True Flow Air Intake System

Anybody try the True flow Air Intake? There is a good article on it here:
http://chevytruckworld.tenmagazines.com/tenarticle.asp?aid=2778&sid=1

Just wnated to see if anyone here had tried it and if so what kinda results they saw.

We noticed the Tahoe had a significant improvement in acceleration after we ran a complete set of tests on the True Flow Air Intake system, we later found that it was due to the fact that the driver’s wallet was lighter to the tune of about $250 large.

Save that money for something tangent and take your sweetie on a nice weekend get-a-way.

I've heard their filters come soaked in oil (worse than K&N or others). You're asking for trouble with fouling up your mass air sensor. If you do get one, you may want to clean and re-oil yourself (lightly).

Isn't True Flow the one that uses foam instead of cotton mesh?

lmao that's a good one. I'm gonna have to try that one on mine. Get me one of those programers, cold air intake, and a throttle body spacer which should set me back atleast 800 bucks which is gonna make my truck way fast. lol

ZX, thanks for the response. Wanted to see if anyone around had actually seen an improvement in gas mileage.

NCHEVYHEVN, no need to respond if you don't have any valid info. As you can see if you read my post, I was looking to see if anyone had noticed improved gas mileage, not looking to "make my truck way fast". I guess you did increase your post count though. Good job.

You're certainly welcome.
$250 buys a few tanks of gas and that’s a given.
GM is taking a great deal of effort and expending millions of dollars to develop and design new low restriction intake and exhaust systems, unlike a few years ago these low budget companies are going to find it next to impossible to improve upon the
performance of the factory parts, now if you like the looks or the throaty sound then go for it but don’t expect +2 mpg because it aint going to happen, I promise.

My post had valid info. Sarcasm as to not buy cold air intakes, programmers, and throttle body spacers. Your welcome.

I installed the K & N Cold air intake on my 2003 Z-71. Also did a Diabalo tune & increased the trans fluid pressure. I gained 50hp & 30lbs TQ at the rear wheels. My gas mileage went up 12-15% even with 10% ethenol in the fuel. I pull a car trailer & the difference is very noticable.

So I assume you did a dyno run then right? Numbers sure do sound pretty even. You sure it wasn't your ass dyno?

Yes it was Dyno'd 3 times once before & two after by http://www.aca-performance.com/ I Also installed air lift bags in the rear springs because Tahoe springs can't support anything bigger than an occasional xtra butt. I was quite supraised to by the numbers, but these engines can make lots of hp & tq fairly easy. I am running 295 RWHP & 340 LBRWTQ . By the way I pull a 68 vet with 500HP & 600TQ on a tilt trailer.

Sorry but until you post up your actual dyno runs then I don't beleive you on picking up 50hp with a cold air intake and a tune.

Also your link doesn't work.

I fixed the link. instead of me wasting my time with you . Why don't you e-mail ASA and ask them abouts Alan's Tahoe on the dyno, that way you'll hear it from 2 people or you can come on over & pay for the dyno & see for yourself. That's my Blue 68 vet on the page & my mopar 392 stroker motor also in projects. I would suggest in the future before you question someone to get all your ducks in a row.

Link still doesn't work.

I don't see how your waisting your time. You come on to a forum claiming to have certain horsepower numbers. Anybody is going to ask how you get the numbers. I guess maybe you expected a "Wow that's super cool" or me to just automaticly beleive you. It's not a big deal. If you don't have proof of what you say then just say I don't have any dyno sheets. I'm still not going to beleive you because their are just too many liers on the internet claiming false numbers. Sorry.

That's like me coming on here saying I run 8s in the 1/4 mile. Don't you think someone is going to ask to see some proof.

And I'm not going to waist my time by going and calling people cause pretty much you ended the coversation by not proving anything which means your didn't make 50hp with a cold air intake and a tune. You lose.

I, as a potential purchaser of a product that makes such claims, would want to see proof of such fantastic claims before putting down my hard-earned bux...

I'm with you heaven.

I've read a few remarks by member NCHEVYHEVNand this guy is a JERK.

I run a Corvette C3 forum (about the size of this forum) and he would have been banned from there by now.
This Chevy forum has: 3158 Registered users have made 6225 posts. There are currently 2443 topics.
My Corvette forum has: 2759 Registered users that have made 62994 posts. There are currently 8545 topics there.

Alan, (knotacare) is one of the better members I have and is very straighforward and honest. Calling knotacare a liar to his face makes NCHEVYHEVN a first rate JERK and Ahole!

I suspect this will be deleted in time, but I had to say my bit.

Not to butt-in on your post davemec, but Jacks77 is right. NCHEVYHEVN is a jerk, if you look at some of the other post on this site, he is telling most of us we are wrong and stupid. I also think he has a big head, and I personally don't really pay attention to what he says. However I will say that for EscalonJon I do see your point. But no one is trying to sell anything on this post and the link does work. To add on a newer car it shouldn't be hard to get 50 hp with a tuner. You just have to have some idea of what you are doing.

davemec as for your question, I can only answer that so well as I don't have a Tahoe, but any intake should help with power, you will have to do some checking or asking to see if it will help with mileage. Tuners are not a bad way to go either, if programed right you should have more power and better gas mileage. (it wouldn't hurt to stay away from a filter that has oil on it either).

Thanks for the response guys & you're absolutely correct to make 50 xtra HP in these cars is not hard in fact with some new pistons & head work 500+ HP is what they do at ACA quite offen. But that 50 xtra hp & 30 TQ at the rear wheels makes a big difference when you're pulling 5K. It's ashame there's people like nchevhevn & I doubt he even owns a Tahoe or knows how to open a hood. I've probably wrenched on cars longer than he has been alive & owned more than he has ever driven. He must like to sit in front of his computer alot as much as he has posted here. I actually came to this forum seeking info on trailer wiring and got the info in a few days which I was very thankful for. I will check back from time to time & if I can answer someones question I will.

knotacare
I am pretty sure he dosen't own a Tahoe, if he does it's not a new one. But I do know he works at a dealership, I think that has givin him a big head. But I agree with you, if done right you can get a lot of power out of the newer cars with a tuner alone.
But that's just my thought.

Boo hoo.

I don't have a big head and I'm not a jerk. The guy posted up some numbers, I asked how he got those numbers, he said dyno runs, I didnt' beleive him so I waved my BS flag until I saw some dyno sheets. Sorry but I don't beleive him and it's pretty common on other forums for people to ask to some proof because incase you didn't know their are people on the internet that lie and don't know what they are talking about. 50hp to the wheels with a tune and cold air intake. Nope, sorry I don't beleive him until I see some proof. If he shows me some proof than I will retract all former posts and eat my own words.

As far as the other members who don't like me o well. I could careless. I come hear to help others which I do. And anyone who gives bad advise I will call out just like I would be expected to be called out if I gave bad advise. I don't think anyone wants to be given bad advise.

As far as me calling others stupid I may have but come on I've heard some pretty bogus advise. In one of the malibu threads I saw another member say that the reason a guys brakes were squeeling was because the rear coil springs were broke. I couldn't help myself but to call that guy out. If you honestly have no clue as to what your talking about then simply don't post is how I see it.

Nope I don't own a tahoe and I don't have to know what makes real power and what doesn't. Research is all it takes which I do pretty much everytime I'm on the computer. I'm constantly researching to see how things work, what's the best bang for the buck, and etc. I go looking at manufacturers websites either because they throw out some power numbers that arn't true either. I go and see what consumers have to say and what the facts say.

Also on getting big power out of a tuner is bull also. Sorry but I'm not sure how it all got started as to why people think you can just program tons of power is crazy. It's all marketing. Most of the tuners out are crap and not even worth the money. Most are only good for is changing tire size, raising the speed limiter, and at best tightening up the shift points but most their not even needed. Custom tunes are the way to go but even those aren't going to net you big power gains. Now no I havn't done either but I have researched to see what works best. No I didn't just hear that from one person like I see others do. I have reseached and found this to be true from multiple people across the net.

Yes, I do work in a dealership as an intern only while I finish getting my degree. Does that make me a big head. I guess to some it does.

O well you either like me or don't like me but I do help on this forum and I do correct people when their wrong just like I would like to be corrected when I'm wrong. No shame in being wrong. I'll be the first to say when I'm wrong.

Well, your response proves what I said... your a JERK and most people here don't like you!

If you don't own a Tahoe, why in the heck are you even posting? Oh yeah, to prove how dumb you are.

Like I said just because I don't own a tahoe doesn't mean I don't know how they operate and what makes power and what doesn't. Research is all it takes.

Research is kinda like going to school and only doing book work to learn how to work on cars, yeah it helps but you still don't really learn untill you start to actually work on a car.
Thus not owning one research only goes so far.

I don’t want to get into a pissing contest with anyone about which performance parts work or don’t work or how much power you gain with this or that.
With that said I’ll post my opinions (for what they’re worth) that I have gained over the past 13 years working with GM.

When testing various components and designs in the modern Vortec engines that are geared at improving the engines volumetric efficiency (ability to breathe in and out) we have almost reached an impasse, what we are finding now days is that many so called performance parts simply move the power up or down the RPM scale, we recently tested a performance “free flow exhaust” system that had a claimed 22 HP/25ft lbs increase, what we found was that at lower RPM’s the power and torque figures were actually reduced fairly substantially but as the engine was rev’d over 4,000 RPM the power came back peaking at 5,600 RPM’s with a 6 hp gain but 9ft lb loss. When we took the vehicle out for a test drive the seat-of-the-pants feeling was that the vehicle seamed faster when in fact it was slightly slower but as the power band came alive the acceleration became more noticeable giving the impression of a nice power increase.

My point being simply that most companies that produce performance parts for the new Vortec engines do not have the capitol or resources to R&D their parts properly and while they may increase power at various RPM’s it normally comes at a loss in power at other RPM’s.
One other thing to keep in mind is that the Vortec engines have one of the least restrictive intake manifold and head design of any modern V8 engine but they still take very well to a good old fashioned port and polish job which simply improves the engines ability to breathe, this should be one of the first course of actions for anyone attempting to gain any real power without utilizing forced induction.
