    Fast 92mm Intake and TB

    I have a 2000 WS6 with SLP LS6 intake, LS6 Ported Heads, Comp Cam custom grind cam and 80mm BBK Throttle Body. My question is: Is it worth the money to install the Fast 92mm intake and TB? What will I gain with the 92mm instead of the 80mm? Will I need a new tune?

    I asked the same question with my current setup to a very well known LSX performance shop around here and they told me that it's not really worth it for us stock displacement guys. They said they were only seeing a 5 to 10 hp gain on the dyno with stock displace engines over the LS6 intakes.

    Oh and I am currently making 365 whp and 373 ft-lbs.

    Check out the new GM HIGHTECH MAGAZINE, they installed one and had nice gains after the re-tune. 20+hp I believe on a light mod car.

    I recently had my car in the shop for a head swap and a ported FAST 92 setup. I went with a budget head and was most concerned about building power throughout the entire band (wasn't as interested in a big peak numbers as I was in power under the curve). After the install, I netted an additional 45 rwhp and 20 TQ. While I can't speak as to what part of the gain was attributed to the heads and what part was attributed to the FAST setup, I gather that both yielded a nice power increase.

    I dunno, I swapped out a Gran. 85mm MAF and went back to stock MAF, installed 42LB injectors, and a Ported/port matched to heads FAST90 w/ NW 90 TB along with retune and picked up 51 RWHP and 27 RWTQ. But there are too many factors to say that the 90/90 did it for me. It could have been mostly in the tune. But overall it was still worth it for me in my opinion.
