Default 06STI-Perrin GT30R-480whp (PDXTuning)

Here are some results of tuning a customerís 06 STI with the Perrin GT30 turbo kit. This kit is based around the 52lb/min GT30 turbocharger with the .82 A/R turbine housing. You can optionally get the .63 A/R turbine, which offers slightly quicker spool and a bit less top end.

This car has the usual supporting mods: Perrin FMIC, BigMaf, Perrin 816cc Injectors, Perrin GT30 turbokit, ported TGVs, fuel pump, gauges, as well as fresh Mahle Forged and Coated Pistons. It is also using the most excellent TurboXS Electronic Boost controller, which is a serious joy to use.

This car also has a complete 2D+DDS3 Aquamist water injection system, but we are planning on tuning the WI setup with a 50/50 water/meth mix next week. This tuning session was meant to generate a base line pump and race fuel map with no water injection.

Engine management was a Cobb Accessport with a PDXTuning Protune map, plus a TurboXS UTEC. Tim protuned the Accessport first, starting at 14psi and working up to 21-22psi. Peak power with 21-22psi was 411whp on 92 octane pump fuel.

We then switched to the UTEC so Mick could make a starting pump fuel map. At the same boost level, with a little more refinement of the fueling, Mick was able to get 415whp. Power and torque were about identical with the Accessport and the UTEC. The combo of the Accessport and the UTEC, much like the EcuTek+UTEC, allows the best of both worlds. Launch Control and Flatfoot shifting, plus excellent drivability, anti-theft, upgradeable maps, check engine light fixes, etc.

Letís take a look at the dyno graphs:

On pump 92 octane with no water injection, the car made 411whp and 389 lb-ft of torque. This was with 21-22psi of boost, and typical 92 octane AFRs of 11.1-11.4.





We then added 5 gallons of C16. With just a quick run with a bit more timing and leaner AFRs, the car made 423whp and 396 lb-ft of torque. This was at the same boost pressure as before, and the additional power came only from the change in combustion of the C16, and the resulting later timing needed to maintain power. I suspect that if you stayed at this boost level, another 10-20whp could be extracted if needed.




Next we turned up the boost a bit, leaned out the AFRs, and added a bit of timing. With 12.1-12.5 AFRs and 24-25psi of boost, we netted 455whp and 448 lb-ft of torque. While boost would hold at 24psi, it was nearly 100 duty cycle at redline.




As we turned up the boost more to 27-28psi, the boost would hit 27-28 in the midrange, but would fall to 24 at redline. At this boost level, we netted 480whp and 473 lb-ft of torque. At this power level, the Perrin BigMAF was at 4.9-5.0V, and the Perrin injectors were at 90% duty cycle (thanks to the lean burning C16).




It is interesting to look at the 22, 25, and 28psi graphs together. You can see how the jump from 22-25 netted the most, and the additional 3 psi to 28 netted less. Clearly the 52lb capacity of the turbo is the high end limiter.




Here is a look at the datalog of the C16 pull, showing AFRs, Timing, and Boost.



400whp on pump fuel with great drivability is just awesome. This turbo kit delivers very well. We also tuned another customer car that had an APS SR55, so I plotted the pump gas comparison below. The SR55 ran well, but had WORSE spoolup and low end torque then the GT30R, and the 30R was with a .82 housing! As you can see from the graph, the APS made about 360whp compared to 411 on the Perrin GT30. The APS made the most power at about 22psi, but the difference in power from 18-22 was not that significant. Given the price of the APS turbo, I just donít see it delivering compared to a real Garrett designed housing.




The combination of the FMIC, Injectors, and the turbo kit made for a great setup for both street and track! This setup on pump fuel is incredible.. Gobs of power, and more to come with the water injection.

The addition of the forged Mahl pistons is a key to keeping the car reliable over the long haul. The Mahl pistons are much quieter then the CPs, partially because of the wall clearance, and partly because of the extensive coatings on the Mahl pistons.

Keep in mind this the the 52lb GT30R, not the 65lb/min -14, or the GT35R. Needless to say, the Garrett engineering housing do very with, almost like they were engineered by a turbocharger company.

Also, note these are wheel hp measurements, not an inaccurate unscientific and unjustified attempt to correct to theoretical crank hp.

Cheers,

Jeff Sponaugle

This was done at Torquefreaks, since Matrix was unavailable. They have a dynojet (as obvious by the graphs). The most amazing difference is the way torque is measured (actually indirectly of course). The dynojet reads torque much higher at lower rpm then the Matrix mustang, and a bit less high and fast then the Dynapak.

Jeff, what does a stock STI put down on this Dynojet? Any thoughts on what it would have put down on Matrix's old dyno? What do you think the difference between the .63 and the .82 are?

I have a dyno here you can use.

I have a dyno here you can use.
I will have to dig around and find out, since this conversion to 4wd was just recently. I haven't had a chance to put a good comparible car from the Mustang dyno on yet, but the biggest difference seems to be in the midrange torque. The dynojet reads higher and at lower rpm. The mustang we tuned on always read the lower end torque very very low. The actual peak hp numbers don't seem that different, but a real direct comparison will be the best way to compare.

We will be tuning a nearly identical setup with the .63 housing in a few weeks, so we can get some good comparitive data.

Cheers,

Jeff

I have not tuned the GT35R on this dyno with a regular STI, but with the 35R Perrin kit on my car (JDM Spec C heads and 2.5L block) I was in the 420-430whp range on pump gas. I would suspect on C16 there would be more relative gains, and on the Mustang I was able to get 480whp, so I would suspect over 500whp on this dyno.

hey jeff,

do your modified injectors always flow at 816cc, because i recently bought some injectors that claimed to be modified by you guys, but i had them flow tested and the flow a bit higher than that - 832cc to be exact...

they run great though! haha.. wish i had a bigger fuel tank!

Very, very nice. Just curious. Why Cobb AP + UTEC. I could understand ECUTEK + CObb or UTEC, but AP + UTEC seems redundant.
Congrats on the tune and to the owner.

I have seen different measurements from a few different places. RC usually reports 816-820. One of the local shops here reports more like 830ccs, and I have seen several other reports in the 820-830 range. I suspect it is a variance in the length of the test, the test pressure, and the test apparatus.

Looks like you getting almost full boost at like 3500rpms?

No....look at the graph with the AFR's, boost and timing.

Full boost is at 42-4500 rpm cant really tell off the net.

At least for the 24 psi run (i guess all the plots would plateau like that with the map sensor limitation).

And If I'm not mistaken the peak boost is almost always where the torque curve starts to roll over or plateau, which is also 42-4500 rpm on all the different tunes. That way if you dont have a boost plot you can see where its hitting full boost.

If i'm reading it right it looks to be at about 10 psi at 3500 rpm.
