a friend told me that turbos that have anti-surge housing make less power and spools up to 500 rpms slower.. is this true.. btw he's a supra guy...also what exactly is anti-surge lol

 

Anti-Surge compressor covers help keep the compressor wheel from reversion (going in the other direction from high pressure application). Anti-surge covers are not horsepower-limiting. Your friend is not correct.

Standard GT3076R Anti-surge


Another type

 

i jus like how the ones with da drilled holes look

shodan would it hurt to put the drilled holes into the second turbo jus a question not to sound stupid and its jus for looks for why im askin

 

It can hurt if they aren't strategically placed. This is an option that Precision provides for more asthetics of their T04S compressor covers. Unfortunately, you can't just be like Homer Simpson and drill "Speed Holes" just anywhere.

 

LMAO!!

 

Googled it and this was in some supra fourm
"big hp supra guys claim they make a antisurge delete on their housing because the anti surge housing was robbing as much as 200-300 RPM spool and 50-100hp?!* all this is in reference to the turbo not surging on the set up."

The "anti surge housing" is actually called a ported shroud and its supposed to increase low end and midrange power by feeding air into the secondary fins on the compressor wheel.

"Is it true that the Anti-Surge Housing turbines don't produce as much top end hp as a "regular" turbine? I.E. a 77mm Anti-Surge housing turbine will not push as much RWHP as a 77mm without Anti-Surge? Sounds logical."

 

the ported housing robs a little power up. will it be significant? i dont think so.

 

those are are on SERIOUSLY larger inducer wheels that it MAY be an effect, and even then, it is insignificant by any means. What does that mean for you, the 2.0 litre street/track driven car? Absolutely nothing.
