Sean E Yamuni

Colin could we get a side profile shot of her I'd like to be able to admire the Rays and stance of vehicle w the camber specs and agrresive fitment referenced she looks amazing ....something to strive for ...
I feel like my car is close yet so far away
Thanks for your time

Will this do Sean, loading the car onto the dyno this afternoon?

^^^ Looks really nice Colin .. What kind of h.p./torque are you expecting?

NineMeister

I'm definitely feeling a little bit ropey today. Probably the result of inviting my customer to celebrate the finish of his car with a litre bottle of Jim Beam? We stopped celebrating when we lost the ability to communicate.....

NineMeister

Previous experience with this engine specification suggests that 340-350bhp should be in order, but with the revisions to the bottom end we can explore a higher rpm limit than usual so might find more above 6900. Will soon know.

My new word :-)

This was an early picture when Colin was still able to operate the shutter of his camera.

I have a strange felling that I might have switched to Swedish as my ppm past 2.0 Which could have explained the loss of communication (can happen above 2.0 ppm of which I have no re-collection

Seeing the car live is just so much better than the pictures are able to transmit. In the the 9m shop they have a factory 993GT2 CS and I looked at this car and inspected all the welds on the cage. They where no way as good as on the 9m93RSCS and this further fuels my feeling that I have some thins that is really special !!! a 9MRSCS

As some of you Rennlister´s may remember Colin mentioned that he had some tuning going on and he showed me (not all) what they are up to and I was amazed to see that they are above the hp/litre of the 458

I think my car will go back to 9m

A little 'hair of the dog' required?

I assume if you have fitted R888 tyres that the car is not going to run on the road?

I'm looking for a tyre that I can drive to track days with and then on track but which won't wear at a alarming rate. (I use R888 on my 968 but they fit in the back of the car with no problem...not an option for the 993)

How does a 993 feel on the R888 tyre? (I think they do hard and soft from memory)

This has been a good thread.

wonderfull car, amazing toy for big boys like us!

Gratulations to Colin, Marc and his team for another perfect build! It was a pleasure to follow-up the process! Hope another 9m project is already on the way...

one question about the steering wheel:

Who made the airbag cover upholstery work?? I'm deperately looking for a black leather example with blue contrast stitching...

Nice work Colin, really looks great.

Do you have the f and r wheel and tire specs?

Also, post the dyno when she is done.

NineMeister

Patience is a virgin.....

Latest dyno plot attached, 350hp & 429Nm. The engine is what we call a 9m 993 Varioram +3 specification which has rods, 102mm 9m pistons & cylinders, 9m billet heads, 9m Sport cams, 9m Sport valve spring set, ported Varioram intake with 100 cell cats. The air pump system has been partially deleted (not required in Europe) and the 88pin ecu fully remapped. The rev limit has now been raised to 7500rpm.

(Before anyone asks, this set up is fine for European legislation I don't think it would be suitable to pass US engine check standards, hence we are looking at other solution at the moment for the US market.)

Toyo R888 are road legal so that's how the 9mRS will leave our premises on its way back to Europe. Fronts are 235/40 rear are 285/30 on 8.5" & 10" x18" Rays TE37 rims. We had to roll the rear arches to get the 285 tyres to clear.

Thanks Colin...

The power curve is very interesting, very flat from 5750 all the way to redline... I tke it this is a factor of both head flow and cam choice.

Bill Verburg

Very nice!!, What would it take to get it to rev to 8K?

Why no Motec on this one?

NineMeister

The rev limit could be raised higher, but with a close ratio gearset with a maximum of 1300rpm between changes from 2nd through 6th the extra rpm on a falling power graph would reduce the acceleration speed at the expense of significantly higher engine loads, friction and wear. It's just not necessary, the car will be faster where it is.


Limited cost to performance benefits in addition to the problem of accurately mapping the car for radically differing climates and altitude for its use in Europe. A Motec M84 or M600 conversion may find another couple of hp here and there, may also achieve a better response, but to be honest even with the compromise over requiring frequent check light resets due to the lack of SAI it is difficult to justify the expense so we (me and the customer) decided to push the funds towards a better chassis and brakes as we believed there was more to be gained there, especially with one eye trained towards future 9m developments....
