Another tiny little project today: Protecting the elbows from blowing off under intake pops...

Oh, that reminds me. I have doubts that the MAP sensor was damaged because of the hoses popping off. Pressure relief. (IMG:style_emoticons/default/wink.gif)

I agree, I don't think it is damaged. But besides the elbows blowing off, where is the pressure relief?

No, I meant the elbows blowing off. (IMG:style_emoticons/default/ph34r.gif)


It was a design feature...

Here's a shot of mine....tight fit rubber on barb fittings--I do get the backfire, but not blown any of these off.....smaller diameter than yours...maybe 1/8".

Well the nylon ties are working. Since I made the mixture richer throughout all the 'usable' rpm set-points it has run better. In fact I suspect I am a bit too rich.

One thing I would suggest to SDS would be to write there manual with a tuning sequence. They really don't give you a 'do-this-first-then-do-this' approach in the manual. (IMG:style_emoticons/default/wacko.gif)

Need to find spacers for these front wheels though... Maybe 3/4"?

Aren't the 944 spacers 21mm? I bought a set for $25.

Nice. Yeah, the 8.5 thing simply plays out. I experimented with an inside 9 and it rubbed inside. The inside 8.5 would pull a little off the flare and just clear inside (as your pictures show).

I have another full set ready to send his way I guess. I'll keep the 7's and 8's I have and use those for street tires. Then, as the 911 develops I'll probably move those over there and send those off for 8.5" treatment as well. Seems like the magic number. Actually, I'll have to check the offset on the 911. It might like a set of 8.5's as well. (IMG:style_emoticons/default/wink.gif)

I'm glad that picture worked for you. I was just about to take another with a ruler for a reference...

Harvey is doing a full polish on a set of 7X16 for the street. His wife Susan is hand painting the crests so it will be full-blown sexy!

Actually Eric, Harvey said he can add an inch to the fronts too. I suspect he puts together some kind of offset that brings it out so it is perfect both inside and outside. That guy has forgotten more 914 tricks than I will ever know. Got to be different than just an 8X16 or he would have just told me to source some and he would RSR them.

Chasing down gremlins. I found my idle was high and getting higher so I quit driving it a bit ago. I had a ton of things to do with the 240Z anyway and it was good to work on that for a bit as I am down to just a few things for that to be complete.

What I found was that my entire throttle body tower on the passenger side was wobbling. Well, duh! (IMG:style_emoticons/default/blink.gif) There's the leak!

I tightened up the nuts that hold the manifold to the head and no bueno... I guess that means the seal to the head has been compromised.

So off it must come... Boo (IMG:style_emoticons/default/sad.gif)

Paper gaskets around the phenolic spacer were blown away and tattered!

So does that mean the large displacement Raby engines creates such a high volumetric flow that gaskets cannot withstand it?

Inquiring minds wanna know..

So for today's fun, I did what you might call an educated butt dyno tune. In general butt dyno tuning is inaccurate and can even be dangerous to the engine as you have no data and you can easily go in the wrong direction.

But I have EGT, CHT, and A:F ratio to look at if I want. That's not what I did though. The SDS EM4-F that I control the engine with has a data log feature that records the average A:F ratio in each RPM range that you spent time in during the last running engine session. So, I took a ride... Three actually.

I knew I was running rich as my gauge reads in the 11:1 to 13:1 range everywhere. Given that the car is dual use, street and track/autocross I want to target a 13:1 range with unleaded premium fuel. I am much closer to that now. The engine is clearly happier and I also discovered that I needed to lean out the ACCPUMP feature at both low and high RPM. I also increased the sensitivity and the result is a better throttle response and less fuel gargling on tip in...

A productive day and a ride in the 914! (IMG:style_emoticons/default/driving.gif)

They do if your manifold fasteners back off. (IMG:style_emoticons/default/blink.gif)
