Steven,

Those fuel pressures look much better! Can't wait to see that Garrett make some boost! :sunglasses:


It's a spin-off company of VTT.
Hey Jake,

While VTT/Tony has been a huge asset with regard to set up/resources (good to have a friend in the business) Tony is not involved with any day-to-day operations, building, testing, promotions, sales, shipping, emails, etc. :)

N54 actuator on all of them as the N55 actuator is garbage, prone to failure and not sold by themselves. The N54 actuators hold vacuum better, are much more precise, and can be replaced very inexpensively (~$25). Every N55 turbo will come with an actuator set up and ready to install.

nice result Steve. Thanks for sharing the dyno graph and more importantly, log!

Just as another data point, I got 491 whp, 501 wtq, at ~21 psi with similar modifications (log: https://datazap.me/u/houtan/sbrach-v466-v28-dyno-load-run-6-7-8?log=0&data=4-18-24). Link to dyno graph is here: https://www.1addicts.com/forums/showthread.php?t=1405434. I believe the main difference between our cars is, I am stock flywheel, charge pipe meth, and that dyno was on commanded wgdc tune.

The speed at which you get work done at home is impressive. I think it took me about a week to get my stock turbo out! Looking forward to hearing how the new turbo performs.

Thanks houtan. You were at sea level vs my 1300ft, correct? What exhaust? I don't think the magnaflow on my car flows very well.

Yeah. Per Wikipedia we are at 52’.

For the exhaust, I just removed the back half of the stock piping. I wanted bigger piping with the least amount of bends so I ended up with what you see below. I really like the way it turned out.

I had a muffler shop order a 2x2.25” into 3.5” y and a 3.5” muffler. The muffler is a magnaflow. I think magnaflow only had one muffler at 3.5” that fit well. The sound is a little deeper than I like (but magnaflow's have more of a deep tone so it probably sounds similar to your car) and there is a little drone from around 1-2k, but it’s not that bad and I am old haha. I will probably go back one day and have a couple of resonators installed. Also, one really odd thing that happened is my turbo whine through the exhaust is completely gone, which sucks because I love that sound.

Most importantly, it definitely freed up a few ponies, which was the main objective. Not sure if it will get you anything over your current set up though.

Ahh cool, did not know that. So who's the owner? Looked like the same exact work bench that the product photos were taken on :)

The Mini Cooper S pneumatic actuators are a direct fit replacement for N55 actuators and go for around $30. FWIW.

There were a few people involved in getting PFS off the ground and all of them are part owners with different roles as agreed upon (obviously myself included). If you're just asking if Tony is one of those owners/investors, yes, however he has no active role within the company. I do consider him both a friend as well as a valuable resource though, and we regularly talk about new ideas/testing/changing platform needs. Not sure what bench you're talking about -could be an old photo before we sorted out who was doing what and it might have been his bench. Any new shots I take are either in the workshop or in the photobooth (customer car shots aside). Feel free to shoot me an email if I can ever help you with anything fueling related.

Time for an update. I know its been a while, January ended up being super busy for me at work. I've been in CT for most of the time since the holidays. The kit fits great, installs like stock including the lines which obviously had to be changed to support the Garrett CHRA. Had some issues with the WG actuation which had me chasing my tail looking for a boost leak that wasn't there. Running 29psi to redline now and it feels great. Hope to get on the dyno within the next week or so. More info to come once I finish dialing in the tune and get dyno numbers. Sneak peak for now;

Thanks for the update Steve. That log looks great; especially post shift boost! Is there something you figured out to keep the boost on target right after shift?

Looking forward to your Dyno results. But based on the log, she must be movin’!

How has the car been with the new flywheel? Are the phantom misfires completely gone? That is the next modification I need to do.
