also keep in mind our car has about 25,000 miles and we made our parts when the car had 250 miles about 11 months ago - we have tested our products longer than anyone else - thus why they may look a bit different

 

Garage G Force

Oh ok. So your design keeps the manifold away from anything that could melt or catch fire. Good to know But...the Garage G Force header looks like it has provisions for a heat shield (the studs sticking out from the tubes). Couldn't that be a way to keep the heat in the header and away from everything else?

Don't get me wrong here. I'm not knocking your manifold at all. Like I said, it looks great and it has the testing behind it. I'm just wondering which design would be better for the most power and the best spool up.

Is it that you tested both designs and found your current one to perform the best?

 

thanks for your post . Yes our manifold keeps away from anything and everything that will in mess-up in time . Even using a heat shield it still transfers heat and that heat in many months of usage WILL get to everything back there ! We also found out that using a design like that will heat-soak the cold turbo housing and discharge pipe within ONE pass at a track . We have found out over MANY months of real world testing that the best design is one that keeps VERY low and has short runners . and yes that design is one that been done MANY times over , we in-fact have done many manifold like that for other cars and they will work great just NOT on the Evo X because of its location and the parts surround it . And yes I can safely say that I know our manifold design is not only the longest tested but the best possible design for this application .

 

just a Q ? 1-3-4-2 as a twin scroll are you finding any issue's ??

Personally I like to see the firing route followed ?

COBB TUNING all the way

 

"But aren't the 1-4 and 2-3 cylinders supposed to be paired? "

nope, the purpose is type of manifold, to have an equal length, nothing to do to being paired.

 

We're looking at the end result which is power , looks are second and firing order goes out the window if it doesn't work ! We have built and tested 4 manifolds and our current design is the best possiable design for the Evo X ! It takes into account heat transfer to its surroundings which no heat shield will help if the heat shield its-self come close to those vital parts- I know because we already tested this out and it works great until the everything back there gets hot then all that work goes out the window . Having longer runnings also allows for lost of heat in those runners and lost of heat is lost of power . Then the manifold sits too close to the cold side of the turbo and outlet pipe , those are heated after a pass or two at a 1/4 miles track and imagine how well its will work for those that do autocrossing , timeattack or other types track racing when you have to get on and off the gass for 10mins to 30 mins - you start the race with 400hp and about 5 mins later you have 300 and you're wondering why everyone is passing you . We have tested this out over the last 25,000 miles we have had our car , and we found only one good way to get the job done . Any manifold you make thats made well WILL 100% work , the question is how well will it work on cars driving for more then 10-12 seconds - thats the key to making a great product that everyone can use

I am sure if the data backed up the design then the question is irelevent .

www.adrmotorsport.com We have 1 or 2 EVO X'S maybe you want to send us a sample .

Also our Drag Car www.magnusmotorsport.com JR Motorsports EVO

Our Inconel Header http://primarydesignscouk.site.secur...-evo8-drag-car

I will have ZERO issue with anyone from a ligit company testing out our unit , we did our testing at the local track over the last few months . I see that your sig says UK but if you know of someone here in the states I'm willing to work things out . We will have our own numbers soon , we tested to actual real world numbers at the local track and I'm confident we achived that months ago by runing 11.8 completely untuned . We now tuned our car and run an 11.9 holding 21lbs and spiking 26lbs , we'll try to do some passes holding 28lbs and see what we get .

OP, I will send you a downpipe in exchange for a shipment of alcapurrias, bacalaitos. and piononos

Thanks for your post It's nice to see a company take the time to go indepth and explain why their product is what it is. And the numbers can't lie...11.8's without a tune? I may just have to pick up one of these manifolds

 

jajjajaja ok,is a deal

 

Yes sir , some have made an attempt to bring down that accomplishment but the fact does remain that we made tons of power without a tune - so the parts are very well made and in that we sure do lots of pride ! We will be making the manifolds very soon we did get in the elbow we need to make them with .
