Rockers vs BBR Stage 1

[Walshyboy1220]

So I have been SEARCHING and comparing these two for the past couple of days to narrow the cams down to these 2. I just wanted to drop some questions by you guys becasue these two have really never been compared head to head, but more like BBR vs Hotrod and such.

Moving on,

I know that BBR focuses more on exhaust? Than intake is considered because I remember reading that the DR focus more on intake than duration that lift and exhaust?

Correct me if I am wrong however I dont want to spread any rumors.

Though, What power difference is between the two? 10 RWHP? 5 RWHP? I have come to the conclusion that BBR is a more aggressive grind then a DR as they give more sound but what is the trade off in power? Drivabilty? Is the BBR going to give you a better 1/4 time?

Also what is the trade off that you will expect to see in MPG's vs Stock with a Email Tune?

Thanks for all the future help fellas, I searched as much as I could and just wanted to confirm and compare some things!

My best time at the track with the BBR stage 1's was a 12.9@110mph with a dismal 2 sec 60ft. But it was only my fifth pass ever in the car. I can do better. I dont think you could go wrong with either cam, but have you looked at any comp cams? If your concerned about mpg the you shouldnt be modding your car! lol. My mpg sucks but I have 4.10s which doesnt help. Alot of people recommend atleast a 4.10 gear when adding cams, maybe some guys with 3.73's can chime in on that one.

 

[Greg Hazlett]

Are you a stick or automatic?

Are your headers shorties or LT's?

Which BBR stg 1 cams are you referring to? The newer ones that are from cores or the regrinds that you have to shim?

Do you want sound more or power?

I don't think anyone has ever dyno'd HR cams, removed them and then installed BBR's cams and did a back to back dyno comparison but I recommend you call BBR and talk to John as they carry both cams and have installed, tuned and dyno's both of them and can answer your questions.

3.73's and detroit rockers,jlt coldair with dyno tune,made 308hp 304tq getting 19.4 mpg, before with stock cams and everything else the same I made 306hp 326tq and was getting 22.4 mpg. I did have the stock 18 inch rims with the stock cams pull and 20 inch rims with the detroit rocker pull so dyno numbers are probably not showing true gains due to the extra weight of the rims.

Yes, I looked up Comp NSR Stage II's. As much as they are great they seem more like HR's to me and dont add the same power as other cams im looking at. I do about 60 % City 40 % Highway driving. Im going to stick with the 3.73 anyway to give me the advantage of the mpg's I will be losing but it is all in the tune however

I am a Automatic

I currently I am running, Edelbrock 1 5/8' Shorties but will be putting on JBA Longtubes when tax return season comes around.

I am referring to the billet ones not the regrinds

I am looking for a mix of both, the Detriot Rockers give to me better sound but the BBR seem to give more power and I just wanted to see the difference between the 2. If the BBR's make 7 more RWHP than the DR's I will be choosing them. I was also taking about DR's not HR's as they are a good solid cam for sounds they dont seem to make the same power, unless they are tuned to perfection

 

[Walshyboy1220]

07 Gt, Are you an automatic or a manual? Were your tire size different on the 20 inch rims? Im surprised it only made that much of any increase usually the DR's claim to add 30-40 RWHP. What was our rev limiter?

 

[07gt/csJax]

Manual and the roll out difference in tires was 33 revs per mile,rev limiter was raised to 6800.I was disappointed, was told that the rims caused the difference wish I had done a pull with the stock cams and the big rims just to see but I still have the other rims so may put them back on just to see.

didn't anwser question....tire size was 275/35/20 the rims are enkei lf10's, very very heavy!

 

[Blxcklist]

I have 4.10s and Detroit Rockers. Honestly if I had to get cams again it would definitely be the rockers again. They have perfect drive ability with no power loss. Honestly the car feels stronger all over especially the top end. And the car sounds like a beast now.

Sorry I don't have dyno numbers or anything. But you really cant go wrong with either of them. The thing that swayed me more towards the detroit rockers is the shorter lift.

.480 lift (BBR cams) on stock springs scares me. An extra 3 or 4 hp is not worth the extra wear on the valvetrain to me.

 

[07gt/csJax]

I have to agree with Loudnlow. They do have very good driving manners and the car does feel like it pulls harder than before not matter what the dyno says.Car gets looks while sitting at lights like they have never heard a cam before.

Wow you lost 2 RWHP and made 22 RWTQ? That sounds really off regardless of the difference of rim size.


Also I like the Detroit Rockers because apparently they dont loose the low end torque and the driveability is the same as if you were running the stock cams. I don't own them but thats what I hear.

I dont think that the extra weight of the rims would of casued that much of a hp loss. They weight gain is not as great I dont think. But I am also running 275 all the way around so thanks for your input. I also will set my rev limiter to 6800 as I dont feel like replacing the springs. Thanks for your input!

Thats all I have been hearing from DR's is that the drivilabily is great as well as the sounds. I am just perplexed as how there lift is below .450 and still give close to the same hp as the BBR's do. What is your MPG's with the 4.10s and DR's??

Also yes it does to me to, if I went wit the BBR's I would upgrade the springs as well but I would like to know if anyone had some dyno numbers of there BBR Cams with some usual bolt on's(CAI, UDP. Headers, Delete Plates. Etc)

 

[martinr69]

I have the comp cam mutha thumpr (127020) and FRPP 4.10 gears. I gained about 23.5 hp from my last dyno. But I would look at the comp cams

1st dyno in april of 2010 I pulled a 290 rwhp with 93 octane tune, jlt cai, o/r h pipe, flow master exhaust.

2nd dyno dec 2010 I pulled 313.5 rwhp with 93 octane tune, jlt cai, o/r h pipe, mutha thumpr cam, FRPP 4.10 gears, bassani mufflers.

So now I have steada under pulleys and delete plates coming. So when they are installed i will have another dyno pull to see how much hp i gained.

 

[Blxcklist]

Rockers lift isn't less than .450

 

[07gt/csJax]

Ford20 No I gained 2hp and lost 22tq, tuner said the way to explain it is on a dyno its like a 5gallon bucket thats empty is much easier to roll than a 5gallon bucket full of water which is true, but how much difference?...still have the stock rims I may on a dayoff just throw them back on and go see if it matters and how much!

I was up in the air about DR, hotrods and comp cams. I was told since my car is a d/d and I do take it to the track that the comp cams would be my best bet. I know Chris Rose recommends Comps for performance over sound.

Good call on the LT's, shorties are a waste of time and money.

Don't quite understand the tuned to perfection comment, these are bolt on NSR cams so there is not a lot of "perfection" to be had.

A 7 hp change can be seen from one dyno to another, 10 degrees difference in temp from one day to the next, etc.

I know you are wanting the DR's but with the HR's and LT's/catted H I gained 33 hp and 3 tq.

 

[Blxcklist]

I know for a fact the 127200 NSR stage 2s and the Detroit Rockers have very similar specs. Rockers just have a tighter LSA and more duration.

from what i read on here, people are getting pretty damn good power from the BBR cams whether they are stage 1 or 2. And it seems to me that the added bonus is the sound

Do you happen to have any track times or dyno numbers? Also any difference on sound compared to DR' (Assumption made by difference in youtube videos to person)

By perfection I mean that people either gain 30 hp or they only gain 20 or somtimes even gain 35-40. It seems like the tune is very finky on them or the cam is just hard to tune with your car even though its made by FRPP

My best 1/4 mile so far is 13.185 and best 1/8 mile is 8.399. Now these times are with D/A of over 1500'. Last time I dynoed my car I was at 322 RWHP and 311 RWTQ. Which is about about a 20 hp and 0 tq increase.
I can't wait to see how my updated Amazon Tune does at the track. The comp cams will have have the least aggressive lope than the D/R, hot rods or BBR.
