The Crawford Package

Performance
256.7 hp / 243.0 tq

Discussion
"[P]lenum, cats, strut bar and headers. The price has been set at $2350. $2150 without the strut bar. Headers alone are $1300." - Doug

This set up also used the Borla TD exhaust which is not included in the Crawford Package or its pricing. Add $630 for this modification and we have a grand total of $2,980. And, was there an intake that's also not included in the package or Crawford's pricing? We don't know.

The JWT/LBMS Package

Performance
255.3 hp / 243.2 tq

Discussion
"JWT Popcharger, LBMS testpipes w/resonator, Borla TD exhaust. The cost was $1,220. You don't have to lose handling by removing your strut brace. And you can get more power by adding some headers." - Dan

Conclusion

Okay, let's make this a positive post instead of a negative post.

It's $2,980 vs $1,220 for the same horsepower and torque. For those of you that want to spend less than half the price, and have room to add more hp/tq with headers, go JWT/LBMS! Or, another way to look at it, you can get the same hp and tq of the Crawford Package with the JWT/LBMS package for less than the price of Crawford's headers!

 

ok all I have to say is you cant add like that if you want to put this kinda stuff up you have to show what HP and TQ over stock the cars gained especially because we have seen stock dynos from 220's through high 240's using your logic why wouldnt you just go get a z the dynos 245 stock and add an exhaust

Dang, you're right! Why didn't Crawford and I both do that?

 

not that it matters to me, or a lot of us, but the crawford package is smog legal.

 

I love posts like this "Zero" Info!! first off how can we make this a positive post if you start it off attacking crawford, everyone who read this is now dumber than before. Lets see Dynos, Pics, Video, and see which is actually better. My money is on the Crawford Z spanking your popcharged Z up and down the street! but what do I know!

 

Correction I just learned something " crawford package is smog legal"
thanks 2003z

 

it would be very interesting to see a car dyno with the crawford package, then substitute the lbfm test pipes and see the difference.

 

this is not a good comparison

different day

different dyno

different conditions

different cars

 

Looks like this thread got shot.

 

Yep, all true.

The only way to properly compare is to use a stock car. Use all the parts of one manufacturer and dyno. Then strip back to stock and use the parts of the other manufacturer and dyno.

Nevertheless, it is a comparison for whatever it's worth. And, until someone cares to really do the above, it is what it is.

 

If I was attacking Crawford, I would have said, "for those of you who want to spend twice the money, buy Crawford."

August 2003 is when you signed on. I've never met you. But, if you come to any So. Cal. meet, lets chat about this thread.

 

where were you on our dyno day? i thought u signed up?

 

hfm:

I want to commend you for accepting others input without turning it into a mud slinging contest. All info is good if you interrupt it for what it is and what it is not.

Your comparison was not perfect but most magazine articles I see published do not do accurate testing themselves. We all need to weigh what is valid data and what is open to being questionable.

First off , No excuse for yesterday, I should have made it,

As far as this thread goes, Everyone is gonna believe whatever they want, but too many people just believe what they read and what people tell them, I am by no means and expert on any of this, this is is the first forum I have ever used, and since august 2003, it has become abundantly clear how bad information gets spread around to people , shops ,dealers! (the service rep @ nissan told me I would get 20hp if I changed my oil to mobil 1) , This forum has helped me with every issue I have had with my Z, for that I am thankful, but all those issues or decisions would have been resolved much quicker if we didn't have to weed through bogus info and posts,
The first post in this thread says "Shootout" maybe its just me but that means there is a winner and a loser. I don't see an IMO anywhere in your post, I see your "conclusion" in which you pick a winner and then try to reword the same conclusion in a nicer way.
Who wouldn't want to spend less to get the similar HP & TQ, but without really giving any good info, we are just going to have a bunch of pissed off people that dropped $1220 in hopes to get $2980 in performance (whoever did congrats) . Crawford doesn't need me to defend them but, from a business standpoint I'd be a little angry if it was my company, The only thing positive you typed about Crawford was the HP & TQ #'s everything else was negative i.e. "without the strut bar", "Add $630 ", was there an intake that's also not included in the package or Crawford's pricing? We don't know" , "grand total " . These are what pissed me off.
IMO all you wanted to do by posting this was let everyone know "your" opinion. which is fine, that is why we all are here but, I would have liked to see that in the post to let everyone know thats all it was.
If you would like to talk about this thread more thats fine more than happy to, but maybe I should let someone with the crawford package take over.
Lastly as far as me turning this into this into a mud slinging contest, your 100% right it only turns into a contest if somone throws back, if not someone is just getting mud thrown at them!

 

Just in case anyone missed the three pages bout this same thing. !! some of the posts look really similar????

https://my350z.com/forum/showthread....0&pagenumber=1

 

the day every Z dyno's on the same exact dyno im not comparing dyno numbers...


THat same Z that dynoed stock 240 might dyno the same day at 220 on a different dyno...

 

Im looking to make some mods to my car but im noticing alot of variables too..I hope this isnt a dumb one but..
just an observation from all the posts floating around these dynos.........

shouldnt it be noted that not only were they different cars different days but I dont believe the crawfords have a lightened flywheel in their dyno?Wouldnt that account for a few extra HP's in ones reading? On what numbers were posted wouldnt that also skew the numbers since your not comparing apples to apples in a mod missing or added in one but not the other?

That seems to me like it would account for at least a few additional ponies and also the $$ amount to get those extra ponies if costs matter has to be factored in right?

So really what can be said other than is this turning into a whoever spends whatever wins or loses and it shouldnt because then everything done to your car has to be factored in if its any type of performance mod.

This is good info though someone like me needs to know whats worthwhile given the relative newness of the 350z and perf mods for it real verses not worth much.

 

Thanks Jeff. Nicest thing said on this thread so far and I appreciate it.

That's right, this is just my opinion and you can take the data for what it's worth. I absolutely agree that the comparison isn't very good but it's the best comparison until someone does it right.

Oh, and as for calling the thread a shootout, I only did that because I saw another thread with the same word. It's not a contest by any sense. Just something to read and evaluate as you wish.

This is a very good question that I don't know the answer to. For quite sometime, I've read threads that say a flywheel will gain no hp but may lose some low end torque. It was my initial impression that I did lose some torque after installation. But, then 350z4Steve posts that beatiful comparision of stock vs. lightweight flywheel that showed something like 5-7 hp gain.

I don't know what is correct, I'll ask my technical expert buddy the next time I run into him at a meet.

For posterity, the flywheel can be purchased for $400-410 dollars and should be included in the above comparison since it appears some horsepower maybe had.

Thanks for everyones comments.

 

Cool, I'm glad we are all in agreement. about your flywheel where did you buy it and get it installed?

 

I got it from Coz with Concept Z. Excellent transaction, I'd recommend him for the purchase. He will match or beat competitors. Installed at Torrance Nissan while tranny was dropped for new tranny after gear grinds.
