What about the sump pick-up issues when driven on R compunds around a track?

For 400-500 HP, there arent really any more issues. Yes, if youre thinking ceramic turbos but i know youre a smart cookie and wouldnt do that :)

For longevity, make sure you have good oil and at a good temperature before you give it stick....look after those bearings!

I would imagine std rods would be getting to their limit at that stage....if not rods then rod bolts for sure.

Wait a sec, are you talking engine hp or at the wheels? Engine hp should be fine....at the wheels then you would be getting close, probably same for pistons. Im talking more along the lines of the 500hp target.

      The best part of my setup is, we only have two sites. Our head office where I'd put every thing has plenty of internet capacity. We're on a 200/200 dedicated fibre. Even better, there's only like 6 people in the office at most, and the other office has 2 people in it (likely 3 soon). The majority of our work is in a custom piece of software, as it is part of the backend of the system we provide to customers. For our arrangement, on prem would be wayyyyy easier, and a VPN tunnel site to site is easy for me to manage. Scaled at many many sites, or quite a few hundred employees it's starts getting a bit different for all people outside the head office. However, everything in the cloud becomes worse for the people who operated previously at the site that held the servers, as now they're at the mercy of their internet, and not GBPS internal network (f**k the idiots who hook a desktop PC up on WiFi or permanently sit at a desk using a laptop and don't go remotely with it).   It really does come down to the business needs and structure as to what is best. For us, 365 is mainly being moved to for office apps, moving email from Google to Exchange, and setting up "Active directory". Otherwise we have a ticketing system with support that runs on our own cloud system, or the sales process sits in a CRM we pay for. My biggest push back for having most of the shit turned off and saying no when people want new shiney things is "that won't meet our security requirements, or efficiency gains, so all you're requesting is money spend to open us up to security issues, or to make our staff less efficient" Which is funny when one of our core values is "To do more, with less"

      Think of it as a fancy iFrame with the auth passed through to PowerBI as you're already authenticated logged into Teams   I'm the complete opposite, I hate everything on Prem, it's slow as shit, you need VPNs to get anything happening, then when you want on-prem DBs to talk to say PowerBI you need to install/setup data gateways to essentially VPN back into your SQL instance. I suppose from my perspective, on-prem sucks, but from an infrastructure perspective, your environment is somewhat air gapped to the web via your firewall(s), etc.   The curse of knowledge, the more you know the more you suffer. Farken philosophical shit.

      Haltech Iat Vs. Oem Iat Rb26 ?

      By ggub · Posted

      Wherever you ask them to. I had one added to the crossover pipe near the BOV as well as the hot and cold sides of the intercooler piping to provide greatest flexibility in measuring temperatures post-turbo. I have the IAT installed in one, and bungs in the other two.
