WOW

That's pretty crazy... do you think an authentic one would have held up?

Hmm, if it's just cracked couldn't you just throw a bunch of duct tape over it to reseal it? I know it won't be pretty but should do the trick I'd imagine.

The concern I've had with those "snorkel" type of intakes that go over the core support is that they get "pinched" too much so that they clear the hood. Did you find that to be the case?

The Mugen replica requires the hood to be modified just like an authentic Mugen. Could that have been the reason?

I've been meaning to ask this, and maybe I should ask in the Gernpipe thread, but how is it driving around w/ the x-over @ 3600? In my AP1 3600 in 6th is going to happen pretty close to 65MPH - essentially highway speed. Some of the highways near me even have 65MPH limits so of course everyone is doing 70-80 MPH. Constantly being in VTEC on the highway has got to play hell for MPG and I can't imagine what it's like as far as volume of sound.

You can set up your car so that VTEC will only be activated when you are over a certain engine load. So when you are just cruising you will not be using VTEC. Once you get on the throttle more and the ECU sees the increased engine load and RPM it will activate VTEC.

The Mugen intake (and replica) don't work with the stock hood unless you cut it. The passage over the radiator support is significantly larger than any snorkel that would be compatible with the OEM hood.

I put some thick metal tape that's made for duct repair over the damaged area, but my 20 mile commute to and from work ripped right through it, and the damage got much worse. I removed the tape, and added a couple layers of fiber glass, so it's MUCH stronger now. It's also quieter.

i've been thinking of getting rid of my pwjdm intake after i got my car tuned.

it was causing weird wave patterns on the dyno down in the low rpm range.

i also noticed the chamber after the filter on mine vibrating pretty bad on full load, and after about 5000 rpm, it started collapsing into itself. even tried it without a filter on, and the same thing happened.

you can see it on the dyno sheet what i'm talking about

Well, we just had a long discussion about the results, and he gave me the green light to share them here.

While the results were not quite what I was able to get with my latest prototype, they are very good, especially considering its price and simplicity. If I hadn't already spent so much time and effort developing the "FrankInTake", which would be expensive and difficult to install and maintain, I would be happy with the Puffo.

BTW, something to note in each of the plots below is the lack of dips and bumps in the curves from the Puffo. All of the plots were done using the same tune, which has VTEC engagement at 3600 RPMs.
Sorry to go a bit off topic but what did you think of the hardware/mounting bracket on the Puffo?

Is the crack due to the fact that you did not cut the hood?

Gernby, what are your thoughts about the Puffo v. the PasswordJDM?

Any actual #s for this replica intake?

I'm locked into the STR ruleset, so as awesome as your new intake is, it'll be illegal for me to run, so I'm trying to find the next best alternative. Kinda between the Puffo / PWJDM / some sort of replica of Mugen / PWJDM.
