Element GT65 bolt-on, Hydra, Hydramist, 494 whp

Element Tuning · 07-16-2009, 04:24 PM

This WRX turned out great for a track car! We could only turn up the GT65 bolt-on to 25 psi before fuel pressure started to drop off. This car has been sitting for about a year and the old 110 oct wasn't so fresh but the 100 octane was.

Since this is a road race car the tune is conservative but still impressive for only 25 psi. On this dyno rotated 35R cars without head work only hit 490-500 at 30 psi (dyno reads about 7% low in my experience for whatever reason).

Mods:

Element Tuning Motor (25 STi block with OEM JDM heads)
Element Tuning GT65 Bolt On Turbocharger
Element Tuning 3" Silicon Inlet Hose
Element Tuning Competition Catch Can
Element Tuning Hydra EMS 2.5
Element Tuning Hydramist
FMIC brand?
3" Exhaust brand?
1000cc low impedance fuel injectors
Walboro fuel pump (too small to exceed 25 psi of boost pressure)
Andrewrtech built PPG 5 Speed Dog Box
Sunoco 110 and 100 oct fuel

I would have loved to been able to put a good fuel pump in this and turn up the Element GT65 bolt-on to 30 psi to see what it could do. I think it would have gained another 35-45 whp more with +4 psi of boost but it has a new home in Europe now.

Thanks,
Phil

Wow, 143 views and no comments? 494 whp on a stock-position turbo is no slouch! Great numbers, Phil! I can't wait to get this turbo on my STI

Sounds like a really great car. Have any plans to bump that psi on it?

jigga · 07-17-2009, 12:30 PM

what does a stock STi make on said dyno?

Element Tuning · 07-17-2009, 02:35 PM

Thanks.

I don't tune any stock Sti's LOL! 290 whp (closest I've done to stock) ran 110 mph, 500 whp and customer's trap 130 mph, 540 whp and they trap 134 mph, and 600 whp runs 140 mph trap for what it's worth. My 08 WRX dynoed 185 HP if that helps.

This car is getting exported but I wish I could have changed the fuel pump and bumped it up to 30 psi. When things slow down with racing I may run one on my car at 30 psi.

Thanks,
Phil

Nice peak numbers. Power drops off like crazy pass 7k rpm, would you really rev it to 7.5k? Also, what JDM heads are being used?

D Money · 07-17-2009, 03:17 PM

Awesome numbers Phil! How do you think the PPG's will hold up with that kind of power?

Yeah the car doesn't have any cams or headwork. I think these are just like OEM USDM STi (not big port) heads but shipped from Japan

(not all JDM is better).

It's best to shift by 7500 rpm on this engine which is similar to what you find with the USDM STi using stock heads and a 35R. Running to 8k rpm is really only useful in 1-2nd gear.

The PPG Straight Cut gears on the 5 speed are reliable up to 550 whp from my experience. I used to run this box on my WRX Time Attack car up to that power level and that car was trapping 134 mph in the 1/4 mile. It may be able to handle more but I never pushed it past that.

syoung0298 · 07-18-2009, 12:55 PM

Congrats Phil. I am looking forward to having you complete my build.

FunkDoctorSpock · 07-18-2009, 12:56 PM

that is a sick setup! congrats

That was on your black bugeye back in the day, correct? I was just wondering because I have the PPG box and was scared my power level will break them.

Yes exactly. That car was sold and unfortunately stolen and stripped. We went through a lot together. LOL!

EGY5 · 07-19-2009, 12:32 PM

I love seeing these plots (and the ones on your site).

Makes me too excited to add meth to my GT52, but I promised myself pistons first

Thanks. You can still add meth to your Element GT52 with stock pistons. Add the meth, turn the boost up 3-4 psi but only add 2-3 degrees of igntion timing and it will be fine. Just don't let it detonate at all with the stock pistons. As long as you're not greedy with the ignition timing they can be very reliable.

Thanks,
Phil

Very nice but for gods sake put some dam smoothing on that thing!

*03wRx* · 08-10-2009, 11:11 PM

wow very impressive. I am in a bind trying to figure out what turbo i want to run with my new build... have it between atp 35, dom 4, element gt52 or gt65.... decisions decisions.

you should be. I broke mine @ 365whp. Mine was a syncro set not a dogbox but still

This car was built a couple of years ago and it was plenty for the GT52 at the power level the original customer wanted. The Walboro was inadequate for the GT65 and I agree for most of the cars we build at Element Tuning we use a Bosch 044 and sometimes an A1000 on setups using a our surge tank kit.

Thanks,
Phil Grabow

Any links to said surge tank kit? I checked the website.

spoolinsti05 · 08-25-2009, 09:01 PM

Nice work Phil. I bet this customer is very happy

Element Tuning · 08-27-2009, 03:56 PM

Thanks yes the customer is very happy.

We now make the mounting plate one piece. Some have asked why the plate is so large. We do that so you have lots of options to mount the fuel pump, wiring, and a Hydramist (water/meth injection pump) if you want. Also the gas tank is very close and it's easier to mount using this type of design as you have two existing seat bolts and then the rear of the plate is behind the gas tank so there's an easy and safe plate to drill two mounting holes. The can is also mounted in the safest possible place between the strut towers and in front of the rear frame rail.
