    Stage 1's installed on first vehicle, ready to ship. Intro price $1299

    After some installation issues with the customer performing it themselves which lead to a no boost condition. I pulled it down and finished up the install last night about 11pm. Turbos seems to pull hard and we should have some numbers soon. To be clear I do not think these are going to add a bunch more power over stock. They do flow about 15% more air and should see some gains with a good tune over stockers. Also I decided to go with a stock turbine over the clipped. We have have done clipped in the past and have had varying results. I feel the stock wheel coupled with the 14T MHI wheel is a good combo for some increased airflow while keeping the factory spool. I am doing the intro price on these at $1299 without the SS flapper upgrade, if you want the wastegates upgraded to the SS valves, Add $300 to that and we can't ship for another 2 weeks til the valves come in. This Intro price is good for one week from today then the retail price of $1499 will kick in. Pm me or Email if anyone has any interest. The Stage 2's are still just waiting for the SS valves and the final turbine housing machining and I should be shipping to the betas once I get that finished and test a set on our test car. Now that I have this install done I can turn back to the stage 3 test car and get back to work on fabbing. Thanks again for all your patience.

    There really is no reason to get a replacement set of stockers when these are for sale. Definitely a great deal.

    What's the benefit of a SS flapper upgrade?

    Takes care of the rattle and the wearing out of the stock flappers which get loose in the bore they rotate in and eventually lead to the rattling issue. In my opinion BMW allowed for too much clearance on the stock valves in the bore. You do have to take intake account heat expansion but even said I feel it was excessive from the cores I have seen and how much play they had.

    +1 can't wait to see some gains. If your stockers are going out and these make even the most minimal gain, they're still a good deal compared to oem ones.

    (Noob Question)

    So basically the rundown is:
    Stage 1=Stock turbos with minor tweaks to make them more reliable/no rattles
    Stage 2= Comparable to RB turbos
    Stage 3=Big twins with new manifold

    Correct?

    Close, to clarify simple break down is as follows.

    Stage 1A = Stock turbine - Bigger compressor MHI 14T compressor 40mm inducer / 51 mm exducer compared to 35.60mm inducer / 46mm exducer for stock. Essentially a fresh stock turbo with a bigger compressor that will flow close to 15% more at the same rotational speed as the stock wheel. (The customer who had them installed last night is telling me with the same procede map #2 he was running prior to the install he is running leaner which makes sense as the bigger compressor is flowing more air. He will be getting his DME reflashed and also uploading an upgraded turbo map and we will be dynoing the car next week to see some numbers.)

    Stage 1B = Same as above with Billet SS wastegate valve installed in turbine housing

    Stage 2 = Comparable to RB's - TD04 turbine, TD04 15T compressor 42mm inducer / 56 mm exducer, upgraded wastegate valves to billet SS. Will flow about 40% more then a stock turbo or 25% more then a stage 1 but the bigger turbine wheel helps to improve the backpressure issue of the stock turbine so you can push them harder before they hit the turbine bottleneck.

    Stage 3 = Yes GTX2863's new manifolds, new DP's, intake piping, charge piping to intercooler.

    Hope that helps.

    Awesome progress!

    But I don't see why he would run lean?

    O2 sensors and closed loop fuel system should compensate for the additional airflow and add fuel to still target the same AF ratio........unless he was maxing out his fuel trims?

    Was he running any meth as secondary fueling?

    Yes, I have taken 4 deposits for beta testers and 1 for the intro price of $1999 for stage 2's I am doing 5 sets at the intro price once the first 5 people have been set the price will go to the retail of $2499-$2999 I haven't decided on the exact price yet. The deposit for the stage 2's is 50%, then once they are ready to ship the balance plus a $400 core charge (RHD 335's 135's 1M's subject to a higher core charge) will be due. The website should be live today and you can pay your deposit from the site or you can call me at the shop do a credit card over the phone.

    Edit: Want to be clear. The core charge is fully refunded once I receive your cores.

    I am just going off what he has told me, I am assuming he did some logging. I will have more info this week when we dyno the car.

    Good work Tony, if you move half as quickly on the Stage 3s as you moved on these, and price them the way you previously discussed, you can definitely expect a deluge of orders.

    Have you heard any more from your wastegate/machining guys? All this talk is making me crave my stage 2's that much more
