Got me a new car!

I should buy a cool car too. But I'm not a car person. I don't know shit about cars so just screw it
 
hehe, i just bought a 2004 rx8, wanna race?

Rofl, sure. Wanna lose? Well, if it's stock it will get hammered. They may put out, what, 235 hp? But that's nice since it's hauling an extra 500-1000 lbs :p
 
Someone bought the bike I wanted. ):

Oh and damn, Pitz your car is in really good condition. Maybe better than my 92.

Damn, if you don't need your taillights, I need a good pair of S5s!
 
3" exhaust? Say bye to any torque had to begin with.

except it's got more than plenty.....

You're the ONLY one I've heard say that I'm going to have no torque with my 13-B TII rotary.....

Well...I know dramatic things happen when you run something like NO exhaust, like open headers or even open head. But I have never seen an aftermarket exhaust from a reputable company that removes power...
 
The car is turbocharged.

So what's his face said that the 3" exhaust took away torque...which means if the turbocharged car makes XXXft/lbs of torque, then you put on this exhaust (let's say it does remove torque for fun) then your car makes (XXX-y)ft/lbs of torque.

It's not like, because his car is turbocharged you can install any power-robbing parts and not get robbed from power.

it's car+turbocharger+power robbing part = final torque
not car+power robbing part = final torque + turbocharger


unless of course I just misunderstood what you were saying, then just ignore me.
 
I don't even understand where you're getting at the "losing torque" part. The turbo is pushing shit tons more air into the engine. The more air in to out the better. Having a 3", it's big, but nowhere too big.
 
Naturally aspirated cars will gain top end power at the expense of low end torque if you open up the exhaust too much. Same theory applies to camming and adjusting your lifters for extra duration.

Turboed cars are less susceptible to this as they have generally positive manifold pressures. Turboed cars have more dense and therefore hotter exhaust gases, and as we know hotter gases expand more quickly thus need more space. Scavenging is not considered in turbo cars. Increasing exhaust diameter alone won't do much for the car however, as the fuel map and maf will be feeding an unchanged compression of fuel and air. Unless the exhaust was initially restrictive or boost is increased there is no reason to change it. even if it is restricitve, the muffler or cats may be the only restrictive components.

This is what I meant by it, Pitz. 3" is big for a street car, and having too big of an exhaust can kill torque. Backpressure = torque. Forgive me, though, I forgot your car was turbo'd.
 
Stock piping on my car (6 cyl boxer ~230bhp) is 2.25in from the headers, 2.25in single into the muffler out again at 2.25in. I'm running 2.5in muffler deletes and the cats (all 3 of them) are stock and highly restrictive but I tihnk it netted me some top end without sacrificing low.

The guys supercharging for something around ~420bhp are using 3in duals into ones into duals or true duals. The power bands just go straight up as boost builds. I think unless you are cranking around 200hp+ through a single pipe 3in should be ok.
If you aren't making enough power your gases won't be able to reach the tailpipe before they cool enough to cause backpressure. Just look to see if you are spitting water out of your pipe. That happens when exhaust gas condenses due to being cool, relatively ofcourse. Cool might be like 130 degrees.

....stop....saying....back pressure.....

Since when was an engine EVER about restriction?! It drives me wild that people suggest that having forces working AGAINST the motor is a good thing...and don't even try to say something like 'the compression stroke.'

Scavenging is not considered in turbo cars
I absolutely promise you, any professional racing team running turbo cars (think old F1, new prototype cars, etc) has considered it. They don't just go, "oh it's a turbo car throw some pipe on there and make it exit here." Stock turbo cars aren't able to consider it as much because things that are 'more important' take precedence...like volume.

What are you going on about?
I don't think you understand the context of what I am saying.

I should have elaborated. Street tuners.

The vast majority of street tuners NEVER consider it.
Ask any random person. They will wonder what the hell you are talking about. I left the front half of my exhaust stock (NA) because I know on my motor the scavenge creates a lot of torque, but it took a Subaru master tech to teach me this and still not everyone in our circle is convinced even though we are proving the results to them.
My friend with his WRX just put the largest downpipe he could find and got an ecu tune. He probably has never heard the word scavenge used in automotive terms in his life. Same for almost everyone I know.
 
Screw the exhaust. I'm only putting a different muffler on mine to cover up the whirring noise from the power-steering pump.

On my old 7, I was going to put silencers on the damned thing for shits and giggles...make it quite as hell.

Then I thought for the next second, slapped myself, and said, "I have the stock exhaust! WTF!?"

But yeah, I'm liking the exhaust, except it's leaking up where it bolts to the engine. I've tightened the screws as best I can, but it's still pushing out some air. So I'm going to have to put it up and see what I can do with it....
 
Reminds me when my friend's exhaust completely fell off his '93 Geo. fixed it with duct tape until we could get a welder. Same guy also blew up the muffler in his '87 Jeep Grand Wagoneer.

Pitz maybe you could take it off and put a silicone caulk bead around where it leaks, that might seal it up, if it doesn't melt. But hey its the $5 fix, if you want a professional job it is your choice.

*HOLY RESURRECT!*

I've got that part, and I've taken it apart and put the seals all back together. Now I've just got to get it onto my car...and see if what I did works. ;( If it doesn't, I'm going fkn premix.
 
I've got myself a car too :O :D :D :D

Peugeot 106 :D

?900 insurance :D

Though weird driving without powersteering :O

You should try driving when the powersteering cuts out on a volvo 940 estate whilst you're pulling out of a garage.
 
ive got all the power steering i need..

/flex
MOAR horsepowah plz

I'd hate to drive a car where the PS kept cutting out...whew.

Who wants to help me change my OMP out this weekend?
 
I didn't see this thread, I'll just respond to the original post.

When I was young I used to have an '87 RX-7 and here is my story.

I had EAGLE alloys model 077 chrome and a body kit, lowered, competition stereo, new seats, dual thrustmasters. I had it painted jet black. It looked like a new car.

I tried to get it converted to a turbo engine, but the guy backed out after he sold me the turbo hood.

I met this girl who had a baby blue turbo II and she was going to trade me, (since she didn't care about it being faster, and mine looked way better) but I was drunk, got in a domestic despute, took off and wrecked it, got it fixed, then the transmission broke shortly after.




I don't know if the Turbo II has the same problem as the NT, but with that car, there is a defect, if you start the engine, and turn it off without at least letting it idle for a little while, it will flood, and the next time you try to start it, it won't start, and you will have to wait days to start it again, or else you can take the plugs out and dry them off yourself. This happened to me three times. In case it never happened to you, you might want to look this up so you know what to expect.


Here I have some things that if you don't know already, I see you have 2 of them but I want to make sure you know.



Anyway, those cars are pretty sweet, but that car is old, so take it easy on it. And be careful, while the handling is ****ing incredible, you are made of like 90% water. You know what a water balloon looks like on impact?

I think the statistics go like this:
For every 10 miles per hour over 65, your chances of dying in a crash double.


OK, and finally, parts for that car are really expensive when new, and getting harder to find when used. (at least in the US) But it looks like you have a parts car there in the driveway.

BTW rotary engines seem to last forever (literally) from what I know. It's the transmission you have to worry about, so don't drop the clutch.
 
Nice to see it's manual transmission. It's 1000 times better than automatic.
 
Just added a 1972 Chevrolet Suburban to my list. Still have my 2000 Toyota MR2 Spyder. :)

They are old, and if they were taken care of, they can do shit most cars 10 years newer can't pull off as well. Once you get used to doing drifts/taking corners fast/etc, you'll learn to deal with the 50/50 weight distribution. Since most cars don't have that, most people aren't used to that.

Haha, yeah, a crappy parts car. Doesn't have what I ever need. and yeah, I know parts are expensive. A freaking Metering Oil Pump is over 200 bucks brand new...when I can just order $2.50 worth of seals to fix it myself. Imports, what are you going to do, right? hahaha.

Yeah, they do alot better than regular piston motors, for the soul fact that they have less moving parts. With just the 2 rotors spinning in place, which keeps up in performance as a 6 cylinder, that's 6 giant pistons slamming into the block *not technically, but just giving an idea* I've seen 7's, with a blown rotor none the less so it's a shitty car* last at 9k RPMs for 10 minutes. How many piston motors can do that? ;) They are definitely a stout car, and they do well. they just require more maintenance then other cars. But that's OK, it's nothing serious.

This cars compression is running into the REQUIRING a rebuild stages, and the fact it is still pulling ~200 horsepower, and not giving me any problems that can't be fixed by hooking up my BAC....Just goes to show. This is my new baby, and I <3 it. :D

Good to see another 7 owner. What model was your 87? GXL is my guess?

Yeah, I could do some rediculous shit in that car. I would drive it sideways sometimes. It was so low to the ground and the rear wheel drive and low torgue meant you could floor the gas through any degree of turn and stay gripped. I would have to intentionally lose the rear. Rear wheel drive is great and I miss it.

It's quite a contrast to my current car, a ~270 HP eclipse GS-T (front wheel drive) I can't give it hardly any gas at all until I'm going straight, and the torgue pulls my steering wheel everywhere ('torgue steer' - can be fixed by installing a limited slip differential), so It can be a wild one trying to keep it on the road under full throttle in low gears. The power goes to the wheel that is easisest to turn, so thats what makes it pull my steering to one way or the other. Wait until I get a bigger turbo, intercooler, and an Air/fuel computer, I'll probably wreck it. :(

Hmm, I don't know, I bought it from a friend for 2,000. It had what were probably the most expensive wheels they offered. not the turbo wheels, but really thick polished alloy sport wheels, if that helps you determine.

It didn't have any badging, It had a really sweet looking rear skirt and a unique spoiler. One of the side skirts was cracked in half so there was no side skirts, i got them seperately, fixed it with fiberglass repair, and had them painted with the car.

the front skirt was stock though.

The car was very low, and so it looked tight.


Again, there was no badging, but it was a 5 speed, but it was slow as hell without the turbo. it's a fairly heavy car compared to the other gen RX7's so that didn't help. Then, the entire trunk was a speaker box made of particle board with carpet making it a lead-sled.

You could clearly hear what song I was listening to in this car from further than you could see it though. I added a ton of speakers and amps, because that shit was pimp, and I always dreamed of doing that. It was my 3rd car. I lost a significant amount of my hearing ability though. DOH. I was a stupid show-off. I should have definately had hearing protection, but I never did. I would be in pain sometimes, and my ears were always ringing.

In my eclipse now, I sold it all, and don't have any of that. It makes a HUGE difference. It's light as I can make the car. I even got a racing carbon fiber hood. A few gallons of gas in my tank and I can feel a big difference even. I guess thats the bad thing about 4 cylinders. They are great at whipping around light cars, but the eclipse is pretty heavy stock. This car is really fast though, I took EVERYTHING OUT and re-did it with lighter weight stuff. It's all hidden behind light wieght panels, and underneath its just a gutted car (bare metal)

I just need to sell these chrome wheels. They are really holding me back. I put them on a scale and they are 46-50 lbs. (can't remember now) each with tires.

I'm too lazy and busy with my computer lately though. :dork:

These are the same wheels that I paid $1450 (w/tires) for my RX7. I did some research before I bought them to find that my RX7 had the same wheel type as an eclipse. So I thought hmmmm... I could deal with a turbo eclipse. So I had already decided to get an Eclipse well before I decided to sell my 7. About a year later, I sold the RX7 when the transmission went, and took the wheels and put them on my eclipse.



They have racing wheels for about the same price these cost that weigh like 12 lbs without tires. With tires, some racing wheels would probably weigh like 32-37 lbs each. (I need the tires really wide ((heavier)), especially in the front with ~275lbs torgue/HP FWD) So I guess I can shave off 50 lbs or more. That would be a very significant improvement. I can't wait.

I feel like I need it. The acceleration is a drug, it's addictive. I need more and more to get the same high. I mean, you know, you have ~200 HP, and it's fast isnt it? My car feels like a rocket taking off sometimes. Its exhilarating. On the highway, on a cool night, it's a scary ****ing car. It accelerates very hard in any gear instantly, and the faster you accelerate, the less time you have to calculate other vehicle movements. wEEEEEEEEEEEEEEEEEEEEEE :D

Danger is fun.
 
I think that my car has more torque than horsepower...
 
this is what I got:

YAY FELLOW MINI OWNER!

'Cept I don't have the S... but it still kicks ass. Mine looks just about the same, except its the 2007 version of that color (mine's a little darker I think), with the white stripes and roof.
