There is a strip here as Prd2BCdn pointed out

But
- You blow a day to get 3 runs
- Costs 25.00 to get in but you don't escape for less than 50.00
- It's only about every third weekend they have street runs

There is none out where my nephew is.

Ok guys
     Last night nephew reported in with the results on the 1" spacer.
" Same tests, same bodies, same place etc. 3 sets of 5 runs each"

- Repeated runs with 2" spacer...average 23.0 (flat), I think the young buck is getting the
  hang of this.
- Runs with out spacer...average 23.2
- Runs with 1" spacer... average 23.1

Reports doesn't feel quite as perky but not much different, still a measurable benefit and the 1"apparently clears hood without modification.

Fuel mileage...

Stock (after tune up)..........31mpg commuting
2" spacer............................33mpg commuting
1" spacer............................31mpg commuting

Now these results are not the most accurate
- rookie tester
- manual stop watch
- eye ball start stop
- done a 1000km away from me so I can't supervise

But the averaging should mitigate some of the error...

     They consistantly show an improvement with having a spacer
and the 2" does seem to show a little more improvement.

     Man I wish I had the money for about 20hrs (about 5000.00 Cdn inc set up)on a Super Flow computerized engine dyno....I'd really like rock solid proof of what the actual hp difference is.

     FWIW...Spacer due seem to improve things a little and it's a cheap mod.

     So far spent about 30.00 in aluminum, 4hrs building, 20.00 gaskets, 18.00 freight and I owe my friend on the coast a couple cases of beer for swapping parts around.

A 3" TBI spacer might be the hot item for
allthe guys that have the 3" bodylift  and
want to retain the stock air filter setup.

Also you guys need to have the other end
of the intake runner supported so it won't
break your TBI unit. Ask me how I know

Hey Wild
     Mathmatically the air velocity starts to drop off at 2.68", but thats theroritical.
That's also why I didn't go any taller. But I would bet a 1" spacer at the air inlet
side would get the extra inch for the body lift and help the airflow a titch.
     The only way you would know for sure is to try it. But I don't have access to
anything with that kind of lift and the nephew don't want no holes in his hood.

Zag

Well 2.68" is close enough the rubber air
slinky should connect back together with
the filter housing

     If a guy has got the room I think the 1" air inlet spacer machined like a velocity stack and the aluminum air intake tube opened to match would be a neat improvement and probly worth the effort.
     But to be honest I'm running out of time right now and have some business revenue producing stuff to catch up on...maybe later we can try some of the other stuff with spacers

Zag,
I'm building a spacer within this week.  its never going to get tested or anything like that.  what size do you want me to make it?  there are just too many things about 1in or is that 2in or 2.68?    it could be a foot long if you want, its all going though the hood anyway...

Stu

After seeing your aircleaner pics and that long intake tube I would think the 2"

     The reason for the 2" is there are know results....with that long intake tube I would flare the end inside the airfilter housing (like a bugle) it will help with the airflow, and have the lip of the flare and inch or 2 up from the base.
     That way you've got somewhat of a known with the 2" spacer and some thing to experiment with on the intake tube.

Good luck

Zaggy, Are you thinking about making any of these for sale? If so, how much do you think they would cost? I would definately be interested in a 2" spacer for my Goblin Tracker...

Hi Digger

     I hadn't thought of it....I was just kinda passin on the info. I could but is there really enough guys that would want them?

     To do it inexpensively, cause to be honest I'm out of scrap 2" aluminum plate, you'd need to do them in batches like your coil spacers.

     I guess if enough guys are interested I could price out doing a batch. But I want to get
more feed back from the test subjects to be sure of the results. But yeah if the results are confirmed and enough guys are interested to do a batch I suppose we could.

     So everyone knows, the original 2" spacer is on another test Kick (friend of nephews) and I'm waiting for confirming feed back. I also have one more test subject I would like to have evaluate the installed piece.

How many guys would be interested???

Zag

Like I said before, I'm definately interested and might even want 2 of them. I'll trade you a set of 1" coil spacers for one 2" throttle body spacer... LOL!

But you're going up....

I'm going down..... (there is no double intendra there!!!!!!!!)

Maybe I should throw it on the forum, after I get to evaluate one personally,
to test interest? Whattya think?

Zag

I'd get a 2" spacer ... unless I fab a 1.5" first 

I'd be interested in one.
