Dyno'd the car tonite.

[twotonefreak]

Well made a couple pulls on they dyno, not real thrilled about the numbers, but so far of all the cars they have dyno'd seem to be about 30rwhp/lb.ft off from very similar combos. Oh well I had to drive for about 35 mins and the car was only able too cool down while they strapped it down. Final numbers were 239.11 rwhp and 272.94 lb/ft.

Hmmm......you're right, I would have been expecting at least 260 out of that. What was your A/F ratio? Can you post a picture of the graph?

What size injectors do you have?

 

[twotonefreak]

Here is the graph.

 

[twotonefreak]

I still have the stock T-body, MAF, and injectors. So far he has dyno'd one 2.80 pullied 03 cobra, and a stock 92 GT, and a stock 00 trans am. The 03 did 420/440, the 92 pulled down 180/270, and the trans am did 280/310. Most of the 03s that live about 3 hrs from here (but they only have a 2.93 pulley) here are in the 460-70 rwhp and 470-80 lb/ft. I would have expected the LS1 to pull right about 300rwhp also. Who knows, I think I may have to drive the 3hrs and make a pull on that dyno, I know its a Dyno jet like the one here, but I think they are different models?

On my first run, I don't have a graph of it, but the lines were super shaky, and just didn't pull as hard. Time for some more fine tuning and a couple more upgrades along with a custom tune to she what she will do.

Here is the graph.

I see no graph.

Forget this one.

Let see if this is better

How about a pic of the full graph.

**** I give up. That link isn't working.

 

[Venom351R]

Yeah seems like there is some type of tunning issue there, w/ my mods you only pulled 8 more RWHP and I pulled 13 more FT LBS of TQ

 

[WhiteDevil]

Yikes, that is way low man. Look at mine in the sig. What was ur A/F ratio like??? What about timing??

 

[twotonefreak]

The dyno owner doesn't have his A/F equipment up yet. He just got everything up and going yesterday. I knew those numbers were low, especially when my friends 03 Cobra w/ a BBK CAI, 2.80 pulley and o/r H only pulled 420/440 when many, many others are churning out 460-470 w/ same tq. with a 2.93 pulley?? I don't know. Also my car isn't tuned at all. I just have the timing at 14 and fuel press. at idle is 33lbs.

 

[twotonefreak]

White devil, what is your timing and fuel press. set at?

 

[WhiteDevil]

I have it at 14 degrees, and 42psi no vacuum, thats with #19 injectors though(dont know what u have) . Not sure what it is at idle with the vacuum on. My air fuel was 13.7:1 almost all the way through my dyno run. I also have the fuel pump which helps it from dropping off.

 

[twotonefreak]

My fuel pressure is 33 with no vaccum, I still have the stock 19# inj. also. I don't know, maybe dyno operator error? Oh well I am going to try and set something up at another dyno about 3 hrs. from here and see how big a difference, if any there is. They are two different models of Dynojets.

 

[94VIRGINIASTANG]

You definently need to turn your fuel pressure up.Id set it at least 42 with the vacuum on at idle and go from there.

 

[WhiteDevil]

Yeah im surprised your not pingin really bad up top with on 33psi no vacuum. Turn that up a little man.

 

[rudeone707]

Those numbers are kind of low, i would say try taking it to another dyno shop, that way you can see if it is just his equipment, if its a new dyno shop he might not have everything hooked up right.
