Looks like it should work well, as long as the supercharger does not run out of puff it should make power to around 7300. L/C of 114 sounds good.

Will be a nice tuff street cam.

One question, are you really going to run 93 octane with the supercharger????

Topic: 4zc1 turbo cam?
Replies: 8
Views: 3123

I would suggest something with around 220deg @ .050 and .400ish lift, LSA of 112-114. This should make peak power around 6500 but will fall of soon after, however it is a good match for the turbo and will retain good manners with a slight lump at idle. This cam will be good for around 180-200rwkw re...

In my experience I would not trust most cam shops to provide what you need but perhaps that is just my experience. Coxy's cam will probably be a bit big for your needs, I would guess something around 225@ .050 and .400 lift would work well (coxy's 300 would be advertised but is most likely 240+ at ....

I used to run a diesel diff behind mine when i was making 196rwkw with a HKS 2540R. I found it worked well on the street with that power as it makes first a bit longer and keeps wheelspin down a bit in the first few gears. should be ok with 170atw as long as you make boost by 3000-3500, you will not...

For the tachometer you could use logic gates (a 4 input AND gate) off the negative from each coil. I have seen factory dual coil (waste spark) use this. You could use 3 of these modules to add up all the signals but a 4 input would be neater.

I am also using the Haltech hall effect sensor but mounted on an alloy wheel on the front of the crank pulley (this allowed me to remove the dizzy). 3 magnets, 2 timing signals and a home signal which will fire 2 waste spark coils. As said previously there is so many ways to do it. In my experience ...

To tell you the truth I don't know, they may be good for 9's with some reliability or not any stronger than an MSG. There have been reports of breakages with moderate power levels (can't remember details) but myself and Coxy (redzone) plan to test them in a 10 second drag application. Sadly neither ...

As most things it all comes down to personal preference, the power figure you want is achievable with many different combos. If you plan on getting the car engineered then one of the first steps would be to talk to the engineer and get a list of requirements for your short list of setups this may ef...

Unless you are planning on making over 200rwkw and drag racing then I would stick with the MSG box as it will be plenty strong enough if not driven by an ape. Unless your master is too small then you should not need to modify pivot points and such. As for the Throwout bearing I have talked to a memb...
