like fairbird said, the software needs to catch up to the hardware. This reminds me of the old smartphone days when the Microsoft products had all the beefy hardware but the Apple products ran much smoother and faster despite having inferior hardware. If the software isn't optimized to take advantage of the hardware, then the hardware is useless. We're all so hyped to see different upgraded turbo kits here but we're in a black box when it comes to knowing what the software can make out of it.

The big part I've noticed and now Weistec makes the Kit is the Diverter valve and meth.. Bypassing that stupid vacuum boost actuator and doing a manual setup I've found makes a big difference. Having more consistent boost in every gear across the board and the diverter valve to prevent backwards turbo pressure on shifts are all things that can be done without tuning. My guess is that the Y77 is just running of its own map because leaving it plugged in and bypassed has not thrown a code yet. The torque limits seem like they are far less in 1st and 2nd now that boost is the same. My car doesn't have a Tune on it so maybe that is done when they tune it I'm not sure

What kind of a software glitch will cause a car to run slower despite having 100whp more?

Fairbird

limp mode

efiftyfizzle

doesn't necessarily have to be software... could be IATs too. When weistec first released their supercharger for M113K, it had major heatsoak problems

e65

Both weistec cars that lost had trunk ice tank. Renntech car had stock cooling. Nobody was racing in limp mode.

e.french lied lol watch his vids im sure he started out as tune only but somewhere along the way he had to of upgraded turbos ... he beats mclaren 650s with little problem and they trap 135-138 in 1/4 and totally drops lambo huracan with no problem and they run 10.6/133 stock

he has renntech turbo upgrade lol... so now you know renntech turbo upgrade will beat a W3 which i dont think anyone doubted since renntech is full turbo upgrade (compressor and turbine) while W3 is just compressor upgrade

e65

If Efrench had Renntech turbo upgrade he should have beat the Aventador instead of losing to it

Renntech turbo upgrade beating aventador despite 4matic drivetrain losses

Efrench losing to Aventador with rwd e63, less drivetrainloss compared to 4matic

gaspam

he did beat that aventador in that vid , he was ahead the whole time

also that other video you post is not regular renntech turbo upgrade.. Its vasily in russia and he had renntech VIP stage, meaning it was custom setup making way more power than the standard renntech turbo kit... I think he was making close to 800whp while standard kit makes around 710whp

and check e frech out here putting bus lengths on BMS terry burger M5 shop car that traps 127 .... how is a stock turbo E63 going to put bus lengths on a M5 that traps 127 ? Forget about using e.french as a example of stock turbo e63

e65

Aventador was pulling on him the whole time but fine let's forget about eFrench. Ive seen w3 with ms109 losing to stock Huracan on pump gas. W3 losing to stock aventador, full w3 losing to tune only f10 m5. I specifically asked if I would be making 727 wheel horsepower on pump gas and I was told yes. They changed their website after the fact and revise it to 660, after I bought the parts. I have all the emails still.

As far as honesty the only guarantee I can give is for myself and this is my only consolation. The people that I've dealt with have lied to me over and over again for the sake of their company. Deliberately. There is no employer, sales commission, or any other person who is so important that one should sacrifice the weight of his own word.

I hope that in due time I can publish some dyno and track numbers. Real ones. With nothing to prove and with nothing to hide only to share. If my engine can be fixed.

I was thinking going with Weistec tune and turbo upgrade in the near future.
But, after reading this post.


I think I might hold it off, until they have better software to support those upgraded hardwares.

Fairbird

no m5 f10 in the world on pump gas could beat my w3 set up . And I don't care how much money the company making . It is what it is .

e65

If you ever get a chance to put it on a dyno let us know if you hit 660 to the wheels or somewhere in that ballpark.

Fairbird

without the dyno I can tell it was more than 660 awhp , 700+

e65

I'd like to know what you can tell me with the dyno

Fairbird

the car is a part for past month waiting on refund after turbochargers fail , NOT W3 !
going different rout

e65

Sorry to hear that.

If my engine can be rebuilt I will have the option of keeping my Powerhaus turbos and AMS carbon intake or go with the gad setup. I've asked them to let me know how much power my own parts produce to help me make that decision - it's an extra charge for that but I'm curious.

Gad top mount dual intercoolers will not work with the AMS intake. If I go with Gad partd I will be leftover with Powerhaus turbos and ams intake that I hope someone would buy from me theyre unused. I'm not sure what route you're planning to take next. The powerhaus turbos are w.3 hybrid, weistec compressor wheel with upgraded turbine wheel. ECM would need tune by Powerhaus.

My engine needs rebuild because of gouges in the cylinder walls. Nobody has any idea how that happened. I suspect that when everything was put together, weistec transmission, Powerhaus turbos, weistec exhaust, that someone forgot to put oil back in the engine before running the car. Pure speculation on my part but I can't think of how else this could have happened. I never drove in the car or even sat in my driver seat after everything was put together. Just got told that everything is running fine except for weistec exhaust not fitting and then oh by the way your engine is shot - just realized that as we attempted to take your car to an exhaust shop to try to repair your brand new weistec exhaust. 5000 miles on the motor.

ar u mopes3 on IG ? I don't have my E for 5 month already , it's on the lift all that time , thanks for our MB tuning industry and "tuners" , some trying to fix it , over 40k spent and no car , my last attempt with MB .

e65

I dont know what mopes3 on IG means, maybe you're referring to another person that would not be me.

Fairbird

another person lost his engine after Power house turbo upgrade at 5000 miles . the car at Dime racing for engine build

e65

Powerhaus told me they have never heard of this happening and that they have done over 20 of these with no issues. They got me a quote from Dime racing for rebuild. I've heard a lot of negative things about DIME and Rod. Maybe its not true but I didn't want to take a chance. Would have been far cheaper and far more convenient for me to send my car to California instead of Germany.

If you can get this other guy in contact with me I'd appreciate it.

Fairbird

It's true . I can not get him to contact you .

e65

Y not?

Fairbird

because I don't know him and to ask him contact somebody will sound weird

LaunchPad

I know this is a bit off topic however Are any of you guys with turbo upgrades running a lightweight wheel / rotor setup? Based on the subpar improvements ive seen with the turbo upgrades I bet a lightweight set of wheels and rotors will make almost as much as a difference .
