Finally got enough parts together to get my car running. I didn't have time to hook up the boost controller, so my runs were at 7.4 psi. Boost seemed to creep up to over 8psi from 7500 to shift point. timing at .5 bar was 20 degrees, and when it was at max boost it was about 18. A/F under boost was high 10's or low 11's.
,


now its time to up the boost and hit the dyno.

 

thats a odd slip look at one of my street tire time with 8psi
you have a lot more mph then me but look at your time and 60 foot ,with the same 1/4 mile time as me

 

what size turbine housing do you have

I have a .63 on the hot side, stage 5 wheel touched by Arturbo.

As for the timeslip, my only guess is that I bogged on 24.5 slicks. I launched at 5600 thinking I would get some boost, but it bogged to under 4000 and took a bit to spool up. your 1/8 time was better than mine too.

 

you have mph for low 12's if not very high 11's ,but you maybe short on TQ and only have high end hp and no midrange and lowend power

but you do have topend power

if u look at ur 60', then ur 330', and ur 1/8 mile. you can tell that you got out of hole alot better he did. It looks to me like he hooked a little(reason for the alright 60') but bogged well past the 60' slowing down the 330' and starting to catch up on the 1/8 mile.

Salt- Thats really good mph for such conservative tuning and boost.

 

That's a very conservative tune! Get that thing tuned on a dyno a it'll make a ton more power!!

 

thanks for the feedback. I plan to dyno this saturday If I can get the boost controller to work. Here's some more info. I filled up on 94 octane on a sunny 85 degree day. My intake temps were about 104 when cruising to the track. but they were about 134 sitting in the staging lanes. its a lot harder to tune turbo than NA so I left it pretty conservative.

whoever mentioned lack of low and midrange power is right. hopefully when I get the boost controller working I can get a little faster spool. I installed it today, but its going to take some time to get it to work. I am useing the AEM which has awesome control, but its not linear so I have to experiment with the wastegate duty cycle to get it even across the board.

 

i take it that's a gsr?? good times on such low boost..

 

Looks almost the same exact setup that we are putting in my car right now. Turn that boost up and run some 11's. Any internal work done?
