87 TII stock turbo dyno

[antman0408]

Didn't know where to put this, so mods can move it into proper section if it's not suppose to be in this section.

I wanted to see what kind of power my car was putting down before upgrading from the stock turbo. There was a dyno day pretty close to me, so I was able to get two runs.

Engine: has about 20k on it since I rebuilt it
s4 engine, small streetport
stock s4 turbo
haltech e6k
550cc and 1600cc injectors, parallel fuel setup
walbro pump
greddy fmic
act pp and clutch
corksport exhaust


I dont have a real boost controller, just a homemade ball and spring one, so boost isn't consistent through the whole rpm range. Wish I had a better controller so I could have a more steady pressure. Peak pressure was 11.8 around 5000 rpms.

rpm pressure
2500 2.9
3000 7.2
3500 8.1
4000 9.6
4500 10.8
5000 11.8
5500 11.0
6000 10.0
6500 9.4
7000 7.4
7500 7.2

Here are the results: 263hp and 246ft-lb torque
I also go to track and my best time is 12.98 at 109.8mph

Going to be putting a t04b hybrid turbo on and see what I can do with it. Hope to run low 12s with street tires
