I think a lot of the aftertmarket exhaust kits sound great, but for me the cam config makes a big difference in the way the cars sounds/runs. Is anything available or on the horizan???

$825.00 :shock: I was interested in cams until I saw that...jeez, how much for the installation would you guess?

 

I have to claimignorance when it comes to this engine. I think it is a DOHC design and I have no idea what is involved in changing them. My guess is that labor would be $500-$800??? Just a guess.

 

I believe those are re-ground cams, not new ones.

 

It's a SOHC engine fyi, I have no idea on install cost. And clockworks, before youre deterred, you should realize that in addition to the awesome lopey burble, BBR is claiming 100+ hp when their cams are coupled with ported heads.

 

100+ with Cams and heads? Intersting, too bad there has been no real news. Weren't they suppose to dyno the cams last month? And whats the word on heads alone?

 

Ha, yeah they claimed those numbers around 3 months ago and have promised proof "next week" ever sense. But being an optimist, i hold out hope.

 

Ok, I'm listening again.......

That's a lot of hp. $850 for the cams, and I saw a place that is selling ported heads for $1700. $2500 for 100+ hp. Beats a low boost s/c in terms of hp per dollar (comparing a Saleen s/c running at 4 psi).

Two simple questions from a newb. How much wear and tear do high perf cams and ported heads add to the engine? How do they affect fuel economy? I know the latter is a lame question, but........

About the lopey burble, that sounds awesome...but for some reason it makes me feel like it would make the car hard to drive as a daily driver, is this true? The reason why I think this is because when I hear "lopey burble", I automatically think non street legal drag racer.

Thanks for the info, I'm actually really interested...$6000 for an s/c which puts major stress on your engine is a bit pricey for me...but I could def. swing $2500...as long as it doesn't blow up my car...

Edit: Oops, it was BBR where I saw the ported heads.

 

Yeah, if they show a Dyno chart or something that has proof of this gain, it would definatly be the best way to go instead of a supercharger for $4000-5000.

 

I'll still take the SC!!

 

I may be 100% wrong, but I can't accept a 100 hp boost from just cam & heads. On a little engine like this, it just doesn't happen IMHO. I would need a lot of proof.

Yeah, thas definately a big jump, I think I'm going to call them up later and find out if there has been any developments on the head and cams.

 

I actually just called them, for got who I spoke too, but they said they would be on the Dyno this weekend and I was told to call back on Monday or Tuesday for some numbers. They said they are hoping for 380 or 390 with bolt ons like U/Ds, Charge Motion and such, but they are really aiming for 400 at the wheels with a stock bottom end. So this is definatly interesting if they get what their looking for.

 

The test BBR cams made 384 rwhp and 373 ft/lbs. This is in the florida heat too.

mods to the car:

-SCT Xcal Tuner
-BBR CNC Heads
-BBR Camshafts
-BBR Underdive Pulleys
-BBR Charger Motion Plates
-Stainless Works LT Headers
-Custom side Exhaust
-4.10 Gears
-JLT CAI

 

Not to mention, that test was performed on a Mustang dyno. Stock GTs register around 240-250 on Mustang dynos. So, the cam/head package + supporting mods netted about 130 rwhp, i'de say around 50 of which can be attributed to the intake/tune, long tube headers, and UD pulleys.
All of those mods could probably be had for less than 4k, so yeah ide say this is bang-for-buck competetive with the saleen supercharger (which you could always add later on top of this, reground cam profiles matching supercharger power-on and airflow characteristics would be very interesting...)

 

dyno sheet is posted in another thread.

awesome gains from heads and cams.

 

is it a full cam kit? valve springs ect ect??

 

Will BBR be releasing dyno numbers on their milder cams also? If I remember correctly, they are offering three different versions. I would be interested in seeing info on their heads combined with their next step down cam offering.
