    Hissed Off - Nitro SE Drag Car

    Here's another hit, against a .21 big block car. Crazy how the car re-wheelies when I hit the nitrous, but it's clear the wheelie car is too low, cars needs to squat more instead of bang so hard like that. Gotta soften the suspension slightly too. Looks like 2.5 seconds going by video. Not...

    Hissed Off - Nitro SE Drag Car

    At our first TnT this car was probably the most consistent, fast car of the day. Made some really fast passes right out of the gate. Tree was down (thanks to a faulty power strip) so no official times. But, looking at the various videos, it was running 2.4-2.6 most runs. It was running...

    Well, I'm glad it won now, because it will not look nearly as good in a month or so :D

    Hissed Off - Nitro SE Drag Car

    64 degrees on Sunday, so I took the car and spent a couple of hours testing and getting the shift point dialed in. earlier in the morning I swapped out the (very) heavy Integy shock towers for CF. That was a 70g weight drop. I didn't weigh the car, but based on last time, that puts it under 5...

    Hissed Off - Nitro SE Drag Car

    I finally had a "semi" warm day to test (48 deg). I had the 18/58 setup and the new Team Orion pipe installed. Did some all-motor passes first, and these changes combined with the motor getting a little looser (I recently learned that this particular engine is a MF to break in apparently...

    Hissed Off - Nitro SE Drag Car

    We had temps close to 50 both days this weekend, so I packed up the car and took it to my favorite practice spot to finish the break-in. Used an engine warmer to keep the engine temps up. Saturday the engine was still tight as hell (very typical of every OS engine I've ever owned). It was...

    Hissed Off - Nitro SE Drag Car

    Well, it's done :) Other than I have another pipe and clutch bell coming in that I will test out vs the stuff in there now. I got the ProLine Frontrunners for the front, and used a chrome pen to make them look alloy, and put some white lettering on the tires. This wound up shaving it down to...

    Hissed Off - Nitro SE Drag Car

    Got the break-in started. Eventually got it out in the driveway doing some little short bursts. Power feels good so far. Sounds really nice. Got my new header and pipe coming today, so next time I'll run it with that. Replaced the rear arms with plastic and re-weighed. Down to 5.1 on the...

    Hissed Off - Nitro SE Drag Car

    This new engine is a .12, so I'm dropping down in size from the .21 in fact. The .21 has 5 ports, the .12 has 3 (I think that's the case for all .12 engines). OS rates the .21 tm at 1.77 hp, and the T1204 at 1.73 hp, so very similar in power, but the T1204 can go to 45k vs 35k for the .21 tm...

    Hissed Off - Nitro SE Drag Car

    Got the T1204 in. PITA. Just cannot understand why engine manufacturers are not consistent with their drive shaft lengths. A little shimming at least got the spur off of the bell housing, but I'm only able to get about 2/3 of a mesh alignment. The issue is that the threading on the shaft is...

    Hissed Off - Nitro SE Drag Car

    I got my new shocks, and these things are sweet. Say what you will about Integy, but I have found that their shocks are very well made and hold up great, never had them leak. These are a decent bit lighter than the previous monster sized things I had on there. Had to shorten the travel on...

    Hissed Off - Nitro SE Drag Car

    Thanks! I use a corner weight system to get precise measurements. Getting it really balanced isn't easy. I'm mostly concerned about front-rear, and the rear corners. Generally the nitro builds are pretty even in the rear. The area they aren't great in is front-rear. For that, I like to put...

    Hissed Off - Nitro SE Drag Car

    Nearly done with the body. Wound up slapping nitrous in this thing :D New shocks on the way. Weighed the car, it's at 4.99 lbs, so down from 5.5 or 5.6 lbs last season.

    Hissed Off - Nitro SE Drag Car

    Just a 3018 one at Amazon. I just use that for smaller stuff and prototypes. The chassis I farm out to a place called CNC Madness, they do it cheaper than I can buy the CF for, and it's precision laser cut.

    Hissed Off - Nitro SE Drag Car

    Been a long time since I did anything to this car, other than change the body. I pretty much kept it the same for 2 years, and the car never ran faster than 2.8, but then again, never any slower than that either - super consistent. Despite it not being the fastest car, it won the season list...

    Hissed Off - Nitro SE Drag Car

    About a week ago I saw someone selling a brand new Ofna Viper body, which was something I'd searched for last year when considering going to a Viper for Invader. The wheel base was right, and though the body isn't perfectly scaled I figured it would still be cool to get. The ones I'd found...

    Yeah, the front ends are required by rule to have shocks, etc, and they do run much smoother than pan car style fronts. Lighter is not necessarily faster. My fastest car is also my heaviest.

    Hissed Off - Nitro SE Drag Car

    I replaced the shocks with the same kind that I am using on Incinerator, that are big, big bore and much better to adjust - plus only 30 dollars for the full set. They aren't quite as good as the Integy ones I use on Invader, but they'll do just fine. Got it balanced on the corner weight...

    Hissed Off - Nitro SE Drag Car

    Car got it's initial runs. Had some concerns when warming up, the car was spinning badly, like a top, and at one point it did a corkscrew cartwheel (nothing got hurt thank god). I made six or seven passes, and the car actually ran straight and true. I recorded a couple of 2.8s runs. A...

    Designed some shock towers. Considering 3d printing the bulkheads as well for the chassis' I sell.
