    Yeah I am very tempted but am going to wait on more results/longevity. I think I will stick with PI for now.

    They provided detailed info on failure modes of HPFPs. This is the only post I have seen calling injectors into question.

    1 head and 4 sets of the B58 Valvetronic suppports to experiment and make MILVs for the B58. 2020 Supra head looks to be similar everywhere except the integrated 2 port exhaust manifold. I suspect that the 2020 BMW B58 will have the same integrated exhaust manifold. The only 2020 Supra head that I have seen is on Papadakis's B58 teardown video. Now if he would only send out that head and get it bench flowed.

    You said you ordered four sets of heads. Are they all from the same style B58 motor? The Supra head obviously will be difference due to the casting but everything else should be the same, right?

    So what are these pics and what do I like- Head- very compact latest design, valvetronic eccentric cam and mechanism moved around, No exhaust cam clamshell like Nxx engines, Heavy, must be thicker in all the right places Supports for Intake Valvetronic- up high right on top, easy access, easy removal and replacement, hint MILVs? HPFP- mounts up high right on top, easy access, driven by 3 lobed on exhaust cam, easy to upgrade/replace, hint Xtreme DI Exhaust ports and close up exhaust port- big oval Intake ports and close up intake port- big oval Combustion Chamber and close up- very compact Valvetronic Eccentric cam Motor- externally mounted, up front, easy access, has hex screw to rotate manually

    This stuff is being pushed hard on social media and it seems dealers just got their Helix's in. Nobody is addressing any of the engineering and technical questions raised though. Spool Performance never even admitted to any failures which is disconcerting. They seem more interested in sales than solutions. Sure is going to be interesting to see how it pans out...

    Didn't sleep well so I got up early and took a pair of calipers to the B58 head that I have. Ports are BIG. B58 Intake is Oval shape- 35.7mm tall x 50mm wide. Not 'rectoval' like the N54/N55 at 29mm x 50mm. B58 Exhaust is also Oval- 29.2mm x 45.7mm wide. Not round like the N54/N55. B58 Valves measure- Intake 29.9-30.0mm, Exhaust 28.4mm. N52/N54/N55 Exhaust valves are all 28mm. N52 intake valves- 34.2mm, N54- 31.4mm, N55- 32mm. So just by 'looks', the B58 head is an improvement. Exhaust especially, Bigger ports and Bigger valves = more flow. Intake, maybe not so much, Bigger ports and smaller valves. IDK, but maybe that combination is better flowing than smaller ports and bigger valves. Or is there another reason or something else going on? The intake valves look to be moved out and right at the edge of the cylinder bore. It doesn't look like a bigger intake valve diameter would fit. Don't throw stones about the B58's 'smaller' intake valves just yet. Interesting is the different engines actual measurements. N52- 85mm bore x 88mm stroke = 2996cc and has the biggest intake valve 34.2mm. Cam is I-255*/E-263* durations. N54/55- 84mm bore x 89.6mm stroke = 2979cc and have 31.4mm and 32mm intake valves. Cams are N54- I-245*/E-261* and N55- I-255*/263* durations. B58- 82mm bore x 94.6mm stroke = 2998cc and has 30mm intake valves which looks to be the largest that would fit the 82mm bore. Cams to be determined. There is a correlation between cylinder bore diameter and intake valve size. Just some simple, basic engine generalities- Bigger bore (bigger intake valve) and shorter stroke make for a higher rev'ing engine. N52 engine. Smaller bore (smaller intake valve) and longer stroke makes for better intake filling and more torque and power across a broader rpm range. B58 engine. Without a doubt, BMW did their homework. The B58 engine looks very promising!!

    You likely have noticed many articles about TTE (The Turbo Engineers) lately as they seem to have a hybrid turbocharger upgrade for basically any platform. They are usually the first to market as well as evidenced by their recent Lamborghini Urus upgrade. You name it, they have a turbo upgrade. BoostAddict did not know how large their reach was until speaking with Simon Sharp of Sharp Motorsport Ltd. This network of sites can often be quite critical as we question pricing trying to keep vendors honest and being located in the USA we use dollar priced products as the barometer. Now is a good time to mention we were very wrong in our criticism of TTE's Porsche 991.2 GT2 RS TTE1200 VTG turbo upgrade. Why? Because much like the X51 package for the Porsche 991.2 3.0 Carrera models a VIN must be provided to Porsche to get the turbochargers which are then modified. Buying Porsche factory parts directly is not cheap. There are few VINS to go around and few GT2 RS owners that modify their cars. It is not the same as machining some housings off a volume model and the price reflects the cost of the VTG's to begin with from Porsche then the work TTE has to do in order to get them to support 1200+ horsepower level of output. PorscheBoost got it wrong saying the price was absurd. On the bright side, TTE Global is aboard the network as a premium vendor and they are expanding their reach worldwide. APR recently tuned some 2.5 TFSI models equipped with TTE hybrids for example. Additionally, TTE offers the largest volume of hybrid turbocharger upgrades in Europe. Many of those big Euro tuning houses you hear of go to TTE and private label. We will not name names but you have likely heard of a certain very big Porsche tuner with a single syllable name. Yep, they go to TTE. As do some AMG tuning houses by the way. They are number one for a reason and it is because their products work. Yes, on a direct dollar conversion some of their turbos are more expensive than US competition but you know what you get for that money? A quality product that works and lasts. They are not sourcing cheap Chinese garbage. People will pay for quality. BoostAddict will cover the TTE Global product line: https://tteglobal.com/ You can expect to see more of their turbo upgrades in the USA. Welcome aboard TTE Global!

    I agree with your comment on the timing corrections. I wish I knew how to get eliminate them or at least reduce them. Dimitri @ BQ Tuning has been trying from his end. Certainly, the trap speed is less than it should be. I had another 2 runs last night. On the 1st run, I tried a 2nd gear launch with no success. After launching, it automatically changed into 3rd at 3,800 rpm which killed the run. Got a 11.159s @ 127.78 mph. On the 2nd run, I did a 1st gear launch and managed a 10.927s @ 128.35 mph. 60' time on the 2nd run was 1.64s compared to a 1.944s on the 1st run.

    Not a ton of 10-second RHD hybrid results to report but this is great to see. BimmerBoost members in the United Kingdom as well as Australia in particular will take notice of this result on a full weight E92 335i and of course the Nizpro upgraded automatic is helping that elapsed time. Rob Beck covered the details below: Not a real common feat for this platform, especially on twins and stock'ish powertrain, while full weight. Even more so unique is that I believe this maybe the first RHD car to ever hit 10's period? (That is of course barring those running power glides) At any rate great short times helped this one along, but still pretty deep into the 10's so it is not like it just eek'd it's way in there in the process. Back to the OE'ish power train and full weight category, this is the 2nd quickest 1/4 ET I recall ever seeing... but it is open for discussion as well. Anyway here is all of the information that was provided, including the timeslip, below.
