There could be many variables associated with S’s car. It will get sorted out. Very few people have made good power on these setups and it’s for a reason. It isnt just plug and play. Having tried almost every combo on this motor I can attest to that. |

Bad mouthing and talking about the issues you have and the opinions of people are two different things. I think its a bit unprofessional to attack a customer you've never met or spoken to like this but I give them a pass. Email/text/forums is a tough way of communicating intent. That's right I don't know whats wrong with my car. Thanks for saying that again. I am not trying to be sarcastic. I am here for positive adult discussions that produce results.

There's stuff to be sorted out. Not sure why everyone gets their hair on fire. Simply discussing how we get to good results. Which everyone should want here. I am looking forward to talking with Mission. There's no gain in assigning blame. All we can do is compare opinions, use the facts we know and go through a process of elimination.

Did you use Pure turbos on your Carbahn built engine ? You also were not running 91 octane fuel correct ? |

So Mission Performance: You still have not responded to me, your customer. I've also direct messaged you. No response. Jesse @ Pure turbos has emailed you. No response. You have alluded to ~550wtq blowing 900tq spec clutches from SSP? You have accused the exhaust being an issue, which is just not true. That cannot max a turbo out because of factory cats. We have PLENTY of examples. The fuel certainly is a limitation and if we have a 163whp over stock as you say then were in a good spot and you did a great job. However... the turbos maxing out does not make sense and may not be your issue at all but looking for you to help and collaborate on solving this. Lot's of your statements don't add up, I am sure you were just a bit hot when responding. Whomever texted you clearly heated you up. Do you want to work with me (your client) or just come out over aggressive and out of line here on the forum. Not a good look, I have only heard great things about you before and I wouldn't want this to be negative towards your business. That's why I am reaching out for your assistance. I'm more than willing to let it go and start over but really disappointing as your client to be treated this way with this much time passing and no response after I've extended the olive branch. Email me so we can setup a call. I've been very patient and nice.

I had OEM turbos briefly while breaking-in the motor and it ran fine. After that I switched to the Pure X setup (Garrett GTX3076R). Car never saw < 95 octane + meth. All > 1000whp pulls were C16 + meth |

There should be NO impact for this combination. The Carbahn is just like a stock motor just 0.5 less compression.

I know I've seen your pure s1 vs s2 vs X post, however I don't recall if they were also tested on the carbahn motor or not. I know the X should be on the built engine. Could you confirm if s1 and s2 was on the same motor. Last edited by tonydat1; 03-09-2019 at 06:26 AM.. |

From a conversation with them that is why they go with Silly Rabbit Motorsport turbos which have a different center cartridge due to the OEM becoming a restriction. I have not found a vendor with a built engine that released data on which turbos they chose to use and why. |

What company or shop is doing your motor, if you don't mind me asking?

I did notice a key piece from the MissionPerformance post that you might have missed. They said, "From the start, the shop your car was built at has informed you that you wont be making any serious SAFE power on Cali 91 and stock cats, no matter what else you do to your car." Three qualifiers: safe power, Cali 91, and stock cats. Maybe that's where you should start with your engine issues. |

The "delta" is what anyone's focus should be. Before, during and after testing on the same dyno, same operator etc. to show the actual gains rather then only an overall number at the end of testing. An M6 with downpipes, software and 101 octane posted on these forums years back made low 600's on a mustang dyno in southern calrifornia then went to European Auto Source's Dyno Jet 2 days later and made close to 720WHP If I was a company advertising high numbers I would want to show the highest possible due to wanting to entice people to buy a product. Data of how the engine is running is what myself and hopefully he majority would. Maximum PSI and RK Tunes are currently testing S55 engines with ported cylinder heads and should be releasing data soon showing that with a stock cylinder head there is more power to be made then a ported cylinder head. They are testing a few internal engine components like valve springs for example. They replaced the valve springs on the ported head and now they are making huge numbers. I do believe that the Carbahn S63TU engine uses stock valve springs currently. There possibly could be some parts that are an influence which would require an engine builder / tuner to shine more technical data. Again..lots of variables to take into consideration |

You need valve springs IF you are going with an aggressive cam, revving the motor much higher (prevent float) or just running so much boost that the springs can't hold the valve shut (we are talking 45psi+). The carbahn spec S2 motor is a very simple motor done right. Every other motor/setup has just blown up or never started in the first place. People get tied up to the hype and end up getting ripped off. The fact that even shop cars never really ran right is very telling. |

Steve Dinan (Carbahn) came up with a formula to have a nice all around built engine. Its those wanting to push the envelope further that run into complications. |
