Going to be picking this up soon. As a newb I must ask.

What do I need with it? It comes with 2 pullys. 3..0 and 2.8.

Im running on the stock tune, so of course I need the tune.

1500 for tvs
300 for tune

Im trying to get a full price total of everything im gonna need, shed some light tvs guys.

 

dang. not bad man. i would suggest some coolong mods too man lol

 

Have a heat exchanger, going to put on a dual pass too.

How u been bro? Saw you got a new engine

 

60# injectors and a harness will get you running, but if you plan to run that 2.8 I would just get 80's, especially since they are similar in price.

Also what is your exhaust setup?

And you may want to look into some more octane...

 

Theres already a thread about this...

https://www.cobaltss.net/forums/adva...ow-faq-184037/


Stick with the 3.0 pulley until you get cooling mods, perferably, meth injection. Exhaust and traction mods arent a must but if you want good numbers/power and be able to put it to a ground, then i suggest those as well.

 

dont forget a better exhaust system. tvs brings in a lot more air...need an efficient way of getting rid of it

 

I have a header, intake, 2.5 exhaust and heat exchanger.

I need 60's, dual pass, and a tune then, and I should be set, according to the list in that thread.

about 1900 bucks total, not too bad.

 

Good link Srt. I forgot about that.

OP go with the 80# injectors over the 60's

 

i agree, 80's over 60's will help you in the long run, especially when you drop to 2.8.

 

And dont forget you will have to mod your maf sensor. Picture makes it worse then it was but heres what mine looked like...

 

Definitely 80s as stated by those above. Looks like you either have, or know the rest of the needed mods. Good luck with the tvs!

 

Oh yeah, mod your MAP sensor like the pic above

 

is it MAP or MAF? i always get them confused..lol.

 

Its MAP lol MAF is in the intake tube

 

been good man. and yea i finally get the motor this week so hopefully by next week i can get the cobalt runnning agaiin. ill be taking my broken motor apart to see what all the demage was...maybe sell the good parts, not sure yet. and yea man jump on that tvs setup sounds like a good deal man. ill say get some 80s for when you go lower on pulley...whos tuning you anyways?

 

Its gonna be alongg time before I get the tvs on the balt, just in the buying stage at the moment.

 

If you don't have dual already, skip it and go single. Don't forget option b. Might need to upgrade your h/e depending on what you got. Love my Griff.

 

Just as a heads up the TVS is absolutely worthless if you can't provide the octane that it needs. All the cooling mods in the world aren't going to allow you to run more timing without detonation. Even on "medium sized" pulleys such as a 2.9, you are going to need to run methanol injection, c16, e85, or some type of high octane fuel to make any decent power. People without good gas are producing the same numbers or slightly higher as m62 guys are which is sad but true. People with e85 or other high octane fuels / injections are making upwards of 350+ whp.

If you don't want to use meth and can't have e85 for whatever reason then stay away from the tvs as you will not like your results.

 

This is not 100% accurate.

There have been plenty of people on this site to break 300whp with the TVS on pump gas even w/o the use of meth. Its all about having a good tune and the proper supporting mods to handle the airflow the TVS produces.

Now, if you are going for big power E85, meth, or race gas is where its at.

 

I never said NO ONE can produce more then exactly 300whp without meth or higher octane fuels. If you take your time and re-read my post I said and I quote "People without good gas are producing the same numbers or slightly higher as m62 guys are which is sad but true".

That satement is exactly true. Take any amazing tuner and give him a tvs with a small pulley and 91 octane and tell me how much timing he can get out of it. Even with 93, it's not much more.

The TVS Loves timing and LOVES octane more then anything else! These cars will just SCREAM when on race gas, e85, or lots of meth. HOWEVER when you do not have access to any of these, the TVS is not nearly as powerful.

I have seen dynos as low as 280s with the tvs and as high as 320ish without high octane gas. That is pretty well within what I said.

Can some people produce above 300whp amounts on the tvs without high octane fuels, yes, and I have and currently am doing so. Is it smarter to spray meth or run e85 / race gas to gain 50whp, absolutely.

 

I run race gas, and I agree.

I took time to read your post. I never claimed you said you "can't" produce over 300whp on the TVS w/o meth. I just want the OP to know you can. I've been around this platform a long time. You don't need to explain to me what the TVS needs to make power. I wanted to clarify your original post for the OP that is all.

 

No worries then, I was just simply backing up what I was stating because it is true as you know. YES people can make decent numbers without meth/e85/race gas however it is also VERY common for people to put a decent amount of money into a TVS setup to then realize they can only run 12-15 degrees of timing and are only making 315ish whp and are not happy.

I have seen m62 e85 cars put out 300whp and I have seen tvs 91-93 octane cars put out 280-320.

It's all in the gas and the tuner, make sure you have an amazing tuner.

staged07ss - I have read a lot of your posts and I know you know your ****, I wasn't arguing with you, just stating facts from what I have seen over the years.

 

Its all good man, and you just made a lot of valid points

 

Thanks. I am running a tvs currently and have been through all sorts of things with it. I finally decided to bite the bullet though and pick up a set of idc 1000's and toss them in. This way I will be able to rev out as far as I would like on the 2.9 and not have to worry. Then when I have that all dialed in and I want to push it further I will grab a return style fuel system (will probably do this while I am still on the 2.9) and a new in tank fuel pump. I'm not sure what our pumps can handle, but from what area47 has said I believe he has changed his.

 

Yeah, I can't remember if he upgraded or not, but I'm leaning towards that he did.
