This Lexus IS300 started gaining on me & I could tell he was pushing, so I went for it, but my engine temp was at 2 bars. After about 7000 rpm the fuel cut off and the engine sounded like it didn't like what I was doing. I'm assuming this is preset in the computer, but did I do any damage or is this just a safeguard?

PS-- I did a search & found a post about this but it was missing or something so I couldn't read it.

And back to the lexus-- at the next light my engine heated up. He wanted to roll so I went for it. We stayed pretty close until I got up to vtech, where I just kept going and it was like he was standing still. (I didn't do a hard launch b/c it wasn't worth it, so it took a while to get up there). I slammed on the breaks at 80 and he kept going, but gave me 2 honks knowing he was BURNED! haha what was he thinking...

 

There are a million posts about this. The car won't go into VTEC until it's warmed up, which is rougly around the time you get 3 bars. You didn't hurt anything. It's like the rev limiter at 9k. It tries to save you from hurting anything.

 

rev limiter

 

it's God telling you to slow down

 

haha and you're telling me that with a supercharger in your car!

 

I have also killed and IS300 before, really easy. BTW, I always try to let things heat up pretty well (longer than just 3 bars) before attempting racing or hard driving.
