I understand there will be a small amount of prep work (drilling a hole, and removing a little tape to to gain a little extra length for a wire to connect and that is about it) I should be able to shed some light on this after this weekend.
No issues for clearance of the firewall which is very nice!

Since then, I have installed heads and a cam, but I still have the ported FAST 90. Heads and cam gives me 488rwhp/450rwtq on a mustang dyno through 3.90's.

Thanks!
Just dynoed my LS2 w / FAST 102, Stock heads, and cam. I plan to go to the track soon and will post results.

Fits perfect, easy install.

Not sure when I will be able to get dyno numbers as my tuner is out of town this weekend..
I have the same set-up...no ported TB...I'm eagerly waiting for your results...

I would suggest getting to the DYNO and get some base numbers. Also
A Pro Tune will be necessary to see 400RWHP +
As far as track times LS1Lt1 and Dennis NJ have gone into the 10's. But thats not the average. 11.40 with a good set of tires and a reasonable 60'.
when do you plan to have the install completed?

I just did mine last week, no firewall issues and the fit is perfect...

However, if you have milled heads you need to check the clearance to the valley pan. It comes with 2 little rubber bumpers to put on but when I noticed that when torqueing it down that it didn't feel right so I pulled it back off and and sure enough, they looked lile they might have been touching from the marks on the valley pan. I used some clay on the bumpers as well as all the port contacts just to be sure and the bumpers were definitly hitting.

For some stupid reason, they dont come with manifold gaskets so make sure you order new ones, the directions say you can use your stock ones but mine were all stretched out and wouldn't stay seated while trying to put the manifold on.
I talked to the vendor about the gasket issues I was having and he said that sometimes they work and sometimes they dont... I can't believe that with the money these things cost that they dont give you new gaskets!

Oh, one more thing, they do give you new oring gaskets for your injectors, make sure you use them. I thought they were in there for due diligence sakes and since I had new injectors and they all still looked new, I would opt to forego changing them. IDIOT!!! I had little micro leaks at every injector port. It was kind of hard to diagnose too since using the old starting fluid trick to find the leak didn't seem to give any feedback... When I finally figured it out, I realized the orings are actually bigger for the FAST 102mm than they are for the 90mm ... I know , I know, I'll follow the directions next time.

Hope this helps someone...

Instal went smooth, took my time and enjoyed the process...I bought the FAST gaskets and opted to use the o-rings for the injectors (sounds like that was a good thing reading Isaiah48 post) fitment was very good and boy can I tell a difference!
Unfortunately I am waiting on my tuner to free up some time to clean me up as it feels like I am lean above 5k rpm's so I will have to get re-tuned before I can strap it down on the dyno or go to the track.

We played with the tune for a couple hours yesterday, the car is pulling some serious air considering I still have the stock cam.
getting the AFR happy was easy but the timing has its challenges.
Might try a colder and or diff plug to see if it will help as there is a "spot" around 4500rpm's that isn't cooperating with us.

I had to lower timing between 4,200-4,800, I go from 28 degrees before and after that area, down to 23-25 degrees.

I had the same issue with my FAST 90 so I'm not sure what is causing it, but I sure would like to know. I tried moving when my Power Enrichment comes in down to 3,000rpm and upped the PE fueling in that range as by as much as 15% and like I said, I'm still at 23-25 degrees...

Let me know what you find out if it doesn't get resolved in this thread...

~24º is pretty good, and typical for Gen IV LSx engines at MBT (max brake torque). I think for the amount of air being moved, though, the TR5 plug just isn't cooperating at the cylinder load being seen.

Either way, you should never run a static amount of timing across your WOT area. If you do, you are lazy. Timing should go down as cylinder load goes up... MBT happens at peak cylinder load, and since cylinder load starts dropping as you approach redline, you should start adding more timing. I typically shoot for 24º at MBT (usually around 4800rpm) and 27º at peak horsepower, which can vary... but usually about 6000rpm for stock cam vehicles.

Hey, Got a question for you. On your FAST 102 install was there a hole up front for you to mount the MAP Sensor ? Sounds like you guys are really
nailing down the A/f and timing down. Usually you don't have to mess with the Plugs. Just my 2 cts.

You have to drill a hole either way. They are both shipped plugged so you can decide which one works best for your vehicle.

Check out what I found looking around....pretty cool. Lists all the parts you need.
