B58 Turbo Options
In this video, I talk about the turbo options that are available for the B58. I talked about the pros/cons of each kit, and what power you can expect depending on fuel support. Hope this helps

Already knew everything, but always like watching your videos. Straight to the point and easy to understand especially for newcomers to the platform. They ought to sticky your videos in B58 Enthusiasts for people so we stop getting the same questions over and over.

Again thanks mate for the the video and valuable information.
You are always a credible source of information but to be honest a bit skeptical about Twisted tuning and Pure Turbos gains of the bigger turbo + TU pump running on 93 only. From your videos stock turbo makes 400-420 WHP and by installing a bigger turbo and TU pump running on 93 only produce around 550 WHP. That's at least a full 130 WHP gain!! I think we need to have more evidence and facts about this like a real before and after dyno run done by an independent owner. Or are you 100% sure those claims are correct before I pull the trigger and buy the Pure 800 + TU pump ?

My understanding of the hybrid kits is they use the stock exhaust housing that has been machined out. The GC+ kit casts their own manifold and housing nothing is stock. Granted it's not a big turbo but wouldn't that make it not a hybrid but its own kit? Pure 800 still uses the factory housing that they modified. Which is why they still charge a core where Vargas GC+ does not.

Thanks mate yeah I know a custom tune is needed, problem is when I emailed MHD tuner and Jordan Tuned they both confirmed I will not see a reasonable gains without Ethanol.

Stock turbo can push over 500whp in some applications so you might be going off of his low end numbers for one and high end for another, that could also account for the big jump, Stock can easily handle over 440hp with upgraded HPFP so the jump isn't as large on average. 60hp or so with better turbo and tune. 480 to 540 type thing. Ethanol is where the big jump comes in though. That is what usually is needed to push our cars over the 600 mark (or meth)

I had high hopes of reaching 500+ wheel on Pure 800 92 octane, but with a custom tune I ended up getting about 440-450 wheel (not officially dyno'd) just guesstimates by races and other people's inputs. Also there was a video online of someone who dynod their 93 octane Pure 800 custom tune and he only got about 470ish which makes sense for a 1 octane jump. These are the numbers I would expect from my experience, hope that helps. |

GC 100Ron = 520whp
GC 100Ron + WMI = 580whp GC 100Ron+50%109Ron +30%E85 + WMI = 626whp. From which it can be seen that fuel is the limiting factor in power on the B58. Hybrid turbines GC, Pure800, GC + are effective only at octane above 102/105 and above 600whp, additional injection of WMI, PI, etc. is needed.

Not sure why you assumed I don't know how HPFP works Anyway looking forward to watching your fueling video, Cheers mate.

Here's another example. Vargas put their car on a dyno, just swapping turbos on an OTS map. Look at the results. https://f30.bimmerpost.com/forums/sh....php?t=1671520 Quote:

I am surprised to see so many folks are focusing on whp vs. % gain from stock. I get it because it's nice to be able to throw out a #, but unless everyone is using the same dyno to measure whp, it is sort of a moot point. Example: 450whp on a mustang or dyno dynamics may read 520whp on a dynojet. That's all nice, but you need to know where you started in stock form, on the same dyno.

As far as I know Jordan Tuned are one of the best names in tuning even in the link you provided below VTTO chose them for making their custom tune so there must be something behind their plug recommendation to customers.
Also in this link the VTTO bigger Turbo achieved around 440 whp on OTS tunes not sure a custom tune will add another 110 whp on 93 only. I always check extensively from different sources before I consider anything a FACT and I heard different results when using a bigger Turbo with 93 octane actually one of them in this thread: https://f30.bimmerpost.com/forums/sh...6&postcount=11 Quote:

And read that thread again. It's a pure800, and it hit 470whp on a conservative tune. You can be skeptical all you want, but the numbers have been proven over and over. Watch my video on fuel upgrades and see if it doesn't make more sense. it's all about where the turbo makes power. |

Chill mate we and remember we are doing all those discussions for the sake and to help our B58 community.
Most of us worked hard to be able to buy these cars and we deserve to have the best products as advertised. You know companies sometimes make inaccurate claims about their products, remember when you were not happy when you found your CSF heat exchanger results not exactly like the chart they advertised ? I was told by multiple sources that a bigger Turbo on 93 does not make huge gains so I thought it's my responsibility to share it on the forum, same like your experience with Cary Jordan I'll definitely keep that in mind. Cheers mate. Quote:

Yeah...I wasn't commenting on your video and appreciate the fact you mention the dyno jet to clarify. I agree it's common language yes, but we both know a 500hp car on a dynojet will likely hit maybe 450 on a dyno dynamics or mustang, hence peak HP is not measured in a common manner. My point is someone above said they were disappointed with 450whp...unless we are all using the same machine, on the same day, it's just a number. 1/4mi times would be better, but the b58 is in too many cars to compare apples to apples.
