I think I'm the only one with actual real world data to back it up, that doesn't work for a racing team or GM. And screw Brembo brakes. All they did was give another piston to the front calipers and larger rotors. They've aready had a recall. Convert to slotted/drilled brakes. I did. Was one of the best mods I did.



1. Reliability says what? I used to work for a Honda dealership service department. Go look into which engine is leaking oil. Also, show me who's on top in the Grand Am series.

2. That's because most people think that supercharging a 4 cylinder is stupid due to parasitic loss. Tuners tend to go towards turbo applications. Probably because turbochargers are usually cheaper than superchargers.

3. .90 lateral g is really crappy for any car from the factory. Sure does beat cars like K series Honda's and Ford Mustang GT's. Also, same format does not mean same parts. Have you heard of suspension codes like FE1, FE3, and FE5?

4. Take your own advice. I win. You're a tool.

take my advice again and read the whole page before post next time

TQ doesnt matter as much when your going 60mph...

Plus, vtec does not kick in until a few hundred rpm's before the Si hits the rev limiter, whereas the LE% has VVT that optimizes the valve timing across the entire rpm range. I think it's possible. Engine speed does not equate wheel speed. My 07 SS/NA is bone stock powertrain wise (and is a manual tranny) and ran just slightly slower than a newer Si sedan with exhaust intake. Only difference was the driver. This is based in track times the same night, so temp, humidity, etc is not a factor. My wife was driving the SS/NA that night at the track. She knows how to cut a good tree and be consistent. I was racing my 06 SS/SC.



fuel cutoff is 148 stock. can be removed with a tune.
