Some strong numbers.
Ours made 396rwhp with a small cam and bolt ons.

That is rather strong...

Has it been to the track?

Rather generous dyno..

Something's not right. Usually bolt on Zs are around 380-390. Possible it has a cam?

Sorry I haven't posted, but no, the car doesn't have a cam, I have the dyno vid which I can upload.. But I'm still on the Eagle F1's so I'll have to either borrow a set of radials or buy a set to make a track run. I've beaten a couple h/c/i f-bodies without much trouble, all making around 450+whp.

Here's the sheet, the tuners name is what is blacked out. The video I took of the dyno was actually pretty horrible, it's narrow and doesn't show the entire results screen. I can post a video of the car idling I guess to show that it doesn't have a cam. I dunno.

Theres just no way, the highest bolt ons Z s are right at 400, and they have better intake and exhaust setups than you do

Yeah, something is wrong with the dyno then if you are sure you dont have a cam. You are probably right around 400, the reason you beat the Fbodies is you are around 500lbs lighter

First thing first.

Was the run done on a Dyno Jet Dyno?

I don't think so.

The OP's dyno sheet doesn't look like any thing I've ever seen produce by Dynojet's Win7 software package. Anytime I dyno a vehicle on a Dynojet, I always ask for a copy of of all the Run files so I can study them by viewing them at home using Dynojet latest Software.

To validate my observation since none of my vehicles have been dyno'ed in a few years, I went to Dynojet's website and downloaded their latest version of WinPep software to my home computer just to see if they had changed it in such a way as to produce a Graph sheet like the OP's.

DynoJet Software want produce a sheet like OP's on either the run viewing software I downloaded or the run/view software used by Shops.

I tend to look things over, an both the OP and others here might want to take note of the correction factor for the run, 1.06, no mention of SAE, STD and with the 1.06 correction factor. It must have been one hell of a bad day to dyno, or one hell of a day for the Operator who I believe used a ctrl X on another brand of Dyno to produce that correction factor by overriding the Dyno's weather station atmospheric observed conditions/readings.

Below is link to Dynojet's web site that will allow you to download their WinPep7 software for viewing your dyno runs. It has every feature shop's software has and you can view run data in many different ways.

http://www.dynojet.com/downloads/software.aspx

Just scroll down the page and click on "Trying to View Your run" and you can download WinPep7 viewing and displaying software.

PS: If the Dyno's operator want give you a copy of your run files, find another dyno. You may even have to tell him about being able to view your run files at home...:D

That is outstanding info, thank you for posting this.

Lol, Sorry to say man but you were just on a generous dyno... I bet if my Z06 was on that dyno I would put numbers pretty close to that... On a dyno that is has been actually calibrated correctly your more in the 385whp range SAE....

Here is a typical post for a C5z...just for reference

Sorry Bro, NFW a bolt-on LS6 is making that much power. Get it to another dyno for some real results. Preferably a Dynojet with an operator who knows his machine. That dynosheet you posted is NOT from any Dynojet that any of us here has ever seen. Not trying to be a hater or anything, but someone is blowing smoke up your ass!

Jimbo

woah that is some high numbers for a bolt-on z.

heh funny. Finally found another dyno that gives higher readings than a dynojet (known to be high).

That sheet is from a dynocom dyno. Known to produce very high numbers.

Sounds a bit high even to me with those bolt-ons. My ls6 has every bolt-on in a fbody and didn't get there. But at 426whp and 405 wtq (dynojet #'s) it did pretty well. Take it to the track op and see if it can back up those numbers.

My Z28 in my sig was done on a Dynocom Dyno... I can attest to them reading "QUITE" high.. The numbers were 431/408... :(

Bwhahahahahahahahahahahahahahaha^^^^^

Not possible...with boltons....no way.

Lol i can see a 50 shot getting you there especially the torque.

Yea, even with a cheatR camshaft, the torque on that isnt really logical. Power adders are usually what give you those numbers as far as TQ matched with HP. Sounds like someone at the dyno wanted to make you feel like the 400+ you spent on a tune was worth it lol.

the tune is probly fine, just the dyno reads high

Dyno wouldnt read the TQ equally with the HP like that. If it was reading inflated, it would still have a legit spaceout between the HP/TQ.

I can set you up with a dyno that the car would make 450 on.Talk about cheap horsepower,PM me for info.

Like I said. Take it to the track and see if you can back up the dyno.

Exactly..this happens more than you think. Especially if the guy doing work on your car is also the tuner, of course he would inflate some numbers to make you happy with his work.
