are carb spacers worth 200 bucks ?
 

I have heard up to 40 hp on the dyno as a result of swapping carb spacers.Is the wilson tappered 4 hole spacer really worth 200 bucks ?

Any recomendations for a 540 with a 1050 dominator ?

Re: are carb spacers worth 200 bucks ?
 

I installed a 1" taper spacer by Wilson and picked up some hidden rpm. I didn't pay 200 hundred bucks but the results I got were worth it. It did produce a leaner condition but I was running rich before the install. I hopethis helps.

HVH makes a super sucker for around $100.They work as good as any.40 HP is a pipe dream.10 to15 HP is more reallistic.

Re: are carb spacers worth 200 bucks ?
 

I agree with JC on this one. Petelle's 1" spacer is worth 10 to 18HP usually but a jet change is needed because it will lean the engine out.

I think 40 hp is a real pipe dream but if you want i have one i will sell you for 150!!!!
and i will install it for you.lol

40hp doubtfull, more like 10 at most. Its more like one of those every little bit helps mods.

Re: are carb spacers worth 200 bucks ?
 

Wilsons spacers are 180 bucks a pop !!!

I know HVH's works, NASCAR outlawed it 20+ years ago from Cup.

Why not just make one, they are easy!

Re: are carb spacers worth 200 bucks ?
 

What will the difference be between the one inch and the two inch power wise? Will it affect jetting alot?
I bought the two inch mad by HVH. I was trying to regain some of the low end that my combo is lacking. Have not tried it yet.

If I remember correctly I wanted to try some of these special 1" spacers like the Wilson and HVH Super Sucker about 2 years ago, but they didn't have any availabe in composite material (whatever it is) to keep the carb from getting heat soaked----they only had metal or hollowed out plastic. Instead I bought a couple of 1" 4-hole composite spacers and had JimV whittle a couple up for me to mock the high dollar ones a few years ago. JimV only charged me about $35 each.

so did it make any difference??????????????

I've got a pair of Wilson spacers, 1.75in. For the 4500's. New, $100 ea.

Spacers for the most part will help, but unless you have a dyno to actually see what the changes are you won't know. Most dyno guys will have spacers on the wall to try with an engine. "Point of purchase" if they make a good increase.

10 hp on the dyno is nothing on the speedo. I did it on my 454 Mag, only caused a too lean situation, especially on cold engine.....I would rather invest the money on the prop...and you have to adapt your fuel line as well...not worth it in aboat....just my 2cents.......

Re: are carb spacers worth 200 bucks ?
 

Spacers are a great tuning aid. They are used to make up for problems within the system. A 40 HP gain would generally only be seen when parts were mismatched, and the spacer was able to help overcome this.
As a rule of thumb a 4-hole, or tapered spacer will increase the air velocity going through the engine. This will make the engine think it has a slightly smaller carburetor, cam or intake. Generally it will richen up the carburetor, and improve the bottom end torque, and throttle response. It can also move the power band down lower in the RPM. While an open spacer will do just the opposite, increase the top end HP, and move the power band up higher in the RPM.
The thicker the spacer the more of an affect it will have on the combination. The only way to know specifically how it is going to work is to actually try it. With the amount of HP it takes to see a MPH difference in a marine application, you’re probably not going to see much, if anything. What a spacer can do on a marine application is help your jetting, and distribution in the engine, help with your acceleration, and possibly help try to match your WOT RPM with the prop you’re currently running.

I guess everyone has their own theory or motives, but I am a true believer in that while as long as it doesn't hurt it, every little bit helps. It can be a combination of a lot of little things I suppose.

I'm constantly amazed on the resources that this board can summon.

Thanks to all.

Re: are carb spacers worth 200 bucks ?
 

Were You Gonna Put Them????

Re: are carb spacers worth 200 bucks ?

Re: are carb spacers worth 200 bucks ?
 

DON'T..... DON'T...... Just don't... Now put the spacers down and walk away.
