Thumbs up

WOW! That's some pretty good numbers. What kind of turbo kit are you running? JCSports, Minnam, other?

LaterZ!

Penphoe - HOK is running a Gen 1 JCS kit, but the turbo is a T28/T3 with a special impeller grind.

In the next week we'll be installing some more engine manganment to increase the revs to 7000rpm as well as mapping a new ignition map. That way, HOK won't have to shift into 5th right before the end of the 1/4 mile as well as increase more low end response. These changes may possilbly push the car into either the high 12's or low 13's. (Remember, HOK ran an uncorrected time of 13.7s)

Remember, up here in Calgary we're 3500ft above sea-level (or 0.663 miles above or 1061m above)

GTB, that sounds good.

But remember, altitude corrections don't apply the same to turbo charged cars. Turbos are based on differences in ambient pressure, and thus automatically compenstate for much of the altitude change.

tulit - Yes you're partially right, Force-induced cars aren't as heavily affected as N/A cars at alititude, but they're still affected by thinner air etc.

There are many factors when you're at altitude. You have to remember, this was done on 1/2 tank of 92 Octane gas + 1/2 bottle of STP octane booster (which I think didn't do too much at all).

Good times HOK.....

With a bit more practice, you times should lower...... since you should improve your 60 times.....

With a turbo kit, you should be getting 1.8sec or a bit faster.....

Keep posting the info......

Yeah... I thought this as well.. but this thing is that the EJ22T has less low end torque... it feels dramatically different to my inaccurate butt dyno...

Since the 2.5 has gobs of low end I believe this is what made really good 60 ‘ times… I was also trying to be a little easy on the tranny… so.. I was slipping and wasn’t doing a really good job of it… I was happy with 13.7 so its ok… If you tell me that I can get better times with my current setup… then I’m happy hehehehe

But hopefully we can get 12’s in a year or so,. At this elevation. But I’m really antsy about the tranny… no money..

Most of Calgary is around the 3000ft mark. Is the track really 500' higher? Were you racing west of Calgary? Curious.

markus - Actually, elevation gets higher than 3500ft as you move west. 3500ft above sealevel is measured @ city centre. This was taken straight out of tourism guide.

Jack,

No offense to the Tourism Guide, but it's dead wrong. I've done enough surveying/engineering work to know that Calgary City centre is almost bang on to 3000'

Anyways, we're getting way off topic. 13.7 is awesome!!!! HOK just needs to improve that 60' time and you'll likely shave another 3/10ths off the 1/4.

Cheers,
MB

Great time man!

Are you running the stock EJ22 block?
What kind of EMS are you going with?
I really hope you hit the 12's some day my car will be there too!

markus - That's quite interesting, I guess it's time to write to the editor of the publication. IIRC, Calgary's elevation increases from E->W, lowest point being downtown.


RageHardIntoTheBendies - HOK is running the EJ22T w/ EJ25 SOHC heads and 440cc RC injectors. As for engine management, running the stock ECU, SAFC, TC2 (was). We're taking out the SAFC in favor of the Unichip.

We'll be eventually using the Unichip to bump the rev limit 8-12% somewhere in there, we'll be able to break into the low 13's and high 12's with alot more ease. Everytime HOK get's very close to end of the 1/4", he must shift into 5th to avoid hitting the limter. In fact, he's actually hitting the limiter in every gear, hence he's only shifting at 5500rpm to get the 13.7 run.

If he can practice launching faster (keep in mind that he's trying to baby the tranny till he has more funds), lowering the 60' times should yield a run of 13.4-13.5s. With the higher rev limit, doing high 12's shouldn't be out of the question.


[edit for typo]

Great thanks, very interested to hear how the Unichip works on an RS, don't think I've seen that done before, if it works well I may reconsider my additional Injector plans, mmmm

Great stuff guys, keep up the good work!

RageHardIntoTheBendies - Yup, no probs, we'll be keeping everyone posted. First of all, we have to "un-install" the SAFC and TC2. We got the harness in for the Unichip this weekend, but won't be able to do anymore until next week, as HOK won't be in town.

Anyways, several main advantage of the Unichip over the TEC2 exists : The biggest being cost. (about $9XXUSD for the ECU w/ boost and rpm modules)

Another good thing is that you can adapt up to 440CC RC injectors on your stock fuel rails and FPR, and use the Unichip to control them. There's still 2 channels on the Unichip that allows for the use of an addition 4 injectors to be driven (ie, you can use your stock injectors again on the intake tract somewhere to produce a total of 2880CC/min (at full static), equivalent to runing (4) 720CC injectors. Of course you'd only want to run at 80% duty cycle which is equal to a max of 576cc/min. vs: the 550CC upgrade that Shiv has, this is way more economical. (the 550's running @ 80% duty cycle is equal to 440's).

However, one big benefit to Shiv's set-up is the fuel rail, which distributes fuel more evenly vs. the stock rails.

In the case of referencing the amount of air going into the engine, the MAF units are alot more accurate vs. MAP systems. This is outlined in many cases (you can check some back issues of SCC, they have the explaination there as well). The Unichip allows you to retain the more accurate MAF. Ofcourse, depending on which turbo-kit you go with will determine the longevity of your MAF unit.

In anycase, this is going to be an interesting experiment.

So the unichip allows additional injectors also? wow that sounds awesome!!! can you run low impedence injectors on the additional channels?

This is very intersting.

RageHardIntoTheBendies - I'll have to check on that... not to sure at this point, but it will drive extra injectors. If memory serves me correctly, it drives up to 8. But most likely only 4.

Yes... i was think about putting in the Unichip... but it seems a little too difficult without some help from APS or cobb... cause I guess thats why Cobb didn't want to give people plug and play harnesses. go figure... but the car works fine now... and no det.. so... I'm still considering. If I can get better launches or i get more horsepower I will need to spend more on a new Tranny!!! maybe... so i'm at a Catch22 get more horsepower=need to spend more money on tranny.,.,. booooooo

Guys, please tell me more about the Unichip.

Could i make it work with my MY00 EJ25 turbo setup?
Right now I'm running the basic 5-6 psi piggy back setup being zener diode, RRFPR, wrx fuel pump, TMC1 boost sensitive retard timing controller. I've got it all dialed in quite rich and am retarding quite a bit, which is safe. Though, for more power, I definately want to go to the Tec-II or some similar engine management system. So.. would the Unichip work?

Rick Hunter: The unichip sounds like a good match for your setup, it will allow you to run larger injectors and raise the rev limit if want too. I would be confident running up to 10 - 12psi on a unichip, after that a TECII would probabley be a good idea as it has the multi toothed wheel/sensor for finer control etc.

I know cobb is also looking at this.

Rick Hunter - With the Unichip and also their boost module, you can use their 2bar or 3 bar map sensor to over come the "diode" problem.


RageHardIntoTheBendies - On the stock EJ25, it's not recommend to rev anymore past 6500rpm with that kind of boost level, as you will throw a rod. With the EJ22T, you can rev all the way to 7250rpm's but the stock EJ25 heads (SOHC) are only good for 7200rpms safely until they start having valve float and irratic operation.
