a properly ported Fast 102 will pick up near 25 rwhp in your LS2 car.dont install without porting!!!!!mine made between 55 and 65 rwhp with the LTH's depending on dyno car was on.

With the stock cam your gains from a FAST will be substantially less that quoted. After headers, the stock cam is the bottleneck, not the intake. Personally I got 15/12 from a FAST from a ported stock intake.
I prepared a thread with all my mods overlaid on one dyno sheet that you might find of interest.

If you do them out of order you won't be getting the gains you otherwise would. Your cam becomes the impediment when you remove the exhaust manifold impediment, so providing a more free flowing intake won't matter much, the cam won't allow the engine to use the potential additional airflow.
I don't recall seeing any dyno or track results for a FAST on a stock cam car in my 15 years here.... perhaps somebody has done it, but it's just not the best way to spend your money.

Personally I wouldn't bother porting my intake with a stock cam, see my reasons above.

Not with the stock cam. You have to remove the impediments to airflow in order - first headers, then cam, then FAST then new heads.
If you do them out of order you won't be getting the gains you otherwise would. Your cam becomes the impediment when you remove the exhaust manifold impediment, so providing a more free flowing intake won't matter much, the cam won't allow the engine to use the potential additional airflow.

Oh, and the cheapest mod will be the COW Booster mod. I think it's like $99 now and you can't get any mod that will change the character of the car like the booster will.
Say what you will about his advertising, his product flat works, it's amazing.
I did a thread on it as I didn't believe it until I got it.

And YES, you are right.... Clearly, you're the authority on the LS2 mods and you've got data to back it up.
I agree 100% with what you explained earlier.
Not with the stock cam. You have to remove the impediments to airflow in order - first headers, then cam, then FAST then new heads.
If you do them out of order you won't be getting the gains you otherwise would. Your cam becomes the impediment when you remove the exhaust manifold impediment, so providing a more free flowing intake won't matter much, the cam won't allow the engine to use the potential additional airflow.

In my business, we get tons of calls every day from people that read forums and want the same parts everyone else has.
Why I try to explain over and over again to people is that YES, you'll make some gains with the parts you want, but
you'll NEVER get close to what you think you're going to get (or what other people claim they got) if you don't do things
in the right order.
It's a conversation I have over and over every single day.... No matter what the topic or mods....
Your advice is SOLID.

.... and YES, you are also right again... The CoW BOOSTER! in NOT Chinese CRAP and it is AMAZING!

C6vette57 Thanks for your kind sentiment as well - I don't have a shop, but why don't you give Chuck a call. It's free, he has a lot of customers nationwide and I always say (to his face) that the man in person or on the phone is not what you'd expect. He will help you even if he doesn't make a dime and he knows his stuff.
You should note what he says above - he recommends parts be purchased in the proper order, he could probably make more money selling customers what they think they want, but long term it's better to provide guidance on what will actually work rather than just taking somebody's money.
Chuck by the way, I like your new smaller fonts, etc!

Not too surprising. LS6 intake is quite a bit better than the stock LS2 intake.
