    Well for now the UPR Boostmaster cold sir kit I put on yesterday has dropped the inlet temps 25*. Went to track yesterday and only seen 175* vs 200* prior. Not great but definitely going the right direction now.


    Speaking of going to the track..... didnt have a very good day. Had to abort 6 out of 7 passes due to it going dead lean when I shifted to second gear. Only pass I got down the track under any kind of power I left real soft with a 2.14 60ft then shifted slow and easy. Once I was in 3rd I went WOT to 5500 then easy shift to 4th and WOT again. Ran a 13.20 but timing system didnt show my MPH. Found I have a bad connection in the harness plug going to the injectors. If I wiggled the plug the car would shut off or stumble just idling. Looks like the G-forces on 1-2 shift was enough to break the connection and the injectors would shut off. Every log I took showed 8-9 psi in 1st gear and 11.5 afr....shift to 2nd and it would go 18.0-1 faster than I could get out of it.

    Had a much better track day last weekend! Details in my thread here:
    http://www.foxtbirdcougarforums.com/...aking-progress!

    Picked up a set of CHE adjustable uppers and now I have full set of Welds to lighten it up for next try at the track in two weeks. I think Im going to meet my 11.99 goal pretty soon.

    Well leaving work last week I got after it a little harder than normal and the T5 finally let go. Looks like I blew out third gear. Cant really be mad since this motor is making at least 460ish at the flywheel now so it is what it is. I just ordered a G-Force T5 with the 2.94 1st gear box and .59 OD and this will allow me to change out the 3.55s in the 8.8 for some 3.90 gears. This combo should put the car in the 11s solid and on the expressway my cruise rpm at 70mph is only going to increase 175rpm.

    I think you'll be really happy with the G force. If I ever upgrade my Maverick, that is the direction I'm going.

    Big week ahead!

    My new G Force will be here later tonite and I will be installing it in the morning. Im swapping out the 3.55s for some 3.73s right now. After the trans is in tomorrow im pulling the dash to replace my blown heater core, putting new dash pad in, moving the air temp sensor and installing some 60lb injectors.
    Then I will have about 4 days to get the clutch broke in and retune. On friday Im loading up to head back down to Norwalk Summit Motorsports Park for the weekend to run True Street again at the NMCA race. Saturday I need to find as close to a 12.000 tune as I can if I want to try and win some money in TS. Come Sunday I will be running the bracket class and I can let it all hang out and see what it has in it. Really hoping I can squeeze a 11.70@118 if things go the way I hope.

    Well another race weekend in the books!

    To back up to last Thursday I really didnt like the 373 gear with the G-Force t5. First gear was still to tall and 5th was useless around town. It cruised 2200 rpm at 80mph and 45mph was 1000! I ened up putting a 3.90 gear in on thursday and it felt much better.

    Sooo, Norwalk Ohio NMCA True Street on Sat morn.......Somehow by 10am they were running 4hrs behind schedule. TS was to get a time trial at 10am but we didnt get our first run until 2pm. Made for a very aggravating day because I felt like I had to hang around my pit area in fear Id miss our call if I wandered off to other parts of the track and didnt make it to staging in time.
    When they called us up at 2 I grabbed my laptop and got in the lanes. I turned on datalogging and made my first pass. Did my normal 3000 rpm launch and the car dead hooked and fell on its face. After it recovered it felt lazy and I knew the run was slow. It ran a 1.82 12.82@108. After I checked the log it clearly showed blower belt slipping again. It peaked at 7psi at top of first gear then after that never went above 5.2psi rest of the run. Quick check under hood showed the belt was very loose from stretch and from my Carbinite coated pulley chewing up the belt. With no extra belt on me and no time to go buy a new one I just tightened the hell out of it and got in line for the TS cruise.

    We did the 30 mile cruise without issue and got in line for first pass. Didnt know what to except on my first run so I left at 2500 slipping the clutch just a bit and it ran a 1.70 12.14@116 BAM, new best mph!

    Second pass the guy i was racing screwed up my routine by taking like a full minute just to go from pre-stage to full staged. I was holding car at 3000rpm for what felt like forever when I let off the gas to look over to see wtf he was waiting for when he finally bumped in and tree came down before I collected myself again and I ended up dumping the clutch at like 2000rpm and car bogged and almost stalled out. Run was only a 12.50@113. Right there killed my shot at winning the 12.00 class.

    Final run was after waiting an hour for an oil down so car cooled off pretty good. I left at 3000 nice and easy and pulled a 1.61 12.07@115.3 Not the 11 I wanted but still a new best ET. I think my 5800 shifting is what held it back this time.

    I stayed for Sunday bracket race to see if I could squeeze that 11 out of it but it wasnt meant to be. Since you cant have laptops in the vehicle during TS i wasnt able to get any data from the previous 3 runs so I plugged in for my first run Sunday. I tried a 3500 launch and it dead hooked and fell on its face! Rest of the run felt down on power and it only ran a 12.62@112. Looking at the log it showed belt slip again with only 4psi in first 3 gears and it peaked at 8psi for a split sec in 4th before dropping again. I checked the belt and its chewed up good now so I called it a day and packed up.


    Im going to add some Strange 10 way adjustables in place of my KYB's and hook up my Launch Control in the Microsquirt to fine tune my launch technique. I still havent tried using my Snow meth kit again yet so I have that to play with as well. I have two more track days coming up on the 14th and the 30th
