I have not posted in a while been busy deploying again. Now that I'm deployed again I want to get more done with the mustang this year. I am looking at cams as one of the main mods to get done. I am looking at the NSR type cams specifically the Comp NSR, Thumper, and FRPP hotrod versions. Of those three I think the Comp NSR, and Hotrods make the most HP improvement but of the clips I have listened to the Thumpers sound the best with the Hotrods a close second. I am sticking N/A and mildly modified at that no head mods, no internal mods just the standard bolt ons LT exhaust, 4.10 gears, intake, tune, UDPs, and Delete plates.

-Knowing all this which cams would you reccomend and why?
-Can I install these cams at home?
-Do I need any special tools especially on the thumpers which require phaser limiters?

Thanks

well you will probably get your best gains from the comp nsr cams. If you are wanting the lopey idle I would suggest the thumpr cams. Personally I dont like the idea of the Hot rods as they do not come with the phaser limiters. ....Alot of guys are installing cams at home and getting a tune from a reputable shop. You will need a spring compressor I think and a timing chain wedge. ....I am sure someone else will chime in that did their own cam install and fill you in. Best of luck to you and be safe while deployed.

Thanks 05 Roush, I am leaning away from the Hotrods I just wanted opinions since they seem to be popular, I was wondering how they didnt require phaser limiters but the thumpers did. I hope someone can shed light on the DIY aspect as I would like to not have to pay someone to do it for me. I think the Comp NSRs are the way to go for straight gains but I'm wondering how far off the Thumpers are in gains. I have seen claims of 25 hp for the thumpers and as high as 30 for the NSR cams I just dont know what to believe or if there are losses in torqe one way or the other.

If Ford Racing Performance Parts says you dont need limiters. You dont need limiters. There isnt a company with more access to information, mustangs, and testing then Ford Racing.

Not to mention the cams have been out for a year now with people like tribatek running them since day one. No stories of PTV issues. If it was a problem running hot rods with no spring or phaser upgrades you would have heard about it by now.

To answer your question the Hot rod cams do not have the overlap and duration that the thumpr cams have that is the difference. Its just a less aggressive cam.

On power, hot rods, thumprs and NSR can show similar peak gains. Supporting mods and tunes are going to make the difference. The thumprs can show a higher peak gains then others

The thumprs have the most low end loss

The NSR are the least low end loss if any at all and do not need a any tune. They are the only cams of the three that you can put it at home and drive the car with no tuning issues.

There is a write up in the how section of this website that pretty much explains it as well as it can be explained.

For streetability, MPG, and overall powerband I go with NSR stage II cams. I ran 12.6s launching from idle and powershifting. launcing from idle and running that is the point.

Between hot rods and thumprs, the thumpr's sound better, but for streetability i think the hot rods might be better. for a straight drag strip car i might go thumprs for the extra peak power they make over hot rods. But then i would be running some 4.30s. Plus no one has tried thumpr stage I cams yet. The sound would probably still be there without all the low end losses. Tough choice.

A google search will probably net you dozens of dynos on these cams.

Thanks Rich appreciate the response, I sent you a PM on this I think, you can disreguard since you are answering here, So for power and sound the Hotrods would be best, and for straight power the NSRs? You said the NSRs were best for self install not needing a tune so am I correct that the Hotrods need a tune, and if so I could get a bama or brenspeed tune for them and the install for the hotrods would be the same as the NSRs right? I LOVE the sound of the thumpers, I am just worried about bottom end losses, do you know the factory numbers on the stage one thumpers? I am getting 4.10 gears too so some of the low end will be off set by them I suppose. I just want to be sure before I pull the trigger on a purchase.

I want the best sound with the most power and least low end loss. As well as the least ass pain on install.

Yes the install is the same. For streetability the hot rods might be a better then the thumpr's i think. The thumpr's make more peak power.

Here is a dyno, stock cams, hot rod cams and thumpr cams.

Yes the hot rods need a tune. brenspeed wont tune for hot rod cams the last I heard but bama does.

green is thumpr red is hot rod

[07stanggt]

I mean look at the dyno with 4.10 your shifting at 6500 the rpms are dropping to maybe 5100rpms. The power band on those thumprs is pretty even up there. The thumpr is deffinatley the better race cam

[killermach1]

what is the difference between the thumper, and mutha thumper on your site? And could you PM me the member price for the Hotrods, NSR, and Thumpers please? Thanks for the info and the graph.

I'm not looking to race per say, I drive like an idiot so I may benefit eitherway but I would say most of my driving is below 5000rpm except when I get stupid. My car is for me, for fun, It will never see a track.

[Grabber523]

Hey Rich, what stage Thumper was that? You got any dyno sheets for the Mutha Thumpers (Stage 2)?

[07stanggt]

That is the mutha thumpr on the dyno. I havent seen a dyno on a stage 1 thumpr.

killer, Mutha thumpr is stage II, thumpr is stage I basically.


The price is the price on the site. no discounts. But, you get rewards points. You could order the cams and then use the points to get the phaser bolts for free. You need need cam phaser bolts for the install.

[killermach1]

allright here is the final question, given that I drive exclusively on the street and usually never hit red line which cam Hotrod, Mutha Thumper, NSR? Which would you guys choose if it was you?

[07stanggt]

NSR stage II if you want the idle ,hot rods

Rich speaks the truth about these cams, he is very knowledgable on all of the options you are considering. And you sound like you are looking for a set of cams that are right for the intended application, which is better than just listening to everyone just say "mutha thumpers FTW" or something like that.

Anyways with your statement about driving below 5000 rpm most of the time, maybe you should look at a set with the power curve a little earlier in the RPM's. Maybe the NSR Stage I's. No you won't get the lopey idle, no they probably won't make the best peak HP, but you might get the best SOTP improvement and better gains in the RPM's you drive around at.

Just some more food for thought. Good luck on your shopping.

Have a Safe deployment and God Bless!

Good advice really though people dont want stage I anything.

Its funny i test drove a 2010 yesterday. Its weird how smooth and strong that car felt for being stock. I know my car is technically a lot faster car, but its all in the rpms and driving it right.

I'm not people!? I got NSR Stage I Blower cams........................... from you. Remember? Just kidding. I am a unique person and tend to drive down a different road than most.

The important point is to get the right grind for the intended application, and it looks like Mach1 is on the right track.

[killermach1]

Thanks for the info all of you. I'll mull it over. Its tough part of me could care less and wants that thumper sound, its really tough wish there was no trade off and one cam did it all, but real world I got to make the decision between sound and performance.

Yea I remember. Thats what im saying a lot of people just want the biggest all the time. You were smart though.

[07 Boss]

Thanks, I try to think I make some educated decisions.

Hey, off the subject, I sent you an e-mail yesterday to radmustangs about adding some GT500 strut mounts to my order I'm going to put in, but didn't see them on your website. Do you carry those?

Let me know and PM me, thanks. Can you get a better price than me or should I just go to the dealer myself?
