Okay, before I get too mad, I subscribe to this magazine, pay good money for it and really love their format. I have noticed that they delete data from their articles...many times 60-ft times and things like mentioning last year that the 2001 Z06 put out 335 HP, but dodn't publish Tq numbers or better yet, the entire graph so we could come up our own conclusions about the power curves.

However, that is not why I am a tad miffed right now. Last issue, they tested a SLP MAF on a 2001 WS6 TA and promised to test an SLP Y-pipe. I have the new issue and CAN NOT FIND THE ARTICLE . Okay, could I be missing it...anyone else have the mag? I am considering purchasing this item for my Z, but want to see Dyno results for it. Could it be that the pipe adds NO HP and they don't want to **** off SLP because SLP advertises in GMHTP, or am I really missing the article in here somewhere? If the former is true, this will be the last issue I read, as the magazine has lost all credibility to me. Anyone see the article???????? thanx in advance

 

Last year's z06 put out 335hp? Is it just me, or is that a good 75 low?

 

That is to the wheels....or 335/.15 = 395HP at the motor

 

You've already got your copy? I haven't yet. I've been looking forward to their article about the y-pipe also. If it's not in there I am going to be mad. I'm already mad about them putting a special edition out and not sending them to subscribers. I think they included it with popular hotroding magazine or something. What a crock. By the time I found out about the special edition it was too late and I couldn't find it anywhere. It's the only magazine I subscribe to and I doubt I renew it.

 

GMHTP is like any mag, and will print what they think will sell, and are definately guilty of creative journalism.

The one that stands out the most in my mind was the Nitto 555RII vs. Kuhmo V700 Victoracer article. They had the Nitto's to be 2 seconds faster on a road course, yet most racers (myself included) have found the Nitto's to be 1-2 seconds slower. I did notice that there was a large Nitto ad in the middle of the magazine that month.

Thank god (or al gore) for the Internet, as we no longer have to rely on magazines for tech info.

 

The SLP Y-Pipe is proven to be a waste of time

 

Yeah I am getting tired of their crap too. That scam about the bonus issue in Popular Hot Rodding really pissed me off! It was better than the edition we got that month. I subscribed to GMHTP and don't get my mag in the mail until a couple of weeks after it is on the stands. They always talk about testing this and that, but you never hear anything again. The mag use to be a lot better years ago but each issue seems to be worse than the last. They need to get their s**t together or they will be out of bizznass.

 

I'm angry about this....To the Top

 

I do not agree that the Y-pipe is a waste of time. If you look under your car, the left side were the pipe comes out of the Manifold is all crunched to fit nicely.. I have definatily noticed a difference with the y-pipe.
I also read the article about the MAF and I went out and purchased it along with a smooth bellows. the combinations works well together.
The only problem I had was that the SLP Y-pipe was not long enough. Maybe it was because I replaced the mufflers with the american thunder two chamber Flowermaster,( the exhaust pipe was shorter ) In any case all's I did was purchase a 2 3/4 Band clamp. Replaced the other clamp and it works fine.
If you have a 2001 or 2002 camaro you will definatily noticed the differance

 

Thanx, but I'm a numbers guy....I like to see track time or dyno improvements. Especially with SLPs reputation for, shall we say...being over zelous with horse power numbers. Besides, from a math point of view, volume is volume, reguardless of shape, but admitidaly, I don't know enough about fluid flow dynamics to guess the shape vs. flow charictoristics of the Y pipe. Wasn't the Y pipe one of the same problems Ford had with its underrated cobra...they rated pre producton before the post production cars crushed the pipe?

 

At least you get your issues! I have called, written and I still get no magazine......hell I thought they were gone, out of business!!

As for the SLP y-pipe unless you are connecting it to LT headers you aren't going to notice much!

 

I was waiting for that article as well. I always have to wait for my copy also. Dawm, I hope they read this thread!!

 

We did install and test the SLP y-pipe on this particular WS6, and it produced no change in horsepower up or down. We took it off shortly thereafter. Does that mean it doesn't work? It's impossible to tell by testing on just one car, however, others have reported good results with the y-pipe. We felt that out of deference to our advertiser and our readers that printing such inconclusive results would be counterproductive.

As far as the tire test goes, the Nittos were in fact a quicker tire. The ad was placed after Nitto was informed of the results (which often happens when good results are to be reported). I supposed we would be accused of the same thing if the Kumho tires won and a full-page Kumho ad was printed. I feel vindicated in our Kumho results, especially since Grassroots Motorsports recently backed up what we said about the tire's handling characteristics.

The Popular Hotrodding issue was never announced ahead of time, so I hardly feel its fair to be indignant about not getting it. Subscribers got exactly what they were promised--six issues per year. Popular Hotrodding is sold in nearly every large magazine retail outfit in the country, in fact it's sold in many, many more places than GMHTP. If you couldn't find it, you didn't look very hard (their circulation is over 130,000, GMHTP is about 17,000 newsstand).

On to the dyno numbers. I don't really know what you're talking about on the Z06 thing, but if it relates to the test we did at Strope Speed Shop (2001 Z06), that would refer to horsepower at the wheels, not at the motor. We do not intentionally delete data, but sometimes we must make tough decisions about what runs and what doesn't (needless to say, we can't print data which isn't provided to us by respondents). Right now, I'm taking heat about putting TOO MUCH stuff in the book--putting too many photos in, running them too small in order to fit, running the copy in too small a space. Our editorial package is very small and it forces some difficult decisions.

I apologize for any omissions in the magazine, it is not intentional. We depend on support from our readers and advertisers to keep GMHTP going. If that goes away, then so will GMHTP. I hope you understand.

I sincerely appreciate all the support the magazine has gotten from all the folks on CZ28.com. We'll work on fine-tuning the "Data File" info, in the meantime, I urge you not to take this too personally.

Finally, the decision to limit the distribution of the Popular Hot Rodding issue and the January 2003 calendar is made by those higher up. There's not a day during the PHR production cycle that I don't think about this and cringe. It's really painful, but it's a job and I must do what I'm told. Knowing that I'm doing all this extra work and it's only going to make my GMHTP readers mad instead of happy is not ideal. Ironically, I'm the one who convinced them to do a seventh issue (in PHR) two years ago. I just wanted to provide more content any way I could, but I didn't anticipate this type of problem.

This is the best job in the world, but there are some parts of it I could do without.

 

Johnny, I am not flaming you or GMHTP. I have been a reader since long before "GM" was added to the name, since before I became a member of this board.

I emailed Nitto about 2 years ago and suggested they offer a stiff sidewall version of the DR. I am not saying it was my idea, but I had high expectations for these tires. I was one of the first people to get a set, and while they are an impressive tire, I run faster on the Kuhmo's. Maybe it is my driving style. I currently use the RII's for street tires and V700's for autox/open track events. I haven't seen the GRM article, yet...

Anyway, I didn't mean to sound critical, and keep up the good work

Chuck

P.S. Now what do I have to do to get in GMHTP

 

You may have had high expectations from the Nitto tire, but I did not, at least not on a road course (VIR north course). I've used the Kumho tires on the track for a while so I know their characteristics. No one was more surprised than I to find the Nittos faster in timed laps. You just couldn't cook them too hard because they would "go away" in a very progressive and predictable way. The Kumho will grip like gangbusters then just quit and get "oily" in the middle of a turn. I do a lot of track events so I appreciate the Nitto's predictable behavior. I dunno, maybe it's just a thing I have for good lap times and straight sheetmetal...
