Helix Throttle Body Spacer

[Motorsport-SVX]

Ive been selling and using the HELIX brand throttle body
spacers now for about 7 yrs and have never had 1 come back
with a customer not happy with using it,
Always better MPG and small hp gain, 4-7 hp
I put one on my Vehicross last yr and love it.
So now Im getting them made for the SVXs.

Outlaw engineering seems to be defunct. Can this company make intake manifold spacers as well? Several people on the Facebook groups have been asking about them. They seem to be popular for eg33 modders, so there is a market for them.

yeah, no problem...
do someone have a pair to loan us so we can
possibly use to spec them out ?
If not, I can probably send them a pair of gaskets
to mock up some prototypes.
How thick ?

I have 2 sources that can do this for us
One will probably use billet aluminum, but the other will
actually use Phenolic material to limit heat transfer as
much as possible, this material is a smarter way to go.
Not sure what your originals where made out of.

The spacer should look something like this for the throttle body
and be about 1" thick when done...

[Tireiron]

For the intake manifold, just use 1 gasket as a template, they are symmetrical. The old ones are phenolic, aluminum would defeat the purpose of the part. Most phenolic spacers I deal with are around 8mm thick.

Just a caution to throw in here. There is no way you'll be able to use a TB spacer as thick as the one in the photo unless you want to take a chunk out of the firewall for clearance.;)

i was gonna say, how big can you even go on an svx? the intake is a pain enough to put on with that clearance

[theflystyle]

Here is a picture of the Outlaw spacers... Times like these make me wish I had a 3D printer. I could make a negative and cast these bad boys.

My thoughts exactly!;)

[EdWindows]

I have a set of the Outlaw spacers on my engine, and I still have a problem getting the snorkel on and off with the 1/4" reduced clearance.

[Motorsport-SVX]

I think theres enough room
Once the prototype is done Im going to test fit it on one
of our cars and take it from there..Nothing would ever get
done if we had the cant do attitude all the time :)
We like a good challenge anyways

[SVXRide]

note that I didn't say you couldn't do it, only that you're going to have to take a chunk out of the firewall to make it fit. ;)

the alternatives are fabricating a new snorkus that is shallower or flipping the intake so the TB is up by the alternator...

good luck :):)

[Motorsport-SVX]

what is the thickness exactly in metric or std
we need the spacers made for the manifolds ?
and we only need one pattern right ? because they
are a mirror image of each other ? or am I wrong..

[Tireiron]

You are correct, they are symmetrical side to side. The important one is between the heads and the intake manifold. Around an 8mm phenolic spacer should sit about right. The one between the upper and lower manifold doesn't matter if you keep the heat separated from the heads to the lower manifold. The intake manifold gasket from Subaru is almost dead on, I've never felt the need to port match a Subaru intake because of how close everything lines up.

[Motorsport-SVX]

so then we just want the 2 pcs from man to man, correct, 8mm is ok
thx, I have a guy who can make me the 2 pcs manifold
to manifold units, but we have to buy a min of 70 the
way it looks, which would do 35 cars.
No pricing yet.
Are people sourcing out there own gaskets from their
local dealer and bolts from the hardware store ?

[Tireiron]

No, you want to make the head to lower intake manifold. Completely separate the intake manifold from the head to keep the heat out of it all. The gaskets are readily available from the dealer. Even 4mm would work fine with a phenolic material to keep the heat out of the intake manifold. If you have ever leaned your hand on the intake manifold after a long highway drive you will understand how hot it gets from the heads transferring heat to it.

The main benefit of this is not to increase the volume of the intake manifold, but to keep the heat from the engine block out of it. With the design of the iris valve (when working correctly) the intake manifold is setup very well to go from long runner to short runner as the RPMs increase and the tiny amount of extra volume from spacing the intake manifold up or spacing out the throttlebody will make no noticeable difference. If you want to make a real difference in how the engine breaths, do some head work, cams and valve work. The intake is designed very well from air box to head.

[Motorsport-SVX]

Either would work, Ive been using phenolic spacers on mustang 5.0
since 87...and the ones we used on those car, split the upper and
lower intake. Simple, easy and effective.
The lower one looks like more of a pain to install, but youd be stopping
the heat sooner. The upper ones would increase runner length a bit
would could also help.
Ill check both possibilities

[Motorsport-SVX]

post up a pic of which one you are referring to

[SVXRide]

Not to beat a dead horse here, but is anyone keeping track of the direction this thread is going? Just eyeballing the pic of the Helix spacer, I'm going to guess that it's at least one inch thick (25.4mm). You're now discussing basically a thick phenolic gasket (4mm). You will not see the results that have been seen with a 25.4mm thick spacer. :cool:

The (still available) Outlaw Engineering kits came with either preatached gaskets or plain without any gaskets but always came with bolts that fit.
I like using only Subaru factory gaskets.
I have no other source for intake manifold gaskets.

Does this mean your guy is done with my throttle body and wants to ship it back to me?;)

seriously?

Who is still selling them?

And just to move things along, in the picture below, the area around #11 is what is being suggested.

[Motorsport-SVX]

the area in question is exactly what I was thinking
these where made for, but in a few post it made it sound
as if there was another area (new to me haha) that someone
was wanting spacers made for.

Tom, it should be coming back to you soon buddy, do you miss it ?
haha.

If all goes well Ill have a prototype to try on my car in about a week
As for the Phenolic spacers , I should have an answer on those soon too.
I may have to start a thread on how many people may be in for
the intake spacers and how many pairs of those we can expect to maybe
move in the first few months.

As for the gaskets, I use OEM only, Ive tried other brands and they
are noticeably inferior to factory gaskets.

[Motorsport-SVX]

got the 1st TB spacer made..
going to try to test fit it this week and then see what sort of results we get from it. Im confident the improvement will be there, all my other cars
have these spacers already on them ( my vehicross etc...)
Once I get all the little details worked out, longer bolts, extra gaskets etc
I hope to have them on the market by the end of the month.

[Motorsport-SVX]

ah, here is a pic or two

[SVXRide]

Dayle,

Impressive! Nice machining work. My concern continues to be being able to bolt the spacer and TB and Snorkus all on without having to take a 10# sledge to the firewall.;)

It is one inch thick.
It should bolt on without a problem.
I have had it in my hands and the machining was very nice indeed.

How much of an improvement will you see with our multiport injection...? Spacers were more useful for carb/throttle body injection I believe. Without a pre and post Dyno chart, I would pump the cost of a spacer towards a stickier set of tires. Easy DIY and pretty to look at might be it's main advantages.

If the $200 invested on Dyno runs showed some HP/torque increase, I would see this product selling better.

[Motorsport-SVX]

the part itself will be about $150..
I dont need a dyno to tell me if my gas mileage is going up.
In a nutshell, Ive been selling this exact product now for about
6 yrs. Ive literally sold hundreds to various cars, 90% of them
EFI throttle body just like ours, all with excellent results.
Ive given every customer a money back guarantee if they dont
like it within 6 months , ..6 months to try it, and if they didnt like
it they could bring it back for all their $ back. Not 1 person in 6 yrs
has ever brought one back not satisfied with the results. They all
have noticed better gas mileage as well and more seat of the pants
feel in power. And most would admit they paid for themselves what
they saved in gas in the first yr.
Not to mention Ive had one on my own Isuzu now for over a yr and
love it.
I dont need dyno sheets and b/s to sell the product, it sells itself.
and I wouldnt go thru all the headache of R&D etc if I didnt believe
in it to be honest. Its not just about making money, its about selling
a product I know that works and I can sell with confidence. Thats
just how we do business.
Dyno charts dont give real world results and can be faked, but if you
want to go along believing everything a dyno tells you is good, thats fine.
Past customers testimonies with their real world results are what
I go on as more legit.

[Motorsport-SVX]

that said, Im pretty sure Taylor / Vertex who is the manufacturer
for us of the Helix spacer dyno sheets on their website for various
vehicles. You can probably go on youtube and find some too if
it makes you feel better on buying a product. Just make sure you
look at the Helix brand tests, as theirs design is patented and the
best out there.

[elemgee]

I saw this Helix throttle body spacer for sale on Planet SVX and am curious as to what kind of mileage (and to a lesser degree, horsepower) gains one could expect?
