Helix was working on a 19% with GIAC combo I thought. I serched but couldn't find any news on this? Eric if your out there any progress?

Thanks,

James

 

Eric can we get an update on this, I have a 19% pulley and is waiting.

Let us know if any progress was made and when we can expect thisw upgrade

And don`t forget us with the 17% pulleys

Paul.

 

Both of you... I wonder what the percentage is of people with the 3 different size Pulleys. Sounds like time for a Poll..

 

The tuning for the 19% and larger injectors is complete. The program and injectors are actually available. The problem is the price of the injectors right now. Helix is trying to source a cheaper yet still high-quality source. Even with the current expensive injectors, the package cost is less than some of the ECUs out there such as the Unichip.

I think I'm going to hold out a bit for less expensive injectors. But with 60k miles on the odometer, I'm getting to a point here with diminishing returns. How much longer am I going to keep this car and how much more money do I want to put into it. I'm hoping Helix finds injectors within a month. Then it's a no-brainer for me. If not, I'll have some serious thinking to do.

 

Yup, the tuning is done, and the results were excellent: On a bone stock '03, the car dynod at 149whp, on GIACs Mustang MD500 load dyno, observing proper dyno techniques. We then installed the 19%, injectors and GIAC flash and produced a repeatable 177-178whp. That's run after run, with proper dyno techniques, datalogging, and atmospheric condition. Same car, same day, same dyno, on 91 octane gas (boy do I feel sorry for you west coasters: I bet there's a bang-up market for tolulene out there). There were no other modifications to the car before or after our installation. I rarely post dyno numbers, because of the pitfalls of comparison to other numbers floating about on the web. Let's just say that these results are substantially better than a 19% alone, especially the area under the torque curve is improved, which is much more important than peak numbers for street driving.

If you are interested in one of these kits, give me a call and I'll give you the details.

 

Erik,

What is the cost of the injectors? What size did you get? Even the $400 for M7's injectors with the GIAC and 19% pulley is still a really big steal. Yeah it would be great for the lower price, but <$850 is still a great deal for the increase in power and extra headroom that comes with the kit.

What were the torque numbers? The GIAC really gave good torque numbers on the 15%, so I was really curious what they were on the 19%.

 

I already have 400 injectors from M-7 and lots of other mods, I need to know the price GIAC and how to order??

Call Helix. Also ask what size injectors they tuned the GIAC with b/c that will matter. You don't want to use different size injectors than what your ECU is tuned for. Although I guess you're currently running injectors that your stock ECU isn't tuned for but I wouldn't recommend it. Bad things can happen...

 

What are the new JCW injectors flowed at?

If you up'd for the JCW intake you get the larger injector au gratis.

 

I believe the JCW injectors aren't much bigger than stock. And the JCW intake might cost as much as the injectors!!!

 

They are only about 12% greater flow. Not a lot like the M7 injectors. I want to say they are 286cc.

You don't get the JCW injectors with the intake. You can only get the JCW injectors as part of the JCW 210 upgrade kit, and you can only get that kit if you already have a JCW 200 kit installed. Otherwise you have to purchase the entire JCW 210 kit and that would make for some pretty expensive injectors.

The standalone JCW intake, is just that. A stand alone intake, nothing more and nothing less.

 

It is okay to have larger injectors than what it is tuned for, but probably not a good idea to have smaller injectors, all most likely the ECU will compensate, but there goes your performance. I would think that Helix didn't tune with anything greater than 400cc, but it would be interesting to here what they did tune with. I think jlm has 440cc injectors, but that is the largest I have heard anyone using.

 

I have a line on factory injectors with perfect fit, size and flow for about $110 apiece. They are the injectors that we used to tune the GIAC for the 19% pulley. For engine safety reasons, I prefer to install these injectors on this kit.

I have much respect for M7Peter, but we differ in opinion on this one. We have talked about it a couple of times. Re valved injectors run the slight chance of having a distorted spray pattern, or worse, just dribble. If one is fubar, the car may run okay in certain circumstances, but you can end up running lean in one cylinder and bye-bye piston. The factory (Siemens) injectors are pricey, but they give me peace of mind.

I have a few injector options that I'm still looking at, and you can be rest assured that I'll spam the world over when I find that smoking deal.

 

The JCW injectors are 282cc versus 265cc for stock.

 

At $110 each for new injectors with no core charge, I think there will still be a lot of takers!

Smoking deal or no, over our last few phone conversations you've already saved me a huge chunk of change. :smile: Knowing what not to buy leaves change for getting more of the best bits!

 

GIAC is also working on a race gas program for 19% pulley and larger injectors.

 

as i recall, stock are 330cc; jcw are reported to be 360? and M7 is saying 400 for his

 

So I was pretty close. Erik, you might be right. The numbers that Miniac is showing came from an e-mail posted on Mini2 that came from JCW. But they have been known to be off as well.

 

Stock= 340cc

JCW= 380cc

M7= 400cc

The big question is....why do you need a 380cc injector on a 200hp JCW car?
The stock units are good for 230-240hp........
We sell the 400cc units for Nitrous and other high Hp, hard load applications.

The email from the "Chief Engineer" at John Cooper Works stated:

Sorry, I confused flow with capacity

jlm was at 185whp I believe when he changed out his injectors and it made a big difference.

 

Hubie chose injector size based on wideband A/F readings on the dyno. With the ability to pull back fuel as required in the lower rpm ranges (apexi), he could add still fueland trim as needed above 5500 and not max out the injectors. I'm sure there is some headroom with 440cc injectors...that is what Hubie is using in his 250whp twincharger.

 

GIAC has a flow tester, and got 330cc for the stockers. We are utilizing 380cc injectors for the 19% pulley. With the 19% and stock injectors, we were not running out of fuel: the A/F is peaking at 13.2/1 at stock redline on the dyno. It just wanted more to make big power. Thanks to a prototype scan tool from a secret company, we were able to see that the injectors were at max pulsewidth throughout the second half of the runs. By adding injectors and tuning it with a flash, we were able to give it all the fuel it wants--and it wants a lot--and also have the fuel trim at or near zero. JLM: where are your fuel trims with big injectors and a piggyback?

see hp claim post.

Hubie felt there was more to be had at the very top, but wanted to run it in a while before going for the ring. you can see a torque drop right where the A/F starts to rise around 6-7000.
