Default is 90/90 fast worth the money?

ive got an ls6 intake manifold and a ported TB...(ive got full bolt ons) soon ill be getting AFR 205 heads with a pretty big and aggressive cam. Ive heard mixed results about getting the fast setup if its worth the cash. I mean how much more gains will i get with the fast setup?

Where's the search button director when we need him

Ive probably personally written enough on this topic to fill a small phone book.

In short, an out of the box FAST 90 will be worth 10-12 ponies....a properly ported one about double that.

If your looking for all the money from your combo those are serious gains to leave under the table. Based on the few parts you already mentioned it looks like your trying to maximize your set-up so its a no brainer.

Seriously....do a search and be prepared for alot of reading if your looking for a more detailed response.

Call or PM me if you would like some help with your combo or have questions concerning the induction set-up....

Cheers,
Tony

My quote above was focused primarily on the addition of the FAST 90 intake....not specific to 90mm TB's.

But while we are on the topic the NW TB is a really nice piece and works well....the FAST TB's have had their share of issues in the past (the blade sticking being the number one complaint).

Well it all depends on what setup your running. Look at my set up. Im hopping to hit @420-440rwhp with my heads and cam set up with an LS6 intake, the cam will be a 228/228 .588 .588 on a 114 with all bolt ons. My over all goal is to hit right at or just under 600rwhp with NO2 because thats when Ls1s start to get shaky. So if I can hit 440rwhp and put a 150 shot of NO2 that will get me to my goal of 600rwhp. Now if I were to go all out and buy the Fast 90/90 combo and have it ported I might be able to hit @460-470rwhp but, once I put the 150 that will take me over 600rwhp for sure, so I will have to pill the car down to 100. You see for my set up its not worth sending over 1k on an intake because im going with NO2 so I dont need it. Now if your going to be N/A all the time then yes, I see you getting it.

I have a Nick Williams which is a really nice unit that uses the LS1 motor and TPS from the Vette. Hard to find now since he doesn't make them anymore but they are around if you keep your eye open.

When I had my heads & cam package done I went ahead and got the fast 90/90. My origional rwhp through a 10 bolt was 347. After LG got done with my set up, through my Moser 12 bolt my rwhp jumped to 467, torque is 428rw. Note that nothing is ported, I am saving that for post deployment to Iraq. My mods are in my sig.

Also, idk what my #'s would have been with just the h/c with the stock intake, or what the #'s would have been with the Fast 90/90 w/o the h/c. Hopefully someone here has done the Fast 90/90 to a stock motor. I did read in a sticky that someone did a dyno with an unported Fast 90/90, then pulled it off, ported it and redynoed it. I believe the result was no significant change in rwhp.

Two key facts to consider here...

One is obvious....who did the porting on the FAST and what type of R&D has he invested in the changes he has made....essentially how extensive (and effective) was the porting work.

Two....A stock engine would see less of a gain from the ported FAST (vs a stock FAST) as a weaker manifold will have an easier time keeping up with a 230-250 CFM intake port. Put the same two intakes in question in front of a 300+ CFM intake port and the delta in net flow will increase creating a larger gap in net airflow and power comparing the ported piece and the unported piece (if done properly).

I put a stock fast 90 and NW 90 on my cam only 346. Gut feel is I lost some down low but the mid and top end feels strong. I have underdrive pulley and cutout and catback. I removed my lid and long tubes for turbos. I didn't have the headers on though or the lid when threw the fast stuff on there. I also have a b1 cam in there still not the gt7 in sig.

My goals are to build a 408 minium possibly a 427 and then figured the fast 90 should work good for me. I like the direct port options on it also. I realize it may not take boost past 20psi but have no intention of going that high on boost.

Put a FAST 90/NW 90 on mine just recently. Before I put down 421/379 with a LS6/Shaner TB. I also installed a 12 bolt at the same time. Same dyno/same time of year I ended up with 435/389. So I picked up 14/10 through a 12bolt. I'd say it was worth it. Plus when I'm ready for a rebuild, I'll have an intake ready for bigger cubes.

This was a non ported one also.

IMO do the FAST 90/90 last. As for is it worth it, I don't know, its up to you and what all you have done. Suspension mods will help a ton too...
