Precision making more power then garrett well that is not turbo based. It’s because precision does this on purpose. If they sell you a .48 a/r it’s really closer to . 50-.52 and hence why they can make more power…it’s all volume based…while with garrett you get what you pay for unless you specify and they custom make you a turbo! (if you are a distributor) > > lastly a 50 trim: well no duh you won’t make serious power on it until it reaches about 22psi or so depending on displacement!!! If you ever look at a comp. map of that turbo you will understand that it doesn’ t get into full efficiency until those higher RPM numbers! 25.5psi on a t3t4 50 trim on a GTI made 419whp! > > [http://forums.vwvortex.com/zerothread?id=1213280](http://forums.vwvortex.com/zerothread?id=1213280) > > lastly there are companies like ITS that make nice housings, and use only 360 thrust bearings on most of their turbos! But, you have to remember the only way to get a great deal on a great product is to buy direct IMHO!!! LOL precision uses garret stuff and I never said they were better than garret I just said they are close in performance, specs, and reliablity ---

Blah blah blah… dig up all the facts you want. I made 470 rwhp on 24 psi with a gt30r. It spooled extremely fast and still had crazy top end. Trapping at 129.90mph on a botched run. My motor is very similar to that of the 4g63. I think the gt30r is the perfect match to any 2.0 liter. ---

Or just figure out what turbo best fits your needs. Its really not very hard to do the math and figure out what fits your goals. It might take someone a whole 5 minutes to figure everything out so you can read a compressor map and see what works. ---

> [@kilmer420](#): > > usually turbos surge/comp surge due to comp. housings being too small :huh: I didn’t think that was the case. Why is there a diffuser in bigger turbo’s then? Like 1320’s turbo. These are originally applyed to big truck turbo’s (which make there way onto imports). Since the turbo is so big and on a big truck, will constantly run at its maximum pressure, a diffuser is used in the intake side of the compressor to “fool” the turbo into thinking it isn’t surging. Surging usually occurs at full boost in the lower rpm’s when the engine isn’t producing enough efficiency to swallow the huge charge of air the compressor is now making at spool-up. The diffuser allows the air incoming to “diffuse” around the intake port to allow the turbo to what some people call burp off the surge until things get cooking again. You hear big HP, big turbo supra’s do it all the time. Please feel free to correct me if I am wrong. I am all about the learning process :blue: ---

this thread sucks. Stroker cant handle/afford/ever build a 500hp motor for his DSM. Get a 20g, make your 350-400hp and be happy. ---

I am all about the learning process :blue: i was under the impression the definition of compressor surrge was the throttle plate closing when the compressor was still spinning and the air backs up into the compressor housing and has no where to go but back through the blades, that causes them to try and spin backwards but they can’t so the blades usually bend tat that point. (since that’s the definition i got online) diesels dont’ have throttle plates ---
