I have about 1900 miles on the 96"---> 103" conversion, so I thought I would get a Dyno run to see what numbers the new engine is producing. I was a little disappointed as the results were 106 TQ/100 HP. (5th gear pull, SAE correction, SAE/5 smoothing). Any easy ways of getting more power? I was hoping for 110/110. Build is TMAN P&P, 777 cams, .030" head gasket, woods 777, woods lifters, SE pushrods, S&S roller rockers, Wiseco 5 cc pistons (compression calculated at 10.25 uncorrected), SE 50 mm throttle body, Rinehart 2-1 exhaust.

 

I'm no engine guy but...
I have an s$s set up. 106, s&s heads, rollers, 583 cams, and I was going to get the SE 50 mm tb like you. My builder said don't do the 50 mm that my performance would be less. S&S agreed.

 

If the seat of your pants is happy with the performance then I wouldn't worry what the dyno says. Some dynos are happier than others, numbers are that just numbers

 

Your not going to believe this but the Rinehart Pipe is hurting you. I don't know which one to tell you to go with but if your comp is around 10.5 I would of thought your TQ numbers would be around 120. I'm making 102 TQ on a 96" with 204 cams. To tell the truth it's all about the combo.

 

A supertrapp supermeg and a bit of time tuning it on the dyno might get you close for the least amount of work. Don't waste your time chasing a number, it only leads to disappointment.

 

#`s are a little low,did you get a flow chart? not sure of the different degree`s of T MAN porting.we do 4 levels of porting,for example with our street port,those would be OK #`s,for our stage II or III,#`s would not acceptable.i agree with the other post that says the pipes are hurting you too,ide do a super meg
