Default 11 second STI, 1st time @ the track, stock clutch

THIS WAS ON 27PSI, C-16 This is my as of todays times: (this is now my 2nd time, 2nd 1/4 mile event, 2nd day even trying to launch the car)

4th run (Best For Now RUN)
r/t---.880

1/8---7.423
mph---99.49

mph----126.70


2nd run (BEST 60' )
r/t---.274
60'---1.607
330'---4.815
1/8---7.428
mph---95.90

I was robbed they closed on sundays event. I never could end up getting everything together all in one run. My best run wasn't my best launch. I honestly believe that I could get a 10.9 & if not that at least an 11.1, this was done on street tires with 340 treadware, They sucked out @ streets of willow last weekend (road racing). This car's quick, I was worried about the clutch but NO sign of slipping or smelling even the littlest bit.

I saw you run on Saturday. Good job man. I was the WRB bugeye runing mid 12's. Are you going to make it to the next street-legal event in Fontana on Dec. 6th? I hope to have my ATP3076 on by that time and would love to line up against a rotated 30R. My best was 12.04 but i expect 11s with the turbo upgrade.

sweet man that sounds good, Nice motor btw, yea I would like to use VP's C-16 next time to see what that does along with some better driving skills by then (launching wise). My car weighs 3166 with me and 3031 without, this was with 1/3 tank of gas. yes I know I'm a lightweight. I love my rotated setup, pulls very hard after 3800, I would like to get a 1.5-1.6 60' next time.

you should be shifting earlier, look at your dyno sheet and see where you start to lose power, shift

also you can use a buddies or your own gtech pro, when you start to see your gforces drop off, shift

my dyno sheet says my peak hp is @ 6000 rpm and my peak tq is @ 4250-4300rpm, and when I shifted into 5th, to me that seems like an overdrive gear too like 6th, it bogs a little everytime I shift to 5th no matter what rpm I go to in 4th. I will try some different stuff on dec 6, starting with VP's C-16 and maybe a 27 psi tune

This shouldn't be happening, you need to log your car to see what is going on.

Great run! That trap is pretty sick though, so you know you got some more in it.

Well first you would need to know what is happening. It may be hard to dissect anywhere but at the track due to the speeds where it occurs. I do know that 5th isn't an overdrive gear, even then I have ran out 4th in my LGT to 5th with is an overdrive like gear and there is no hesitation.

My first thought since 5th seems to be the closest gear to 1:1 is that the load spikes and timing is being pulled.

I may just be trippin, Again I am new to this car kind of (since march) so maybe its just the 6 speed thing, Im sure the tune is fine, Its just weird shifting to 5th and expecting a powerband full of power, but trap I've heard by many so far is amazing, so obviously its just me, but thanks you guys for the advise.

Not sure, there is really no weight reduction done besides mods on the car compared to stock weight of those taken off mods. It has always had me fooled to wondering where like 300+ pounds went, I dont argue though being satisfied with what I have , I guess when I do weight reduction it will be even more surprising. It was weighed at West End when I corner balanced and had it aligned which was after the car had c/o & camber plates put on. Thanks you guys was a good day. I had a blast

I heart your trap speed. I've only been to the strip on two seperate occasions for a total of 12 whole runs but from what I've seen its hard to get everything to come together on the same run. I have runs with awesome launches and missed shifts or plain ole retardedly good traps(for me) but the rest of the run looks like doo doo. I'm sure all that comes with practice and with no doubt your times will improve without changing anything but the amount of seat time you put in at the strip.

Thats agreed, At first I didnt even know where it ended at & im sure I let off thinking it was done, and I was really surprised at a different 12.0 run that I missed 5th and bogged hard on the start. I really want to go out next street legal, will probably see you there

My guess is pulled timing with redline shifts. Was this car tuned on the road or a dyno?

can you log your car? the "bogging" in fifth is probably the target boost and/or wgdc tables. Jon probably lowered them a bit at the lower rpm to keep you from overboosting in 5th/6th gear. And he probably just guesstimated since i doubt he ran your car in 5th or 6th on the dyno.

And you should definately be shifting earlier in the higher gears. Take 1st-3rd to redline, then each gear you go up after 3rd gear, shift earlier....way earlier than 7400 rpm. You should never even be going out there above 2nd gear. There's no point.

You can look at your dyno sheet, but that wont tell you the whole story. Log your boost in 1st, 2nd, 3rd, 4th, 5th and you'll see what i mean. Most turbos in this range have a nice fat powerband for 2500-3000rpm after peak boost....so lets look at some shift points.

In first gear you probably wont hit peak boost until 5500rpm or later. And first gear is so short that shifting a couple hundred rpm earlier/later shouldnt really hurt your time. So shifting at redline is fine.
2nd gear you should hit peak boost around 5000rpm....so again just shift at redline.
3rd gear you should hit peak boost around 4500rpm...so again just shift at redline
4th gear you should hit peak boost around 4000rpm....so 4000+2500 = 6500rpm. So try shifting around there. Also since you're making peak hp around 6000rpm shifting at 6500 should keep you right in the meat of your powerband.

1st and 2nd I would always take to redline. 3rd and 4th are the important ones. You may want to try shifting earlier in 3rd gear too.

And just to reiterate, dont go over 7k above 2nd gear....theres just no point. Your power is dying off so much and your cylinder pressures are going up so knocking at 7500rpm is really bad. Your motor will thank you for not thinking its a high revving honda.

Nope....i was just on the dyno with my 6spd in my wrx at hb speed on thursday. all 4th gear pulls. Same was done with my sti at dynocomp, hb speed, mavrik, harman, gruppes....

wrx's are done in 3rd....sti's in 4th. At least those are the most commonly used gears.

If you dyno'd STi's in 5th you'd be going out to ~130-140mph on the dyno

yah, it sucks having to baby it into fifth...right when you are about to pass the line

have you ever dealt with shift knock? (vaus brought this issue up to a lot of folk)

god i want to get tuned at the strip...

Yes I have, especially with FMIC setups that tend to bang around in the engine bay causing false knock. This actually happen to me at the strip this weekend, it was pulling up to 8 degrees of timing (cool side banging the battery). After I found the problem absolutely no troubles and mph picked up by 3-4mph and times dropped by a .5 sec.

Vaus actually posted some very helpful information in regards to shift knock.
