Gibson Log Headers, supposed to increase torque by 25 ft/lbs between 1600-3600 RPMs?

 

[DamnYankee]

Yow...I'm not sold on that design at all...

Just think about it: the exhaust port closest to the muffler is blowing out to the other side of the tube creating turbulant air flow - and tho each preceding cylinders before it are doing the same, the preceding cylinders who's gases are trying to escape are running in to each other. To me, its extremely inefficient.

I still think individual exhaust port tubes flowing down into a single collector down at the exhaust pipe is still the most efficient way to eliminate exhaust.

 

[Hemi Pete]

That's what I think too.

I agree. Just another way Gibson can take your money and not deliver what they advertise.

 

[MR YOON]

I wouldn't even call those headers. Collectors are short as hell. They are exhaust manifolds trying to sell as real Headers.

Some gimmicks are a little more obvious than others...

 

[AtumAnt]

Hell, I'd bet the stock logs flow better than those...

 

[06trxhemi]

agreed. but they do look good all nice and shiny. i might buy some and hang them on the wall. lol on a side note i bet they accually sell alot of them. to dumba$$es, because they are shiny.

Actually they may very well increase torque in that narrow band, which could help with towing, they will not help higher rpm h.p. though and probably will hurt above 4000rpm or so. They are very similar to the old jet boat manifolds of the 1970's, good for torque below 4000 bad for high rpm h.p.

All I have to say is this: Gibson has had almost two and a half years to make a production shorty for the hemi and this is what we get? Shame on Gibson, I hope their catbacks are at least good

Just got off the phone with gibson tech support. Said they have been working on them for 7 months and on a stock 04 hemi, 8 hp 30tq. He said on the dyno, he was dissapointed with the hp numbers but was extremely pleased and could not believe the tq numbers. I asked him if he was running a programmer when they did the dyno numbers and he said absolutely not. I guess I have to take his word even though I am extremely skeptical. Who Knows, If it produced half of the tq it may be worth it.
