So here I am just enjoying all 116 hp the 1.6 has to offer and you need more! This is wild. I think I would be terrified to be in this thing.

  Done for the day. Not bad for a few hours' work. This car is super easy to work on. Button it up tomorrow. |

Had a doh moment today. Car was idling odd since the new heads, and figured it was the tune being a little off. Get it on the dyno, and it's missing 80-100hp. We found 40hp or so, but it wasn't right.  I totally forgot to change pushrods for the new heads, which are shorter, and require shorter pushrods. The rods that were in it were so long, the valves couldn't close all the way, thus a bad idle, no compression, no power. Doh moment. Huge waste of a day, time, gas, money, etc. New pushrods in the mail... will try this again. |

I think we have all had one of those moments. I love the car, its one of my personal favorite race chassis.

Can't deny doing that same thing once...

Wrench long enough you will have a kick yourself in the ass moment or two.

Good judgement comes from experience, experience comes from bad judgement. I just look at it as something I'll never do again.. I've learned a lot this way!

Fresh correct sized pushrods and matched injectors in, this thing is officially retarded fast. I may have to rethink my plans to build a new engine for it, it's about perfect now.

I saw that you did your own alignment. Roughly how much camber are you running? The guys that set myne are used to miatas and gave me too much, 5.5 degrees. The inside of the tires are hot while the outsides show no wear or heat. Running about 20psi. Love seeing somebody else competing in Autox. I was the fastest car on street tires, only 1 second off ftd, still fighting a few issues.

5.5 degrees, holy crap. I started around 3.8 (which was way too much), right now it's about 2.5 in the front and 2 in the rear, and perfect wear/pyro readings. 550#F/336#R springs with a large front bar
I run 27f/29r in the hoosiers, and 22psi all around on the street tires.
These cars have such low CG/roll center coupled with the stiffness of the chassis and negative wheel offset that they don't lean nearly as much as a miata, and dont need nearly the camber to work.

Did some bump stop trimming to get some more usable travel in the front before sitting on the stops. Don't recommend this if you aren't on at least 500# springs. The goal is to keep it off the stops in short transitions and slaloms and let the springs do all the work (it will still sit on them in max G long corners, as it should)   |

I think that depends a lot on the suspension. On stock springs, ours rolled a LOT - it picked the inside front tire up well off the ground in slaloms and the outside tire hit the headlight mount. It's much better on Vmaxx coilovers. Thanks for the camber numbers, ours gets aligned and corner weighted next week. |

Of course it's dependant on spring rate, but compared to an equally sprung miata, is what I meant. Another good weekend of AutoX, finished 2nd again today, this time FTD went to my good friend Radlee in his FM Dwarf sprinter, certainly a cool car to watch. Wasn't a very open high power course. There was a LARGE figure 8, and I can say with 100% certainty that the hydramat fixed all the fuel stave issues. I feel the bump stop was a positive change, now am going to cut the rear bumps by 1/3 to match the fronts. The limitation of the car now is certainly the terrible brakes. It has mystery pads on it, probably cheapo ceramic pads up front, since they dont dust at all. It doesnt have any bite, and stops poorly. The fix is going to be some radial mount wilwoods, with the side benefit of saving 18 pounds of unsprung off the front corners. I feel its critical to address this now, since I have a date on the real road course less then a month away, plus divisional race at the end of the month. Oh, and the drag tires came in today. 26x10.50 et street Rs. They're sofffffffffffft.  |

For comparison's sake, this is kind of funny. Believe it or not the wheel/tire on the left is almost 7 pounds lighter then the right.  |
