before the IATs cruising were 1-2 degrees above ambient cruising, and right around 115-118 by the end of the 1/4 mile depending on the air temp of course. The new filter 1-3 degrees above ambient cruising and my last day at the track it was 46-51 and the highest in saw was 95 that day. I think the intercooler is doing a good job and making it so it didn't effect the performance and IATs.

I tried with traction control on once in 2wd and it didn't feel super invasive. Out of all the differant launches I've tried 4wd hi with about 1500 rpm stalled and hitting it on green have been my best times so far.

Gorske, if you’re going to be running alcohol like that supercharged you should seriously considering logging the data. Making the power to run 12.4 on alcohol your stock fuel system must be on the ragged edge and you run the risk of losing a/f ratio control. That story may not be fun to tell.

Thanks for the reply. I’m definitely not trying to get in your business but.....you must be making 550-575 rwhp which is close to the limit I see quoted for the stock fuel system. Even if the injectors are capable the rest of the fuel supply system may not be. It should just be a matter of adding low fuel pressure to your log. My tuner said he starts getting concerned at around 45 psig on the low pressure side. He’s a conservative guy but with lots of experience. If your injector performance is okay, as it looks, the hp side should be okay. If the low pressure pump can’t provide adequate feed to the high pressure I believe you could get a rapid increase in a/f ratio. Not sure exactly the consequences but it doesn’t sound good. And running higher alcohol taxes the system further as the flow rate is higher.
My credit is great so I don’t have to worry about funds for all the truck goodies and auxiliary stuff. Just get to pay for it for the next few years. Ha
PS A dyno run would be fun and informative, eh? But the cost is about the same as getting set up with Hptuners.

So unfortunately no track for me today, just way too much stuff do so it’ll have to wait until next year. I will say, I had reservations about going with a centri setup over a PD but there is zero compromise with this kit, it drives so nice, really just like stock and mileage is the same as stock as well, obviously that all changes once you put your foot in it.

Yes sir. Truck is all stock except for the ProCharger tuner kit for my truck(which uses the stock fuel system), Circle D 278mm 3200, stall, Klug Performance tune, and a custom cat-back with the stock manifolds and cats.
