Search for my FAQ on the TVS. The stock 80mm TVS pulley will out do a 2.5 on the m62.

^ahhhh omg did you read the entire thread? i just went over this with area47. I said, like many others have stated, if you run the smallest pulley (2.75 or 2.6 i think) on an otherwise stock motor, you are taking a big risk bc our head cant flow that much air so ur just cramming it into your intake manifold.

The TVS would be a poor choice if you were aiming for 350WHP. There are dozens of people running them and they usually dyno around 300WHP. Sure it's very possible to do higher but it doesn't make sense to do a build that averages ~300 and shoot for 350. a turbo set would be the way to go for hitting that power.

i think its unrealistic to say the average is around 300whp when pretty much everyone has been above that, I'd say 300whp is the minimum if your doing things right, mine should be well over that the next time its dynoed
^lol i completely agree with you. I think the tvs is good for 400 if you get a ported head on its smallest pulley. now to get 400 whp on a turbo (on our 2.0 liter motors) youre going to have some serious lag.
For those of you with the TVS... What was your best dyno numbers and what type of dyno was it on? If you could supply us with some of your upgrades too that would be great. Also, how is your transmission doing now that you are putting way more power down. Did GM Make a good enough transmission for us to be putting down 350-400 hp?
TVS = cheaper than a full turbo set up, and cheaper than the twin-charge kit.
My goals are around 300whp. TVS = perfect for me. Less of a pain in my ass on installing and tuning.
I would love to see someone max out the stock 2.0 on the TVS... i have no intention of ever going past 320.... i'm just curious

Yes, completely unrealistic. Strange that you dyno'd 278WHP though. Looks like you misposted or maybe went to the dyno twice and followed the 278 with a 282? Man, you guys got me. I'm just being completely unrealistic with my claims. Let me guess, yours doesn't count because it needs to be tuned? Here's info for those that don't want to search:
12. Rodimus_Prime 282whp, 254wtw Verified I, H, DP, E, T, DU, 60s, 80mm, WI, HE, TVS
8. lsjwannabe 312 whp 267 wtq Verified 2.75, 60s, DU, I, TB, RS, H, E, CD, T, TVS
15. drycell1218 276 whp, 237 wtq Verified Mustang Dyno I, H, DP, E, 60s, TB, TVS
I think I'm the only one who is being realistic here.
I"m not trying to sell turbos, I'm trying to give honest information. Something that seems to offend people around here. I didn't recommend ZZP or a ZZP turbo. He can build he own, buy another brand or buy ZZP. Either way someone asking about 350WHP should be given real information. This would be telling him to expect a little over 300 to the wheels with a TVS unless he does a lot more to the car. Or he can run a turbo in which case it's not that difficult to hit 350WHP.

Is this thread about Zooomer's experience tuning a TVS? No. It's about a guy who's asking about mods and someone who stated they would be happy with over 350WHP. What does my experience have anything to do with his quest? If I dyno'd 250WHP with a TVS would that add more credibility to my statements? How bout if I dyno'd 450? Neither would have any affect on the conversation. We should be discussing what a person can realisticly expect out of a car with the mods he posted and bolting a TVS on. If you guys are telling him he'll get over 350WHP and calling me our, you are lying. He won't. No one does. When someone asks how to get 350WHP how does it turn into a "you could I bet" type of conversation? It's about what people are doing with the TVS. The vendor who sells the blowers and has experience dyno'd 313WHP. I believe the highest dyno is Area47 with 342. Either way the average user is dynoing 290, 300, 320, whatever. But they are certainly not bolting the blower on and getting 350WHP+. Telling a guy asking about the part in a forum that this is realistic is dishonest information and you should be ashamed to support the spreading of false information here. It defeats the entire purpose of a message forum.
Did you make 400WHP with the TVS?

For you the TVS sounds like a good match.

1. rodimus prime had issues tuning because it is his daily driver and he didnt want to push it that hard , but area helped him fix his problem with the meth mix and he should be over 300 now.
2. the vendor/lsjwannabe made more power than area so the highest tvs dyno isnt 340+
3. Area47 made more whp than that on his race tune he just wont release the numbers.
4.The people claiming they can make 350whp on a tvs is no different than how you claim over 400whp on your happy dyno with your twincharge that has still yet to hit the track or to be released.
5. you should only post in zzp threads from now on because everytime you post the forum goes crazy, you do more damage than good with the so called help your trying to give.
if you would have worded the post different this would have been avoided.
my motor is bone stock aside from valve springs. 65k miles. if tuned right it will be fine. most people can't manage to keep an lsj with a m62 alive. they are over looking little things here and there in terms of monitoring and preventive maintance. in short. don't beat the holy **** out of it. no motor can take that abuse

i posted realistic numbers that would be seen on the street. i have done higher numbers on race gas, but that is not a realistic idea as to what it would run on the street. it is rarely on race fuel {110 or higher} so it's not worth it to me to post big numbers that i can not achieve on the street.
now. for what i intend to do with the car is road racing. a big turbo would hinder me on the smaller tracks like heartland part. hitting the apex and rolling into the throttle and having that instant torque would pull me faster from the corner than hitting the apex, waiting for the lag to subside and then rocket forward. that lag can get you the pass, or make you lose a position.
if i personally wanted huge numbers {400+} i would have gone turbo a long time ago. this is my reasoning. others may be different

You're so anti-TVS nobody would believe anything you said unless it was up around 325-350, and even then people would expect you to start selling them.
a. they didn't push it
b. it wasn't tuned
c. they had a problem
d. there's one guy who dyno'd really high but his numbers are a secret
Come one. I feel like I'm taking crazy pills here debating this. I have nothing against the TVS. It's just a supercharger. I didn't make it and don't have anything to gain or lose by talking about it. I'm just condensing information that should be transparent. If 10 people buy a part and dyno it, then the average of those dynos should be the answer to a question of "what can I expect". is this a difficult concept?
If posting a dyno numbers starts a fight I think it's the audience rather than the speaker.
