BOOSTED TUNING Custom Remote Tune - The Mile High HKS 7460 on E85
Just got done remote tuning a clients car on E85 at high elevation (5500ft). Info and charts below.
03 Evo GSR
HKS GTII 7460 Turbo
AMS LICP
CBRD 3.8" FMIC
CBRD UICP
OEM JDM/IX BOV
FIC 1100 High Z Injectors
Perrin Foam Intake with Perrin Silicon Tube, factory MAF
Works Throttle body gasket and new shaft seals
Walbro 255
AMS Fuel Line
GSC S2 Cams (new grind)
GSC Beehive Springs
AEM Tru-Time Cam Gears
Spoolinup COP
DC3 dual catch cans
JMFab Tubular exhaust manifold (DEI Wrapped)
Taipan XP Divorced WG exhaust (3" TBE) - Gutted Cat
LC1 wideband
JDM 3bar MAP sensor
GM 3 port solenoid
30psi on E-85
416hp/372tq, UNCORRECTED @ 5500ft elevation
I rarely post corrected numbers, but since the client is at 5500ft elevation, I thought it might be a good idea to post them.
482hp/431tq CORRECTED

This is my car. Previously was on a 16G TME turbo, and the HKS 7460 is about 30hp/30tq stronger than the TiAl 10.5 on 91 pisstane. Next up will be switching to SD to try and get rid of the idle stumble at clutch in and maybe gain a few horses in the process. I also plan on degreeing the cams and seeing if there can be any gains had with cam timing.
I'm curious to drive the car down to sea level and do some pulls to see the difference between uncorrected graphs. If you live at sea level please don't tell me you made more power than me on a stock IX turbo. Using data from the logs, last night was a DA of 4,734 ft (5506 asl, 39f, 24.89 inHg and 18% humidity) which is pretty awful for trying to make hp. I suppose a dump tube would help out greatly with the increased backpressure but I'm just not willing to put up with the noise. I'd love to have a compressor map for the HKS, but I'm pretty sure I'm at the outer ring running 30psi at this altitude, which is one of the big selling points for the ball bearing center cartridge given the shaft speeds I'm asking of it.

I think the real numbers lie somewhere in between the two. The next time I go on a road trip to a low elevation area I will have to do some pulls to quantify what exactly the difference is.
I don't know how Brad calculates the correction in VD...and certainly SAE correction does not discern between FI and NA cars, so there has to be some discrepancy there, though I doubt nobody will argue that cars lose hp at this altitude. I know there are lots of 1/4mi calculators that adjust for et and trap speed based on altitude and that they are very accurate. It would be interesting to compare my car at sea level vs. the VD corrected graph to see how close it really is.
One thing I do know is that altitude does not discriminate, and it really favors FI cars, which surprises a lot of mustang/camaro/corvette owners out here. I've only ever seen 3 other evos in the almost 4 years that I've lived out here. What's funny is that there are 3 R35 GTR's in town and I see them all the time.

I don't put too much faith in the corrected numbers, which is why Jay posted uncorrected and corrected; we report, you decide.

I fill up 2ea 55 gal drums in my truck whenever I drive somewhere that has e85. There are stations in abq and santa fe. This particular batch is from walsenberg, co.

I have the perrin intake and silicon tube, does anyone know of a way to keep it when going to SD? Or do I have to build a DIY pipe and ditch the perrin pipe but keep the filter...
