Forge Recirc Valve vs Subaru OE Recirc Valve Dyno Test by Pure Tuning.
We still get Subaru WRX / STI owners today that say “the original equipment turbo recirc valve is adequate for any turbo or boost level so why should I change it”. What a better way to prove if this was true or not then on a stock car.
For this test the valve in question is the Forge Motorsport Recirc valve that sells for around $170. This is a direct bolt on replacement valve that uses the adapter from the OE valve to recirculate the exhaled air back to the induction hose.
The car tested was a bone stock 06 STI with mid 20k on the odometer. Looking at the dynograph you can see the difference in power before peak boost is reached at 3800rpm. The OE valve hangs open a little which is primarily for smooth transition between shifts so where this is great for Granny it’s not what we are after. The Forge valve shuts immediately giving the engine all the boost and air volume as the turbo is providing it. The peak number didn’t change as the target boost is the same but the increase in boost pressure below 3800rpm netted 10whp at 3270rpm and 17ft/lbs at 3300rpm.
That is defiantly usable everyday performance!

These tests were performed last quarter 2006. I have been meaning to post a few of our tests on our blog and I’m now just getting around to it.
Car: Mitsubishi Evolution IX MR with 1500miles on Odometer.
Parts testing will be progressive with parts being bolted on taking convenience in mind.
Parts are bolted on without tuning unless specified. When we conducted these tests we tried to take it from the consumers view which was to bolt on the parts and eventually get them all tuned in.
Test are performed on our Mustang Dynamometer MD-1100-AWD-SE

The spy shots from PRI show the new Tial Sport 44mm MV-R wastegate to replace the old V44 scheduled for release sometime in the first quarter of 2010. This new MV-R wastegate is not just smaller and lighter than the older unit but it also has the option for water cooling. There is also no need for re-plumbing as the new MV-R is a direct bolt on replacement for any V44. Trust Pure Tuning to have some available as soon as they are released.
Also included a picture of Tial Sport’s new recirc blow-off-valve scheduled to be released soon.

Autobahn Country Club was a great venue for this event as the track and facilities are top notch, but over the years the south course has gotten a little bumpy making it a little more challenging.
The car was great and fairly maintenance free all weekend. The tracks bumpy braking zones made it challenging for suspension dial in but after a couple sessions we were able to dial the car in where we felt there wasn’t a loss in handling ability.
