Engine Mod Question
I was looking at the new Screamin Eagle catalog. They show an engine mod kit (part 29774-02B) for a 2006 Dyna that will take it from 1450cc to 1550cc. The interesting thing is that the increase in torque and horsepower are incredible, like 25%. And it states using stock pipes! Can anyone confirm these type of results - especially with stock pipes?

RE: Engine Mod Question
I believe the SE stage I big bore kit also includes the air cleaner and hardware....that's where it's getting the most power from, not the increase in 100cc's.
If you check out the stage I kit ( NOT big bore ) just the SE air cleaner and hardware, I believe it will show that.
The cheapest and easiest power for your money is the air filter and hardware.
The SE slip on mufflers only gave me 2 to 5 HP on my 2005 FXDCI.
I have a 2005 FXDCI (stock is less HP than a stock 2006 )
with the SE slip mufflers
SE stage I big bore kit (1550 cc's )
SE SERT and Dyno tune now 80HP & 86TQ
still running stock cams....which will change this winter to gear drive cams...that's why I did the SE stage I big bore kit and not the SE stage II big bore kit which includes the SE 203 cams.
hope this helps...look st the increas you get with just the stage I kit air filter and hardware only
hope this helps

RE: Engine Mod Question
It seems reasonable considering pipes+AC plus a good remap will get you right around 70Hp, 70TQ.Also theres a good thread around here somewhere demonstrating that a similarly equiped TC88 will get you approx the same HP and torque as a stock TC96.PS I dont have a Screaming Eagle Catalog so what's HD wanting for this Kit nowdays?

RE: Engine Mod Question
I just checked the HD website..
The SE air cleaner kit for $139.00 takes you from stock 59HP to 70HP. that's 11 HP for $139.00....that's the cheapest HP you'll get for your bike....the next 10 HP comes from the SE mufflers and stage II big bore kit.
BUT getiing the AFR air/fuel ratio is the key....
taht will take someting to remap or alter your EFI/ECM

RE: Engine Mod Question
I think if you are going to open the motor up, skip the big-bore and go for cams.
You will gain more power from the cams and you can save the big-bore for when you need to freshen up the bore.
Also, it would be alot cheaper to just get the pistons and have your stock cylinders bored out when they need it.
A good port job will help out too!

RE: Engine Mod Question
A stage I will get you a significant bump, as it is a necessary element of going up to 95" try it first and see if it is adequate. I've had 2 stage I bikes. If you are goin to 95 , save up and do it right, headwork and cams along with the stage I elements . From a labor perspective it is cheaper to do it all at once .
I have what is essentially a Stage IV torque 95" except I use an Andrews TW31G instead of SE cams .

RE: Engine Mod Question
I do not know if I would believe everything that the S/E catalog would want you to believe.
A good low-lift, high torque cam, bore the cylinders,and a good set of heads and you would be VERY happy. You wouldnever wonder if you did it wrong.
