Modified FAST install




As some of you recall from my previous post on the topic, the install was to involve all the areas of complaints associated with the FAST manifold and solve the problems so that the manifold can be installed with no modification to the firewall. The following areas were addressed since they were the most common complaints:
1- You had to cut the firewall and purchase some type of covering for the hole you make.
2- The MAP sensor had to be relocated to the back of the manifold and needed a 50 dollar extension wire to be able to make the electrical connection.
3- Many people didnt like the color of the manifold wanting a more stock look.
4- There were many complaints about previous models that leaked. While I have never seen one leak, apparently it had been an issue in the past.
5- The cost for porting the model, while not included on any intake was too expensive for many.
Cameron bought a FAST and had it sent to me for all of the above issues to be fixed. Total work time for the mods were about 4 hours including a mild port. The manifold was to be used with his stock heads which I wasnt able to convince him to swap out at this time. Porting an intake manifold includes port matching the opening of the manifold to match the shape and size of the intake runners on the heads they are being used with. Since this FAST was being used with his stock unported heads there was little porting needed and doesnt make any sense to pay serious money to have it ported especially if one day you were going to install heads with bigger intake runners and need it ported again.
This first 2 pictures are of the top of the manifold and as you can see Cameron wanted a gloss paint used so it always appeared clean and armoralled:


In this next one the back of the manifold was cut and a patch peice was attached using a plastic adhesive (GOOP sourced from home depot). In addition, the brake vacuum hose inlet was relocated and replaced with a brass fitting so it would fit. The manifold isnt resealed at this point and the top part is simply lying on the bottom shell to see how it looks.
Here is the cut" to the top half: the loop has the lip that seals to the bottom half still intact.

and from the bottom:

The orange you see in the seems is the original RTV silicone gasket which was resealed carefully upon reassembly:

This is the new home for the MAP sensor. The first picture is the outside showing the location which doesn't interfere with anything and the stock wire is plenty long. The second picture shows the inside of the manifold where the MAP takes its reading from. It isnt in the runner and it isnt over the throttle body where I beleive FAST recomends. Its very hidden and stock looking.


This is the manifold installed on the motor. It required LS1 o-rings to let the injectors fit the FAST. It also required oversized washers for holding down the fuel rail. Note the fuel rail covers fit fine after a slight reshaping with a dremel and 3 minutes time. The rumor that the fuel rail covers wont fit is a myth.

and overhead....

You can of course paint the cover any color you want. Semi gloss black looks the best but flat/matte black would simulate 100% stock.
In person the manifold looks like it has been armoralled. The flash of the camera seems to over-emphasize the shine.
The car is now able to break the tires loose on a simple roll in of the throttle where before it couldnt do it at all. The car was getting squirily while testing and the tune isnt done since it needs a wideband bung welded on. Once fully tuned I'm sure it will be an even better gain. I felt the FAST added more that the headers did, but they add power in different amounts at different rpm's.
The total cost of all of the above was less than 60 bucks in parts including the 0-rings. I tried to get the tune better but I hadnt told Cameron that I had a tragic loss just prior to the start of all this work. I didnt want to spoil his day but I will be out of commision for a while. I'm sorry if I wasnt my usual self joking around Cameron.
Cameron, drive safe and enjoy the car. Pay it forward and thanks for all the meals and the friendship. You Hoffie, Joel, and the rest of the Bellmore crew and a great bunch of guys. Hoffie gave me tires, you got a manifold, so just keep the wave going.
Thanks everyone for reading al this.

My sincere condolences on your loss.

p.s. now that I think of it...why didn't you post this before I went and put a cam in? I didn't realize it was that easy. I could have perhaps put a hurt on Dennis' 11.62 bolt on record run if I had the FAST!

but yet decided to move forward with the install without giving the slightest inclination that there was something wrong. I am truly humbled by this experience.
Many thanks again and hope that you overcome this tragic chapter in your life. If there is anything I can do to help or need anything please don't hesistate to ask.
