Wow, go build a real turbo engine, then say that you can't have any overlap. Ever built any kind of a motor with a lot more options than hondas in respect to intakes, heads, transmissions, etc? With a honda you're limited to the 4 stock VTEC cams, or some people go for the gusto and run some crower turbo cams. I helped build the motor and maintain the car for a friend who ran NMRA drag radial for a little while. Figure around 1300-1400 horsepower from a single turbo and 360 cubic inches. The cam was custom ground from Bennett, who build turbo motors for a lot of the fast Ford guys. Duration was well over 300 degrees advertised and nearing 260 degrees @ .050, and the lift was over .700" at the valve. Only reason the car wasn't competitive was because it made too much horsepower for the tires. Leave off the brake and it would light them up, leave without boost off of the footbrake and it would load the tires up nicely and as soon as boost hit it would be like a skating rink. It made a **** load of power, and we were shifting the motor at 8500. All with around 270 degrees duration @ .050" of lift. But wait, that can't be! A GSR is only running about 230 degrees of duration @ .050, and <u>everybody</u> knows that VTEC cams have too much duration and overlap for turbos, right? Right? Considering that the extent of your turbo knowledge seems to be your attempt to turbo your del sol, you arn't really in a position to tell me that I'm going by what I heard or read in a magazine, that you know what plain fact is.</TD></TR></TABLE>
ahahha turboing my del sol wow...
now as a diesel turbo engine builder at PCE Diesel in san diego, i guess i shouldnt really know anything about that
sorry to give wrong information LOL,
plus i dont see where i said, you cant have overlap, i said its what you dont want,
the least over lap you want the more power you will make, its a basic principal of physics and math when it comes down to making more power on a motor, from what your accusing me saying " you cant have overlap on a turbo car" i dont see where you can quote me on that but from what your saying is the more over lap you have the more power you will make? why dont peoplpe just run without intake valves if thats how it is to make SO much power is to have massive overlap

Vtec motors will always make more power, pound for pound, no other independant variables considered. It's because the intake valves are allowing more air into the car. It's simple physics.
This may be a bad analogy but here goes:
You have five 02 molecules intake and five exhaust at once. During vtec, it's maybe 9 molecules intake and 6 exhaust..thus producing more power.

Re: (ILLICON3000)
Vtec has nothing to do with it at all. Its the fact that the Vtec HEAD flows so much ******* better. Vtec really only makes the car easier for daily use. B/c you can stay on lower cam profiles at lower rpm. You can always upgrade the cams in an ls(nonvtec) but it still wont flow as well, b/c of how the head was designed. Has nothing to do with VTEC making the power. I cant believe this misconception is STILL going on.
