which TBS should I get
 

I went to summit and they have two transdapt TBS for my 4.3 a sooth bore and a swirled bore. Which do you think I should get and why. I couldn't find a real difference other than they said the smooth bore one doesn't whistle.

RE: which TBS should I get
 

It's all based on if you want that whistle sound or not. My Jet Performance is slightly swirled, but there is no whistle at all. I think Airaid is the loudest.

look man i have seen the dyno differences ..as i have posted a few months ago...but the smooth bore is the best performer of the bunch. just think straight flow or a swirl?? the swirl was actually proven to slow velocity down. i mean i love the swirl, and there is such a small difference it would not matter which one you get. i like both and think either is a great decision.

RE: which TBS should I get
 

They say the swirls help the air get around the bends in the intake manifold.

the way they are made im sure they do. i just remember when i was dynoing my 03, i had a smooth bore given to me by a friend, and a Airaid swirled, and the airaid had like almost 2 hp and 2 ft lbs less. not like that would ever be noticeable, but for a minor bolt on it showed the difference.

I don't have a spacer on mine, but I still seem to have a whistle. It almost sounds like I have a turbo and you can only hear it when I getting higher in the RPM's. I know hunt4game has heard it. Does anyone know what could cause that?

superdd - are you sure there is no air leak? That will give you a whistle.

RE: which TBS should I get
 

Is there any easy way to find an air leak? I've never worked on one before so I don't really know what I'm looking for.

i know an old trick my dad used back in the day, and that was spray carb cleaner all over your intake tubing, if it picks up on the idle, you have a leak, if you hear no change in tone, you are good.

RE: which TBS should I get
 

I've heard that old trick too. Check are you seals and clamps. Make sure your clamps are fasten down well. If you have a leak, what better excuse to get a CAI!!

Will the Carb Cleaner melt my tubing? I've seen some nasty stuff happen in the past with plastic and carb cleaner.....
Thanks for tips - I'll try it this weekend.

RE: which TBS should I get
 

Unfortunately this may not help you. It only works on carbs since you are spraying past where the fuel comes in, so it burns off as fuel. For air only leaks you will have to just look real well, then put electrical tape over any areas of concern and see if you still have a leak.

Are the TBS's actually worth the money? I already have a K&N CAI kit installed and my MAF is descreened, will the intake kit still fit with the spacer?

RE: which TBS should I get
 

Yes, the TBS's are certainly worth the money. Increased throttle response is the thing I noticed the most. I really didn't notice a difference in acceleration, in conjuction with the CAI it is a great addition. Do you have electric fans? If you don't, your CAI will not fit when you install the TBS. Unless, you shroud some of your fan guard. I purchased the Granatelli CAI and I had to modify the end of the CAI and cut a block section out of the fan guard. I know on performancenter.com, K&N states that there CAI's will not work with a TBS. It's a pain in the ass, but there are ways around. Let me know if I can help you any further.

RE: which TBS should I get
 

No I dont have electric fans although I am considering buying some.. Does anybody know which fans work the best for the least $$$? Keep in mind I go out to the HOT California desert a lot...

RE: which TBS should I get
 

If you are buying new fans, specifically for your truck, unfortunately it will not be cheap. On performancecenter.com, which has some of the best prices on the web, you will not find an electric fan set up for under 400 dollars. I'm looking for a wrecked Silverado in a junkyard, so I can take the fans that route. Also, there are other fans that you can buy and make a set up for them to fit however, I'm still researching to find what's best.

RE: which TBS should I get
 

Did you guys ever find a way to get the cheapest good fans and make them work on our trucks? If I look at a junk yard what do I need to look for? A newer 05 because they didnt have them in the 99-02 right? Anyways, let me know what you have found, my TBS should get here saturday and am worried about it hitting the fan blades. How did you get yours to fit. I dont know how I am going to trim the intake the tube because the way the k&n are the clamp is pretty much to the end.
