Excited? I'm drooling over this! My dog is starting to look at me funny...

 

I think you might be sitting/standing too close to your dog's dish of dog chow
And your dog is wondering what you are up to with your drooling. Obviously no good.
(just kidding)

This is good news Eric and something that sounds quite feasible and workable as a logical mod for those with the 19% pulley or planning for it. Otherwise a larger intercooler would make some sense for the 19% pulley (what happened to the RDR intercooler we talked about in January???)

I really like that fat torque gain. More HP isn't as easy to use on an island with no long track and not very many miles of roads that aren't congested or patrolled.

 

Minihune,

I can't believe the number of posts you have. You have almost 250 times the number of posts than the average user on this site (not 250%, but 250 times). That means you spend the same amount of time posting on this site as 250 people normally do. Cool to see someone so excited about Minis.

I did talk to RDR about their intercooler, maybe about 3 weeks ago, and they were still working on pricing of the unit, and said they would have it available shortly with numbers. Supposedly it is all ready, and the testing has been completed. I haven't heard anything else.

Maybe this can be a Helix Stage II package. Maybe give us a deal on a combined purchase of 19% pulley, injectors and ECU.

 

I'd sign up for that! An injector and intercooler upgrade, combined with an ECU calibrated for use with the 19% pulley, sounds like the ideal low to mid price ticket for max torque gains. It solves 2 of the big 3 worries I have about the 19%- excess heat, and fuel starvation at higher revs. With those two covered, I'll probably be ready to risk occasional belt failure. After all, I can keep a spare belt and a tensior tool in the boot, eh?

 

Hmmm... I'd expect you're probably sworn to secrecy if my guess is right, but did the bourbon-sipping glasses get set aside long enough for a prototype MIN-com to escape Ross-Tech's lab?

 

Eric -

That's what the Nuzzo crew has said from the beginning.

 

nuzzo and team has seen a lot of track-side time; by that I mean the side of the track.

 

Yes they have! But very early on when we were all complaining about the pig rich A/F curve they were running Motronic with a standard pulley to an 8,000 rpm redline. They claimed that their experience was that the richer mixtures at high rpms were producing the most hp. And all the ECU traps didn't exist on their car. Given the intake temp problems they had I thought it was that they needed the fuel to keep the engine together at the higher boost/rpm levels. With their use - long races at high rpms - that would not be out of character.

Eric's comment does fly in the face of your (more normal) experience. A nice, reasonably conservative A/F ratio should produce the most hp at the top. Maybe, even with that slightly leaner mixture we are tripping the ECU traps and forcing retarded timing and fuel dumping. JLM, you've taken the fuel dumping part of the equation away from the computer but the timing trap is still there. I remain surprised that the ECU flash guys didn't bypass the failsafes right up front.

Eric - does the ECU still retain the failsafes with the GIAC flash?

 

Yup. You don't want to disable knock sensors: bad things could happen if you filled up at a Mexico City gas station with what you thought was 93.

If we ever see some good numbers from a big intercooler, we'll definately put it in a stage II kit.

Aside from the screwy on board computer milage numbers, the only risk with big injectors is if your car is improperly tuned. Otherwise, giddyup.

 

ayee...yo helix doesn't you think them morons is too far gone? i mean wots timing?

 

Info on this?

 

15% is ready and available. 19% is not completed yet.

This is a link to a thread on Mini2 that talks about a new JCWorks upgrade. It caught my eye because it sounds very similiar to what might be had by going with the HAI, 19% pulley, the GIAC [19% version] chip, and the larger injectors. Could be that the 'Poorman's Works Package'!

 

Could be, if and when the 19% version of the GIAC is released. Stay tuned.

 

I'm not only tuned, I'm HIGH STRUNG! Eric has me on his list to call when the parts are in place!

 

Except I'm sure a 19%, GIAC, intake (+ exhaust) will blow even an "upgraded" JCW away. :smile:

 

Having driven close to 2,000 miles with the new GIAC, I would have to agree with greatgro. I'll likely upgrade to the 19% as soon as that GIAC is available.

 

Well, I'm getting giddy. My next door neighbor just got a new JCWorks. I am anxious to see how the cars compare. He needs to do the break-in I'm running the 19% and HAI now and would need to get the chip & injectors, but this should be fun. GIDDYUP!

 

Sorry if this was covered but what is the air/fuel ratio with the GIAC?I read an article from European Car Magazine where they were having an odd problem with their MINI. The ratio was way off to where it should be so they brought it to Evosport for further testing and these were the results afterwards.

4500rpm-13:1 range, lower 12's by 5000rpm, a little past 6000rpm 11.8 to 11.9:1 air-fuel ratio. On 91 Octane. The leaner mixture produced substantial gains. But again, their car was having trouble to begin with.

 

Ryan:

These cars are a little counter-intuitive. They do run better down low with 12.5 to 12.80/1 ratio, but to make big top-end power, it needs to be pig rich, presumably to cool down the intake charge. We have not seen power by leaning the car out up top.

Eric

 

Are we any closer to a Injector & 19% solution yet?

thanks,

James

 

The battle is still to find injectors that make financial sense i.e. make it worth the money to do the chip. I think that I may have found the perfect ones yesterday. We'll have to see what prices I can get.

 

how large do the injectors need to be?

 

What was wrong with M7's injectors? I heard they were the same as stock, but rebuilt. Those were $400. Add that to the $399 for the GIAC, and you are still ahead of the Unichip.

One thing to remember with the injectors. Your mileage calculations on the Mini computer will be off. Not sure if the GIAC can reprogram this, but I heard aftermarket chips didn't have access to this functionality.

 

I've been running the GIAC chip for a few weeks now, with my 15% pulley, HAI, One-Ball, etc. The difference between the GIAC and stock isn't earth-shattering, but it feels pretty much the way Helix' dyno graphs show. Nice improvement in low end torque, that continues to the higher rev band as well. I've had the opportunity to run other chips as well, and the GIAC seems to deliver the best combination of power and price without the problems that some other solutions have had.

I'd still love to see a dyno day comparison between different chips on the same car so that the playing field pecking order can be established once and for all. It would probably be best to do it at a shop that doesn't sell MINI parts, but one that knows the ins and outs of dyno testing with an emphasis on repeatability. AWE tuning comes to mind.
