Got my car dynoed at Topspeed in GA. Mods are in my sig. boost set at 21psi, 93 octane, mail in flash from "dynoflash"
Topspeed uses a dynojet but Doug told me that his dyno reads lower than other dynojets.


First run: 317hp 313tq
2nd: 315hp 306tq
3rd: 319hp 310tq

What do you all think?




Here is a link to the dyno

ohh can someone tell me why the line on the HP is nice and smooth on its way up but then kind of bounces around up on the top RPM? I dont know what that means...thanks

 

What type of boost gauge do you use ?

 

It looks normal for a dyno jet to me

 

It is a autometer gauge

 

I am getting a ported stock exhaust manifold and a SS o2 housing put on this weekend. I hope this brings me up to 330-335.

 

I would say that you should test your autometer gauage your boost is down nearly 2 psi

 

How's driveability?

 

i'd say its a lower reading dyno..you have similar mods to me and i put down a little more power. its good power though, especially because the tq and hp are so close.

 

I will turn it up some and see how it responds.....can you tell me though how you know this, i am sure that you can tell by looking at my graph,but i am curious. Thanks again Al.

 

I would venture to say he is taking a guess because your power is about 20 whp below average for your mods. I would test your boost gauge to see if it is accurate before you just go turning up the boost. (not the greatest of ideas)

A custom tune on a dyno/street would probably yield you some more power

 

Your tune was done on the street right?

 

thank for the smallest dyno chart that no one can read. but you know what you can still see from it? its a decent tune, you HP comes on very liniar.. looks good

 

It was just a mail in flash...i turned up the boost some and the car feels alot better now...it spikes to 23 and tapers from there. Under a hard load pull in 4th it did spike to 24psi...but the car as a whole feels alot stronger.

 

sorry but while on the dyno jet topic,i just did 346awhp on tt dynojet w/ helix 272 in. and exh, helix gears, mr mani, mr o2, invida dp cd cb, aem intake, 255 and xede at 21psi thats just seems a little to high.
