Precision V Band Inlet Turbine Housing
Talking to Precision at PRI I was told that the V band 62 trim would outflow the T4 with similar AR. Anyone have any experience with these Vband inlet/outlets? Looking at a 5862 for a fast spooling street setup.

based off the 2015 Precison catalog the turbo should make 64 pounds per minute which is just under 500 rotary rwhp.
i am concerned that the hotside being only 5.39 average sq inches might cause higher EGTs and backpressure w a rotary. as to V band or T4 it depends on your manifold... howard |
I would go by what Precision says. Rules of thumb (such as x flow rate = y hp) are just for generalizing when you do not have input from an experienced professional like the techs at Precision. I have a pretty extensive aerospace background that allows me to crunch numbers and make estimates, but since I am not a mechanic I always like to get input from those with actual experience. If theories always worked, there would be no such thing as test pilots. ;)
Stainless steel V-band clamps are excellent in high-temp conditions, can withstand a fair amount of vibration and pressure, and they are easy to work with after you weld on the flanges. The exhaust system on my turbo RX-7 has additional v-band clamps on the cat so I can quickly change it out for a test pipe, plus I could fairly quickly swap between a Y-pipe or single muffler exhaust system if I wanted to. |
