Gonna strongly advise against that. Even if your diff doesn't blow you're just going to spin 1st-3rd worse than you already are.

If you really want better times/higher trap, get some radials or slicks. Don't launch unless you're up to the task of replacing the diff if it blows though.

More practice would also do you good. Your time got way better with each run, I bet you could get into high 11s with the proper footwork on your current setup.

 

I would think that mid 120s should be doable with a full clean pass but I don't think you would ever get that not launching. Just watch out for wheel hop with those tires.

 

Im looking at my time slips right now and had/have a very similar setup to yours. I made 507hp/374tq on a 30r P-Tuning kit and 255/40/17 Ventus RS-3 near brand new when I went to the track the frist time. I launched the car right off of the 6500 2-step/Launchcontrol on both runs. Both runs I pulled 2.11 60 Foot times, both runs 8.22 660 foot times, first run was 12.55 @ 116 and the secon run was a 12.45 @117. Car also had a very aggressive boost by speed setup evans-tuned so it wasnt seeing full power until 95mph. On my 3rd pass I snapped the axle on the line lol. I knew it was coming... worst part was I owned a truck and trailer but had the great idea to drive to the track 2 hours away so had to wait 4 hours for AAA to show up and tow me 97 miles home(perfect under the 100 mile tow for free radius lol)

I completely agree with you man. From how fast the car is on the street I really had higher expectations. Thought I would atleast be able to power my way to a mid low 11 and 130 trap even with a awful street tire launch. It was definately a huge learning experience for the first time out. Also should mention the car had a major loss of compression on cylinder 2 (140psi vs 220psi+) and I never once even checked tire pressures or anything like that. My shifts were absolutely perfect of the 9200rpm and I believe I was just hitting rev limiter in 4th gear passing the 1320ft.

Get a set of ET Streets or M&H Racemaster Drag Radials and get back out there!

 

Agree my hurt motor with a little less power than he had trapped 117. I was suprised actually that the RS-3 did not hop once on the track when I had it there. More so acted like I was driving on ice and slipped smooth and straight 1st and 2nd until mid 2nd I got pretty good traction, just a little spin in 3rd, and good from there.

 

Ahh. No launching for me then. Haha. I was pulling 2.4-2.5sec 60ft times on all 4 runs 8.8sec- 1/8th @94mph. I was definitely just rolling off the line. My track was also 2 hours away, and I really did want to run more then 4 times, but decided not to push my luck.

Im sure my car is faster than what i trapped. My buddy with a evo 8 dynoed at 400whp 400wtq on the same dyno ran 11.3 @125mph. I didnt expect to beat his e.t. but I was pretty sure my trap speed would be higher. Ehhh. It is what it is. 120 mph is still fast.

 

A 2.5sec on street tires is absolutely horrible...and will definately effect your trap speed too.

I wouldn't worry about it until you get atleast in the 1.90s-2 on street tires.

 

Best thing to do is to do a highway pull with your buddies evo!

 

Timeslip up. Vid to follow.

I sure do want to run him from a roll!!

 

^ this is where us turbo s2k guys own ALL! haha

 

yes! highway is where my car pulls good. haha. video is up.
