The Turblown Turbo System Differences
 

For those that don't know, a few pictures might help :)

1st and foremost is the turbo manifold; Log style vs our tubular merge collected unit. A lot faster spool up, and more power everywhere, especially in the high rpms, even at low boost pressures. Right angle bends like pictured are terrible for flow, we also don't cheat the entrance to the turbo which basically mimics a on-center turbine housing( We've 600rpm difference in spool time from just swapping tan-gentile to an on-center turbine housing).

2nd is the Hardlines, pretty staight forward. You don't have to worry about anything cooking here. Other kits have lines physically touching 1700+ F degree parts. We hardline both the radiator lines, heater core lines, and turbo cooling lines. Even the oil drain return is very close to the turbo manifold. If any of these lines break you're engine will be toast before you realize what is happening.

3rd we use Garrett Intercooler Cores, and Tial Wastegates/Bovs, no knock offs or ebay parts. Garrett cores produce lower air temps, proven fact. The colder the air, the higher your air density. Air density is the key to power. We can also tuck the intercooler farther back if you live in CA or just want to be stealth. We also don't use any 90 degree couplers, all connections are straight connections which if setup correctly won't blow off.

4th we use a flex connection at the end of our downpipe, and no two piece vband connections which always leak. We can also install as many o2 or egt bungs as you like in both the downpipe and turbo manifold.

5th we hand fit everything on a chassis in house, this ensure the best possible fitment. Nothing is made from Jigs alone.

6th Our turbo system works great with any Mass Air flow sensor based ECU like the CObb AP, and its setup draw through just like OEM. We have since changed our intake track and it works flawlessly. We also use a bosch style recirc blow off valve that is necessary for a MAF setup. We also install an o2 bung in the turbo manifold for the necessary quicker response when using the Cobb's o2 feedback system.

7th All the turbos we sell are water cooled, we don't use oil coolant only turbos on rotaries. Garrett says the turbo will last 30% longer with just adding water cooling. From years of experience rebuilding turbos, I completely agree. We can also put on whatever turbo you want, do you want just a quick spooling 300rwhp? Choose a GT3076R, or do you want 550+rwhp? We can do up to a Gt42R frame.

8th We are always pushing the envelope, making each system better than the previous. We are also now able to turbo the S2 cars properly( no check engine lights, everything works like OEM(dash, etc etc)). And once again we hold the known* record for highest RWHP Rx-8s( using the OEM Rotary engine).

Will update with more photos..

Turblown Rocks. That is all.

I do like the "*" after known, however. lol

Now we just need to see some of the S2 owners head over to the deep end of pool and hangout with the cool kids :cool:

"Due to fitment constraints of the RX-8 chassis, this turbo system requires premixing of injected fuel with two stroke oil as well as relocation of the battery. In addition we highly recommend a Cobb AccessPORT ECU upgrade with a custom MazdaManiac calibration. "

is that due to the OMP?

Yes the OMP is just too close to the 1700 degree turbo manifold. If you look at the 2nd photo attached above, the OMP in one of our competitors turbo kits is actually touching the turbo manifold. Great recipe for disaster see as its a $1500+ unit to replace, not to mention it you will probably have to take over half the turbo kit off just to get to it.

If you really cannot live with doing premix I can make a turbo manifold to fit, however you will have to purchase a heatshield for the OMP($199 extra).
Turbo might spool a tick slower also as I will have to put more bends into the manifold.

9th E-X-C-E-L-L-E-N-T customer service/satisfaction... ;)

there swimsuits don't have any pockets, let alone deep ones


fixed, people need to wake up and realize they are not stuck with only one take it or leave it choice. I'm glad 9k had enough sense to seek Kane out for his build ... :)

Ooooh totally doing this next year ..... Stay tuned, Elliot :D

Would it be an idea to locate OMP somewhere else, and let it sip from a external reservoir?

Sounds very plausible if someone wanted to do the custom work( SS OMP lines, adapter etc). This would be the best solution.

Hummm. Hey what is the life span for a built motor with one of these setups being that it is tuned correctly.

it seems to me it would make more sense to make a new engine mount that will allow the OMP to stay in place with a shield yet also allow the manifold to fit through there too. There seems to be plenty of room except the OE mount was not built in mind with multiple exhaust tubes passing through there in the forward direction.

When are you going to offer the ultimate mid-mount setup?

Thats a good point when i had mounted the race roots driver engine mount it opened up a lot of room on the side which i liked so much, but it just wasn't so user friendly for the driver side for what i had going on.

Hard to say as high mileage @ 400+rwhp hasn't been done yet.
I do however have 60,000 miles on a single turbo FD engine I built 9 years ago :cool:

I have seen lower rwhp turbo Rx-8 engines last 30K+ miles, so I am sure it can be done.

Hows your car running?

As soon as someone wants to pay for it, or I have some free time. Doubt I will have any free time soon.

Another shot of a recently completed turbo system.. Starting another one soon...

I like what you did there with the intercooler pipes

I agree with previous posts about the OMP, you need to provide a relocation kit to appeal to more people. Less guess work for the shop or person installing it.

i like the details --such as a true cai for the turbo, hard lines etc. Very nice.
Add Steve Kan to the tuning options.

Thanks, I still think a mid-mount turbo with v-mount radiator/intercooler is the way to go even if it means notching and reinforcing the chassis rail to fit, but it is probably more custom than most people will want to engage in. Now that I'm working again it is back on the wish list for a future build in the Street Modified race class ...

It doesn't require any modification to fit the larger turbo that Turblown is using in the low-mount position. It is just a tricky fabrication job to create the manifold and downpipe.

The other possible mounting position would be about where the stock air pump is located.

well I didn't think anyone was using the air pump much for these installs, and the SM class allows full removal of the emissions equipment

I have some ideas of my own on how to do it effectively, which is more important to me than just making do with a predefined space

Quick question. What's the mid mount you guys are talking about? I know the low mount and top mount but never heard mid.

I like what everyone is doing on rx8 development. I just don't see spending 10k on 300-350 whp and still might not be reliable enough for me. Gotta pay to play of course. Ive been reading and thinking what route to go.

Think they are actually talking about low mounts - off the manifold .
Technically you could say :

Top mount - obvious
Low mount - off the manifold
Mid mount - next to the gearbox
Rear Mount - where the rear muffler is .

I always used "mid-mount" to mean a location that is near the LIM.

Locating a turbo at the CAT position or at the back of the car are both "rear-mount" applications.

I meant next to the engine with the shortest most direct exhaust piping, whatever you want to call it

The v mount minimizes IC piping length between the turbo and the TB and also allows uninhibited flow to both it and the radiator while also allowing direct easy intake piping to the compressor and airflow to the filter. It would require completely reconfiguring the radiator setup and also cutting a big hole in the hood with duct (GT40 style) for the IC to exhaust out.

It would roughly duplicate an FD3 setup a racing friend built on his SSM class race car. The SSM class is for 2-seat sports cars like the FD3 and SM is for 4-seat sedans which is where the RX-8 is classed. His divided manifold/turbo setup us making impressive power and torque at low rpm, almost too much. After studying his car it should be possible on the RX8 but our chassis doesnt have as much space between the engine and chassis as the FD3 has and again the RH engine mount bracket would need a complete redesign. I had some pics of it but can't find them.

Can someone say 400+rwhp low mount? Hmmmmmm turbos...


You can keep your OMP !

^ That's what I'm talking about. Details please.

Uh, like this:
http://www.mazdamaniac.com/images/misc/v_mount.jpg

The piping is even shorter than in your example and doesn't require that the rad be moved at all. IC outlet temps are 15°F over ambient in boost.

Looks familiar!

WTF? Why can't I edit my own posts so I can fix quotes like the mistake above?

^ Does all that fit without modifying the sheet metal around the turbo MM?

Both setups fit without modifying the sheet metal..

So thats what your setup looks like.. Now post the dyno sheet :)

I thought you said it was a P trim? That looks like a T31 housing to me...?

not like that, sorry

What turbo is that on your manifold? Is the manifold/DP/turbo package available for purchase?

OK, explain?

@9krpmrx8

Straight Garrett T3 BB GT35R. I am playing around with different sizes, packages etc. I am currently working on a Tial 1.03 version, and a Comp turbo oil-less system.

Obviously this requires a completely new motor mount bracket.

Not sure exactly on pricing yet, but I am figuring $2000~ish for the manifold, down-pipe and motor mount..

what's to explain, you have your view and I have mine

more power to you, it's just not the way I would do it

do you have anything that demonstrates fitment on the engine or in the chassis?

I know somebody will ask

http://www.compturbo.com/spotlights/oil_less

I'm trying to understand your view since both systems are functionally identical, with the exception of mine having shorter piping.
The ICs are similar in size (though mine doesn't require the air to make a turn in the end tanks), the cooling airflow is identical, the piping on my example has fewer cuts/bends and the bends it does have are more gentle.
The inlet piping is nearly identical in length and the exhaust path is similar.

in your mind, maybe ...

Soon! Got a bunch of new stuff happening over the next few weeks. I'm not gonna be able to post in your sub-forum soon, so I'm getting it out of my system. lol

It is the Elliot turbo, according to Scott and Mike! lol

Man id be interested in that Low mount manifold!!! I currently have a greddy kit with the 3071R, and debating going top mount or just building a V mount intercooler set up similar to MM.. hopefully ill start working on it during the summer when i get me a welder, and move into my new place. that manifold looks real nice.

Dude. Cut the crap, forget your blind, enraged hatred of all things me and have an intelligent conversation for a second.

Please?

We all have plenty to learn and I am just not seeing where the two examples are divergent, except for the mid-mount turbo in the FD vs. the low-mount in the RX-8 and the latter's smooth flow-path.

Amen, I thought your set up was great! Some people just cant get above hatred sometimes.

Not at all. I haven't said anything negative about you or what you are doing, just that I have a different idea.

You are making a comparison like you have a pic of a system built by me, all you have is a pic of an FD3 showing something similar to what I would like to do. You are making assumptions about something you haven't seen. In fact, it doesn't yet exist.

I have nothing to show, hence nothing to discuss. It's that simple. You are the one pressing me, not the other way around.

Just because I think you are a terrible excuse for doing business with as a vendor has nothing to do with how I perceive you as individual. This is just more schizoid paranoia no different than you attempting to harass and intimidate me via text the other evening.

so yeah, please ...

You provided the example. What would you change?

Clearly inseparable, based on your actions.

Uh, whut?

Do this and have it ready by the time I destroy this AMR turbo :lol: I'm not interested in a top mount, I love this idea though.


Oil-less turbo = awesome. I don't even want to know the price of one of those :lol:
