With the mods in my sig how fast would you say my car is in the 1/4, 0-60, and how much HP would you say it had at the flywheel or whatever not the wheels... well the wheels too.

i would have to say that you prolly would pull a 16.2-16.5 in the quarter

1/4 mile: anywhere for 16.3 to 15.9
0-60: 7-8 sec.
FWHP: 150-160'* maybe just get over the bump and hit 170.

These are just my $ .02 based on what Ryan use to have done to his car.

As for 1/4 mile it just depends what track conditions are, weather, track prep. of car, and how well you know how to launch your car.

I would say low 16'* on average.

Wow what a slow car lol. All these mods and my car is still in the 16 second range. Is it mostly a weight factor that makes this car suck? Its ok I suppose all I really need is torque for them short street races rather than all out 1/4 mile races.

15'* are possible though. A few here with 93'* have gone under 16.0.

It aint bad for a sedan with those mods. Not until you drop a good couple thousand will you start to get 1/4 times of 13'* and 12'*. Just think of all the other Bonnevilles out there that dont have any mods, along with other sedans, so put it in that perspective

Remember, he'* not supercharged, so even with a couple thousand dollars you're looking at 14s, maybe high 13s. The fastest Series 2 NA car from Intense only runs in the 13s, and it'* a Grand Prix. If you want speed, look into an L67 or else an NA performance rebuild with a stroker crank and high compression. But Twister'* right; think of the stock Bonnevilles out there right now that you can beat!

performance is a costly thing... thats why my car is still stock

so With my 95 series too with the rice pipe and k&n cone, flowmoaster muffler, and high flow cat. I should be able to pull mid 15'*-15.8????
