LS6 vs FAST intake Swap
Evening,
Say I was wondering if anyone knew how many pony's I'd pick up if I swapped my Stock LS6 intake for a new 92mm Fast intake,
Or would that be just a waste or money ?
Also if you have any better ideas feel free to post them.
Thanks I appreciate it

You really need supporting mods to take full advantage of a FAST intake: heads, cam, headers.

LT's, heads and a cam first...otherwise you're just wasting your money. The stock LS6 intake is capable of outflowing the stock LS6 heads (unmodified). The intake is not the bottleneck on a stock set up.

Intakes are like other parts. Many times when added piece meal or one at a time, there are little if any gains.
But when every thing is added, from CAI though to exhausts, PLUS a great tune then it will come to life

Oh okay Now I understand, And it all makes sense, lol
Thanks everybody for taking the time elighten me on the intake swap.
So far i only have a 90mm throttle body lol I'm waiting till the car is paid
off in Dec 09 then I'll begin to wake the motor up with some mods,
Still trying to decide on smog legal supercharger or H/C/I & headers plus an increase in compression atleast 11:1 maybe more, also I plan to make the car Sub 3000lbs
All the Best and leave the rest,

Go to the TPIS web site and look at the dyno tests done with a variety of tb's and intakes. Even with the mods to their engine, a LS1 tb and an LS6 intake were not far behind the 90mm tn and a FAST. I wouldn't spend the money for a FAST until I had massive mods completed. Or, port and polish the LS6 and be happy.

I have a TPIS 78mm ported tb on a polished* but not ported LS6 intake. I am very happy.
the TPIS oval TB on a LS6 intake does VERY VERY well.
* smoothed out the ruff edges, but do not enlarge the runners
