Who has the best deal on this product? From the threads I have searched it looks like you need a MAF wiring kit and a firewall kit is optional? I would like to buy it ported if possible since that would be the easiest, or not as i could ship it out for porting.

Thanks

 

ebay

 

A ported intake will give you as much power as a Fast intake for less money.

 

The ported intake is great and gives more bang for the buc.. but it does not make as much power.. a ported fast will produce 20+whp compared to 10+whp with a standard port. That extra 10whp will cost you an additional $700 dollars compared to 10 for $250 so clearly the stock ported piece will keep some money in your pocket.

 

Just to add some info....when I went from my stock intake to FAST intake, I gained 16rwhp, pretty good, but expensive. I didn't do the "kit" for the firewall, but had my shop to a fiberglass patch after the cut and the fuel rail was altered rather than pay for the FAST brand. Even with the $$$ saving corner cutting, it was still expensive for the HP. The earlier post is correct, though , the best deal is on the 'bay....I got mine for 1/2 what some are charging.

 

so is any fast intake on ebay good for the ls2?

 

90mm LSX....was made to fit Ls1/LS6, thats why you have to cut the firewall on the C6.

 

as long as its the Fast Lsx intake. make sure its 90mm, since there are other sizes, but they wont fit the ls2

 

I gained 15/rwhp and 15/rwtq with my ported intake. Pretty good for $225.00.

 

Thats what I have seen as well.

I am giving CH harris a try

 

Me too!!

 

On any given days the same motor and dyno numbers can change due to temp and humidity along with + or - error. You wiil never get as much power from porting stock as compared to FAST 90 as proven recently by LG Motorsports.

 

Hi guys...


It's true that the currently available ported stock LS2 intakes are not as strong as the FAST. I've got some development going to try to close the gap a little more... but not sure if its honestly available in the "casting" ("molding" sounds so lame).

You also need to look carefully at dyno comparisons. Not all are as clear cut as they seem. And remember, a volume FAST dealer gets good pricing and makes more money on the sale of it so there is a incentive there to downplay the ported LS2 more than it deserves. Likewise... shops make sales from the biggest power headlines. That naturally makse the FAST more attractive as well.

Anyway.. the FAST is still the top dog. The ported LS2 is an affordable alternative that gives no warranty or fitment hassles. Both get you more power than stock. The more expensive one makes the most power.

 

And won't require the kit to make it fit!

 

I have read some comments that say the FAST really excels in strokers or supercharged engines that can take advantage of the larger intake.

Your right, dynos will not tell the whole story. I tend to look at mid range increases in TQ and HP before peak power increases for sure.

 

Also, when comparing dyno results, it's important to look at the entire curve, not just the peak TQ & HP numbers.

 

All of the FAST intake manifolds that we have done on the C6 Corvette's have really gained a lot of HP and TQ. Not just peak to peak numbers but all the way through the RPM range. Not only that but you are gaining a solid 18-26 rwtq through the middle of the RPM band where you are going to feel it on the street and the track.

While it may take some work to install it, it really is a worthy modification.

 

The FAST is a great mod you will not find anyone that has one that doesn't love it. As for CHarris85Vette I agree the ported LS2 is an affordable alternative but as for "you also need to look carefully at dyno comparisons" the same could be said to you about switching from stock to ported stock.

 

Jesus, it never ends.

Does anyone ever use the search feature?

OK rant over so on to the good stuff: You are 1000% wrong and its not even as good a value.

Here is a comparison of the PORTED FAST vs. a PORTED LS2:
bottom line is the great ported LS2 top line is a ported FAST


Does that look even remotely close to you??? Why does everyone insist of making comparrisons of these things by quoting peak HP only? The midband gains of the FAST over the LS2 are an additional 20rwhp and the TQ gains down in the midband are even sicker.

In the above graph the only difference was the manifolds. 9rwhp and 17rwtq is the difference if you mistakenly reduce the numbers to what is at peak. At it highest gain it is 20rwhp and 25rwtq OVER the LS2 and I would pay another 500-700 for that much. The power differences in the midband are staggering by comparrison to peak numbers. The top line is the FAST and LG headers with a tune and the botom is a ported LS2 with no other changes.

Some will still say the difference is "only 9hp" when in reality the above graph tells a very different story at 5000rpms. A ported LS2 is an accountant's choice, a ported FAST is a mechanic's choice.

 

Put headers on the ported intake and see what it gets. Let's compare apples to apples.
