Intake and throttle body recommendation question

Okay HP guru's...

My set up will soon be:

LG headers w/ hi flow cats
EG Whiplash cam
worked #243 heads

Already have Vararam CIA and Ti catback.

To gain as much hp as possible, should I go with an LS6 intake (sitting on garage shelf)

OR

Purchase a FAST intake ?

With all this in mind, this is my DD and weekend warrior car.

Suggestions / Recommendation ??

How much do YOU think you will gain with the FAST? Divide that by the $ spent and decide if it is worth it to YOU.

I like my FAST 92. I went from my LS6 to the FAST in my cam only 01 and felt a very nice gain over the LS6. I dont have any numbers right know because of my clutch but the cars pulls alot better than it did with the stock manifold.

I have the fast intake and ported fast tb to match. Very good breathers. If money is not a big factor I think you will be happy with the fast. Gives room to grow also if you get different heads etc.

Money is somewhat of an issue, but not that much as I know parts for these LS based motors still isn't cheap like the old school chevy's. And yeah thats another reason I'm looking at a FAST, room to grow.

Put the LS6 intake on, and get a 3.90 or 4.10. You will see a bigger improvement than the Fast!

My Set up

I just got all my parts to do my car. Unfortunately I have Pneumonia right now so I havent got to start on it. Stephen likes the 102 I have. I purchased the Whiplash and Trick Flow 215 Heads along with a Textralia clutch and an RPM Stage 2 410 gear package.

Old school, get a tunnel ram with a nice fat dominator sitting on top.

Just kidding. Gears are nice as stated earlier if you do not plan to go turbo or blown.

My goal here is to get as much HP at the rear wheels as possible N/A.... and then put a ProCharger on it !

If that is the case, skip the FAST and put that money towards the Centri. Boost on stock a intake is just fine.

Seems you have conflicting goals. Going for the most HP N/A, will make your cam/heads, and compression ratio choices very different .....then going FI.

You know, I never thought of that. For boost I'll need different comperssion chambers on the heads.

Well..... Looks like I have some decisions to make..

Thanks for all the input guys.

Yeah, it's kinda two different paths. If you want to max out the HP N/A, you will be going the FAST intake, 90mm TB, radical cam, high compression, etc. You have a six speed, so there is a lot of latitude for cam selection.

If you stick with a reasonable compression ratio, on a good set of heads, and an England Green cam, you could easily transistion to FI. Granted, you won't have maxed out the HP N/A, but you'll have a healthy platform to bolt the SC onto, and then enjoy.

If you have stock heads/cam, a low boost centri will be fine. Now if you have higher comp ratio than stock you have to be more careful.

If you want to really turn up the boost, you will need lower comp ratio or racing fuel/meth to keep things together.

Many LS motors are making big numbers with LS6 intakes and stock throttle bodies. Makes you have to consider what the FAST is really worth. No doubt it has high flow "capabilities", and many will say that it will allow for great HP gains. But, You really have to consider how much air your engine really demands.

You might have been better off investing in aftermarket heads like AFR, etc...

Given the options you mentioned, I'd say install the LS6 and then start playing around with a ProCharger.

Good luck.
