Tuning done...My NA RS redlines at 8,000 rpm!

dcoty · 04-29-2003, 02:53 PM

No more waiting!

I got back form lachute yesterday to complete the tuning on the new motor. It was a bit fo work to tune it and we did have fuel issues as well.

The first thing we did when I got there was do some quick number changes on the lower powerband, then we changed the rev limit to 8,000rpm and took it for a spin.

The car sounded amazing that high (around 7,000 rpm) but I had to stop b/c we were running very lean after that. So we installed a fuel pressure riser and that fixed the problem (as well as replaced two bad spark plug wires). So we went back out and we took a few pulls on the highway. The car makes a very very different sound after the stock redline and its not a gradual sound change, it changes sounds like it was on a switch to a higher note subaru sound, but a very good sound thats for sure (love it!).

Im am shifting a 7,500 rpm for now because we couldnt really tell if it was worth staying in a gear up to 8,000 rpm, it diddnt have anough power near there from what we could tell but we think this is due to intake manifold restriction and lack of fuel b/c the unichip is maxxed out for adding fuel. The 1/4 mile track wil help me determine this.

On the highway, we did a long pull in third up to 7,500 rpm and I looked at my speedometer and we were going 145 klm/hr (87 mph) in third which was pretty neat.

But the car still has great low end tourque, but when you hit the gas at around 4,000 rpm it pulls all the way up to 7,500 rpm amazingly. Its a different car, but its still subaru in terms of how it drives.

But after tuning with ben at lachute, we dicided that the engine could still be much faster with stand alone engine management, so Im selling my unichip and old zex kit locally. So the stand alone management will go in next week hopefully alog with the 9lb flywheel which I have, but it diddnt arrive on time for the engine install. The car will also make power up to 8,000 rpm (likley 8,500 if all goes well).

The unichip is not up to this task, if I had known i was going to go this way I would have bought a stand alone in the first place, but I diddnt think Id go this far, so at the time unichip suited my needs percectly. We can squeese 20-30% more power out of the car with stand alone easily I was told, it will make a world of a difference.

Anyway, i thought Id update you guys, feel free to ask questions!

Dan

Yes... please please post what you have done.

Have you done any actual dyno pulls or are you just tuning on the street?

MattDell · 04-29-2003, 03:31 PM

Videos, dammit!

BOY · 04-29-2003, 03:39 PM

Dan, 2 words... extrude hone

you're likely at the intake manifold's limit, port that sucker. Good job so far though!

dcoty · 04-29-2003, 03:44 PM

Heres the mods, and i am going to the 1/4 mile track this weekend on saturday, so that should be fun. I have no clue what it will run, but its going to be a comparison run for when i go stand alone management soon.

We tuned it on the street/highway and lachute is booking me for a dyno tuning session as soon as it opens here in montreal. Il post everything too. my buddy has a digi cam so he will do some vids for everyone. I cant describe the sound it makes!

strommung cat back 2.25"
random tech high flow cat
borla headers
cobb cai
UD pulley
Closed deck block
lightend/balanced/knife edged crankshaft
custom billet con rods from Oliver
custom 11:1 compression pistons from CP (coated for future nitrous use)
Bored out to 2.55+ litres (torque plate boring)
custom ported and poished cylinder heads
Cobb racer camshafts
ported/port matched intake manifold
Cobb springs
Cobb retainers
custom made stainless valves (3 angle valve job)
fully blurprinted
fully balanced
Tuned with Unichip
Redline set at 8,000rpm
9lb flywheel (14 lb flywheel right now, the 9lb came too late)
ACT clutch
STi engine mounts
STi tranny mounts
ARP Head studs...not bolts anymore.
Upgraded fuel pump
Fuel pressure riser

So, we will see what can be squeezed out the car with the stand alone (definitly more power and more inportantly...safety), but right now Im still getting used to it...100klm/hr in 2nd is different for me. Id give everyone a ride if I could!

Dan

dcoty · 04-29-2003, 03:47 PM

BOY- I did get the intake manifold ported out, but it still not so great, Tattoo Collector is working on a manifold for his car and eventually mine. That will be neat if everything goes well, that isnt an easy job.

Thanks guys!
Dan

BOY · 04-29-2003, 03:49 PM

Dan, retracting my previous suggestion

.

Have you thought about injectors? also, ditch the 2.25" exhaust for a 2.5" (you're one of the few RSs that NEEDS it) also, consider ditching the Borla for an MRT or brullen (or have a header built like I did).

NC2.5RS · 04-29-2003, 03:55 PM

WOW!!! That sounds like one amazing piece of machinery you have there. Congrats.

Crimson · 04-29-2003, 06:06 PM

dcoty
If you are ever passing though Kingston on your way to Toronto or something let me know I would love to see your car man.

Pakin · 04-29-2003, 06:08 PM

How much was the tunning @ lachute?

-paK +1

DoctorNick · 04-29-2003, 06:26 PM

yay! so you are going with engine management

good to hear that. Now you can also get bigger injectors and fuel that puppy! congrats!

dcoty · 04-29-2003, 07:49 PM

BOY- I like the 2.5" suggestion, I think i might need it I suppose (especially to really get the high end gains). As for the headers, i love the sound of my borlas, but then again, if Ive gone this far, why would I intentionally sacrifice hp becuase I like the sound of the headers...Ill eventually get a set of equal lenghts, btu Ill miss the sound!

Pakin- Tuning is 56$/hr, if you are a member of the montreal subaru club...you get 10% off. Its worth every penny for ben tuning the car, very worth it.

Doctor Nick- Ben has WRX fuel injectors on his supercharged RS and he has unichip for tuning, the only problem is he is running super rich at idle, he's removing close to the max you can with the unichip. We are going to see if the stand alone will fix the issue, if not...in go the WRX injectors and we'll compensate.

Thanks for the replies guys, its nice to know people care! We'll show them the power of N/A

Dan

Im nervous about the 1/4 mile though, I want good times so badly!!!

Whenever you get the chance to do a G-tech run or dyno your N/A behemoth, post the results ASAP. I'm interested to see how it turns out.

dcoty · 04-29-2003, 08:35 PM

Well, if everythign goes well, im going to the track this saturday, Im nervous, i want to get good times, but even if i dont, the new mangement sure will improve them!

Dan

jasona · 04-29-2003, 09:20 PM

You HAVE to get a video! I need to hear this! I was wanting to run mine to 7000-7500 when I went turbo.

Kostamojen · 04-30-2003, 02:40 AM

Im thinking custom intake manifold + TWE headers, 2.5" high flow cat with a 2.5" catback would add a bit more power at the high end

GooseMan · 04-30-2003, 08:27 AM

Danny boy, I sent ya a PM. Make sure you call me if you go draggin this weekend! I wanna come see THE BEAST!

And I'll race your ass on the strip

.....and get my ass blown away!

C-daleRidr · 04-30-2003, 03:11 PM

Damn, dude, glad she's up and running. It's been fun to keep up with this car. I can't imagine the cash-ola that's gone into that engine.

How streetable is she with all of this done?

dcoty · 04-30-2003, 04:14 PM

The car is extremely streetable. Still has low end torque for driving around, the clutch dosent bother me, but Ill tell you how it is with the 9lb flywheel, it shouldnt be too bad. the only downside is findign 94 octane in areas im not familiar with.

Goose! Sure thing man, I might have to work on saturday, so i hope napierville is open class time trials on sunday!

Dan

GooseMan · 04-30-2003, 04:22 PM

ok man! lemme know. I wanna see if I can beat my 15.3 I got a few years ago

Tattoo Collector · 05-01-2003, 02:54 PM

Well Dan, thanks for the fire. Once I get done with the 1950 Ford Coupe and the 455 olds motor that I have to do, the Subaru is getting my full attention. I think I will have the intake manifold all welded up for some prelim. flow numbers by the middle or end of next week. Have you heard anything on an ECU and wiring harness? I am still looking for those 2 things so I can run my engine on the dyno. Also, tell Ben I am going to need to call him and bug him about some stuff that he did with your car. I need to know if I should go with a bigger fuel pump or a fuel pressure riser or something else along with the unichip. I'll keep you posted on everything. You have intake manifold #2 once I get mine on my car and functioning properly. Keep in touch. Congrats on the car.

Nathan

joefocker20 · 05-01-2003, 07:18 PM

Yeah, you should get the TWE Header, run catless, and get a Brullen 2.5" catback. Personally, I'm glad I got the Borlas, my car received a pretty good kick in the ass after I removed the cat after I installed the header.
