Here is a 2 minute ish video from cars and coffee.

 

Damn, that sounds sweet!

 

Congrats you guys!!!
That’s one sweet ride… bro thats was only 4k rpm’s and it sounds awesome.
Can’t wait to hear it at 8k rpm’s

Steve

 

Yeah. It's crazy how low rpm sounds. Does not sound like low rpm haha.

 

Week of 5/27 - Addressed small oil leak issue with the oil pan along and fixed small coolant leak

Week of 6/10

o Engine being broke in this week. We have put over 100 miles on the car.

o Rev limiter raised from 4k to 5k rpms

o Ambient temp is around mid-80s, coolant system is working well and will not overheat after idling for 30 minutes

o Oil pressure remains to climb as it engine reaches 5k rpms

o Power steering connected but needs a belt

o Pedal is still heavy and hard to tip in but drive able

o Next up – alignment

Will post a 1-2 minute video of my buddy driving it in the next day or two in the meantime, here’s a pic of what the slide throttle looks like apart.

 

Almost 500 miles on the engine. Will turn up rev limiter to 6k for the next video.

 

I approve of the new exhaust configuration
Sounds so good

 

Sounds good, what changes were made? It can be really hard to contain N/A rotary noises to keep your ears from bleeding.

 

^ Removed muffler closest to the bumper with a strait pipe. There is still a muffler/resonator mid way in the exhaust.

My buddy talks about it and shows it in his video.

 

It sounds cool in the video but also sounds louder than I'd want for a street car.

 

The car's weight with a half of tank of gas and small tool bag. I also thought the weight distribution was interesting.

94 PEP

 

Attended Import Alliance on 7/19 and 7/20.

Drove the car to the meet on 7/19 (34 miles round trip) with no issues and didn’t have any issues getting to the event on 7/20 until I was 200 yards or so from the parking spot.

Noticed some smoke coming into the cabin and it smelt like burnt plastic so I shut the car off. Tried to restart and didn’t have any luck. Starter wouldn’t turn over. I had power to the ECU and cluster but couldn’t roll up my windows or close the sunroof.

After some troubleshooting, my buddy noticed a burnt turbo timer that I forgot I had.

Towed the car home, did some additional troubleshooting and noticed some burnt wires to the Flasher / CPU. Reached out to Tomsn16, got an OEM connector from the body harness, replaced some wires and removed some aftermarket wires and it appears the issue is resolved.

Will be doing some test drives this wknd.

With ambient temps around 85 degrees. Coolant temp has been around 185-190 cruising around. Oil pressure will get up to 110 or so as RPM increases.

Engine probably has around 650 miles, rev limit is still at 5k as I need to refine the tune to before I increase the redline.

 

And here is a video of my buddies sister driving the car and her thoughts on the car.

 

I found this thread by perusing the gallery and the incinerated turbo timer caught my eye. Started reading and thought to myself, Hey I know that car from somewhere...Low and behold you're the owner! Id only seen the videos posted on RAD-x7's channel, so its interesting to see the behind the scenes. Very cool!

 

I'm sure the neighbors love hearing this car.


No major updates, just enjoy looking at it and hear it idle.

Would like to remove the OEM relay and fuses to clean up the engine bay.

 

Amazing dream build right there! Looks and sounds amazing, would be amazing to drive

 

I didnt know it was being tuned by Defined Autoworks.
Amazing choice for an amazing car!

 

The car has been down the past couple of weeks to address a few issues

Issue #1:

I’ve never really liked the pedal feel as it took a lot of effort to open the slides and it was tough to barely open the slides as I had a really heavy return spring. I had to have a really heavy return spring to close the slides. After hours of troubleshooting, I decided to machine the intake to ensure I had a flat surface to bolt the slides to. Well the machine work fixed that issue as of now. Will be interesting to see if anything changes as it goes through various heat cycles.



Issue #2

The slides didn’t open up fully due to mechanical and TPS limitation. This was addressed by trimming some plastic off the pedal so that it travels further. The TPS limitation was address by a custom bracket that allowed for more travel.






Issue #3

Had a PS leak at the rack. I think the root cause to this issue was a bad bajo bolt as the threads on the one I had was a little missed up. I replaced the bolt and washer and it seems as my leaks is addressed.



Issue #4

The alternator belt was a one rib to narrow and was slight off center. I noticed that my belt was getting missed some and checking the alignment with a laser. My buddy noticed it was slightly misaligned. A spacer fixed this issue. And lastly. After some additional research, my buddy was able to find a 5 rib belt that the correct length.

I’ve put 24 miles on the car since the changes and plan on putting another 100 miles on it this weekend.

Currently thinking I will dyno the car in Dec or Jan.

 

Weather here was perfect and the wife got to drive the car around some.

 

I love the way the slide throttle looks.

 

11/4

· car got tuned by LMS-EFI

· Made 350whp and 275tq at 7k RPM

· Fuel pressure was dropping around 7500 RPM so we didn’t take it up anymore

· Using stock oil pump and pressure was around 110 psi at 7500.


11/9

· My buddy Erich from RADPotential took the car Seven Stock and was able to do a lap or two at a private track day. Can’t wait to see what the video on this day.
- Nice to see other people appreciating the car.







Engine currently has a little over 1000 miles.

I’m looking forward to driving it to the next local cars and coffee.

 

Looking good.

Curious, where are you taking the oil pressure reading from? The rear iron or front? If at the rear, you might want to consider moving to the front to see if there is any drop off.

I ask because I was under the impression the stock pump wasn't able to handle duty at high rpm on a 4 rotor. But also just saw on Adam LZs new billet 4 rotor he changed to wet sump with stock oil pump and drifting the car at high rpm. I didn't expect that to be sustainable.

 

^ oil pressure is on the front iron.

Yea, I was thinking my oil pressure would start dropping above 7k RPM.

And I also noticed Adam went with a wet sump and driving it pretty hard. How do you think his car sounds to mine?

 

It's really hard to tell in videos, but yours sounds better to me. You've got Logan's headers which are great and a nice exhaust. Adam also has nice headers, his fab guy Rohan is really good, but I think it has a titanium exhaust and I don't think that does much for the tone.

What I was surprised about is the place that built Adam's engine (I think whoever made the billet plates, not billet pro or billet boss, a different one haha) told him it's good to rev to 10k with the wet sump. I just don't see how that can be. Maybe it's because there is less force on the eshaft when only pushing 350-400whp. But in higher horsepower applications maybe that's where it becomes a problem.

Whatever oil pan he is using must be awesome in terms of baffling though. Drifting is not easy on oil slosh.

 

Honestly, it's no comparison. There is something wrong with LZs car. IMO it doesn't sound like a 4 rotor. To me, the sound has more in common with a 3 rotor than a 4. I don't really know how to describe it, but I've actually contemplated if they chose a different firing order or chose to go with different phasing of the rotors for his build. I ultimately don't think that is the case, but I really believe the issue is way deeper than their manifold design or the titanium exhaust.

If you think about all the other 4 rotors out there, most have different porting (side port/PP), manifold designs (4-2-1/4-1/etc), and NA vs Turbos...so they all sound a bit different, but they all inherently sound like 4 rotors. His just doesn't. I've been told by 2 different people that it sounds different in person...but I have experience with George's (David's) car in person, so I know the subtle differences in the sounds in person vs on video. It's too far off IMO, and I can hear that chainsaw-like undertones of a 3 rotor too predominantly. I hate sounding like I'm bashing the kid, cause I really think he's doing all this stuff for the right reasons, and he enjoys it. I don't think he's just chasing the algorithm. I really wish him the best.....but he needs to surround himself with better people, at least in the rotary space.

Sorry for the sidebar, but to your car.....I feel like your car sounds like the love-baby of Dahm's turbo sideport and Logan's NA 4-2-1 car. It sounds awesome. I personally like the sound of a 4-1 header 4 rotor a bit better.....but that sound difference is SOOOOOO minimal. Your car sounds fantastic.
