Well my Vette is an 04 with 1500 miles on it and it doesnt have any other engine mods nor do i have any plans at the moment for any. I am planning on keeping the stock MAF. The only other thing Im adding is the smooth coupler. Hopefully I wont incur any of the mentioned problems...I have heard good reviews from people who have it. I wouldnt expect to have it run at less than new standards.

 

I'm glad it's working out for you. Just to ease my mind and refine my dataset, would you mind doing one thing for me, next time you're out?

Drive at around 2,500 rpm (maybe up to 3,000 rpm), steady state level ground, any gear, but preferably 3,4 or 5th.

Ideally just below 3k in 4th, if traffic permits.

Then, mash the throttle, and tell me what it feels like right at that point.

Smooth, linear pickup? Or maybe a little hesitation/bog?

I'd be interested to know, -- thanks.

 

Go to Home Depot, Lowes, or AutoZone to get the weatherstrip for the hood seal....much less expensive!

 

are all twin flow's identical to each other? Does one mfgr's model converge the two pipes differently than the other offerings?

For those of you not having any problem with your twin flow setup, how about letting us know the manufacturer of the one you are using?

 

different manufacturers products do look different...i checked most out when i was looking and settled on the chrome Dual Flow from West Coast Corvettes. It is supposed to be delivered Apr 1st. I am looking forward to putting it on and seeing how it runs...although now some of these posts have me worried that Its not going to run as well with it on LOL

 

I could be wrong, but believe the ones WCC sells are made by RM Racing.

I had a Halltech T1 (with the big airbridge) on my car before.
I removed it and put on the WCC chrome twin-flow and a chromed stock airbridge, thinking I'd lose power (was doing it for a show upgrade)...but I actually noticed a gain in both throttle response and power immediately after the switch.

I have no hesitation/lag/stumble at any rpms...but I do have the MAF screen intact.

What I've stated is my personal experience...and although I do realize other's experiences may vary, it seems the only people shouting out against this setup here have probably never actually used one....they are just recycling a very old internet rumor.

I would not hesitate to recommend this setup to anyone.

 

i have a twinflo with no screen but i have no hesitation at all or any stumble

98 vert with 6 spd
i do have a lopy idle

but whos to say what thats from
if somone wants to send me a stock maf ill hook it up and do before and after with no screen or with screen

actually that could solve all this hoopla once and for all

whos got one

 

I'm glad to hear some people have had good experiences with it. Hopefully I will have the same....I chose the WCC Dual Flow for show reasons also and I am using the stock MAF, so hopefully I will have good results also with no problems....

 

just lie some paper towels on a towel over your filter close hood an wash your car if you dont have hood seal towel will ring wet from water running down hood i did this then bought seal an even paper towels dry as bone wet filters cant help anything

 

Honestly i bought one off of ebay, and i have been happy with it so far. It seems like i have gained some power in the top end, but i have no ''real'' proof of anything. The filters are weird though, they also have an opening on the top for airflow... Anyone have any real proof of a gain or loss with these intakes?

 

I've had mine for a year!

 

I have had two versions of the dual cone setups. Both came with different sized K&N filters, and they were constructed in a different manner.

The first system I tried was in the shape of a "T". I don't recall the manufacturer, but it's Mid America Motorworks part number 603-888. I found that system to be a tight fit, and the plastic tubes were surprisingly heavier than I expected, which kind of concerned me since they were only supported by the clamp on the front of the MAF.

The second system I tried, and still use on the car, was Mid America Motorworks part number 612-006, which is actually manufactured by Granatelli Motorsports. I decided to go this route mainly because at the time I had just installed a BBK 80mm throttle body, which uses a spacer that pushed all of my intake components forward, thus causing my orginal "T" shaped intake to jam into the car's front frame. The Granatelli intake is "Y" shaped and also comes with an enlarged (plastic) air bridge, which is roughly a third bigger in size than the original stock air bridge. For my needs, the Granatelli system fits a little better and I can access the filters easier. Plus, I love the "fork-tongue" look of it under the hood.

A comparable system to my current Granatelli would be the Volant system. Not sure if I spelled that right. But the Volant system is also "Y" shaped and comes with its own air bridge. But I don't think the Volant uses K&N filters...it uses blue colored filters instead.

The "T" shaped systems claim 14 hp gains, while the "Y" shapes claim between 16 and 18 hp (if you believe the manufacturers).

This is a little off topic, but I did think about the Vararam once or twice, but I liked the looks of the twin intakes so much more. Since the filters on the Granatelli sit almost directly behind the fog lights, I simply installed a set of modified fog light covers that allow air into the engine compartment directly in front of the K&N filters on the right and left sides. I figure that's my version of the poor man's Vararam.

 

I liked the looks of the T or Y setups better than some of the other systems too. Since I show my car, its worth some of the horespower trade off.

 

I'll try anything............once!

Chas.

 

Tubes... WOW !

thanks much for posting your experiences.

 

My twin flow was made by RM racing.

 

Mine from WCC is supposed to be delivered tomorrow, so I am really looking forward to installing it! Just in time for a Poker Run next weekend...

 

I have to believe that the "surging" stories with these twin flows are an old wives tale (unless someone made a lookalike that had problems). I've had the RM Racing unit almost since my car was new, and I've never had any problems on the street or the dyno. I also seriously doubt that GM would have licensed this setup if it caused problems.

FWIW, I was also concerned about water soaking, so installed the hood seal at the same time. Everything stays clean and dry.

 

I've had 3 C-5's and I put the Twin Flow Intake and the cold air screens on all of them.

Between all the C-5's I've put over 160,000 miles on them and never had a problem with rain.

I do reccommed the cold air screens to feed fresh cold air directly to the filters.

If you want to save money and time, just drill about a dozen 1/2" holes in the soild black plastic that is removed and replaced with the cold air screens. That's what I did on my 3rd C-5. It is the same concept that GM applied to the ZO6 by putting screens on it.

 

My Dual Flow intake from WCC came yesterday and it looks great! The only thing I didnt care for is it came with AFE filters instead of K & N's, but I figure I can always swap them out...
