Lets talk about BOV's....Tial Q/50 and Big Red???
 

I have a Novi and it is really quiet. I would like a louder BOV, but I don't know to much about them, so if you guys could give me some knowledge on them , that would be great! I want a loud one that sounds like a 747 taking off, what is the best one to go with, I know the Big Reds are over $400 and Tials are $250ish. what would be a good BOV for my setup, 10lbs now but 14ish next year when I do the bottom end. Also is the bov going to add performance, or is it just to have a better sound? Thanks in advance for your input?

dude im in the same boat. have a big red on my z now and had a tial 50 on my trans am. could have sworn the tial was much louder but could have just been the placement. Just got a ysi set up going back and fourth which 1 to put on. Also as far i know bov's dont add performance, except if you have a cheap 1 thats leaking off boost which would make you lose power

Big Red is almost double the cost, so if there is not a performance gain, why would someone pay that amount of $$$. Also Doug at ECS stated I would be fine with a Tial 50 and a 10lb spring witch he said is obnoxiously loud, I wish I could hear what that sounds like. How do you pick a spring, does it go with what boost your at?

I'm trying to find a used one, but that seems hard to find as people hold on to these like RPM transmissions. I looked for a month to find a used level 5 or 6 and no bites so I bought a new one. As soon as I got the trans, 2 were for sale on the forum. The same thing is probably going to happen with this BOV. What springs are most of you running at 10lbs, and how loud is it?

Does it matter where the bov is placed?

i think it does. on my ta i was running a t trim with a tial 50, the bov was mounted on the top passenger side and it sounded loud as $hit. in my vette the big red is mounted low in the center by the oil pan kinda. seems not as loud, could also just be that my exhaust is so loud dont hear it. both cars are at around 11 lbs boost also. guna stick with my procharger valve on the ysi, hopefully at 17lbs. it screams:yesnod: . .btw was talking to mike at ecs today he says hands down big red is the loudest

& big reds expensive cause people use that in highhhh hp and boost applications. suppossed to hold a huge amount

Go with Turbosmart! I have seen many Tial's have issues. Also call both of there customer service numbers if Tial happens to pick up consider yourself lucky. Turbosmart has some great people working there and back up there product 100%

If you want loud I have a HKS one from subie I am dumping :)

I may be interested if it fits my application, please PM me your contact info!

Bro I have a tial 50mm and it's loud as ****! I'm not too far away let me know next time you're in Chicago I'll let you hear it

Blitz,

I just replaced the bosch bov that comes with the Novi kits with a tial 50 over the weekend. I originally had the tial located in the top charge pipe righ in front of the MAF. It was messing with the tune so we put the bosch back in the stock position.

I relocated the tial down to where the 2 45* rubber elbows meet after the IC. I removed the air pump so it fit perfectly in there. From my understanding its better to have the bov immediately after the IC for it to work effectively. Could be wrong but that's what I have read.

I also read that the tial needs to have the 3 psi spring in it so I bought one off of ebay to replace the spring that was already in it.

I went and drove the car for a little while this weekend after I swapped out the springs and let me tell you that it's continiously loud. What I mean by that is that it's releasing air at all times when just cruising then closes up when a little throttle is applied. I imagine it's doing this b/c of the 3 lb sping that's in it. I can see that it may get a little annoying after a while though. I guess it depends on what spring you want to use.

The noise level of the Tial is completely spring pressure related. You can have a Tial that is hard to hear at all, or obnoxiously loud.

We are 160 miles away, we should meet in the middle sometime, as I would like to hear a 3lb spring, Doug (ECS) said 3 was loud and 10lb spring is crazy, I was thinking about a 5 or 7lbs. Also you bought yours new, where from and how much $$$,? Did you have to have that flange welded?

I'll be up in Indy this Friday back at Norris to see if the spring swap helped out my problem. Come by and check it out for yourself. :thumbs:

I actually bought the Tial used from a member on here. I think I paid around $200 shipped for it.

I'd say start monitoring this board and ls1tech 4 sale sections. There was actually a lot of bovs for sale about 3 months ago.

What I ended up doing was buying a 3"x6" aluminum pipe from A&A. Took that and the flange to a local machine shop and had it welded. Cost about $75 total for the parts and welding.

I am going to by a 3x6 pipe so when I do buy a new BOV, I can take the flange and pipe and get it welded up. Then I can just swap the BOV's with no down time on the car, Do you like the 3lb spring? I forgot that you will hear it all the time cruising, maybe I will have to re-think about a 5 or 7lb spring. I would like to come and see and hear your car, but Norris is 160 miles for me and I have to work nights this weekend.

the 3 lb spring is loud for sure. Like I said, it maybe awesome for a bit but could get real annoying fast. I don't seem to mind it though. Ask me that question about a month later. I may have a different opinion. lol

Car sounds NICE! What pound spring is that? And yes I'm 30min from Chicago, we will have to hook up for lunch and that little race!:D

TurboX's RFL

RFL = Real F'n Loud

Hey Kid, what bov do you have, I'm pretty sure I'm going to go with a Tial Q or 50 with a 5lb spring!

I run the Vortech Mondo. Its like the enclosed race from Procharger.

Here is a vid.

I'm running the "Big Red" and my car sounds just like a 747. On the other hand my friend Tim is running the Tial 50mm and his sound just like mine does, I can't tell the difference. IMO, they will both do what you want them to do, and also sound awesome. Good luck with your choice. I could post a video of the sound if you like??:thumbs:

Not to Hijack but where would I place it on an A&A kit? Same spot as the turbosmart?

Yes could you please post a video! Also do you know why the big red is almost double the coat of a Tial, if they do the same thing and sound the same, just wondering?

yup :thumbs:

Don't know why they are priced so differently.:(
Here is where mine is located also. It's right in the middle of the charge pipe.

I edited my first reply and added the videos there:thumbs:

After watching those vids...that's exactly what mine now sounds like with the tial on it.

That sounds SWEEEEET!!!!!:cheers: Music to my ears!

Thanks bro

TurboX's RFL, it's loud. When your cruising you can hear it pretty far away, but it's not annoying in the car.

Personally I like easyvette's rattlesnake :D

Can someone tell me the difference between the Tial 50, Q, and Sport?

And why can't they give you a flange that is welded to a 3x6 inch pipe? It's a pain in the a$$ to have to find a shop and have it welded!

I just got off the phone with Brute Speed and they suggested the ATI Procharger Bullet Valve. Does anyone have this on there car? I did a search on you tube and the forum, and nothing came up to hear a video clip. I guess this valve is for 750hp and below and he said it would work well for my application. This is a new product that came out about a year ago!

Looking at the ATI Procharger Bullet Valve as well. On ATI's site it cost as much as you can get a big red valve from other venders. Wonder if its better for the lower 600 horse power guys.

:iagree:

I used to run a Tail a few years ago and no where near as nice a piece as the mondo !

I wouldnt touch the mondo with a 5' stick... Tial Q with 3lb spring FTW! :thumbs:

What supporting vendors sell the Tial Q on the forum?

tial sounds like a street sweeper all the time with a 3lb spring ;)

I have a Tial Q with a 6lb spring and A4, and it does not seem that loud, is the 3lb spring louder?

I put mine here.

Do you have a better shot from the driver's side? I'm guessing your speed density, no maf.

S/D no maf. I have another pic somewhere but not online.

I have a ttix car with hks ssq bov's...they sound pretty cool.got a few funny reactions too when I taped "duck calls" to them hahaha

3lb will be open all the time. I had this setup and it literally just "wooshes" continously and got annoying real quick. I decided to look at what the racers were using and the Vortech Mondo seemed to be the popular choice and has worked great so far without the noise.

It is louder but it keeps IAT's lower by a few degrees. If noise doesnt bother you, this is the way to go.

I know this is a super old thread but what #spring comes with the Tial Q BOV in your Blacked out 1500 kit? Could I change it to a "louder" spring? How do you go about getting a spring and is the install easy? Thanks Doug.

Springs are either lighter, or heavier, not louder. A softer spring will allow it to pop off sooner, possibly collapsing sooner than desired, bleeding off the pressurized air going into motor. Stiffer spring will obviously require more pressure to open, or possibly not at all.

Big red is the loudest I ever owned, then again I'm running an f1x. Worth the money though

Dammit I just helped bump an old thread

i went with one tial 50 with the supercharger spring and it was placed above the crank where the piping is. this was really really loud for me. now my friend who has an A&A kit put a tial 50 where the stock bypass valve is on the kit and it is twice as loud as mine, sounds like a jet engine.

i went to 3 bar map and decided to add another tial 50. this was the best decision i could have ever made. The location of it is on my charge pipe before the throttle body. the only time i hear it is when i am blowing off some serious boost. i will be up in indy for SCT in may if you would like to hear the car better.
