When I spin all the way through first, I see 12.2s and 12.3s instead of 12.0s and 12.1s, and that's all due to high 1.8s and low 1.9s at the 60'. My mph stays at 111-112. Actually, in 3 runs last week, my mph was no lower than 112.4 and no higher than 113.2. 2 of them I spun terribly and got 12.2-12.3. The one where I hooked gave me a 12.09. So, my point is that I only hit 108mph when I either miss 2 shifts on race gas or am just on pump gas (<300whp).

look at my sig for mods and dyno sheet. That was done without methanol and at 22-23psi. I have been wanting to do a 1/4 mile run but it rained last friday and moroso is closed this weekend because of the hurricane. I hope they open next week, I am dying to see what I can pull off with race gas and around 25-30psi.

here's a stupid but germane question:
Are u running that quarter with 18's??? That'll slow you donw and explain the time+mph disconnect. . .otherwise, INVEST IN SOME TIRES MAN!!!

I've never spun in 1st. . of course I've never pushed her. . .

You are seriously confused.
You keep telling everyone here that their dynos #'s don't match their trap speeds. But you think you now make 20-40 more whp and have not dynowed the car yet! Last post you sayed you are around 330-340, how do you know that? A flash won't give you 20 to 30 whp on your particular car. You need to dyno your car and don't guess anymore. You guess alot and that is wrong.
Just to prove you wrong, my car has gone 12.99 at 106. How many whp you think I have? And you will probably answer 270-280 based on your trap speed theory.
That would mean you are making more hp than me, right? Because you trap 12.01 at 113! But I have cams and a few more mods than you have. And my last dyno was 335. How is that possible? More mods, more whp, bad dyno? yet you are 1 full sec quicker than me and near 7-8 mph faster. But I bet that if I give you one car lenght head start from a 45 mph roll, I will drive around you by the time I hit 90 mph! Trap speeds and ET's are like dyno's. A slow shifting driver will put a question mark on your trap/et theory. It does not allways work that way, yet you swear by it. Quit that.. I have pulled on many other Evos that trap much more than me. And I was not even tuned right back then. I was traping 13.2's at 104-105 and driving around Evos doing mid 12's at 110+. I am not a good driver, all we need is supporting mods, and the car will do the rest to be fast. I hope this makes sence to you. It has not yet, but I hope it will.

Talk about spinning and maybe some ****ty shiftings, how about me, 12.2 / 123 mph on 2.0 60' on balb stock tires. Now that's spinning to the line. I'm not on stock turbo, however.

You're the one confused; not me. I _never_ said anything about a flash giving me 20-40whp or whatever you're saying. I SPECIFICALLY SAID that I didn't gain ANY HP from the flash, because I was already tuned. I said I _probably_ gained 20-30wtq (not whp), because with the S-AFC, I was only getting 269wtq due to the mid-range timing loss (timing dips to 0) that is inherent with any S-AFC-tuned car that has stock injectors. The flash gave me a solid 8 degrees of timing from 3500-5000rpm, whereas before I was seeing it drop to 0-1 degrees, then climbing back up slowly. This lack of timing causes a big loss of torque. Likewise, the flash gave me that timing back (and then some), which has the effect of raising peak torque significantly (e.g. 20-30wtq). No, I haven't dyno'd since the flash, but I dyno'd before the flash and got 294/269. I said after the flash that I'm probably at 294/285. What's the big deal there?

The only thing I'm lacking is a dyno on race gas. I'm sorry that I haven't done that for you yet, but the last 2 times I dyno'd, I only got 3 runs, and that's just not a lot of time when you're trying to dial in your pump gas tune. Race gas is also not available at the last place I dyno'd either, so it's not the easiest thing to do. I am assuming that I put down around 330-340whp when I'm on race gas based on the typical 30-40whp gains over pump and the fact that a 113mph trap matches 330-340whp. All the factors point to this as a logical solution.

Now, on to the bad driver theory. Yes, of course, a bad driver can seriously affect ET, but a bad driver will have a tough time affecting MPH negatively. Look at G20. He's having trouble hitting 11s, yet he's trapping 123. Why is he trapping 123? Because he's making a !$#*load of power. Notice how his trap doesn't match his ET? That's due to bad driving or terrible traction. Bad driving and/or terrible traction does not run a 12.7 @ 108, because that's pretty decent driving there. Likewise your 12.99 @ 106. That's not good driving, but that's on par with stock IXs and stock VIIIs. Hell, I ran 13.17 @ 104 stock with a bad 60. That's also right on par with you, but 20-30whp lower. So, yes, I would guess you are around 270-280whp. Talking about how you pull on people on the highway is pretty lame. Anyone worth their salt knows that 1/4-mile trap speed is the TRUE measure of power delivery...not a dyno.

nightwalker

There are too many variables involved here. (Altitude, track prep, tires, rim size, driver, engine state of tune, humidity, gas, vehicle weight, blah, blah, blah, blah, blah) This argument will always go on without an end. (As it always seems to)

....I'm going to put in a gazillion parts and make a gazillion hp, and put half a gazillion down to the ground and run a 10 second quarter mile! I win!

can some guess my power with the mods in my sig???

Our track is very hard to get good times, especially in the summer(it's the desert). They never prep the track for us either, so traction is always a problem. I guarantee if you brought your car and ran it here, you wouldn't be running the times you are at your track. My best trap is 111, but are consistent 107-108 with 12.7-12.8 times. Here is my timeslip and dyno sheet:





So yes, my dyno numbers and times do match.

And yes, I'm running on 18's and will be borrowing my friend's stock rims and tires the next time I run. Also, when I pull 1.7 60ft I still only trap 108. For the record, the fastest time a stock '03 evo has pulled here is a 14.2. I don't remember the trap speed.

Let them come down here to Vegas and run their cars. I havent seeen anyone not run AT LEAST a half second or slower on this track than the track they ran previously.

Warrtalon

iTrader: (6)

Yeah, yeah, I hear this all the time. Look, the same factors that cause you NOT to run well at the track (heat, altitude) are the same factors that affect your HP. See, these factors don't actually affect you at the track; they affect you ALL THE TIME. The reason why you only trap 108mph is because you are making power that gives you 108mph. If you make 330whp or 360whp in that same climate, then you should be able to go run a mph that matches.

Now, take my care for example. You are saying that I would run slower there than I do here. Ok, that's probably true, but again, that's because I'd be making less power there than I do here...not because of the track. You say it's not prepared well, but you cut a 1.81 60'. I cut a 1.92 after spinning all through first, hit 2nd and kicked sideways, yet proceeded to run 12.36 @ 112.6. Notice, I was .2-.3s off my best times, but my mph was still there.

I see the dyno sheet, but that doesn't matter to me. What matters is your trap speed. If you came down here in 60-degree weather at 500' above sea level, you could probably dyno 330/360, but you'd also be able to run 113/116mph. I also am not sure whether you're doing runs on 91 or 100, so I don't know what mode you're in: 330whp or 360whp. If you hit 111mph on 91oct, than that is much closer to matching, but if it's on race gas, then nah. You said even on a 1.7 you hit 108...so how did you hit 111? What changed for that run?
