What do you think?

[gunracer]

Ok, I have a few friends of mine who have chargers, 300's, and magnums and when they heard me tell them what performance parts Im gonna put in my car when I got the money there first question was," how much up will all that help produce." and now they've got me wondering. What do yall think?

Ported lower intake maniflold and ported throttle body
inertia cams 1.1
big bully intake
jba headers
magnaflow muffler with blastin bobs dual conversion
and a diablo. That's all I'll be able to do I think with out screwing up fuel economy to bad

i'm gonna guess 35-45 at the wheels

^^^That's not a bad guesstimate, although you probably did the same math that I'm about to lay out.

Gunracer, some numbers for you to consider:

The Inertia cam alone is reporting 15-20 at the wheels (with proper tuning, of course). 5-10 wouldn't be unreasonable with the JBA's. probably similar with the intake, maybe. The p&p combo is good for between 10 and 15, based on posts by rwalshphoto, britishnate, and some others that have used these parts. The cat-back, maybe 5-10 again. The Diablo probably does the same 5-10, but it also gives us the ability to tune for the different mods. This basically gives us the "Synergistic Effect" we're all looking for where the sum of the whole is worth more than the sum of the parts. Just simple math says that between 40 and 65 rwhp is possible (using the lowest and highest advertised hp increases) with all these bolt-ons AND proper tuning (read: several CMR and dyno tuning sessions). Given that most of us haven't done this with simple bolt-ons, somewhere around 30-40 is probably a pretty reasonable expectation. Keep in mind, it's not ONLY about the HP that you'll gain. It's also about how the car as a whole responds to these mods. Read this thread about how the drivability of Ryan's Magnum changed with some of the same parts you're considering.

I will have some more objective results to share soon because I have a TB, lower manifold, and coated valve covers on the way. I don't have access to a dyno, but I'll be posting about the install and driving perceptions. So far, just with my Magnaflow cat-back, AirRaid intake, and Diablo: I love this car and I love my V6!

If you can, Dyno the car before adding the Mods, then Dyno after to see the exact performance increase........

Word of advice, let a shop do the header install......It is a PITA......especially without a lift!!!!!!
