What did you guys do that dropped your times that much?

TTBOOST - how did you pull off your best times ie Which gear did you start off at, which RPM did you start at and shift at in each gear, brake boost, down 3% incline, brake boosting etc.

Being I am going k24 BILLET 20 now I am wondering how to get the best time out of these turbos, especially down low where even my BILLEt 16's were not on full steam in 3rd gear starting around 37mph. By the time I hit 60mph my car was just getting into full swing costing time, so with these larger turbos I can see me having to hit 70mph before the turbos come fully on line!(costing even more time) Going to 2nd would only make sense, but two shift would most likely hurt more then help the time.

Any advise would be great!

Thanks

I usually start at 35-40mph in 3rd gear, accelerate to redline (being VERY carful NOT to hit limiter), shift to 4th as quickly and cleanly as possible and run up to the limiter in 4th. I seem to recall not having full boost until 3500-3700 or so with my 18g's/meth. I am usually at about 1bar by 60mph or so...brake boosting CAN and HAS given me about a tenth.. but usually netted me wheelspin, so actually slower. With 20g's, I would expect you to be a little slower down low, but marginally faster up top.
Oh yeah, I think my limiter was bumped to 7200 or so, but never made any power past 6500, but it DID help me get back into boost sooner...
Only 1 time did I ever equal my best time with 2 shifts..ALWAYS better with 1 shift for me...

 

Definitely wasn't questioning that.

 

Mike,
traction issues with a K16 + tuned car ?
his time sounds about right give or take a 1/2 second

 

Hey Marty...yeah, I had traction issues with my car with my K16 flash...not nearly as bad as the 18g tune of course...I never ran my car stock, or just flashed with the Pbox, so not really sure what the expectation was...

 

That's one of the reasons I went with 18g when they were trying to push the new 16 billets at that time..

 

So after all of this I still don't know what a stock 996 Turbo's 60-130 times are. lol

 

Flashed ECU is around 10ish.

 

My 997.1 was doing just marginally better with a supposed ECU tune and I was hitting shift spot on, getting traction etc

OP's time looks spot on for what he has

 

So a stock 996 turbo would be 11.5ish?

 

I see to recall a stock 996 Turbo is in the 11-12sec range...

 

When stock, my X50 was running 10-10.2s consistently (no decline aid !!).... 4th gear straight pull usually equalled my best 3rd to 4th quick shift times.


At the time, my car was dyno'd on a dyno dynamics at 380AWHP which translated to 475FWHP.
