What People forget is that there is no core charge.
When you purchase PS2+ turbo's you in for 4k and core charge and have no additional turbo's when you return the core for your credit. with these units you can sell your stockers which are worth about 3k or return it to stock and sell ASR kratos turbo's. So i personally think you end up at the same price point of most of the hybrid turbo's without a core charge. So essentially it works out the same |

In regards to the additional cost of the titanium being worth it for pump fuel is relative to your use. Being that it's a more aggressive design and higher flowing wheel, it will produce more power even at pump gas boost levels as compared to our standard billet option. However, that power difference will increase exponentially as boost increases with higher octane fuels. For most daily driver street cars though, the KRAS55Bi would probably be the more cost effective option for pump gas as the difference in power at that boost level is more so a limit of octane rather than flow capability. |

I absolutely don't need any more engine power, but I do want these turbos. Quicker spool up with less back pressure for more big cubic inch NA like power delivery. |

Why the switch to a built motor? Wouldn't it have been more prudent for your market to display the standard billet turbo at the dragstrip and 60-130 against your main competition since that would be 90%+ of the people thinking about upgraded turbos? Did the motor let go at 850whp advertised as disproving the naysayers?
Thanks. |

I was just reading the VTT GC thread and came across this. Sounds very interesting, and the "extra" premium just sounds like an insurance policy IMO.
With the emphasis being on reducing back pressure, anyway we could run these on stock cats for the guys who want 600/600 but wish to remain emmissions compliant? ETA for availability? Also, I have a Dinan stage 3, with the comments you made that tune to tune, you should get more power gains from you turbos compared to stock oem ones, same correlation here too with Dinan piggyback? If these are truly plug and play in that regard as well as the physical install, then I think Kratos has a compelling story for the street guys. Thank you in advance.

Our statement regarding disproving the naysayers was directed towards the preconceived notion that the stock connecting rods are only safe up to approximately 700whp. This was disproved with our KRAS55Bi as the mechanical limit of the connecting rods has more to do with extreme backpressures of stock manifolds as well as high torque demand tuning. This particular stock engine beta test car has endured over 20K miles of daily driving and abuse with our KRAS55Bi's installed with a large portion of those miles driven at well over 750whp. As of late the same car has approximately 3500 miles logged at the current 812whp level without fail. |

While back pressure is a major hurdle that we've addressed, it's a culmination of the design and engineering process of the complete system that brings it all together. The flow capabilities and power output of our systems at a given boost pressure are among the many highlights of how our KRAS55Bi differs from others. For example, this same built engine S55 produced 758whp at only 25psi. This is significantly more power than any OEM style cast or hybrid S55 turbo system as ever produced at the given boost level. Less boost means less heat and less stress on all engine components which increases consistency of power output, durability, and reliability. Yes, you can run stock cats with our KRAS55Bi's or any of our turbo systems for that matter. Stock cats will reduce power output a bit, but we see no reason as to why you can't produce 600whp safely and easily on pump gas with our KRAS55Bi's on stock cats. However, we do not recommend running the same tune made for stock turbos or any other systems for that matter with our turbos as tuning parameters must adhere to the hardware that's installed on the vehicle. Our turbos do have a higher power output at a given boost level as compared to other turbo systems, but we would recommend getting in touch with BM3 for shelf maps we're working on creating with them for our KRAS55 turbo offerings. Customers are also urged to contact Halim@HCP for any custom tune requests. |

Have you guys tried acceleration tests like 60-130? We saw all the dyno and detailed information about your turbos except that you guys are hiding the actual turbo specs but can you share the 60-130? I would really like to know what these turbos can do on stock engine |

As part of the discussion in our 1150whp press release, we discussed how usable the powerband is and how it would all be dependent on your drivetrain upgrades and wheel/tire combination you're running. As far as normal partial throttle driving, the car drives completely docile just like a stock M3 which is one of the best aspects about the turbo system. However, under WOT that is a different story. Without any sort of boost reduction even at 22psi (748whp/657wtq Built Engine) from a roll in 2nd gear with 2 people in the car on Michelin Pilot 4S's, it spins all of 2nd and all of 3rd gear without any signs of traction early in 4th before throttle is lifted. This is a prime example as to why KRAS55Bi owners will need either R888R's or some sort of drag radial if they plan on running the car without boost reduction on the street or strip. Attached below is a sample video of this run in Mexico to show how much of a handful the car can actually be on street tires without boost reduction at only 22psi. Note: Sport Display has been modified to reflect 960 Horsepower / 800 Torque. Not that they are very accurate, but we figured it was still worth mentioning.

The development car in the video has stock drivetrain (stock axles, driveshaft etc.) and is not meant to be a prepped drag car. This car is better suited for ½ mile as opposed to ¼ mile testing. As a result of the stock drivetrain we did not launch the car. Even spinning through all of 1st, 2nd and pedaling through 3rd, while short shifting, the car put up a very respectable 149.54mph as per the dragy. Boost was limited to 30 PSI (Approximately High 800whp) to try to cope with traction problems but even still, the car was spinning! We feel that customers with similar builds on the same KRAS55Bi's at 41psi (1150whp) with the correct wheel/tire combo and drivetrain upgrades can easily accomplish high 150mph passes and quite possibly 160mph down the 1/4 mile! Please contact info@asrkratos.com if you are interested in reserving one of said pre-order units. Last edited by Sales@KRATOS; 03-18-2019 at 02:29 PM.. |

TRACTION LIMITED Latest 60-130mph/100-200kph results. This is while spinning and at 30psi! Approximately high 800whp. These results were recorded on the same pass that the car did 149.54mph in the 1/4.
