im building a 396 with AFR 210cc heades and i was trying to find out what would be a batter intake and do u thik the stealth ram fits under a corvette hood thanks alot :nopity

 

There is a place that makes a StealthRam that DOES fit under the Corvette hood. I don't have their web site handy but IM Grumpyvette for it.
Only thing about the StealthRam is it does not have provisions for an EGR, so passing emissions may be a problem.
I'm swapping out my motor for a 383 this winter and decided to try the StealthRam, it flows like mad.
Both are great intakes.

thanks alot i live in the state of MI and we dont have an eimsion test but which intake makes more power thanks :reddevil

 

Here's the link to the StealthRam that fits under the stock C4 hood.

the intake ports on the STEALTHRAM as it comes from HOLLEY fit the felpro #1205 gasket port size, thats a perfect match to the AFR 190cc heads.
this is a 1206 gasket and while its easily possiable to port it to fit , it does not leave any room for mistakes



I know of 3 people now useing the stealth ram on larger port heads, all needed to have a machine shop weld alittle extra metal to the upper port area and do minor machine work to allow the ports to be ported out to those larger ports sizes, but all three guys reported excellent results and power
personally I advise you just go with the AFR 190cc heads and avoid the problem as they flow enought to make over 500hp if the rest of the engine like the compression and cam is designed to use the stealth rams high air flow rate, but you can make it work with the larger heads ports with the help of a good machine shop. BTW those 1206 port size fits many of the larger 210cc-220cc heads available.

thanks alot good info the thing is i already have the heads and by any chance would u know if the stealth ram makes more power than the mini ram

thanks :blueangel:

 

Try using the search function for more info, there's been a ton of threads on the subject.

As for what I remember reading it isn't so much as a question of does it make more power, but at what rpm does it make the power. The big arguement about the Miniram vs. the Superram is the mini gets most of its power in the upper rpm range so you loose alot of low end torque, and the Super has lots of low end but still lacks on the top end (although still WAY better than stock).

Now from everything I have read on the three here is my take. The Stealth ram is the best of both worlds being a happy medium but up until recently wouldn't fit under the hood. I know this doesn't really answer your question but like I said I think it is just a question of where in the rpm range you want your power.

Me personally I would probably go with the Stealth Ram, just simply because I love the feel of low end torque.

 

thanks :cheers:

 

Have a buddy that had both on a 406 and the E.T.'s were minimal. :reddevil

 

I used the Fel-Pro 1205's on AFR 210's (391 motor) and the gaskets shroud the port like a mm at most, just ever so slight. I port matched(crudely) the HSTR to match the 1205's.

someone said they liked the SOTP torque or something like that so he would chose the HSTR......
Probably means the superram. That one provides gobs of push-you-back-in the seat torque. It's been my experience so far that my HSTR's torque curve is much flatter (easier on driveline) and will not push you back in your seat all at once, but gradually more and more as you build RPM.


so what kind of heads do you have?

thanks for the info man and i was woundring since im getting the same sit up on my motor what kind of HP / TQ did u get out of it and what ETs thanks :thumbs: :grouphug: :hurray: :_dupe: :party:

 

another one of these poll's...

stealth ram vs super ram...super ram vs miniram...miniram vs stealth ram....

There is a much higher quality piece in the above thread. Also the design is much better in my view. Also if you get a MINI RAM and go to sell it you will loose very little money due to a high resale. I doubt many would be interested in a painted box. I think that makes it looks cheap.

Also the MiniRam will fit 1206 gaskets without any work.

I can only assume your knocking the http://www.fasterdeals.com/garageindex.html
custom stealth ram, because your working for my competition who took my first proto-type design, and took the measurements off my corvette,then took that first proto type design and modified it for cheap production, made it from folded aluminum sheet metal, and started selling it before ever testing it on an engine!
or your looking at pictures and making up you mind on looks with ZERO INDEPENDANT COMPARITIVE DATA
since I know for a fact you have never tested BOTH of those two intakes and since I was the guy that came up with the basic idea, and have tested that first design , as it was an early discarded proto-type, and I found several problems with it, I can,t beleive that you would with no data, try and push a product that was built with NO TESTING EVER DONE on a actual engine!
IF your convinced its a better product BUY IT! TEST IT at YOUR EXPENCE, AND LET US KNOW HOW IT WORKS! (I ALREADY KNOW!)

:withstupid:

[flamesuiton] I have seen this topic posted several times and enjoy the discussions of the other more knowledgeable members on the subject. However it seems everytime the HSR issue comes up we get a little bit of this:

and then we get some of this:
You may think I am a newb but I have been lurking here forever. I have seen many more of grumpyvettes posts and have enjoyed them.

I have a 406 in my garage awaiting an intake, and after seeing this pizzing
match go on for months I would rather buy a high rise hood than to buy a plenum from the afformentioned parties.
:rant:
[/flamesuit off]

Sorry if I offended anyone but enough is enough already.

 

Well I'm one that's interested in that "Painted Box" because it's a PROVEN intake design with tests and data to back it up. I also think it looks cool. :cool:

 

I'm one for grumpyvettes design also and plan on buying one here shortly.

 

I'm not a show n shine type of a guy, but for whatever its worth, when I had the Stealthram that I think Grumpy is associated with, I thought it looked great !!!! Pretty easy to install as well.

However, I think development needs to continue, many issues came up such as a the fuel line set-up, which was unacceptable by me, throttle linkage was a problem with mine as well.... had to run extended bolts out. Not crazy about the small distributor either, but thats probably not a real issue.

The problems above are fairly minor, but if they're not already, they need to be included within a "kit" for the Stealthram retrofit.

I think the Stealthram just might be a very good intake system, however to actually better understand where the intake fits in with the others, a few experienced racers with known consistent set-ups running racing Slicks, a good but streetable torque converter and street gears of 3.73 or less needs to make the move from the SR to the HSR and document the results. I wanted to do this... and still do, but had problems with the first HSR.

Comparing the HSR to long tube runners on a dyno is not really going to show us a lot.... all aftermarket intakes will show substantial HP gains against a long tube runner set-up....Same with comparing et's vs long tubes.... would like to see somebody like Ralph, Vic or Scorp make this move.... or me :)

Somebody want to lend or consign me a HSR kit that will seal on my block... I'll give it an honest to goodness test over 1-2 months of track & dyno results vs a SR. The HSR should work great on my set-up considering I have extra cubes, 3000 rpm converter, 3.45 gears and a cam capable of spinning up to around 6200 rpm, yet is capable of passing any states smog. If it works.... I'll buy it and brag about it.

cheers,
Beach Bum

 

[B]This is the original design that you copied. This was made several years ago and milled out of a block of aluminum. I know this works and I know why yours does not.

Personally I would not use yours or the other, but the other is better in my opinion. I know this for fact and if you ever figure out what is wrong with yours (or the other for that matter), if you even know, your design won't be able to be repaired.

I have no relationship with the other guy nor do I have any desire to start one. This is an open forum and I am entitled to state my opinion. I don't think as a vendor you are supposed to be here promoting a product that you represent unless you pay to be a supporting vendor.

I have seen your past posts and I have yet to see any of your claims substantiated. I did see a picture of your 85 and the major ignition issues that you said was your test vehicle. The majority of the forum is new to swapping manifolds and could be perceived as impressionable. When someone with a vested interest in hacking a product that is just a box and thinks his box is something special, there is a problem.
