Greddy Turbo Questions thread....
I had my first bout with cooling issues today. Spirited boosting on the freeway this afternoon, since it was cooler today than it was last week. Suddenly, I hit some traffic so I was sitting still for a spell. I noticed that my seatbelt indicator light came on and thought, "herm, that's odd", since I had my seat belt buckled. I thought it was a faulty seat belt sensor until I looked up a little further (AP2) and noticed that my ECT's were two bars past normal operating temps. I have the Modifry's patch for the AEM EMS so my temps read norm at the halfway mark. At this point, I was two bars passed that. Whoopsie!
I pulled over and rested at idle for a moment, parked in front of a little cafe and shut her down under a tree where it was nice and cool. When I came back from lunch, everything was honkie-dorie. WHEW! Won't be doing that again any time soon.

LOL! If there's one thing I'll say about the Modifry patch, it's brutally honest. I just took her out for another drive and she's behaving normally. I guess I just got caught boosting at the wrong time.
I believe 2 bars on the AP2 is similar to 1 extra bar on an AP1. In the middle of summer when my car was stock, sitting in bumper to bumper traffic with the AC on, I sometimes would hit 4 bars (3 is normal.) Nothing every happened to the car. As a safety feature, on an AP1, your AC will shut off until the car goes back to 3 bars.
OK, so i have to comment on what i previously stated about my boost dropping when i switched from an 80mm catback to a 70mm catback.
Turns out this was untrue!
Once i swapped the 70mm in, i thought i had seen more boost w/ the 80mm, but my memory failed me. I swapped the 80mm back on today, and turns out, i actually hit less boost than i did with the 70mm!! BUT i'm guessing that this is because i was actually tuned on the 80mm and NOT on the 70mm so i was seeing more spiking. On the 70mm I was spiking about 1 psi more than the 80mm. So i'm thinking that the 70mm is big enough for at least 300whp, i just need to get my car tuned on the 70mm to run optimally.
This is good news, because i thought i was giving up some power in order to run a quieter exhaust, however, i can probably still hit 300whp with the 70mm, just need to tune with it. =)
