    My 3rd meeting with Outlaw Street and another big improvement in ET, MPH and RT throughout the day.

    Still got a bit of tuning to do, but running much better now.

    Finally getting somewhere with the dial in on my LQ9 motor. Still having traction issues off the line, but I am on street tyres with leaf springs...

    1.7750 60'
    7.824@88.88 1/8 mile
    12.2478@111.38 1/4 mile

    Over the course of the day I improved from 13.1 to 12.44 and 108 to 111. The first run in the 13's was on cold tires and I got about 20yds of wheel spin.

    I was having trouble getting in the 12's on my last outing, since then I have:
    Replaced the exhaust from the headers back with a Pypes SG13R system with race pro mufflers. This replaced a 2.5" system with chambered mufflers.

    I also noticed it was leaning out a bit at the top end of the track, only up to around 13.2 but it wouldn't have been helping. I couldn't tune it out so I cleaned all my filters, replaced my fuel pump and return line and now my AFR is perfect at 12.7 all the way through.

    Today I did 6 runs, each time increasing the ignition timing 1 degree from 25deg to 30deg. 30 seems to be the sweet spot for my motor taking it from 108 to 111.38mph. I went as far as 31 and the MPH dropped back to 110.9 so I pulled that 1 deg back out.

    I'm running on the best pump gas available in the UK, Shell V Power Nitro+

    So, with the modifications in my signature is this about what I should expect from the motor?

    Screw that, that is a huge ass jump, I would be flying high and not even think about N2O!!!
    Keep plugging away at the little things and have fun.
    N2O is a pain in the ass, and once you get started, it's a frigging slippery slope!!!!

    I'm still missing a few MPH from where I should be. So I'm going to keep on tuning to see if I can squeeze a bit more out of it.

    Considering swapping to a single plane intake and 1200cfm throttle body. My cam grind suits that intake style, but it also means I can get true cold air into the intake by using the scoop in my hood :)

    Worth a shot?

    Can you find some 100-102 fuel there???
    That might give you a touch more HP potential.
    110 would more then likely be a waste of time.
