Check out the results from our dyno testing of GM's LT2 Intake Manifold on a 2019 Camaro SS! Comparisons shown against the Camaro's stock LT1 Manifold and Holley's MSD Atomic Manifold. gwatneyperform...
Most shops dunking base LT1 mani vs ported LT1 mani aren’t seeing any real power increases. A few got 2 hp. But 6-7 hp, must be the smoothing method used. I can verify that the LT2 mani is better on a LT1 vs MSD as well as costs.
Basically the Lt2 is great for shorter runs and the MSD in the higher rpm. So if ur shift points are 6400 6500 your killing it. Basically get what you paY for
I was curious as to what the LT2 mani would do on an LT1. I already bought an MSD and it’s on my car but I was wondering if the LT2 manifold would be any better. Thanks for sharing
So essentially the same results as with the FAST manifold, lots of money for minimal gains over stock LT2. Spending $1200 for essentially nothing more than eye candy may be important to those compensating..
Pray isn't onboard with the LT2. He says 20 plus peak more with stock MSD than full ported LT2. Not sure what/who to believe anymore. Both on a stock unported TB, maybe that's the problem? Makes me think the unported LT2 and ported 95mm are still a good way to go.
Didnt GM say that the only reason they were able to put this taller manifold on the c8 was because they did not need to worry about frontwards visibility? Yet it seems to fit neatly under the camaros hood... unless they were only referring to the c7.
There is also pedo crash test standard, that calls for some space between top of engine and the hood. C8 doesn't have to worry about that, and from the sounds of it, neither does Camaro.
A new intake option sounds great then. The LT2 shares a lot from the LT1 and seeing as how its doubtful the camaro will get a new engine this gen due to poor sales. Making an "LT1.5" may be a decent option by swapping on some LT2 parts
I've got a Camaro SS with ported throttle body and a roto-fab intake. It seems like for the cost, the LT2 manifold is a total no-brainer. I wonder if the ECU will still play nice being stock with ALL of the air intake components modified?
Thank You came back for a refresh to my Memory. I have heard the LT2 manifold can be modified to fit under the Corvette C7 Cowl. Since we are Normally asperated so far. low pressure, more like vacuum pressure. Can you suggest a source for a LT2 manifold with modification to fit the Corvette for N/A engine? I could cut the cowl but it may be too big a cut to be done aesthetically pleasing. 1/2 rise over the rear end of the intake is no that big a deal to me. 1 inch rise started to look really weird. Thanks Dennis in Virginia
Did the LT2 intake bolt straight on to the LT1? And we’re there any modifications you had to do to run this intake? Any clearancing or rerouting hoses or lines?
I’m interested in buying one of these when you guys offer the direct fit manifold in the future. Will this work on the stock tune or do I need a tune? Seems like I don’t need a tune?
It will require adding a fitting in to the back of the manifold for the brake booster - as soon as we get more inventory available, we will be offering a ready-to-go, bolt-on manifold.
Swapped out an l83 for an l86. No one told me about the difference in exhaust, intake manifold and throttle body so I currently have the 80mm that was on the l83. Thinking about getting the l86 intake or the lt2 but wanted to get some opinions from everyone. I did my exhaust already from Texas speed. Headers all the way back. Single 3.5 " help please lol
People have tried the LT1 intake on the L86. The L86 intake is designed for a truck power-curve. If you put on an LT1 intake, you will shift everything towards the upper RPM range rather than mid- and low-RPM. I guess it depends what you use your truck for.
So if I buy that lt2 on the link I gave for my c7 LT1 what do I need to do to put it on do I need all the map sensors If there something u can provide to make it fit
Yeah, something doesn't seem right there to me either. Your 93 octane number seems low to have that tuned. I ran the exact same combo on 93 octane and I was about 445rwhp with a Diablo tune.
@@Blakehenry11 did yours have the stock headers and exhaust? I’m putting 1 7/8 headers with x pipe at the end of June and I’ll see how much more I get. I have a 21 Camaro SS
Fudged numbers stock. Most stock LT1’s are in the 392-407 rwhp range. 450+ rwhpon just E85 is insane, impossible. I’ve NEVER seen E85 add over 40-50 rwhp to ANY vehicle. 12-25 rwhp yes, but 40+ rwhp, no way.
