Is anyone here familiar with clipping a turbo? I need to know how to go abouts doing this. Thanks

 

Clipping the wheels is horrible! It kills efficiency! Don't do it!

 

When you say effeciency, what are you referring to?

 

Turbine Efficiency : The ratio of the useful energy to the energy supplied to it as delivered by a dynamic system which converts kinetic and thermodynamic energy into mechanical power by means of blades arranged about the circumference of a wheel.

That is the formal definition

Increased turbine efficiency gives better boost response and higher volumetric efficiency.

Go pick up Sport Compact Car volume 14, No.67 July 2002, has awesome turbo performance dictionary as well as all types of other great info regarding turbo selection.

The only reason I ask this is because first of all, I already have everything hooked up and running. Secondly, I know that a lot of the DSM guys do this to get power up top. My problem is that the turbo spools quickly but maxes out at around 5500 - 6000 rpm. From my understanding, clipping the turbo will take more exhaust pressure to spool the turbo and the boost will not come until later on in the rpm range and this is what I think I need.

 

Clipping does exactly what it sounds like. They take surface area off the fins to increase the flow potential of the turbine wheel, BUT it spools later. The actual size of the housing isn't increased, which woul dbe the thing I'd do before clipping a turbo.

If you've got a Garrett like 75% of us on here do, then you've got almost an infinite number of options without clipping, or buying a new turbo. Contact a turbo professional at someplace like Dallas Turbo, or Texas Turbo, or turbonetics and they can help you purchase the right housing and wheel <if you need a new wheel> for about the same cost as having the turbo clipped and balanced.

Just my $.02.

 

Thanks man, my turbo is a t3 off of a merkur so I'm pretty sure there are a lot of options as well, I just don't know what is needed however. If I were to simply replace the compressor side, would I have to replace the housing as well as the compressor wheel? how does this exactly work? I keep the t3 exhaust turbine and housing? How much do these normally sell for? Any input would be greatly aprreciated. thanks

 

Just get a new turbo. Clipping the blades is gay....

 

I'm sure a lot of dsm guys (and others) would disagree with you. Maybe not on this forum, but in case you didn't grasp my initial notion, I'm trying to see what I can do with this specific turbo. Thanks for the input however.
