dyno result

[rs phil]

got it done while at manthey racing,277 ps @ 6075 rpm,and 337.6 nm torque@ 4915 rpm

mods done are fvd remap two exit cargrapic xost dansk final silencer and decat,k&n filter,and 993 airflow meter

remap and exhaust was originally done in 1995,was pleased with result as graph is very good no dips..and 95000km on engine and their dyno would be very accurate

got cup diff plates and geo done while there,different car now,cant speak highly enough about manthey really are great

whats that in english currency?

 

[Melv]

273 bhp -on the money for a standard RS.

So, with all those mods, we're not impressed!! Must try harder!![]

You sure that wasn't measured in KW?[8|]

 

[rs phil]

yep 273 bhp,and 250 lb torque,i could go to different dyno and probably read 300bhp...

graph had no dips and its still up on standard with 95000km..so i is happy

i have been in 2 964 rs lately with 350 bhp motec etc,dont feel any more powerfull maybe slight more torque...all just numbers[]

has open airbox also,going to change this to standard as i think it draws in too much hot air...what best here some extra holes or none??

Is that Belton Horse Power???[]

Too much hot air will be a prob, espec in this weather -as to whether more holes will work, I don't think so......if it is a concern, a snake/snorkel to a cooler part of the engine bay prob best bet......perhaps refit the original 'snorkel' from the filter box ? -after all, I'm sure Porsche designed that with a reason!!

Thought any 993RS started at 300BHP ...... where are you Clubsport?

 

[vic cohen]

Disguised as Clubsport.............my 100 000 miler 993 rs put out 304 , never touched the engine ......................just found the missing 10% on Baby Blue , wire broken from solenoid to resonance flap [ no varioram]..................now 320 ish pretty ordinary fig for Cup Car ......................

IMO fiddling around with rs like these just tends to make them unreliable for limited returns ...........................have to run Cup Car on standard cans to get on on track days costs a few bhp , but what else can u do ?

[rs phil]

have standard airbox on the way from douglas valley breakers,think you are correct melv porsche would have put holes there if they needed them

cone filter must be worse problem?

 

[Alexander_Drobik]

All very interesting - the standard air box did take the air away from the back of the hot engine and also made it proof against water, dust etc to a large degree. The cone filters, if mapped correctly, will give a few more bhp esp if it is extended away from the back of the engine. I found on mine I got a few bhp more in hot weather by shielding the metal pipe between the cone filter I have and the intake. Also, on cone filters it needs to have the volume to suck air in - the Porsche panel ones do cover a large area even if the hole in the box is somewhat small. I doubt that drilling the standard airbox does anything other then make it louder, just my opinion of course!

In 1992 Roland Kussmaul told me to get rid off that original snorkel - it was designed to match Switzerland regs in terms of noise (Hope I remember that correctly). He said the open air box (frame left to keep the filter in place) is a good solution and will give a few more horse. I also put in the K&N filter element replacing the original one. As it makes the car real loud, it´s hard to tell if all that works, never dynoed it.
Walter Leupold who some of you met in Spa has a great dyno in his shop, had a lot of cars on it and says the K&N filter really works. I never found it necessary to put mine on the dyno.... as Phil says, just numbers.

Hope that helps a little bit,

My airbox is cut like a Battenburg cake with one hole right in front of the inlet trumpet.

Incidentally, the inlet trumpet on my car has gauze across it so I assumed it was run at some point sans filter....tried at Donny a few years ago, the noise was excruciating and it felt down on power!!

Hacki, that sounds quite possible.

I tried to export a LHD 3.8 (X51) engined 993 C2 to myself in Switzerland, and couldn't because the gearbox ratios were different !! All to save noise. It would have been far to expensive to do all the proposed work, so ...

I drove it back, and sold it.

Shame, because it had PSS9 dampers and was a very nicely sorted car.

And sold for £22 !!!

The engine, incidentally, was an original blueprinted 3.8 964 engine ... but without the fancy induction side of a 964RSR.

 

[rs phil]

i noticed that in photos that 964 cup cars had open airbox...o yes the 350 bhp monsters were 9 .......dyno

when i got my car it had about 4- 25mm extra holes towards the back of the airbox

it sounds like v tec at the mo with it open.. i think the last time i had standard one on the car felt better down low and not as keen to rev to 7000rpm as with it open,but on track i found after about three laps of a short circuit i would need to change up earlier as power would tail off after each lap

so maybe porsche ran them differently for different circuits??

I think your car is a matter of trying each way on the dyno... it´s different from the standard Cup car. This Porsche engineer (better?)[] had just developed all that stuff for the 964 Cup car as it was run those days. Maybe -and I think for sure- a highly modified engine reacts differently. So, only trying on the same dyno tells the truth....
