Well the s-techs are good for Drag but not RR, I didn't know if the Swifts, that are good for RR, would be too stiff for drag. If they would work good without hurting my 60' then it definitely be the cheapest way to go. If not then it sounds like coilovers would be the best bet to suite both tracks and I'll look into the N1's.

I know I can't expect the best for both worlds and if I'm going to sacrifice one track over the other it would be RR. Swifts or low end coilovers like Megan's would be good enough for me at RR since I'm not competitive in that at all. My RR experience will be just open track days with some friends (for now). Now Drag, I will be getting into more and more competitons.

could you break down my time slip? I was running on a friends enkei rpf01 on nitto nto5 tires 235/40/17. I was shifting to 5th by about the 1000th marker at 7k rpms. I tried running it out to 8k in 4th but it was just shy of the ET light. If I switched to 245/45 should I be able to run out 4th?
forgot to take picture of the feet.

60' 1.87
330
1/8
mph 89.69
1000
1/4

 

Not Most-wanted but maybe I could help you a bit, it seems all you need to do is work on that 60' foot, the 330 mark seems a bit slow so maybe a bit of practice on that 1-2 shift will help your times a lot too, good luck on the 11's you're pretty close.

Ask a lot of the good drag racers and they will tell you that the 1-2 shift is one of the most important parts of a 1/4 mile drag race. Btw it is much much easier to shift the 1-2 when you get a good launch than when you're spinning tires, I learned this the hard way.

 

You need to avoid the 5th gear shift. It will kill your et. Raise the rev limiter to about 8400 and maximize the 1-2-3 gears(shifts 7200-7500 give or take a few hundred). Also practice the 1-2 to get slightly better 60' times. You should be able to manage low-mid 1.6's. Practice makes perfect. Tire pressure needs to be around 20 psi also so make sure you check that. And most importantly check them when they are hot and after the first run. If you set them to 20 psi and then make a run or two they will creep back up. So its best to do it when they are warm and I check mine every run to keep the variables consistent. Good luck...

 

@ most-wanted thanks, I will do all those and get new/better tires 245/45. I will be out there again when season opens.

 

I'm so glad I saw this thread, I love your car man. Blue

 

Most Wanted: Very awesome thread man. Can you give me some insight also? I don't have my timeslips on me, but I'm running a 7.90 @ 89.6 mph with a 1.9xx 60 ft. I know for a fact that my car has the potential to be running better than 7.90's but I cannot stop spinning for the life of me. My tires were only at 28 psi, so I'm assuming that lowering them to 20 next time should help a lot? My 2 step is at 6000 right now. And my power is in my sig. Thanks bro!

 

Definitely lower your tire pressure some. I typically run mine around 20-22psi (with tires warm). You might want to lower your two step some as well. I know every setup is different, but 5500rpms seemed to work best for me when I was around that range. For reference, I went 7.67 @ 89.8 with a 1.64 60ft. I slow 1-2 shift kept me from breaking 11's on that pass.

 

Yeah, I'm thinking my 1-2 shift is also a problem too. I just dunno how the hell to make it faster...it's such a quick gear.

 

No way lowering the 2 step to 5500 is better. It needs to be 6000 at a minimum. You adjust wheelspin on the launch with the right foot... It is critical to keep the rpms up.

 

What size of tires and what brand of tires do you recommend for a 17x7" wheel?

 

Bumping a old thread cus is worth it. Lots of good info in here.

 

I've been buried in the 12s, and have been assuming that I'm a 12 second driver, 12.1s and 12.0s everywhere over the past couple years.

This year I'll be changing that and getting my low 11s, mod list in sig.

What are you trapping? I'm assuming your on the factory clutch. Is it possibly slipping. You definitely have the mods to get you there and some. Also, not sure what the point of running e85 is at only 24psi, you could be doing that on pump.
