Can I install an exhaust tip on my stock engine without it altering the exhaust flow? I don't mean a weld-on but a simple clamp-on, to pretty it up a bit. Will it technically void the warranty or is anything muffler-back ok? Thanks

On the '08s. What separates, if anything, the 6.7 Cummins from the 6.6 Duramax and 6.4 PSD, in regards to tailpipe design? If you're unfamiliar, the 6.7 is a straight, no holes, single slant-cut tip. The 6.4 has a dual pipe thing, like something you'd make fancy shapes in potatos with, and...

Ok, I need shocks for my new air ride I'm making. Fronts only for now. I need 20.25" ride height, but available to go from 15.25" under compression to 25.25" under rebound. Is there such a thing? Is there a range of lengths shocks come in? Is there a certain ride height to allow travel each...

So, pardon me if this has been posted already but I think Pass Time on Speed would be a cool little show for some diesel drag'ers to run on. Pinks this, Pinks that, at least you don't lose your ride :) That's all! Nick

Well, sadly, I sold my '06 5.9L Cummins, so up for sale is my Smarty CR. This will fit 2003-2007 trucks with the 5.9L. The Smarty itself says "S04" but has a model number sticker stating it is an S06B06000199 and HAVE used it on my '06. It is almost 2 years old. It comes with all the...

Does anyone know what the towing capacity is for a 2006 2500 Megacab? 4x4, CTD, 6-speed, SLT HD, 3.73s, stock tires, stock receiver and hitch, 7100 pounds empty with half a tank and myself. GVWR is 9000. Thanks

Anyone seen the July 8 Lug issue with the "450" on the cover, lower left corner? What's the deal with this thing? It's an '03-'05 (???) F-250 with a dual wheel conversion and dually bed, with an '06 front end and '08 "F-450" badges? Isn't that like a ricer putting "Type R" badges on a...

Do twins usually spool faster or slower than a stock HX single? A twin-turboed Dodge owner on another site complained the new Ford 6.4 diesel spools slowly due to the twins. I asked him if his twins spool slow in his '04 Dodge. I know one of the points is to hold higher HP with lower EGTs...

Anyone running a Smarty and upgraded turbo from stock at 5000+ foot altitude? What is it and how much power are you making? A larger turbo means a clutch and fueling upgrades, i.e. FASS or other pump so right now I am only dreaming ;) My truck is very smoky on the #9 Smarty setting at...

So, who is right around 500 hp and 1000 lb/ft? I am curious what the cost was to get there. I am not talking about clutches, VB's or other tranny work, gauges, etc. Just engine mods. Not nitrous either. I know, I know, picky me! So whoever owns what, Cummins, PSD, Duramax, etc. List your...

I didn't want to race you, Mr. red F-250 6.0. You were behind me most the time (since the right lane traffic was faster) on 287 west before the exit to 287 north. Was it fun speeding up to pass me then slamming on your brakes as you tailgated the people in front of you? :clap: By the way...

How do these all compare? I know they are difficult to try head to head due to running on different brand engines. I have a CR Smarty. What I am curious about it max claimed HP out of each, timing increases, and EGT decreases. I know the EFI and SCT have additional things like guages and...

Some dude wanted to play with me today on I-25 going south toward Thornton, exited Thornton Parkway about 5:15 pm tonight. You were driving a dark blue or black (it was overcast and rainy) F-350 CC, dual exhaust, 6" tips, with some smoke and a "Ford-You Can't Piss On What You Can't Catch"...

I posted this on TDS without any replies so I thought I would ask here also! So all this SCT stuff has me wondering how it works. I'm used to plug-in modules and Smarty for Dodges, but not any of the SCT stuff. Can anyone share how the programming works, is it a 'load and forget' like the...

The VT is the commercial downrated version, correct? The "Powerstroke V8" is the pickup version. What differentiates them besides a catchy name (that Cummins doesn't need :hehe: )? Nick

So I will PROBABLY stop at 550-600 hp. So what clutch should I get for this? I haven't had a chance to call Peter at South Bend for my G56. I am thinking of the strapped Dual Disk. Do it right, do it once, correct? I think I will call tomorrow but don't want to take my Smarty past #5 until...

I am building 4-corner, 4-link custom air ride :woohoo: . The fronts are about done, and I have a certain height to work with for installing shocks. I don't want a super fancy shock, just something better than stock. The mounting points, center to center, are decreased, but the lift is going...

So, the title says it all, only performance mod on my otherwise stock truck, but it is straight piped. I think an AFE II is next. Anyway, I love it. I am running #5 right now but have to watch the RPMs so I don't slip the clutch. Nick

So I screwed up my air ride :( I am working on the fronts, going to get 3" total, 2" lift and 1" level. I will lift the rear 2" but only have the front mostly done. So, I screwed it up by not adding enough of a spacer to get my 3", only 1.25". So, if it levels the front by 1.25" can I add...

Ok, so this is like a Stage 1, no tube, just filter and mount. Anyone have it? If so, how does it compare to an AFE if you have/have had one of those. http://www.quadzillapower.com/products/intake.html Nick
