A&A - standing mile, any fuel or cooling issues I should anticipate?
Another winter another upgrade. Currently at 433/396 with Heads (Stg 2.5 317’s), cam (226/228 .600 114Lsa), ported FAST 90/90, 1 7/8” ARH catless. Decided to go with A&A basic kit, which I believes comes with Boost-a-pump for 2003+ C5’s. It will be installed by a very reputable corvette shop who’s done many of these installs, so I’m not worried about having everything done right. I don’t track or drag race, mostly just a weekend canyon carver but occasionally I enjoy running Standing Mile events to see how fast I can go! My question is about standing mile events because someone told me I will have fuel delivery and temperature issues with supercharger on long pulls like standing mile. I think this person has had issues on his supercharged C6Z and is just trying to scare/“warn” me but he is way more experienced than me so thought I’d post this here! thanks for any info!! heres a video one of my slower runs at Colorado Mile 2017 on setup I have now |
maybe run meth to help keep iats cool on long pulls and add some extra octane... e85 would be even better if you have that around you and don't mind building a fuel system
|
Just don't run with 1/4 or less fuel in the tank.
Otherwise if tuned properly it will be fine and especially if final WOT run has been done with a proper long pull, not just 5 secs or so.. |

Running below a 1/4 tank leaves chance for fuel to slosh away from the bucket andcavitate the pump, as well as possible heat issues for the pump. Add a meth kit to keep iat down on long pulls and have fun. |
I never knew any of this so my idea of a sc has ended...what's the fun in worrying about heat and gas issues within a single mile run...maybe i am missing something here but it sounds like you need to be extra careful with a sc and I am not talking about handling the power...please convince me otherwise because i really wanted one...
sorry to hijack post....i was just taken back by this.. |
You should be fine, the a&a kits have a nice front mount setup and ducting to force air in. A good tune will put you in a safe range for a mile event.

well I’ve pretty much committed to this now so if standing mile is too risky I can always switch to HALF MILE instead. When I ran standing mile in my current setup it took me that long to get to 160-165. With A&A setup I should be able to hit those speeds in HALF MILE. I guess I have a lot to learn about this stuff yet and will keep researching and will also talk to my tuner about what to expect, look out for, and consider for these types of events! |

Just make sure the tune is good. Mile runs require over 10 seconds of wot in 5th gear. The tune needs to be perfect. I have run 20 plus runs over 200 at the Texas Mile, no issues. A&A kit, Nitrous and Meth.
Build it, tune it safe and have fun. |

Which kit do you have? A&A or ECS? This is one that I keep going back and forth on...
|
go with a&a, much better quality and customer service
|
I am going with A&A for sure, the shop doing the install has done a lot of the A&A kits and suggests them! |
You are definitely going to want some some sort of data logger. Tuner can get a safe setup on the dyno, but actual data from a 1 mile pass in invaluable.
Basic wideband O2 fed into EfiLive or HP Tuners will work. You wont need in-depth tuning knowledge, just enough to pull the log and make sure nothing goes out of range. From there the tuner can earn his $$ |

is that something easy to set up myself? I don’t have any tuner software or knowledge so unless it’s something I can do fairly easily or have my shop install for me. Your tuner should be able to set you up so all you have to do is pull the SD card out of the box after a run and look at no more than 10 parameters for safety on a laptop... Save him some files for tuning later, and you will be good to go. The entire process at the track can be done with a simple checklist, no tuning knowledge required. |

If the car survives a real hard dyno pull and the data logging looks good, I would not hesitate. |
