Thanks for your input Tony! Wow, so that's a completely different response than everyone else in the thread. So it's something I should consider then, and there really aren't any negatives? What about the throttle body? Would the setup gain enough power that it would be worth the effort?

I'd be running it on the following setup:
AES Forged LS6 346ci (tuned to 7k rpm)
A&A V3 Si (3.4pulley @12#)
Speed Inc SI2 Blower Cam (Mild)
LG Pro Longtubes
B&B Bullet Catback
OEM Heads/Throttle Body
638rwhp/550rwtq

 

Ok. For some reason I thought you mentioned you had a stock throttle body and I assumed an LS1.

 

You would want a ported 90mm OEM TB at a minimum or just step into a 102....if your tuner is capable a 102 will make the most power....its a little more challenging to tune though so make sure your tuner is up to the task

most anything that helps the engine breathe better NA will help it be more efficient under boost but what folks are telling you is that the bang for the buck is not there.

Hey tony,

are any of the "low profile" sniper style manifolds worth looking at for a street car on boost?

reason I ask is that I'm running an LS6 now and I'd like to add another set of injectors (primary pump gas, secondary alchy) and I don't know of a way to do that with the plastic intake.

I've seen some guys use the screw in alchy nozzle for direct port but I'm concerned about taping into the nylon intake.

 

i'm just stating my experience. also have a close buddy with a 416 f1x combo with a sheet metal intake that ran an 8.5 @ 155 with a 1.18 60' on the same day i blew my intake. this is after we pulled a **** load of power. car is a full weight c6 z06 with a 4l60 and a very tight FTI stall. i believe its a 2800-3000 stall (not too sure on the str but it drives amazing).

 

I've personally seen plenty of the older FAST intakes blow out the bottoms and even 2 FAST 102's blow the tops to shreds in one single day at TX2K in Houston. They weren't running anywhere close to 100psi boost, LOL. What's changed in the FAST design since the 102 was introduced to now allow it to hold 100PSI?

I would absolutely love to see one of these hold 100psi and would begin using them again if I saw that they don't blow at even lower pressures.

 

The older FAST pales in comparison in build quality and design to the newer 102 version....it's the proverbial apples and oranges scenario. In fact the new 102 design is 3 lbs heavier than the former 90/92 1st gen manifolds.....that's ALOT of plastic to make up 3 lbs and it is a much much better more robust design than the earlier version.

I would like to see a picture of a blown up 102 intake (that wasn't from a really bad nitrous back fire) and purely from boost pressure.

Bottom line guys....I have helped many hundreds of folks (potentially 1000 or so honestly) over the last decade and some change with these manifolds....I don't know of a single customer of mine that had one come apart.....not one.

If you buy a ported intake from me I will replace or fix it at no cost to you in the event you have an issue caused by BOOST (not a nitrous explosion which is violent pressure far exceeding any boost levels possible).

Im not concerned and neither should you be....the Internet can be a blessing and it can also be a curse....you have to learn how to navigate through the good (and the not so good) information out there. I have over a decade of real world experience to draw from regarding this specific situation....most of you reading this don't have that luxury

As I said....buy a ported intake from me and if your concern has anything to do with the quality of its construction and its ability to be reliable under boosted conditions you now have nothing to worry about....I will personally stand behind it in the event you have an issue even if FAST doesnt want to help.



Cheers,
Tony

 

I just got off the phone with Tony. Ordering a fully ported FAST 102 for my LS3 today. There is some discussion as to which will work best for my application after going over some details with him. He said he might go with the mid length runners in mine as we never see below 6000 RPM during a pass and the crossover point, power-wise, seems to be around 6500 RPM. Also, we're going to be passing a lot of air through the intake (~1200 horsepower worth of air) so that's going to lower the crossover point slightly as well. I'll let you know what Tony comes up with for me. Thanks again, Tony. I'll be back in touch shortly.

 

Done deal. Just got off the phone with Tony. He's going to go with mid length runners for my application after all. If anybody's on the fence about this manifold or anything else that Tony deals with, you owe it to yourself to call him and discuss it with him. This is Tony Mamo we're talking about here so anything he touches is really as good as it gets. I even got some T-shirts for me and the crew out of the deal. Does it get any better than that? I really appreciate all your help, Tony and thank you for being a part of our little street C5 Corvette project. Who knows where we might go from here now.

 

Outstanding, glad you got some use out of this thread, smokinstorm.

Phenomenal customer service and quality offer, Tony!

 

Yep. Right thread at the right time. As I stated, I was going to do this anyhow. It was just a matter of when. Tony tells me 20 to as much as 25 horsepower more vs my stock LS3. I won't need it right this second as I'm pulling power at first but plan on putting the teeny weeny F1-A to the test later on this year and the FAST 102 was going to have to be part of that equation anyhow. And there's no denying the "cool" factor of a FAST intake vs the stock intake when you pop the hood. I'm feeling really good about this intake right about now. I'll post up horsepower numbers when I get it installed and tuned but they'll be well over 100 shy of what my engine is capable of at first.

 

Hm,

So they DID change their build quality and design for some reason.

Very good!

 

This is so true.

Sometimes you can read between the lines.

Such as NW102 just can't hold the big boost.

Which should be well-known here. Or is it?

Sometimes the big build is for sale just after it was completed.

Or it never happened.

Just as FAST never cracked.

We'll never know.

 

I running about 10lbs of boost with a fast 102, mine has not come apart, with a ported tb. I like my set up better throttle response.

PS. My Fast 102 was RTV sealed all the way around. maybe this makes it better so there are no leaks.

 

Tony, if you will guarantee it to hold 30 pounds of boost I will take you up on your offer. Can you please PM me with detail? Thanks

 

Sure....done deal....will PM you here shortly

Regards,
Tony

 

I will put in another vote for the FAST 102. I have been running it with 22-25lbs for the last 2 years.

 

I'll add my $.02 to what this guy just posted.

He's run this setup over 250 passes in the last two years. Spinning over 7000 rpm on each pass. That's putting it to the test...

 

Y did u rtv seal it??

I hav a mamo ported 102 running 10'psi as well. No issues. Planning on upping it to 14. Wondering if sealing it is needed.

Tony what say u on sealing?? Did you seal yours ? Thanks will get around to offing a cam and yells Terra's shortly

 

No need....Its got a generous sized O-ring around the entire perimeter....save yourself the mess!
