Performance upgrades

Hello all!

I have a 2008 Fleetwood 34B Fiesta with a Workhorse 8.1 and Allison trans. So far I e been happy with the performance, but recently bought a 24’ enclosed trailer to haul our family dirt bikes and quads, with hope soon to also have a four door Polaris Razor. So what I need help with is some simple performance mods. What I’m thinking first is I need to replace the rusted out mufflers. I’m going to use the large RV Dynomax. So true duals that’s exit in front of both left and right tires. I’d also like to do the Brazel Ultra Power ECM replacement. My concern is I live in California. Can I remove my stock one and replace with the high performance one and then R&R before smog is required? I’m assuming it won’t pass smog with the new modified ECM? Also, does the Banks Cold Air intake system work, meaning add any H.P.? Any other suggestions to help with towing?
Thanks!

I have passed smog 4 times with the Ultra Power Upgrade. I don't know about the exhaust but they do a visual on mine each time.

Why not just call Brazel's and ask them?
Also, yes you could keep your old ECM and just put it in for smog.

I guess I assumed because they can’t sell in California.

I've had the UP mod for 14 yrs and have passed the smog with margin to spare. The "not legal in CA" must be a newer regulation that would cost Brazels a ton of money to qualify (and re-qualify annually?). It is not because it generates too much pollution to pass comfortably. Maybe you can have it shipped to your uncle in Arizona or Nevada or some place outside CA. Have a chat with Jon Brazel to confirm my suspicion and get his recommendation.

Not sure what that loaded trailer weight will be, but keep an eye on that hitch and check the bolts annually.

Along the same lines, according to the 2008 Fiesta brochure (link here):

GVWR: 22,000 pounds
GCWR: 26,000 pounds
Hitch rating: 5,000 pounds
Max. tongue weight: 500 pounds

Sounds as if the coach and trailer will be fully-loaded for family fun, so keep the values above in mind.

As others have said, you can find a way to get the UltraRV upgrade shipped to you by some method. It will certainly help your performance. California exhaust sniff tests need never know. If you get it you might need to take the big UltraRv sticker off the new ECM.

I've put cold air induction systems on several vehicles including 2 RV's. When drag racing I could see a very small increase in performance by looking at my time slips. I don't think I could discern a performance increase on the RV's. Certainly not enough to pay for the cost of a commercially developed system like Banks. One thing you will notice for sure with the Banks system is a big increase in intake noise when the throttle is opened.

So if the GVWR is 22,000 and the GCWR 26,000, does this mean I only have 4000 lbs of towing capacity? I can say the previous owner had the hitch reinforced heavily.

1) If the coach and its towing appliances are factory original, and
2) The coach is loaded to its GVWR, then

yes, you have 4,000 pounds horizontal towing capacity.

It is a topic of some debate here on iRV2 whether or not it's just fine/OK/legal/approved/sensible/verboten, etc. to load the coach under the GVWR and assign that weight to the max. horizontal towing load. In other words, as

horizontal towing load = GCWR -GVW

then if your coach actually weighs 21,000 pounds

horizontal towing load = 26,000 -21,000 = 5,000 pounds

which is the maximum for the hitch as it comes from the factory.

A few points:

1) Unless you have weighed the coach in loaded condition, you have no idea whether or not it is under, on or over the GVWR
2) Unless you have weighed the trailer in loaded condition and done 1), you have no idea whether or not the combination is under, on or over the GCWR
3) Although not yet discussed, axle loads should be known and kept under manufacturer's ratings- particularly the rear axle when a trailer is concerned
4) You should confirm for yourself that the hitch is suitable for the intended load, if it has been modified.

All that said, it's been my observation (from several years on iRV2) that folks are along a spectrum from "stay within the lines" to "whatever works for me," and decide how to handle these weight questions accordingly.

We can ship anywhere, we just have to abide by CA emissions laws and advise you to not use our ECM when in CA

I wondered about the Illegal in CA statement. It wasn't illegal in CA (I hope) when I had mine installed at a Workhorse Chassis Rally in 1010. Like I said before, I have passed CA smog 4 times now and I am due again this year.

Thanks for all the input everyone! I’ll be posting a separate topic shortly regarding Workhorse wheel simulators.

I just passed my CA bi-annual smog test last month. So far I haven't had a problem over many years.
