Default Horsepower quest!

OK i know this is old but with the combination I'm about to descibe how much horsepower could I see in my 08 Nightster?

I'm having 10.5:1 pistons put in and haveing the heads ported and polished. It will have SE 575 cams,SE Rollor lifters and rollor rockers. I'm buying an RB racing LSR 2into1 pipe and a SE tuner. I hope I remembered it all as I have alot to think about on this build. I know its probly not going to happen but I'd like to get 100hp out of this bike someday with the stock displacement. I hope some of you guys that tune bikes will chime in and let me know what kind of tune I'll be needing. Thanks

Turbo isn't what I want not to mention Turbo would be my last choice. Just like a street strip car if i were to go boosted I would do a supercharger setup first. Just my .02 though. Thanks for chiming in though as i love to here different opinions on things like this.

1. you are good for at least 80 hp & torque.

2. For 100 hp you need to talk to NRHS. They have gotten 100hp at 7k rpm with their 1250 kit & other goodies. Most stock bore 1200s get in the 90s for hp.

IMHO: get your flywheel ballanced & go to the extent of buying the correct ohm wires for your coil, etc.

Yeah I was going to go with an 88ci kit but I decided I wanted to get a Street Glide next year so I didn't want to use up my down payment for the Glide on my Sportster. NRHS said they did a full on stage 3 88ci kit and it cost them $5700 for their cost! I wanted it but it's just to much for me right now! I'll upgrade someday!

So why didn't you pose this same question with Dan @ NRHS?

I know you said your not interested, but it always makes me cringe when someone says they would do a supercharger over a turbo...

I own a turbo'd car (1987 Dodge Shelby Lancer # 149) and I have to say it is the most fun I have ever had in a vehicle. I bought it for 1500, with a few upgrades I was beating 40,000 dollar mustangs in the 1/4. Did I mention it only has 4 cylinders? Turbo's are easy upgrades if you know what your looking for. You can dig a turbo out of the Junk yard determine if it needs a rebuild or not. have some piping fabbed up, larger injectors, a new tune and voila! low psi and probably 40 + more hp (depending on conditions).. You don't need to buy a brand new 10,000 kit, just do some research and the leg work on your own and you can save 1000's..

...sorry back to topic.

I'm not a turbo fan...

They have lag and they are a BITCH to install ESPECIALLY on a custom set up. there's more parts to a turbo and they run off the exhaust witch means more fabrication and more of a PAIN IN THE ***.

they do sound cool tho.

What does yours do in the quarter?

Have y'all ever looked into the price for a turbo or supercharger? The in the box price is pretty expensive not including getting it installed and running right.

It would be cheaper to just do the 88" kit.

Turbos are WAY more expensive than S/C. Because they are more complicated and have more parts.

When I had my Mustangs I was going over my options and I couldve gotten into a nice centrifugal or roots type blower for around $3k. A turbo...about $6k...and a ton of labor costs.
