best pass was
60' 1.938
330' 5.737
1/8 8.893
mph 77.67
1000 1.602
1/4 13.875
mph 99.11

That's not bad.

The MP62 looks to be tapped out since you didn't gain that much trap speed despite nearly doubling the pressure.

Good '60 too.

its got belt slip like shit aftger about 6200 rpm the runs i short shifter were the fastest, im gonna have to figure out a 6 rib setup cuz the 4 rib shit isnt cutting it

i was only 0.325 sec slow; not too shabby.

ahh the joys of supercharging

If he did not have belt slip I bet Pdexta would have nailed the ET and trap speed almost exactly.

but he didnt take into account how shitty SC setups are!

lol

Better carry a couple spare belts and a can of the "anti-slip" spray with you at all times.

I can't hate too much though. I kinda enjoyed the last MP62 setup I drove.

i got two spare belts :) that anti slip spray is a goddamned joke tho

Time for a cogged belt.

fixed

The moss kit uses a 4 rib still which is useless on a m62. The setup I made uses a 6 rib and at 14 psi with a barely tight belt no slip ever.

Dang, too late to the party but reading through this thread I was totally thinking 13.9ish

So my guess was going to be 13.9 BUT by "The Price is Right" rules I still lose...or did I win. Going over in price is the same as going under in 1/4 mile time estimate? I mean I WIN

then you would have won. but you didnt guess!

Considering you lose if you go faster than your index time in bracket racing, I would think if you choose too a fast time, you lose.

If that was the case, I would actually be the winner. If you go by Speed Channel's Pass Time rules, pdexta is the winner. At least I was closest on the MPH.

That is the thing about guessing times. The art is factoring in what is most likely to happen including conditions, and what is likely to go wrong.

Funny thing about tracks of any kind, problems have a way of floating to the top.

say no to belt slip.

Fixed that for you:

Just think, if you really work hard to optimize your car and struggle to drop .5 seconds you will be only as fast as Troy's naturally aspirated car above.

if I zeroed out the alignment and changed to skinny wheels and blah blah blah it would be quicker in the quarter. its an autocross car man. I was just taking it out for shits and grins

laguna that is what I was planning on doing with the overlay pulley. I figured to cut a ring of .25 aluminum then weld it to the s/c pulley and have it machined for two more ribs also.
