ok heres what happened.....me and my buddy were driving home from work and i dropped my car into low and tires broke loose and i shifted up to second and third and hit 120 ish.......let off went around a nice rounding corner at about 75....i THOUGHT i was in OD for some reason and when i downshifted i went to second and nailed it...well to my surprise my car revved to 7k.....ouch...it was only there for a few seconds....well i let off and cruised to the intersection.....my buddy behind me in his car said that i had some blueish white smoke puff out for a few seconds out of one pipe....then it stopped...is this normal when you ove rev your car???? i got to my house and checked it and it wasnt doing it anymore......shouldi be concerned? the engine doesnt knock or use coolant or oil.....and its all forged with a sportsman block and only has 15k miles on it

thanks

very normal, when you get your valves floating and that much friction, you will get some burning of oil. itll be fine

Dude ! 7 Grand? I havent had a motor that revved up since I drove an RX-7.
I would guess it would be okay as long as you didn't make contact between piston and valve.
Nice looking car by the way.

Like Murdock said, it's normal to get that puff of smoke when you rev too high. That's why there's red lines

You must have disconnected your rev limiter. The factory rev limiter won't let it go to 7000 rpm.

FYI for everyone. Rev limiters do not work during downshifts. During a downshift, the wheels are driving the speed of the engine. The computer can pull all the fuel it wants,the speed of the vehicle and the gear downshifted to will determine the engine rpm.

So, everyone be careful on those downshifts.
