Slow 1/4 times.

Big J · 09-29-2011, 11:02 PM

Went to the track tonight and pretty much ran mid 14's all night. Ive been racing for years now and the track was prttey sticky. So I dont think my slow *** times were driver related. I only have test pipes so could that cause a power loss problem? The only thing I could think of besides that is I added some oil earlier today, could adding to much cause a loss in power?

what is your trap speed

Big J · 09-30-2011, 08:22 AM

97

m4a1mustang · 09-30-2011, 08:29 AM

What was the density altitude at the track?

And your 60' times? Would be helpful if you could post all of the details from your best slip.

A 97 mph trap seems like you were either dealing with a high DA, were very slow between gears, or the car just isn't making power for some mechanical reason.

My best stupid user trick for losing power so far: accidentally set the parking brake adjustment on the rear shoes too hard, they were dragging a bit the whole time

It's easy to adjust with the wheel off though, there's a little rubber plug on the brake rotor. Pull that out, rotate the hub until you can see some little teeth through it with a flashlight, and reach in there with a screwdriver and turn the adjustment gear.

2 things...

1 your wheels whats your rear rim tire setup/ like 285/35/19 on a 10.5 inch rim

2. your test pipes took some torque from you too probally

ScGRaceR · 09-30-2011, 09:07 AM

and do you have LSD?

cossie1600 · 09-30-2011, 09:38 AM

with traps like 97, he has more problems than lsd and wheels.......

traction control wasnt on was it?

Big J · 09-30-2011, 10:15 AM

Trac control was not on. Car is stock with test pipes and stock sport tires on sport rims. Ill try and ipload a slip later today.

tranceformer · 09-30-2011, 06:27 PM

Glad to see some summer racers.

Waiting to see the time slip(s). 97 mph?

cossie1600 · 09-30-2011, 06:58 PM

A very fast rx-8

Big J · 09-30-2011, 08:04 PM

Well my wife was kind enough to throw the slips away. All runs were 2.3 60ft at 97-98mph and ranged from 14.45x to a 14.9xx. The 14.45 had a 2.3 60ft and I launched around 1500-1800 rpm and didnt spin at all. This thing just feels sloppy. I was in memphis, tn, mir raceway. I dont know the air density altitude but will look. Im about to check oil level right now.

Big J · 09-30-2011, 08:33 PM

Checked the oil, its definately over the H mark, just past bend in the dipstick to be exact.

ScGRaceR · 09-30-2011, 09:10 PM

okay the oil level is one thing but if you could get your 60' down into a 2.0 that would help

i think your test pipes took some torque from ya too
