here are my best two of the night

r\t .182

330 5.766
1/8 8.545
mph 90.37
1000 10.889

mph 114.14

r\t .093

1/8 8.604
mph 89.67
1000 10.956
1/4 12.947

sct seems to work really good i need to put my clutch in, up the boost, and invest in slicks or DR

nice r/t, nice 60', nice et's, especially for a slacker.

love to see what that does at 20-22 psi.

[theslacker]

thanks, when i get some DR ill up the boost in 1st and 2nd from 14psi to 16-18psi and see what she does then install my clutch and run 20-22psi

[ReDsRtKiD]

That's a pretty nice trap for only 18.5psi. You just need to invest in a clutch and crank that boost up and it will really wake up.

[addictedtosin]

Thats not too bad. Your driving is very good to run 12s on street radials at 18.5. Nice runs

[theslacker]

thanks, i've raced at the track many times but fwd is a diff story with a little more practice i should cut my times down more. I'm looking for mid 12's on 18.5psi

[lVlemphizStylez]

Very nice...I concur with what you're doing...Mastering 18.5 with mid 12's before cranking up the boost. I want to say I bet that tune you have is probably conservative too, should look at cleaning it up a little, could pick up another 2mph on your trap probably

[Pablo]

Very nice, was this on the .63 or the .48ar?

[theslacker]

.63ar

[Pablo]

I don't see a returnline, do you have one/ If so what's the base pressure.

[lVlemphizStylez]

with the SCT tune he doesn't really need one does he? The software should be able to control the injectors to it's liking up to the max duty cycle. Or am I not understanding this SCT flash?

It can be used with or without, not sure if there would be limitations without the returnline using sct or not, I already had one when I went sct so I didnt look into that.

[theslacker]

yes i have a return line at 50psi, but with sct u dont really need one, but its recommended

[srt4does13s]

i dont see how you are running those times. on my 57 trim i spin till 4th gear on the same boost levelof 18 psi

Maybe you should invest in a set of tires then. I've had 4 different aftermarket turbos in the past few years and have made over 400whp and still only spun in 4th gear once to my knowledge. Try some of these, I still blow them off in second on pump gas and 20 psi, but they should help you even more than they help me.
