The second etuner helped me run down some of the issues but i ran out of time before dyno day to. Yup dyno day is tomorrow. I have it a shop now getting sorted before it gets put on the dyno. Here's to hoping it's all sorted by tomorrow, lol.
Looking forward to results!

What were the issues, if you dont mind me asking?

So the end all be all was the car put down 350 on 93. Unfortunately, the shop did not give me a print out and I was not allowed to be in the dyno room. I was also told that this particular dyno is a heart breaker in that its a pretty low reading dyno.

Here are a list of items the shop repaired before the dyno and would be the reason the first etuner had a lot of challenges etuning the car.

1. LPFP was replaced with deatschwerks dw300
2. Header had a crack in it***8230; I had an accident couple years ago where I bottomed out on a railroad track at 60 mph. Apparently it cracked welds on the manifold pipe where it connected to the flange
3. I-PIPE had a hole in it
4. Rear o2 sensor electrical wire was broken.
5. And of course there were intake track leaks.

Short story, when your etuner tells you there is something wrong or you have a leak, take it to someone with more experience than you to get it fixed. Sure would have saved us both a lot of frustration.


My next round will be flex fuel and maybe CAMs if they ever get released.

ah that's a bummer you had all those issues. at leas they're not problems now though, right? have you had the chance to do any road dyno?

No, unfortunately the road I used to do my VD runs on has now been developed with houses and kids, too dangerous to do runs now. So... I can’t really compare them any more.

Going back under the knife with DRP and JR for a Flex Fuel tune with Cobb FF kit and Nostrum HPFP in the beginning of April... looking for a full send, lol!

Maybe a built block or FA24 swap in the future after we beat on this for a bit.

The new tune laid down a dependable 411 on FF! Car feels great! I’m looking forward to getting to the track soon!

Sounds solid, but still no dyno graph?

I'd have loved to simply seen VD from last tune to now. Data is data even if you couldn't directly compare with the earlier pulls.

I second this, and i find VD both extremely accurate and precise.

Nice dyno graph! That intake really opens up the top end. With a GSC valve train upgrade you can spin that engine a little more.

The HP line is still climbing! The torque curve didn’t flatten either but that could be the way the tuner tuned it. Or could be a trade off with a very high flowing intake manifold since even the BRZ manifold doesn’t really provide any low to mid range torque gain, just more top end power.

Without boost and timing knowledge, you don't really know. You can essentially sandbag a curve using those two making the top seem much stronger than it would have otherwise been.

I suspect the increasing curve is in the tune and done to keep rods from ejecting the block.

^This --- not built block. Definitely do not want to meet uncle Rodney im guessing lol Solid power for stock block tho

Yup this setup is capable of so much more if I had a built block...

Waiting to see what built blocks become available for the 2.4 before I make any changes down there.

The car definitely screams and could certainly use some head work to spin it out a bit more.

most all tuners seem to be comfortable with 330-350wtq on ethanol and a stock block. that's pretty RPM independent. if you run your 330-350lb/ft out to 7200 rpm you would pick up another 40~60hp up top. and that'd be about the realistic limit of your turbo. you'd want a larger turbo to take advantage of the built block, and a significantly larger one yet to take advantage of headwork.

but you are going to want to use that secondary injection and more ethanol.
with that manifold the shower injection acts as a secondary stage of intercooling, increasing density right in the runner and port. especially if you use higher ethanol content fuel. that allows the same port to take in more air mass. it also takes the burden off your direct injection, so you don't have to run as high a direct injection pressure, and then the stock HPFP can live with ethanol. it all works hand in hand.

right now it looks like your tuner backed off the boost a good bit as it built. looks like ~14psi tapering to what i expect is 21psi at 6800. since you're passing through different efficiency islands on the turbo and engine, and your EWGs change the balance pretty significantly when open, it takes a lot of effort to tune for constant torque, not constant boost. so i expect with further map revisions on the dyno your tuner could safely bring you quite a bit more in the midrange even as it sits.

that steamspeed turbo has a "3071R" compressor, which by my spreadsheets puts your dyno run about here on the compressor map:

i don't have a turbine map, but your EWGs make that not too big a deal. I'd say you're using it all well and just need more fuel and a few more RPM. otherwise you'll find yourself changing the entire setup.

I can appreciate the tuner keeping the block together... they’re in the business of making HP and keeping customers. It’s working for me, LoL.

The car has a Nostrum HPFP and Deatswerks LPFP. I have not pulled logs yet but looks like the boost is peaking at 24psi according to the dashboard.

Sick build dude! My stock block just popped. I'm having Prime put in an iag stage 2 block and stx 71r gen 2. I really wish my motor would've lasted a bit longer to see the built 2.4 options!

Good to hear you're happy with the steamspeed - that's what Prime recommended for me

Thanks man!

Funny thing is, this turbo is one of the first ones they sold 5 years ago. The hot side was upgraded by steam speed free of charge when the came out with Gen2. This cartridge has seen nearly 40k miles of abuse and still going strong.

From experience, this turbo with IBR manifold rocks it.

Nice!! I'm going to run it with the stock manifold and verticooler from my current setup. I can't swing the extra $3k for the ibr manifold and front mount right now. I'll probably add those later down the line.
