Well just go back from the Dyno and it was pretty interesting. First the conditions. 90.59 Degs. 28.59 in-Hg 41% Humidity. All the pulls were made with pump gas 91 oc. Calif. blend. Worst gas in the world. The first pull was sad.
Pull #1----308hp 311tq. A/F ratio pig rich With 8 deg total time.
Pull #4----332hp 334tq A/F ratio 11.5/1 With 8 deg time.
Pull #5----371hp 366tq A/F ratio 11.5/1 With 12 deg time.

And thats is where we stopped. We could of taken alittle more fuel out to get it around 12.5/1 but better safe than sorry, since temps where 10-20deg cooler then usual. The wierd thing is, is that I am seeing 10psi boost with a 3.33 pulley should be around 7-8psi. I cant wait to get the alkey on, so I can turn the timing up to around 15-17 total. 4degs. made a 30rwhp difference!!! Over all I am pretty happy.

Nice #s. Any 1/4 mile times?

F8L Z71

Very cool!

I'd like to see what it can do with full timing. Get that Alky on there!

nice numbers, amazing how much of a difference timing makes....Allen added 1deg timing and leaned it up a bit and got 20hp

Thanks guy I am pretty happy with it. No 1/4 mile times yet soon. Hey F8L Z71 how do you like your alky kit? I've checked out the web site and they look pretty nice. Are you able to run the PAC on your vech?

F8L Z71

It is the only hting allowing me to run that much boost otherwise I'd be screwed without an intercooler.

The kit is great but it's not a simple plug and play system since it was designed for the GNs but it does work excellent. I feel an IC with Alky is the perfect combo for a street car. You can get your IATs down below ambient which is unheard of with forced induction. This will allow you to run full timing and decent boost on 91 octane.

I do have the PAC hooked up. Made tuning a snap.

What??!! You made how much??!! Thats awesome!! Since you are running the same blower and setup as I am minus the aftercooler, I guess that shows the efficacy of their cooler!!! Man Im kind of pissed!! I just spent $1500 on a new laptop for tuning so Im hoping to get this thing running as soon as I have a free day to meet up with Julio so we can fit a system to the truck. Congratulations!!!

So what was your final a/f ratio on top ?
Can you post the Graph
Did you dyno on the 22's?
Curious too see the graph and how the curve looks compared to an ati
I made 366rwhp and 362rwtq on a stock setup no tuning

The A/F ratio @ 3500rpm's was 11.8 and slowly dipped to 11.5. I was the third vech. on the dyno ever, They just opened a new shop no internet yet. I took a picture of the sheet you can get the just of it. Give me your email address and i will send it to how ever want to see it. I removed the 22's and put them on the wifes Yukon. Looks Sweet!!! So I dyno on the factory wheels.

Greentahoe- I thought you would like those #'s. Get the alky all set up on yours and you will be at the same # probly better even with out the intercooler.
