Well I finally decided to move on to the 3L Intake conversion. I have a few reasons why. For one, I wanted a little more low-mid range torque to it. Then, I also wanted to have a Cold Air intake installed because the heat soak from the HAI was getting on my nerves. I didn't want to go through another summer with heat soaking issues. This will allow me to use a CAI from a 3L (Mazda 6). Along with the install, Dom is going to install the rear sway bar, and have some extra things to improve the driving experience of the car. I'm looking forward to it.
Well I've been back and forth with Dom concerning the installation of a '96-'99 3L Intake system on the hybrid. We've discussed potential gains and losses. So far I should be able to expect a gain in torque throughout the entire rpm range, which would be a nice welcome. The potential downside is a loss in peak HP. We've also discussed honing the UIM for even further gains. With this he said that there might not be losses in horsepower.
Sor far that seems like a win/win situation. The downside is upgrading to that. It certainly won't be cheap to convert over to the 3L intake as I would like to install a CAI and I would also have to get a battery relocate kit because of the relocate. Let's not also forget about the retune cost.
I can recoupe my costs with the 2.5L SVT/ST200 parts I do have. Max Extrune honed ST200/SVT UIM (Got it from BAT a long time ago and had it Max honed), SVT LIM and Optimized SVT TB. If anyone is interested at some point in the spring let me know via PM.
As I'm approaching winter time, it's getting time to put it away for the winter. So far the only issue I'm having is a dying Optima battery. I think there's a dead cell and I can't get a good charge from it. Next time I'll get an Optima Red top for better Cold Cranking amps. I don't really need a deep cycle battery anymore.
Other than that it runs great. The COP system starts up every time. Now that I put a couple thousand miles on it, I'm liking it. I seem to have more of a gurgley sound when I get off the throttle, probably from the COP and the retune. Overall everything is as smooth as silk.
I miss the 3L LIM though. I did like the improvement on the low end torque. However, I had to go back to the SVT LIM because the ported SVT heads were creating a vacuum leak. That totally sucks. I still made great numbers and still an improvement over my original tune. I'm 225whp/ 201tq. There's not much else to do to this thing besides a CAI or perhaps long tubes (if that ever happens), now I'm moving on to other plans...
I've been able to put some miles on the COP Hybrid now. I've done some rigorous testing (save for drag racing) on the COP system and it's work phenomenal. With the retune the car is actually a bit quieter and sounds great. Throttle response and torque feel great! It's nice and smooth throughout the entire powerband.
Right now I'm testing the "Sweeping turns and oil press loss" myth. Call me the myth buster lol. So far I've taken on and off ramps from anywhere from 40-60 mps in 3rd gear (can't really do it 2nd mph limited to 55) and oil pressure stays the same. I even punch it coming out of the turn. I still have the 2.5L heads and SVT oil pan. Yep no "oil pan upgrade" here. As I do have the oil press sensor installed off the main gallery, I can read oil press. accurately. I guess what people don't understand is that :
1: Not much oil goes up to the heads. Only a certain amount of oil is needed for the cams and valvetrain. After all you can take the oil fill cap off while its running and not get a face full of oil right?
2: As Terry Haines has mentioned In His Con rod/bearing thread it has more to do with the rods than anything else.
See I had a rod bearing on its way out. I had the symptoms, flashing oil press light at idle, weak idle, etc. Last year I DROVE it all the way to Ohio to get it repaired and guess what, it still runs as strong as ever.
I guess what most people fail to see is that there is a Huge Oil drain passage at the timing chains that prevents oil from staying in the heads even if there was to be some clogged condition on the oil drains.
Well I'll keep everyone posted on it. I'll be enjoying it!
Last weekend I drove up to Ohio to drop the Cougar off for some transaxle work. I had a great time hanging out with Brian (Racerx), Dom and Billy while I was up there. Dom is sending the tranny to Terry Haines to look at the 3rd gear issue and do some upgrades to it as well. While it's at the shop, Dom is going to look at the small oil leak. The cause is more than likely the crank seal, probably due to a possible scored DMD from being removed and installed quite a bit. I also asked him to look at doing some rewiring of the battery cables (fix my screwup lol).
I decided it's best to leave the wiring and electrical work to the hands of a professional rather than do it myself. I think I'll stick to radio installs and minor vehicle maintenance. I've been impressed with the quality of work Dom puts into my car.
There's some other things on the list and I'm glad that while it's there it'll be looked into. I may put on a fresh new set of tires on it as the current tires (Yokohama Parada Spec 2) are showing wear signs as well as get on my nerves with the road noise. The exhaust is loud enough and adding the tire noise doesn't help. I looked at the Yokohama S.drive tires as a suitable summer tire replacement.
Dom also pointed out that there is some small bubbling on the roof of my car by the washer nozzle. Yay. I was thrilled to discover that. So I guess I'll have to have that looked at some point in time.
Overall I'm fairly excited and I can't wait to get the car back.
