As others have stated, AFRs can be fine it's the ignition targets/corrections you should be concerned with. Though the guys at AR probably don't think that way.

Correct, You have to lower timing as you add boost. Adding higher boost to a lower boost tune can result in bad things happening.

The DME pulls/adds ignition accordingly, so I don't see how this would be an issue......

And here is an overlapped dyno of the ESS 625 "factory" 3.8 vs 3.6 vs 3.2 pullies
A solid 89hp and 51tq jump from 3psi increase.

If the DME is always pulling timing, that means there is always knock occurring. Even if it is slight knocking, at the stress level your car is going through its life will be short. Since you have no way to monitor ignition values on your car, be prepared to build sooner than later. Since you have experience with 1 ESS M3 and Roman has who knows how many, I would recommend you take his advise. Invest in a vbox and take some logs for experts to see. Otherwise sometimes you'll learn that if you play with fire, you're bound to get burned.

With the proper belt size car has ZERO slip. Boost curve is perfect. Dyno shows zero evidence of a timing issue. Matheo will be running a log to show timing. You can see right away if timing is pulled or if there is an issue. I am curious as to how many non vendors in this thread have actual experience with what they are talking about, and how many are just regurgitating what they have heard. |

My advice would be to be very careful putting 9+ psi on this motor and to expect the worst and hope for the best if you are set on running it this way. |

You are making over 600 whp on a VT2 625 kit. This is well above the designed power for that kit. If you want higher boost I would run a 650 map at the very least and I totally disagree with your 82mm pulley theory. I had slip issues on 88 sometimes. Its more intelligent to run the 650 crank and larger pulley. I would say that Roman knows what he is talking about since its his companies product you have. Why you want to experiment with a kit that ESS has logged mountains of their own data and experience is silly. Have a talk with ESS and have a private discussion with how you want to customize what you have safely |

Regardless, I would personally hire a specialst such as an aeronautics engineer specializing in turbo prop or other FI airplane internal combustion engines to work directly with ESS before I did anything like this BECAUSE OF altitude. Maybe AR Design has such training.

Yea, I just spoke with Andrew @ Active and discussed a few things and he passed some great insight my way.

Not really posted here for obvious reasons but this really warrants a little back up from another company which supercharges multiple platforms. I would take what Roman is saying very very seriously here. |

The car is putting out a little over 500whp uncorrected. I still don't see what all the fuss is about. It runs perfectly, no issues, whatsoever - and it is run HARD.
Regardless, we are about to do a custom re-tune for E85. So it will be a moot point. I'll do another pull on pump gas and post it up so people can see. As for the smaller pulley, with the correctly sized belt, we are seeing zero slippage. Would there be any interest in an upgraded fueling/E85 tune/supercharger pulley package? |

I personally don't think its fair to use corrected for density altitude on a FI car at altitude since the SC compensates for that in absolute boost. I missed that it was compensated at a quick glance. personally 500 wp is not great for 9psi actual boost. I was running well over 540 uncorrected with 7, 8psi on my custom crank and pulley set up at 5500 ft Something isn't right |
