What is the TVS?

 

why is it always this way?
a post about the 122 and the guy sturring up the pot is the one who also says "I don't know what the difference of the 122H is"

lol

More Than Zero

 

Good catch....hence the use of the term...dumb ***!

 

good question, the TVS is the replacment for the tech in the MP112 and 122. it is used in the new ZR1 I believe.

and thanks for a good, to the point question.

More Than Zero

 

This forum is great, did a search and found several conversations on the TVS too. Thank you again M_T_O for your answer.

 

Wow... I wasn't aware of the differences between an m122 and an m122h. Big f'n deal. Im not one of the geniuses in this thread who thinks that high rwhp = throttle response.

Callaway must a higher standard in their delivered product. Through all of your childish name calling you still haven't explained why they would shy away from selling a product they could make more money on.

Keep calling names and editing quotes... it really makes you look SO cool

 

OK...................

I started this thread, one as a light hearted discussion about the new maggie and two so that I may get some info from people who have more knowledge than I on this topic.

SurfnSun (wow where to begin ) You seem to have taken some kind of offence to something I said and turned this into a forum battle thank you for that . "geniuses" I don't think so but I do know when to joke and laugh and have a fun discussion with fun people who are all here to share information. Stop taking yourself so serious life is tooooooo short and before you know it you will be thought of as an a$$hole and know one will want you in there club Oh wait.......nevermind anyway loosen up dude before you have a heart attack

PS Callaway is a great company know one is talking smack about them.....its ok (soft voice) its ok (soft voice) Callaway is the best honey (really soft voice)

 

Hopefully all the BS in this thread has settled?

I'm still looking for the real reason the 122 is a bad idea on the 5.7L. Does anyone have a dyno graph or any real world data as to what undesirable throttle response means?

 

There is absolutely no problem running a 122 on a Vette.Truthfully the 112 shouldn't even be offered for the 5.7L because it's too damn small. The 122 give alittle more hp and NO tuning problems.

With Callaway you are paying for a name because your definitely not paying for a high HP setup I've dyno'd there high hp cars,there dyno must be wayyyyyy off.

 

I have a MP112, and they are defently to small IMO and should be replaced with the MP122.
The only problem with running a MP122 is, I don't think there is a kit for the C5. You can probably make it wok, but you will more than likley have to notch the rear brace under the hood to clear the rear belt.

 

They probably have a bunch of 112's they need to unload.

The 122 will be much better, even on a stock LS1. Go for it.

 

My financial situation is still unstable so I'm only doing research at this point but.......

I spoke to Callaway

Undesirable Throttle response on 5.7L = Slightly sluggish response measured in milliseconds off idle. No biggie if you ask me, as you begin to do engine mods e.g. heads, cam, possibly stroke you will improve this.

@10psi the 122 is well with in its efficiency range there for is more desirable for those looking for a little growth potential.

@10psi the 112 is really beginning to heat up and is reaching beyond its efficiency range

Does anyone have a dyno graph of the 122 on a 5.7L?

 

Its quite simple really..
When we did back to back testing on the KB 2.6 and the KB 2.8, we had the same problem.

Basically the 112 and the 122 relate to the size of the blower. The larger blower will actually move air slightly slower at the lower rpm's due to the rotors and internal cavity. This directly relates to "Throttle Response". The smaller blower can compress the air faster, hence giving you quicker response. It almost the exact same theory as a turbo setup. The smaller setup will hit harder and run out of steam faster, where the larger will hit slightly softer, but carry through the RPM band.

Callaway's statement is mearly a marketing strategy. They know regardless of how large the blower is, THEIR general clientel relates the blowers success to how HARD they feel it in the seat.

Although the 122 is still WAY to small for our cars, its significantly better than the 112.

Case in point: With EVERYTHING being the exact same, inclusing the pulley size (only swapping the the blower head unit) I gained 3psi of boost from going from the 2.6 to the 2.8KB. In order to get the same boost as the 2.6, I had to run a larger pulley. This slowed down the blower. By doing so, my bottom end was slightly softer.. BUT....One I increased the boost, the efficiency of the 2.8 was superior over the 2.6.
Not because the the 2.8 is better than the 2.6, but because the 2.8 was better suited for my 400+cid motor.

Does that answer your question?

 

Oops, I didnt read your last post..

At least you know I was correct..

 

No problem American I still have the pm you sent me some time ago, KB may still be an option for me depending on my $ situation.

Thanks for the input like I said I'm only doing research right now

 

No problem, I wasnt trying to push one blower over another..Just answer your question as best as possible.

 

No problem American I do still like the KB and I have alot of friends with Cobras saying go for the KB

 

down

 

Like this?

 

i wonder what the max hp rating and max boost is for the m122 or m122h?
