Thumbs up MAX $2,500. Best Mods to get.

OK! Ready to take it to the next level. I have a 2006 300 SRT8 with CAI, Magnaflow Exhaust, and a Jet Performance chip. I LOVE THIS CAR!!! Looking for low-mid range gains and a little more attitude. I have saved up $2500 to spend and wanted to get some guidence. I am in Houston TX and do not know of a good mechanic. I called around to various shops and did not get that warm fuzzy feeling that they new what they were talking about. Looking for some SRT8 specific guidence. Thank you in advance for your help. You guys rock...what a great forum!

Would it make "cents" to go torque converter, cam, and one of those custom tunes (Is that what a Preditor is?)? Not sure what that would cost drive out.

Peace,
Andy

Firstof all I would say get rid of the Jet Chip & get a Predator or Trinity tuner from DiabloSport. Then get a CMR tune somewhere. If you don't have a 180 Tstat get that as well (cheap). Thereafter some new rubber might be in order shortly.

See my photo gallery section. First name is... uh... Tim. I know... it's Goofy! LOL

but now there's the 300C Platinum and an Edelbrock SC Magnum SRT8!

Definitely get a predator! You'll love it compared to that jet chip. With $2500 you can get some good headers/high flow cats to complete the exhaust and cam your motor... that might leave you with enough for installation but unless you can install yourself that would probably put a just a bit over; not much though. Then you'd have to get a CMR tune for your car so it responds nicely to your cam. After that though your car would be insane
Then later you could step up and get some heads.

I'd get a Predator and CMR tune from Frank's Racing (I think they are in Dallas or Houston) for maybe $700-800. $500 for Magnaflow high-flo cats. That's only about 1/2 your budget but I bet will make a big difference. Use the rest for tires or fluid flushes and maintenance and maybe a couple appearance things like tint or halos or a grille. I've never driven a car with a torque converter so I can't recommend one, but I would like to try it. You could probably get one installed for $700? Got an oil catch can? Good luck,

Eric

Thank you guys.
I am sold on the Preditor and CMR tune for say $750. I will look up Frank's Racing (Thank you EricG). That leaves me with $1,750. What would you do?
I definately want to do what makes the most "cents". I just added new tires BFG G-Force tires, and am all up to date on maintenance. I do not have a catch can (Not sure what that does, i will look it up). I prefer the cars I hear that have a little more muscle sound at idle. As well I am looking for more low-mid range performance. It is already a beast on the highway and I just do not drive at real high speeds. I enjoy getting to 75mph quicker as opposed to driving 100. The old 6.1 Hemi is what attracted me to this car in the first place. Is it a cam that would accomplish that. If so, which one...any suggestions?

I want to thank you all for your thoughts and imput. This site is a great resource for a rookie like me.

I'd wait and see what the Predator feels like to you, it really does make a big difference in low end power. And don't quote me on that price for the tune...but it shoudln't be too much more. And don't let them tell you they can email tune your car - get it on their dyno or find someone else who is willing to spend the time to do it right. I'm sure Frank's will take care of you though.

And don't forget the Magnaflow high-flo cats, want to get those on before the tuning and they are worth it.

$1,750 will get you a cam, which will make a HUGE difference. You would need to do this prior to the CMR tune as it would need to be done again afterward. Next to nitrous and forced induction, it will get you the biggest HP gain. Other than that, I am in complete agreement with the rest. GL!!

^ what he said. Based on your other post on the cam and this one, it sounds like you're going for that musclecar sound/performance....a cam will definitely do that for you! From what I've read, a high performance cam could give you another 50hp++, especially if you get a CMR tune to really take advantage of it. FYI there's a guy in the Northeast who many people have used that only charges $450 for a cam swap (plus travel time if outside the local area)...check around to see if anyone from your area knows someone who will do it on the side for an inexpensive price like that...just make sure the person is reputable - I wouldn't want just anyone working on the innards of my engine. I shopped around, and a cam itself is around $400-500. I think there's a couple more parts you might need on top of the cam itself.

BTW, the shop near me charges $540 for a CMR tune...a Predator costs about $275-300 no matter where you go, so around $750-800 sounds right. A lot of times though you can get a package deal where the CMR shop will throw in the Predator with the CMR tune and save you a few bucks. If you do go for the cam, check with the CMR shop near you to see if they can do a preliminary email tune..the one here will do a tune that won't be ideal, but that will get it running safely until you have a chance to get it to the shop, and then they apply the cost of the email tune to the full CMR cost when you bring it in.

OK! I took the advise and visited Frinks Racing. Nice guys!
They looked at what my car had and advised me to do the following:

FRI Sparrow Camshaft
PAC 1218 Springs
Diablosport Predator
SLP Underdrive Pulley w/belt
Dyno tune

The whole thing is right on budget.
One thing they did not include was the high flow cats. After reading Eric G's post I think that is a must. They mentioned that my cat back Magnaflo exhaust was tack welded on and they seemed as if they did not approve. Also mentioned something about if I added high flow cats now, if I wanted to add heders at a later date, that they would have to come out. I guess there are different high flow cats depending on if you have long tube headers or not. I do not plan to add headers so not too worried about this. At this point I think I will save up for the high flow cats and do it all at once (May have to roll some quarters). Any thoughts on their recommendations??? Particularly on the CAM. They had an SRT8 Magnum there on the dyno while I was there that posted a 418/428 (I guess that is hp/torque?) with a similar set up...It had a CAI, Heads, FRI Sparrow Cam, Magnaflow high flow cats, Corsa (sp?) cat back exhaust, and a Predator Tuner. Do not know if that is good or not. It is really hot and humid today and I know that makes a difference. Please let me know your thoughts.

Thank you all for the help! This forum is awesome!
