Default Does a "High" flow air duct really increase hp....

I think the topic says it best. Does adding this product really help HP? Any dyno proof?

I installed one. It more or less completed my change out of everything in front of the throttle body. I can't say I saw any SOTP change. I think they will provide more benifit on cars with SC's.

:cheers:

I didnt think you used the elbow with a sc? I thought it mounted directly to the tb?

I am debating about lowering my radiator and custom fabricating a 3.5" to 4" pipe. IMO it will look alot cleaner and cost of mod less than $50.

According to the current issue of Vette Magazine, at least the Vararam does.

Your only asking about the air bridge or duct, right? You will never know. 5HP cannot be reliably measured.

For the money these air ducts go for and the few horsepower you gain from them, it isnt worth it. Spend your money on something else.

LAPD HF Air Duct & Coupler look great (but may rub you hood liner) and is "cheap" at $175. I am sure there are a few horses to be found somewhere in there-but it is more than likely not measurable.

To me, it would just compliment my "complete intake package" to match my complete "exhaust package."

Apparently the big tuners don't think so. Check a picture of their engine packages - they still use the stock setup.

Probably the bigger the motor the more it would help.

Hey Phil, keep me posted on the lowering of the radiator and using a peice of pipe. I have been looking into this for the last year and would like to figure out someway to get away from that kinked up bend across the top of the radiator like you are trying to do. Shoot me a e-mail and we can talk it over Nate

I have to agree. If there is a change it's not noticable. Most articles I read say it only adds HP if you run 100+.

For the mod you're considering I'd be leary of water ingestion.

I did the Blackwing and noticed some difference. When I added the powerduct and the high flow coupler it seemed like I noticed a difference.

On the other hand, it was very difficult to get on and I may have just been wishing the effort paid off???

Regardless, I purchased mine as a combo and it certainly looks much better than the poopiee that comes stock.

Sorry, you can't feel 5-10 HP, especially in a 350+ HP car. Maybe in a 85 HP Honda. :D

I noticed that on a picture I saw of a Lingenfelter modded engine about a year ago. I basically asked this same question here on the Forum and most of the responses said it's more of an appearance upgarde then a HP upgrade. I settled on just a Blackwing and passed on the air duct. If the air ducts sold for under $100 I may have picked one up but not at the prices they get for them.
