Default Installed the Ultimate Racing GT35r kit with Hydra: feels absolutely amazing

It took me three days to get this kit installed as there were soo many parts that I needed to swap out, but needless to say it was definately worth it. I get 14 psi at about 3700 RPM in 5th..not too shabby, but the turbo does not get into full boil until about 4500 rpm. That's not to say that it's a slouch below that (at least above 3700 depending on the gear), but it's a big turbo (GT35r .82 A/R housing). Pulls stronger and stronger to the 7200 RPM rev limit.. In fact it pulls stronger above 6000RPM than below. Power never ends.

As a comparison, from a roll at 40 mph with a stage II STI:

Stage 2 STI pulled almost 3 cars instantly until I got into boost. By the time I was through 4th I made up the 3 car deficit and pulled 2 cars. By the end of 5th (about 140 mph... Open 5 lane highway.. no traffic), I was ..no kidding.. what appeared to be 20+ car lenghts ahead.

From a dig to 100 mph I won by about 10 car lenghts.. this was against an STI that ran a 12.7@107 MPH..

Comparison to a 2002 Z06.. BTW from a roll these are really really fast cars, as I could never keep up with my stage II.

60 mph to 140 mph roll.. (at 60mph, I'm within 400 RPM of peak boost)

Z06 pulls 2 cars instantly until about 80mph.. I even it out at about 100mph and by 140 MPH I have about 10 car lenghts. (friends Zoh with an intake and PRT exhaust that ran 12.0@116)

All of this was done on 18.5 psi.

As I said, it feels absolutely sick , almost too fast for the road.

My set up is as follows:

2005 STI (5000 miles)
1. APS dr725
2. APS Tumbler deletes
3. Ultimate Racing GT53r kit with coated piping and custom braided lines and turbo heat shield.
4. Tial 44mm wastegate
5. Dual HKS SSQV's
6. PE 850's (idle is perfect)
7. Toyota twin turbo pump
8. APS 3.5" catback (I couldn't beleive this bolted up to the 3" downpipe, but it did..., soon to be a Greddy EVO2 .. APS was waaaay too loud with this turbo.. no more backpressure or muffling from the turbo
9. Element Tuning Hydra ..good bye MAF (previously had the Street Tuner and UTEC)
10. Fujitsubo equal lenght header (getting coated right now)
11. Hydra aquamist (on the way) should be another 60 whp at the same boost level when tuned, care of Phil at Element Tuning .. can you say 475WHP at 20psi on pump.
12. Blitz sbc-id and power meter


+ lots of car stereo and other stuff.

I'll post pics tomorrow.

The only thing that I'm worried about now is popping the block. I just can't beleive that the stock block will hold up to this abuse for too long. So for now, I'm planning on running about 17.5 PSI most of the time and setting my blitz sbc-id to scramble at 22psi when needed (pump gas)

This isn't to flame,...as i can see why your so hyped on your car with the new mods,...

Its kinda hard seeing a 18.5 psi GT35r STI puttin 10 cars on a Z06 from 100-140 mph.

Keep in mind the Z06 is 2WD, has better aerodynamics...and traps 116 mph.

Congrats

Get a good race tune and some timeslips from this bad boy after you get to enjoy/drive her for a while

Sounds impressive Syoung! I've heard nothing but good things about Ultimate Racing's packages for the wrx/sti.

what's the latest on those pipes?

Default Wow...

Very nice indeed.

Although I must admit that putting the hurt on a Z06 - especially at those speeds - hmm...

I'm with everyone else here when I say let's see a time slip. But what you really should do is get video footage when you go to the track.

Do you have any (pump gas) dyno sheets to post?

sounds great man, hit the track and get us some footage.

The z06 pull sounds nuts. Im betting that your tape measure might have been off a car or too when you pulled it. Im just saying that its hard to tell once you leave someone back there. I can a pull a few cars on one of a roll, but they catch in the top end for sure. The fact that its 2WD has nothing to do with it catching. The cars put down what they put down, thats it, the car traps what it traps. If your making over 400whp, the vette will get pulled unless it puts down similar #'s. But I agree the STi is like an umbrella in the wind.

It is VERY likely to pull that much on a Z. EVERYONE forgets that it takes HP to roll those front wheels. His car (STI) is most likely 400+whp, while the Z is most likely right below that (I est 380-390whp). STI is AWHP, so that 400whp is total NET hp at all 4 wheels. When you try to get total NET hp of any 2wd car, you must subtract an amount to spin the other 2 wheels from given dyno #s. I would say there is at least a 50whp difference between the cars using this method.

He's most likely putting out 40-50 whp more than the vette, which makes what he's saying

Congrats on your new found power. I can vouch for the Z06 Hurting, because I have this kit and have walked my fair share of z06 vettes As was mentioned earlie in this post: The STI is making 30-50WHP more than the vette is, and the power band has shifted to the right a fair bit....why is it so hard to believe that he beat one? I know of a UR Stage 3 wrx that put a hurting on a z06 till 120mph

Have Fun.

Lets throw everything out the window...and look @ it this way..

400-430 whp STI (asumming its tuned),...and he put 10 CAR LENGTHS on a MODDED ZO6 from 100-140 MPH.

In a 40 mph span...with all the drawbacks a STI has vrs a ZO6 on a freeway race...

Either way this a nice setup...and i look forward to seeing this thing tuned on some race fuel runing more then the 18#'s.

I hope I'm not coming across as a asshloe.

It is definately difficult, if not impossible, to judge how much distance there is between two cars when they're moving and when the point of perspective is the car ahead. Specifically with both the Z06 and STI runs to approx 140, all I could really tell was that the Z06 was a ways behind, perhaps about 120 ft. and the STI seemed to be almost twice that.

BTW.. prior to owning the STI, I also owned a 2000 c5 hardtop with long tube headers, intake, MAF, custom tune and exhaust. Basically the z06 chassis with 30 less whp when stock with nearly identical top gear ratios. It dynoed at 360whp or pretty close to a z06 with an intake. My best run in it was a 12.4@115. I also have several friends with z06's and can tell you that the sti is noticable faster at any speed that I've dared take it. Additionally, if the Z06 is trapping 116's and I assume that the sti is trapping 122's or more, it is not at all unreasonable to put some distance between the two cars at that speed. Perhaps it wasn't 10 car lenghts, but it was definately not close.

I can tell you, from the best that I can recall, that the STI with the gt35r kit, feels noticably stronger up to 140, as I haven't taken it much past that. In fact, I never went over 115 previously as it took too long. Now getting to 140 was like getting to 100 in my stage II

Regarding the dual ssqv's, I did it for 2 reason: 1. the ssqv has a pretty small orifice for dissipating pressure and at power levels approaching/exceeding 450 whp, so I did it to increase the area provided to blow off excess pressure between shifts. and 2. it looks really cool.

Hope this helps. I'm planning on taking it to the track and dyno soon, but am trying to work out some of the tuning bugs first (getting a missfire at peak load, maybe need colder plugs?)

BTW.. stock z06's typically dyno at between 330 and 345 whp and assuming my sti dynos at between 410 and 430 whp, there's up to a 80+ whp differential and between 8-12 mph difference in 1/4 mile speeds (stock z06's trap between 112 and 115 and gt35r sti have trapped between 122 and 126 on pump).

This is a huge difference in power and trap speed.

Perhaps I should have stuck to generalities to avoid flamo . Either way you guys get the picture. The gt35r kit transforms the STI into a supercar with impressive strainght line speed capabilities. Regardsless of whether it's an Ultimate Racing, Kingpin, Godspeed, Crawford, or other kit.

I also have the UR GT35R Stage 3 package, and I will vouch for your story. I raced a z06 from 60 to 130 I beat him by at least 8+ car lengths, I was past where his headlights illuminated the ground!!! Every one I've given 'rides' to either started screaming or laughing, it really is a bargan supercar now.

p.s. I'm at high altiude so the Z06 was at a larger disadvantage in my story. I was blowing about 1.3 bar too.

Sounds good and glad you are enjoying the car. The 35R on the STI destroys Z06 vettes on the highway. Its not even a race. I guess I dont understand why people have a hard time swallowing the fact that a 400-500whp AWD STI is not a slow car.

Good luck!
