S58 potential, value proposition and rivals
I've been struggling to have conversations that don't involve the grille sucks (which i also don't like) so with all the cosmetics discussions going on, lets talk about the potential of the S58 engine, particularly in the M3/M4 comp and their performance to value proposition.
An X3M with an ECU tune has shown the S58 in a larger package to be a 3.0s and 11s car to 60 and 1/4, respectively. Clearly the S58 is capable of holding 600+ whp and with 400-600lbs less, is the G8x setting the new benchmark in the industry in terms of performance per dollar? Other than the C8 Corvette, muscle cars and M2CS / G87, C63 are there any other cars that can truly match the S58 dollar per dollar (under $85k USD)? Who else is a competitor in this class? Would like to keep this civil and an educational discussion please. Last edited by Avaley; 09-23-2020 at 01:29 PM.. |

That's what my gut says, anyway. Examples like this immediately come to mind: https://www.caranddriver.com/news/a2...-supercharger/ Then there's Hellcats. I could also being up the "T" word, but let's just not. Quote:
If you are looking for bragging rights, there should be some specific areas where the G8x comes out in the top spot, particularly the G80 since its a sedan and high performance sedans are less prolific than coupes. The AWD model is also going to occupy a smaller niche too, with the M4 in particular being something of a neo-GT-R at a much lower price-point. So maybe not necessarily game changing territory, but certainly great value at any rate. |

I'll drop the Tesla word since im not myopic on brand and try to be objective...now that a model 3P and m4 are both about 4,000 lbs, does the G8x justify a 10-15k premium over a model 3P? while purists will hate this, battery range, cost, performance and weight will eventually push traditional ICU engines to innovate, for the benefit of us, the consumer. better yet i4m in 2028 anyone? |

I think this will indeed be a new benchmark for performance.
It is completely nuts that with a stage 1 tune you get 600whp on pump 93. Although I'm not the target audience for the AWD version (I don't care about 0-60) the performance is going to be quite nuts. edit: look at this insanity: Stage 1 (91-93) vs Stock

I also feel pretty good that the S58 engine has been out awhile in the X3M/X4M and that the tunes have been street tested thoroughly. Everything we all did to our S55's, in most cases, we were the guinea pigs for.

That curve also tells me the new turbos (S58) are way bigger than the old ones (S55). I can't think of any car that gains 150whp on 93 octane with just a stage 1 tune. It's just crazy. [Remember the comp dynos at 460whp on 93] |

700whp car with FBO. Which I would dare to say 2.6-2.7s 0-60 and solid 10 second car with launch control before big turbos for AWD comp.

I think the Tesla M3 is a good comp, but it's quite boring interior and exterior. Without going to far into it, the BMW M3/M4 at least look unique and "special". the Model 3 just looks like a bean.
C8 vs M4, unless you need the back seats, C8 imo. Maybe a 718 GTS or base 911, but those are quite a bit pricier. Your opinion on porsche may sway you that direction. I think they're very expensive for what you get. M3 only competitor I can think of that will match as an all around package would be the upcoming C AMGs and those are supposedly moving to 4cyls. as far as 4 door practicality and performance, the BMW M3 is the clear choice, unless you absolutely can't stand the you know what... I actually kind of like it haha

They should have changed the redline for the 6MT as that does not share those limitations |

xHP flashtool is great on BMW trans and I'm sure they will work their magic on the M8HP76 and 6MT. While an 8AT will never be a DCT performance wise , the newest ones are darn good, im cautiously optimistic (fyi the purist in me died long ago). Does anyone have any insight into the M8HP76 performance? |

Depends on how it is built, base wheels? yea, if you go with SPASM and set it up correctly the new 992s look amazing. 991.2 GTS and 991.2 T are also both good looking cars. Last edited by neliconcept; 09-23-2020 at 01:51 PM.. |
