Well as I said in my last post a few days ago i have the nitrous working finally and the local track, Moroso, opened for the first time last night since the hurricane. With the 125 shot my first run was 11.96 @113. Ended up getting 3 runs in and improved to 11.92 on the last one. 60 ft's were all in the 1.6's with the best being 1.61. I was very pleased with the results since I really dont have a ton of power adding mods done besides the nitrous-cai, sct tune, o/r x pipe and 4.10's. One thing I did forget to do that I had planned was to remove the front swaybar but its ok bc there is still about another month here before they close the track for a fe weeks. I will post the dyno chart and time slip on here whenever I get my internet back up at my house. Thanks, Jan

 

Good #s man!!!!

 

Good times! Got a quick question though since I am weighing nitrous/cams vs. a supercharger. Why are your traps so low? I trapped 108.4 and 109.1 in my N/A car with the mods listed below. You have 125 more hp at the crank and I would think you should be trapping somewhere around 116-117. Does the Zex kit incorporate an rpm window switch that sprays from certain preset rpm point. If so, what is it set at?

 

Well done, Jan!! Congrats!!

Time to update your sig!

 

Congrats! Welcome to the 11 sec club... i can do 11's...in the 1/8

 

 

Congrats man.Welcome to the club.your numbers are right on with what you have.

Gee...........Another 05 into the 11,s with N20.And how many supercharged 05,s here are in the 11,s???????Its funny how the poll says superchrged all the way but none are posting anygood times.

 

The poll wasn't about which was faster in 1/4 mile

 

He's running 4.10's.. Your running 3.55's.. Let me know if I need to break it down further for you..

When you run 4.10's, you dont make 117MPH traps, unless you want oil all over the track..

I guess he could still safely trap 117MPH with 4.10's.. This would put him close to 6000RPM.. This sounds like it would be more a tunning situation, which would dictate how much HP he has after the 1st 1/8th to finish up the race with.. His trap speed looks like he's playing it safe engine wise.. Around the 5765rpm mark.. However, I think a better tune would help him trap closer to 116 or 117..

 

Your traps usually go up with a gear change, given traction. Oil all over the track? Are you serious? I hope that was a joke or I would have to break it down for you Jan said he dynoed the car, so he most likely has an A/F readout. I would guess that his tune is pretty good A/F wise, otherwise the car wouldn't be at the track.

 

I explained the oil on the track situation already, so that issue is invalid for you to make an arguement against.. It was basically withdrawn based on the rpm area of the engine while at 117mph with 4.10.. It could be done, so my bad..

So whats your theory on the low trap speed? He tapped the brakes towards the end? You seem to know more than your original question implied.. So why ask him the question, if your knowledgable enough to provide the answer?

Are you saying he left the car in 3rd gear? If so, his engine RPM would be around 7610RPM.. This cant be your position? So did he tap the brakes or lift or shift to 5th? LOL!

I gotchya max2000jp!! Your saying he lost traction somewhere after the 1st 1/8th marker!


So again this begs the question as to why ask him the question, if your theory of a loss of traction is the only possible explanation why he could run a 113MPH trap speed.. Or could it possibly be the Zex cut off briefly at a certain RPM? Or possibly his foot bounced off the throttle losing his WOT with the ZEX TPS?

 

I don't know, hence that's why I asked Jan those questions originally. I wasn't throwing out theories such as loss tracion after the 1/8 or leaving it in 3rd gear. Don't know where that came from. Let Jan explain, instead of trying to make assumption. Everything you posted above is asinine and your feable attempt of being a smart hiney wasn't needed.

 

Well, my friend, I think it is more than likley Jan momentarily lossed traction after the first 8th Marker.. Again, we are talking in terms of a 125Shot in relation to a 4.6L V8, in the last 1/8th.. So I think it is more plausable that if in fact his suspension is not setup properly, along with tires and such, then a momentary loss of traction after the 1st 8th marker is more plausable than the Zex cutting out at a certain RPM range.. Not trying to start trouble with you, but just trying to understand all the possible reasons for a 4.6L with a 125Shot did not run closer to 117MPH like you pointed out.. So all though you may feel the debate is meaningless until Jan speaks for himself, its ok to discuss the many reasons why this happened, in conjunction with the more plausable theories.. Everyone will gain something from the debate, so please dont take it personal.. Like I said, I think it is safer to assume that somewhere after the 1st 8th a loss of traction occured based on the 125shot possibly overpowering the the tires and or suspension setup breifly, leaving Jan in a position of making up the speed he lost as a result..

 

Re-read his first post. Jan stated he pulled a 1.6 60'. Based on that 60', we can safely say he wasn't running 20's on KDWs. That means Jan was most likely on ET streets or D/R's. Given that, I doubt that he lost traction after the 1/8. Once he chimes in and posts the slips/dyno and his story we will know more of what happened during his runs. It could have been 90 degrees and humid out there in FL. His ET is there, I am just wondering why his trap was lower than the other 5 speed modded guys with N20.

 

LOL!! See there we go max2000jp!! Nice reply.. The 60' time would indicate good traction.. I'm just diggin man.. Tyring to understand.. You did ask a very good question, and is why I have latched onto this thread, for a minute or two..

Now, what we need to know is his launch speed out of the hole.. Bare with me.. Imagine for a moment that his launch speed RPM in regards to TQ produced by the engine is lower than that of the shift from 3rd to 4th in the 1/8th marker location..

So what I mean is, lets say he launched at 2500RPM.. But after the 1st 8th marker, or somewhere slightly before it, he makes a shift from 3rd to 4th, placing his engine rpm speed around 4500RPM with WOT in conjunction with a 125shot.. Can you see how his 60' time couldnt actually tell us his traction situation around the 1st 8th marker?

 

I highly doubt that he lost traction going into 4th. I also remembered that Zex measures their jets at the crank, whereas NX rates their Jets at the wheels. A 125 shot of Zex is 106.25 rwhp assuming a 15% drivetrain loss. We need to see a slip and let Jan explain, otherwise we are going to continune talking in circles.

 

Both you guys are missing the obvious...

After the first 1/8 mile, the track goes uphill!!!

 

Based on your numbers, which appear to make sense max2000jp, let me show you what happens as a shift from 3rd to 4th happens in a 2005 Mustang GT while on the juice with a 125Shot..

This is the number, the car starts out with, with a 125SHOT of Zex when shifting from 3rd to 4th gear..

3rd to 4th gear shift, and TQ applied instantly @ WOT with 125Shot..

520Ft Lbs. @ 4500RPM WOT 125Shot Zex system..

Now this number tapers off as the rpm rise, but this is what is applied after making the 3rd to 4th shift.. This is how much TQ, all things combined must be able to handle instantaneously after the shift, to finish out the run.. I submit to you my good man max2000jp, a 2005 Mustang GT must stick to the track after this shift, in order to run a 117MPH trap speed..

Also, this is for all GT's.. A GT with 3.55's wont have too much problem sticking.. Add 4.10's and all bets are off.. Better bring your "A" game to the 1/8th mile 3rd to 4th shift when on the juice with a 125Shot of nitrous!..

 

congrats on being part of the 11 second club,buy the way i have 4.30's and went 11.52-112 fuel pump giving up on the high end and trust me there is plenty of fuel in my tune.
