So i had a loaner blower on my car while mine was been rebuilt sounded real good at idle and driving. So I got my original blower in and swaped out the units and went with a bigger MAF sct 3000 and ended up switching up my tires from nittos 315/35-17 to MT Et street drag radials 295/45-17 (new).

I did 6 runs.
My best was 13.0 @ 104 with a 2.0 60ft.
all my others runs where traping 105-106.
2.1, 2.2 60ft's
13.2, 13.33, 13.7, 13.5
Wtf!!!!!
I was expecting to be lower in my 1/4 times around in the low 12's with just the new tires while with my 315's i was finishing in overdrive and getting 2.0 and 2.1 60's aswell. My best times so far was a 12.7 on the nittos.

My car did feel slow aswell 3rd gear felt weak.
Overall my car felt slow.

And just throwing this out their is their a break in period for rebulit blower? The rebuilt blower does not sound as loud as the loaner blower I had a P1sc.

How may the 4.10's b to much?

Looking at that you said I bet they just didnt prep the track well. I was there for a FFW one time n that track was bad ***.

4.10s are not your problem tho. With those tires and a good launch you should be seeing at least 1.8s..

Hmmm...Yea the 60ft needs some work...just get to the track more.
