good deal

 

you and blu running on stock intake too

 

yeah and when i ran 14.7 with a y pipe.. i also had my biggie smalls cd in the car.. maybe i should pass them out at the track next time

 

this could be good.

 

yes I can't wait to go back with intake, headers, real y pipe, test pipe, and rear section. I hope to better my times

 

I'll give it a try. I'm running out of bolt ons.

 

When I ran my 14.5 with a y-pipe.. I had the 8-Mile sound track in. Maybe you should switch CD's??

 

I have to agree with sprint on this 1. To prove my point the last time I was at the track which was last thursday there was a 2K26spd there with nothin but the Ghetto Airbox mod and a cattman catback, thats it! Hes had a few max's be4 and even built a 350+whp 4th gen be4, Hes been a lurker on these board for a while now. He was runnin mid-low 14's due to horrible wheelspin but was still Consistantly trapping over 100mph and once ran 102.X This I belive is the highest trap of any N/A max with only one bolt on and the Ghetto Airbox. He didnt have slicks or anything else. Just a good driver & a fast ride.

 

You can't base your debate by the fact that you witnessed a guy running good times without an UDP. Not trying to kill the messenger here, but what about those of us that religously dyno and track test our cars.

Here's my experience. I NEVER hit over 95mph until I added the UDP. I also never ran better than higher 14.8s. After the UDP, I was consistently getting 14.7s@96+mph in 50-70 degree weather.

As for the dyno, unfortunately I don't have a true before and after dyno with the UDP, but this is what I have to go on. With an HKS intake, Stillen y-pipe, and Courtesy B-pipe, I made 174fwhp and 193fwtq. A year later, I added an UDP along with replacing my Y-pipe with a WSP non-mandrel y-pipe. I ended up making 183fwhp and 193fwtq, but what was amazing was the increase in power from 4000-6200rpms. At some points I saw as much as 12fwhp/fwtq gained.

NOW, I have a very hard time believing a NON-MANDREL Y-PIPE out flowed a MANDREL BENT Y-pipe that dramatically. Now granted the WSP Y-pipe is slightly larger in diameter, I don't think it is solely responsible for such a significant gain. The dynos were on the same machine and under the same correction factors. The dyno operator didn't seem one bit surprised at the gains when he overlayed the before and after graphs with the UDP. He said he usually saw UDPs gain more mid to high range power on Mustangs and he figured my car would be no different.

Dave im not tryin to say I dont belive in the UDP. I for 1 am gonna get a UDP in my next car with is gonna be a 2K3 6spd in the coming months. Im gonna do a basline dyno after 7000miles just to be sure its 100% broken in. After that ill do a few Be4 and afters with the ghetto air box mod (like urs ) and the frankencar just to prove it works better again. Ill also do a be4 and after of a Udp which im sure isnt gonna gain anymore then 2-3whp but im sure will give more torque then that. I mean comon it weights like 60-70% less then the stock peice. I am a beliver in the UDP and will prove it with a dyno when that time comes. Im just stating that there is a car out there trapping 102 with basically 1 bolt on and a K&N panel filter. If he had slicks im 100% sure that car would yeild the best ET of any N/A max, with the 60ft times he was gettin that night of 2.5-6 thats alot of spin. He can get mid 13's with slicks im sure of it, Im just amazed that all he has is a Ghetto Box and a catback.

 

Please consider that tracks make a huge difference in the way a car performs too. Someone who's running mid 14s@102+mph with horrendous 2.5 60 foots in a 6 speed with intake and exhaust is pretty much an anomaly. Same goes for 96Sleeper in his 14.4@98mph NA auto 4th gen. Some tracks are definately better than others. Prime example, when I had my 94 Z28 with a few mods, the best I could do at my track in Kansas City (1100') was a 13.7@101mph with a 2.1 60' in cold 40 degree weather. I went down to Houston (sea level) for an F-Body event and I ran at HRP. With no other mods or changes, I ended up pulling a 13.4@104mph with a 2.1 60' in WARM 70 DEGREE WEATHER. See what I'm saying? .3 quicker and 3mph faster in warmer weather with the same car and a different track.

When I went to the track last weekend in Kansas City, VQMan was ran a best of a 14.8@95mph in his stock 2k2 6 speed. His 60 foots were deep 2.4s (much like this guy you keep talking about) and I don't see how it's possible for him to run 7mph+ faster and .3-.4 quicker with two mods that might add 8-9fwhp on a good day. Charles in his bonestock G35 auto was ran a best of 14.7@95mph with a 2.3 60'.

Like I've said before, if people start assuming their 2k2 6 speeds are going to be running 13s@102mph wiht basically nothing done or if they assume thier auto 4th gen with all the bolt-ons is going to run 14.4@98mph, we're going to have ton of disappointed people in this Org.

As for the UDP, you'll like it. It will do more for you than you think. The Ghetto/hacked airbox? It's a sweet, simple, and cheap mod that just plain works.



Dave

 

Let's take a trip to Alabama and run at that track.

 

Please do sometime...I think that would be awesome.

 

Wow thats fast.

 

 

Automatics represent once again! Too bad I can't pull anything better than 15.30's here in this high altitude CRAP.

 

Being land-locked altitude is a biatch!!!


Dave

 

you should make a trip to NC or AL...from the looks of aarons traps he is almost 1 mph slower with 1000 more altitute. Looks like you might tip 100 traps with the ecu if you did

 

Yes, being in Vegas sucks Dave. But, the time in my sig is at Fontana, CA. That is 1000' elevation.

BUT... in Vegas, it's 2010' elevation and the track has been proven to incline 12' over the period of the 1/4 mile. I dunno if most tracks do that or how much it will slow me down. But I am exactly 2 tenths slower than my personal estimate.

My best time in vegas is a 15.547, followed by a 15.548, 15.551. My car is very consistant. I am going to win the gold when I go race my car in this bracket race event this weekend after next at the Vegas drag strip.

My best trap speed since I've been here is 15.55 @ 89.45mph. So, I am 1 mph slower in Fontana and 3mph slower in Vegas. I think the Vegas track is higher altitude PLUS just a slower track.

Anyway... very good time Dave.

Oh yeah... Matt, if I really need a fast track, there's a track in Sacramento, CA that is sea level... but it's a 9 hour drive from Vegas. That is my only option. I believe I am doing about 14.70's in the 1/4 right now sicne I have done a few more stuff to my car.

 

Isn't is amazing just what 1000' will do to the performance of a car? A 12' grade over a 1/4 mile isn't horrible, but it sure won't help things. How about the 1/4 mile track in Japan? The damn thing looks like it's on a 10% DOWNHILL grade!!!!! Jeez, talk about an advantage. Some tracks are perfectly graded while others seem to go up or down hill. I know the track they use for Autoweek is really downhill (somewhere in the Northeast I believe).

It seems like for every 1000' you gain about .2 and loose 1 mph. Sacramento is a quick track, but is it worth it to run at a track 9 hours away? I couldn't justify it. Neal's talked about me coming up to Illinois to race, but that would be a 7-8 hour drive for me. Sorry, but a 2 hour drive about all I'll do unless it's some huge Maxima meet is going on or something. I've just learned to accept the fact that I'll be slower and I'll never post terribly impressive numbers. I do constantly dream about racing on a nice sea leve track though

Goodluck.


Dave

 

the autoweek track was the site of the last maxus,75 80 dragway it goes uphill. I didnt know elevation was such a power robber my track is at 1500ft. This summer im going to english town at least once what do you think the difference would be?

 

 

That's weird because on TV, it's very clear that they're racing the car downhill. The slope is very apparant. My wife completely caught me off guard and said, "whoa, that track really slopes downhill." Unless Autoweek is racing the wrong way down 75/80, I'm pretty sure I can recognize uphill from downhill j/k


Dave

 

75/80 is in my backyard (almost literally...15 minutes away) it is definately UPHILL. i have never heard of autoweek testing there, maybe i am just oblivious. i would hope that they wouldnt associate with that track, it is the worst one i have ever been to.

--Paul

 

What track did you set this record on?

 

Yes thats were nthey test,its a terrible track i took my foot of the brake at the start line and rolled backwards.

 

 

I haven't set any records


Dave

 

I'm sorry, what track did you run this time at? And I also thought you are the fastest NA 4th gen auto?


*edit* I'm sorry, I meant what track did 96sleeper run this time? Sorry Dave.

 

When I was droping off money and picking up tickets for that particular Maxus, I saw Autoweek there and they were runing in the opposite direction; but I don't think it was the 1/4 mile run, I think it was the brake test.

 

Steele, AL

 

Thank you. I saw his time in the 1/4 mile forum after I posted. Alabama Speedway has an awesome track at sea level.

 

Oh, I thought it was 500ft above?

It is a good track though, I love their prep!

 

You're right. Steele, AL is roughly 500 feet elevation. If you were at Fayetteville, NC, you would be atleast one tenth faster.

 

I WAS AT THE TRACK WITH HIM THIS DAY. He ran right before I got there so I didnt get a chance to see 14.4s but he did hit 14.6 versus me. I think that the conditions were better earlier in the day when he ran cause i dont think he hit 14.4 again after I got there. I totally believe that his car did it tho...the thing is a beast...pulled on me the entire race(when I had y pipe, intake, and ACT running pretty consistent 14.7s). Makes me think that if I had gotten to the track alittle earlier my best would be around 14.4-14.50 right now before my newer mods.

Double post>you.

 

Wow!

 

Im curious to try 15" radials with lower profile tires too see what I would run

 

I'm too lazy to read the whole thread to see if it was previously mentioned, but what altitude is this track at?
