Chipwizardry update

[Richard Dawson]

I took my car to Wayne yesterday, and I think like everyone else can only say good things about Wayne and his skills. Apart from anything else i learned alot from Wayne about the art of ecu work, 993s and seting up cars generally. Wayne is utterly methodical and machine friendly and has an impressive set up. The level of airflow and extraction at his workshop is amazing and clearly of particular relevance to an aircooled car!

As soon as he hooked up my car he noted that the varioram was not working and then spent 2 hours finding and fixing an airleak. As an aside it appears someone had connected up some tubing incorrectly when it was last off. I do not wish to defame anyone. My car was at Porsche Bolton to have the wiring recall done when someone last meesed in there.

Anyway that fixed he cured the lumpy idle and popping on the overun with sport cats and after some time produced 297 bhp from 283.

He said usually RS get a bit more than that, but did not see anything overly out of place.

The car is now fundamentally smoother, better in traffic and much quicker!

It had a new engine a few thousand miles ago and so I wonder if it is still tight ?

Anyway in summary money well spent!

Richard, I am slightly confused......Now if we assume a standard RS is 300 bhp, they are rarely much if any above in standard form if you use a din 70020 rolling road.
With the varioram out of action 280 ish horse would be about right, getting the varioram back in the game, should clearly show an improvement from the 280 level.
Are you saying 297 was after varioram and chipwizardry was performed on your car?
I would expected such an improvement from the addition of a healthy varioram alone.
if so, good for Wayne, he appears to be conservative and not flashing about big numbers, if you had said it now had 312-318 bhp post chippery it would have sounded perfectly feasible to me.

fwiw my varioram sprung a leak in the box and cracked the elbow ,power loss IRO 50 bhp..............................Best day Andy Tims ever had at Goodwood in his 3.2 Clubsport i cud nt loose him in a straight line the length of the Lavant !

 

[Richard Dawson]

Sorry if I was unclear, but here goes again.

Before the car had a run Wayne fixed the Varioram then it produced c280bhp on its first run which for the avoidance of doubt included the varioram functioning.

Wayne doing his thing then manged to clean up the idle, cut out the popping overrun smooth out the curve and increase the area under it generally leaving a 297 bhp max figure.

Wayne's view was he can genrally get 10-15 bhp more out of an RS like mine and hence my wonder if it was tight after its rebuild or if there is some other issue to explain why it is a slightly weedy RS!

 

[vic cohen]

perhaps helpful as a ref point my almost 100 000 miler [owned by me from 34k now with Ben Saville at even more !] was 304 bhp ALWAYS and AFAIK still is ..........................never touched engine or ECU

it was rs cs with LOTS of work that pooped its vacuum box !

Have seen Wayne de'smog' standard 993 s and develop mid range dramatically, be sure he knows where hes at ; he has worked hands on with race teams in the past on the mechanical side of things, reckon gives him a really good overall perspective .............

 

[Scott R]

Would like to get in touch with Wayne ref looking at my car, can someone let me have his contact details.

Thanks

Persevere with getting hold of him.

Kind regards

As mentioned 297 post chippery magic, doesn't sound amazing....but then again my understanding is that Tuv & Porsche tolerances for a factory engine were 5%, so, 285>300<315, would be acceptable for a standard 300 bhp car, therefore 297 certainly within range, hard to imagine there is anything too seriously wrong with it, maybe it will loosen up?..How many miles since the rebuild?

 

[Richard Dawson]

The thing feels fine to me and certainly works well; I understand it was only rebuilt a few thousand miles ago.

I am happy as Larry with it as it now drives so much better and has Varioram again!

Kind regards

I had thought that RSs were well known to often be a few short of the quoted 300bhp. I know rolling roads are a bit of a mugs game for measuring bhp, but I've often heard of 270-290 for cars in fine condition. 297 post the session sound quite satisfactory I think

Think these rumours cud be attributed to timimng slipping before it was deemed a good idea to 'peg 'cams ..................or in my case stop fat people slowing the cars down !

Quite true. I've seen 3 that came in at figures like 260, 270 and 280. All well used so probably just an issue of getting a bit worn, but even post rebuilds they weren't over 300

Just goes to show that a well fettled '64RS engine is the superior of the two...just ask Wayne![] Much quicker cars.[] []

 

[Richard Dawson]

I didn't realise that you could work on the ECU of a 964RS to reach 300bhp without any hardware mods such as airflow meter, exhaust etc.....

Still I must admit I was thinking of starting a business of supplying kits to retro engineer a semi-trailing arm, small brake and oil leak mod to bring the 993 RS up to 964RS spec.I believe the mods certainly increase grip, improove handling and lower lap times significantly. The kit wouldn't of course include iron front hubs as these items are just too expensive to manufacture so unfortunately seems the aluminium 993 hub will have to stay. God bump steer is great.

Actually scrap that I best just upgrade to a 964RS...

It's all good![] [][]

See you all at Oulton?

ps: would love a 993 really (as well as).[]

 

[Richard Dawson]

Clearly the joy of owning these things is not about absolute speed as we'd all have Caterhams or something equally insubstantial!

I had a 964 RS in the late 90s (it is currently for sale at GT classics for just a bit more than i sold it...) and loved it too. Given a free rein and bank account I think i'd like a '73, '64 and '93 so that I could ponder which to take out to play in.

To quote Sean Lockyear " given a few drinks you can construct an argument to own a 993 RS and a GT2".....

Wats wrong with that ? The Mrs believed it rs cs /rs and gt2 perfect set honest .......................

Strange that they both seem to be up for sale at the same time!?........Chance to buy the clubbie back to show her she was in fact...right and you should never have sold it after all? []

Always makes me laugh how these lads come on to other forums slagging cars off, they are all great cars...I just hope he enjoys his as much as we do ours. []

 

[ChrisW]

Yes, Wayne's reputation seems to be riding high --- and almost a Yorkshireman ! http://www.porscheclubgbforum.com/micons/m9.gif

But a little strange to think that the 964RS based engine may be a better starting point for tuning than a 993RS lump ?

P.S Is it only me that can't see the smiley ?
