I had full intentions of using a Vic jr on my build, however after a conversation with one of the guys at Btr, the Super Vic was highly recommend over the Vic jr, even on my mild combo.

Build is as follows: stock long block Lq9 (may have 799 heads to bump compression soon) with 232/244 111+4 cam. Converter flashes 4,700, 4.56 gear and 3,050 lb car.

Granted this will mostly see time at the strip but I wanted some thoughts and experiences from you guys before I throw a Super vic on this mild build with a 6,800 max rpm.

6800 rpm naturally aspirated engine I would stay with the victor jr.

I have seen several people with builds ranging from similar to yours to 400", 7000 RPM strokers who had a Vic Jr and then tried the Super Vic. They either went slower with the super vic or did not go any faster over the Victor Jr..

Everybody thought they were going to pick up, but no dice.

I appreciate the response. If anyone is having success with the Super Vic on a similar build, let me hear it. Right now its looking like I get to save some money and go with the Jr.

I have a vic jr on my stock bottom end LQ4 with L92 heads, and a smaller cam than you have, 9.4:1 or what ever the comp. works out to, glide 1.80 first, 4.10s, and 3405lbs with driver.
I went 11.31@121mph
and 9.42 @ 143mph on a .028 jet in the fogger.
Shifted 7400rpm N/A and 7000rpm on the spray.

From what I've seen and read, anyone that tried the super vic didn't see a huge improvement.

Here are some links to comparison threads

There is a thread on here or yellow bullet with back to back track testing of a LS3/L92 vic jr. vs super vic. I can't seem to find it at the moment.

If I were you just go with the Vic Jr, and take out the injector bungs.

Thanks for the links Petty Pop. It looks as if the gains from the Super are minimal on those combinations even though they're a little more radical than mine.

Is there any general consensus that these LS/ Vic Jr combos like a spacer for more plenum volume or is it as usual, a case by case basis?

I think it would work on the carthedral heads but the ls3 heads is so much bigger, I didn't think it would work,,, that's benji's mustang that he did the swap at the track,, when I get mine back going im going to do the swap at the track,, and see what diff it would make.

Also I tried diff spacers at the track and no diff in ets with my car,, but I think I was out of carb <not big enough

Nickelndime

Windmill, true the results could differ with the cathedral vs square ports. Id be interested to know your results, though I hope to have mine ready soon, it would tell me if I made the right choice. How many rpm's are you turning at the shift and traps?

on motor im turn it 6700 on motor and 6900 on nos. I think it about 7000 to 7100 at finish line on nos,, not sure on motor but I do have 4.56 gears... but I leave on footbrake about 2300 to 2400.. but will flash about 4700 on converter..thats why I think I have 60fts like 1.44 on motor and 1.29 on nos. I can tell you more on motor if you want the info

Nickelndime

^ Sure you can pm the info if you want.

There's a used Super Vic local to me that I inquired about when it was recommended by BTR. It can be bought for the price of a new Vic Jr. Going against everyones advice (even my own), I may jump on the opportunity to get a Super victor at that price.

This is a new build so I have no data with the Jr to compare but if worse case scenario is no gains with the Super then I'm ok with it. Eventually i would like to test back to back myself

I'm reviving my own thread because I will be swapping out the super victor for a Victor junior this weekend. I have made about 20 passes the last two weekends getting the super vic combo dialed in.

The car is now deadly consistent, however it took alot of carb tuning to get dialed in (mostly stumble on initial hit) with the big super vic intake. I think the the Vic jr would tune a lil easier with the improved signal as well as picking up E.T. from being a little more crisp down low... at least I'm hoping.

The new Vic jr is going on this week and I'll report back with comparisons/ results for those interested.

I have not had a LS3 Super Vic in my hands, but I have looked over the cathedral Super Vic pretty close. Brian Tooley told me that the square port Super Vic is a much larger intake than the cathedral Super Vic. And, most of the disappointing results I have seen from the Super Vic have been on square port applications, so it will be interesting to see how you do this weekend.

Rectangle potlrt vic jnr is the same as cathedral super vic. Rectangle super vic is bigger again, almost same size as a mast 2 piece

Nickelndime

Those ls3 intake/ heads can move a ton of air. Pretty significant difference in the two cathedral victors, not only height but runner size. I know most have seen both but here's a pic anyway.

Just got my 418CI L92 motor started. It's got a 4150 biggest 4150 carb I oucld buy from AED. It's a nitrous deal so I'm looking for plenum volume.

My 6.2 motor ran low 5.60's with cathedral port heads A 2-stage nitrous set-up and a Vic Jr. We'll see if the new set-up works better.

onefast84

Interested too. I switched from a gmpp to a super vic. It is some what sluggish on the low end.

Nickelndime

Alright, I made 6 passes with the Vic jr yesterday. I swapped intakes and changed nothing else. The Victor jr was .03 slower in the 60 ft and about .05 slower in the 1/8 mile as well as down 1 mph.
