Youa actually believe that bs?

Doesn't that mean if we dyno'd with NO intake at all (but with the velocity stack (if this one even has one) ) we should all gain that much hp???? LOL.

When will you guys learn? Or at LEAST wait for a dyno from someone NOT with a vested finanical interest in the company?

What's the difference inbetween MAX and PEAK??

 

I have no idea... im not agreeing with the claims or anything.

Im just posting what Andy is writing. lol

 

As stated, Andy has a vested interest.... He hyped up the R2C intake as having those kind of gains, and the company came back and admitted their gains were in the 2-10 HP range (and trust me, they were in the 2-5 HP range).

I am not knocking the product. I have no doubt that the AFe (Takeda), Injen, Status Elite, Stillen, and R2C are all decent intakes. I just don't see any short ram style intake making more than 5-10 HP/TQ tops. I would like to see vendors call it like it is. It turns me off when they unnecessarily hype things up. Tell it like it is please....

I mean Cobb, who I trust as much as anyone else, said there was no point (and I know they have a dyno and real engineers). They clearly pointed out that the stock intake was not a restriction for anything up to forced induction. Here is some good reading for you intake junkies (and remember this is a company that also sells intakes):

Here is a GREAT exchange between Trey Cobb (Cobb guy) and John Concialdi (founder of AEM and all around auto guru). This is from the posts made after the blog linked above, but I think it pretty much tells you what you need to know about the stock air boxes....


Trey:

We should post the results with A/F ratio graphs but the issue isn’t the ECU making the car run richer or any ECU reset. We own the Consult-III (new factory scan tool) so we closely monitor all the factory sensors and learning (STFT/LTFT) during testing. The stock air boxes flow the amount of air demanded by the engine at stock levels. “Improving” the air boxes simply isn’t necessary unless you do something else to make the air pump (engine) demand more air.

We have concluded as Cobb has, that there is no better way to go than the stock intake system we have dyno tested a fleet of these cars with an amazing array of intakes (and those tested in the Cobb test) as well as others and in every instance, there was a power degradation. (Strangely this is not the case with the 350Z)We even changed the MAF output to see if there was any way to coax more power form the car and that was met with failure. Because we have some electronic skills here with respect to slewing the MAF output signal, we even tried larger diameter intakes with obvious more flow to no avail. Trey is right on the money in his previous post.

 

"Deeper pleats"... LOL

 

I have intakes, and if it wasn't for the sound/looks i would keep the stock airbox. I personally don't find that it helps that much. For the money anyways, esp since I have a full exhaust.

 

but overall, can we still safely say we can at LEAST expect to get around 5-10hp gain in a properly made set of intakes?

 

I'm with Jeff on this one. The only real change any of these intakes will make is in the sound and appearance. Any HP/TQ gains would hardly be noticeable in street use.
Moditus is a great money maker.

 

If you are stock maybe, When the injen CAI came out, Someone with HFCs only dynoed 3whp from them.

 

I had that once... my doctor perscribed a cream for it

 

I think anything over 5 HP from a short ram style intake is pushing it. The fact is, as pointed out by some of the more knowledgeable people in our industry, the stock intakes provide enough air flow. Intakes sound cool and look good, but I would not expect any power gains.

Think about it this way.... They may help on the VQ35DE. It has one filter, intake tube, and throttle body. The HR and VHR engines have 2 filters, 2 intake tubes, and 2 throttle bodies. Where the intake may have been a restriction on the DE motor, Nissan made sure it was not on the HR and VHR engines.

I would seriously recommend reading the Cobb blog I posted a link to above. They do a good job of covering the pros and cons in an unbiased manner.

 

Actually if you think about it, the heat soak issues that have plagued all other G35/350zs would be as great with this setup also. Motordyne has stated that at a stop, temps rise dramaticly. And during a take off, it's common to use 10-15 hp for the 1st 30 seconds or so. Not an acceptable trade off for me.

 

great blogs - thank you, thank you, thank you.

I am sick of all these intakes. We have enough.

Is that all these companies can make for our cars. How about a body kit or a new intake manifold or something. DAMN these intakes.

 

Someone on G37 posted their review and a video!!!
