Quadzilla on a stock truck

Recommended Posts

So since I am in California Smog country now.  I want the truck to run the absolutely best it can.  I may be able to squeeze RV275's in it, but not much more.  Maybe a more efficient wheel in the turbo and thats that...  unless there is a ball bearing turbo that is essentially stock that could be an option.. SO the question is I have an Edge Comp now.. I am not real impressed by it as the truck seems rough on the high tunes and it smokes like a freight train on the high tunes as well...  So could the Quadzilla enable the power without the smoke?  smooth/smoother idle?  better EGT's?   etc...   I look forward to learning from this thread as I have not dug into quadzilla much yet.

I passed a lug down emissions test with 7 x .012's at 7000' altitude   rv275 will be a cake walk with a quadzilla.  

I would personally be going with 7 x .009's and a quadzilla.  that will support a bigger turbo down the road if you want it, but still be VERY clean and make good fun power on a hx35 truck.

 

here are videos

Can confirm, practically my exact setup, and I can’t get it to smoke even if I wanted :burnout:

 

FWIW, I was able to run 7x.012 SACs with a HX35 with MINIMAL smoke and a solid tune. I wouldn’t advise you do the same for a daily driven truck but just puts into perspective the tuneability vs clean power the quad is capable of.

Hopefully @IBMobile will chime in he knows smog law way better than me.  If any other Cali guys want to chime in please do.

7x.009 and an hx35 is your setup?

I think the thread got a little off topic with everyone wanting me to make more power :ahhh:  but we failed to address how much better can the quadzilla make a stock (or essentially stock RV275) truck?

I think we were pointing out just that. Although we were using examples of slightly bigger injectors then rv275s, I ran the quad and stock injectors for quite a while and it was a solid setup. We’re also pointing out that even with bigger injectors (like the 7x0.008’s I have) and similarly sized injectors will run just as clean as smaller ones. Obviously there’s a tipping point and certain size (read: large) injectors won’t be as clean but all in all MUCH cleaner then any other tuner available.

Peak power isn't what is important when you consider injectors.  Bigger injectors will give you more useable power under the curve without smoke.  

 

So a stock injectors truck with a quad at 350 hp will drive worse than a 7 x .010 injector truck at 350 hp if that makes sense.

it makes sense, but how about not pushing the stock injectors to 350hp.  I think snap test with no tuner is what I am understanding I will have to pass and it cannot smoke.  so if I put too much injector in and it smokes, it fails..

Install the tuner in a hidden fashion and they will never be the wiser. Leave the tuning on and let them go to town snap testing it.  Had @jigabop pass with his fire hose injectors recently.

 

You will be happier with bigger injectors and less duration to make the same power as smaller injectors with more duration.  From my experience better mpg as well.

Plug under the hood out of sight then one connection to the vp44 under the apps.  The smog people tools can't see anything with it.  They are none the wiser

I definitely agree with this but to be clear this has an upper limit as well as limited somewhat to what turbo you’re running and altitude. My 7x0.012’s with the little HX ran fine and pulled well but no where near as nice and clean and hard as my HX with 7x0.008 with wiretap though. Not saying you’re incorrect Nick, just making sure people get there’s a limit.

%100 correct

 

Too big is still an issue, but I would argue that there is never a reason to go smaller than 7 x .010's if you are going to be buying injectors.  I think 7 x .010's are nearly perfect for a daily driven truck.  good power while retaining ease of tuning.  Beyond 7 x .011's and you start to have to work hard at tuning to keep it running well.

same thing for a hx35.    you would only need minimal wiretap to hit the peak power a hx35 can flow air for.   

 

wiretap is REALLY good for extending fueling at high rpms, I dont like using wiretap to make up the meat under the curve.  If I had my way I would not allow wiretap under 15 psi.

 

 

I did testing with my hx35 and 7 x .009's and I needed too much wiretap for my liking.

Gotcha. 

 

I think if I had studs and didn’t mind possibly breaking things (cough @trreed cough) I would’ve gone bigger on the injectors. 

 

Weston recommended that size so I took his advice and they’ve worked great for me. I really just want a solid tow rig right now but you can definitely scoot pretty good. I’d have to double check but I believe my fueling is starting at 109 and I can’t get smoke so I’m slowly going to increase until I find the limit.

He makes nice injectors.  I really wish I could have tried a set of his injectors in my testing, but the $$ didn't work out.

 

I believe bigger injectors are able to flow more fuel more efficent IE with less smoke under the curve when at the same hp.     

 

from my testing it felt like the truck had more torque across the entire rpm range with the same smoke with the 7 x .012's compared to the 7 x .009's  if that makes sense.   

 

 

hard to explain, but think of it this way.   

 

in order to make 300 hp, 

 

small injectors need to stay open longer to inject enough fuel to hit the hp number, where as bigger injectors dont need to stay open so long to hit the same hp number.  This means your "power" can be injected at a more exact point in time in the stroke, reducing egts and smoke.

I completely understand your point and agree. In my very limited ‘testing’ compared to your extensive amount, the best way I was able to describe it was with smaller injectors you need more wiretap to get the truck moving the same as you would with the bigger injectors. The power comes on hard when wiretap kicks in but it’s much more linear with bigger injectors as in smooth solid power all the way up the rpms. I sorta like knowing I have the wiretap power there when I need it but with that being said I don’t really use it in my daily driving.

Get a quad you can't go wrong with it on the VP truck. 

 

Absolutely...

 

What we started out with on Canned Tunes and now moving towards a fully programmable tuner is way better than years gone by where injectors were the factor if a tuner smoked or not. Now you can have much larger injectors and be smoke-free. That way the RV275 injectors are so popular is that was the best injector to stack with a "Canned Tune" tuner and still get a gain of powrr and be smoke free. Now with the Quadzilla Adrenaline guys are reaching 150 HP and 250 HP injectors and still keeping smoke-free to fairly smoke free. 

 

@Quadzilla Power is it possible to consider in future cable design that allows the Quadzilla module and bluetooth head moved into the cab? Be great for smog states and cities to be able to hide the module under the dash and just have wires under the hood. Being Quadzilla can run headless makes it a perfect tuner for this case.

Yes, we just need to figure out an in cab power supply that is powerful enough for us to drive the ignition circuit (constant power) and a good ground point then in cab installation shouldn't be an issue at all with just some adjusted cable lengths.

Hi Gents.

If I can hop in here with a question along the same topic. I have an HTB2 62/65/13ss with a Pulse Adrenaline and Mach 1.6 injectors. Essentially I want to lower my EGTs because I will be giving the truck to Dad and I want it more user friendly so he doesn't melt anything. If I move down to RV275 injectors (or even 60HP injectors) what will the result be? I called HTT and they suggested moving down in injector before I move down to an HX35.

What are your thoughts?

@Quadzilla Power maybe I can lower the EGTs by a lower injection pulse?

Thanks!
