More ebay 20g drag passes
Trolled by mother nature. I thought plugging in my o2 sensor might make a difference. Scarily that's not how things worked out. My fuel trims are all jacked up with or without it. Airflow counts are down. I have more to do to this thing, but in an effort to keep things real, I'm uploading what happened and what I found in the logs. The PRIMARY reason for racing is development of both self and your equipment. If your goal is to have an awesome street car, you can't fully-achieve that goal without rigorous testing where numbers and facts are clearly evident. You JUST CAN'T do that on the STREET. There are no numbers on the street, no measurement of a baseline nor any improvements you might make. There's no measurement of a drivers' skill outside of, "did you win or didn't you?" I didn't come to the track with the expectation of MY driving needing to be improved. I was simply getting numbers, so I wasn't a tree-nazi like I was in the Friday Night No-Lift-To-Shift video. There was more incentive for me to just not red-light and see what she'll do. This evening I didn't feel like the track crew were on their A-game. Sometimes they held staged cars for an inordinately long period of time... which once I'm staged, I'm on the rev limiter, and once they left me there awaiting the tree for over 20 seconds, heating my car up and leaving me disadvantaged out of the hole. Other times they treated the starting lanes, dried off my opponent's side but not mine, not giving instruction to hold or wait. In fact, one guy was signaling me forward while another crew member was standing in front of my car spraying the lane. What do you expect for only $15? I'm grateful for them, but the communication could stand improvement over what I saw tonight. Perhaps I'm just a bit miffed with my setup and looking for someone else to blame? The track officials certainly don't deserve any for how it ran this night.
First ebay 20g drag passes
I made 2 passes. On the first one, nearly everything that could go wrong did. But I'm a persistent bastard. I fixed it all, found everybody and then made this run. It wasn't until after I got home that I realized I had no in-car video footage of the first run when I broke despite having set it up... I kicked the alternator belt off no-lift-to-shifting into 4th gear around 800 feet and coasted to a 13.3 at 82mph against a 10 second Mustang. Overheating with no power steering I limped it back and put the belt back on, only burning myself 9 times, and then got back out and made this run. The guys in front of us broke, too. I guess it was contagious? This run is on 93 octane pump gas. I shouldn't have been in such a hurry. It left me a little unprepared. You learn things about other things while doing things--is the best I can explain it. It didn't knock at all, so clearly the new injectors are working fine... but I didn't take time to burp the coolant system, so it ran hot. My alternator belt was loose, and it bailed on me. I was focusing on explaining the video (I deleted that scene from frustration) rather than putting the car back together, and failed to plug in a very important sensor. I would have caught it, but didn't get a chance to look at the logs until I got home. I have to operate so many pieces of equipment in addition to actually driving that it's very distracting. The guy in my second race had a beautiful 1967 Dodge Dart, and he was a very good sport! It was a great race where adrenaline is involved, and I was focused but wary of whether or not the alternator belt would stay on. I really appreciate the guys that keep old muscle alive. That car's almost 50 years old. That's making history right there... He cut a great 60 foot after they cleaned up the track, but I wish that car didn't break in his lane prior to his pass if it was a problem for his run. I tried to leave nothing out and keep it short & sweet. I was lucky to have a track-side cameraman for the second race. Thanks Taylor! Having that sensor plugged in would have left me much more confident in the log data and offer a much better assessment of this turbo, but it is what it is. Here it is...
Cylinder Head 204 - Porting & Polishing
This is a first-generation 1992 1.6L Hyundai Elantra small-combustion-chamber head. Thats what it is. It's a J1 Elantra cylinder head. Good luck finding another one like it. (read more)... In Cylinder Head 106 I talked about the mainstream porting theories as they are discussed. We looked at a cylinder head that I have thousands of dollars of professional work performed on, and a bone-stock second-generation head that I didn't port. In this video I just might do something you haven't seen done before. For some, that may be uncomfortable. The port and polish job I perform here is what I think will work best for my current build. This is not an extreme killer port job. What will be different here is where port textures are concerned, I will be following the advice of a reputable source that will remain un-named. You're free to port yours differently than I do in this video, and I give you that out, around the 20 minute marker. The Hyundai is far from being an ultimate-performance build. It's a $400 box of scraps with nothing but time invested. It's perfect for this video. My finished product WILL be an improvement over what I had. I don't yet have access to a flow bench. I still have an achievement to un-lock. As far as you should be concerned with the techniques I employ... without flow numbers there is no evidence of what this will do, but we will gather lots of info from dynp sessions and drag strip time slips. If I could test it on a flow bench, I would. There are MANY, and when I say many, I mean thousands of flame war mongering pirates floating around on rough seas with a hair trigger cannon finger itching to fire if you port a head any differently than what the herd mentality says to do while porting a cylinder head. I cover the herd mentality because it has merit. It's been tested. Tried and true. But I don't follow it to the letter of the law. I'm definitely not here to de-bunk it. I would port a cylinder head differently for each build based on how that engine was used. There's an extremely valid reason why relating to air speed. It's not the texture of a port that maximizes the effect of fuel atomization, but the velocity of the air running through an x or y sized valve. The driving factor in this is the piston speed. I'm not going to give you the technical information, but will refer you to information about the Lovell factor. There's a better description of this in the links below, and even a calculator to help you find your engine's sweet spot. Why the Lovell factor is important: https://www.highpowermedia.com/blog/3346/the-effect-of-valve-size Lovell gas factor calculator: http://www.rbracing-rsr.com/lovellgascalc.html Only people who have flow testing equipment know for sure what really works and have the capability to produce a perfectly-matched port job for the ultimate performance build. Those guys know the definition of ultimate, and THEY are floating below the water Aegis-class submarines ready to blow your comment up if you don't know what you're talking about. They don't care if you're an armchair mechanic or a herd of pirates. I will say, they're zoomed in pretty close on me right now, and I'm expecting to take a few hits. My work will be tested based on Dyno and drag strip performance, and the results will be posted here. Fortunately, those kinds of videos are a WHOLE LOT EASIER TO MAKE!!!
CRANKWALKED? 7-bolt teardown 1080HD
Now this is a story all about how My bearings got flipped-turned upside down And I'd like to take a minute just sit right there And tell you how I used to mix and burn my gas and my air. In RVA suburbs born and raised On the dragstrip is where I spent most of my days Chillin out, maxin, relaxing all cool, 'n all shooting some BS outside with my tools When a couple of guys who were up to no good Started running races in my neighborhood I heard one little knock and my rods got scared And said "You put it in the garage until you figure out where..." I Begged and pleaded that it not be that way, But it didn't want to start and run another day. I kissed it goodbye, because the motor punched its ticket I got out my camera, said "I might as well kick it." Crankwalk yo this is bad Drinking metal shavings from an oil pan. Is this what the rumor of crankwalk is like? Hmm this won't be alright But wait I heard knocking, grinding and all that Is this the type of failure that should happen to this cool cat? I don't think so, I'll see when I get there I hope they're prepared for this video I share. Well I pulled all the bolts and when I came out There were chunks in my fluids in the pan and they drained out I aint all depressed cause I seen this before. I got my books and my wrench and we'll do it once more. I sprang into action like lightning disassembled I whistled while I worked and my hands never trembled If anything you could say that this bling is rare, and when I saw what broke I stained my underwear. I turned off the air compressor 'bout 7 or 8 And I yelled to crankcase "Yo holmes, smell ya later" I looked at my internals they were finally there To sit on my workbench and stink up the air. Audio track by RojoDelChocolate. Here's the 48,000 mile-old 7-bolt I blew up summer 2011 after over 150 drag passes, a half dozen Dyno sessions, 4 transmissions, 3 clutches and 10 years of hard all-weather use.
