Everyone has a different idea what they want from their car from being a monster at the track, from a roll on the high way, autocross or just a fun all around street car. I think what a lot of owners seem to forget is that when you typically mod a car to be strong in one area you are giving something up in another. But as long as the owner is happy with it is what matters.

Myself, I'd like an all around strong performing street car that is fun as hell to drive. Strong power, good handling for my country backroad driving that I do love so much and some occasional drag racing/pull with friends. I know that focusing on the handling more I will have to sacrifice some of the launching ability of my car and I'm okay with that. My days of spending every weekend at the track chasing magical ET numbers are over for me. While it will never be the fastest track car here, it will certainly be very fun to drive. :)

Exactly. I've had my days at the track 10 years ago when I lived there every weekend. I could careless now. Sure i'll go every now and then but I'm not going to try to break records and shit. Hence why I haven't bought another set of wheels and slicks. My car is a fast fun street car and that's what I wanted.

So the thread has now come full circle. We saw this on the dyno charts. So what was all the back and forth banter for lol?

That's a damn gd post. I don't live my life a qtr at a time. I'm not chasing a magic time slip.

With you on the bottle maybe. I am not a street racer but a couple of months ago I offered to meet you and line up at Ennis. I showed, ran 10's, and you never bothered to introduce yourself and take that offer up. The way I see it is you spent a lot of money on an 11 sec. car. History isn't on your side when making claims.

There's no point of arguing with you about your car and my car on the streets. One you know everything and anything about these coyotes (ok) and two you don't street race. Prime example my car is faster then what it appears at the track, I race a person in this group and we ran the same time and mph at the track. But we did a 30 roll starting in 2nd gear in mexico and I walked him like he was standing still. It wasn't even a close race. But I expected that since I make 100 rwhp then he does. So if we did ever race on the streets I don't think your car has a chance against mine. Sorry that's my opinion so take it with a grain of salt.

Maybe to you. Maybe to other people they have already decided it is or isn't worth it just based on this. Assigning a dollar value to horsepower is on an individual and case-by-case scenario. So even when you draw your own conclusion, other people might not feel the same as you.

I will say they do know what they are talking about to a point. Not everyone here drag races. And that's all they are baseing their knowledge off of. To me unless you are trying to get the most hp out if your car the CJ isn't worth the money over the boss manifold and a TB.

I have far too much to loose getting caught street racing or killing someone else doing it. I would expect someone with a new kid to consider the consequences.

Same offer I made before, I'll line up anytime at the track.

Explain to everyone what data you have accumulated street racing that shows the CJ intake isn't worth the extra money?

You can get hurt or worst at the track to. You pick and choose your areas where you want to race on the street.

And I made a remark cause your buddy misread what I wrote and said a shitty comment.

And from what I seen from other cars there really isn't that much gain for an extra 500-1100 dollars. The price varies cause people might buy TB for the boss manifold.

And actually my car isn't a perfect example. Like I posted before I race a person in this group who ran the same time as me. But when we raced on the street I killed him by a lot of car lengths.

Man that wbt guy has a hard on for you for some reason. I like how he keeps comparing his auto stall car that he races every weekend and has set it up for that to you car which was just finished and has only been to the track once. That's a good comparison.

Thanks mom.

Because racing on a track is without consequences or safety hazards. I feel sorry for people that are scared too enjoy life to the point where they have to try to critique others for doing so.

-Alex

Grandpa 09-02-2013 11:10 PM

I see both sides of it. You both have very solid points. I just think you are both doing different things.

I like WBT's technical side of posting, but it's heavily track based, which is cool, but doesn't apply to everyone as far as use goes. I DO agree with WBT it's going to be up to the individual owner if the CJ intake is going to be worth the $1k, or settle for the cheaper Boss.


Side note - Jeff, solid posts and well done on keeping your cool bro! :)

Dan12GT 09-02-2013 11:11 PM

I'd like to see the time slips on both those runs. 1 1/10 of a second isn't what I would call measurable evidence.

He is using the tried and true way of measuring performance by using track data. Datalogging, ET's, MPH, 0-60, shifts, temps, etc.

WBT is correct in saying that dyno results mean very little. How the car performs in it's intended envoirment is really the only proper way to determine accurate results.

Some of us old folk were doing this long before the use of dynos were the norm. I use to tune my blower cars the old fashion way with a timing light, reading plugs, fuel pressure and checking tire prints. We had no idea (nor did we care) what the car made at the tires. It was how the car performed.

Now that dynos are everywhere and technology is common place that most people don't know how to work on their cars anymore without a programmer in their hands that the dyno numbers have become more about bragging rights or measuring how a car "should" run.

It happens all the time a car makes great power on the dyno and doesn't run like it should according to what one thinks it should. Same goes for the other way, some cars dyno like ass but run like a scalded ape on the street.

It all comes down to a solid tune, a proper set up and a driver who knows how to optimize all of it to take advantage of it.

No need for this info.

What you said was wrong and was corrected.



Let's break the price difference down:

CJ intake - $720 from Tousley
GT500TB - $100 from Tousley
Intake tube - I paid $90 for a 2010 GT intake tube from Airaid and modified it to fit my existing Airaid airbox.

Total cost: $910

Boss intake - $473 from Tousley
Intake tube - $167 from Autoplicity
No need to replace the stock 80mm throttle body. No gains there.

Total cost: $640

Difference: $270

If you have a Boss intake already and want to move to the CJ you spent quite a bit of extra money. If you are running the stock intake and haven't decided, an extra $270 over the Boss setup isn't going to break the bank.



Sure it is. Puts up great dyno numbers (500+ WHP) and runs a 119MPH trap speed.

Yet I crushed a car that runs the same mph that makes less power then me. I'm pretty sure I would pick up mph if I was able to launch the car at higher rpms instead of at 3k rpms.

It does to an extent. If you have ever been to ffw you will see everyone of the guys running fast cars with their lab tops out after every race adjusting crap. The dyno is generally a base line but for true tuning you need to data log on the street or track and adjust from there. That's where you will get your best tune for all around performance.

For future reference, can I expect the same arbitrary commentary if another two similar parts are being compared for measuring power output?

Yes, the original topic was comparing the two intakes to see which performed better. Where it went astray is difference of opinions of different driving/racing preferences.

You mentioned dynos. Dynos are merely a tool to get a car tuned. But guys like WBT are constantly tinkering with their own tunes to optimize the set up for the track. Where the dyno subject loses focus is where people use the dyno as a measuring stick for performance. Peak numbers mean SQUAT.

Dyno numbers can be manipulated in many ways on a dyno be it settings, load or whatever else have you. A number of other things can effect it as well, weather, trans type, gearing, convertors and so on.

Just because car A makes more power than car B, doesn't mean its faster. There are other factors involved, suspension, weight, driving style, auto vs manual and so on. There is FAR more to it all than just peak dyno numbers.

It's a moot point really. You can dial in a car's system for a particular track and use the same setup and be less effective at another track. All things being equal, tires, LCAs, gearing, shocks, transmission, cage, harness etc, would you prefer to have more or less power than you have now?

You forgot the larger plenum, especially in the rear, which provides room for the full bellmouths on all the runners, which the Boss does not have. This is the most important thing.

Well I haven't drag raced my car since June of 2012, but I made some 180 MPH runs on an unprepared surface which other than being rougher than the typical highway is no different than what you're talking about. Lots of blown cars couldn't keep up with me in a full mile. Now be careful, remember what happened the last time you mouthed off about how you were going to beat everyone.

If you guys want to get hung up on dyno numbers no problem. My car has never seen a dyno and would probably make around 250 at the tire but it has run 10's at every major track in Texas and has done so in every season of the year.

I'll stick to datalogging and track testing under real world conditions to evaluate effectiveness of performance parts. :waytogo:

I agree with everything you are saying.
