Can someone tell me where is the best place to get the FAST intake? I have already had cams, headers, and a tune and would like to add this intake on my '06. I have read alot on this forum about it and feel like it would complete the mods I have so far. Thanks in advance.

 

Unless your C6 is supercharged, your power gains may be minimal compared to expenses with Fast, Lingenfelter firewall kit and labor. Better check with tuner on advice.

 

Fast Intakes are great with other mods, but there are collateral costs as well.

 

Can you explain? This is my first Vette and am trying to learn the ins and outs of modding them. Thanks.

 

Same answers everytime from the people that dont have one.....

I do have one and had it before the cam and headwork and it made a big difference. The re-work of the rear firewall was minimal and the install took about 3 hours. I would do this one again in a heartbeat.

 

Texas Speed and Performance is having a sale still I think for the Fast 90. For best results get the Fast ported.

 

Just for your info., Rev Xtreme ported the stock intake of a C6 and made a sufficient amount of hp, I believe between 7-10hp and it's not costly. That's probably what you would get out of the FAST 90. Rev Xtreme is a Forum Vendor. You may want to give them a call.

 

Guys get over 20 to the wheels with one guy that I know of on LS1tech getting 27rwhp from his ported FAST. Like heads, a FAST makes even more power if it is combined with other mods that increase a cars breathing needs. Totally stock cars get around 12rwhp but future upgrades like heads and cam give more improvement if the manifold is there. The gains on the LS2 and H/C have been shown to make a bigger improvement than the LS1/6 did with the LS2 intake manifold being the worst yet from the general. LG got 20rwhp unported. When talking about what you think a part does it would be best to mention the source of your opinion so others can scrutinize the data for themselves. I will go by tuner recommendation.

 

I have Fast on my Procharged 05 and would not do without, but if my car was stock I would ask tuner about potential, actual or guaranteed HP gains and then decide on cost effectiveness.

 

SpinMonster,

It has been proven that a FAST 90 without the aforementioned mods will not make the claimed hp as advertised. It needs to be enhanced by other components. Now, since you've chimed in on this topic, what gains you have personally you observed with just the FAST 90, that means no mods? There are people out there that would like to install the FAST 90 without any mods and expect tremendous gains? It has happened after talking to a tuner who installed same and ended up with minimum gain. And actually, I was only speaking about the ported stock manifold without mods when compared to the just bolt-on FAST 90 without mods. As of today, I have know additional info. about the ported stock manifold with other performance applications as far as horsepower gains. But when I discover that info., I will most definitely post it. Hence, I am not knocking the FAST 90. I thought that's what we do on this Forum, make comparison not criticize. Enough said..

 

Spoken like a gentleman.

It absolutely has not been proven unless you mean 20rwhp on a stock C5 since the use on the C6 has not been advertised by FAST. While I agree that there are few examples of the intake not yeilding any gains in rare circumstances, the data suggests that is a 1 in 100 instance and not on a stock car. Prior info on this topic doesnt agree with your statement and that it requires other mods to the car. Tony Mamo has repeatedly posted on this topic and not being a FAST representative I credit him when he says that the stock/unported FAST repeatedly yeilds 12rwhp+ on stock cars. A search on LS1tech will net many individual examples of how this intake wakes up the car. You will note that without exception, all the bashers never had one. The ones that have it like it. LG has gotten 20rwhp with it recently again. Mine is ported on a modded H/C/N20 car so I can't speak for other set-ups. Since most people getting it will have other mods, it would be wise to expect more than 12rwhp. I have seen as much as 27rwhp ported in conjuntion with a H/C package. In view of the mod's increasing returns in proportion to other mods, it is a bargain at 20+rwhp for the 760 bucks it sells for. No different that the 9rwhp you get for a 280 dollar pulley or zero hp for a 1200 exhaust or zero hp for a 400 dollar air cleaner.

So my input is save a few hundred, skip the exhaust, and get the manifold.

 

SpinMonster,

I agree on the 12hp gain with the FAST 90 and no mods. A tuner, name undisclosed for now, gained 7 hp by porting the stock manifold with no mods. The cost was less than half the price of the FAST 90. Wouldn't the porting have the same affect as the FAST 90 with mods?Just something to consider, when you are going into the pockets.

 

The FAST seems to respond better and better as you have more air demands. There isnt much data available for the stock unit ported but in factory form its terrible.

 

Check with Jeremy at Rev Xtreme. He has experimented with the porting and made noticeable gains.

 

I was going to add the Fast intake with firewall mods to my Z51 with Procharger, but after I saw the results from a Z51 with the same Procharger and Fast intake added, I decided not to do it. He payed large amounts of money to add the intake with larger throttle body and firewall mod and got only 12 RWHP more than my car. I would put the money in other mods.

 

REPLY: Be prepared for more noise from a FAST Intake in operation, since youre cutting into the firewall ; i tried cramming some foam rubber between the firewall and FAST but it didnt help at all. It will sound like marbles bouncing around except its more muffled. Im having it taken off this week and going back to stock. Mine is for sale , cheap, with just 100 miles on it.

I don't have any noise with mine at firewall area, but I do hear ProCharger and KOOKS.

 

How cheap

 

How much?

 

Prior to the FAST intake, My C6 6sp Z51 made 410RWHP/384RWTQ on A&A corvette's dyno. After the install, It made 427RWHP/405RWTQ. But really it's the power under the curve that you feel. I felt it was worth the investment. The car feels strong and pulls hard all the way to the redline. I'm now waiting for my ET heads to arrive at A&A. I'll take either the 215 or 225's. Either one will work well. BTW My cam isn't very large, 224/228/581/588/114. So I was really happy with the power it made. This is a perfect time to do this mod. I've got 31,000 on the clock. So new heads, pushrods, and throw in a new set of OEM lifters,and it kinda freshes up the motor. And the power increase will be nice. It's a daily driver.
