Good Afternoon!
Thank you for the interest in the JBS products:
Just want to clear a few things up
We had designed all our manifolds in CAD and looked for someone that could build them to our spec. TIG-ART came up top as they offered everything that we wanted as the manufacturer.
The first load of batches that came from TIG-ART had been fine and done exactly as we asked them, to ensure that the manifolds will not crack and perform to their optimum performance.
After the very first few batches the quality started to depreciate excessively: For example a batch of 5 K03/K03S manifolds were ordered and every single one was different to the other, position of the turbo flange and bolt holes started to drift causing these not to be direct replacement. But one of the worst was that we noticed some of the welds had not been fully purged - Using 3.5mm wall thickness and only having weld penetrating 1.5mm deep which then made this very pointless in the aim against cracking.
Not only this, we then later found out that they do not use any CAD software nor did they use any bench flow equipment, or CFD which was promised to us and lead times started to become very, very long causing supply issues.
We had tried with TIG-ART to resolve these problems but with no avail, they only started getting worse and worse which is why we no longer use them.
All our CAD information and our JIGs were taken from us to aid TIG-ARTs build but since these problems we have asked for our designs back, which they have not done and are now selling these manifolds on eBay.
We are going to continue to build tubular collected manifolds in our latest designs, this is all going to be done in house and expectations are that our in-house built manifolds are actually going to be cheaper.
As also mentioned we are going to be offering a cast version of the manifolds which are again going to be cheaper and offer great gains but yet very easy to fit.
I would also like to make it clear that ALL manifolds that were sent from us that had been built by TIG-ART were inspected and only the ones that were built to spec were sold.
I hope this clears a few things up, please as always feel free to give us a call on 01246 455005 if you have any questions.
Kind Regards
Mike
