what do you guys think about your 1.0 exhaust housings?

[85_305]

I'm very close to ordering one and was curious of peoples responses to these.

My driving is *primarily* hilly driving, very steep hills. Towing/carrying tractors, towing people, recovering people offroad/on the farm, and in deep deep snow where 4x4 is a must. Seems like a 1.0 housing would be beautiful for me, right?

Any downsides? Am I going to have no more top-end power if I make this move? After I do the 1.0 I'll be doing a swamps idm and beans tunes, fyi.

Stay away from the 1.0 housing if you tow heavy loads on hilly roads.

A GOOD set of tunes on a TW style chip will have a better effect than the 1.0 housing.

You will NOT see any more power by putting the 1.0 housing on. The 1.0 housing does nothing but build boost faster and heat the engine up more because there isn't as large of an area for the exhaust to go.

^^^^ what he said said

I was doing some looking around, and apparently as long as you dont do injectors the 1.0 is fine? In fact, a lot of people have stage 1's and they say THOSE are fine with the 1.0 also?

You think I'll have egt troubles on hills with heavy loads? What if I use a Tow Tune while towing heavy... those are supposed to keep the heat down?

i have the stock 1.15 housing and stock injectors, no IC and can hit over 1250* up medium hills with 16K behind me using TW heavy tow tune. there is a guy on here named eric who has a 1.0 housing and 200/30 injectors and runs that with no IC, but he doesn't tow and is looking into water/meth kit

Heavy tow tunes ARE hotter tunes though... a regular Tow Tune will keep egt's down better. Heavy Tunes also require larger injectors...

[terryknight]

in this case tony has two tunes tow for loads up to 10ish K and heavy tow for over that hs nothing to do with injector size

the regular tow-tune is for a stockish truck... it keeps egt's down and still gives a power increase. A heavy-tow tune will give more power, but keeps egt's up. Thats the diff between the two for all tuners. Heavy Tow's are hotter tunes.

I have the 1.0 housing and tow in very hilly terrain and have yet to see over 1200* but at this time I am running a older superchip. Future plans are stage 1.5 injectors with a php tune. I really like the instant boost I get from this housing. Even running 70 or so on the flats I have about 5 psi of boost. I'm sure that my egt's will go up a little with bigger injectors but if I can keep them below 1400* I will be happy. My bigger concern is that I already make 27-28 psi boost and bigger injectors will help push boost over 35 and the turbo may not live long with that. As far as using the 1.0 housing with stock injectors I consider it the best mod that I've done.

Not so sure if i agree with that. I was under the impression that heavy tow is defuled as the more load you have the hotter it will run so they turn down the fuel to keep temps safe. Thats why heavy tow tunes are like 50 hp while reg tow tunes are like 75. And they tune the shifting properties different on heavy tow and light tow
