Welcome to RennTech.org Community, Guest
Ive just had a dyno test on my Boxster S, 2000 model, 158 000km, RHD, daily driver.
I have a 'dip' in the graph readings for both power and torque between 5 800 - 6 300 r/min - see attached.
Any thoughts as to what this could be caused by?
No misfires or any other symptoms. Scanner shows no fault codes.
Im satisfied with the results, bar the 'dip', as the flywheel HP is usually about 12% more than is achieved at the wheels.

So for my car , 996 C2 , 2003 with 70 TMiles and M030 suspension .
Im currently in process of purchasing several parts for suspension refresh , so to say .
Whole process came to a corner , left or right , from perspective of refreshing it since rear shock absorbers , i have planned to purchase are not available , anywhere .
At least not for reasonable/decent price
Plan is to refresh my stock M030 shocks , front and rear , where Bilstein B4 is standard which came with car .
Now , i have received front shocks but rear ones are not available and supplier does not know when they will be available .
I could not find them online , also , not a single supplier have them on stock, so only option , order them , pay them and wait for Bilstein to make them and deliver ..
Development of situation is is that my supplier have offered me Bilstein B8 as option , more or less same price as B4 .
Now, guys ,..
As part of refreshment i have bought several additional parts, which are part of suspension and fit B4 setup, for all 4 corners..
hexagon nut M 10
additional spring - bump stop
So to say rubbers and plastics ..
Springs i plan to keep , so no new springs planned ..
Will all those part be usable with B8 shocks , so plug and play .
What will be height difference , is B8 height adjustable or height is same as M030
WIll B8 shocks be delivered with installation manual
I have read recent article , it seams, came in right moment for me 🙂
So positive opinion on Bilstein B8 , which is ok , but im not worried about B8 on German Autobahn , my worry is as i wrote , will this be plug and play considering replacement of current ROW M030
or something needs to be bought specifically beside refreshment parts i have already bought .
Have some experience with wrenching around , front shock mount , Wheel bearing , basic service , sparks, mufflers , ignition Switch , etc ..
But few additional thingies and advises as additional knowledge is always welcomed .
Thank you very much guys ..
Does anyone have or know where I may have the bolt torque specs for a 2008 Cayenne Turbo? I need pretty much the specifications for all the bolts and nuts that would be included in a block replacement. I'm getting the back rebuilt by 928 Motorsports and reinstalling with an experienced friend. However, it's nearly impossible to find the specs for these motors. Additionally, if there's a place where I could find a complete 957 workshop manual, could someone please advise? Thank you.
Pulling the front end on the GT3 to get at a dead horn... found the dust boot on the front strut torn. Has anyone replaced one of these? I had a competition suspension set up from Jae Lee at Mirage in San Diego and don't want to mess it up, but need to replace the boot. Can I just remove the mounting at the top and drop the suspension and replace the boot from the top? ANy help on this is greatly appreciated!
I recently did a suspension overhaul when I replaced my inner CV joints out of necessity. Problem I am having is they cannot align it properly. Because of the lowered suspension and change in geometry the rear toe in is more than it should be. I have ordered a pair of rear control arms from TRS to allow for adjusting toe, hopefully. So now I am looking to replace the Meghan racing tie rods with something that will allow for greater adjustment for proper alignment of the front end. Does anyone have an experience/insight into this type of setup for the street? Can anyone recommend outer tie rods? Will stock factory ones work?
List of what was replaced:
All wheel bearings with *** units repacked with Hi Temp synthetic grease
All 4 struts/shocks with Bilstein B8's along with upper bearings/caps, bump stops, dust boots
All 4 springs with H&R 29779 Lowering springs (Blue)
All 4 lower coffin bars/ball joints with Meyle units
2 rear track arms with units from Vertex auto.
2 rear control arm/ball joint Meyle units.
2 front track arms not sure if Meyle or vertex auto.
2 Inner tie rods
2 outer tie rods with Meghan racing units, adjustable blue color
4 Drop links with Tarrett adjustable units
Eibach 26mm front swaybar along with bushings
factory 19.6 rear swaybar along with bushings
