H.V.H. SUPER SUCKER CARB SPACER

[lmchevy]

I was wondering if anyone has personally used any of these spacers and if they really work.The one i was looking at is the 1 inch phenolic for a dominator.

[jjam]

Just placed one on my car, I'll let you know. I was told between the 3 (open/4-hole/butterfly) the HVH butterfly will give you alittle more low end. But like I said just got it on my car. (dominator)

[slowman]

each spacer does a different thing,the super suckers work but only if you use the right spacer from the job.i'll give some cases, if the intake is to small in volume then you would use a open hole or if your not getting enough signal under the carb then you could go with a 4 hole. if the engine seam like it needs more intake volume and more signal you can use both . if you were to put a dominator on a mild big block and you can't get it to idle right and off idle through the first 2000 rmps are lazy and the timing and carb is close then you would put a 4 hole on it to increase the signal under the carb. but if you had that same big block that was built for all out drag and it seamed to run out of rpm early then make the intake volume lager with a open spacer.if you list all the stuff in the engine i could answer it better.

We've run for over 20 years now and the HVH is the best spacer we've used with ET and MPH results that back it up.
We ran alot of runs back to back over the years testing with open, four-hole, 1 inch, 2 inch, "plastic", wood, aluminum...cheap ones and the top of the line HVH versions.
Quick generalization:
The 4 hole helped the 60 foot
The Open designed picked up the top end mph
The HVH versions out performed on both ends of the track...the top-side being a four-hole that transfers into the open design was a stroke of genius on their part.
Go with the aluminum if you do alot of street driving or circle racing...go with the phenolic (plastic) if your drag racing.
We do have these is stock if your interested...
See Ya,

FLASHBACK351 : i was just wondering the diffence on aluminum on the street to phenolic drag racing im runing phenolic on the street just trying to learn you say you sell them do you have a web site thanks

[flashback351]

The phenolic ones tend to get "burned" after awhile...the process would occur faster if used for alot of street use. The heat from the engine cooks them so to speak.
The positives are: They are lighter and will keep the carb/fuel cooler.

Dave:

Try the HVH 1" spacer right side up - then upside down after you have a baseline on the first application, then try the second.

Yup! I have seen more power (5 hp & more torque) on some applications by just making this one change on an engine dyno. I know, it sounds strange and I can only speculate as to why it occurs. But, it happens on occasion, so give both a try.

The advice by the rest of the guys is very good. It all comes down to trial and error, but the 1" is a very good start and generally more effective than the 2". But guess what? The 2" may be better, you just have to give them a try, either right side up or upside down.

If none of them help you - try some shear plates. Comp Cams has some good cheap ones that may help you. Don't forget the fuel and timing changes when using all the combinations to make maximum power. Signal changes to the carburetor may require some more fuel and timing with every spacer or shear plate change.

Good Luck.

Now you've got me curious... :idea: ...I'm going to have to try that now!!
I've tried crazier stuff before!!

Maybe you could stack them and get multiple horse power gains,LOL did you ever think of that?

Them plates I feel are a waste of money for the HP increase you get from them.
What are they like 100 bucks,and maybe at best you "might" get 3 to 7 hp gains,and some are "0" gains.

Save your money,take your wife out to dinner.You'll get a better retirn for your money :P :P :P

[flashback351]

I repsectfully disagree, I've seen people spend alot more for 3-7 hp...our dyno runs showed more than that (and our ET slips before that) but we'll use your numbers, not a bad bang for the buck when your looking for any additional gains.

[slowman]

i have never seen any big power gain yet and tried them on aleast 40-50 engines. when i do get a power gain it's never more the 5-10hp so i have to agree with topsportsman save your money and spend it some were else.

[lmchevy]

Thanks guys on the info.I will save my money for something else.

[cepx111]

Granted these spacers may not be the best bang for your buck , but the fact remains they do work given that they are used on the proper application, it takes some experimenting to find just what works best for your combo, you just cant buy something and hope it works u have to research it and make a informed decision and go from there. I personally use a 2 inch open wood spacer that works great and I also use a KN stubstack to further inhance the air speed into the carb. Ive never had the luxury of a dyno to prove that they work I have to go by numbers at the track and without these 2 items on my current combo the car slows. Horsepower is expensive sometimes but thats what I love about racing and working on cars is the tuning and tweaking to get those few extra horses its very satisfying to me but then again some people would rather sit on the couch and say it cant get no better so I'm gonna leave it alone or its too expensive, yeah right like u didnt just spend an extra 200 or 300 bucks on that fancy carb or a 1000 on them bad azz heads...lol whatever.

I used to sell these HVH spacers and yes the plastic ones did burn up and the aluminum ones were better but I liked the fact that the plastic was used as an isolater but they didn't work for long... I had one customer return his plastic 4 hole that was so warped and disfigured I just was amazed at how it warped and melted... but I sold every one of them.. and the next orders came with DRAG RACE ONLY on the plastic spacers..

I let a Super Stocker buddy of mine try it ( HVH 4 hole aluminum x 1" spacer ) now his race car ran 9.72 with a open hole 1" spacer so he swapped it for the HVH and NO other changes to the car & it ran 9.60 .. believe it or not..that's a lot more than 15 + horse power gain on a 9 sec car..

I sold another one to a Super stocker buddy of mine and he gained 2 tenths on his 10 second camaro.. I currently have one of these on BBC 69 Camaro and believe me when I say these spacers are WELL worth the $100. to buy them.. my opinion only I don't sell them any longer but I do run a 2 hole spacer plate x 1 inch on my other car with a dual plane intake and it runs great, not a drag car..

[andybyrd]

well I'm no perfect engine tuner but I'm learning. I Have a 665 H/p 434 sbc in a 85 camaro that runs 6.20 @112mph in the 1/8 - I have a Dart intake with a 950 ultra hp Holley, I put a 1'' 4 hole wood spacer no change, I put a open 1'' wood spacer no change, I put a HVH 4 hole super sucker no change, it still runs the same no better no worse, is there anyone that could tell me how much larger jets should go with the spacers, my timing is @ 38 degrees and I've pretty much kept it there.
