Lets talk Turbos...

Okay, many of you know that for the last two years I ran an Aerocharger turbo on my 80 inch Harley. A stock harley will produce about 50 horsepower and 60 ft-lbs of torque. Bolt on a turbo and instantly go to 100 horsepower. Thats double!! The nice part of a turbo is that it is smooth power. It is not violent like nitrous...it does not break parts. At 70 mph you are only producing about 1 lb. of boost. However, open the throttle and hang on - the power just keeps building.

I admit it. I have an addiction. I want more power! I dont need it, I seldom use it, but oh mama! I want more... Some of you may understand.

So how do you make more than 100 hp with a turbo? Easy!!! Flow the heads, turn up the boost, add more fuel, and hang on.

After having my engine builder Woody from Wildwood Performance in Pompano Beach, Florida flow my heads, I usually ran at around 130 horsepower with 11 lbs. of boost. Not enough!! Turn up the boost to 20 lbs., add buckets of fuel, and up to 165 horsepower I went. Wow!! Now were having fun!!!

Oops! Did I mention a few broken parts??? Um, yeah...belts, clutches, headgaskets, tires, etc. As a good friend of mine Buddy Parrot (yes, the Nascar guy!) once told Sandy: "When you break records, you break parts!!" Hey, if you're gonna play, someday you're gonna pay!! What's a few dollars for parts?

Want more horsepower? Add on an intercooler, a bigger cam, more compression, and yes - an 80 inch motor will produce over 200 horsepower at the rear wheel!! It happened in Daytona at the 2000 AMI Brute Horsepower Shootout.

Will it do it on pump gas?? Hell no!! Will you get good fuel milage?? Hell no!! Will you let just anyone ride it?? Hell no!!

Okay, the bottom line; a turbo on your Harley will make your life lots of fun, and it can be very reliable, if you don't get the bug. Run it as it comes in the kit; then passing cars and trucks, climbing hills, and leaving your friends in your dust is fun and easy!

Still want more power? Yeah, so do I; so I guess I will just have to put my turbo on my new 120 inch Merch motor!!

Can you say "200 horsepower??"

Speaking of turbo motors, here are a few dyno runs showing what they are capable of:
