Warrathalon and other dragsters. I'm going to the track soon in about 2 weeks and am contemplating launching the Evo 8 at 5K with shifting between the 7200-7500 RPMS.

Last time at the track I got 14.33, 14.20 and 14.19. This was with 5K launch and shifting right below 7K rpms. Also, tire pressure was all messed up, after the track I checked tire pressure and the driver's side pressure was 30PSI, the rest were 24-25 PSI.

So this time around, the weather is gonna be much cooler. The tire PSI is set at 33 front and 30 rear. Will shifting beyond 7K RPMs help me get into the 13's??? Warrathalon mentioned that shifting after 7RPM will get the RPMS up higher in the next gear.

I'll be lining up against a EVO RS, and 2 STI's.

 

imo the air pressure is too high. deflate them down to about 28 psi to eliminate wheel hop. Everytime I run my car at the track, I take it to 7900 rpm (reflashed ecu), right before fuel cut and then shift.

 

fuel cut at 8k stock?

 

mine's not stock. but if i remember right, fuel cut was at 7200 rpm on my stock ecu.

 

if ur stock there is no reason to rev beyond 7200 in fact that might be a little too high, right at redline is most likely optimum for stock setup

 

^^ excactly !! No use waitng for redline if there is no power in that gear.

I'd short shift 3rd 6500-6800 rpm's and ride 4th gear out.
7200 1st
7000 2nd
This is of course if your stock.

 

Your best bet is to shift 1-2 at 7k and the rest around 7400 so when the RPM drops you will be in the sweet spot for the next gear. Otherwise you have to wait for the power to come on after shifting which will be slower than if you had revved out the gear. Stock rev limiter is 7600 rpm.

 

Thanks! I'll have to try that..

 

although I'm no drag racer, I was told to shift around 7500 if you are reflashed. that will keep the rpm's up when you drop the gears.
I have ran a best of 13.2 dropping the cluch at 5500 and shifting around 7500.
ask whiteevo311, I have seen him run and he is in the 11's on an 05 with very few mods. he is a great drag racer...

 

I disagree with most of these guys, but the one I do agree with is the one who has great times listed in his sig (gkania), although my suggestion is just slightly different. Anyway...

Things NOT TO DO:
1) Do NOT short-shift 3rd. That's just plain dumb.
2) Do NOT lower your tire pressure to avoid wheel hop.
3) Do not shift anywhere near 7600, 7800, or 7900. Also, don't shift before 7000.

Things TO DO:
1) After you launch, choose the rpm that's easiest for you to shift to 2nd. This happens so fast that you can't really "choose" an rpm. You have to do it at the point it feels right in order to engage 2nd quickly and smoothly without missing a beat.
2) Shift at ~7200-7300 in 2nd and 3rd, since you still make good power there and since that will put you in the sweet spot in the next gear.
3) Keep it where it is, and then adjust it according to whether you spin or not. If you spin, lower it. If you get wheel hop or continually bog despite launching at higher rpms, then raise the pressure.

 

I'd have to disagree Wartalon.

When I was stock with my 03. I was running .10 - .20 sec quicker in the 1/4 short shifting 3rd.
I found out there was no power in 3rd after 6500. Tach was still rising but very slow. No reason for me to stay there where I can shift to 4th and be at the fat part of the powerband where I could actually feel a stronger pull.

Just my experience with a stock 03. Which he has but didn't say if he was stock or not.

 

My times are listed below. What were yours? You definitely still make power beyond 6500. In fact, my peak power is at 6600-6800 (both stock and now), so shifting at 6500 just makes no sense.

 

Was running 13.8's. Short shift 3rd on a couple of runs got me better times.

03 power peaks at 6500 rpm's. All my shift's are the same. Better times came late run's but temps were almost the same.

That was in 03. I run mid 12's now and shift past redline @ 109-110.

 

That gives no support to you telling him to short shift. There's no reason to do that whatsoever, for it would just put you below the powerband in 4th. Why it may or may not have worked for you isn't important. We're referring to all Evo's in general, and shifting at 6500 is 100% wrong.

 

I'm not forcing him to do it. I'm just merely suggesting for him to try it.
