Xzillaraider dyno results!!!

[JCleary]

Well, I couldn't wait 'til the next Dyno day, so I traveled to BRG Racing Dyno Services today in Concord, CA. Very nice people there. They had a dyno day last month that I attended, and I decided to return. They have a Mustang dyno.



My truck ran a baseline today within . 5hp and 1. 5 tq of the run a month ago. Here are the numbers:



Stock-

247. 2hp @ 2750rpm

473. 1tq @ 2500rpm



Level 1, (30hp and 90tq advertised)-

275. 1 @ 2750

535. 3 @ 2500

Gain of 27. 9 and 62. 2



Level 2, (60hp and 120tq advertised)-

298. 6 @ 2750

586. 8 @ 2500

Gain of 51. 4 and 113. 7



Level 3, (100hp and 200tq advertised)-

326. 2 @ 2750

685. 4 @ 2250

Gain of 79 and 212. 3



I know all trucks are going to respond differently to performance enhancing boxes. I would say that Quadzilla is meeting their claims. I'm sure somewhere in the graphs there's a gain above what they claim. What I am reporting here (obviously) is Peak-to-Peak gains.



Pretty impressive if you ask me. A Banks six gun w/speedloader advertises only a 82hp gain peak to peak. (I think DLeno posted that)



Quad delivered the same or better performance for half the price, with awesome driveability to go along with it. The graphs show a nice curve, with a strong bottom end. I'd post them, but I don't have a scanner.



I thought y'all would like to know.

Great post and great results.

 

[JCleary]

I forgot to mention the highest EGT was 1200+/- at the end of the 100hp pull. Boost maxed out at 32-33.

I assume by "stock" you mean intake and exhaust? For some reason that seems like a low number with intake and exhaust. My truck, with duals, ran on a dyno in stock form on Imler's Mustang dyno and got 259 hp and can't remember tq. I would expect with duals and no intake/exhaust I'd be consiterably lower than you. Maybe I got lucky and got one that runs above average? Can't wait to dyno the 140hp box on the dually, but numbers will be a little low due to 35" tires

 

[qzilla]

Those are respectable numbers, but it really does make me wonder about the Mustang dynos. We use them a lot for tuning, but it seems that they are all over the place from dyno to dyno.



It seems the Dynojets are much more consistant. If you ever get a chance roll it on a dynojet. I bet it is right on the advertised numbers.



The mustangs are good dynos, but there seems to be a missing link on most of them. It seems that they are either really high on tq. Or they are low in HP?



Any ideas?



Regardless, good numbers and I am glad you are happy.

By stock I meant with the box turned off. Still had the intake and exhaust on. I thought the numbers on my truck were ok, even without the box. And I am running 35" Toyos. I guess the big shoes will affect the hp rating, but not torque? There must be a huge increase in unsprung weight, reducing the hp number? I'm not sure.



Quad- I'll run on a dynojet as soon as I can. I'll dig up this thread and post when I do.



Are you implying that your box makes the advertised gains peak-to-peak?

 

[CLAYTON]

JCleary,



Do you have a camera phone... thats the easiest way to put pics on here. IMO Take a picture with your phone. . email it to your self and then attach it

Yeah... do something. I want to see that torque rise.

JCleary - how are you hitting that much boost? On 100hp with my stock 305 I can only hit about 23-24lbs. Is it the cool blue hose? Doug Leno had told me that I shouldn't bother because anything over the stock amount of boost just starts blowing hot air and you don't see a reduction. However, I can hit 1300-1325 peak on the 100hp setting. It might be that I can lay into it a lot longer with my auto then with your manual where you have to let off and lose boost. .

 

[qzilla]

Yes, advertised gains are peak to peak. I don't believe in best gain or any other form of advertised gains.



What gear were you in on the mustang? That could cause some funny power numbers. Maybe the 35's just hurt the power? I wish I could get consistant Mustang numbers though.



I know we mad advertised peak gains on Scheids Mustang?

I was running in 5th, starting the run at about 1300-1400 (35mph) to the rev limiter.



Numbers are numbers. I liked the performance already, just had to satisfy my curiosity.



I'm glad you're straight forward with your claims. Everyone should be.

I've read what Doug posted also, but I interpreted it a little differently. Anything much over stock boost levels quits giving additional power. My set of the pants experience with my EZ tells me that additional boost does help EGT's. Without the boost elbow, I easily hit 1350+, and getting @25lbs boost. When I put hte boost elbow on, EGT's were tempered down to around 1150-1200, and boost @34#.



I wonder if there is some diff. between 03 and 04 that allow the 03's more boost. JCleary and I have almost identical intake/exhaust systems. I'm seeing 28-30 lbs right now with the XZ and no boost elbow. EGT's haven't been an issue yet.....

 

[JCleary]

AK RAM- My camera phone sucks. I tried but it didn't work. I'm still working on it, but if you want pm me and I can fax them to you.



LightmanE300- I'm not sure why I'm getting that much boost. I don't have an aftermarket boost elbow. Whatever the truck came with is still there. I can hit 28-29 psi with the 60 setting, and 25-26 or so with the 30 setting.



As far as EGT's are concerned, I've held the pedal to the mat in sixth, and the temps never go over 1250 or so until I back out of it. When I'm running through the gears, I think the temps do come down a bit when I shift. Having an auto probably does cause higher temps due to the fact you are never letting off the throttle.



Another thing about boost-



Stock my truck will spike at 24 and stay solid at 22 up to redline. Are your trucks the same?



With the Xz on the higher settings, the boost will keep rising with rpm all the way to redline.

 

[DLeno]

What I like about the Dynojet is that you can use uncorrected numbers and get very consistent results. there is no calibration needed because the calibration is the drum itself. so thats very cool.



on the boost -- my point is that going over 24 psi on the stock 305HP turbo is putting the turbo out of its efficiency map. that means you're blowing hotter, not more, air. at 28 lbs boost I found that the temperature consequences are severe. See TDR issue 48.



that is not to say that higher boost pressure will yield no EGT benefit. it means little benefit and you are stressing the 'charger.



also note that elevation and truck-to-truck variations account for some variabililty of results.



I know less about the mustangs. the important thing about any measurement tool is that the more you understand it the more meaningful your measurement is. a properly dialed-in mustang is very reliable, but I think there may be more opportunity for variability from 'stang to 'stang.



I made one round of dynojet measurements last fall for issue 47. then another round just last month for issue 48. the stock truck measured within 2 HP over that time difference. very consistent. -- Doug

I've been running an EZ since spring of '03. I never did tamper with the factory elbow, but I have pinched off the wastegate completely. I can hit 40# on level 6, but it does run hotter than level 4 and factory wastegate settings @ 30#. I think the factory wastegate setting is pretty much "spot on", "dead nuts" or whatever you wanna call it for the envelope it was designed to work in.

yep, sounds just like mine. I finally put the Xz back on this morning after having power steering issues at the dealer. Not sure if is taken care of yet, but I'm leaving Friday for a 2K trip, so I'll have a god feel for this thing when I get back.
