i have built a new plenum and throttle body and i am thinking about marketing them. i am looking to see how many people are REALLY interested. i have been told that i cannot post prices here so, feel free to PM me if you have any questions on anything. i picked up nearly 2 tenths of a second in the 1/4 mile with no tuning. i expect a lot more once i get some tuning done. this has put me into the 14 second range though. my throttle body is 65mm but i will probably be able to make them about 62mm unless someone wants a bigger one. please let me know who's interested.

This thread is useless without pictures.

 

i'll get some pics later. i've got a video that i am going to get transfered to the computer. i'll run out and snap a pic now.

 

Every one wnats a bigger one, don't they?

Highly interested.

 

here's a pic. edit: new pic. a little larger than the first.

 

What performance increases? Any other necassary mods?

 

my car was acting up when i tried to run it on the dyno. i'm going to do my best to get it back on the dyno real soon though, i think i got its problem takin care of. i already saw about a 10 hp increase at the rear wheeels and it was only able to run up to about 4,000 rpms. i ran it up to 7,000 (by the factory tach) at the drag strip to get it into the 14s. and the higher rpms is where it makes even more horsepower. i don't think that 20 hp at the wheels is out of the question on my current motor. tq is definately up also, i don't really know how much though.

no other mods are necessary. you will be able to bolt a stock throttle body up to the intake manifold if you do not purchase the throttle body too.

 

odd looking. Is it taller then stock? Looks like it might be.

Appears its same middle section, or is it new too?


I'd like to see what it does on a closer to stock engine myself as you do have the most modded n/a engine here.

 

looks good!

definalty need more pics

any chance of getting performance #'s on a stock 2.8/3.1?

 

High Flow air filter included with TB/Manifold?

 

It's looks like its name
A Spyder Intake!

 

its is a little taller than stock but it fits under a stock hood.

mid section is 'stock' but i was able to/had to do a lot of port work to port match it to the new upper.

yes, i want to get some numbers with it on a closer to stock motor, also. i do not know of anyone around here who has one though.

i am running stock paper filters under my dual snorkel intake. i didn't have any plans for any air filters...there's already an aftermarket for them.

 

I have a *cough* stock motor

 

you plannin to bring your *cough* stock motor to FL anytime soon?? lol. if you are, let me know.

 

I may be, but it will be other car, or plane

Would love to see what it would do for mine though.

 

if i was closer id volunteer. it would take forever to mail me one of those.

 

hey bet that would look real nice on the 3.4 im building....ill be sending a pm to you shortly

 

Where at in FL are u? I live in the tampa area and i have a basically stock firebird with a 2.8.

 

We are in Tampa, also. I'll PM you.

 

ill buy one, when will they be availible?

 

got any more pictures yet?

 

no, i haven't taken any more pics.

if anyone is a member on FL-thirdgen.org and is going to the statewide meet this saturday, this V6 will be there!

 

I'll be at the statewide with my bird. I'll make sure I bring a camera. I've been at the track with this car and it's the meanest 3rd gen v6 I've ever been around. And that was before the intake. Nice work .

 

We forgot to mention... we plan to ceramic coat all of these manifolds before they are shipped out. Those of you whom we sent prices to, that number will include ceramic coating!

 

Here's a new picture. Obviously, it shows the stock intake on the top and our new intake on the bottom.

 

that looks like a pretty nice improvment, i seem to be brain dead tonight but what is the stock size of the tb?

 

looks damn good, and for the price you quoted me its a good deal too

 

This would work fine with the stock ECU? Or would fuel pressure need to be adjusted?

 

Stock TB is 52mm. That TB is 65mm but we plan to make the production ones 62mm. ...62mm unless someone is doing a big build up and wants somethings bigger, we should be able to work with him/her.

edit: So far we haven't had any big issues with the stock computer. The air/fuel ratio could use a little help but, that may have been an issue with this motor before. We should have a test car with a stock 2.8 lined up. We just need to get it worked into the schedule to get the manifold on it and get some numbers from it. As always, I doubt tuning will hurt anything, though.

 

i got a 3.1 firebird and im getting headers/cam/ hopefully your plenum and tb should i get new injectors? if so what size? should this put me in the 15's?

 

this by any stretch of the imagination is not gonna knock seconds off your time, with other mods it will help greatly, but on its own i doubt you will see a huge gain. i'm not saying its not worth it just don't expect to go from 17 to 15 with this one mod

 

Looks like some decent work. Why not build the whole thing???
Like build a one piece manifold and ditch the stock lowers???
Then you can just use round tube. make a 1/4in plate for the bottom and just port it.

Id also not limit your design to the stock hood or being able to use a STB. If people need to run a 3-4in cowl or a hood scoop. So be it. Id like to see a full intake with some nice round long runners.

 

We do not see the need for new injectors. You can go up a couple of pounds on them if you feel the need, just make sure you get the computer tuned for them. However, we are running stock injectors, never even been professionally cleaned or anything and don't see any issues with them1. We don't see any reason why you couldn't run 15s with your setup. I don't know exactly what cam specs you'll be running or anything but a 15 second car is definately do-able.

kretos is right, this manifold and TB alone aren't going to knock seconds off of a quarter mile time but, in conjunction with other mods, you should see a pretty significant gain. The manifold and TB alone should make SOME difference though.

The reason that we haven't done a complete manifold yet is the the stock mid and lower sections are feasable. Could they be better? Probably so. However, we felt that the plenum and upper section of the runners were the most restrictive parts. So, developement of them was our top priority.

Some future design might not fit under a stock hood but we were happy when this one did. It makes things a little easier for people who don't want to or don't have funds available to buy an aftermarket hood. We do have a few other ideas but this one is the only one that has been built thus far.

Holy crap...I take a sabbatical and come back to the board to find THIS!!!??? AWESOME! I'm glad you finally broke 14's dude, makes me want to keep the Camaro (almost). But, school comes first

 

Would be sort of neat if the intake just peaked through the hood.
Just the top flat parts and 1/5th of the cone air cleaner. Either a sealed closed off cone type or run an open element cone.
Would look badss all polished up just peaking out.

Anyone skilled enough to mod an engine can do some body work. But yea no need for $800 hoods for $300 parts.

 

Gumby, if you wanted to...you could run about a half inch thick spacer between the new plenum and the mid section and cut those holes in your hood. I think that hlaf inch would probably put it just about where you want it!

 

would it be possible to give it a tad cleaner look at the neck area?
or would that be much harder to do?
id want it to look as if it came from the factory with a top half
like this
it already improves the looks of the engine as it looks like a v8 tpi system
and not the dumb X top lol

would you be able make it as a full unit top and bottom and round the side runners? or even have them bolt on like the v8 tpi system?
welds dont always look so nice
or would that make it harder to do ?


i would prefer a new plenum that fits under the stock hood
i got an iroc hood for a reason lol wouldnt want to have get a new hood just to mod the intake lol

dose the new throttle body support all the sensors?

and really why wont they let you put prices ?
even an estimate would be great
i am very interested keep me updated

 

The necks on the production pieces will probably be aluminum and welded right on the plenum. The prototype one has a steel neck, that is why it is bolted on like it is.

Later on, we might work up another setup that has more than just the plenum section. For now, all we have developed is the upper. There does seem to be a lot of interest in more than just the upper, though. One of our original thoughts was to have the runners bolted on the side on the plenum, however we decided that would not be cost effective and decided against the idea. The runners would still have to be welded to a flange and then the flange would bolt to the plenum, though.

The throttle body does use the stock sensors. Actually, we have set it up to use the stock "top plate" that is that housing for the IAC valve and vacuum tube hookups.

I don't really know why we were not allowed to post prices. But, they asked that we not do that, so we went along with the rules. However, this information is freely accessible through PMs. On that note, check your private messages...

Is your phone number

555-0400
555-0350
555-0300
555-0250
555-0200

 

?? I'm confused...
none of those numbers are for here...

 

haha i think thats code for something....but i could be crazy

 

I wondered about that! If its code directed at us, we need it decoded!

 

haha well heres what i thought...if you would like to order the intake its 555-0300....if you would like the TB its 555-0200 make sense? call now operators are standing by ha

 

I get it now.

 

I just threw a quick website together for the manifolds. .Hereit is.

i so cant wait for these to be available.....should add a nice gain to my 3.4 if i ever get it in. random thought, wonder how that intake will flow nitrous

 

You planning to run a nitrous dry setup? If not, you will probably plumb it in with the injectors, won't you? If you do spray it before the TB/plenum, the nitrous should flow just as well as the air does. It should be atomized when it comes out of the nozzle. So, it should mix right in with the air and flow right with it. However, I am no nitrous expert so, don't quote me on this one.

 

eh i dunno what kinda power adder im gonna use yet but just thought i woudl throw the question out there as im sure somebody was wondering. i just remember hearing that the stock intake didnt flow the wet system worth crap(if i remember correctly)

i cant wait to have my engine together now with all the options that are available as of late...any idea when your gonna do a GP

 

We're not real sure yet on a time frame for the group purchase. Hopefully we can get that all setup pretty soon.

If you all haven't checked out the website that was posted a few posts up, it has "figures" on it. There are no new pictures on there, yet. We will try to get a couple of new ones up pretty soon.

 

"figures" is that code for the phone numbers to call lol

thats cool just was wondering on the gp....if all goes well, which hopefully it will, ill be working two jobs within a couple weeks and making some serious progress on my engine(still powdercoating lol) so trying to make a schedule out for myself as to when to buy parts =)
