anyone have anything to do with this?

how well does it work? and most of all, DOES it even work?

 

I dont think an air horn would work well with the tbi. The injector pod sits smack dab in the middle and blocks the flow. Better for carb use only.

 

JEG's & Summit Racing sell the same part, just made by someone else. IMO there better & cheaper than the one you were looking at.

 

They are better suited for carb. It really shrounds the side of the TBI and that is where we get all of our air. With that in place the air has to come from above the injector pod that is smack dab in the way.

 

Hypertech is the other company. They say there for trucks only. It may fit with a cowl hood though? Don't know about HP, I've never seen anyone with one.

 

From the looks of it a simple Open Element will work LOADS better than that. Do the ultimate TBI mods and you just gained the same power if not more, AND saved some $$ (IMHO)

Isn't the Hypertech piece the one used recently in Chevy High Performance and Car Craft on those TBI trucks of theirs that put 8 HP and 8 lb/ft across the entire RPM band?

 

Yea it is. I think they sadi they saw 5hp gain on their 305 TBI truck project. I can't say though if their numbers are a plug or not for hypertech. Their 5hp gain could have also been a result of something else.

 

Check out the Car Craft article. They clearly state how they where unimpressed with it and didn't think it had a chance, but were suprised by the 8 HP and 8 lb/ft across the entire band. . . however they do have a 350 in theirs.

. . . but come to think of it, you NEVER see a car mag criticize a product. So why do I even buy them if they won't give me an honest write up on a product?

 

I will have to check that out. They used one on the CHP buoldup of a work truck. They were skeptical as well but I geuss they say a few ponies. You are right though and they would never critisize a mag sponsers product. HA! They need to hire one of us

 

LOL, I wonder what those interviews would look like?

I was jsut gonna post asking about this. I saw it in the new car craft and it supposebly did 8 horses, But it does look lik eit would raise the air filter up higher so i think when i get my cowl hood i may give it a shot. Seems liek it could help more than the spacer would.

"We instantly dubbed it the " soup bowl" and laughed that this could acctually accomplish a power gain. Our laughter turned to amazement when the soup bowl pumped the power up across the entire power band, adding 8 lb ft of torque at the peak and 8 hp! The key to this little piece is that throttle body injectors dotn breathe from the top becasue the injectors are in the way. Instead they breathe from the sides. The soup bowl merely creates a gentler radius that enhances lateral air flow, thus making more power." righ tform the cc article

It sounds to me like it gives it a some what swirling affect going into the bores. It also says in here that headers without additional fuel will actually loose power so now i'm super confused

 

Why so confused? That's a known fact. If my memory serves me correctly, when they installed the headers w/o any other changes, they lost 1 HP and gained like 15 lb/ft or something like that. But when they added the Hypercrap chip they jumped up 20 HP and 40 lb/ft or something crazy like that, due to the changes in timing and the fuel curve. They also mentioned that if they had driven around much longer at those lean conditions that they would have scorched the piston rings or something to that effect.

I had the same effect when I first put on my headers as well. Although I noticed a slight improvement, I was at first highly disappointed until I put on the VAFPR and pumped it up. I then promptly failed my first emissions test, but I was happy none the less. I detuned it some in order to pass, and now I'm in the middle of an engine swap, so we'll see what happens when that's done.

 

Gunny,
Mebbe ya need to re-read the article. The lean conditions existed before the Hypertech chip install. That's when they mentioned the WOT and mebbe melting a piston. As far as being a shill for the advertisers, I don't think they would use a dyno and mention the dyno shop's name if they were lying about the results. Has anyone thought that maybe the products actually do work? I'm not trying to flame anyone here, but I'd like to give a little credit where it's due. Dyno numbers don't lie.
My two cent rant...

Cheers,

i gotta agree with 357. I figure when i get my cowl hood here shortly and get it painted i might just have to order one. Worth a shot.
