Recently bought a 1981 Corvette, and would like to get rid of the air pump and other vaccuum "stuff". Seems like a lot of power is being wasted. Any ideas?
Air pump?

The air pump consumes less than 1 (one) HP, hardly worth removing it for 'performance' reasons. The rest of the vacuum stuff consumes zero HP.

Watch for emmissions
I wanted to get rid of mine as part of an entire engine overhall. One thing leads to another. But no question, although it may be a small amount, one less belt to turn & less wieght = increased power.
I went to oversized pullies on the other componants & headers and and and . But remember many states still have emmissions requirements for these cars, that they won't pass without the Air Pump.
In CT 25 years and over cars are exempt. So I had to pass emmisions two years ago (prior to engine work) then after that I could do what I wanted.
Also "Some" Ins Companies, won't payoff on a car that is found to have engine mods after the fact. So if you do Change or remove anything make sure you keep your Ins. Co. in the loop. A few extra bucks a year for coverage is better than a denied claim, when they find your stolen car but refuse to pay due to "Unauthorized Mods".
Good luck with this and future projects

Thanks for the info. I was just wondering how to get more than 190 hp out of the car without spending a lot of money. It was probably wishful thinking. Our state has no vehicle inspections or emmission checks! Would it hurt the value of the car if the motor has been modified? It is numbers matching with 36,000 original miles.
Thanks, David

In a one word answer?
Depends.
Would you get back the extra money you spent on modifying the car vs. leaving it alone? No.

...Depends.
I agree. The smog stuff could make a big difference at resale time if a potential buyer has to have it in order to title/register the car in his/her state.
Personally, if she's currently unmolested, I would leave her that way. 190hp will take you anywhere you want to go (except the track) on cheapo no-lead.

Original vs. Modified
My .02
I don't think 78-82's are going to appreciate significantly in my lifetime.
So, I modified my engine bay to suit my needs and taste. If you want HP increase, you need to do more than an Air Pump. There are lots of little things that can be done here and there that is the end will add up.
"All Original" cars are always going to have an appeal to certain people, NCRS is NCRS, but a well kept modified car will always find a home on the Show & Shine Curcit.
I'm not talking Radical stuff. Nitrous or Blowers, that really limits resale to people who want that.
I bought an all original one owner 82 CE (9k miles) back in 89 for $22,000.00. today 19 years later you can buy the same quality of car for the same price. You can also buy a dump for $10,000 or an ABOVE Average one for high teens. Basicly not much has changed in two decades.
But how many used cars can you say that abount?:L
What ever you do, enjoy the car nad don't second guess yourself. The universe has a plan for you & the Vette!
