Pertinent to this thread I suppose.

Yup.

If you guys support a guy who's basically lying out of his ass and saying his product outperforms the competition and then says his R&D is miles ahead of the competition where his competitors have literally out sold his product for the last few years, idk what to say.

He doesn't even make B58 turbos and he says his R&D is miles ahead lmao.

What about this turbo kit? I saw someone elsewhere mention its capable of 700hp on an N55, but their page says about 500ish.

And what do you do about a wastegate on an EWG car?

BM3 has an option to disable OEM EWG for external wastegate controlled cars.

To be fair Doug Harper and Frankenturbo has been around for years. They were one of the first with Chinese turbo upgrades for the n54. However as Chinese turbos were in their infancy, there were huge quality assurance issues. These issues aren't around as much anymore, but do happen. It's a risk many people take these days to save a couple bucks as tooling gets better and better. if you really want to dig, there's a lot of debates + data on this from rb turbos/franken turbo/hexon turbos from spool street in the n54 section. you can also look at reviews on audizine, vwvortex to name a few. This same strategy of supplying "turbo upgrades" without data testing themselves has been a thing for awhile. before the n55 turbos it was the n20 motor which was hit with the razzle dazzle and underperformed. heck a 10+ year old "stage 1 turbo upgrade" outflowed their turbo upgrade + is a better buy for the price.

As frankenturbo is based in Portland, OR, public record show the company filed for bankruptcy a handful of times if you really want to dig into those public records.

This isn't new info, but for people who didn't know, the F30 n55 turbos are based on the Borg Warner efr series. Really and truly the stock turbo are a efr 5255 turbo. the smallest efr is a 6258 and on paper flows 43-44 lb/min. thus 430-450whp should be possible on e85 with the stock turbo and all supporting parts. Dyno have shown just under this as the bmw turbo is smaller.

Most of these turbo upgrades used to be genuine Borg Warner turbine wheels and slowly overtime swapped over to the Chinese turbine wheels due to supply chain issues from Borg. Thus your "pure stage 2" is between a efr 6758 and 7163 turbo. thus on paper should make 530-570whp on e85. dyno results have shown these numbers.

The newest "pure 750" is a efr 7163 spec'd turbine wheel with updated larger ar housing to allow for max flow + boost while not becoming a heat pump. On paper a efr 7163 is a 60 lb/min turbo thus 600-640whp should be possible in theory on e85. dyno results have shown these numbers.

Would you trust a company that hits you with the razzle dazzle without any actual data other than being good with words + was good previously with the China game cover-up? Now they are being called out for their hypocrisy. Make a great quality product and show data or be pushed out of the game.

take a gander at the YouTube video

I don’t know why Audi and other data is brought up.

That is like saying, ALL BMW engines suffer from the same issues just simply because it’s an engine in a BMW.

Let’s focus on facts and not on speculations or feelings. The quickest pure turbo n55 is Sixto on the n55 Facebook group. His F30 runs a 6.8 in the 1/8 mile, and the quickest n55+ car is a F10 and it runs the same 6.8 in the 1/8 mile with an additional ~300-400lbs of weight. I can you why, but even if I did more than half won’t understand it.

Someone posted a 91 oct Pure750 dyno on the BMW N55 group.

Their M2 N55 made 470whp/500wtq on straight 91 only with Pure750.

They said their E85 run is up next.

Did they ever find the dyno sheet?
