View Full Version : Volant - The long awaited very custom install (pics)

06-20-07, 07:48 PM
Ok guys here it is. This is the customized install of the Volant air box in my DTS. I have now overcome all the things Volant forgot about.

This is my baffle. It's 1" think foam board insulation cut to fit the box intake


This is the baffle in the box

Next is my custom snorkel made from a thin wall gas vent 4" - 3" reducer and a 3" gas vent coupler.

The inside was smoothed with nothing other than duct tape to seal and eliminate the seam.

Then some very important pieces. The spacer between the box and the radiator support.

The spacer together on the box

The final assembly before sealant.

And from the inside

The baffle and snorkel will get held in place by sensor safe adhesive.

One thing not shown in the pics is that during assembly I had to cut an angle on the inside portion of the snorkel to clear the PCM.

very nice
you oughta dyno the car before and after

That's my very intent. At this point I'll dyno with the Volant in there after I seal it up then put the factory box back in and do another run.

Then some day when I actually have the cash flow to do the Corsa I'll do it all over again on the dyno.

That way we can put all the he said she said to rest and have pretty good real numbers.

Codewize, great to see I'm not the only one who had to modify/fix the Volant intake. I had to seal gaps on the other exit (out of the air box) tube with silicone completely, and what do you think of the crappy carbon look lid? Mines already all wavy, tried to use foam tape to seal it up. It's a temporary fix. At least it'll make a decent template to use to make the lid out of something else. Oh and you'll love how the computer sits in there, you'll have to slightly modify that bar too, you'll see what I mean.

Anyway, you'll love the sound at full throttle, personally I'm not sure if it really added anything else but sound. The exhaust you'll definetly notice.

Oh ya, I got all side tracked bitching about the Volant, I had a question for you codewize. Why are you doing all that modding to the air intake opening? You plan on running some sort of "ram air?" I guess that was 2 questions.

I already knew all the other stuff. I've had this box for over a year and it's been in and out of the car 3 times. However I'm glad you found the same problems and agree that they're designed like crap. I'm going to paint my lid body color and reverse the emblem to chrome with black letters.

It just took me a while to have the time to design and implement a neater install than what they provide you with.

No ram air. I did this because of the crappy way that the big huge worthless opening mated to the radiator support. It just kind of that there with no seal pulling air from all over the place.

So I did this based on the theory that taking air in an organized fashion is more efficient that just hanging out in the open. Plus the now 3" inlet is still just as large as the rest of the intake plenum.

Ya, they are designed for crap. Good thing as N* Cadillac owners that we are used to modifiying everything anyway, seeing as there isn't any real aftermarket out there.

When you do get it in, post again. Let me know if it made anything better, in your opinion. Seeing as you've had it in before you have something to compare it to, I'd like to know if you believe it improved anything, because then I might just copy your design, while I'm fixing/modifying that stupid lid, again. Thanx.

I was going to come back and post this after I had a day with the car. SO here it is.

When I originally got the Volant and installed it I felt like the car lost power. Everyone assured me that it was just the low end torque and that the top end was stronger.

After this redesign I have to say that the car drives 100% nicer than it did before. The low end torque is still there with amazing pull in the higher RPM's. That car still kicks at about 3500 RPM's like when it's stock but it kicks harder and pulls harder.

From what I can tell by the butt dyno it made a huge improvement over the factory box AND the stock Volant install. I will dyno the car with and without the baffle to prove or disprove this theory. I get 3 runs for the money so that's my 3rd run.

I personally look forward to your results. I just might have to use your idea, it's cool that your gonna dyno it.

Great job, codewize ! :)
Thanks for the pics :)

Nice job man! Can't wait for the results. Keep us posted.
