Just finished up this kit, car is tuned waiting to dyno soon

 

neat

 

Not quite how I'd describe that picture

 

sure it was a mistake or something, but this is kinda a weird place to post about a non-single turbo setup..

 

^ Your sig quotes made me

 

Can you please give us more info on this setup? What turbos are you using? What made you want to stay with twins vs. going single?

 

This is really cool. Please add more information about the build including engine build, type of turbos, etc.

Is each rotor basically driving one turbo in a traditional non-sequential fashion?

 

Judging by the picture is a non sequential setup running garrett g28r compressor housing styles maybe on t3 hotsides.It does look nice just need need some cleaning.Keep up the good work.

 

We decided to build a manifold that supplies both turbo's at the same time rather that runing both turbo's off one runner.

 

Mods are
largerstreet port
1600cc and 850cc injectors
meth kit
3.5 exhaust
apex pfc
hks twinpower

 

Very neat. What kind of boost are you running with and without meth? I know you haven't dyno'd it yet but what does your butt tell you in terms of power and how does it feel in the upper RPM range? i.e. where does it feel like it starts to fall off?

 

no point if they're not sequential.

 

Customer had the car dyno here is a copy of the graph, it's not a great one. The car was dyno in 3rd gear, there is no boost on the graph and the graph starts at 3500. You can't see where the boost start at the car was dyno on a Mustang Dyno so i guessing about 12%-15% drivetrain loss, I'm gussing it's making around 360rwhp- 370rwhp at 14lbs of boost. I like that the turbo's are still pulling up top in the higher rpm, we will tune it for about 20lbs - 22lbs this springs

 

Seems rather anti-climatic. Why go through ALL that effort for similar power to sequential twins (you can't just "guestimate" an extra 50whp in there...) with none of the low end performance?

I'd be pretty disappointed (and pissed off) if I shelled out a bunch of cash and that's what I got in return... A well made mid-sized turbo kit will give you better power, response, and performance across the entire powerband.

 

Yep. only the 335i is a modern car that uses twin turbos not seq.

 

Yeah, but we're not talking about inline 6 engines here. (I've owned my '07 335i since early 2010... I'd happily watch it burn to a crisp in a BLM riot... )

 

Its a know fact that mustang dyno read 12%-15% lower, maybe you should try reading up on it. Also this is a progeress in the works, we will make adjustment with this kit to see what works and what does not.

 

I'm well aware of how people like to use the dyno type as an excuse for low numbers. That's still no excuse for the fact that you're waiting until OVER 5krpms for any power on a twin setup.. (that's just ****-poor planning if you go to a "heartbreak" dyno to do power runs for the sole purpose of internet bragging rights btw )

Your "product" both looks amateur and apparently performs the same way, so I stand behind saying that I'd be pissed if I paid you hard earned money, and you gave THAT in exchange. Your "kit" made approx 315whp-325whp at 14psi. My twins made that same power on a DynoDynamics dyno in the UK with a pig-rich tune with LOTS of room for improvement. The difference being that those twins actually had power and response below the hp/tq crossover

Ironically, my car showed similar power levels as the DD when it was put on the dynojet (or whatever Dyno they had at PFS) when I moved back to the US. So your excuse doesn't mean much to me as I've had my car on both types running the same map and noticed that the spread isn't as large as one would think..

 

Interesting setup and clean fab work but agreed that its not really worth it on a 2 rotor as a modern well sorted single will easily outspool and outpower twins. Also, clamping -an line is a big no no. I would change the overflow hose and whatever else yo have clamped like that. Remove the nipples out of the housings and tap for a npt to -an fitting.

 

Thanks for the input, but based on the other forum, its a paper weight.
