A lot of stock exhausts are too restrictive for even a software flash on many turbocharged cars let alone cars with upgraded turbos. Get a cat-back (even a downpipe if need be) and never look back.

 

Posting for Sharif:

So I got bored on Sunday and converted over to E85. Just did some quick adjustments of fueling to get me going, but OMG it's much more responsive on E85. I will be on the dyno this week with it again for the big stock block numbers. I really want to see 450-500whp on our Dyno Dynamics. I will definately have the video camera rolling for those pulls.

Also just heard from JRZ today that the suspension bits are back from the anodized which means assembly and shipping is just around the corner.

 

The car is coming along great. Whens it going back to the track?

 

I just ordered a muffler delete exhaust for my new '11 STI sedan from a company in Washington. Only $370 including custom powder-coated tips, and entirely made in USA. They're just getting started in the Subaru business so they're selling things really cheap IMHO. For that price, if I don't like it, who cares? The stock exhaust on my car is WAY too quiet.

I'm still on the fence about suspension changes. They made a HUGE improvement in the '11 STI versus previous years in terms of the entire suspension.

I'm still trying to figure out two things:
1. How do I turn off the hill start assist? I've been driving manuals for over 20 years and I don't need any help. The thing just ticks me off.
2. Why can't I set the car to always be in S# mode instead of defaulting to S?

I'm pretty happy with the car so far, but it needs a stage 1 tune and the new exhaust. Then we'll see what comes next.

 

This weekend.

Hoping to drop the STi's time more this round at Road Atlanta.

 

The cobb ap can change the settings of the S mode so it will remain in sport always. I'm not sure about the hill assist.

 

Sorry for the lack of updates. We have been completely consumed with customer projects that the STi has been neglected. Here is a picture of our new FP Dual 3inch exhaust. This baby sounds killer!



Thanks for looking!

Nice progress

 

Soundclip, please

 

Just wanted to chime in and say the car had some tuning last night performed. Sharif is going to chime in a bit later with the results, and dynograph with video. We apologize for the lack of updates. Our customer cars take #1 priority over our Project STi. We are currently working on over 50 customer project vehicles.

- Hopefully some more goodies along the way!

 

Hi everyone, it's been hectic to say the least. I wanted to thank all of you your interest and support of this project. The 11 of us that work at Forged are all hard core enthusiasts that live, breath and eat this stuff just like all of you. As such, I can get pretty addicted to working, tuning, and trying to do the best possible job for everyone. So bear with us as we're burning the midnight oil.

As Tray mentioned, I spent a couple hours last night finally getting a chance to tune the car on E85 at higher boost. The objective was to push to 30psi on the stock block, knowing our single pump DW pump would not make it that far. But I was pleasantly surprised at just how far it did make it and far exceeded what can be done with the traditional Walbro 255.

At the end of the tuning session with E85 fuel, I acheived 471whp@26psi peak boost pressure on our Dyno Dyanamics AWD Dyno (no BS inflation added) before running out of fuel. For reference, our project car did a 197whp baseline. The turbo absolutely JUMPED to life after about 24psi, and I can tell it's begging for much much more. Full boost at 4750rpm isn't too shabby either for a big PTE 6765 turbocharger. Before our stroker engine goes in, I'll do one more tuning session with our big flow fuel system before yanking out this engine.

Enjoy the pics from last night, and the videos are being edited as we speak.

 

Great results! That thing must be a blast to drive with awd.

 

Here is the sought after AMS Intake Manifold. Let me remind you this is their Prototype. This is not a final product. The final product will be made from cast and will look much different. Forged Performance is honored to be given the opportunity to test the manifold. We will be performing a back to back dyno session. We will let everyone know the performance, and feedback of the AMS prototype.





Install and Testing coming soon!

Thanks for looking!

Got a few more items in the mail today that I'd like to share. Tomei sent us a few goodies that are going to be perfect for our Engine Build. We ordered the Tomei Timing belt, Belt guide, Baffle stiffner, and 270/270 Camshafts. The quality of each of the Tomei parts are second to none. We look forward to installing these items, and putting the camshafts to test.




The Tomei Kevlar Timing belt, and Belt guide. The timing belt is super tough and is claimed to be 4x the strength of OEM without sacrificing durability. We paired the timing belt with Tomei's belt guide. The Belt guide is a straight cut of aluminum with an extended length to securely apply more tension to the timing belt. This product comes in handy when immediate changes in torque are experienced by the engine, eliminating belt whip.



Tomei's highly experienced engineers developed an engine baffle stiffener to help prevent bearing failure, and help regulate the oil supply. During the R&D Tomei found one of the main causes of engine problems on the EJ20/25 are the bearings. The majority of the cases were caused by lack of motor oil in the oil pan (sump) and passages. They also found that the lack of rigidity in the crank case is also another problem facing this engine design. Under extensive research, Tomei created the baffle stiffener which helps strengthen the left and right side of the crankcase to help provide the added support with its dual structural design. The rubber baffle design greatly aids the regulation of the oil supply. This gives added control to reduce blowby for EJ20/25 owners who use their cars for high performance driving.




The most exciting parts that arrived were the Tomei PROCAMS. We decided to go with Tomei's PROCAM 270 Intake, & 270 Exhaust. We felt this was the best bet for our large turbo application. The specs on the camshafts are quite impressive. The Intake side has 11.0mm lift, and the exhaust side has a lift of 10.8mm. With that lift we know it will make an significant improvement to our 2011 STi build. Not only do we hope to achieve more power with the camshafts but improve the powerband. We look forward to performing a dyno test in the weeks to come.

Thanks for looking!

You folks do such amazing work...looks beautiful!
