8secSupra Posted November 30, 2006 Share Posted November 30, 2006 Bit of pay back for the DBB thread there Ian Like Ian said, I have never seen a BL manifold crack, I have however seen a few HKS manifolds crack, including Leon Green's twin manifold if you want to check Jarrett. Not to start anything Terry, but how many BL manifolds and HKS manifolds have you seen? Your correct, both may have a tendency to crack over time as they are tubular by their very design. But over my 12+ years doing this, I've seen many more "copied" manifolds have issues than the original HKS, which is why we stand by our HKS manifolds. The cause is pretty simple, most of the attempts to copy the HKS are done in lower grade stainless and most are made in China. This is a fact. Also, please post all the facts. We upgraded the turbos on Leons twin kit to massive hybrid T28 3040s with larger downpipes and air intake piping. More weight=more stress. He did not brace them and as a result had one crack under the weight. The fact that his EGT's were sky high on that last run also didn't help. The manifolds were glowing red. Greddy manifolds are the worst I've come across, I've seen more of those crack than even the cheapest Ebay copy. Cast steel manifolds are definitely the most reliable, hence the reason why the factory turbo cars are most always done in cast steel. But, they can also be restrictive because the nature of cast manifold construction dictates how many close radius bends you can have and how the collector can be done. Its all dependent on the mold. We've had nice results with the cast manifold in our PHR Street Kits, but only after we spend time hand-porting them to suit. Wrapping does seem to increase cracking at weld joints in the manifolds and downpipes. We believe its because of the enormous heat build up under the wrap, followed by the rapid cooling Nic.

8secSupra Posted November 30, 2006 Share Posted November 30, 2006 Leave him alone, Terry, he's helping me with the Knock Amp I've bought and fitted a BL kit and it had everything I needed in it. I hate 'kits' that don't actually have everything you need... I mention the PHR staged kits because I've heard that it's good quality, it also has everything in it that you need, and I know of a few people getting good results with it. If I had to do it again I'd go for the BL kit again simply because I know exactly what's in it, but if anyone waved a PHR kit at me I certainly wouldn't turn my nose up it. As for the cracking manifold issues, well, I guess some may crack and some may not on each side of the fence, but more stay intact than crack. Perhaps Leon and Dusty aren't the best examples for long term durability -Ian There was no "payback" from the DBB thread intended there mate! Haha Bottom line is, we were the FIRST company in the USA to develop and market a single turbo kit for the Supra MKIV, aside from Greddy and HKS (which are not US companies BTW). So we've had a few years to get it straight. The rest just followed suit. Some people love BL kits, some love PHR kits. Its a debate that will follow for years to come, but in the end, its a very personal decision based on research and budget! Free knock amp coming to you lol....

Wez Posted November 30, 2006 Share Posted November 30, 2006 Did H&S need your car down there to fab a down pipe for you Yes was all made to fit and they did a cracking job too, highly recommend them, had the car for one afternoon if I remember correctly. I drove down with the downpipe and screamer supplied in the kit. Quote Link to comment Share on other sites More sharing options...
Nic Posted November 30, 2006 Share Posted November 30, 2006 he's helping me with the Knock Amp How are you getting on with the knock amp Ian? Did the instructions help at all? Quote Link to comment Share on other sites More sharing options...
Guest Terry S Posted November 30, 2006 Share Posted November 30, 2006 That is funny Jarrett as the worst I have seen is an HKS copy by far. I think I will direct Kean to this rather than trade horror stories with you. Quote Link to comment Share on other sites More sharing options...
Chris Wilson Posted November 30, 2006 Share Posted November 30, 2006 Thats a long way to trailor, but im only looking at my options. I have been told that the Arnout manifold cant really flow enough for a T67 DBB. What are your view on this? I can only understand Garret designations, so have no idea what a T67 is. I would be surprised if the admittedly small port runners of Arnouts manifold posed so much of a restriction as to make it inadvisable to run a big turbo off it, you'd need to measure port pressures on it and compare it with A N Other.

Looks like im going to go for the BL kit, because the quality looks great and it fits within my budget. Both BL and PHR look like great products, but the prices i have been looking at for what i want (67mm) have shown PHR to be considerably more...8secSupra can you give me a price for a stage2 (and stage2+) kit delivered, so i can compare. Thanks Quote Link to comment Share on other sites More sharing options...

Kopite Posted November 30, 2006 Share Posted November 30, 2006 Arnout's manifold is cable of flowing over 800 RWHP, there's a dyno sheet and movie Movie here: http://inductionweb.com/supradyno.mpg Quote Link to comment Share on other sites More sharing options...
mikeyb10supra Posted December 1, 2006 Share Posted December 1, 2006 Arnout's manifold is cable of flowing over 800 RWHP, there's a dyno sheet and movie Movie here: http://inductionweb.com/supradyno.mpg this is the induction motorsport manifold though is'nt it Kop?? quite sure the design is different and ports are also larger Quote Link to comment Share on other sites More sharing options...
