Here is my questions posted yesterday to Scdyne and the answers I received today !

Questions

1: Is a header for the Cobalt SS/SC is available right now ?
2: If no, when will it be available ?
3: Can you send me by e-mail some dyno graphs ?
4: What price including shipping in Canada ?
5: Is it better also to buy the ScDyne gasket ? At what price ?
6: If I order right now, how many days to receive it ?
7: Do you currently make (or buy for your maker) a good amount of these headers ?
8: Is the bolts or stud fit perfectly with the engine block and the down pipe ?
9: Does the header can be used with the stock downpipe, or since the collector is bigger than the downpipe must be replaced ?

Answers

1. Yes the header is available right now. Our current production run is expected to be back from ceramic coating by the end of the week, ready to be delivered to the public.
2. Available by the end of the month at worst.
3. There is one Dyno on the site now and one more will be posted as soon as we get it online later in the week. It was done by an individual as an independant test.
4. Shipping to Canada is a little more expensive, but I think I'm going to re-evaluate the retail price so it will be around the current $425.00 shipped.
5. I'm probably going to include the gaskets now in the new price. It's copper vs. multi layer steel so it's a toss up.
6. If you order now you will get it around the first week of september. BUT you'll also assure you get one from this batch.
7. At this time we purchase 15 at a time so they go fast, but I'm sticking to that low of a number to keep an eye on production. I have had problems with them from the beginning so until I get a few batches out that all look the same with no come-backs, I'm sticking to low volume production numbers. It puts the supply below the demand for the most part, but I can control quality that way.
8. The stock head studs are used, but smaller nuts (Honda/JET Style) can be used if space between the stud and primary is a problem. They are hand built so there are differences in every one that is impossible to prevent so we provide the hardware to address that. The exhaust side uses bolts and nuts over studs for a better seal.
9. It's a direct bolt on replacement part and fits up to the stock down pipe. If you choose to remove the cat and use a straight pipe of a larger diameter then it's going to make power, but violate emissions laws..

so imo this would be a better purchase since it is cheaper than TOG header. 425 shipped and it is a direct replacment. just my .02 correct me if im wrong sum1 cuz idk this is like a question.

 

Sweet! We have a header now! But Idon't know how much better than stock it would be. I'd like to have a 4-2-1 header made for us. One step at a time, though! I think that, combined with a 3" catback would be a nice combo.

 

Sounds good, I'd like to see that dyno.

 

i would seriously wait till the TOGs come out before you go buying this other header. There are other, cheaper, headers in the grand prix market, but no one really recommends them. Spending the extra money on TOGs is well worth it. Before everyone gets all excited about a header, wait till you see what TOG has and then make your choice.

 

WOW! I just posted on RLF too!

Please understand that while just bigger in any profile of header will make more power, AND removing the CAT will definitely make more power, our goal was to design a CARB/Emissions legal product that fit within the area of the stock component. This will strike up much debate, but it’s been proven time and time again in EXACT engine profiles as the ECOTEC and Eaton S/C that a 4-1 header is much better suited for overall performance than any 4-2-1 design. Most of the available information about header design does NOT directly apply to situations when manifold pressures exceed 27 psi absolute during exhaust pulse events. In simple terms N/A header theory does not apply to boosted header theory.

I spent a lot of time processing CFDs for a number of header designs I came up with, some impossible to make and some impossible to install. In trying to find the best answer for performance and getting the CAT lit off as quickly as possible I came to a design that is almost the exact same as the header you see. Dyno tests validated how close the physical header came to the CFD model and it turned out to be about 95% accurate.


There is no comparison between the TOG product and mine they are designed based on different requirements. There is no doubt that the TOG header will be exceptional in build quality and design, but it’s like comparing apples to oranges.

 

hey guys i would like to let everyone know about the issues with this dude. the redline owner's have went through some serious issues dealing with this company. here is just one simple thread concerning the quality of the products and service

http://www.******************/forums/...ead.php?t=3996


even the redline owner's said they hope everyone gets the "real" info about this company.

 

just my .02 but the Dyno chart on his site looks as if it says the header gives a 20hp gain and it looks like 11-12 tq, it seems a little high on just the header alone as for as HP goes, .

Example if you look at the new DC headers for the 350z they dyno at 12.2 HP gain with DC exhaust 10.4 without.

Just my .02 cents on Scdyne header.

I would stick with TOG or maybe even RK whenever they get around to making it. Even DC in the real long run.

 

Well hopefully at least someone on here tries it and then we will know for sure

 

one of the guys at the redline forums actually had to get his header re worked at a machine shop cause it was uneven. that plus the fact you can't use the stock gaskets, and some of the other people have had issues with leaks as well

 

From what we've experienced on the RL forums and consitantly expressed concern over was the customer service. Everyhting seemed to be promised "next week" and turned into 6 months of crap because he didn't want to let a little bad news turn us away. Instead, he just kept putting more news out and delaying, with whatever problems he incured. If he had simply said that he was having problems with the people, and given some sort of realistic time frames, I think people would have been happier. Most people that used the header won't deny the performance from it, goofyguy on the RL forums said "I couldn't really tell a difference once I put it on, but once it came off, I could definately tell." I would like to see pictured of this new production model, being the others were some sort of "pre production" model, and see how the fit and finish is. The ones that people received earlier, just left a lot more to be desired. Having yo clean up an uncoated header that you payed $435+ for did not make anyone very happy at all. JMO on things, because I was well on my way to purchasing this header when I foudn out the troubles others were having. Just don't send money till he can confirm he has them in stock, and you should be fine.

 

Once a few of the current SCdyne header owners take possession of the updated header, news will spread fast as to the quality and craftmanship. [READ: Good or bad] As quickly as time and production permits all the original headers will be replaced with the updated model.

304 SS was a time hassle for production, as it required only TIG Welding and great attention to detail. Switching to mild steel allowed the header to be placed in the normal manufacturing schedule and lowered production times from 1 header a day/3 week max to a run of 25-50 in little over a week. Now we can keep on top of inventory, order more and get delivery with only a few weeks lead time instead of almost 2 months.

At my end of the whole task I'm doing everything I can to get them made faster and better with a lot of design improvements and details related to fit and finish. Also we plan to pick up a few retailers in the next month and that should take care of any customer service issues.

While I can't get online and update people as often as I would like (I do work a full time job too design/testing UAV's) I try to as often as I can. I'm still making sure that every owner has their concerns addressed and I will not just turn away or make excuses about the first run of headers.

Bottom Line is that the header exsists, it's available now and even with issues I'm addressing them and finding solutions to prevent them from happening again. That's more than can be said about just about every other company.

 

i know alot of the gp guys here in phx , and tog isnt the best name with them

but all the headers they have for the g/ps seam to have some kinda problem from time to time

 

really? which guys have a problem with TOGs? Did they get the coating on them? The only "problem" with TOG headers on a GP ive heard of is that you need to bend the tranny dipstick to install them. Their coatings are guaranteed for life, so if theyre fading, they can send them into TOGs and get them recoated for free as long as theyre the original owner.

 

Until the TOG header is out you can't say anything about it. Let's not run off a vendor before they have a chance to offer a product just because of hear-say.

 

i have one of scydne header and yes it does have some issues but it was an experimental header 6 months ago when i first got it since then he has promised
to send me a new one that is redesined with all the problems fixed ? alls you can
do is have faith in some people somtimes peoples pateions run low we will
see..... i cant wait the hp is really good you can feel it all the way throu the power band.
dont knock the hp we all want hp where ever it can come by .

 

yes we are, but when multiple people in other forums express concern and specificly state that they hope no one with a cobalt ss goes through what they went through, and wants everyone to be warned around here, that deserves a a serious concern.


just wait guys, why take a chance, the TOG product will be out shortly and you know they have excellent customer service. why take the chance with your hard earned money?

i was even thinking about getting the scdyne header almost 2 months ago, until i seen that it had almost a 100% complaint ratio from the customers (people that posted) plus the pictures posted just showed poor product quality
