I do find myself sitting there listening to the idle and losing track of time :lol:

OK, so it's not as powerful as a normal full bridge (by a tiny margin) but... I'd still do it again for the noise.

Also, talking to some people about the potential of a long tube header to hopefully pull more through it through scavenging...

Dan my buddy Paul ( Tyler 82) has a BHR long tube header on his car and it made little or no difference to the actual BHP. I think RR said he gained maybe ONE HP.... ONE!!

It cost him almost 3500 yoyos and for what he gained it must be the worst bang for buck mod ever. Don't get me wrong the noise is like nothing I've ever heard. The closest thing I can equate it to is the 787 and that's saying something.

He has a RB mani mated to the BHR LT header and topped off with a RB cat back. You can check it out on his project build to see it. Search Tyler and you'll get it.

Would I pay that kind of dinero? Not a hope in hell. If you can get something a hell of a lot cheaper then by all means go for it otherwise personally I'd run a mile

I think there was a few slight design flaws that Carl @RRP figured out with the BHR long tube which meant it would offer better gains which he is/was in testing with. If I recall, something about the main flange and the collector in particular.

Speaking of which, recent post about the manifold flange he's had done. Post should be some where in his trader section.

On a standard/ normal full bridge perhaps, but the thinking (from Josh up at RR) is that the race extension porting lines itself up for (potentially) good gains through a long tube header. The reason being that the amount of overlap between intake and exhaust on mine is massive - hence the braps. More overlap should in theory mean more potential for scavenging. I'm not about to spunk megabux on it, as it would also need to be mated to something decent in the middle and so forth, but the theory is there.

EDIT: Also, how can he have the long tube header mated to an RB mani? The header replaces the mani does it not?

LOl yeah you are correct Dan, the header does indeed replace the mani,my bad :roll: #-o

Interesting stuff from Josh,if you do proceed with a LTH you'll have a car that sounds incredible.I wish Paul had a vid up on his PT but trust me I was behind him most of the way back from RR to the ferry in Holyhead and it was a treat for not only the ears but also the eyes.

Two straight lines of flames almost tickling my bumper at what seemed like every other gear change,simply awesome.I was like a kid giggling my loaf off most of the way to Wales,epic!! :twisted:

Post by Dr. FrankenRex » Mon Jan 21, 2019 3:38 pm

Not gonna lie, mine does that already with the race extension. My main concern about going LTH is that I would be causing some issues for noise tests as I do want to put the car to good work on track. If it can't do that then unfortunately the exhaust setup would need to change.

Already concerned about Castle Combe in just over a month...

It is worrying me that I may need to go after something a little more subdued like the Racing Beat, or RRPs active system - which would be a shame. (not that Carl's system isn't a good piece of kit, just that I absolutely love the Pettit system's look and sound).

Controversial statement, but surely a long tube header needs to be tuned to the engine specifics? lol

It does look awesome, though. If your engine wasn't all peripheral ported and such then I'd ask to borrow them :D

Bit early for porn Daniel!! :lol: It does look fantastic doesn't it? I saw it up close and personal on Paul's car when she was up in the air at RR and it looked the business 8) If memory serves me RR had a spot of bother with the welds though,i think they were causing some fitment issues but they sorted it.

If you did get it head for the " ring " your car would sound incredible at that circuit...

I do believe the BHR long tube fouls on the front subframe and needs the subframe pinch weld grinding down and tacking back together again. Although that instance in the states might have been down to other factors.

I did see this on the RX8club post involving an R3 - whether it applies to the S1 as well I don't know.

The O2 sensor also fouled on the gearbox as well.

Wanna buy mine? Full LTH system, including cat. Too noisy for road / track at the moment, but it wouldn't be if you fitted a rear silencer of some sort.....

In contrast to most (or, in fact, all so far...) it actually works. 203bhp on standard ports. And fits. And might even pass emissions. I know cos I designed it, and RR tested it. I'm genuinely interested to see if my exhaust on a properly ported engine would set the NA record. :twisted:

It won't fit my 20B, unfortunately. :(

I ain't gonna give it away though. If you want a proven LTH full system, designed by an F1 engineer then it will cost you big :money:

(I'll even throw in the straight-through rear pipe that makes it sound exactly like a full-bore 787B :!: )

I know you're close with both RR and Alex at CT. Isn't alarming that they got more power and torque from just a streetported rebuild with only a catback upgrade than your R3 with FB plus the extra new porting, full front to back exhaust upgrade (including decat), new uprated RRP coils, ram air duct and uprated panel filter?

I've been honest from the outset, and still am now, that I am disappointed in the headline power figure I'm sat with. Funnily enough Josh and I were chatting last night about the differences in the torque curves between my engine and Alex's.

A couple of things are worth noting - had I gone for a 'standard' full bridge port I would be looking at more power as it currently stands. RR's full bridge record sits about 215whp. Not huge amounts more than a streetport, but a good 10% differential.

With experimental porting like mine, you can't hope to predict the output; likewise with such radical changes in the engine's characteristics (port timing, port overlap and so on) it is likely that the careful design process Mazda went to with regards to the intake length, exhaust sizing and shape and other factors may now not be perfectly matched to my engine - this is the part of the process I'm going through with Josh and with RR.

Ultimately, whilst I won't discuss costs directly, it didn't cost me a great deal more to go for this than a full bridgeport build. Whilst I'm down on power, my engine revs much more freely than a streetport, or even a bridge. It also has a unique-ness which cannot be matched by anything else on the roads at this point in time (excluding Josh's own car) - when modifying a car never discount the rare-factor, afterall. To have something that is unique and personal is why most of us do it.

As of this morning I have engaged with some fabricator friends of mine and we're going to try and make a long tube system designed specifically for the porting my car has, along with a custom catback system that will keep things at a tolerable noise level for the track.

When all is said and done, I didn't get this porting done solely for power - I enjoy being a the cutting edge of development and that comes with its risks, both good and bad. Do I wish I had more power? Yes. Would I do it differently if I was getting it rebuilt now? No.

Also, with the porting the way it is, it actually lends itself really nicely to forced induction without any of the usual drawbacks for a renesis engine. Although that's for the future :thumleft:

EDIT: Whilst this seems like nit-picking, it is important to point out that Alex's car does have a decat pipe as well :thumleft: For clarity I am also running a stock panel filter :)

I know you're close with both RR and Alex at CT. Isn't alarming that they got more power and torque from just a streetported rebuild with only a catback upgrade than your R3 with FB plus the extra new porting, full front to back exhaust upgrade (including decat), new uprated RRP coils, ram air duct and uprated panel filter?
I've been honest from the outset, and still am now, that I am disappointed in the headline power figure I'm sat with. Funnily enough Josh and I were chatting last night about the differences in the torque curves between my engine and Alex's.

A couple of things are worth noting - had I gone for a 'standard' full bridge port I would be looking at more power as it currently stands. RR's full bridge record sits about 215whp. Not huge amounts more than a streetport, but a good 10% differential.

With experimental porting like mine, you can't hope to predict the output; likewise with such radical changes in the engine's characteristics (port timing, port overlap and so on) it is likely that the careful design process Mazda went to with regards to the intake length, exhaust sizing and shape and other factors may now not be perfectly matched to my engine - this is the part of the process I'm going through with Josh and with RR.

Ultimately, whilst I won't discuss costs directly, it didn't cost me a great deal more to go for this than a full bridgeport build. Whilst I'm down on power, my engine revs much more freely than a streetport, or even a bridge. It also has a unique-ness which cannot be matched by anything else on the roads at this point in time (excluding Josh's own car) - when modifying a car never discount the rare-factor, afterall. To have something that is unique and personal is why most of us do it.

As of this morning I have engaged with some fabricator friends of mine and we're going to try and make a long tube system designed specifically for the porting my car has, along with a custom catback system that will keep things at a tolerable noise level for the track.

When all is said and done, I didn't get this porting done solely for power - I enjoy being a the cutting edge of development and that comes with its risks, both good and bad. Do I wish I had more power? Yes. Would I do it differently if I was getting it rebuilt now? No.

Also, with the porting the way it is, it actually lends itself really nicely to forced induction without any of the usual drawbacks for a renesis engine. Although that's for the future :thumleft:

EDIT: Whilst this seems like nit-picking, it is important to point out that Alex's car does have a decat pipe as well :thumleft: For clarity I am also running a stock panel filter :)
Massive hats off to you for taking such a leap of faith. I agree that risks need to be taken to make advancements. Just a shame when they don’t pay off... but as you say, if you’re continuing down the rabbit hole, hopefully with more modifications (and unfortunately more money :( ) you will make some big leaps forward, any excuse to go forced induction ;)

I think you’re absolutely right about having something that no one else has. Even just a unique sound, like you said, if something to be thrilled about. Rx8s are all about the experience as we all know, not headline figures.

I hope I’m not coming across as trying to ruffle feathers. Im not. I'm enjoying following your build as well as the CT series. Just wanted to open a chat about it.

Looking forward to seeing more!

Not at all, I don't offend easily :D

The thing that a lot of people are overlooking is that 191whp is still a decent amount for an RX8 to make and it does drive very nicely indeed
