Re: S100 Cam tracking/target problems in DTASwin

Thank you for responding. I am not sure I understand completely what you wrote about Idle Control. The manual does explain how using 3 wire ICV will change how you wire up the VANOS, but this is relatively easy, and not an issue. We are not struggling with the wire harness, the issue seems to be in ...

Re: DTA Bracket

*** removed photos and text, it was an accident, sorry for WOB ** Very clean Jon, But there is a small part of me that is surprised you didn't tuck this into some space where it was completely stealth given the overall INCREDIBLE execution of your car, both interior and engine bay.... I'd have to r...

Re: Battery reading

The only thing DTA calls for between battery and its power lead is the main relay and 40 amp fuse. I don't think the fuse is capable of changing the voltage you've got to the DTA. Try switching that relay, or, for a very short time without running the engine, bypass it for the sake of testing the vo...

Re: Parasitic reduction: Pro/Con

as i see it, if you take 300w from an engine then you loose 300w from output! volts, amps, BHP are all derived from watts! your hp on the dyno may well go up, but you will loose else where, toque for example! i dont see how changing the speed of bearings can make them any more efficient. but either...

Re: Parasitic reduction: Pro/Con

if your using more dwell time on the coils when the battery voltage is low, because of the slow running alternator, surely your using more power and thus more drag from the alternator.Drew The beauty of this concern is that it doesn't matter for a track car. Remember, we choose a pulley set up that...

Re: Parasitic reduction: Pro/Con

Dwell table. Activating that feature is how the topic of pulley use for parasitic reduction came up. Thanks for the (intrinsically obvious?) reminder that if we reduce parasitic losses, it should not be at the expense of reliability. It is a valid point, and in fact, the reason the conversation bega...

Re: Parasitic reduction: Pro/Con

My issue is simply down to going to quite extensive measures only to yield maybe 3-4bhp under certain circumstances. I just dont feel it is worth the effort, unless all other avenues of power release have already been exhausted Swapping pulleys and activating an existing feature are extensive measu...

Re: Parasitic reduction: Pro/Con

10 years ago in a hypothetical forum..... Steve: I want to use a DTA to turbocharge my engine in a reliable fashion. Alex: Don't do it, it could be unreliable. Steve: But I think I could make more power. Alex: You could make more power. Steve: So you are a convert? Alex: No, it might not be reliable...

Re: Parasitic reduction: Pro/Con

I'm certainly not a convert. It's obvious various things have drive loads, friction, whatever.....Not a chance. I certainly wouldnt want a system that had massive voltage fluctuations, nor would any professional race team See next note.... On a serious note, I appreciate the heads up that going to ...

Re: Parasitic reduction: Pro/Con

By clutched alternator pulley, I mean the modern ones where it's a sprag/ratchet/whatever you want to call it where it applies drive only in one direction. Like a bicycle crank is best description. Not sure if it would offer any benefit. Well then: Thanks for suggesting something you're not sure wo...
