LAUNCHED AT 6500 THE CAR SPIN IT S *** OFF AND WHEN IT HOOKED IT TOOK OFF,,,,TIRES WHERE AT 20 PSI
THEN ON THE SECOND LAUNCH, I LAUNCHED AT ABOUT 7500 WITH TIRES AT 10 PSI THE CAR FELL ON IT FACE AND THEN GOT BACK UP WHEN I SLAMMED SECOND I HEARD POW I SAID ****ING **** MAN MY MOTOR, BUT SADLY THE PASSANGER SIDE AXLE BROKE SADLY,

60FT 2.403
BROKE AXLE
TIRES WERE AT 10 PSI
LAUNCHED AT 7500 AND BOGGED.

 

What was Mph first run? You started out really high on the psi with slicks. More track time and you will be rolling. Are you preloading axles?

 

yea i was preloadinig the axlex n still not much benefit

 

Im no expert, but....

We need more info. What EMS do you have?? are you using launch control/anti-lag?? What chassis/weight?? It sounds like you didn't have enough power off the line if you are bogging when launching at 7.5k.

What engine mounts? you may need stiffer.

Start with the slicks around 10 psi, launch at a high rpm and work your way down till you aren't spinnning and you aren't bogging. Use launch control to try and build a bit of boost (you should be able to make at least 3-5 psi) or even better, anti-lag if you have it.

You should be cutting 1.8s at least, and what were your traps??

 

8.3's really really really really slow... that's bolt on all motor area

what was your MPH?

 

ok well here is the thing the car is an eg coupe not sure of weight yet,
i figured out a few things so ill check and see what my mistakes are,

i was taking off the line at 7200 but i figure due to not having the 2 step set up is why it fell on its face, so im going to figure it out,

 

I found ou thw 2 step wasnt working so im going to run the car again this weekend at a lower tire pressure n with the 2step working, oD

 

SOMEONE HELP

 

I trap 98mph at the 1/8 with 400whp on a bad pass.

 

o i see, well maybe its traction issues and bad sixty foots what trans u running

 

i ran 8.3@88 mph all motor, on 185/65/14's..............was an RLZ built 2.1L, but still...i got STOMPED by even the worst driven 400whp in MPH

 

too much tire pressure

 

With 279whp tuned on RLZ's dyno I was in the mid-high 7's on street tires. These runs were over 90mph and with crappy 60' times. Also, I did not have any antilag or anything with that tune. It was all launching off pedaling and preloading. With closer to 400whp I was around 100mph........these days 400whp can get you low 11's and possibly into the 10's with some practice. You should also run around 100mph with 400whp regardless of 60' times or any 2-step in the 1/8th.

 

1st run, too much tire pressure.

2nd run, you let the clutch out too fast so it bogged hard and most likely hurt your axle there then broke on the hard shift. You need to fix the launch control and work on your clutch control/preload technique.

 

car was already preloaded when i staged and i was okay just i guess when i dropped the tire pressure something had to go
