Administrators BRAAP Posted August 25, 2007 Administrators Share Posted August 25, 2007 Prime EMS and Rusch Motorsports split the cost of a crane scale which arrived yesterday. 1000 lb capacity, .2 lbs resolution. The first engine we weighed is a complete L-24 with early SU carbs, exhaust manifold, etc. Results are posted in the defintive weight thread linked below. We have already secured other engines to weigh over the next couple weeks including a 2JZ, VG30DE, LS-6, VH45DE, L-28, VQ35DE, various SBC’s, possibly an SBF. We would like to also weigh an SR20, KA24, the various RB’s, the Yota V-8’s, big blocks, etc. Anyone close to the Portland Oregon metro area with an engine/trans to weigh, drop me or Ron Tyler a PM.

rudypoochris Posted August 27, 2007 Share Posted August 27, 2007 Are magazine weight quotes good, or are we sticking to real data? EDIT: Just noticed the first hand clause. Quote Link to comment Share on other sites More sharing options...
Administrators BRAAP Posted September 3, 2007 Author Administrators Share Posted September 3, 2007 Just updated the “definitive” engine trans weight thread with the following engine trans weights… Weighed “Savage42”’s Corvette LS6 with 4L60E, headers, alternator, engine and trans wet; Suby EJ-22 engine only; Nissan VG30DETT engine only; ’03 GM Vortec 5.3 W/Magna-charger and 4L60E.

Racin_Jason Posted September 3, 2007 Share Posted September 3, 2007 Thanks to all who are involved with this. What alot of time, money and hassle on your parts for everyones sake. Very nice of you's! I'm really looking forward to the results of this list. Certainly will be nice to have real world data for gearheads! Jason Quote Link to comment Share on other sites More sharing options...
Pop N Wood Posted September 3, 2007 Share Posted September 3, 2007 This is pretty cool. Not complaining or anything, nothing but kudos, but it would be nice to see the weight of the LS6 without trans. Quote Link to comment Share on other sites More sharing options...
Savage42 Posted September 4, 2007 Share Posted September 4, 2007 According to Sallee Chevrolet, here's some info on the 4L60E: The 4L60 transmission is the successor to the workhorse 700R4 four-speed automatic.... Weight (with converter): 164 lbs. (dry) 184 lbs. (wet) ... Using that info, if you subtract the trans weight from the overall weight, it puts the LSX (with both motors not having A/C) at 425 lbs (wet) and the L24 at 365ish (if you add oil & oil pump), so a 60 lbs difference. Not too bad for triple the HP!! Quote Link to comment Share on other sites More sharing options...
X64v Posted September 5, 2007 Share Posted September 5, 2007 Very awesome thread, ron and braaap! Definitive weights are exactly what we need to make informed choices, and stop the bickering. Thank you guys! Quote Link to comment Share on other sites More sharing options...
cygnusx1 Posted September 5, 2007 Share Posted September 5, 2007 I don't want to open up a contest but I just want to say that when I pulled the head off of my turbo motor, I was surprised at how light it was. I realized then that the center of gravity of the L28 motor is actually pretty low. Even though it is a tall motor most of the mass is down, near, or below the wheel hubs.

bjhines Posted September 5, 2007 Share Posted September 5, 2007 Thanks for going to this trouble. I realize you are weighing what you have on hand. But there are still a LOT of considerations that have to be made to make these numbers meaningful to everyone. For instance; Manual vs Automatic includes a lot of other pieces besides the trannys themselves. Most of us building up the older SBC engines are using a lot of lightweight components.The ancillary systems for carbed hot-rod engines are simple and lightweight. These may not compare easily to the more complex late model LSx engines. You would need to set them all up in running condition to get more useful weights.

Roostmonkey Posted September 5, 2007 Share Posted September 5, 2007 I have the RB26 w/ RB25 tranny and the SR20det and tranny are coming from Cali as I type. Should see them by mid next week.I will also weigh an L16 w/ 4 speed. I have all these engines that need new homes and a scale that will hang from the lift.

Administrators BRAAP Posted September 6, 2007 Author Administrators Share Posted September 6, 2007 Thank you guys for the support regarding the “definitive weights” thread. Firstly, the “Definitive weights” thread “is” a compromise. No argument about that. For the amount of our own money, effort, and time, we are willing to put forth into that endeavor purely for the sole purpose of sharing our findings with the HybridZ members, this is as detailed as we are currently willing to make it. We encourage all members who have access to accurate scales to contribute to that thread, all we ask is that you follow the guidelines as posted in the first post in that thread. If anyone is interested in building and maintaining a detailed spread sheet of sorts for that thread, we would be glad to have you on board. If someone is wiling to sponsor our time and supplies, then we would be glad to take this to a whole new level and establish SAE style standards for weighing engines and power train combinations. The reason behind the “definitive engine weights” thread? In our searches for engine and power train weights in the past, we have not been able to find a standard for which engines are weighed “to” and what engine/power train weights we did find contradicted others findings, so who were we to believe? In my not so humble opinion, all of those weights we found posted on the internet, including those found in other threads here on HybridZ are worthless. This new thread is an attempt to present a more accurate representation of what specific power trains do weigh with and without certain accessories and options. The definitive weights thread isn’t going to satisfy just one particular engine or project, i.e. SBC, LSx, V-8 Automatic powered Z cars, etc, nor are we going to go through the trouble of equipping each and every engine we weigh with exactly what it takes for it run because who is to say what “should” and “should not” be included during the weigh in, i.e. how much of the EFI harness, vacuum hoses to the canister, the canister itself, fuel pump, etc, for the varying power trains, "Carbed" vs "Fuel injected", "custom engine conversions" vs "as installed OE", hence the compromises we made for that thread. For the SBC alone, there are SOOO many different configurations when you take into account induction, exhaust, heads, ancillaries, etc, there is NO way we could possibly cover all bases. The list created here isn’t ideal nor will it encompass every possible engine trans configuration that could be stuffed under the hood of a Z car. What that thread will offer is a definitive guide more accurately portraying a specific power train combinations weight with a short list of what "is" and "is not" included. As for the 2 LSx/Auto power trains currenlty posted, purely coincidence that I had access to two LSx power trains last Thursday, both just happened to have 4L60E transmissions mated to them. We will be weighing more than a few traditional SBC combos including iron heads, aluminum heads, w/T-56, etc. (I am currently building a traditional SBC 350 with aluminum heads, aluminum water pump, T-56 etc). We will also be weighing other power plants as time goes on, including my VH45DE, Dave Lums VQ35DE, a 2JZ, a few SBF’s, etc. Again, thank you guys for your support and stay tuned for more weigh-ins… Quote Link to comment Share on other sites More sharing options...

rudypoochris Posted November 1, 2007 Share Posted November 1, 2007 Seems about right. Chevrolet listed the LS1 weight at 497lbs prepped for a manual transmission. According to tremec, the T-56 weighs between 108-129lbs. So that would be 605lbs to 626lbs. Not sure if the LS1 weight Chevrolet listed was dry or wet.
