Those numbers are nice to look at ... ... but not realistic with the mods to the car. 400-405 rwhp would be alot more realistic numbers for that combo.

 

I understand that the numbers are probably too high, but I can tell you it's not an ego think. I can care less. The car's paid for and after the cam install and tune it really runs great. So many are just content to buy a car like a Z06 and do nothing to it. I can't do that, I love to work on motors and I really enjoyed working on the LS6. The last motor I built was a 383 in a 72 Z28 and I had $11,000 in it so I know how some of you guys feel when you spend big bucks. Anyway the tuner did a good job and I'm happy the shop is only about 5 miles from my house. I guess the numbers are about like going to the track and getting your picture with Dale Jr., it doesn't mean your his best friend just because you got a picture.

 

A time slip will tell the real story...dynos are tuning tools...make a couple of passes and you will know the truth.

 

The dyno is configured with a 2.1 parasitics mult. and a 1916.71 equivalent weight.... vehicle weight was at 3200lbs and 15.6 hp at 50.... this will get you close to dynojet numbers...(for argument sake)....and runs were made in 4th gear...
The car when brought to me was misfiring from being so rich....that's why it only made 330whp on its first pull....the gains were true and the car was running a nice 12.8:1 AFR with 25* timing on 93oct....I did NOT fudge any numbers to impress and would never dream of it...ENJOY!!

 

Thanks Jack for the info, you did a great job on my Z. The tune is great and I'm glad you chimed in on the thread. I love it when someone is proud of their work, and I'm sure proud of your work that for sure.

 

Thank you for the support Paul....I appreciate it very much!...I stand behind my work 110%....it's guys like you that keep me coming back for more!

That statement alone says the numbers were fudged.

 

yeah because u said it was on a mustang dyno but its was configured to read what a dynojet would measure. so yeah your number is good....bc it was on a "dynojet"

 

My experience with trying to make a Mustang Dyno read like a Dynojet is you can not make it accurate at all Hp levels. If you fudge the calibration to make it read close to a Dynojet at say a 300 Hp level it will be way off on a higher Hp car. It is best to just leave it calibrated like Mustang says to calibrate it.

 

If I get banned, so be it. His job was to tune my car. That he done very well. I could give a s**t about the HP. It was just a number to show the gains in the tune. Where in the F**k do you get off? Do you own a dyno? What makes you a better expert than someone who does own a dyno? Do you pay your families bills with the money you earn dyno'd cars? Are you even a mechanic? I was really thrilled with this forum and I was really happy about my car's performance at the tune. You guys need to get a life!

 

getting the AFR correct is whats important ,you know it will run hard .just don't get a big speeding ticket.take it to the track on a club day and enjoy.

 

I am glad you are happy Paul....that is what matters to me. And I am sorry if anyone feels I have misrepresented his dyno numbers in anyway...they arent important to me...only the gains. as long as the gains are there I can rest assured knowing I have done my job correctly. The dyno is a tuning tool... its not a race track.

 

Corvettes will dyno higher than F bodies any day of the week. Congrats Z06 brother! Sounds strong!

 

4z, One thing is for sure. It is very strong. Texas Speed DOES make some kind of HP. (And it's very driveable)

 

Gains are Gains & Loses are Loses, when tuning this is all that matters.

Changing the Parasitics Multiplier will "not" effect how the Dyno loads, it only changes how the numbers are displayed in the end. There are calibration measurements made by accelerating the rollers to certain speed, place the car in neutral or clutch in & letting the rollers coast down, this is done several times. Parasitic curve is the fancy name, if I remember correctly. The Multiplier is used to caculate from that curve what final numbers are displayed, no effect to loading.

Thanks BoostCry for clarifying your Dyno Parameters!

 

As long as you enjoy it and it does what you want then who cares what it dynos.

 

You are incorrect sir if you are referring to a stock LS1 powered C5 and a stock LS1 4th gen F body. The independent rear suspension on the C5 uses more HP to get the power to the rear wheels than the more efficient straight axle in the F body car. I have seen it happen dozens of times when the stock F body put down 10 -12 more RWHP than the stock C5 Corvette. Those engines made the same HP in the real world but GM rated the C5 engine higher on paper to feed the egos of all the Corvette owners.

 

Those darn GM guys OP enjoy the new found horsepower, at the end of the day the only number that matters is the number of pissed off ford owners. Thats the number you should be swingin for

 

Welcome to the wonderful world of ls1tech lol! btw nice zo6, I would be happy with it!! Don't pay any of the nay sayers any attention, they feed off of it. your numbers look about on par for that setup. Most cam only 02-04
zo6's dyno anywhere from 420-450whp, depending on dyno, cam size, and supporting mods...

 

Thanks, I enjoyed installing the cam in the LS6. I've done many an install on the old style motor but this was the first in a LS. It was fun, everyone needs to do it, it's really worth it in the end. When I pull away from a stop light with my Borla Stinger exhaust it really sound great. And I want to say thanks to everyone on this forum who helped with info.
