Title: Spacer selection Post by imracin68j on 03/21/11 at 1:11pm Anyone dynod spacers before. Not really looking for random opinions as I know that you get more torque with a smaller spacer but has anyone tested or played around with spacer styles or heights and seen gains one way or the other. The 3 main styles seem to be open, 4 holes, or tapered holes. By the looks of it it would seem that a tapered hole might flow more but how much, i'm not sure. I'm looking for someone with real dyno experience on spacers. We need more tech in LMR. |

Title: Re: Spaced out on Spacers Post by hogracer3d on 03/21/11 at 1:25pm the guy at VDL, doesn't seem to fond of spacers it seems, but we tried a custom late 90's era 2"one hole from Ron Hornaday's Super Truck, and it made 14hp over no spacer at all, but was 4hp less that a 4 hole 2" Super Sucker |

Title: Re: Spaced out on Spacers Post by imracin68j on 03/21/11 at 1:31pm They make some pretty wild claims on the tapered stuff. Seems like it would be somewhere in between? I gotta get my air cleaner out of the oven. lol They don't come much prettier than this. http://www.shopatron.com/products/productdetail/part_number=3215/1526.0?utm_source=google&utm_medium=shopping&utm_campaign=googleshopping |

Title: Re: Spaced out on Spacers Post by Sparky56 on 03/21/11 at 5:46pm Billy, you worry more about little BS stuff. Get a tapered 4 hole 1" pholnolic spacer and call it good. Marop says.......... |

Title: Re: Spaced out on Spacers Post by imracin68j on 03/21/11 at 7:46pm That attitude is the difference between a 16.2 lap and a 16.5 at sms. This board lacks compared to 4m.net when it comes to tech. Frankly, I'm sick of heading over there for tech. It needs more real tech topics that racers can use. btw, you need to worry more about getting your car done rather than policing my posts so I can woop dat azz at SMS. |

Title: Re: Spaced out on Spacers Post by Sparky56 on 03/22/11 at 9:01am You need to finish a race before you try to woop-azz. |

Title: Re: Spaced out on Spacers Post by SawyerRacing98 on 03/22/11 at 11:32am Lol. Im with joey. If you think a spacer is going to make a difference between winning and losing you're crazy. |

Title: Re: Spaced out on Spacers Post by imracin68j on 03/22/11 at 12:48pm lose the tech section on LMR. It's worthless. Trying to create tech threads similar to 4m.net is pointless on lmr. Instead we get worthless posts of what does it matter. If you want good tech 4m.net is the place. I could care less about posting any more tech topics here. Sparky, after reading about your 5 degree pinion angle suggestion my first thought is you should be trying to absorb any kind of tech you can get. lol |

Title: Re: Spacer selection Post by Sparky56 on 03/22/11 at 3:46pm more in the shop + less time on here = faster car. I forgot more then you ever learned.......... |

Title: Re: Spacer selection Post by SawyerRacing98 on 03/22/11 at 6:16pm And tonights winner in the #68 car billy simkins!!!! "Yeah I couldn't have done this without my new over priced carb spacer, it really directed the air so perfectly into my motor and is the reason I won tonight!" Lol yuuuuup I can hear it now. |

Title: Re: Spacer selection Post by imracin68j on 03/22/11 at 6:25pm Why I'm going to explain this is beyond me but here we go. My aircleaner hitting my distributer which is sending an arc into the base. I also run my body up higher than everyone which sucks a lot heat into the carb. So, the obvious solution is buying a 2 inch carb adapter. Since I had to get one, I thought I'd post up a tech thread on spacers. Then you and your sister show up and drop useless information. lol I'll take Daves information and drop a super sucker style on it. What ever Sparky chooses I'm doing the opposite as I'm not into losing 2/10ths. lol Waste of key strokes. |

Title: Re: Spacer selection Post by SawyerRacing98 on 03/22/11 at 6:41pm Okay ill be more serious... I have ran a few different styles but never done dyno time with them. But to be completely honest I think that a one inch spacer wide open without holes would make the most power because you have less restriction. Also I do know when I ran at irwindale there was a team that gained 4 hp from going from an all thread type carburetor stud to a smooth stud. Now with that said I think the less restriction the better... |

we had that same problem, and solved by getting an offset air filter base |

Title: Re: Spacer selection Post by jrtracing on 03/22/11 at 9:47pm Brady Bell's old car that ended up as my backup car when I raced for Pedro, had a bad ass cold air box on it. The whole air cleaner was under the hood but it was enclosed with a vent out the back of the hood. |

Title: Re: Spacer selection Post by imracin68j on 03/22/11 at 9:50pm Blow Joey Silva's doors off with these CNC billet aluminum machined tapered ports cloned to super sucker. Light with vented routes to cool the fuel. Same CNC cut as Super Sucker. Between 10-30 typical bolt-on HP. I got a line on it. 79 bucks, no shipping, no tax. Hit me up.  The cool box is the way to go if you can do it |

Title: Re: Spacer selection Post by Chad_E._Jeffreys on 03/22/11 at 10:14pm All this high dollar spacer talk from the guy that thinks an increase at the back gate is the end of the world. Hey Billy, practice is priceless. Should we change this thread to how over priced spacers have become? LMFAO Chad |

Title: Re: Spacer selection Post by valleypro23 on 03/23/11 at 12:31pm jesus christ, i agree with imracin (think its billy), lil more tech talk and a lil less personal shots will go a long ways. regardless of dyno numbers i think a spacer ultimately boils down to throttle response. probably end up being totally driver preference. like anything with motors, just because it pops a huge number on the dyno doesnt mean that its going to outrun the guy with 50 less hp than you. |

Title: Re: Spacer selection Post by imracin68j on 03/23/11 at 1:11pm One thing about the WCSS is the front runners are getting everything out of those cars. You show up to one of those races you better have your A-game. It's not any one part that makes a car work better or win racers, it's a group of parts done correctly that makes a substancial difference. I remember asking my dad one time about something he was working on, weather or not it really made a difference. He told me in a stern voice, "Everything makes a difference." And there was no part on his car that was not perfect. That doesn't mean pretty or expensive, it just means perfect. When you have that attitude towards every bolt and part on your car you end up with something that does make a difference. If you half ass spots or have the attitude that it really doesn't matter you're going to be behind the guy who is making sure he's getting the most out of everything he has. There are exceptions at times but as a whole it plays true. So will a spacer win you a race? No. Is it part of the puzzle that can give you a better shot at it? Yes. One more thing. I know I'm biased but I consider my dad to be one of the smartest guys when it came to race prep. He was kind of a freak of nature as his engineering background convinced him everything was a equation and everything had a solution. Even folding rags or holding a wrench had to be done a specific way. As much as he knew, and he knew a lot, he never felt he was too smart to learn. He was buried in tech articles, race mags 1/3 of his day. Once you convince yourself you know it all, you're on the road to a rude awakening. |

Title: Re: Spacer selection Post by sj_valley_dave on 03/23/11 at 1:29pm I've been told that different heads and cams will like different spacers...I know that our engine was dynoed and it ended up making the best pwer and torque curve with a 2" open spacer. The engine builder Bill Hendrens said that most of the time a tapered spacer will work the best, but a SB2.2 head likes the open style better... |
