up is day and night difference, much longer spool up, to the point where I miss how quick the OEM one kicks in.

If I were you, I'd find another owner in your area, someone who has one, and ask if you can do a ride along while they do a pull. If I had done this, I probably would have gone with a smaller Pure650 or Pure700. I lose traction w/ traction control on in 3 to 4 now (or was it 4/5? can't remember), which is new and something I wasn't prepared for, lol. I'm scared to disable traction control too. I don't think I'd personally recommend a bigger turbo than this for most people. It's a big change.

I'll summarize by saying: The Pure800 on 93 is scary on this car and it's an absolute weapon. I'm here to tell you mid 500s is a lot, it's more than enough for me, lol. I couldn't imagine an E tune with this car. Vod attached, (as I've been saying in the Supra discord), spot the timestamp where I pissed myself! Made me feel like a Mustang driver for a minute

What else do you have done?

What else do you have done?

AA DP w/ the GESI cat, FTP charge pipe, MSTv2 for the intake, the standard stuff. No intake manifold, no PI spacer, no flex fuel sensor, no upgraded fuel pumps.

The display can be easily manipulated to whatever you want it to show and it’s also not at the wheels as it’s based off Nm data. I can set mine to show 1000hp if I wanted.

100% - hence my take it with a grain of salt. Gotta find me a dyno sometime soon. Not that it really matters - it's got more than enough power for me.

pure900 isn't stronger. it just flows more air. that means more power at the same boost pressure.

the benefit on 93 octane is that octane limits come quick when a turbo is superheating air. on a bigger turbo, you can make the same power on less boost, which means less heat, which means more power when you're octane limited.

but it's all in the tune. you can get a map that makes stock power or one that makes 500+. some tunes target as much boost as possible as fast as possible, others target a flat progressive torque curve. it also depends on your fuel quality considering all 93octane fuel is not created equal.

also it shouldn't be significantly more laggy than a pure800 but definitely more laggy than stock. if you drive around in D where the car is shifting at 2000rpm, you'll never get into boost. S mode will be your friend to keep some pep in the car when driving around town, or just shift manually.

I have tracked with the pure 900 on pump and E mix with race fuel , the car does not feel laggy but you feel the boost more when it kicks in and when it does it keeps pulling so takes a bit getting used to and as for power with upgraded injectors as well as upgraded HPFP and LPFP this is what you should be roughly expecting

green = shit Canadian pump gas
Red = shit E50

so you might get a bit more but this is the result

Interesting. How does this work? I assumed one could poll PT-CAN for actual delivered torque and the display merely calculated HP from that data. But if you can fake out the display, that can't be how it works.

As an aside, I saw on your YT videos that your HP goes to 600 under WOT, is that accurate or no?

It goes off Nm that is being reported to the DME and can then be scaled however you want in the tuning software.

Reported Nm can also be manipulated depending on how you have torque tables set in the DME.

I tried to make mine pretty accurate although I think it's still off a bit. It hits 640+ at some points.

I'm on a turbo that's in the ballpark of pure 900.

#1 the pure 900 will sound better than the pure 800 if you're into T51 sounds.

#2 you can make mid to upper 500s reliably on pump gas. On 94 octane and 24PSI i'm making 591 whp and doing high 6s low 7s 60-130 mph with an MT. You'll be faster.

#3 once you introduce Ethanol you can reach your power objective on less boost, more reliably.

This being said. You should evaluate the following turbos before making a decision:

DAW 6769 - same price range and similar size to the pure 900. No T51R mod
DAW 6969 - Larger than the pure 900, capable of mid 900s to 1000whp. No T51R
Remnant Omega 65 - Similar capability to the DAW 6969 with the new housing. T51R mod. Comes with charge pipe and intake.

I have 9000 miles on my remnant. Plenty of track time and wot pulls with no issues.

On some fb groups I’ve heard people really complain about the quality of the remnant kit, lots of issues, so it kinda scared me away from it

I’ve had some inconveniences but no issues. Install on 6 port is very tight. Wg actuator arm needs some readjustment.

overall it’s been super reliable and I’m in a group with many other owners who’ve had no issues.

that being said, don’t buy something that you’re not sure about.

DAW has great options and I’ve heard good things about the pure 900 also
