Hi I thought I would share with you the results I got on a 1984 928s 310 hp with lh jetronic injection, the only mod was the headers the car probably would produce more power with the rising rate fuel reg. at this stage though that has not been fitted. These headers are a prototype and will be improved on and a complete exhaust developed. The power increased approx 13% I hope you find the results interesting. All the best.

 

Greg,

Any chance you can post the raw numbers? Your image doesn't seem to be comming down.

Hej Greg,
also miss the picture supposed to be there.
Is there also work on the heads included with headers?

All the best/Peter <img src="graemlins/jumper.gif" border="0" alt="[jumper]" />

 

I figure it would be helpful for people on the forum to see some dyno results, so they can compare the numbers with their own cars. I am posting my dyno run from 1999, with a stock 83 Euro 928s. It now has headers and exhaust and stuff, so when I get a chance, I will dyno it again. But for now, this is a good baseline for an 83 CIS euro...



Ignore the first run. I did it in Drive, but the car took too long to spool up. The other runs are in D2 and D1. They are pretty much identical. 222 hp at the wheels, and 237 of tq...
