That looks like some pretty EPIC spool.

How does it feel to drive?

It brings a smile to my face every time. The ball bearing turbo was a good call. I hit full boost 20psi at around 3500 it takes off like a rocket and it holds it all the way to redline.

The 20g-xtr is a great match for that STI tranny. The gear ratios are perfect. And you have a perfect setup to go flex fuel as well, which will really push you back in the seat. Those are strong numbers on a Mustang dyno!

Wow that spools surprisingly quick. XTR's are great!

I wonder if he would need slightly larger injectors to go flex fuel on that beefy of a setup. Maybe not tho

@GK1707 What duty cycle are your injectors @ under full boost on pump gas?

That I haven't actually logged (I need to take a WOT log some time soon so I will post it when I do).

Based on Fuel Injector Clinic and Injector Dynamics fuel calculators this setup with these injectors on flex would be around 75-85% IDC (I'll need to take an actual log to be certain how much duty I'm running) but that seems a bit much for my liking.

So I've been certain 1300 or 1700s would be safer for flex. When it comes to that point I may just bump up in turbo size also and move to an ELH.

Yeah that 100% makes sense. I am switching from 1050s to 1300s when going flex fuel on a 2.1 stroker.

That has always been one of my favorites for a daily street driven setup. 20g xtr, id1k's and ewg. I was easy to make a safe but very quick car in the 400hp/400tq area. and pulled great.

Nice set up

Yeah having more headroom would be much better. Im sure I would have had no issues with IDC tuning flex fuel on these ID1050x (could have probably turned it up to 23-24PSI on E85) but I figured I'd save the flex tune for when I decide to go bigger turbo, injector and make some other upgrades.

Id for sure recommend this setup for anyone dailying their STi. Awesome usable power throughout the rpm band. On flex fuel, this setup is absolutely capable of 400/400... probably more on a dynojet.

I did that. When I bumped my injectors to 1300 for flex fuel, I also went to a Dom 1.5xtr. Just had ELH headers installed, as my UELs had cracked. Very pleased with the results overall.
