Hugh, That is a debate all in itself. I have had good success with Electromotives ignition system. I'd use it again in a heartbeat. The problem with it simply that you're stuck with it. You have no choice but to use it... and, its not what I would call inexpensive. Wolf, as you mentioned, doesn't come with an ignition system. However it can be either configured or adapted to work with almost anything under the sun, including CDI. For $90, I built this COP ignition system, directly driven by Wolf... . . ... and there are virtually endless alternative options as well.

*Maybe*. My guess is that is a frequency range that the Safeguard is able to ignore. Thats really a qestion for John (J&S). If you find out, please let us know. Here's a bit of trivia... I was talking to Ross Farnham (owner of SDS EFI) a few months ago... not one of his personal turbo vehicles uses a knock sensor. In his eyes, its a crutch... a band-aid for poor tuning. I'm not suggesting I entirely agree with him... but it is valid, to a point.

Nobody has as much crap as BRAAP

Wolf is configurable for a LARGE number of trigger configurations... it has to be to support 'Plug N Play'. I believe the technical answer is yes... However, I wouldn't run it that way. The cam sync. is only there for 'reference'. In other words, the actual timing comes from the crank sensor (when used in this mode, meaning Ref. + Sync.). If the Audi is anything like some Porches and BMW's, tooth erosion causes inconsistencies. It does... and another popular choice is the 36-1.

No... not hiding. It doesn't exist. Not many systems contain that feature. The ones that do, are generally very limited. The problem is most (performance) engines are very noisy and make different noises under different circumstances. Generic knock systems will frequently 'overreact'. The most elegant solution (I have found) is the J&S Safeguard. It interfaces beautifully with Wolf. Its 'smart' in that it listens only at predetermined times, loads, and RPM, so it knows WHICH cylinder is knocking with usable accuracy. It then has the ability to selectively trim the timing on a cylinder per cylinder basis, resulting in a quasi-custom timing map for each cylinder. Coupled with some of the best ignitors money can buy, makes for a sweet set-up. Its virtually an engine management system all on its own.

From what I've seen, the more radical turbo engines (meaning primarily 4 valve, high RPM, high specific output) have been using some overlap. I suspect one of the things you gain is being able to blow out the clearance volume... otherwise, you end up with a chamber full of leftover 'exhuast'.

Since you asked... if you make it easier to understand your writing, more people will help, including me.

Cpt., Its not easy to get the NA EFI to work properly in a turbo application. Obviously, I'm making an assumption that that is your intentions. If you're asking from a mechanical pespective, yes it can be done that way. Depending on who you ask, it may be less than 'ideal', however. A modest motor, using premium fuel and an appropriate intercooler would probably be an overall improvement as the higher compression (relative to a stock ZXT) would reduce lag a bit. The higher ring lands are a step backward, but if the car is used for sprints (as opposed to extended use), I suspect you'd be fine. You'd be wise getting your hands on a 280ZXT EFI system, providing your goal is modest power. If your ultimate or long-term goals include high power levels, I'd recommend an aftermarket EFI system.

Hi Pete, Here are some spec's to chew on... . . If you have any questions feel free to PM me. Agreed. I think this is Wolfs 'specialty'... easy to use and impressive drivability.

That reminds me. I've been meaning to tell you something... I don't like you. :biggrin:

Don't be like that Kat... its probably only 4.5 lbs

...well then, that makes me powerless

Somebody on zcar.com said it wouldn't work

The J30 coils wouldn't be the most elegant solution.... at least in unmodified form. They are 'tall' to reach down into the head. As Braap mentioned, COP with MS is not well documented... better be willing to commit some time. On the nose of the crank.

Unbelievable

MiKelly is right.

I'll sell this manifold and TB for $400... . . Majority of work done by Braap. Accepts stock style injectors. Ready to polish or paint.

As a couple of you mentioned, a dyno sheet doesn't show the whole picture. A 50hp car can be faster than a 100hp car, even at the same weight. The WAY it makes its power is more important than the peak. And, HOW it functions with the rest of the car is equally important. It does however, if taken in the right context, contain useful information. A dyno report shouldn't be completely discounted, just looked at in proper perspective.

The older I get, the more I appreciate the 'old school' way . This topic has been beat to death, I know. The ONLY reason I'm opening my big mouth is becuse the title of this thread is "brutal honesty". I really feel its in how you look at it. Its simply your perspective. Your tools are just 'older' than mine. You might use a vacuum guage, whereas I might take a peek at the MAP sensor readings. The result is similar... just different 'tools'. Not right or wrong, better or worse... just different. In the end, you've got to use what skills you've got, right? By the way, I have no engineering degree and, I'll bet, I'm no smarter than you

Add me to the list. I have not personally used Ztherapy's carbs... but his reputation is hard to beat. I wouldn't hestitate to use Steves carbs. There are a number of choices... with advantages and disadvantages. You'll get a more useful answer if you share your goals with the car. Fill us in?

A float test is in order... drop MS in an appropriate sized and calibrated bucket of water... If it sinks its BAD. I feel your pain... Sorry man

Dang... go absent for a couple days and the world, ok HybridZ, passes you by. Thanks for the link Dtsnlvrs.... thats the vid Braap was refering to.

I used EDIS to drive the pack, with MS running EDIS. Spill the beans... what are you up to?

You've been PM'd

Chewie, Its nice to see someone care about something historic... unfortunatly you can't save the world. There are many other 'kids that need a home'. The right one will come along... patience my young padwan.
