For some reason I'm having trouble linking my videos. Hope this one works.

 

That one worked, I hope your fuel guage is bad if not you need fuel before doing that stuff.

 

I've watched the wideband a few times with low fuel levels. Haven't noticed any leaning anywhere. It would show on the wise band correct? Normally don't try to do that. You hear the dinger going off when I start the video.

 

nice!! as said above though.......watch that fuel man. dont want to rail it and have the low amount of fuel roll backwards away from your pump and lean the cylinders!!

is the turbo your running one of the gt45's?? i have a new one i bought cheap from a guy a while back but havnt tried it out yet. wondering what your opinion is on it if so??

 

I've got a near identical setup in my 86 camaro.

Stock 4.8 ( stock cam, stock gaskets, stock everything)
Ls1 intake manifold for hood clearance
69mm ebay gt45 turbo
80 lb dekas
11.5 afr and 13 deg timing
3" ebay intercooler and 93 octane pumpgas

Ran 123 mph on 12.5 lbs of boost, weighed in at 3615 lbs. Math says 520 rwhp.

 

Not bad, yes def make sure you have more gas then that. I did that the other night with just a bit over 1/4 and thought I toasted something. Scared the **** out of me when it popped and bang. Thankfully it was ok.

 

Not bad for a little eBay turbo truck is running good
