It seems to use some oil....motor has 1300 miles on it(Speed Pro Plasma-Moly rings???)
Again the cam and timing chain were install by Golen.

 

I agree. Whenever I would get my Mustang dynoed we would lock the converter.

 

Can you do that through cats? and where?

 

Good question. I dont know but Id like to know, or at least know what the % is to compensate.

 

The dyno chart for the GTO looks better.

The dynapack isin't going to show as high of numbers as a dynojet either unless it set in a interia style mode for doing the pulls.

Ok all this is cool but does anyone have any ideas on what the problem is or where to start looking???

 

The only thing I saw was that the A/F could be leaned out a little. I run 13.0:1 tuned by Bryan Herter....There's a few hp to be picked up there. How does it run on the street? Did the tuner say that he saw something wrong? Dynos are a great tuning tool, but its no replacement for the track...Let your mph be your dyno...

...and maybe its me, but those flow numbers seem kinda high for stock size valves, especially the exhaust side...

 

it really is hard to tell anything with out some of those logs posted.

 

I have the datamaster logs........How do I post them.

 

You can tranfer the file to a spread sheet I forgot what format and then save it. Then you or somebody has to host the file and then yo can put it on here. Or you can just email it to those who would like to see it.

But I agree with the above. IF the car feels strong then hit the track and let the trap speed do the talking for you.

 

No, you can't lock the converter with CATS. You need a Tech 2 tool or you need a switch to hotwire the lock up solenoid in the tranny. Do you still have a lock up style converter?

As I said on RCFB, you're likely starting the run after peak torque so it's messing with the numbers a bit. The AFR numbers look good, you could probably lean it out a bit to around 12.8, but it's not a big deal.

.CSV should be the spreadsheet format in Datamaster.

Bring the car to Ruby's tonight and we'll dyno it on 295 South.

 

Sorry cant make it out tonight......... Do you want to take a look at the logs and the last program for the car?

 

Yeah, I can probably look at them later tonight. Send them to the house.

You still planning to show up on the 18th?

 

Sent...pass them to mean lt1 if he wants to take a peak. I may make the 18th not sure right now. Originally I was going to the track that weekend but now?????

 

What valve springs where used?

I also have an issue with stock valve sizes and a stock TB. A 383 should have a 58mm and larger valves wouldn't hurt either. Kind a like asking your girl to break dance while you squeeze her neck so she can't breath.

It also wouldn't hurt to check the clearance between the heads and the pushrods. 1.6's move the rods closer to the heads and in some cases can be rubbing. Since I don't know who did the heads or installed them, just thought I would ask.
