Vig 3600 vs. ss4000 My friend has a Vette with a Vig 3600 stall, GT11 cam, intake/exhaust, 3.73 gear, and is pretty disappointed in his times. He is on a slick. He cuts 1.80's 60ft's, 12.0 1/4 at 116. I am not familiar with vig converters as I always use and recommend yanks, but how much time if anything will he cut in the 60 ft using the ss4000 vs the vig 3600? I cut low 1.60's 60ft with my 01 Camaro with a stock engine and the ss4000 3.42 gear. If any relevance, he makes 435 RWHP (forgot tq), I make 320 RWHP 321 TQ, and my car weighs about 500 lbs more.
He's just trying to justify the price of the converter/install vs performance. Comparing it to my car, his has more power, lighter, and a bigger gear, I think he should be able to cut a 1.5 60ft and run an 11.50, but like I said, I am not familiar with vig and by no means an expert, and maybe someone here has done that swap.

Maybe his Vig isn't setup/spec'd right.....It is a very similar converter to a Yank SS line and they should perform on par with each other. That being said, he won't go wrong getting an SS4k.

A vig should 60' just as hard, in some cases slightly harder, than an equal size yank.. But it will lack the efficiency/mph.
He either needs to get his converter checked out or buy a new one.
He should be cutting high 1.6s at worst with that converter. Yank 4000 should net him low 1.5s.
Even if spends 700$, will be well worth it imo.
***make sure thereisnt another problem before pulling the converter. Timing in low rpms/traction/etc.

Thanks guys. I'm pretty sure the motor and tune are ok since it makes power. I think I'm going to suggest the ss4000 for him and see where it goes. Driving his car, it feels ALOT tighter than my car, I always thought that was because his was a 3600 and he has the 3.73 gear.
Do you think we will have to re-tune for the upgraded stall?

Why? Stock suspension. It raised the tires about a foot and then unloaded causing it to spin horribly. With suspension it would have cut mid-high 1.4s consistently.
It wasn't as efficient as a Yank, but it 60' just as hard as any Yank I have seen.
It was a 4000. Vigs are known to hit very hard out of the hole but lack efficiency up top.

We talked about a cam swap and tuning changes, but I strongly suggested the converter since even as a bolt-on car it should 60 better assuming nothing else is wrong.
I told him about my fathers 01 Z/28 H/C/I, SS4000/3.42 and 275/60 that goes low 1.5's and best of a 1.48 on HP @ 3600ish #'s. The car makes 440ish rwhp.

I spoke to your buddy Nick and suggested the SS4000. I have always had the best luck with 60ft as well as driveability with Yank.

When we originally talked about converters, I told him to go with a Yank, but Powerhouse (Where he originally went to for work) told them they wouldn't warranty a yank converter, thus he went with the Vig. And, at the time, he wanted a small converter because he liked the drivability over performance (that has since changed). Needless to say, when I drive his car, the converter seems tight, almost like stock. He drives my car he thinks somethings wrong with it, lol.
The reason i was worried about the cam is we picked that cam because he wanted to stay stock manifolds/intake ect. and wanted to sound almost stock. That has now changed so I think he would benefit from a better cam as well. Unfortunately, I don't think he's going to see a considerable gain from a cam to justify the swap. He just wants the better bang for the buck basically.
Long and the short of it, after we talked last night, he's going to justify a converter change cause like I said, if he can get his 60ft down to around mine or better, he should see a significant increase in 1/4 mile performance. If not, I'll hear about it later from his Wife (My Wife's sister).
Again, thanks for everybody's help, I may resurrect this thread next year after the change to let everyone else know the difference between the swap. Maybe this will help out other people looking to do the same swap.

I had an old school Yank ST3500 back in the day & then went to A Vig 3800 & my 60fts were exactly the same. Splain that? I then went to the SS4000 from the VIG 3800 & gained about 1 1/2 10th in the 60'..These converters are way different...I went back to a Vig 3500 from the SS4000 so I can get consistent 60' because the SS4000 hit to hard to be consistent while bracket racing.

my 98 corvette
has 390 hp/368tq on mustang dyno.
373 gears, cam,ls6 heads and manifold,headers.
i had yank ss3600 converter = best 60 was 1.64 and 11.46 d.a. corrected. now i have yank ss4000 and same set-up.i have a 60 ft of 1.53 at 11.46 = 11.19 d.a. corrected.

Larry, I appreciate you talking to him, he was really grateful that you spent the time helping him out. I advised he call you because all my friends talk nothing but good things about you upon or garage drinking nights. I'm friends with Bill Whalen, John McPartlin and a few other guys who have delt with you. I have not met you personally, but never heard a bad comment about your knowledge.

I just wanted to see him make the correct moves first and the converter is just that. The Vig 3600 should feel rather loose and if it doesn't it was not built properly or maybe never re-stalled as he was told. The nice thing about the Yank SS series is that it drives well IMO for a loose stall, hits hard and is efficient on the big end. I tested a few converter from Yank when I was looking at going N/A.. PT4000, PT4400 and went back to the SS4000 which worked the best..more MPH and best 60ft.
The LPE cams though tame as far as sound goes and their great driveability do perform very well. I'm sure he could see more from the car with a different cam and combined with a larger stall could give up a little low end associated with larger cams.
glad to help and hear most people still like me after all these years
