Anyone test "Super Sucker"/ HVH tapered carb spacers?

On my W2 headed 416 with an Indy intake. I gained .3 and 3 mph with one. With a Victor W2 on the same motor couldn't tell a difference over a 4 hole spacer. The 4 hole spacer on the same combo was .15 and 1.5 mph better than a open spacer. Neither manifold had been touched it the top. I believe that was a problem with the Indy intake and why the spacer helped it so much. Jim

I've never had any trouble returning anything at Jegs. That's one of the main reason I spend so much $$$ there. Of course I'm close enough to go there in person and most of the employees are fellow racers.

Mine was on a Victor W2 also.

It made 12hp on the dyno for me.4150 style hvh super sucker.

A friend put one on his 416 indy headed duster. Didnt gain any et.
Guess he was the super sucker.

Well I picked one up today so I'll try it this weekend and post the results.

Every motor I have ever put one on, on dyno has picked up power/TQ..... usually 5-8 gain. Never seen a motor on dyno that did not pick up something W/ one.

I've been thinking about getting one of those too....

This is the one I want to try on my 400-3 indy intake with a 1 inch cloverleaf.

I plan on buying this one in the next couple weeks.

As with many other added/changed parts, don't forget that you may need to rejet the carb for optimun results.

You guys let me know what happens I'm looking for an extra .1 out of my car, and one of these on my 4500 flange converted indy intake just might do it...

I never had any luck racing them Dynos.

You show me something worth some ET and that what I'm buying.

I run a super sucker but it was worth nothing in ET.

buddy of mine got one
i think its a gimmick

dynos mean absolutly 0 to me
its what it runs at the track
all that matters

I run a Wilson 1" 4 hole taper spacer on my 408. For sure I gained 1" between the carb and manifold

I see a lot of folks running the 1" spacers...anyone using the 2" spacers? I have been considering a 2" to go on my Air-gap.

I didn't really get a good test this weekend. I'll try it again next weekend. I messed with the float level when I changed the spacer and the car bogged after launch really bad. So I returned everything back since 1st round was coming. Plus the wind was rediculous so I doubt 5-10 HP would have been noticeable with 50 MPH wind gusts.

69dart can you please exp. played with the flaots ...i did some work to my duster and it started with a bogg and would like to hear more on the flaot deal....also when you add a spacer how much jet would be needed i know most are diff. but what 1/2 sizes...sorry about asking ??? on your post but i want to go to a diff. spacer aswell got 1" open now and want to try 4 hole

I thought the floats were set too high on the front bowl so I lowered it down. But I was a dummy because the car wasn't on level ground and I messed it all up. After the bog run I parked on level ground and raised it back up (set to where fuel just trickles out of the sight plug).

The car ran 6.68 1st T/T - 6.89 bog - Went 6.71 on 6.69 for 1st Round - Then 6.73 on 6.71 for 2nd round. Wasn't real consistent but we had rediculous wind to contend with. It sprinkled just before 2nd round so she was moving around a bit. The weather was just terrible so I really wasn't too upset to pack up and head home.

had one on my hemi and it picked up over no spacer ,but then i took it off and installed a open 1" spacer and picked up my 60' 1.39 to a 1.37 i did this at the track back to back runs!! my car never 60' that good ever before so i know for a fact it was the spacer ,hey pro sport i'll lend ya my super sucker hvc ,if u want to try it !!! i think every ones car is different even if some one says" it" does'nt work i try it on mine cause it usually does !!
