I'm not sure how old the thread is that I read on MB forum, but Evo sports is claiming to have a stage III power upgrade for you SRT6 guys, and if your crazy enough to put 411 hp to your cranks, thems the guys to talk to. Come on DOOO EEET!!

Why? When we already have a forum member that has just over 400 at the crank?

He's not even at stage three yet (from Speed Innovation)... at least I don't think he is. Pretty sure it's stage two now.

 

and for about 1/3 the price i believe.

 

What did SI do to get that much out of the engine. Was the ratio tweaked at all?

 

Try here and here.

Read up... enjoy...

 

lol, you still are convinced that you can change compression ratio by turning a switch or something eh?

 

how much was the 400 hp upgrade from SpeedInovation???

 

$3,400 installed.

 

$3,400 installed? What is this upgrade? No way I can get my SRT-6 over there. Is this something I can get installed out here in Chicago?

 

If you purchase the performance package and send the ECU over our way - then definitely.

 

I got my buddy's SRT6 to a 12.5 for less than $2,500. Thats approximately 400 hp. I got mine to a 12.6, for less than $900. A little know how goes a long way. We have the top two spots on dragtimes.com, see the dragtime listings for the mods and video...

 

Really? Wow, that's very impressive for the amount of money you spent.
Did you do all the work yourself or have a specialty shop do it for you?

Anychance you can post what modifications you made?

 

Yes!...please let us know.

 

Check out dragtimes.com. I did all the mods myself. The top 2 SRTs in dragtimes are mine and my friends, both of which I modified, the only difference in my friends and mine is I installed the evosport pulley upgrade on his and not on mine yet. I think his will actually run 12.3's with a perfect run.

 

hey screaminjoe, what can you do to a na crossfire, besides cams?

 

Don't waste your money on cams. An exhaust, K & N's and ECU upgrade from Renntech, Evosport etc., will get you to low 14's or about 260 hp.'

I got my buddy's NA coupe to a 14.3 doing the K & N's, my own custom exhaust and fooling the stock ECU with potentiometers to connected to the MAF, intake air temp sensor, and coolant temp sensor circuits.
