hmm, thats shitty. I havent had a good look at the exhaust since i got it. I noticed a large improvement. Maybe i will take it to a different guy and ask him to put it up and look for what he thinks may be restricting it and tell him that i will pay him to fix whatever it is.

similar experience

he has 18* at redline.
|
oh, oops

nice job wess the peeps at automotion are definatley cool. They dont run corrected numbers most of the time unless you ask them to. Next time you go back try the 0-60 and 1/4 mile option cyndie i believe her name was says it is a very consistant indicator on what you could run with out spinning etc.
|
yeah, cyndie or however you spell her name. That was her. It was a great experience and i definitely will go back.

if i log a 3rd gear pull utilizing my ebc solenoid vs making the same psi with my wategate.
I make 11psi with my wastegate, i run 12psi with my ebc. I make 12psi at 3750RPM when i use my EBC. I make 11psi at 4900RPM with an open wastegate line. |
wow, so mbc is about middle ground?
|
yeah, a MBC is much improved. the reason is being able to keep the wastegate closed while you make your target boost level. But even a mbc has to start opening as the preload of the spring gets overwhelmed, this cracks open the wategate, and you loose spooling power as the exhaust fails to pass over the turbine.
|
yeah, im running an mbc right now. I can only imagine the shitty spool if i was running wastegate pressures.
|
so brain, what does your spark map look like? I would like to see if i can get it to spool a bit quicker.

Driving Impressions???
I know you are not totally happy with your dyno sheet but what are your driving impressions of your current set and tune? Taking the dyno sheet out of the picture, is this tune/setup seem like something you could live with easily? Sorry for all the questions............:)
|
if you want to see your maximum spool potential...
set your boost spark/fuel cut at your max boost and remove your WG line* *AT YOUR OWN DAMN RISK!:yippee: |
lol, i guess that would work but no.

Okay, i got to thinking, would a slipping clutch cause my dyno chart to look like this? I have noticed my clutch slipping lately. I raced an srt4 from a dig and i had to just let out the clutch slip was so bad. I'm going to call the guy that sold me the clutch and see what he can do to help me out.
(all races described in this post were performed on a track, street racing is illegal and dangerous.) |

So i am thinking that it is a little clutch slip action. I am going to swap the clutch and try to make it to the dyno again.
