Dyno results! LOD intake, ported heads and T.B.

You could take it back to the dyno and increase the RPM’s and star in the ‘Man Scatters LS Motor All Over Tuner’s Shop’ thread. People love that sh!t! Enjoy your build.

Try not to take offense to it. They may be rather blunt with their opinions but I don't think they would be so involved in this thread if they weren't thoroughly intrigued with your build, especially your LOD. I think they are just frustrated that you aren't using it to it's full potential when they (and I suppose the rest of us) are dying to know what all it can do. That doesn't mean you have to be the guinea pig though, and I sure as hell don't blame you. I just read through Frank's spring thread and I'm fairly certain he and his buddies would happily blow up their motors in the name of science. They're whackjobs for sure, and I love it. You're exactly right though, if they want to see what the LOD is capable of, they should all chip in buy one to test it out. Then they can send it to me when they're done!

make that 1 HAPPY whack job!

I’m for sure a whack job lol

I'm happy by baby is home in the warm garage...

Glad to hear that you're happy with you X1 manifold Clark. The wrinkle black looks great on a summit white car. For everyone wondering what it's capable of above 7k perhaps we can help. This is our shop 5th gen, we're finishing up the install of the new engine just in time for TX2K down here in houston at peitz performance tuning. Once everything is broken in it'll safely turn 7500+

Why do people think an ls3 will scatter and 7001 rpm.... they’ll take 7500 like sweet eff all

[christianchevell]

So on subject the torque staying low I agree with Bo White is due to the runners.....a High ram intake has always been known more for bad low end better high end RPM numbers and hurt torque actually as its design is that way and why so many don't make LS3# intakes that can better the stock one...look at the Fast its a lot like stock.... Vararam just teased us for years and never patented theirs with the long Plenum bowed mid ram, and MSD Gave up on a airforce for the ls3.... Sure sheet metals out there for cheap online but made more for carbs and not so great, and you got other Hideous things like the Nelson or the Edelbrock dual TB intake all more for a street rod not a Camaro....

But I have seen on here and written about on the net that having different than the stock gears makes a difference in the calculations and output on the dyno graph for those having the 3.91 gears versus the 3.45s also..... But hey we know a dyno is a tuning tool and the Intake having gained so much HP is great for making power but yes Torque is what moves you..... SO to me it would be interesting to see a dyno of stock cammed engine with stock gears versus one with the LOD intake and mild tune changes for the pair, and well ME frankly I want to see a stroker with mated to one of these. And if they make different tops for its as they said on their facebook and if they do up a LS7 one that can match to some small bore ls7 heads for a ls3 also........ This is the most interesting friggin development of the last few years IMO..........


Lots of stuff to consider.... And yes most ls3 springs are tested to only 7000 rpm, but exceeding that not so wise unless your like built shaft mounted rocker top end to be safe and to avoid valve float. A ls7 multiplies its rocker ratio is not the same making a cam be .030+ more higher in lift and also has by design features that make its 7k redline more safe, and being safer is smarter but not everyone is going to spend a lot of coin making it be able to rev to the moon all day long, or want to go that high with shifts with declining power production/torque with what ever cam they have with its power band...and the desired driving conditions of track, short track, street/strip etc

SO everything matters..... How many starbucks dude had matters......lol if they flunked English and had to learn to tune a fish........LOL

Lots of people (myself included) started out on older generation small blocks. Those in stock form would blow their brains out at 7k. I think for some that way of thinking is carried over to the LS world.

Ask and you shall recive. This motor going in is a 5.3 sleeved to a 4.185 bore with a 4 inch stroke. Dart pro 1 heads ported by SPS in Washington state. X1 intake (of course) and 2 inch primaries to a 3 inch x pipe on spintech mufflers.

I don't know why everyone keeps talking about the Runner length on his new intake. His torque numbers were the same with the stock LS3 intake. I had never seen a torque # that low with that TSP Cam and the stock intake. That's what I was trying to come up with an answer for. I think everyone understands short runners = more HP less tq. and long runners = less HP and more to. That is why I put the MSD intake on mine instead of the LS7. The MSD has a 1" shorter and moved my power back about 4-500 rpm's

[Clarkstar]

I agree it was strange... tuner said it was the gears. Maybe it was something in the tune? Not sure... but it's irrelevant at this point....

[Clarkstar]

This is the graph from the cam tune...

This one's is from the headers and z28 cai...
