C4 corvette guidance?

[46Tbird]

Or a 944 Turbo, Supra Turbo, Mustang SVO, LX 5.0 notch, ZR1 etc.....

How could you forget the two best cars of the '80s?

I like the later model C4s. I almost bought a 1992 ZR1 back in 04 but went with my 01 Cobra instead.

The very first time that I went to an auto auction, there was a 92 ZR1 with 31K miles on it running through. I nearly cried when they called sold at $7500. Someone got a helluva deal on that.

I'd hope you realize they each serve a completely different purpose.

They accomplish the same thing, but in different ways. Both have pluses and minuses, but both seems illogical to me. More electronics to deal with, and I bet tuning is a bitch with both.

Danny, don't you know better than to argue cars with crapstang? What were you thinking...

Really? So measuring manifold vacuum is the same thing as measuring the volume of air being ingested? No...

A system that only measures one of these parameters, infers the other. Measuring both is not a bad thing, or even unusual. Mitsu Evos do it, I'm sure there are others. What do you think all those tuners that add a 'three bar MAP sensor' to a MAF system are doing? They're just using actual manifold vacuum to determine load (and boost) so they can tune properly.

They're cheap! There was a high-mile one on Ebay a couple years ago that went for ~$9k!

I have a friend of mine that bought one a couple of years ago. Wonder if it might have been him? Anyway it's a nice looking car and he races every once in a while from what I understand.

Just get a C5 and enjoy being able to get in and out of the thing.

It's just a personal thing. I hate C4 corvettes for many reasons. Talk him out of it! They only have 205-230hp, look ugly, and they have a lot of little issues and low quality parts. Anyone I have known with one just wants to unload it after throwing endless amounts of money at it

The L98 cars were 250hp and the LT1s were 300. Get a 96 with a manual and it's 330hp. They really don't have any problems that any other GM product of the generation would have. Opti-sparks have some problems, especially if you don't know what you are doing and the intakes leak oil. Other than that they are pretty reliable. All Corvettes have their quirks though like rattles from the top and terrible ground clearance.

why have them both is the question!

i self-tune my evo x. it uses a maf + map hybrid system. tuning can be a bit more difficult because you have more variables to consider but overall it is better.

the ecu will extrapolate the load based from using data from both sensors but will bias towards a specific sensor for different RPMs. it results in smoother drivability and response and offers better control at peak loads.

pros:
maf provides true indication of airflow. it is also temperature and pressure adjusted.

map is absolute manifold pressure, perfect for controlling a boosted application

cons:
maf is vulnerable when air entering experiences turbulence before the sensor as well as the obvious: it can be impeding of entering air flow.

map sensors can only calculate theoretical airflow and are more susceptible to environmental changes as well as lack of fine control under vacuum to boost transition.

The late model C4s are one of the sexiest looking vehicles ever made, imo. My cousin had a brand new Admiral Blue '96 back in the day, and it was Tits McTitterson from Tittleyville.

The C5 styling is just "meh" to me, although I do like the C6.

Again, that's just based on looks. Compared to today's cars, they were all slow turds back then, right?

Do they not serve the same purpose?
I said never said they functioned the same. I'm all for learning something new, so why have both?

Was it a Grand Sport? The only Admiral blue '96 Vettes were the 1000 Grand Sports w/white stripe + red hash marks on the left front fender.

No, it was solid-colored. He worked as a mechanic for GM and won some kind of contest where he got his choice of car for a year for free, and that's what he chose. I'm 99.99% sure it was a '96, but now you have me wondering. Maybe I have the color wrong. It was a dark blue, almost looked purple from some angles.

EDIT: I just looked up the color, and it was definitely Admiral Blue. Perhaps it was a '95.

Damn, looking up pics of those online has me drooling. I don't understand why people say the C4s are ugly. So sleek and smooth...

[Cobraman]

I loved the look of mine.

Must have been a 95. Great color for those cars. I had #171 and wish I had kept it. The lt4 6 speed cars are a blast. Was very reliable and solid too.
