Dave's 2002 Corvette

I am tempted to leave the Corvette exactly as it is.

While in Surrey at the weekend I took it for a bit of a drive down some "bendy" roads used by the local boy racers to kill themselves on a regular basis.

I really don't see the point of making it produce more power. I was unable to use all the power I had already.

Not helped by the auto box mind you. I found it best to keep the box in second and occasionally third. But I wish I had got the 6-speed version now despite my concerns over my knacky left knee.

I am tempted to fit some slightly stiffer anti-roll bars though. I have the Z51 type suspension already but a little bit extra help on very hard turns would work well I think.

I know what you mean by not needing more power, Dave I turned my Buick boost up to 20lbs and had nowhere to use it. Run out of road or license, one or the other becomes inevitable if not wary!
I fitted a Hellwig rear anti-roll bar, dont know if they do a Corvette version, but it has transformed the handling and was a lot cheaper than rival brands whilst still being a quality item.

Good price for Eibach. The difference with the hellwig bar is that it is located differently on my car. Ties the axle to the chassis via drop links rather than running from LCA to LCA. I guess by 2002 GM had that figured out

Aston Martin's £1.2M version of the Corvette.

Well you didn't want a long term relationship with me anyway did you Pete?

I am trying my BEST not to make any performance modifications to the Corvette but this one was going to cost NOTHING so.....

As on most cars there is a hot water supply to the throttle body to heat it so that in cold climates the engine gets warm air. A bit like the exhaust cross over though the manifold on our old Mopar engines.

However you get that hot water supply no matter what the weather. So there is a small performance advantage to cooling the throttle body to keep the intake air as dense as possible.

It is a bit tricky to remove the water hoses at the throttle body without actually removing the throttle body. I didn't want to do that as I don't have a spare gasket for it.

So I left the original hoses in place and just by-passed them from each end with a length of rubber fuel hose I had spare.

Now after warming the engine up the throttle body is still cold.

I was going to post photos but resizing is still giving me file sizes in the 450K range for some reason I am too tired to work out.

Maybe a stupid question but.........

Why would you want to increase the air temp around the throttle body and thus air going into the engine?

Back when i was into Jap cars the rule was the cooler the air the better. Throttle response, power etc etc. To be fair im talking about turbo cars, but can't for the life of me see why it would make any differece in an NA car.

...all about maintaining optimum running temperature in cold climates. In a normal / hot climate, you dont want it, hence Daves mod suggestion.

Clivey is correct. They have to cover themselves because some parts of the USA get down to -40 in the winter. Without heat you would have to run very rich indeed to keep the engine going.

The fact that cars are tuned to cover all conditions and still get good mileage is why a re-mapping of the engine is possible for more power.

Nice update on the ch*vy dave.

Working on something plastic meself at moment. Seems that anything that supports better emissions standards compliance is good, and that keeping things hotter helps - includes intake air, egr's etc. er..no.

Certainly c4's fan cut in is typically about 215 F with GM saying dont go over 250F...

Keeping the TB cool might be worth 10hp or so but how long would it keep cool with the hood down and the engines designed to run at such high temps I don't know....
