Looking to run a Hiram on my SS, I just want to know what exactly I have to cut to fit it onto my car. I know i have to cut the wiper cowl but do i have to cut anything else?

All the videos I’ve seen on installing the high ram had them cutting the firewall under the windshield area.

Everytime I search it up on YouTube I have no luck in regards to watching full install videos usually they just put the hi ram on and don’t explain what they needed to do for clearance except cut the hood, but in my case I’d probably go with the vfn max clearance hood. I don’t know how to feel about cutting the fire wall of the car, I’ve never been able to see how much you need to cut exactly

This is the only video where you can see the firewall cut. Even if you get the hood, you still have to cut the firewall from what I can tell.

Here is what Grok says -

To estimate 1/4-mile times for your 2022 Camaro SS with 515 rwhp and 485 lb-ft of torque (and the three intake options), we’ll use some real-world data, basic physics, and assumptions about your setup. Your car’s 10-speed automatic (10L90), stock weight (~3,750 lbs with driver), and likely 93-octane tune give us a good baseline. Trap speed and ET depend heavily on traction, launch, and gearing, so I’ll assume a decent launch (e.g., 1.8-1.9-second 60-ft time) with street tires or mild drag radials. Let’s break it down for each intake:

Baseline: LT2 Intake Manifold
Power: 515 rwhp / 485 lb-ft
ET Estimate: A stock 2022 Camaro SS (455 hp crank, ~400 rwhp) runs high 12s (12.7-12.9) at 110-112 mph. With your 515 rwhp, you’re in the low 11s. Using the horsepower-to-ET formula (ET ≈ 1350 / (rwhp/weight)^(1/3)), adjusted for real-world results:
Weight: 3,750 lbs
ET ≈ 11.3-11.5 seconds
Trap Speed: Trap speed correlates with horsepower more than torque. At 515 rwhp, expect 118-120 mph, consistent with tuned LT1 Camaros in this power range.
Final Estimate: 11.4 seconds at 119 mph
Assumes a solid launch and no major wheelspin. Drag radials could drop it to 11.2-11.3.

Ported MSD Atomic Intake
Power: 520-525 rwhp / 490-495 lb-ft
ET Estimate: The extra 5-10 rwhp and 5-10 lb-ft give a slight edge. The torque bump helps off the line, potentially shaving 0.05-0.1 seconds off the ET if traction holds. Recalculating:
ET ≈ 11.2-11.4 seconds
Trap Speed: With 525 rwhp, trap speed might creep up to 120-122 mph, reflecting the peak power gain.
Final Estimate: 11.3 seconds at 121 mph
The difference is small but measurable. A better 60-ft (e.g., 1.7-1.8) could push it to 11.1-11.2 with drag radials.

Holley Hi-Ram Intake
Power: 530-540 rwhp / 465-475 lb-ft
ET Estimate: The 15-25 rwhp gain boosts top-end, but the 10-20 lb-ft torque loss hurts the launch. On street tires, the ET might not drop much due to traction limits (still ~11.2-11.4). With drag radials or a prepped track, the higher RPM powerband could shine:
ET ≈ 11.1-11.3 seconds
Trap Speed: At 540 rwhp, trap speed jumps to 122-124 mph, reflecting the top-end focus of the Hi-Ram.
Final Estimate: 11.2 seconds at 123 mph
This assumes you can hook up the power. Without traction (e.g., stock tires), it might still run 11.3-11.4 but trap higher than the others.
Key Factors & Assumptions
Traction: The 10-speed’s quick shifts help, but 485+ lb-ft will spin street tires. Drag radials or a prepped track could drop ET by 0.1-0.2 seconds across the board.
Weight: No changes mentioned, so 3,750 lbs is assumed. Lightening the car (e.g., -100 lbs) could shave another 0.1 seconds.
Tune: Your current 515 rwhp implies a good tune. Each intake swap would need retuning to optimize shift points and AFR.
Launch: A 1.8-1.9 60-ft is realistic for a tuned auto Camaro SS on street tires. A torque converter upgrade could push this lower, helping all scenarios.

Summary Table
Intake RWHP Torque (lb-ft) 1/4-Mile ET Trap Speed
LT2 (Current) 515 485 11.4 sec 119 mph
Ported MSD Atomic 525 495 11.3 sec 121 mph
Holley Hi-Ram 540 475 11.2 sec 123 mph

Takeaway
LT2: Solid 11.4 at 119 mph—respectable for a street car.
MSD: Nips at 11.3 at 121 mph—best balance if traction holds.
Hi-Ram: Hits 11.2 at 123 mph—fastest potential, but torque loss might limit ET gains without sticky tires or track prep.
What’s your tire setup and track conditions like? That’ll refine these estimates further!


how about 60 mph to 130 mph


Estimating 60-130 mph times for your 2022 Camaro SS with the three intake options (LT2, ported MSD Atomic, and Holley Hi-Ram) is a fun challenge, as this metric focuses on rolling acceleration and top-end power—perfect for showcasing your mods. Unlike the 1/4-mile, this test minimizes launch variables (traction, 60-ft time) and highlights horsepower, gearing, and aerodynamics. Your 10-speed automatic (10L90) and current 515 rwhp / 485 lb-ft baseline give us a strong starting point. Let’s dive in.

Assumptions
Weight: 3,750 lbs with driver (stock Camaro SS curb weight ~3,600 lbs + 150 lbs driver).
Tires: Assuming street tires with decent grip; drag radials won’t matter much here since it’s a rolling start.
Gearing: The 10L90’s tight spread (4.70:1 first, 0.64:1 tenth) keeps you in the powerband, likely shifting between 4th and 6th gear during 60-130 mph.
Aerodynamics: Stock Camaro SS drag coefficient (~0.35 Cd) and frontal area apply.
Tune: Optimized for each intake, with peak power at 6,200-6,800 RPM depending on the setup.
Method: Using real-world data from tuned LT1 Camaros and adjusting with a power-to-weight formula (time ≈ k * (weight/hp)^0.5, calibrated with known benchmarks).

Baseline: LT2 Intake Manifold
Power: 515 rwhp / 485 lb-ft
Analysis: At 515 rwhp, you’re making ~13% more power than a stock Camaro SS (400 rwhp), which does 60-130 mph in ~10.5-11 seconds on average (per forums like Camaro6 and dyno-validated runs). Your torque keeps you strong out of 60 mph, and the horsepower carries you to 130 mph efficiently. The LT2’s long runners maintain a broad powerband, peaking around 6,200-6,500 RPM.
Estimate: Adjusted for your power-to-weight (7.28 lbs/rwhp):
60-130 mph: ~8.8-9.0 seconds
Benchmark: A 500 rwhp Camaro ZL1 (auto) does this in ~9.0-9.2 sec; your lighter weight and similar power suggest a slight edge.

Ported MSD Atomic Intake
Power: 520-525 rwhp / 490-495 lb-ft
Analysis: The 5-10 rwhp and 5-10 lb-ft bump over the LT2 improves acceleration slightly. The MSD’s optimized mid-range (better torque below 6,000 RPM) helps early in the pull, while the peak power (525 rwhp) sustains speed gains up top. Power-to-weight drops to ~7.14 lbs/rwhp, a small but measurable improvement.
Estimate: The extra grunt shaves a few tenths:
60-130 mph: ~8.6-8.8 seconds
The torque increase gives a slight edge exiting 60 mph, and the horsepower keeps it pulling harder past 100 mph.

Holley Hi-Ram Intake
Power: 530-540 rwhp / 465-475 lb-ft
Analysis: The Hi-Ram’s 15-25 rwhp gain shines here, as 60-130 mph is all about top-end power. The torque drop (465-475 lb-ft) matters less in a rolling start, where you’re already in the meat of the powerband (likely 4,500-7,000 RPM). Peak power shifts higher (6,800 RPM+), and at 540 rwhp, power-to-weight hits ~6.94 lbs/rwhp. This setup thrives above 100 mph, where aero drag dominates and raw horsepower rules.
Estimate: The top-end focus cuts time noticeably:
60-130 mph: ~8.4-8.6 seconds
Benchmark: A 550 rwhp C6 Corvette (similar weight, manual) does this in ~8.3-8.5 sec; your 10-speed’s efficiency keeps you close.
Summary Table
Intake RWHP Torque (lb-ft) 60-130 mph Time
LT2 (Current) 515 485 8.8-9.0 sec
Ported MSD Atomic 525 495 8.6-8.8 sec
Holley Hi-Ram 540 475 8.4-8.6 sec

Key Insights
LT2: 8.8-9.0 seconds is stout for a naturally aspirated street car—competitive with stock C7 Z06s (~9.0 sec).
MSD: 8.6-8.8 seconds edges into modified Mustang GT500 territory, thanks to the mid-range boost.
Hi-Ram: 8.4-8.6 seconds flirts with supercar territory (e.g., stock Hellcat is ~8.5 sec), leveraging that top-end punch.
Variables
Gearing/Shift Points: The 10-speed’s aggressive shifts keep you near peak power, amplifying these estimates. A custom tune optimizing shift RPM could trim 0.1-0.2 seconds.
Conditions: Headwinds or high temps could add 0.2-0.3 seconds; ideal weather (cool, dense air) might drop them slightly.
Driver: Rolling starts are less driver-dependent, but throttle modulation still matters.

WTF does any of this info have to do with cutting ?

[NYblack1le]

The only thing you’re cutting besides the hood is the “wiper cowl”. It is not an integral part of the firewall. It is easily removed and replaceable. The plastic cowl will need to be trimmed as well. I kept the rubber gasket. Some people cut that but it is not necessary and looks like crap.

Look at his other post where he recently asked about highram vs LT2 vs MSD.

Ok thank you, i figured it was not a super integral part but i wanted to be sure as i have not ever really been able to get a good view at what exactly needs to be cut because for some odd reason, there's very little info on this topic.

Peak power shifts higher (6,800 RPM+), and at 540 rwhp, power-to-weight hits ~6.94 lbs/rwhp. This setup thrives above 100 mph, where aero drag dominates and raw horsepower rules.
Estimate: The top-end focus cuts time noticeably:
60-130 mph: ~8.4-8.6 seconds
Benchmark: A 550 rwhp C6 Corvette (similar weight, manual) does this in ~8.3-8.5 sec; your 10-speed’s efficiency keeps you close.
Summary Table
Intake RWHP Torque (lb-ft) 60-130 mph Time
LT2 (Current) 515 485 8.8-9.0 sec
Ported MSD Atomic 525 495 8.6-8.8 sec
Holley Hi-Ram 540 475 8.4-8.6 sec

Key Insights
LT2: 8.8-9.0 seconds is stout for a naturally aspirated street car—competitive with stock C7 Z06s (~9.0 sec).
MSD: 8.6-8.8 seconds edges into modified Mustang GT500 territory, thanks to the mid-range boost.
Hi-Ram: 8.4-8.6 seconds flirts with supercar territory (e.g., stock Hellcat is ~8.5 sec), leveraging that top-end punch.
Variables
Gearing/Shift Points: The 10-speed’s aggressive shifts keep you near peak power, amplifying these estimates. A custom tune optimizing shift RPM could trim 0.1-0.2 seconds.
Conditions: Headwinds or high temps could add 0.2-0.3 seconds; ideal weather (cool, dense air) might drop them slightly.
Driver: Rolling starts are less driver-dependent, but throttle modulation still matters.

While this is probably all very accurate, it wouldn't really be able to take into account the fact that if i were to be going hi ram, i would be adding a few other smaller modifications to compliment the Hiram since i might as well go the full 9 and get a bigger TB/possibly go with an OTR if i can find a decent setup that doesn't require a lot of modifications lol

So we went from Boost, to Zl1, back to cutting up the car to fit a Hi-ram? How about the BTR Trinity Mid runner so you can maintain some resale value? Tomorrow is a different day, you might decide to go ZL1 again.

Lol after some thought and valuable input from you guys I’ve decided to just keep this car and build it how I want.i still do plan on boosting it though, my goal would be to go Hiram and then buy a procharger. However the BTR intake was on my radar as I’ve heard it’s good with boost. From what I’ve heard, correct me if I’m wrong, that the Hiram is still king?
