  • 14.607 @ 96.33, 93 Beretta, internally stock 3400

    best_time_slip.jpg

    Managed this run somewhere around a month ago at the strip in Cedar Falls, Iowa.

    Track was a bit slippery and it seemed like every 5th run ended with fluid on the track. Made for slow going and hard to build a good rhythm, but I'm happy all things considered.

    2004 3400, intake, TCE 65mm, port matched plenum inlet, headers, exhaust, tune, spec stage 3, 225/50/15 Toyo Proxes 4 up front @ 25psi. 1/2 tank of BP 91 octane, full street trim including 8" sub & 2 small amps. Pretty simple rig really.

    Since then I've replaced the roughly 13 year old Mantapart cone filter with a new K&N X-Stream flow cone and have been thinking about a new fuel pump to replace the factory original unit.

    Hoping the track is a bit stickier next time as I think there's a 2.10ish in the 60'. I'll make sure to keep this thread updated.

    14.60 @ 96.33 for now...

    I really need to get into something smaller than a W but still 60V6 powered.... 14.6 in a w-body seems to be in the ~250HP range. with a L-body, you look to be able to accomplish the same with ~40HP less.

          i was actually thinking a LITTLE bit bigger than that...

          89-95ish N-body coupes catch my eye. I'm seeing listed curb weights in the 2600-2800 range depending on engine/options, which makes it ~500-700 lbs lighter than a W.

            I've had both, I just prefer my Cavalier over the Beretta.

              He has had this car for a great many years. It would be shocking to see him give it up.

                The 5spd helps knock a good chunk off the times. My old lumina would have worked much better with a stick! (and a tune lol)

                  Nice times! Haven't been to CFR in a long time, going to be in the neighborhood in a few weeks at a car show though.

                    240Z... with boost... :P Weight in the 2400 lb area, especially with a 660. Mine was about 2500 with the straight 6, turbo and a few other heavier things than stock, like the wheels I'm running... The aluminum headed 660 about 100 lbs lighter than the straight 6.

                    I remember when breaking into the 14s N/A with a J or L body seemed hard...

                    I bet a few suspension tweaks could get you into the low 14's.

                      I've got a few suspension tweaks in place, dumped the 13" baer fronts for factory sized parts again, car launches way harder and still smacks down mustangs and corvettes on the autox course. Rear suspension consists of custom spun 600 lb/in springs and Saab Bilstein HDs. Front is KYB GR2, Intrax and poly everything with FE3 30mm sway bar. The front suspension is going to the be next area of focus.

                      Last weekend I went out and ripped it up hard on long track autocross. Runs were on a .6 mile former go-kart track, each run consists of 2 timed laps with a 3/4 lap warm up/running start. Managed a time of 1:22.94, which will likely have the car a very solid top 20 out of 70+ cars once they release official standings. Beat all but 2 of the Corvettes by a nice margin, left 12-15 mustangs watching tail lights as well as all but 1 Fbody in the house and that one was running a procharger and Nitto NT-01s all around on some nice suspension. Considering this was my first day on new tires, I think I can gain another second and pull towards the top 10. Kumho Ecsta V720s FTFW.

                        Using any toe in the rear? Put .75 on my DD Beretta and it sure seemed to help in the turns.
                        Funny, that this car has been around for years and now I'm learning something about it.

                          The rear is as straight as I can get it, with the super stiff suspension and sticky tires it doesn't need any special love. With a bit of trail braking the rear end wants to rotate with ease, just apply the power and it goes where I need. I want to get some higher spring rates up front and some more appropriate struts, I had been pursuing a custom coilover and was in the process of building a set before I moved, but I'm not sure that much adjustability is needed. I think some 500 lb/in springs up front and having Koni custom valve a set of adjustables will be plenty.

                            LOL I went crazy and used 1.5 first. Way too much! Still say .75 would help, makes it feel like the car doesn't need a rear sway as much as it did before. Bet .5 would work almost as good. Shims are cheap. Just used full dials on mine, cutting them where the studs go on top and slipped both pieces in.
                            Sounds like the front will be very stout.

                            Oops, forgot to add that the .75 made it feel like there wasn't as much need for a rear sway. This is all with the MRZ shock tower bar too.

                              How's the performance of the suspension on your car? Since you mentioned that you used Bilstein for the rear and KYB for the fronts.
