i am going to get a cam in my 2002 trans am. looking to get 400rwhp. is getting a fast 102 & nick williams 102 throttle body worth the money. will it get me any more horse power?
Thanks

Of course it will get you more HP. Anytime you can feed the engine with more air, that equates to more power. I'm sure down the road, you'll add heads too, so having the FAST 102/102 combo will be a good investment.

Sure the FAST 102 combo will produce more power on a cammed application, however you might be better served spending the money on upgraded heads (there's generally greater power upside from upgrading the stock heads vs. upgrading the LS6 intake to a FAST setup). From a cost standpoint, a nice set of budget heads should easily get you to and beyond your power goal and it would be comparable to the FAST setup.

Unless you open up the heads and do a cam swap...a FAST 102 will likely not produce any worthwhile gains over any other FAST or a TPIS 90mm LS6.

By worthwhile you have to look at dollars per hp...and a FAST 102/102 is gonna run you well over a grand.

By comparison my TEA CNC 241's with springs, setup, and shipping were just over 1100 and you'll be setting yourself up WAY better investing in a quality head now vs. the FAST 102/102 now.

Once the foundation is there...sell the LS6 for 350+ dollars and then a FAST will only be 350-550 out of pocket.

I agree a set of heads is needed.

My buddy's car just picked up 20whp and 28wtq with a fast 92 and ls2 tb. His car has stock 243s that have been milled to 59cc, flat top pistons with valve relief stock crank and rods, and a mild cam. His car is rediculous, makes 476rwtq and 468rwhp. The tq is phenomenal on his car.

With a good set of heads I have no doubt he'd be close to the 500 mark on both tq and hp

I'm wondering how much HP/TQ the FAST 102/102 will be worth on my combo? I made 415rwhp on a stingy dyno with the mods in my signature, which include a stock LS6 intake and stock, unported TB.

15/12 peak. Possibly closer to 20 under the curve in tq.

I've personally witnessed a 13 hp gain from a stock LS6 intake to a stock FAST 92. This was a HCI LS1, and done on the same dyno about a week apart. I cant imagine the 102 making but a couple hp more

You'd think there would be more going from stock 78/78 to FAST 102/102.

LS6 flows better.

I saw in a magazine article with the stock cam and heads the FAST 90 (original) picked up 10HP over the LS1 and like 6 over the LS6. FAST 102 is better than that and with more airflow demands, those numbers would grow. Plus, the LS6 intake is better than 4HP over an LS1 on most head/cam setups. Probably closer to 10-12HP. FAST 102 would be that much better than an LS6... especially as airflow demands increase.

Getting the manifold port matched is another way to bump up power. I was told it could be another 5-10HP easily vs box stock. By three different vendors.

So now the debat arises; FAST 102/102 or FAST 92/92? I'm sure the 92/92 combo is cheaper and easier to find used.

New, the difference in price isn't much. That's why I did 102.

Either way, port-matching it (not sure what "porting" does) would be worth a little more.

I personally made 20rwhp going to a 92/92 with a DIY port and port match. To get the most out of them you can't ignore everything north of the TB. Get a 4" bellow, 90mm MAF or SD, matching lid and of course a tune. This was on a car that already had H/C.

I picked up 12whp and 15tq going from an ls6 intake to a 102/92 combo with a baby 226 cam.. That was without a retune for the intake just on the dyno to see gains.

The 102 won't make much if any more power than a 92... It will almost always make more torque.
