Well all ready for the dyno. went out and got my tune all dialed in thanks to Kbracing96 About 15-16 PSI is all this turbo will do, it is maxed out up at this altitude. Waste gate has 14lb spring, and hoses are off. Fuel pump is about done also. Injectors are at 85%, and going up to 98% Dosen't change the AFR at all. Im at 11.2AFR. I will post as soon as I get off the dyno. I don't know if the numbers are corrected to sea level or not? If so, numbers should be fairly strong. I think it is making around 500 hp up hear at this elevation.

 

[quote=stock48;3848225]I know the altitude is going to hurt big. Don't know how much RW HP it takes but the truck is trapping around 120MPH up hear @ stock weight. What does that take?[/quote]

hmmm, a bunch. LOL well unless you going down mountain. Good luck with the dyno today.

On the PSI thing, did you install the boost controller to the top port and make adjustments.?

Lets me know when your ready for the larger piping.

later

 

Corrected or not, that thing has got to be making a TON of power to trap like that with full weight at your elevation. The strip is the real dyno anyway, but it sure will be interesting to see. Very nice combo. Good luck!

 

Make sure you put a 7-9lb spring in there with some sort of controller.If the weather changes and the elevation goes down you will probly push alot more boost and run out of fuel.

 

most dynos have a corection for that. I'm intested in the numbers with that cam....

 

My numbers were altitude corrected. I bet yours will be too, Im guessing mid to upper 500's altitude corrected. Can't wait for the track to open up, well have to make a trip up there together and beat up on some F-bodies, lol.

 

I'm going to guess it'll make about 480 at that elevation. You picked the right turbo. I'm not sure why you can't dyno it with the converter locked. If a 4L80E can't be dyno'd with the converter locked in, you have a problem. Locking the converter at wide open can be hard on the converter, but with your own tuning software you can set the shift points yourself for the dyno run so that the converter is locked before you even go wide open which will take the stress off of it as well as be able to run the rpm as low as you'd like. I've done that many times. If it really traps at 120+, what does it run in the quarter?

 

My guess - 583 hp and 644 tq.

 

I'll bet he's over 600/600 corrected. I'll guess the ASE correction factor at 1.20-1.24 also, lol.

 

i say 589.5 hp
