G35 NA stroker with ITBs
has any herelooked into how much it cost to do something like this?
Mack is giving you the starting cost to design and tool up for a mass produced part, and then it may cost even more if your first design does not produce the results that you are looking for. and of course there is always the chance that no one will want to buy it. As for a one off air box for your specific application, the cost would depend on what you wanted it made of and how it had to be designed four your car. You willl have different factors such as what kind of forced induction, (ie...single /twin turbo,super charger) what you are using as engine management, (piggy back or stand alone ) just to name a few.
Nice way to twist my post BTW. Are you serious and are you talking about a custom one-off piece? If you're offering your services to custom fabricate a one-off piece, I'm sure I can get Intense to design and fabricate something in-house that both performs and looks awesome for significantly less $$$. 4 figures? Definitely. 5 figures??? LMAO
If your talking about developing a prototype that will be produced, Jenvey (or any other company) should bear much of the initial R&D investment for an FI capable airbox for the Jenvey ITB's that would be produced, marketed and sold for profit. Why should I or anyone else foot 100% of the cost to volunteer our car for a prototype?
I'd be a fool to spend 5 figures for an airbox alone when the stock plenum + spacer has made 1,000+whp on FI VQ's. Let's see... $138 spacer versus $10,000+ for ITB & airbox combo... Hmmm


Edit: Just noticed zxman69 posted while I was typing my response here. Again, it's absurd to expect a customer to finance 100% of a company's R&D for something that will be mass produced. If you're not willing to invest in your product, why should we?
Sorry Ivory.
It wasn't my intention to take Hal's thread about your car OT. I now regret that I even brought up the question of FI applications for these ITB's.Last edited by RudeG_v2.0; Dec 7, 2008 at 06:32 PM.

to be fair, you're overlooking a very simple thing - that the intake manifold is far more critical in terms of design for an NA car vs an FI car. When air is being forced in, you can get away with a much more limiting design. Velocity through the manifold no longer becomes as critical as it is when the engine is being asked to suck in the air it needs. Instead, the turbo (single or plural) becomes the most important component to making the desired power. A mediocre manifold like the stock unit can still make tons of power on an FI car. That's not to say there is not room for improvement, as there clearly is, but it becomes far less critical to making big #'s.
You did a great job of explaining it to me in your prior posts a few days ago. I took issue with what mack z posted in response to me after I posted a legitimate question, which you already addressed with a technical explanation, and after I acknowledged the complexities you explained.Bottom line: I'm not gonna pay all the expense (5 figures and then some) for a company to use me as a guinea pig for their R&D on something they intend to produce. What's the incentive to do that???

As Adam said Jenvey's priomary customer is not using these on a street car they design and build products for race teams all over the world. It took forever for Mack to convince them that anyone would be interested in using these on a street car, and then get them to build a airbox for them. Believe me when I tellyou that they have far more money in the develoment of that kit then $10,000 . It took over a year to bring them to market after I anounced they would be available and then over a year to get an air box setup that they are happy with. The Z and or vQ35 engine is only one of many kits that they have on the market and it is most definitely not one that has made back their initial investment. Mack is not trying to be rude but he basically tells it like it is, and to devolope a mass produced FI air box for this kit would be very costly. RUDE G if you where located here in South Florida I'm sure that he would be more that happy to build you a intake that would suite your needs.

It seemed like Mack was being a smart *** after Adam already addressed my prior post in which I asked why Jenvey didn't design an airbox to withstand FI applications. I now understand why this is being marketed more towards the hardcore NA guys. It's obvious that an ITB/airbox setup isn't necessary to make big power on FI VQ's anyway and that such a setup is very costly. Considering the cost of an airbox to withstand boost, it's definitely not a bang-for-the-buck mod for FI. A custom airbox/ITB setup on a boosted Z or G sounds like something for a guy who wants to be uberBALLER and have bragging rights.Again, sorry for taking this thread OT about FI applications. I thought I was asking a legitimate question at the time.

jenvey already has a customer base - no point in them reinventing the wheel really as they've been around for a long time now satisfying that base (primarily race teams) - those customers do not have forced induction due to class restrictions. For the guy who has an FI setup that seriously wants ITB's, it could be done and that person presumably would have the resources to legitimately make it happen.

Why not design the box to withstand boost? Then Jenvey would have both the NA and FI market for these ITB's covered with a single design.
