A sneak peek at the new Himni Racing FE RX-8 turbo kit to be released soon. Finally a kit that will fill the voids for in the turbo market for the Renesis guys. Expandable from the base kit for the DIY guys to a 'total solution' package that includes I/C kit, fueling & even a pre-tuned Cobb AP ready to bolt, load & ride. Other perks will include the highest flow downpipe of any other kit to date, lifetime warranty all SS manifold, intelligent & aggressive turbos placement, 'Shot Gun' mounted Tial 44mm WG, Garrett GT35R turbo plus much more. Stay tuned & tell your friends.



Final dyno tuning being completed tonight for the new HR FE RX-8 turbo kit. How's 310 WHP at only 8.4 psi sound with full boost by 3100 RPM? Stay "tuned!"



By popular request, a sneak peak of the new HR FE GT35R Turbo Kit for the 04+ Mazda RX-8. No longer are RX-8 owners stuck with inferior turbo kits using false information to 'trick' buyers into expecting more power than they actually get. We speak real world results only. 310 WHP on an all stock engine (w/ over 100K miles on it) at 8.4 psi & no other mods other than clutch & exhaust. Gone are the days of 'other' kits fooling you into false/high HP numbers by using ported engines, meth injection, higher boost pressures, cold weather tuning, unsafe timing / AFR's, & inferior dynos. We don't just sell products... we sell results.

Q : How much do these kits go for? Is it possible to push higher boost levels with aftermarket parts somewhat reliably? (ie: BHR ignition) ?
A : Pricing hasn't been worked up yet. It will be available as a 'click in build' using a menu. From a base kit that takes care of all the hard stuff (manifold, downpipe, turbo, etc) for the DIY guys to a complete kit ready to go out of the box. Absolutely more boost can be run even without a ignition upgrade. And with a simple DIY coil upgrade, the sky is the limit as long as your block will hold it. (BTW: no reason to buy an over priced coil "kit". A high performance 3 wire coil (positive, negative, ground) can be had for $40-$60 each just about anywhere)

Q : What heatshielding options are there for the OMP and radiator lines?
A : The manifold is made to wiggle around the OPM. With the included Ti exhaust wrap & reflective shielding around the OMP it's self ( also included) the OPM stays happy & unaffected by heat. Water lines are a clean tuck & stay under the turbo vs the ugly over top. Unlike all the other kits, we do this by radically modifying the OEM thermostat housing & it's rad/water inlet & outlet locations. This is the part of the same reason why the kit's dowpipe is the highest flowing of any other.

Q : Is this a twin scroll setup? Also is it a tube header or a log?
A : We were surprised to decide on an undivided manifold. Testing showed zreo gains in performance when we compared a divided design to an undivided. In fact, we noted higher back pressures in the divided manifold that exceeded that of actual boost pressure. This is bad news that has long term negative effects on the engine's exhaust port edges, causing them to super heat & reduce turbo response. In most cases, a divided manifold is superior to undivided. All of our RX-7 manifolds are fully divided tuned design as the engines has an even number (2) of exhaust ports. However, the RX-8 muliti side port exhaust is an odd number (3) and as you know, can not be evenly split into divided (aka twin scroll) turbo. 3 runners from the engine that merg into 1 tube before entering the turbo is not a divided manifold. All 3 simply mix at a different point down the line. Most believe the exhaust pulses to travel in one direction, away from the engine. That is not correct. It pulses back & forth, even in high RPM. With a 3-1 design, all your end up with is 3 runners that still intertwine exhaust gasses & back feed each other at the merge point & only looks 'cool' in a picture. A divided manifold intertwines the gases at the turbine wheel. Until a 3 port divided turbine housing is available, the RX-8 will likely never see a divided manifold.

Q :What tuning solutions are you using, and is the MAF in a 3 inch piping ?
A : That is correct. The MAF is 3.00" T6 aluminum tubing & not the normal 3.50". This is because we are not relying on the OE MAF to meter air but rather a MAP sensor. We are using a Microtech plug & play system for tuning however, it is not the old interceptorX most know of. It is a different system that gets rid of all the old issues that were associated with the interX. However, it was in fact on the right path. Because we aren't tied to the OE MAF anymore, the 3.00" I/C tubing provides increased air velocity over that of the 3.50". Though the 3.50" is nice for the extra volume, it lacked the velocity that the engine really wanted. We tested 3 different tuning options for the 8. (Cobb AP, direct ECU re flash & the Microtech) The Cobb AP had too many tune limitations & limited availability & nothing "real time". A full re flash was great, but costly & required your old ECU to be sent to us & no ability for the customer to adjust tune himself as his needs changed. The Microtech was perfect & took care of all the above issues. It will arrive with a map preloaded & ready to go out of the box. We often say this but it's worth noting again. There are 2 completely different worlds out there... what you read online & reality. There are a lot of people that stand to 'win or loose' based on the "data" they spread across the net, promoting one product that holds all their nest eggs. We have delayed the release of this kit many times in the name of testing & more testing. We also have zero tie to any one product brand & stand to loose nothing by selecting the best tune solution that provides real world results. Careful not to believe the hype you read as the customers best interest can be push aside in favor for their own "bottom line" Also, please note that because we already have so much on our plate with our RX-7's kits/work & that we do NOT outsource our work, that there is a possibility that the RX-8 kit can be delayed even further. We only dove in for the 8 because so many customers asked us to make a kit for the 8 that was backed with the same real results our RX-7 kits yield. Know that we aren't in the RX-8 kit right now to make money. Only doing all the R&D that other kits lacked. I will have someone post the vid while on the dyno that shows the car's boost gauge in a 8.4 psi 3rd gear pull then pans right over to the dyno graph on the monitor showing that 310+ HP run.

If you have any other questions, please just let us know

 

Another top mount, yay.

 

I don't know if you're being sarcastic, but a little competition and variety is the best thing that can happen to the rotary.

 

Yep, another non-track capable kit

 

If you say so. The pics are shitty but it looks like a tuning nightmare from what I can see.

 

it looks like the maf is in a 3" housing.

I do like the inferior turbo kits comment in the beginning

 

Sub'd.. We'll See how this kit will compare to the other kits

 

Yeah if that piping is not exactly the same size as the OEM pipe there will be issues. But it does look like a nice straight path of pipe to the MAF so that is good.

 

I'm curious to know how they're doing Cobb tuning...

 

despite what everyone thinks, you can tune with a cobb on a blow-through system.






.... its just harder

 

Yeah a properly setup blow thru system is very possible.

 

Why?

 

heat plays a large roll in his assumption, im assuming

 

My question had more to do with licensing rather than any potential technical issues.

 

im sure they wont be a licensed tuner for Cobb

 

The RX-8 already struggles with cooling as it is. It's nearly impossible to track these cars with a front mount intercooler without overheating within 5-10 minutes in normal weather. Since the turbo sits up top, a top mount intercooler is out of the question so that's that.

Also I know the OMP is shielded, but for sustained high load high heat use the heat shielding can only protect it for so long.

 

Yeah I never liked the idea of having exhaust temps in the 1700F range anywhere near a $1,000.00 OMP. Unless they relocate it which is even worse IMO.

 

So now we're on to brass tax.

How can they have a magical base map that "just works" out of the box?

And what happens when Cobb drops RX8 support for Race?

We all know its coming... just a question of when.

 

Maybe they are working with Jeff...

 

that is the same thing I asked, Shell

 

Great to see another company enter the market. Hopefully they are a good vendor with good support because the last thing the 8 market needs is crappy products and service.

 

Amen to that, but only time will tell.

 

Completely agree guys... and I don't mean to crap in their thread..
Just have some questions that I'm sure will be answered in due time.

 

Himni Racing sent me a FB friend invite a long time ago. I just accepted so I can follow their progress on the kit.

 

I see no issue tuning this if you use a MAP based system
