I have a Lingenfelter on my LS2 C6, and after blowing the motor at an HPDE event last weekend, I picked-up a 2015 C7 Z51 7-speed.

Are there any worthwhile gains on intakes on the LT1?

Any recommendations as to what works and what doesn't?

I was going to wait for Z07, but then this happened. The C7 is a whole different animal than the C6.

 

LT4 is the Z06, LT1 is what the Stingray has. To answer your question, yes, the intakes are showing gains. AFE's is probably the most popular at this point due to price and availability.

 

Ah, got it - thanks.

Corrected my post.

 

I personally have the AFE intake, Weapon-X ported throttle body, and the Diablo InTune with their AFE-specific tune on my car. Glad you're liking yours so far!

 

A combo like the AFE + one of our tuners with the preloaded aFe CAI tune will wake your C7 up nicely

 

Exactly! Very pleased with that combo on my car..

 

I have the AFE installed but didn't see any increase on the dyno.

 

Check out Halltech, I ran his CAI on my C6 and was very happy.
I also see that LMR has some real nice HP/TQ gains on the new CAI they have. 15hp/24tq.

Lingenfelter gained 10 HP on their engine dyno on their LT1. Less than we have seen elsewhere, but that was with our 589 cfm filter; our new 690 cfm filter would have added a few more since this was a built motor.
Katech gained 13 HP
Halltech 14/9
Texas Speed 10 HP
Vengeance Racing 19 HP (cam and headers onboard for before and after pulls)
Stingray Chevrolet 14 HP
Nickey Chicago 14 HP
Weapon X (can't find the most recent dynos)
Chucks Tuning 13.6 and 14.3lbs-ft (done on the LMR dyno)
Liberty Chevrolet 13

We have around 12 different shops that have validate the intake, but all with our 589 cfm filter, which is fine for stock. All the above dynos were bolt on without tuning to my knowledge.

I am sure our 689 cfm filter will add 2 to 3 hp on the modified LT1.

Here is the dyno done by LMR:

 

On an otherwise stock vehicle, I don't think it's worth the cost.

I've been down the intake/exhaust road too many times to continue to invest in anything other than a supercharger, or a built motor/HCI which in that case the intake system would yield greater results because it then becomes a source of real restriction.

If you want more power, do it right. Build it or boost it.

Paying for the system, an install for 12 hp is so minimal that it's not worth bothering IMO. Paying for a dyno tune to get another 10hp.

Spend over 1k for 20+ hp. Yikes.

Or spend 5k to 6k for 200+hp.

 

 

I agree save your money

 

Performance Exhaust for the additional $1195 (NPP Option) for 5 more hp is a much better deal.

 

Spoke to my tuner today (who is one of the top Vette guys in NC) and he said intake, headers and a tune. The ported TB's aren't worth anything, especially at $550.

 

Lol, that's a good point.

However, for me it's not about 5hp, it's about being able to cruise quietly with the wife, or dive loudly by myself, and not having to reinstall mufflers twice a day to get what I want as far as sound output.

The functionality is worth the cost for me even if there was no horsepower increase.

 

exactly

 

I agree 100%, since the cost/horsepower is really never really considered by the Corvette buyer, but I was illustrating to those few that mod their car that $900 for 14 hp is not bad compared to headers and other major mods. All a matter of choice and preference.

We are actually relieved that other less expensive intakes have shown up since our carbon fiber is not only expensive, but harder than ever to keep in stock. Boeing is consuming most of the prepreg available.

We have sold 83 intakes since the introduction of the Stinger, split evenly between Stinger Hybrids and StingerCKN systems (41/42). We know they are expensive and if we sold them factory direct, we could sell them at a price very competitive with the plastic units (speaking of our Hybrid);

In the past all Halltech carbon fiber has been sold factory direct, still with very small margins, but this time we wanted the tuners to have access to our products.

We could finish the second mold for the plastic version if there was sufficient interest, and sell them for $399.99 all day long, but I doubt they would sell. At this point, we'll wait on our Z06 to finish the plastic airbox, so that one mold will work for the C7 and C7Z. We have the CAD drawing finished, but need a Z06 to complete the fitment. Looks like December will bring that car to our shop.
