Well This week the Tc76MPS is going on.

At our DA of almost 7000 feet it ran 14.97 at 91.xx MPH... (stock tires)

Now with the turbo and 6 #s of boost to begin (probly 8 shortly after... lol). What Kind of improvment will be seen with a decent tune and 6#s of boost?

Most people at sea level area claim a 1 - 1.5 sec improvment. Seeing my altitude is just out of control here, and boost help make up for it over a N/A motor, I was hoping to see at least that if not a bit more. (1.5 improvment would make me happy).

What do you guys think? No matter what happens a forged SBC is goign in as soon as i can

 

you should be able to run 8-10 pounds if your that far up in the air man..lol it may put you to whata NA car runs stock down here!

lol.. come on! lol... i figure 8 lbs would get me somewhere in the area of what a car closer to sea level runs with 6 lbs... 10 lbs would probly put me right (lil better at least) at what someone runs with 6 lbs at sea level....

just a big guess really... altitude makes things hard to estimate...

 

Your figuring about right when you say 1 to 1.5 seconds. Problem is once you add that boost to it, if your running stock tires, you may blow the tires off it and then you'll be lucky if you get a second just cause your 60ft's will be bad. If i remember, when i put my s-trim on my old setup and ran boost only at 6psi, i think i cut off about 1 to 1.2 seconds. I'm at 5800ft and the DA's sometimes get to 8000 up here. It's a killer.

You'll probably pickup 10mph or so...
