ROW 408/430/450 bhp questions..

I'm pretty sure it wasn't either. But Andial did sell the kit for a while, and that's where I got mine. Another benefit of their "special relationship" with PMS, I guess. Andial's was the same as what Gert's now offering. I added an Andial exhaust and left off the twin tail-pipe thing, 'cos I already had big ovals and liked that look better. While it wasn't legally emissions-compliant, it would easily pass a California smog test. I brought the car to the UK about three years ago, and began tracking it. The K24's worked great everywhere except really slow corners (the Goodwood chicane comes to mind). My UK independent is JZMachtech (very good guys), who also happens to be the Manthey UK representative. They were the ones who shipped the ecu across to DE and installed the 5-bar FPR. I think the cost was around GBP 2500. Probably could have been done for less somewhere else. This is an example of incremental modifications. Not the best way to go, long term, but I think a lot of us on here have been down similar routes! Hell, I'm still on that highway.

The 430 hp & 450 hp kits (WLS I & WLS II) were sold through Tequipment (see Tequipment catalog 911 Typ 993 08/2001). The price was EUR 6,400 and EUR 12,180 (plus installation).
The official 0-100 km/h no. for the 430 hp kit was 4.3 sec vs 4.5 for the 408 kit. Top speed was rated as 297 vs. 290. Top speed for the 450 hp kit was rated at 300 km/h. I haven't been able to obtain any official 0-100 no. for the 450 hp kit.

Unless you're using them on the track or for prolonged high speeds when heat soak becomes an issue. Although significantly quicker accelerating my car has a lower Vmax with the UMW stage 2 kit than the Porsche 430 ECU.

Interesting point you raise Phelix, maybe Kevin could elucidate his thoughts on the heat soak under sustained WOT?
Trust all well with you and hope to see you in a few weeks at v-max
Kind Regards

Phelix like I have told you and have written on this forum. You should run a higher octane race fuel, when you take the car on the track or run it under sustained loads (flying mile runs lap after lap) If you don't timing will be pulled as the engine heats up and is prone to detonation.

Have run super unleaded (98 rated) plus Silkolene Pro Boost with good results, and last time out at the RL mini v-max half a tank of BP 102 plus half tank of SUL (as the 102 ran out).
Phelix, if you are coming to v-max will gladly bring some Pro Boost for you to try

As an aside, I asked RS some time ago about higher octane fuels and their effect on perfomance, etc. Gerhard Schmirler said in typical fashion after me asking about BP 102 - Well, I think no difference unless you go for 104 octane plus. Obviously our cars 'need' 98 at least, but does the ecu really 'sense' and maximise the benefit of the loopy juice such as 102? This is getting O/T and might be better as a new thread?
#26
When putting these cars on the track 102 BP and your juice cans that you guys are putting in the tank is slowing the fuel burn > which is reducing detonation.
Gary is correct, the 993 turbo "S" in the US just bumped the timing and a little boost while running the stock K16's..

When I said "a few guys on RL have them" I was referring to "cytefx" (UK) and "Rassel" (Sweden) who both have German spec. cars. Thus RLers on this side of the pond.. Sorry for the confusion Chris.

I'm not a Vmax junkie (like some on this thread ) but it's one measure of the car's performance.

Phelix when I took my stage II 997tt to the track the last summer I started getting some hesitation at WOT on a front straight near 150mph. This was a very dangerous sign to me that the ECU sensed something suboptimal and was pulling timing and boost. I was running 93 (US) octane and refilled the tank with 104. There was an immediate difference and my front straight speed jumped to 160mph. Just as Kevin stated as you are increasing boost/flow in a turbo motor you are reducing the amount of headroom the motor has for suboptimal intake charge and higher octane race fuel is a cheap way of giving the motor more headroom back. Dumping some race fuel into your car for the next Vmax will likely produce a higher terminal velocity than a 430ecu car, unless something else is deficient with the motor.

I experience significant performance gains when using race fuel and since I've had my intercooler cleaned, the performance has been sustainable (i.e. no heat soak) for around 5 laps on the Bahrain GP circuit. Sure, after that, the power is pulled back by the ECU, but after 5 or so laps I'm ready to start my cool-down lap
