If you run the turbo within it's designed power and rpm, it doesn't need a gate. Our problem is we like to overspeed turbos for racing, and a gate could potentially save the charger from our abuse.
When I first tested the High Tech, I left the gate alone, and it made about 30 PSI. Then I cranked the gate down, and it hit 34 PSI. In the process it made ~35 rwhp more. Then I shut it down completely and hit 40 PSI and picked up another ~40 rwhp. But, the EGT's went way up, and the charger was running off the top of it's map. Which will kill it eventually.
The ungated GT4088R made nearly the same power as the HTT with the gate forced shut.
So the question is, if you have a gate, will you be content to leave power on the table, or would you crank it down? What happens is, most guys will crank it down anyhow.
