Respect for showing the results and changing your opinion on the results Brett!! Nobody is right all the time. I think most people will have gained more respect for you after watching this and how you handled it.
Bought two LT2 manifolds from Rock Auto at $175 each shipped. First just cleaned runners and used stock throttle body. Second one fully ported and snout opened past oring groove for 95mm throttle body. Been using second one for over two Years and love the results.
LT2 intake shines when you modify anything that is going to make the engine physically consume more air…heads/cam/etc… mine breathed awesome up top in the high rpm’s… good video,class👌🏻
After watching this, I'm glad I decided to get an LT2 with LT5 TB and saved the money. I've got CAI, LT2 intake kit w/ LT5 95mm TB, stage 2 cam kit (Cam Motion), ported the heads, 1 7/8" ARH headers, x-pipe, mid-pipes running into the stock NPP muffler. The car turned 502whp on the dyno and I'm completely satisfied. I'd love to be able to get the opportunity for you to put your hands on it for a tune because there's no doubt you could get more out of it, but I'm extremely happy with what I got at this point with my 2017 Camaro. I'll prolly go with an axle-back and I'll be done with it
My ss made 480 gpi tuned, e85, ported by me lt2, 95mm tb, 2" speed engineering headers. Then did 225btr cam and decked heads as much as possible with notched pistons. Made 541 again gpi tuned. Miss that car. 😪
Comment so much later here. When you compare these manifolds on a full bolt on Motor... you will (probably) see a much larger difference between them all. Would love to see this whole thing again on a Heads Cam Car with all the bolt-ons. Best guess is the MSD pulls way ahead. Just a guess. like I said.. would love to see that. No ones got time for that though.
hello awesome work. i have 2014 silverado 1500 5.3L Z71 LT. will it be good to port the L83. i also have L86 ported throttle body KAT-7250 on there now. let me know your suggestions plz thnx.
I was wondering if you could give me your opinion on my dyno numbers I was dynoed on a dynojet at 439hp and 463tq with dry rotofab your ported lt1 manifold 95 ported tb 1-7/8 catless headers and e85 I have a A8 does those numbers sound about right?
Been running an LT2 for a coupl3 months now, enjoy the slight increase in top end power, wasn't even going to buy one but my buddy sold me his already modified mani with the C8 cover for $250, so it was a no brainer, thinking of porting it and adding a 95 now.
Would be interested to see what an unported LT2 would make. Others have showed it was a negligible difference. Maybe 3hp or so. I've been watching for some times with the recent debate on the manifolds. I paid all of $170 for an LT2 delivered to my door. Appreciate what you have done. Modification to fit was maybe 45 min. Think I was all in $220 and maybe 30 min swap.
How would you say your porting compares to gpi porting where they remove the throttle body o ring ? Maybe a head to head video comparing the two that would be cool to see
Not to be argumentative (and for what it’s worth), but you can def run a 103 on an LT2. And you don’t need an extender for the map if you pull the factory wiring from the loom.
Well that’s what he said he didn’t want to cut up the loom on his daughter car. And also I believe you have to cut up the intake and then jb weld it for 103 to work?
@@FromVtotheD I guess I misunderstood what he was saying (kids and wife talking lol). I was just pointing out you don’t have to buy an extension harness or cut wires. You bore out/port the inlet into the o-ring channel. So you have to seal the TB, but no jb weld was needed on the one I ran.
I got a good deal on a ported LT2 manifold, think I’d go well with my setup? All I have is a rotofab intake and a ported stock throttle body. I don’t plan to go all out with my setup but for a good deal I’m willing to add a few ponies.

I just follow the data. And tell the truth about what I find. That is all we can do. The numbers fell where they fell. I appreciate the kind words.

How much hp did you gain ? Without a tune and with a tune ?
How much power did you gain on the one you ported?

I got a Camaro 2020 , lt2 not ported , do You recommend a 95 tb thats
ported , or non ported ? For that combo ?
The shirt joke had me laughing. Good video pray!
Do a ported BTR trinity
Both are right in my opinion, he tested against all stock for stock, you tested, ported for ported!! So a win for both I think💪🏾
I'm famous
Your stock ported LT1 manifold looks great and would probably be better on a 10 speed auto with no other mods.Great video, thx!
Yeah ditto! Thanks for not being so "confident" that you can't learn anything new!
this made me feel alil better about my setup lmao
Please explain why you aren’t a fan of the MSD
Excellent review guys, great hip pocket information for my future build...
I just picked up 18hp 27flb swapping to the 103 over stock on a ported msd 13.1 416
I really wanna see how all the intakes do with a tune as well ! Gives a lot of us more of an idea what we can get out of it
Great video man, absolutely love it!
What about the Holly LT intake? It’s cheaper then MSD and looks 100x better

Should have tested a Goertz intake manifold also.
6:30 for results

Very interested in seeing the btr mani, see how it compares to this testing

Did you have to tune after install
@@str8klownn713 I did not. No check engine lights or anything of the sort. Ran beautifully
Really wish you guys would have tuned each one
How would you say your porting compares to gpi porting where they remove the throttle body o ring ? Maybe a head to head video comparing the two that would be cool to see
I guess porting quality matters a lot
Ive been wanting a high ram, im fbo with lt2 intake. Would the high ram hurt me without a cam?
Nope just be sure to get the TCM tuned if you dont already.
A cam would wake that mf up fr
@SuperStockStowe oh i know its on the to do list for sure
A high ram will absolutely hurt power with the stock cam. That manifold is made for spinning to 7500+ rpm
Could you tune my 1995 LT1?
Appreciate you guys doing all the hard work & gathering information for us 👍

Great video!!!
Did i miss the hi ram results ?
We showed them on the dyno graph but we didn't have a free hi ram to slap on that day and it was really to see if the LT2 intake was worth a crap
Add the rapid_3d intake manifold to this!
Ported stock for bolt on cars ported lt2 for cammed cars
I got a good deal on a ported LT2 manifold, think I’d go well with my setup? All I have is a rotofab intake and a ported stock throttle body. I don’t plan to go all out with my setup but for a good deal I’m willing to add a few ponies.
is it stock tune?
It was tuned for the cold air intake it had but that was it. Tune wasn't changed between manifolds
@@prayperformance5137 so it’s pretty close to the stock tune? I heard the tune for the manifold is really minor
I just paid $760 for a ported LT2 shaved and ready to bolt on
Ouch.. Mine was $180.. and the porting took me about an hour with a dremel.. and drill..
