I just ordered the GC+ for my 2015 535i here in the States. I’m FBO running direct port Meth. What you figure I could get on the GC+ with the direct port 50/50 Meth 93 octane? I know the B58 has some forged stuff lol. Thanks. Love the content.

[@DjNikGnashers]

Great video, and something which I am now considering as the next step. Mine made 455bhp/634nm just with a Wagner 200 cell cat, ITG panel filter and map. I would like a charge cooler rad upgrade, Dorch stage 2 hpfp, and Pure800 turbo, to try and hit 600bhp on 99ron.

[@NVMotorsportUK]

600 on 99 ron will need a bigger AR

[@DjNikGnashers]

@@NVMotorsportUK AR ? And thanks for the reply matey.

[@NVMotorsportUK]

A/R stands for Area over Radius. It is defined as the inlet (or, for compressor housings, the discharge) cross-sectional area divided by the radius from the turbo centerline to the centroid of that area. Bigger AR equals less back pressure.. more lag.. but increased air mass.

[@DjNikGnashers]

@@NVMotorsportUK Thank you, and it makes sense now you have explained. So what you are saying is : it's mechanically impossible to make 600bhp on 99ron without significant changes to the design of the engine ? I'm not really a fan of meth as I daily drive mine, and don't want the hassle of filling another tank up.

[@DjNikGnashers]

@@NVMotorsportUK I will continue this enquiry via your website contact form ...

[@BAZZERBAZ]

Would the vtt gc be the better option if only running 99ron?

[@bigmatt2896]

great informative video, is this the same engine as in the 2017 5 series 540i?

[@NVMotorsportUK]

Yes

[@mariand9960]

On those b58 isn't unsafe to run meth just trough the charge pipe ? Due the position on the throttle body ?

[@NVMotorsportUK]

No if you stay below 1000cc and use a progressive controller with cam adjustments

[@pissywilly]

Is ethanol available in the uk yet? I moved to Florida from Cheshire 4 years ago. A decent amount of petrol stations have E pumps over here. Running a stage 2 e30 map MHD stock turbo and hpfp and pushing 500bhp. 2018 440i gran coupe

[@NVMotorsportUK]

Was that ran on a dyno that measures loss or did you use a multiplier on a dynonjet?

[@pissywilly]

@@NVMotorsportUK it was a dynojet 430whp the tuner said a little over 500 crank with a rwd 8at

[@NVMotorsportUK]

@@pissywilly we did cover this in a previous vlog.. guessing it ran 330ish whp stock?

[@pissywilly]

@@NVMotorsportUK never got a baseline was just a power run. It's flashed MHD ots so not a custom dyno tune before and after

[@NVMotorsportUK]

Most B58 on latest SWFL make around 355bhp stock with dp.. so if they run 330whp on a dynojet.. the fixed transloss can be equivalent to 25hp.. if that is the case then you can add that to the tuned whp and get a more realistic figure of 455 bhp in UK.. this can be checksummed simply by finding the rpm at which it makes peak.. note the torque in nm.. multiply by the rpm divided by 5252👍🏾

Keep it

[@SuperVarunan]

How is this build holding up? Any issues with the chargepipe meth over time?

[@NVMotorsportUK]

No

[@SuperVarunan]

@@NVMotorsportUK Awesome, thanks for the input I'm looking to do a similar build. I'm interested on running a 91 Octane /95 RON tune with chargepipe meth injection, since in some parts.of Canada I can't find 93 octane consistently, do you think the TU HPFP would be enough to fulfill whatever turbo I go for or should I spring for a dorch/fuel it stage 1 or 2?

[@FutureGameLight]

600hp as max on the b58? there are many people running around 700hp on a completely stock block and internals for a long time now.

[@NVMotorsportUK]

On e85 all day long. If you watched the full video. We are talking 99

[@FutureGameLight]

@@NVMotorsportUK these numbers are still much to low. in germany we drive them with 102 octan (99 or 98 octan for you guys i cant really remember the correct conversion) with 700hp

[@NVMotorsportUK]

Germany 102 is the same as uk 102 not 99.

[@jim8462]

Hi how much power would you say I could get upgrading the turbo and fuel pump on my m2 ? No decat as I have a sports cat and I don’t want to run meth car is already stage 2 . Love the vids 🚗 💨

[@NVMotorsportUK]

Totally depends on turbo option

[@jim8462]

@@NVMotorsportUK I was thinking about going Pure turbos as it’s 2.5k I don’t fancy spending 5k on a turbo I can’t justify it. Thanks for the response.

[@B58J]

How much bhp/whp would you expect on a vargas gc (not plus) Supra Tu hpfp Vrsf sports cat Mppsk Xhp Tu plugs Thanks

[@NVMotorsportUK]

Similar to the figures in this vid with better spool.

[@DamnDudeGetaLife]

@@NVMotorsportUK So the only benefit on the GC+ over the GC is once you add meth injection or e85?

[@NVMotorsportUK]

Yes
