A new guy just opened up here in town with a Dyno. The Place is Called DynoJet or something like that...but they have a 1000hp/tq Chassis dyno that is built into the floor. I am going to call and schedule a time slot for me to get in there and hopefully get some tuning done while im at it. Check out my sig to get my mods list and tell me what you guyz think i will turn. I am hoping to somewhere around 300 at the wheels, maybe a little more or a little less.

 

I wouldn't expect much, if anything over 300rwhp.

Good luck.

 

I'd guess around 290, go find out!

 

Should get at or above 300, but it will probably take a tune to get there.

 

My buddy has the same mods you have and Murrillo Motorsports of San Antonio Tx tuned his and pulled 322 to the wheels. I dont know what the torque was.

EDIT: I talked to him and he doesnt have headers... just stock manifolds.

 

you won't be quite at 300. 2 mach1's dynod during our dyno day. one had just a catback the other was completely stock
both were in the low 280s. i'd say 290 for you.

 

So headers and an X will only give him 10 hp? Come on now. Have you been hanging out with the nun in my avatar?

 

My friend had '04 Mach 1, 5-speed, pro-chamber (no cats), series 40, tuned to DIABLO Predator, K&N intake and more. After playing with timing and fuel on a dynojet, he got like 299 RWHP and never could squeak it up to 300 RWHP. This was with several pulls in hot weather on a dyno that I later found to possibly be optimistic. I think that you may get a little less due to cats and you didn't mention tuner or not. My friend was pulling with zero cats which flows really well as you know. Hope this helps.

 

yep. i only got 6RWHP from an X pipe & catback. maybe another 5-10 for the LTs.

 

Everyone needs to get it straight LONGTUBE headers on a n/a 4.6 are dyno proven atleast 20 HP!!!!! We've been threw this time and time again ! Its a fact of life. No 5-10 BS, 20 !!!!!!
