Any possability of slower turbo spool as a result of less velocity due to the larger diameter?

 

Zippy, the headers only deliver the air. A bigger/smoother - less rstrictive header does so with less pressure drop. The choke down point on the turbo stays the same, so the air entering will reach the same velocity, actually a little higher because more high pressure air is there from a less restrictive header.

Have I explained this well? (I'm not sure)

 

Great report Ken. Looking forward to your impressions on the dyno.

 

Ken,

I just love spending your money! Looks great tell
us what the Dyno reports.

 

Ron and I are scheduled for 1:30pm today at AWE Tuning. I have my fingers crossed.

 

Do you have a way to video your speedo when you go through the gears from a roll to 130 mph or start out in third and go to 130? We've been doing this on another forum instead of dyno tests and have been seeing 60 to 130 times comfortably under 8 seconds. The Ruf Yellow Bird broke 7 seconds and a highly modded 930 broke 6 seconds.

For reference, a CGT is about 7.4 seconds.

 

So, you want us to time 60 to 130 in third gear?

 

Ken, great post, great pictures.

Super nice welding on the headers. Cant wait to see the dyno results.

The headers have been made in 1-5/8" and 1-3/4" tube.

 

Ken,

You ought to consider wrapping or ceramic coating (better yet both) your headers. With the higher grade stainless steel being used and the extra thickness, corrosion really isn't a concern. You will notice the extra torque.

 

man...



looking at pics like this. is sparking my inner horsepower demon.. i reallyhtought that i will be happy with just a software upgrade, but now im beginning to think of turbo upgrades and i/c upgrades... yeesh u guys are a bad influence...

Joe,

The disease starts slowly but then spreads rapidly. Get out
now while you can!

 

i know buddy ! but im sorry it seems as if it is toolate for you, your in this thing deep...


save yourselves people save yourselves...

lol

j/k

if i had the funds to do all of this i would have done it in a heart beat...

 

That would be interesting. Check this out with my Turbo R, 91 octane:

Turbo R 60 to 130

That's about the same as a CGT.

 

so...where are the dyno results?? Post them.
