is there a GIAC tune for the larger intercooled cars yet???

 

What real specs are you looking for?

 

Yes there is!

 

phone number to contact.....name?

 

LOL $20 short of $700 and no need for a group buy ...... I want a group buy on whatever your smoking to think that.

 

-heat transfer coefficient
-heat tranfer area
-log mean temp difference
-pressure drop
-intercooler efficiency value

Use stock IC tested under identical conditions as a baseline for comparison. Provide specs for stock also as best as can be calculated.

 

We never quoted a price of $700...we made a vendor announcement that the Helix Stepped Core Intercooler is having an introductory price of $679. After that it will go to a retail price of $749

 

I am sorry. I was laughing at the high price of even the intro offer.
I am sure there are some people still around that have that much spare change in this current consumer market but for the power and cooling rewards you get for the cost of installing one of these the cost/reward balance is just not there.

It is indeed a great looking design and the previous research you had told us about does appear to show that it is better than the ALTA and FORGE offerings.
I had just under $1k left in my car budget and naturally have decided to move that to more important purchases. Even if it was still there and I hadn't lost $1000's on my 401k I would not pay over $400-500 for one of these.

 

I designed this intercooler just after completing my 335i design. if you care to go to e90 post and do a search on Helix FMIC you will see all the data and forethought that went into this "similar" design. the endtanks are cast as you can see and the core is a bar and plate spec'd for .5psi pressure drop at 250hp. Prior to my designing the stepped core intercooler all intercoolers were either thicker or taller but rarely both.this intercooler is designed to take up the available captive area in front of the vehicle.

-heat transfer coefficient-I can see if i can get this spec from the core manufacturer but this spec is generally not given for intercoolers except for laminova that I have seen.

-heat tranfer area- I planned on providing this

-log mean temp difference- Ill do that too

-pressure drop- core specs given above

-intercooler efficiency value- I'll do those numbers as well

as i said if you care to look atb the e90 post data you will see we provide much more data than other intercooler sellers. on top of that the Helix 335i intercooler has shown to have the best temp drops in multiple gears and power gains of other available interoolers. These specific designs do not use off the shelf cores or parts they were designed from the ground up to work in each specific application in regards to dimensions and ambient and charge row fin counts and heights.

 

Is this Helix's response to my request for design data for comparision with other units?

 

No please read my edited thread above and also PLEASE either pm or paste the "other" competing intercoolers data here so i can make relative comparisons

 

Sorry, our posts must have crossed in cyberspace. I'll take a look.

 

Any numbers on compressor output temps if you have them would be great too.

It'd be nice to have all these numbers for all the manufacturer's ICs in fact...

 

Helix R56 Stepped Core Intercooler


Core Design
Prior to the 335i and the R56 Mini stepped core design you had the option to either go Taller or thicker with the cores. In my design process I measured the captive areas in the front of the bumper in both depth and height and went about designing an intercooler that took up all of this area. The end result is an intercooler with 53% more frontal area as well as 50% more core volume. now about the core, we were not constrained to an off the shelf core in regards to ambient and internal fin count as we custom spec'd the core to this application. the core in the Helix FMIC is a single unit stacked up to our specifications in regards to ambient and charge row height and internal and external fin count. since our core has more volume I could increase the internal fin count to remove more temperature and still meet the targeted air flow and pressure drop for this application. as you see by the AIT data logs the intercooler works amazingly well.


Endank design- all endtanks are not created equally, air likes to flow in a smooth curved radius as you can see the Helix FMIC has rounded endtanks that are cast.
DCICsideview.jpg?t=1196359252

Install:
Fits in stock location- YES
requires no cutting,removal and/or permanent modification- Yes

Design:
More core volume than stock- Yes 50%
More Ambient face than stock- Yes 53%
More charge rows than stock(5)- Yes 12
Bar and Plate construction- Yes

Performance:

STOCK turbo outlet temperature 245 degrees F(estimated using a 65 degree ambient and 65% compressor efficiency at 15 psi
Temp drop from 245f to 111f(peak temp) in 4th gear run = -134f degree drop

HELIX TEST turbo outlet temperature 253 degrees F(estimated using a 71 degree ambient and 65% compressor efficiency at 15 psi
Temp drop from 253f to 89f(peak) in 4th gear run = -164f degree drop, 21% better cooling than stock

AIT temp- 30 degree drop over stock
pre and post intercooler temp drop- 164 degrees F
Intercooler efficiency- 80% - 21% improvement in efficiency over stock(59%)
Core pressure drop spec is .5psi at 250hp(400cfm) airflow

 

Thanks Mark!

 

Just one more figure we need to know: the fudge factor for all the reported numbers...

 

Thanks for gracing these boards with more smartass comments, chickenplucker. With your last post, I got to wondering what your core motivation was: were you interested in an intercooler for your car, wanted as much information as you could get from the manufacturers, and found that Helix provided false information? Or, did you find that the information that Helix provided was incomplete compared to other companies offering an intercooler? Or, were you merely showing off at our expense with snied and condescending remarks, designed to make you look technically astute?

In looking at your other posts, I'm going to guess the latter.

 

Might want to take out the we your the only one with the axe to grind.

 

No need to fudge anything as we designed this intercooler to be the best from the word go. if you care to look at the e90post forums and our testing it matches EXACTLY the results our customers get in their own independant testing

 

Gentlemen, I was just engaging in some good-natured ribbing, as I tried to show with the smileys. I'm very sorry I offended you. That ws not my intention. I have no reason to doubt your integrity or honesty. I apologize if my remarks seemed snide or condescending, they were intended to be jocular and facetious.

I am actually very impressed with how forthcoming you were with the info I requested, as it is very necessary to intelligently compare competing products. I, and I am sure many others, greatly appreicate your willingness to respond when questions are asked. In the future, I will limit my remarks to the subject at hand.

Sincerely,
Don S. (chickenplucker)

 

I've been thinking about the recent exchange between myself and the anonymous Helix poster and have several observations. I grant that any post, due to the nature of written communication, can be misinterpreted as mine was. Sometimes humor does not come across as intended. However, that being noted, I think the response by Helix was completely out of proportion, especially since no attempt was made to clarify if I was jesting or being a snide (spelling corrected) smart**s, as anonymous so eloquently described. Even after I publically apologized for offending with my remarks and sending an additional PM to both Helix posters, no effort was made by Helix to acknowledge my efforts to make amends.

I find that highly unprofessional as representatives of Helix in this public forum, and as a human being simply ungracious. I interpret those characteristics as representative of the company as a whole and have decided there is nothing Helix produces or sells that cannot be sourced from another manufacturer. I have no intention of purchasing any products from Helix, either products they produce or other manufacturer's products they sell on their site. There are too many other places to spend my money where the sales reps do not insult potential customers.

 

No one has answered you? no one has answered anyone as everyone has been away for the Holidays. I have your pm in my box and had all intentions of responding back to you in a positive manner. I just think this thread went wayward starting with your pokes at "HUMOR" where is the humor in a product release? with that being said I personally accept your apology and in the future i hope threads can stay on topic. this thread is about the Intercooler release and the data pertaining to that not anyones Emotions.

Happy Holidays,

Mark

 

I've seen this coming from a mile away, but it still appears you're not getting the point. From your first post you were on the cynical offensive:

Helix asked for specific requests, and followed up with acceptable answers. Your rebuttal was this:

If you were trying to be funny, you weren't. Helix isn't hiding being an anonymous mask, like you assert, they're defending themselves and their hard work on their new intercooler from your trolling attacks.

If you were genuinely interested in their intercooler, there wouldn't be the tone of remark you were making. We all know you're not going to be their customer. If I were still in automotive aftermarket sales, I wouldn't want you as a customer, as it's clear you'd rather grind your axe than be satisfied with the answers to the questions you asked. You think Helix is being ungracious because you give them a hard time after answering your snide questions, yet you'll probably fail to understand that you have no clout, no good history, and only a few "misinterpreted" hissy-fit posts to back up your point of view.

You honestly took the time to come back to this post a week later and bleed of your steam, but why? To attempt to discredit a valuable and honest aftermarket company with a HUGE satisfied customer base over many years and many brands. Please, get over yourself and your failure to bash their product with no knowledge of it.

Want to put your money where your foot currently is? Buy all the current R56 intercoolers and do a group test. Produce all the same parameters you demanded, and publish it for all to see. You will then have redeemed a small percentage of dignity lost by your continued unfounded bashing, even if you tried to play it off as misunderstood humor.

Regards,
Ryan

 

Well said Ryan.

 

Wow, being as a good front mount for a 1.8t gti as about 1k, I am pretty sure this is good value
Wow, I hate people who live to find something to b**ch about. Just chill. Its the internet. No one cares.
