Hi All,

I have done a lot of research into many different threads concerning pulley upgrades. However, I would still like to hear from all of you concerning similar mods to the ones below:

1. 15 with ECU and injectors CAI exhaust (injectors necessary? I've read somewhere that injectors with 15% helps, after all, JCW does it.)

2. 17 ECU injectors CAI exhaust (GIAC ECU mod good?)

3. 19 " (GIAC IS good, what about SC redline?)

My rig has JCW intake and injectors. I want to do a pulley, hence the thread. I like 15 but this may have made the injector upgrade unnecessary.
17 sounds like injectors are necessary, but not a whole lot of info about this mod with GIAC ecu.
19 and injectors GIAC is much talked about and gets glowing reviews. I am a little concerned about SC redline, so if ya'll can post how long ya'll runnin? Any other problems with 19? Heard a little about pinging.
HOW BOUT THIS NICE WEATHER IN CALIFORNIA?

 

I had 18,000 miles on the 15, and have put another 29,000 on the 19. No problems. I use M7 injectors on the 19, stock injectors were on the 15.

Have used Webb/Powerchip ECU for 40,000 miles. Probably go to Unichip for a custom dyno tune like SpyderX did.

I do change belts every 10k or so with the 19, because I'm compulsive...

I arbitrarily use 6500 as a self-imposed redline.

 

Thanks for the info.

Did you hear somewhere that you needed to change the belts so often?

 

Can't recall a specific recommendation re changing belts.

Just thought it'd be safer since there have been some documented belt issues on tracked cars. I do compete in auto-x in my car, plus occasional track days, so it gets pushed a bit, not to mention my street/hwy behavior...

 

Cool.
What rpm do you rev to when you "jump on it"?

 

As I mentioned, I use a self-imposed redline of 6500. The Webb will go to 7200, however.

 

Heh, sorry I missed that. I read the text from email and that part was below the screen.
