Will the HSP cold Air Intake increase Horsepower? *Duramax*

Install both kits and run them each on a dyno. Let's see of the open intake really hinders performance.

Loved WCFab 3 months ago, now all over HSP. Interesting 180 there...

[@T18skyguy]

I'm an aircraft mechanic, and on carbureted aircraft we have carb heat from the exhaust manifold by pulling a switch. We test this every time before take off. On run-up before takeoff we switch from cool air to hot air and the back to cool. At 1800 rpm when we switch to hot air the rpm drops to 1700. We look for this drop to know that it's working. That's a good bit of power you lose. The science behind it is cool air is more dense than hot air, and more dense air has more oxygen and that's the stuff we want.

[@Jedidyah7909]

[@turbosupra2jzdragracingtob249]

Actual intake temps will be based on intercooler efficiency mostly not actual ambient inlet temps

[@bassdaze]

i think most aftermarket cai look great, but ive always heard over the years the stock housing is just as good with slight mod to side fender and even home made rams provide killer numbers on trucks tested.. Mine is stock with slight mod, need to finish it off and get some numbers for comparison

[@Antonio1974K5Blazer]

I think I’ll go with the HSP kit but with a Banks cold air intake with the Ram air Super scoop. Banks intake is similar to stock as far as a completely enclosed box but with better air flow. And it’s made of plastic which stays cooler. Anyone can take 2 plates of metal and make an L shaped “Heat shield”.

[@keithkepple6524]

Fact: cooler air is more dense and will produce more HP.

[@allthingsradd]

It's been proven that the closed box systems provide better cold air density, the difference it seems as the build quality. HSP appears to have great quality builds 🤙

[@waynejohnson3388]

I'm new to the diesel world. I just bought a 2013 chevy silverado 2500HD 6.6L LML Duramax with 144,000 miles on it. I'm going to be following HSP as I'm beginning to learn about my LML. I just ordered the HSP hot side (drivers side) pipe for my 1st step and 1st mod to the truck. (The truck is 100% stock) I chose the hot side 1st mostly because it looks like the easiest 1st step. I also have a 100gph Air Dog lift pump waiting for warmer weather to install.

[@therealtrucker7564]

Just cut a hole in your stock box and take the passenger side headlight out if you want a huge improvement in your intake temps. Otherwise you’re just spending $400 for pretty parts. When it comes to the fab company’s HSP’s two piece ybridge is a lot easier to install over the wherli 1 piece, however, WC Fab has better customer service and shipping times. I had to wait 7 months for my HSP kit to come in the mail and was given the run around every time I contacted them. That being said I did order their intake, but that was knowing it was purely for aesthetic reasons.

[@therealtrucker7564]

HSP Diesel definitely not knocking the product or quality in any way. It would’ve been nice to know up front that I was going to have to wait for my parts and I would’ve been just fine. I spent a great deal of time researching between you guys, WC Fab, SDP, and pusher before putting my order in. One thing I would’ve liked is the option to add ybridge gaskets. I ordered a set online but they were the wrong size so I had to wait for the right ones to come in another week before installing.

[@therealtrucker7564]

HSP Diesel once again I prefer your product over WC Fab. My buddy went with wherli and when asked by guys which route should they go I recommend you guys first. I would like to also install a pusher ybridge and look at some of numbers that their setup is putting out.

[@35057]

I like the HSP Y Bridge better honestly. I like the split merge instead of just slamming some pipes together. I know it’s all under boost but it all helps airflow.

[@stevevanhook1413]

I have the HSP cold air intake looked great at first but the powder coat doesn't hold up also the tubing size is smaller than factor so the maf sensor needs to be calibrated for the smaller dia tubing.

[@mattward330]

I have an S&B with the Wcfab cold side intake pipe and on 100 degree day my intake air temp I can stay at about 2 degrees higher than the ambient temperature. Pretty good. Really wanting to get the banks boost tubes and switch to the banks ram air intake and see the difference in temps and performance.

[@chrisao1987]

At least the HSP has a heat shield. Not a fan of either. Honestly, i like the AFE washable filter that fits right into the stock box. That's what I did and it made a big difference for my truck. The WCFAB is not protected at all, it can get water sucked in from underneath, and it pulls hot air from the engine. However, I'm not a tune guy, I don't like tuners. I use my truck to tow, so it's not a show truck. For me why spend $300+ for a intake when I already have the piping I just need the filter. I purchased the AFE dry filter for $70 and my truck breaths a lot better, climbs hills with very little to no smoke, I get better fuel mileage, and it allows the turbo to spool quicker which I can hear out the exhaust. I achieved all those things for less than $80.

[@oldblue101rf]

It's because wc fab Is designed specifically for racing off road performance 👏 not normal everyday driving. 😀

More air in, more air out...internal combustion engines are nothing more than large air compressors...with the advent of computer controlled fuel systems, they will adjust the fuel mixture/ratio for added air intake...IF you're going to run an aftermarket cold air intake system, make sure to upgrade your exhaust system... 2002 GMC 2500HD LB7, 170k mi, Banks cold air intake Banks 4" SS complete exhaust(single)...

20 degrees difference at "Idle", is a terrible point to compare. The temperature difference will matter when you are moving not at idle. So, why compare temps at idle? Just curious, not looking to argue at all (fyi)

[@kalenpeters8658]

Exactly, when you're moving, all that fresh air running through your grille is pushing the hot air back, you're still getting a great amount of air through the fender like it was originally designed. Of course when you're stopped it'll be hotter, put your hand on that air box after a long trip, its hot too. And by the time it makes it into the combustion chamber, I cant see much of a difference being made. I love it how hsp's website says every 1 degree in intake air temp, loses 3 hp, so where im from, it was +40°c yesterday, and 6 months ago, it was -40°c, 80°c difference between seasons, and hsp is american, so thats a 144°f difference, x 3hp, 432hp loss between seasons? Lmao, thats negative hp on a stock truck 😂, even say a 3rd of that cuz your intake air temp wont be the same as ambient all the time, 100hp loss, it doesnt work that way lol. Id like to see someone take the same truck, dyno it, and monitor egt's on the same stretch of road, with the same trailer on etc, etc, with the wehrli kit, and the hsp kit, and then show me a difference, and not with the hsp guy or wehrli guy running the computer 😂

So wcfab doesn’t make a box for their intake. This may be an ignorant question, but would an HSP sealed box fit around a wcfab intake?

[@GFY..-..]

From what I believe is WCFabs piping is angled differently then HSP due to the fact that HSP has the box and WCFab doesn’t so they’re allowed to just run the filter at essentially a 45 degree angle then HSP doing a 90 degree into the box.

[@benbuttars5594]

@@GFY..-.. Bummer. I love the wcfab kit that I have, but If I could seal the air flow with a box and get a better end result, that would be good.

[@GFY..-..]

Ben Buttars honestly I wouldn’t be that worried about it. When you look at the pros who drag their trucks with no filters or piping and just mesh screens how much are you really gaining by sealing off the filter box that much? I almost think it would be a little more restrictive compared to an open filter hence why pros typically run right off the inlet of the turbo. I run the HSP but without the cover on top I mean if your towing for long distances maybe a seal box to keep the heat out but I think it’s a apples to apples comparison.

[@benbuttars5594]

@@GFY..-.. Good to know. Mine is essentially a daily driver and I wanted increase in power/lower egt's for towing. So that was my thought, overall long term, maybe lower ambient temperature would be better.
