Forced Performance FP RED Turbo Subaru WRX/STI. This turbo can be special ordered with a dry bearing housing that allows you to eliminate the water connections to the turbo. (Please call for more information). The standard configuration uses a Subaru type water cooled bearing housing with both water connections on the same side of the CHRA. The thread specifications for the wet housing are as follows: Oil inlet - 10mm x 1.5mm, Water in/out 14mm x 1.5 (same side).

FROM PDX who recently tuned this turbo: As most of you have seen from the previous thread (http://forums.nasioc.com/forums/showthread.php?t=849824) we have been pushing the 8cm Forced Performance Red on one of the PDXTuning STIs. We took the car over to the local Dynapak dyno for some more tuning. Our goal was to push the midrange boost a bit more, and refine some of the fueling. We target getting a bit over 30psi in the midrange, as well as having it hold to 30psi at redline. We set the boost controller (AVCR) to 90% duty cycle the entire run (learn and feedback off), so this is about the max of what the internal wastegate combo will run. The results: 510 lb-ft of torque at 4900 rpm, and 521hp at 6700 rpm. These runs were done on the Dynapak, which as you can see below, records a LOT more torque compared to the Matrix Mustang Dyno. It is well established that this dyno design (which hold the car at the start RPM for a configurable time, often 2-4 seconds) can results in higher then normal torque. (at least when compared to a regular inertial dyno). Also, the load pushed against the car is linear in nature, as the dyno tries to control the ramp time to a liner and constrained rate. (you set the time for a pull). On the other hand, the Mustang simulates real world load by adding additional drag at higher RPM to simulate aero drag. To be clear, in no way would this same car make 510 lb-ft on the Mustang dyno. This should be yet another clear demonstration that you can't make comparisons across different kinds of dynos (much less even the same kind). Here is the plot of what the car did. ( Note that this is with SAE corrections, which are what most shops use. The dyno can also show either uncorrected or DIN correction. The correction factor wasn?t much, since the SAE standard is at 77 degrees, and it was about 80 on the dyno. ) I have not yet seen a shop post results with DIN correction (which reads lower). As per the previous thread, this is with C-16 fuel, AFRs in the 12.0-12.5 range, and timing was as per the previous thread as well (ramping to as much as 31 at redline). Also, on the previous thread it was mentioned about the possibility of this car doing a 10 second 1/4mile. While we have not raced the car yet, I would suspect we could get something in the low 11s, but I would not comment or promise it having the power to do mid to high 10 seconds. Based on what I have seen from our results on the mustang dyno, something in the 380-400whp range usually nets 118-119 mph trap speeds, and perhaps 11.9-1.7 ETs. ET's are very dependent on the launch, while trap speed is more power dependent. You would suspect that 500 whp on the Mustang dyno would net something in the 125mph range. As for the ETs, it would be very dependant on the launch and the shifting.

DeatschWerks injectors come with a rebate coupon. When you send back your stock side feed cores they give you $160 back! Also, the top feed injector cores will get you $100 back!

This turbo is only available in a 3" Compressor Cover with 8cm turbine housing. Standard wastegate configuration will now be for an External Wastegate, adding an internal wastegate is now a $150.00 option.
