I don't know if this is the correct forum for this but here goes. I've been considering cams and cam gear for my next mod. So I thought I would take my car out and run her to see what her times actually are now. So I dug through my boxes and found my G'tech. I know alot of people don't like them but I think it's a good tool. I set out and did some runs, trying to learn how to launch a Focus with no lsd. It kinda sucks at first. I found the best was launching at around 3000rpms or so slipping the clutch. My best time was a 16.4 at 88mph in the 1/4 mile. Some how I had this magic number in my head 15.9. With the mods I have I was hoping for more than a mid 16 sec. run. I did spins the tires and I'm running like 40psi so I know that doesn't help any. I'm trying to decide if cams, gears and a tune by Wayne is worth it to even try and get close to where my spec v was when it was stock.

Work on launching it cuz with my set up now, and the temps is FL, im running 16.3. Albiet i was on a track where the traction was good....Cams, gears and a tune are the next "boltons" that you could do with out really tearing into the engine. You could easily get into the mid 15s with decent tires and launching at a track.

Yeah I feel it should be faster. The header and Flexpipe added the most go between my parts. Maybe with a little more pratice.

when i feather launch (letting the clutch slip alittle) from 4k rpms i get my 60' down to 2.3s from 2.4s and 2.5s and it also gave me my fastest summer time of 16.3 so far....

I'll try launching from 4K rpms today and lower my air pressure and see it that helps any. Thanks for the advise.

I went out this evening and did some more runs. I found that my best times came from launching at around 2500rpms. I'm now able to do so without bogging and with a little wheel spin. I didn't make my 15 sec. run but I did pull a 16.06 at 91.7 mph. Close enough for now. I did run into a problem using the g-tech. Apparently my focus will hit 60mph at the very top of 2nd gear. So as I shift into 3rd gear it senses the shifting of cars body and kicks into 60-0 mode. ( I don't speed shift) Which is to measure how fast from 60mph your car will stop. This screwed me up a couple of times. So I have to shift at a lower rpm to counter the effect.
