I just order the vortex rammer. What is involved to install it? Will it affect my quarter mile ET? If so about how much?

 

if you need any install tips or get stuck just let me know, I'm always around my computer for one reason or another

 

Ditto what Scott said. I'm usually easy to get ahold of. The installation is very straight-forward. I did the Rammer box and the Power Duct at the same time. Haven't gotten back to the dyno yet, so I have no conclusive results on my Z06.

But this is a mod that even a novice "airflow engineer" ;) can see has to provide a benefit over the stock air inlet system. Looking at the install from under the car you can tell its got to pull significantly more air than the stock setup.

 

I got an honest 2.5 tenths out of it (same weather). :yesnod:

Also, my trap speed went from 109.1 to 112mph.

 

I will post my install pics when the member pages is back up, or just search for posts under my name in the archive when it is and keywork my name with vortex install.

:seeya

 

measure twice, cut once!! :yesnod: :yesnod: :yesnod:

 

I used a Dremel to cut my shroud while it was on the car. I wasn't too pleased with the job I did, but unless you get under the car, you can't see it. this is definitely one of those mesure twice or even four or five times before you cut once deals. One other thing, you might want to use a little silicon spray on the posts that hold the air bridge on to the shroud. They can be a bit tough to get back on dry. Have fun! It's going to feel and sound better. :jester

 

Ryan Bell, just a curious which is faster in 1/4 your 355 or Vette? ;)

 

I used a razor blade knife and it was very easy. The shroud is just plastic, just press the knife through it, then just go down and over. I have a dremel but it was easier with the knife

oh yeah, dyno showed 13/14 gains from the Vortex and airbridge

I found the install fairly easy. Didn't care for the template, though. I mounted everything first, marked the holes for the airbox, then removed and cut the shroud using a box-cutter.
Can't give a 1/4 mile time, but on my first trip to Willow Springs, without the Vortex, after exiting turn 9, I would accelerate to 125 before braking for turn 1. Second trip, with Vortex, I would accelerate to 135 between turns 9 & 1. I would guesstimate 5mph was attributed to the Vortex, and maybe 5mph to getting off turn 9 a little better and shortening my braking zone by about 75'.
I do feel the Vortex did make a noticable difference, even though I couldn't feel it by the SOTP.

 

I'm with 2KFRC5, except I also used a Dremmel tool as mentioned above. The Dremmel cuts through the shroud very easily and, in fact, so easily that you have to be careful that it doesn't pull away from you and make a poor cut.

As to the strategy for how to mark the locations for cutting the bolt and box holes, there have been several people post that when using only the template, they marked their shroud, cut it, and then when it came time to bolt the new air box to the shroud there was difficulty in alignment or getting things to fit. To avoid these problems, I also suggest going with 2KFRC5's solution. :)

You'll see in the kit that the Rammer air box has a larger top portion and a lower smaller portion that includes a downward protruding lip. I left the lower smaller portion off, but assembled everything else and reconnected the entire assembly to the engine (i.e., to the intake manifold). Then, lay the new air box on the shroud in the position where it ultimately will be bolted to the shroud. Next, use an appropriate marker or tape to trace around the air box and to mark the bolt holes. Then remove the air box from the shroud, and the markings you made provide a guideline where to cut your bolt holes, and also where to cut the larger square hole to accommodate the lower portion of the air box.

Hope that helps. :cheers:

 

I haven't run this F355 in the 1/4, but if it runs the same as the last one, it's a hair quicker (12.7@113mph). It's almost too close to call. :D

 

That is what I did, I put the filter in the box top, the MAF on the filter, then the powerduct on the MAF and connected it to the intake. Then I drew with a pencil around the box top and made marks where the holes were at. Removed the setup and turned over the box, took a piece of carboard and cut it to fit exactly inside the box(this is how big the hole needs to be). Then measured the distance of how wide the plastic is on the box where the holes are(1-1.5 inches) and then did the same on the shround. Made marks on the shround and then placed the cardboard cutout on the shroud, drew around it and now you have the hole to cut out. Took the box cutter and a minute later put it all together.
