Re: A4 Shift Points (GrayGlenn)

Why is it you do that? Is you engine heavily modified?

As far as part throttle shifts go, you can control them with your right foot. You can control downshifts fairly well also. My '97 will stay...

Re: 90mm TPIS Throttle Body Users.................... (J-Rod)

Yep. This may also be related to the limp-home or fail safe modes in the PCM. If the engine lost electrical signal to the TB, if it closed completely the engine would most likely stall if the...

Re: Twitchy handling (Charley Hoyt)

Front toe OUT, even a little could cause this.

You might have another alignment done by a different shop. If they have trouble getting the alilgnment there might be deeper damage.

Re: HOT throttle body vs cool one (YO-EL)

Same % of O2, about 20%, but less dense air of course means less O2 per cubic foot. So I guess "yes" would be the answer.....or maybe "no". :)

Re: May be a stupid brake question... (Evil-Twin)

I agree with your assessment of some posters. There is a lot of mis-information thrown out as gospel. Some forums are worse than others in this respect. Unfortunately we all don't have out CV in our...

Re: Throttle body spacer and other questions (jl240z)

Did you hear that GM had them on the prototype C5s but left them off to save weight, and at the request of the big oil companies? Goodyear wanted them to use it because they wanted to sell more...

Re: Are Torque Converters really hard on your transmission? (JAvery20)

200 would get my attention. If it's warmer than the coolant the stock cooler in the rad isn't hacking it. When it got warmer than the engine oil I'd probably get concerned.

Re: Thoughts on c5 aerodynamics (Kenny94945)

Probably not at all. The air leaving the rear edge of the car doesn't try to flow tightly in behind the car. In fact there is a fairly low pressure area there. Watch the water mist behind a C5 in...

Re: (TTPMatt)

Yeah, you are right, Matt. I didn't get any responses anyhow. I doubt that I will since I'm not a sponsor.

Good luck.

Fully agree on internet pricing on lots of things.

Re: Why does C5 like gas on exit? (BlackZ06)

Jon,

In reference to ...

I agree to a point. You are changing the front tire loading dramatically, which changes the lateral force, BUT other things are going on: under hard acceleration, the...

Re: How can I make my car handle more neutral? (Cobra4B)

The problem when you are trying to generate nearly a g of lateral acceleration in a 3500 lb car at 30 mph is that the front tire is trying to roll under the wheel and it's probably decreasing the...

Re: WILL AN A4 TRANNY SHIFT INTO OVERDRIVE AT W.O.T.? (ELIJAHCOLEMAN)

With a 2.73, 5600 rpm shift (no converter slip) from 3rd to 4th is at about 163 mph. Figure 157-160 or so. My 3.15 with a 6000 rpm shift get 4th about 145 or so.

Yes, it will shift into 4th @ WOT...

Re: How can I make my car handle more neutral? (Cobra4B)

Sorry I didn't read your siggy.

34/32? For max low speed cornering (auto-X) those front pressures sound kinda low. I'd expect a lot of shoulder or even scrub onto the sidewall at least on the...

Re: How can I make my car handle more neutral? (Cobra4B)

Thoughts:

Adjust front tire pressures, and maybe rears. More front might help.

Are you trail braking? The rate at which you let off the brakes changes how th car turns in. If this doesn't...

Re: Why does C5 like gas on exit? (BlackZ06)

No offense intended, Steve. We just look at things a little differently... or maybe we just explain them differently.

Re: Why doesn't the C5 use an EGR system? (rhneff)

EGR and other emission systems are "excess" weight, and weight saving was nearly Job One in the C5 design. By keeping the car lighter, the engine works less (during an emissons test and on the road),...

Re: Why does C5 like gas on exit? (BlackZ06)

You don't really change the front/rear weight distribution very much with mild acceleration, but you do ask the rear tires to provide froward thrust when you accelerate even a little, so according to...

Re: Tire Flat Spots From Storage? (torch red ryder)

I drive mine most of the winter. Snow over a couple of inches about stops it on summer tires. In a pinch you can do the "tractor pull" thing and spin the wheels about 40-50 mph (traction off, of...

Re: if i do not use run flat tires what will happen?? (fxrhm)

When I start a drive (w/o runflats) I check all the tire pressures before I get too far from home, or work or wherever. If one goes flat from a roadhazard, it's roadservice time and the rollback. No...

Re: C5 and unsprung weight (eRiCdWoNg)

You are right! As for rotating inertia (flywheel), remember that the engine is spinning about 10 times as fast as the wheels in first gear, and you don't do much fast acceleraton in 5th or 6th (or...

Re: Not safe to drive the vette when it is cold and damp. (cscollis)

Summer tires don't like cold weather. They get greasy about 35F or so. It's not just tread pattern that makes tires all season or winter. I drive mine year round. Coldest this year was -15F. You...
