Great numbers! Any idea what kind of power your putting down?

[M.K. STI]

well i was dynoed at autommasters and there dyno is rated the 3rd lowest rating dyno in the U.S.i put down 221whp,and 245wtq,and was told to add 20% to those numbers and thats where i should be at. so im assuming about 265-270whp,295-300wtq.

I'd try shifting before 7k on every shift....your are def going slower by shifting after 7k

[M.K. STI]

if you don't mind explaining how that would would be great.

[BillFromTR]

Post up your dyno sheet, you'll be able to tell if and when the power drops.

[silverex]

the power is goin drop off no matter what with a vf39/43. Any over 7k is def too high

I messed around with shift points and even shifting at 7k was too high. Most people that run fast times with a vf39 are shifting around 6500 or earlier. Shifting fast and/or flat foot shifting helps alot too.

[BillFromTR]

Typical VF39 dyno sheet


It starts dropping dramatically before 6500

Aftermarket turbos usually hold right up to redline

[silverex]

^Yep. Thats a normal curve for a vf39 on the first sheet. See the power starting to drop at 5500?....thats why you want to short shift it.

OP: Your not shifting into 5th right?

[C.J.]

with a 107mph trap you should beable to run much faster than 12.99, more like 12.6

car seems strong according to the trap speed so i say with more practice there is no doubt you will be running alot of 12 second passes as it sits now.

[M.K. STI]

no im not shifting into 5th.but its wierd b/c my first 1st&3rd runs i shifted 6800-7k and they weren't as good as my 2nd&4th (7200) shifts.and my trap speed seems to be higher when i shifted at the higher rpms.ill post my dyno sheet up and ill show you what my curves are.its just strange IMO that when i went higher in the rpms,my traps were higher and the times were improved.like i said,my final run i bogged the launch and hit limiter twice in 2nd&3rd and i still managed a 13.096.which is much better then my 1st&3rd runs which i would shift at 6800-7k .and same driving as always,very fast shifting and pedal to the floor.lol

[M.K. STI]

ok,here's my dyno sheet on the sti vf43(invidia g200 cat/bac,invidia v2catlessD/P,AP map on 93oct,and removed intake silencer)

track slips starting in order of runs

[BillFromTR]

It takes a 25hp nose dive at 6250. You want to shift around there.

[BillFromTR]

BTW did you ever put those BBS center caps in? And you coming to the meet this Thursday? Supposed to be nice out.

[M.K. STI]

yea i tried the bbs center caps,but they were too small you no wats funny,the honda S2000 centers fit.lol,i've seen a picture of it the other day.so i need to go around town and find an S2000,lol. and if i get out of work early on thursday ill be there!!! ill let ya know bill

yea i've noticed that also.i took the car for a ride tonight and plugged in my a/p,i hit full boost 17.9psi on a relative pressure rating and at 7k im bossting 16psi.so not so good,i need that protune soon.lol so i agree 6300-6400 should be my shift points.well,i need to hit up the track soon and get that 12sec pass in and ill be happy.my 60fts. need some work!!!
