Can somebody please provide me a link or instructions on how to do this mod as I cannot search. I am thinking of getting my upper intake manifold honed tqice over.

Thanks alot,

Mark

Searching would do no good. Hence the word "secret." He'll tell us when he's ready.

no one knows what it is. its the one thing he has that none of us have. if i was him i wouldnt ever tell anyone.

i would not say that no one else knows but no one is going to spill the beans. even after its marketed and sold, it is still going to be a mystery.

and it should stay that way. people need to do their own research and work sometimes instead of just copying what other people have done. im not saying that we shouldnt share info but come on. stop being so lazy. if you dont have enough knowledge yourself, then dont mod. or just get an intake and be happy.

I do share just about everything else, but this one isn't for the majority of the DIYers. Everyone asked for it, everyone wants it so I will provide it. But only as complete with a core trade in.

There's not much info on it. I think the first real reference to it was in this thread.

If you have a problem with that then don't buy it.

I see no reason why I should give away everything for free. Do you?

MaximaPolak

iTrader: (9)

That's not what i ment though.....of course you can't give it away for free but somehow i think the price will be rediculously high.....

Why shouldn't he be allowed to make money? We do live in America (remember capitalism?) Their is nothing wrong with someone providing a product that people want and making a profit on it. This is how people make a living. This attitude is part of the reason we have relatively little aftermarket support.

SR, what price were you considering? what sort of guaranteed performance are you claiming? i mean i understand your not wanting to say anything, as the board is full of vultures, but you also can't say "gimme xxx and i'll give you back something that looks the same "

also, time frame completion. we can continue this via email. mgalvis01@hotmail.com

I'm interested as well in all the details. justcrossedintime@hotmail.com

Sorry, I thought this was the Soviet Union....how silly of me...

Is this just the removing the power valve mod?

That's the former Soviet Union.

BTW I've been trying to search for the answer for you on you idle problem with no luck. I do remember reading a thread where an org member had a similiar problem. Turned out he damage his TB by forcing the to far open while cleaning it. If I find the thread I'll let you know.

I sure the main reason he is not telling is he is still not sure if it is a sure thing or not and if it is safe. i have talked to him and he seem like a very nice guy. im sure he would like to make some money but it is not all about that.

Dude...don't be making ASSumptions. I am sure it will be "reasonably" priced, otherwise he would not be able to sell a whole lot of them. The price will be whatever the market bears. If it's "overpriced" he will either correct for it, or feel it's not worth his time to make at a lower price and thusly won't be available at all.

Does $300ish for a solid 10-15 REAL hp sound resonable? If you say no then I won't make it at all, because I don't know of anything you can buy for that price that will give you that much real power.

And that is just over the peak. It makes even more power at redline over the normal curve.
I plan on doing a stage one and a stage 2. Stage 1 for most people and stage 2 for those that want to make use of a 7200 RPM redline from a TS ecu.

Come on man. That would be pretty hardcore of me. If it were that simple I would have told everyone.

then figure it out yourself like he did

Just checking... I'm always looking for something funny to cackle about

Does this intake mod raise torque all across the board, BTW? (i.e. similar to the Y-pipe, I think...)

Thanx....I DID Open it Quite wide....I might have damaged it....

Would you be able to do the mod to a VI/2k VI?

And would these gains be all high RPM like most mods? It would be nice if we could get gains all across the power band. As I have an auto, high RPM power is not ALL that beneficial.

More power to him if he has customers more willing to use their checkbook to add power than do it themselves. That's how aftermarket performance gets started.

Increasing airflow through porting ( like I am almost certain SR20DEN is doing ) always adds more power as RPM's increase. If you want more power down low, add more displacement. If you port too much and increase runner size extensively, it can cost you some low speed airflow velocity, and actually hurt low end power.

Even though I've seen some org members poke fun at "rustang" owners, I used to be one, and I learned a lot about adding airflow to a motor that has great potential from the factory, but is hamstrung by stock parts.

I wouldn't say the VQ35 is hamstrung, but based on Studman's pics, there appears to be some room for improvement simply by cleaning up the runners in the lower intake, and anyplace else the air has to turn before it goes into the heads. There may be more gains available depending on design compromises, but I really don't think Nissan engineers leave much on the table.

I'm also not saying I know the "secret sauce" but I have some ideas.

Those little bumps that Studman was showing in his pics will hardly have any effect on anything. Removing them, opening up those runners if possible, and simply cleaning up the casting finish should help airlflow a bit.

FYI in the "rustang" community, a cartridge roll blend and polish to around 150grit on a Ford Racing performance lower intake usually adds around 10hp and takes only a few hours work. That's with a larger displacement motor with more ports than the VQ35 so it makes more difference, but you can see the potential. There's a lot more than 10hp available with the Ford stuff if you know how to port them properly.

The VQ35 lower is a piece of airflow artwork in comparison, but could still be polished to improve flow. I've not looked at the rest of the intake system, but I'm guessing there are gains to be made in the long, curving elbow and the mating area between it and the upper intake. I'm not sure what the upper intake has to offer.

I guess I need to take mine apart and have a look for myself like someone else here suggested.

How much would a stock intake manifold cost...Upper and Lower....
