Hey guys I have a 2005 srt6 with 66k miles. It has a custom dcai, and a custom exhaust. I'm just wondering whats the next step I should take to increase performance?

 

Best bang for your buck is to get the cai, 65mm supercharger pulley, and a tune from eurocharged. Later on, you could get needswings intake manifolds for another chunk of change. Now if you have the money and want to put more work into the car you can get a 62mm supercharger pulley or the 185mm crank pulley, but with both you are going to need fuel(pump, lines, injectors), cooling(isolation kit, supercooler), and traction(wider tires, limited slip differential) upgrades. Headers and exhaust don't do much on these cars. Just remember that the more you do to the car, the less reliable it will be. Decide whether you want a reliable, street car or a fully built, less reliable track car and go that route. Also, I'd recommend an oil catch can for general intake/engine health because the stock pcv system sucks. If you get a smaller sc pulley get a pulley saver/belt wrap kit and you could get a scatter shield to help minimize the damage should your aftermarket pulley decide to break.

 

The more you do, the less reliable they become?!?!? Only if you don't know what you're doing. Look at the signature below and try to tell me the car isn't reliable....ha!

The intake is usually where everyone starts, then pulley and tune. I don't recommend crank pulleys as they turn everything too fast. Supercharger pulleys only speed up the SC, nothing else. Eurocharged or InMotion for tuning. Anything after that tends to cost about a grand per mod.

 

The ASP 178 crank pulley comes in a kit that includes new belt, water pump and idler pulleys to slow them down. The only accessory that suffers is the alternator IF you spend lots of time at redline…. like me. The supercharger pulley is cheaper and easier for sure. The instal for the crank pulley isn't for the faint of heart. Watch out for cheap S/C pulleys. My first pulley was a 65mm aluminum Code3. It didn't last a year. My advice would be to avoid the aluminum ones.

I was referring to power adders. You have a 65mm pulley, cai, tune, manifolds, which is what I recommended to him. I have the same stuff, except I don't have the manifolds yet. Your other mods enhance your power adders, which is what you want. I was talking about adding more power through the 185mm, 62mm, stacking, etc. I see threads all the time about not being able to get timing or a/f right with these pulleys. I don't see this with people that just have the 65, cai, and tune.

 

Lol I have personally found the more i Mod and run the car the more reliable it is lol... ive had the car for 4 years and have put about 50,000 miles on it and the only mechanical problem i have had was valve cover leak and bad motor mounts. Ive ran the 65mm pulley, DCAI, big manifolds, catless downpipes, supercooler, killer chiller,ecu tune, teflon y pipe for 3 years and seen much track time and made 361whp and 361wtq on dyno on hot florida summer day.. my car now has the 185mm pulley, 55 fuel pump, 550 injectors, bigger ic pump and besides running rich i have no problems! I also assume the car now has close to 400whp.. it has that setup for 5 months and no mechanical issues.. oh and it has 105,000 miles on the clock! Headers and meth kit would be next options after bigger crank pulley!
Like Chuk said.. be patient and mod it right.. it will last

 

I now have 90,000 miles on my extreamely reliable SRT-6. All the mods only helped me get the miles faster. Only major problem was a intercooler coil leak. All SRT-6's will experience this wheather modded or not. Squirrel Crusher

 

Squirrel Crusher.. how are robs headers? Power or tq increase? Change in exhaust tone ?

 

So...we can expect the intercooler coil to leak? I took a good hard look at the one we reinstalled at 75,000 and it showed no signs of impending failure during the supercharger changeout.

 

I believe that adding Rob's coolant separation circuit very significantly reduces the PSI (pressure) that the intercooler must withstand for no good reason. It was for this reason as much as better cooling that I installed this important, cheap and easy mod.

 

^^^^Excellent suggestion and a valid point made. We have two SRT-6s with them installed, no IC leaks in either car (47K & 85K). And the coupe gets run hard all the time.
