Well I got the dynoport on early. It seems to increase power quite a bit. Also it is alot louder. During installation I must have messed up a coolant line. I have a coolant leak. That's okay though ,cause I will take it to the dealer to get it tuned and serviced. By the way if I was going to hunt a whole lot I would not put an aftermarket pipe on. sounds like a big weedeater. All in all though it increases power pretty good. Especially even when I havn't even touched the air screw and it hasn't had a tune-up in a year. Pretty pleased, except that there was no instructions in the box. Course it looked opened before. Next step (about Christmas) I will get the EPI clutch kit.

 

Thanks for the report. Do you know if you gained any top speed yet? On the weedeater noise, does it sound cool or irritating?

 

It's deeper than a weedeater. More of a Brap! It's pretty cool though. The more I ride it the more I like it. I turned the airscrew a little and got even better results. The power is smooth too. It still wont wheely very easy though. I guess that's due to weight. Already got my friend who has a 300ex scared. He put a bunch of junk on his to try to out run me. When I showed him he had this pissed off look on his face and he downed it every chance he got! HE! HE!

 

Also on top speed. My speedo has quit! Gonna get it fixed though.

 

Hoolio,
Was the pipe worth the cash? I have a 2000 Trailblazer that I plan on installing a pipe and clutch kit(as soon as I get it back togather). Should have my cyinder back Sat. I had to have it bored .50mm and I got my Wiseco piston kit today. I don't want to spend $300 if it does'nt change the power much.

 

Why did you have to have it bored out??? I am putting on a HPD pipe and silencerbut I won't have the pipe until Saturday

 

The engine started to "rattle" a little. I took it apart and sent it to the machine shop. The piston had worn the bottom of the cylinder and had "piston slap", which is what caused the rattling sound. I could'nt stand that noise so I had to have it bored and get a new piston kit - nothing to do with a pipe or clutch kit.
