it's (almost) 2015: Gentlemen, start your turbos

nothing makes our motors run like turbos and 2015 promises to be by miles the most exciting year ever due to the loads of new turbo options.

due to aero advancements we may have to re-think sizing and power levels.

as you know generally we associate 62 mm inducer compressors w around 400/460 ROTARY (diff than piston) hp...

maybe a 62 will make 600 in 2015!

the mid range turbos, 64 mm inducer, were generally good for 500/550... in 2015 more like 700

perhaps re-thinking sizing is in order.

there are some fascinating match-ups:

in the 62 category we have:

Borg Warner

S300 62 FMW... a carry over but sports a billet compressor and really nice turbine wheel. 6.527 cold side area.

S300 SXE 62 new engineering for 2015 both cover and wheel take flow to a new level. improved journal bearings. good value for high tech. avail March 6.54 area.

EFR 8374 a hair larger compressor w advanced aero but the 40% lighter turbine wheel is the key. should move boost curve left. 6.626 area

Garrett

the GTX3582r is pretty much everywhere plus 10% to the regular GT35. whether it can get to these regions is still open for speculation as the turbo has a small turbine wheel. 6.519

Precision Turbo

new for 2015 is the GEN2 62 turbo. sporting a 52 trim along w dual ceramic BB it should spool now and is rated at 800 piston hp (80 pounds per minute) or 615 rotary. cold wheel area 6.91


properly supported and tuned the 62 sized turbos should be able to please most of the rotary market.



moving on to what was previously the "mid-sized" 64 category.... (500/550) 7 inch comp wheel area.

Borg Warner

S300 SXE 64 new engineering for 2015 both cover and wheel take flow to a new level. improved journal bearings. good value for high tech. avail March 7.178 area.

Garrett

GTX4088r sports a 65 mm inducer and map showing 83 pounds of air. has a large for Garrett turbine. 7.167 comp.

GTW3884r (the new "W" designation is for "wide" as in compressor map. wide is good) rated 100 hp more than the GTX4088r... no info as yet on Garrett site.

both interesting turbos...

Precision Turbo

new for 2015 is the GEN2 64. rated at 900 piston/700 rotary. dual ceramic BB 7.07


as we get into the 8 inch area there are additional very interesting turbos but you'd better have a different transmission and be able to keep the car on the ground...

BW S300 SXE 66 and 69
BW EFR 9180

Precision GEN2 68

2015 should be an amazing year!

Very interesting stuff. I was dead set on going to the EFR9180 this summer but depending on the price point of the BW S300 SXE 66 I am not sure it is worth it for a pure street car.

Hmmm, HC's posts always bring out strong points of view. Usually find his posts very informative and interesting. As the previous poster found after five years all good things take time.

2015 will be a different year for turbos for sure as I think 2014 has proven the BW EFR turbos are more than hype on a rotary application.

My dream 2015 turbo set up would be twin sequential EFR 7163 IWG v-band turbos on my FD.

My EFR 7670 FC taught me rotaries can make incredible low rpm torque with the EFR turbos and sequential twins will uncork the rotary top end potential the little 420rwhp/420rwtq EFR 7670 couldn't.

I am also exited to see how well the mixed Axial/Radial flow exhaust wheel works on the rotary- my experience is it will be spool-a-licious.

Price of gas is down, the turbos are better than ever- lets burn some gas and kick some piston *** in 2015.

I personally am interested in this thread topic. I am in the market for a single turbo kit in the near future and would like to know more about these new turbos. I also like the way Howard presents the information, it saves me time from going back and forth between other sites etc.

I am not however blindly following any suggestions of his or any other members on this forum for that matter. If I were, that would be my fault and no one else's. So give it a rest and let's get back to the point of this thread.

I feel like this forum is full of woman bitching at one another lately.

I think the most important thing we have learned from Howard's journey in the past few years is how hard it can be to build a high hp car. He has shared both the good and the bad, and i think that is worthy of some respect. we do not often get to see the hurdles and pitfalls, it is usually swept under the rug.

i respect Howard for sharing that, he's also been friendly the few times we've corresponded.

i do not always agree with the conclusions he draws from a given set of data, but i don't really see why that is even unusual. i really don't see why posting a compressor map makes everyone so angry, its just a map, you're free to do your own calculations....

and you may want to ask fendamonkey just how often his car has been broken last 3 years?
.. or if he has yet grasped why the return line on a bypass fuel system needs to be as large as the max lift in the reg , or at least setup with a two speed control circuit ?


it would be much better if other forums had some sort of accrued points system to weed out the serial trolling there
much like these guys had 5 fuckups each before total bans where enabled


and just FYI if you question my background ... 20 years ago
i was running what would have been the worlds first 6p weber manifold
.. hand customed .. with a wray supercharger,, with urea/ water injection

all hand built by myself

.. and in that year i carried out the first - out of state- ( WA ) install of a microtech ecu .. d4s
( Doms own words )
just one of just many varied ecu installs and custom manifolds or custom LPG setups i have made since

i also had to laugh
,, cause i have an engine half built here,, for a guy 300 miles away in albany
( actually 270 miles , i exaggerated a little )
i suppose angryperson is not aware there is 4200 km between perth and sydney... and i get asked all the time

sydney is also just a bit closer than the grass drag setup i helped evolve 16000 km ( 10 000 miles ) away

...and i am yet to work out how far lithuania is ...

as for calibration
20 years ago i was installing , crap shooting , calibrating and commissioning PLC and DCS and watchdog systems
for zone 1 class 1 ( explosive, asphyxiating ) hydrogen reduction plant worth $100 000 000 ( then )
( closed loop cascading tunes and purged water instrument calibrations )


i dont have to make this stuff up
there is plenty of posts and pictures of my stuff all over the net
some of it up that long imageshack has pulled the hostings

//

T-von, thanks for the support. i saw it how you saw it


anyone wanting to contribute is welcome
any one wanting to dispute is also welcome, as long as it is on topic, not aggressive , is not slander and libel
and not from people with an established loaded agenda warned previously for taking it too far

i also got a few supporting emails from the last thread when i tried to shut the same trolling lynch gang down there too
many people are just over it,, if they wanted to see character assassinations, they would have logged on to RCC

//

chibikougan.. im sorry i didnt realise you was a minor ..

it is clear to most that you intend to be a nuisance here

but i will spell it out for you.. get on topic

if you dislike swearing to much,, there is a report button ...give the area mod something to do
i do not have the power to modify or delete anything posted here
but
i ( and any other mod ) do have the power to add infraction to anyone breaking the rules, anywhere
disrepecting a moderator has some of the highest penalties

,, disrespecting a direct instruction from a mod also gives me the ability to escalate things to a custom level

angryperson found that out when he was initially given an infraction

but chose to escalate with some crack rage emails

whence he received two further custom infractions ( one each mail )
and so went out of his way to initiate his own perma-ban

i have posted just one of his rages verbatim ( his swearing , not mine )
as it is an example of just how unstable and much agenda he was holding for howard, and anyone in his path

personally .. if i had my car booked at a shop 300 miles away
,, i would be double checking the name on the emails , and cancelling

//

i could have gone further with the points thing for some other users
..and i still will if i have too ...

i dont whack my stick much,, but when i do,, it is a hard stick ..

i expect the incident is going to have a few mods looking long and hard at what happened, but i will stand by what i have done
these guys got plenty of warning,, and many people took offence to the thread trolling
several moderators where here before me
,, and chose to stay quiet on the obvious lynching
and also the attacks and threats by a mod to some readers.. who.. like me ...raised objection to the schoolyard bully behavior

i am not sure if they are too scared to squash this behavior
- no matter who instigates it -
of if they intended to leave these two offenders for me to catch and burn

i expect it to be discussed within the moderation forum as to thrash out a minimum code of behavior for dissenters,, and for moderation staff

// to howard,, i must apologize that this sort of behavior was allowed to go on so long
i personally believe your information doesnt break any rules regards to advertising
- after all you are a payed vendor -
and yet you still neglect links to your business in any post, or sig
and certainly are less obvious and more open in your "infomercials" than other traders
,, whom no one has made any objections to ,, namely turblown and banzai
( no offense intended , i believe as payed vendors, this is entirely your right )
please continue , as i think if anything has leaped bounds for rotary owners in the last 2 years , it is in turbo choices , and your opinion is valid and welcome

// currently i am fighting a very poor internet connection
and it is a struggle to post
but rest assured i will be back to crack heads if you give yourself enough rope

More perfect examples of the excellent moderation. I don't care what you do all I asked was the removal of YOUR vulgarities. Now you are attacking and insulting me? I will be taking this up with IB staff.

Thanks for showing the true face of moderation of this board. If you think I care about being banned you give yourself to much credit. I don't care I am on every other rotary board. I just thought I would bring up the actual crux of the issue the terrible moderation. Thanks for being a perfect example of why this board loses more and more people.


I like how you are to busy to edit a few words but free enough to type up a 3pager on stroking your own ego attacking me and fender who cannot even defend himself. Should I post the thread where you come in after all is resolved and pick a fight for those infractions you posted?

Makes a lot of sense.


Oh and I said Turbo so it's on topic.



Hmmm....

Dunno why he doesn't come online anymore, maybe it's because all his deceiving lies and con artistry has been uncovered and nobody in Perth trusts him anymore.

in which they where repeatedly warned before served infractions for EXACTLY the behavior you have seen in this thread

since they chose to continue this thread as if it was the other

i see no reason not to continue my warning to ban them for that behavior

if you look a fendamonkeys #15 post here, you can see the bait

the discussion is not about howards car
or the other thread that had only one factual post a page
- primarily because it was filled with posts from trolls with agendas


but about new turbos for 2015

already their has been many independent voices in this thread
yelling out for the trolls to shut the **** up
as they are interested in what relative information howard .. or anyone else .. has to post on the matter


anyone with anything constructive to add on the subject
is welcome to have there say

anyone undermining and belittling anyone or any authority
can bugger off to the other forum, already filled with such hate


A couple of those should be your infractions as you came in that thread 30 days later and picked the fight....

If people would act civilly we would not need moderators.... (or police for that matter)

When corrected we feel badly about our behavior and then attack authority.

What a thankless job being a moderator is... wouldn't everyone rather pay the unruly adolescent?

Here is an Indian Parable to start our new year.

Peace,
Barry Bordes

An old Cherokee chief was teaching his grandson about life...

"A fight is going on inside me," he said to the boy.
"It is a terrible fight and it is between two wolves.

"One is evil - he is anger, envy, sorrow, regret, greed, arrogance, self-pity, guilt, resentment, inferiority, lies, false pride, superiority, self-doubt, and ego.

"The other is good - he is joy, peace, love, hope, serenity, humility, kindness, benevolence, empathy, generosity, truth, compassion, and faith.

"This same fight is going on inside you - and inside every other person, too."

The grandson thought about it for a minute and then asked his grandfather,
"Which wolf will win?"

The old chief simply replied,
"The one you feed."

It must be a thankless job being a moderator, you did what you had to do, and its a shame these tools had to keep going. i'm going to miss some of them.

I've got the feeling you would have had me banned from the Aus forum if you had your way and i would have deserved it, still a lot of the most entertaining and sometimes intelligent (i use the term loosely) have been banned from all the forums and its a shame, but thats how it goes.

Its also a shame HC doesnt defend himself, but also quite noble. I appreciate his mathematics and numbers, they are a handy reference, at the same time I agree with his detractors, except there was no reason for the contempt and disrespect they displayed, and just kept going with.

Anyways here is something I think applies to this forum, the other forums, all involved, in this thread and indeed every person who has an arsehole, but i dedicate it to the banned and owned;

Bumpstart is extremely knowledgable, is on many forums, and has helped myself and others on extremely difficult situations.

If you have a problem with ccurse words then go away. Until you've proven a track record of helping others and demonstrated credibility, you don't hold any weight in this argument.

My EFR 7670 FC taught me rotaries can make incredible low rpm torque with the EFR turbos and sequential twins will uncork the rotary top end potential the little 420rwhp/420rwtq EFR 7670 couldn't.

I am also exited to see how well the mixed Axial/Radial flow exhaust wheel works on the rotary- my experience is it will be spool-a-licious.

Price of gas is down, the turbos are better than ever- lets burn some gas and kick some piston *** in 2015.
Wait how would we set these up in sequential?

thanks

I was thinking pretty much like Mazda did without the shared exhaust outlet.
