I'm about to take my sc400 to the track, any tips on getting off the line? Stock motor and tranny, just a BFI, Tune up, and suspension mods.

The tip is just to practice before you take it to the track. You need to know the smoothest spot where your SC takes up quickest. Flooring it at dead stop isn't a good idea on the SC, including brake torqueing. This will bog the SC down. First, take it easy for about 1/2 second, then flooring it. That's how I find my SC pulls the best. Also, try the full synthetic oil. I haven't tried to see the difference in launching by using full synthetic or partly synthetic, but I think full synthetic will reduce the friction to the minimal.

I didn't take my car to the track, but at 6 psi, I was able to beat easily the new BMW 335 twin turbo, the 2008 Infinity G35 sedan (306 hp), and the Dodge SRT-4 turbo. These above cars have the factory rating of around 13.9 second for 1/4 mile. Due to this experience, I think my car runs in 13.5 for 1/4 mile. I don't lose traction. After the first 1/2 second taking easy, the rear just zig-zags a little when I floor the gas. I run 255/40/18 Dunlop for the rear.

Well, I haven't been to the 1/4 mile, yet, but I'll share my 1/8 mile times. The best I've done so far is an 8.795. This, in theory, would put me into the 13.6ish range for the 1/4. See mod list in sig BTW.

I am currently on the stock tire size of 225-55-16. I was told my tires were spinning past second gear and about a thrid of the way down the track. Long story short, I have a set of Supra TT wheels on the way. The wheels will be wrapped with Sumitomo 275-40's in the rear and 245-45's in the front. Hopefully with more rubber in the back, I'll be able to launch full stall (2800 Dragon) at wide open throttle. Launching WOT would also mean 2-3psi of boost off the line. I currently cannot launch at much more than 2000rpm, half throttle ish and no boost.

Since the last time at the track, I've made a few other little changes. I tightened the trans kickdown cable a little for a firmer shift and I installed two additional (to the OEM one in the radiator) transmission fluid coolers.

I will be putting the wheels / tires on early this week and I will be posting some new times soon. Trying not to get too excited, but I'm hoping for something in the 8.3 - 8.4 range which, again in theory, put me very close to that 12-13 second border.

Has anyone taken their 98-00 SC400's to the track? I'd like to see a modified one get into the low 14's maybe even high 13's with the right driver.

Thanks man.

This is with a 1000 rpm launch on my 2800 rpm stall. I think I could do much better with traction launching at a higher rpm.

It was also 90+ degrees outside.

Also wouldn't hurt to get my headers at some point.
