So I posted awhile back showing my results on a Mustang Dyno with the mods installed below...
2009 Z06
BTR Stage 2 cam
AHP untouched heads
Kooks 1 7/8 Headers / X pipe with cats
Borla Exhaust
Fast 102
NW 102
Airaid intake
ATI underdrive pulley
Monster Clutch / Flywheel
New spark plugs / wires were installed as well
Mustang Dyno Results WCF 510 Hp / 489 Tq
Ok now to actually get to the question...
I see Dyno results on here all the time, results usually coming from a DynoJet. Mods similar to mine and folks are posting Dyno charts from a DynoJet showing anywhere from 570-600, the higher end of that spectrum maybe they have a slightly larger cam, but still the numbers are quite impressive.
just for fun I wanted to see what my car would put down on a DynoJet vs. what it already put down on the Mustang Dyno. Results do not make sense to me. The shop I went to did 3 pulls. Temp was about 60 degrees outside, motor was warm but not hot.
HP 513 TQ 487 on a DynoJet. I don’t get it....I was under the impression that a Mustang Dyno typically reads 10-12% lower than an Inertia style Dyno.
Results are posted below from both Dynos. I fully understand that a Dyno is a tuning tool and nothing else, but this is just strange to me. I was expecting to see around 550-570 on a DynoJet with all the mods that are on this car, especially with it reading 510 on a Mustang dyno. The car has been tuned twice now. Runs amazing. Pulls very hard and violently. I guess I just need some advice from the experts on what they are seeing here and if this is normal. Sorry for the long post and thanks for your help / input.
I don't think I've seen too many 570-600 hp cars with your combo. To me, a legitimate 570-600 rwhp car would require ported and milled heads, and a bigger cam than yours (ex. BTR 3).
2" LT's, ported MSD, and a bit more cam than a BTR3 would surpass a real 600 rwhp threshold.
Also, not sure why your dyno operator used "Uncorrected" versus SAE or even STD. Either way, I'd say you're power "should" be mid 500's in the real world.

Reason: spelling
2010 Z06 22k on car when tuned (Feb 2014)
BTR 3
LG Super Pro 1 7/8 headers, x-pipe, no cats
WCCH cnc ported heads, milled .010
Ported stock intake
Vararam cai
Stock clutch (the original one still at 60k)
I did all the mechanical work and had a somewhat local tuner with a Mustang dyno. Made 570 rwhp and 495 torg
He missed the tune. I had way more exhaust fumes in the car and would cause me headaches (which I never get).
Kept saying he would recheck it but never did.
So I took it to 21st Century in Addison 2 months later for a retune (1st tuner missed the timing set up) on a Dyno Jet.
Made 575 rwhp, 500 torg. (STD).
Don't know if that helps but I didn't see any real difference between the two.

I agree 100%, I just think it’s crazy with some of the numbers people are seeing on the Dyno. I just posted in a thread where a member posted he pulled 605 hp with the same mods as me, same compression, but he has a BTR stage 4 and ported heads no milling. 100 more hp from going from a stage 2 to a 4, and ported heads?

That would seem off to me as well...but I could easily see ~50-60 hp for those two items.

That does help thanks for posting that with your results. Great numbers btw, I’m sure its a beast! I guess my car needs more cam to see better results. My tuner who is very respected in my area, tuned the car and said he was blown away with how much air the motor was getting at WOT. He was very impressed with the intake, Fast and NW 102. With that being said the car would probably see better results with a bump in compression, and a bigger cam.
Could be running low on timing...see if you can find a timing map as well as the IAT spark reduction map. Possible knock pulling it down too. Could easily explain 20-30whp loss.
OP, if you’re happy with the car who cares. I bet it sounds badass and runs like a beast. Go destroy those back tires.
if you want to make more power mill the heads and use a bigger cam.
Mine made 557rwhp 504tq on a very well known dyno.
GP tuning stage 1 cam
Mamo ported PRC265cc heads(~11.4:1compression)
Callaway intake
Mamo MSD
Mamo Ported stock TB
Stock manifolds with cat deletes
Tuned by GP tuning on e60ish
My cam is slightly smaller than even the Torquer 116. Just for reference.

Also i Can say in Germany we have Dynojet MAHA dyno and another Dynos... but on the Dynojet we have the Highest WHP and on the MAHA dyno lower results its maybe Like a Mustang dyno..
ALso 600-620hp On the Crank on the MAHA dyno aprox 500-510whp
And on the dynojet aprox 540-550whp its about 620hp on the Crank loss performance is lower but the Crank hp Like same to another dynos.=leftpower loss on the dynojet its most Lower than another dynos but the when we converting to Crank horsepower comes almost the same.
Wheel tire combination and transmission ratio outside temperature air pressure plays everything a big role

Great numbers especially thru Stock manifolds. Yah this is ridiculous. I just watched a Dyno pull on YouTube C6 Z06 same mods that I have, same cam specs, car was tuned by Pat G and it shows the car made 600rwhp and 548tq on a DynoJet haha I really don’t understand at all how the numbers can be that far off. My Z is getting PLENTY of air. No restrictions whatsoever. The heads are brand new from AHP, although not mulled or ported, but still an LS7 head flows damn good from the factory. The car is an absolute beast. It pulls incredibly hard. I’ve had other cam/head cars in the past, and this one by far is the most powerful, but I don’t know what’s going on with the Dyno results. I just had our local tuner who is very well known and is a very knowledgeable when it comes to tuning LS7s, tune the car right. I sat in the car with him for 4 hours, as he adjusted all fuel / spark tables. Car runs better now than it ever has, I just don’t understand why I’m not seeing anywhere near the numbers others are. I’m at the point where I may switch out the cam to the torquer 110, have the heads milled, put it on E85 and see what she will do.....

Theres nothing crazy about it to be honest. As I mentioned in my thread, several members on this forum hit the 600hp mark with a BTR Stage 4 cam. The stage 4 is quite a bit more aggressive than the stage 2. Im sure with some milling I would have gotten up a bit higher than 605hp. You are stressing "100hp" more. It is not "100hp" more, your car should be in the neighbourhood of 540-550 which would reflect an actual difference about 55 to 65hp - not 100hp more. If the dynojet your car was on spit out the same numbers as the mustang dyno you were on, something is up. Take your car to a different dyno jet and if you still see low numbers, re visit your tune. Anyone interested in seeing how I went from 440hp to 605hp the link is below...

Honestly looking at your mods I would be looking at the cats. Been multiple threads that people are not making what they should be with cats. They cut them off and gain a bunch hp and tq. Your cats can be bad, either way some thing is off if you’ve been to two different dynos with similar results.

maybe, but they are brand new high flow cats from Kooks. They were put on the same time as the rest of the mods 6 months ago, so I don’t know...
I honestly wouldnt lose sleep over it. If you got the same results on both a dynojet and a mustang - something is up with that dynojet! We all know Mustang dyno's are heartbreakers lol. Your numbers seem right for a mustang. My 605 definitely wouldnt be 605 on a mustang. Im sure another dynojet will give you higher numbers. btw im gonna add cats - losing 5 - 10hp wont bug me but what does bug me is smelling like I was fixing my lawnmower. Sounds sick though lol
so you’re seeing 30 more hp than what I’m getting while still using a stock throttle body and I’m using a NW102. Your results are what I expected to see. Ported heads are probably not good for 30hp, but hey I could be wrong. Someone already said this, but I’m curious about Timing now. May have to look into that.
Nw102 wont help unless you are maxing out the stock TB. I only see 2kpa difference from 2000 to 7000rpm so a nw will only add 2% more hp at peak if I were to swap from stock (im around the 600whp club)
