Humm, I would suggest going on HP Tuners forums and asking the question there. If someone has any information to make this work it would be some on there.

Planning on running the same throttle body but with a MSD manifold

[@EssMotorsports]

Good low cost option instead of like a 103 nick Williams or Katech. Just get the 95mm to 103mm adaptor so it's a smooth transition.

[@TheWolfMatt]

This may be a better option for me than to get the current 87mm TB on my 19 Sierra 6.2L (L86) the replacement ported TB from Katech. I went that route on my previous 17 Silverado 6.2L and had a noticeable difference between the two but at the end of the day, it was still an 87mm TB. I'm intrigued about the LT5 (ZR1) TB and how it may perform on my truck over the stock L86 TB. Given that the LT1 and L86 share the same parts, minus some differences in that it's a truck motor vs sports car, it should be the same installation. Nice video, I may go this route over my previous thought. I like running Corvette parts whenever possible, they always seem to work better that way.

[@EssMotorsports]

I would do the 95mm over ported 87mm because when they port 87mm they take out the ramp which causes lot of airflow right off idle. Which can cause Torque management issues. 95mm probably is cheaper as well

[@TheWolfMatt]

@@EssMotorsports I was in the mood for ordering parts for my truck anyways. Thanks for helping me seal the deal on this setup. Great vid btw. You get any gains out of the LT5 TB setup?

[@EssMotorsports]

@TheWolfMatt no HP gains as the intake necks down to 87mm and engine can't take advantage of the airflow. It's more throttle response/driving feel.

[@TheWolfMatt]

@@EssMotorsports Quick question. Did you have to install a new boot/sleeve for the increased diameter of the TB on the LT5 vs LT1? I'm thinking my factory bs is probably too small to fit the LT5 TB.

[@EssMotorsports]

@TheWolfMatt I had the rotofab sleeve which was pretty flexible so it fit good. I didn't try with the factory tube.

[@shaunmccuin5954]

Good video. Food for thought for when mine is out of warranty. Like the LT2 concept. Don’t know if it would fit under the strut tower brace? It would be cool to some how modify the stock covers to fit on top so it looked un-modified. Look forward to seeing your drive/tuning

[@EssMotorsports]

I believe on the 6th Gen forums people have installed the LT2 intake with a strut brace. But you have to trim the ribs off the intake top or notch the strut brace.

[@EssMotorsports]

This sounds easier!

[@mattraymond2935]

I was wondering the same any progress stock covers on an lt2?

[@EssMotorsports]

If I remember right I tired quickly to put covers on and was like not going to work. But I didn't try to hard. I like it better without. Someone on Camaro6 forums would probably know.

[@Blakehenry11]

I'm not completely sold on this mod bit I do appreciate the video. I hear your argument on the flow comparison but to spend that money on a spacer and throttlebody only to neck it back down just doesn't seem like that would be much of any gain. I think I'm gonna stick with the stock one and use that money somewhere else.

[@EssMotorsports]

If your looking for hp then headers be your first bet. Intake Manifold second. This is a supporting mod.

[@shaadydog1]

Sure if does, 90mm effective opening is like 86mm or something, 95mm is about 91mm so you neck down but the 90mm opening is seeing a full 90mm of flow

[@matt6951]

I’d love to see a dyno comparison.

[@EssMotorsports]

Richard Holdner had a really good live talk about throttle body size. Good listen. Basically, the 95mm is not going to add any power but will improve throttle response.

[@matt6951]

@@EssMotorsports so I’m a drag race, it’s worthless? Good to know. At $200 bucks, I might just get one anyways.

[@EssMotorsports]

Maybe not worthless, just not a power adder. I would buy mine again. Just saying if you have to buy other parts as well, I would get intake manifold, headers, air intake first.

@@matt6951 LT2 u could get away with the stock throttle body. If you go MSD the 95mm would be a good lower cost option compared to the nick Williams or katech TBs. Buy 95mm from rockauto if u do it was only like 160 when I bought mine.

[@YanA19887]

I just bought ported intake manifold to 95mm and soler 95mm TB which will fit directly to the intake opening. I have a C8. Since there’s no tuning yet will this set up be okay to run without any problems you think?

[@EssMotorsports]

So I am going to assume the c8 is similar torque based system. So it will be OK driving, it will have lower timing due to the more airflow at idle. My opinion is it's not going to hurt anything.

[@imanolgarcia716]

You think it’s possible to the port the adapter to match the 95 throttle body and port the neck of the Lt2 manifold to match the new size of the adapter . So instead of it going from 95 back to a 87 due to the manifold . Port as much possible from the Lt2 manifold and try to match it with the adapter(ported)

[@EssMotorsports]

Companies to do this like GPI but u can't port enough to have a true 95mm in the manifold neck. It gets too thin.

[@imanolgarcia716]

@@EssMotorsports thank you I’ll see how much I can port the snout to match the tb

[@jconn124]

Thank you for a very helpful video. One question. It seems like the adapter is the bottleneck, so is it possible to install without the adapter by drilling into the TB? Otherwise, how did “porting” the adapter go?

[@EssMotorsports]

U can drill and install directly but the lt1 or lt2 intake throat need to be ported to clear the throttle blade. Opening up the adapter was really easy with a sandpaper flap wheel. I only opened it up from 87mm to 89mm. On the lt1 or lt2 the throttle opening will be a restriction at some point if u have heads and cam probably. I am giving up maybe a couple hp but for a fraction of the price it's still a really good option. Car pulls strong at high rpm! 🔥

[@jconn124]

@@EssMotorsports thank you. I just ordered the LT2 manifold and LT5 throttle body. Planning on drilling the throttle body to bolt it right onto the manifold without using the adapter. Will be porting the runners and throttle opening on the manifold. No plans to do cam/heads in the near future- just long tube headers, e85, and tune (already have CAI). I like the LT2 better than the MSD because of: 1. Price 2. Low end hp/tq is better. What do you think of all that?

Hello bro, How many HP Increases by changing the TB to 95mm??? . Thanks nice Modification

[@EssMotorsports]

Idk about HP but I can definitely see from my logs I have way more airflow off idle. So it is more of a linear airflow curve then the stock TB. The throttle body is also I think is what changes your tune the most with the different airflow at lower rpm. Wideband would be recommended 👌

[@Hoesay2ss]

I recently installed lt2 intake throttle will not respond when floored on park or neutral when driving its no issue but on park throttle stays stuf for a second on 5k rpms. Anyone had same issue?

[@EssMotorsports]

If it's the stock throttle body. The lt2 intake should not cause any issues with the throttle not responding.

[@Mason1le]

How does this affect throttle response? I understand the concept of airflow and engine combustion but I am assuming youll get better pedal/throttle feel with this larger TB? Also can you do the LT2 intake manifold without a tune?

[@EssMotorsports]

Throttle response is hard to say yet as it's not completely tuned yet and I have timing taken out which affects throttle response a lot.

[@EssMotorsports]

About the LT2 intake its not a for sure yes or no cause every setup is different and I didn't run just the LT2 intake. But I'm trying to lean the car out actually cause it's actually too rich! Idk if that's because the rotofab or what. But the stock tune up top is not far off

[@emmanuelloaiza9257]

May I ask what sleeve you used to connect to CAI. The new 95mm throttle body is to big for the CAI. I have the Chevy performance CAI. Thanks

I did not change any of those settings. From other tunes I have seen on HP Tuner forum they changed the proportional delay. Not sure if that is needed or not.

Hey brother, from novice to novice.... I got a question. I installed the 95mm granatelli TB on a 2018 ram 5.7 Revved great in Park, but when I got her on the road and got on it, I had like a total system failure. All kinda dummy lights including the electric brake system. The code was a TAC failure. I recently got the unlocked PCM for tuning with the flashpaq F5 Any input on how to get this thing tuned properly would be awesome. I'm pretty new to the new vehicles and engine hop ups.

U can put it on. Let it idle 3 min shut off, start and idle 3 min again. As long as it doesn't throw a code it will be fine for couple days. The car will limit torque because of the extra airflow at low rpms. Wait for wot until it's tuned tho to be safe. 👍
