Defined Autoworks 523whp 35r!!

[FDwarrior]

Ok, where to start? I went to the dyno two weeks ago to tune my car for an autocross. I had no number's in mind for making power, I just wanted a tune. Logan at Defined Autoworks built and tuned this car, here is what happened. We did many pulls with these numbers and checked the dyno, its a dynapak as well. We also only had 93 in the car it has been running 93 since. I had a dirty k&N on the car, the whole time (4in). I also had 2 year old plugs in the car from my work bench. No nos, no tricks just whats here.

Here is the car, a rotary powered s14 beast



peak power ( you can see the spike to 16 pounds then it holds 14 pounds to redline)



peak torque




We were stunned, I don't think there has been a 2 rotor with just a half bridge and regular old 35r make this power. I will provide more detailed specs further down. The 35r is just a dual bb precision, NOT a billet wheel.

Here are the engine specs

13b-rew block and irons
13b-re port runners
D.A circuit port on the primaries
D.A half bridge on secondaries
D.A turbo exhaust port
Fd 9.0:1 rotors, balanced and clearanced.
3mm Apex seals
solid corner seals
New FC rotor housings
Coolant jacket modifications
race rotor bearings
high pressure oil reg
FC front cover
13b-re intake manifold

Turbo

1.00 divided turbine
p-trim wheel, standard wheel
.70 compressor housing

Electromotive Tec GT
Inductive coils
S4 Fc waterpump
Racing beat front pulley
Mazda comp waterpump pulley

Engine bay

Engine bay pics. The engine placement is excellent in the chassis. The front of the engine is even with the shock towers. The top of the block is about half way up on the towers. The intake is pretty tall so it looks like the engine sits high. The engine was initially designed to use a dry sump system, so the bottom of the block basically sits on the subframe. The subframe was modified and a custom oil pan was built by defined instead of using a dry sump. The placement of the engine did not have to move due to subframe modification. Everything was built by defined. The car was at Gordon's meet two years ago.

Im bad at taking pics, but you get the idea.











We are going to go back with race gas and play with the timing, the timing is conservative. I will update the thread with the new results.

Good numbers for a pump gas tune.

To my knowledge no one has ever made these numbers on a regular 35r, with a 2 rotor. I can't wait to see what it does on race gas with more aggressive timing, along with good plugs.

I know a bloke who makes (are you sitting down!) 535rwhp through tires (not hubs) on a dyno dynamics (see my site where I talk about this and show details *not just internet BS comments*). This is on a regular GT35R and a street port!

Not everyone posts their shit on the net so you or others dont know about it

The dynapack reads allot lower than a dyno dynamics, I went from one to the other on the same day and there was over 30rwkw or 40+rwhp loss, this is mostly due to the slip rate of the tire which you are not dealing with when you take them off and bolt directly to the hubs.

BTW your car is awesome, not a worlds first for a 35r on a 2 rotor but its something to be very proud of

I think that's awesome. Im not some one who hates on some one else's success. I love the fact that some people are still able to innovate and rewrite the rules on regular convention. Im not done though, we still have allot more power to make by just messing with the timing, and playing with the waste gate. The 523 was just what the car made on our baseline. I had Logan smooth out the tune so I could auto cross it that weekend. I also want to make an exhaust manifold. The manifold on it is just a mass produced china mani. I have inconel that Im going to use. I will also get the sheet for the tcf values. The dyno we use is packed most of the time. When we get another session, I will update the thread.

I also rarely post anything about my cars on the net. I decided to post this to promote business for Defined Autoworks. As you can probably tell Im terrible at making big posts.

Here is a burn-out vid. We were bored, in the middle of hick town usa, and one car a day goes down this road if your lucky. It's not much of a burnout but you can hear the spark cut only rev limiter.

I heard of sr swaps into 7's but never rotary into s chassis cars. SO sick. Great numbers too.

[RICE RACING]

What boost pressure?
can you please post the sheet that lists the TCF value

Very nice set up, seen you post this on RX7club, pitty those idiots have no idea about rotaries or cars (rx72c = dumbarse of the decade!)

[TitaniumTT]

Indeed! I love how most people are looking for 400rwhp out of a 35R thinking it's the best you can do. Just like "350 is the highest you'll get out of twins @ 15psi"

It's amazing what these things can do when they're in the hands of someone who know's what they're doing :cough-you watching BDC, HC, rx7cwhatever your name is:

GT35r's are very capable turbos, a few friends of mine use them. A totally different animal, but we made 601 awhp on a stock bottom end 4G63.(Dynojet)

Sounds about right. I know 4g63's can handle some power, is it an evo engine or older 4g. It would be nice if rotaries were as efficient at using there exhaust charge as a piston engine, nothing a bigger turbo can't fix tough

[RotorDad]

It's an older 6 bolt 4G63. He just ordered pistons & rods, to go with his new 67mm turbo. I have been trying to get him to do a RX7 when get the power he wants out of the Eclispe. What are your goals for the 240?

[FDwarrior]

^ Really I was only going for around 400-460 power wise. Im going to use the 240 for time attack stuff, and run grass roots racing with it. There are a couple of scca classes my car will fit in, and emra has enduro's. EMRA also has sprint races. I am going to come up with a water injection system using the electramotive to control it. The enduro's are only 3 hour and 4 hour races. Trying to do an endurance race with a turbo rotary is fighting an up hill battle. I think with a bullet proof water injection system it can be done. I would love to travel out west and try some tarmac hill climbs. I have to work on the driver modd more than anything. Im no where near a good enough driver to do any of the above. I will be attending driving classes and learning the next coming year. I really plan to just get seat time and exposing myself to competition.

[MaczPayne]

Impressive numbers! The 35R is what I'm strongly leaning towards for my power upgrades next year, looks like I'll be happy with that.

[FDwarrior]

I can say the car is to fast to have fun on the street. I look at opening the taps like playing russian roulette(Im not talking about blowing the engine either).
