How much does the hvh super sucker help ?

i just put one on but haven't had it to the track yet i just wanted to ask what your guys input is on these things ?

On my motor with a dominator it was 10 Horsepower with the 2 inch version. On my buddys moter with a 4150 carb the 1 inch was 7 HP and the 2 inch was a total of 15 hp vs a 1 inch open spacer on all comparisons (dyno tested).

I HAD THE HVH .....GO WITH THE JOMAR PIECE

Guy's correct me if I'm wrong,but don't you need to do some tuning after installation? (not just a instant HP gain)

I have a SS, just got the Jomar deal from Lem today..............Jomar deal is the cats ass....................

Super sucker is for sale............

What is the difference in the two?

it does say you have to rejet i just put it on i'm runin a little fat anyway so it might be good. It was only 50 bucks so what the heck i figured its worth a try.Now i wonder how it'll work on top of my zex perimeter plate

I have a hvh that I bought from Lem, are they already obsolete, can't keep up.

They both are better than an open or 4 hole spacer ...on the stuff we have tested . If i had a HVH unit that was doing a good job I'd keep using it . I.M.O. these are the reasons the Jomar units have the edge .
1] The material they are made of is much better .
2] A little more power in most applications .
3] Jomar guys are a sponsor of the "bash"
In that order .

Hey Jon how much? I don't have either.

Cut it out Melvin you dont need that i cant catch you as it is

Rejet is correct!! Lean is mean.....I "should" have been down to at least 88's or 87's squared in my 1050 in the heat.....

Another thing.........dyno's DONT go down the track......so its a trial/error thing. I have seen a "dynoed" motor run down the track, then swap the 2" spacer for a 1", and pick up 2.5 mph.........

Yes. I had to rejet down 2 in both ends of the dom. Its pulling a little more fuel thru with the up'ed velocity.

If you're already a little fat it's going to be pig fat.

Thanks for the info i was thinking the other way around.

I keep seeing this but the dyno will show you what your motor likes and doesnt if your chassis isnt set up for the power your making it can go slower and by changing spacers your dropping power to get the chassis working better, some adjustments to the chassis/suspension may have gained this guy more. and yes i understand that some small adjustments have to be made to correct for weather and such.
