there really isnt much tuneing, if any, for the TBI 3rd gens

man, id give you 300 bucks for them without the tires... is that WITH shipping?

 

i got an offer for 400 for the wheels. and its local. sorry

 

maybe try that vortec heads swap, they sure put a kick for cheap

 

Only 15 inch wheels? 350rs got 16inch on mine but now that i think about it? they did,nt come out til 91, and yours is a 89 correct? oh well anyway nevermind, and now back to the show.[sm=exactly.gif]

 

Just remember you can not make Horsepower by ADDITION. By that I mean you can not add up the possible gains from all your bolt ons and expect that number. Most parts work toghter and there final numbers will not be what you expect after a dyno run.

 

Exactly. HP doesn't add up like straightforward math. If you have three parts that are each dyno-proven good for 10 hp each individually. . . working together they may be worth 50hp total. Or they could be worth 20hp total. This is why benchracing never works. lol You have to look at how they affect each other.

For instance, somebody mentioned that helping the car breath will help. A lot of people will throw on an intake and a cat-back exhaust and expect huge improvements. You will see some improvement, but nowhere near as much as if you were to also use a low restriction cat, headers, new intake manifold, and new heads. Achain is only as strong as it's weakest link, and if you have restrictive heads (or whatever), that's your weak link. This is why you have to be careful of claims like "you'll see an increase of AS MUCH AS ___" ; they never tell you, "you'll see an increase of AS LITTLE AS ___" even though it's probably more realistic.

The latest issue of Camaro Perfomers magazine has an article all about a 305 buildup. It gains 105 horses from several boltons. I would advise you to think of any improvements as a total system, rather than just slap random parts on it and hope it works together.

 

Very good reply Turtle, exactly one or two might help, but the whole package is what there results are based on.

 

Thanks!

I forgot to mention . . .

Regarding the TB spacers; I'm not sure if there is info out there or not, but I figure somebody must have tested them on a small block Chevy by now. I know in the Jeep world, it's pretty much accepted as gospel that a throttlebody spacer will REALLY wake up a 4.0 straight six. It may not be a huge improvement, but I can't see it hurting. Unless it does, in which case, ignore me. lol
