HAHHAHAH, believe everything you read. I went on a scale next to a 04 Zo6 on the same scale same day and he weight just short of 3000 and mind weight just over 3300. we both had about a half tank of gas.

 

Every car is a bit different, that's for sure. What I'm saying is that we have pretty good conditions here to race, compared to some of the tracks out west which are supposed to be a lot tougher.

Way back when I ran high 12s, though, I still had to shift to 4th before I crossed the 660' line. An Evo is running the high side of 86mph when its spinning 7300rpm in third, so if you can trap higher than 86 in the 1/8th (I trapped 86.8 a long time ago as a Stage 0), because I shifted at redline at that time. Even if you boil the car and rev it out to 7700rpm, you're just then trapping 91mph. But the dragstrip doesn't tell your true trap speed at the line, it shows an average of the last several feet.

What that means is that the entire back half of the quarter mile happens in fourth gear, and all the shifting has already been done. The only differences that can effect here are weather/wind/track elevation, etc, and of course area under the curve.

I'm not saying that Jeff's cutout did nothing, but I don't think it will procure 20whp by itself on an Evo. I think his drag racing has obviously improved recently (although he has an 11 second car that he really needs to launch better top get there), and turning up the boost is what made the power.

PS: About your car and Smog's, did you guys ever switch sides or run off the same side? Did you always run on the same day? Do you shift at the exact same RPM point? Are you running the same clutch? Were your dyno graphs identical everywhere including your area under the curve? Because all these things can vary stuff tremendously.

Case in point: Dylan's car has 300whp and ran 91.xmph in the 1/8th.

 

Not ET but MPH. And yes at one time he was a lil slower shifter but if that is the case why the higher trap. I do not care what anybody says; if I shift slow my traps are affected immensely. Coming off boost affects trapspeeds period. FWIW One time I held my 3rd gear a lil longer than usual and trapped 90mph in the 8th however I did not run a significantly higher trap on the back side. Maybe 111mph if I remember correctly. Go out and run 116 mph and than make claims but until then saying what u will do based off of an 1/8 mile trapspeed and Et is really not relevant.

The 3-4 shift will cost U 2/10 s if u can't execute it efficiently IMO.

BTW Great 60ft on that run and I believe that u will run a good et but 116mph trap is pretty good on his setup.

Also about Dyno #s correct me if I am wrong but at one time wasn't Andrew's Dyno reading lower than it does now? So 245 whp and 109 traps are a lil stretch IMO.

 

His car was tuned on C-16 and mine was on 100 oct. Burn rates of the gas maybe helped me down low and yes at one time I was the superior shifter. I did 12.2 s at 110 mph with 1.8 60 fts. Tom did his 12.2s at 112 mph with 1.7 60 fts from what I remember. Stage 1+ days were great!

 

I have a few hundred FWD passes in my life, probably 40 passes on my WRX, and three ever on the Evo. I broke a tranny in my WRX, and it made me gunshy. I respect people that go out there and try, because it is a yardstick of a car's performance, but a ton of variables can mess things up or inflate them.

My point is that you need to realize that you've improved your skill doing it with all those passes. If you keep it up, you'll run an 11 easily. IMO, your better technique and the extra boost are doing a lot more than the cut out. See where I'm coming from?

 

What i was saying, IF you are a better shifter, then you will gain ET, and MPH through the 1/8. BUT since the back half of the track requires only 1 shift as opposed to 2 on the front half smog may have been able to make up all that lost speed, and ET since he only had to shift one time.

 

Dylan's car was 3300 with him inside it! Local Z06es weigh 31xx with no driver. I need to put my junker on a scale and see where it fits in the sceme of things.

 

I know raising the boost had plenty to do with my traps going up, don't get me wrong. BUT, with the cutout open boost is built back faster in between shifts and you can launch with more boost built.

On these fast trap speeds, my "skill" wasn't heing honed as well as previous trips to the strip. i pulled consistantly slower 60' times when i was getting these high traps and my 1-2 shift was sluggish at best(thats all the car would allow, thinking about the weapon R dampner).

Im not claiming 20whp because of anything i did at the strip, im claiming it based on what ive seen with DSMs, grand nationals, ect...

i guess we are just going to have to watch it together on andrews dyno!

 

LOL, tell Tom to call me. Here's the facts here out east:


-John's car made 248whp after Andrew changed the dyno and trapped 109. He never dynoed it before the change.

-My car went from 246whp to 253whp after the change with no other tuning. It trapped 107.x with a horrible 1.8 60'.

-Cooter's car stayed exactly at 245whp both before and after and trapped in the high 108s.


Its just what they actually do with that power out here. Our weather conditions and tracks are different than yours. I think the dynos are reading almost identical now, but only Shiv could answer that one.

 

LOL Noize Sorry I have a big mouth but I agree the tracks out East are a lil quicker but I did not know that about the South. Don't chew Tom out for my cat out of the bag premise.

 

i just don't see how i can trap 109.5 with 290whp and you guys are doing close to that with 45 less whp, thats outragious. my traps were with a 1.70 60' time.

what track you guys running at, and what kind of weather/temp?

i mean, from what you are saying, you should be able to trap about 113 or 114 with my car on 93 octane at 290whp. Not possible at all. No way for someone to make up 4-5mph from what i have it.

we are all talking about evos right?

 

my 109 was in the late summer of last year.

 

why don't you come to jackson, SC on april 23 and drive my car before i dump the race gas in. or better yet, you can drive it with the race gas and see if you improve on my trap by 3-4mph.

going to be plenty other evos there and a lot of fun either way, but i would love to see it happen, because it won't

 

because i dont want to drive to south carolina to prove a point.

 

its not far, like 20 mins from augusta and its a big track day event held by augusta customs. wouldn't only get to prove a point, but race your own car in the 1/4 mile and see what it will do.

if your scared, say your scared
