The shipment of nylon blocks came in yesterday.



The two shorter blocks on top are for a couple of Yaris prototypes for dyno testing. The rest are for another production run of tooter Tacoma spacers. There's a set of aluminum parts in the works right now, as I'm also building another tooter intake manifold.

So there's three projects all going on at the same time.

Sweet. I finally welded my tooter together last week. I'm going to dyno before and after as well. Wont be for another couple weeks once I make the intake and hopefully get a 'rolla tb

That sounds painful.

The very first tooter I.V intake manifold spacer prototype is done...

I suppose a flatter torque curve :) Longer runners give you that whilst shorter runners give you a bit extra horsies.
That's the theory at least. I know there are some cars with variable intake runners.

You can see on this dyno chart exactly what 2 inch longer runners do. This is with the tooter II.VII spacer on my Toyota Tacoma.



Blue line is without the spacer, and the torque peak is 3,150rpm.
Red line is with the spacer, and the torque peak is 2,900 rpm.

Basically it moves the whole curve downward towards lower rpms as well as fattening up the curve a bit.



Tacoma manifold with spacer...




I'm expecting a similar effect on the Yaris when I dyno test it. How much, who knows? And that's what we'll find out.


Greg

I don't mind you asking because the threads get large and I wouldn't expect everyone to read everything. I just answered your question in the last post.

Latest news... the prototype is being engraved with the tooter logo today, and I pick it up tomorrow morning!

So I'll try to get it installed and running on Sunday and I'll give you guys my driving impression. If I can find time off work, I'll get it dynoed this week.

Looks nice, and I estimate the tacoma runs a bit smoother and lazyer with the 2 inch?

Still that is a pretty flat torque curve to start with.
