I have a Holley 58mm Throttle Body on my car but now my Intake elbow won't fit over it. Any suggestions?

 

yeah it will, it is a really tight fit but I ran a 58 bbk on the stock elbow. take the maf off and put your hand inside the elbow to get it on the bottom. You may need to use some lube the first few times.

 

I'm a '93 so now MAF
should I just buy an 1LE or vortech or trickflow

 

Never used a Vortech or trickflow, but why fix it if it's not broken. The 1-LE elbo is a really good design. unless you can save money. I would stick with the 1-LE.

 

The 1LE elbow is much easier to put on. A little silicone grease or vaseline will make it slide on easier. I had no problem with the 1LE on my stock TB. I tore the stock elbow because of the silencer making it harder to install properly. The price through GM parts direct is about the best available for a 1LE Elbow. It also comes with a new IAT sensor. At least mine did.

 

What is wrong with the Vortech elbow? My friend has one and it is a nice piece.

 

Ther's an issue with the steel elbows retaining heat and possibly heating up the intake air. I really don't know of the true effect they have. I got the 1LE for good price and it works fine.

 

my opinion, ur just paying for looks if thats what u like to do....other than that 1LE

 

I doubt that the air charge flowing through the elbow is going to get that much hotter considering that the intake manifold itself stays pretty warm.
Besides, it's not like the air is just sitting in the elbow waiting to get sucked it.

 

That's probably true. I was just conveying what I have read in other threads. I have the SLP intake and it get's pretty warm but considering the speed of air movement through it, it probably doesn't affect it. I guess what it gets down to is price verses looks and functionality. The 1LE performs as well as any of the more expensive ones. That's JMHO.

 

Although the air may heat up the sensor in warmed up metal elbow may actually be reading too high since its heatin up the resistor in the sensor a bit more than it should. This would happen mostly in traffic i guess...

Also if the !TB mod can cause a gain of an hp or 2 on the dyno, im sure a thin metal elbow sitting right behind the radiator, connected to the TB and on top of the waterpump would soak a fair chunk of heat. Just how much of an effect that has nobodys really ever tried to figure out, but i'm sure it's more than a rubber elbow .

 

Aluminum is an extremely effective heat sink due to it's efficient transfer of energy.

Rubber is not.

Air sucked in to the intake (espescally with a CAI) is much colder then the temberature in your engine compartment.

Why is that REALLY bad.
The Greater difference in temperature. The more effective and quicker the heat transfer.
That means that the more efficient your CAI is. the more your metal elbo is hurting you.

I have the same TB. It was a bi** to get that intake elbow on it. And every time i change the thermostat for winter/summer, its still a PITA. I just leave the stock thermostat in now.

I find that a butterknife is useful, you can slide the rubber over the knife easier than you can slide it over the throttle body, then you slip out the knife while the rubber on over the top of the TB.

This would be the last step, after geting the elbow around the bottom and sides of the TB first. A helper is nice to have, and be careful not to damage your rubber elbow with the knife.

good luck

 

Isnt that the truth.
