Has anyone made any progress on a TBI spacer for the 1.6L 8v EFI? I remember a thread about it a while ago, but I can't remember who said they were messing around with one... :-/
-
I made a wooden one a while back, but I messed up one edge while sanding.
I had a spare TB & intake sitting around and put it on for a test fit. The corner wasn't sanded perfectly flat so there was a very small gap between the wood and the intake surface at the corner.
But, I did figure that I could go up to 5/8" or maybe even 3/4" spacer and not have to replace the TB to intake bolts, which would be nice since I can't find any longer bolts locally (I haven't checked the Web). Does anyone know if the TB bolts for a auto and a manual are the same? My auto has that heater between the TB and the intake and it's about 1/8" thick.
I also rechecked my air intake tube to hood clearance and I think it'a about 1", maybe 7/8". I don't know how tight that would be with a 3/4" spacer and possible engine roll when revving :-/
I have been thinking of larger tires and maybe a BL one of these days which would make a 1" or 1-1/2" spacer no problem (if I can find the bolts or maybe use threaded rod as studs).
Anyway, I probably won't get back to this until I make the decision on the BL or I just get tired of waiting for myself to make a decision and make another one (a little more carefully this time) ::)

Hey guys would like to know if anyone has done this im thinking of making one too out of alum cause TBI likes heat from what i read.
-
These are available
I can't remember where
I saw it tho :(

Have you TBI guys ever thought about using one of those white plastic cutting boards as a source of material for the spacer? They should be easy to shape and drill. I don't know if they're resistant to gas but could be worth a try since they're cheap.

Haven't thought about that, but I think I'll nab one of those from a local thrift store (if I can find one) and use a gasket for a template. Even my dull drill bits shouldn't have any problems working that stuff. :)
Good call.
BTW, who was it that used a cutting board to make a driveshaft spacer? ??? Or was that over at Pirate?

tbi spacer???

SpinalTap: where'd you get that at?
92Sidekick4x4: Throttle Body spacer

ah, gotcha

Okay, now I also know what it is, but what does it do ???

Yeah, I had thought about the plastic (or whatever that material is) cutting boards.
I was going to take a chip of the spouse's plastic cutting board and sit it in a cup of gas to see if it dissolved or something.
I would think it'd be really easy to work with.

Looks good. What material? Is that more than 1" thick. Have you installed it? If so, what are your impressions?
-
That's the one I saw, it's made of 1"
aluminum plate and annodized red, but
I remember they were kind of expensive

what difference in power did you notice with the TB spacer????And who makes it?
-
I got the spacer off ebay for around $40. The seller's name was Kevin Harris...I'll send him an email to see if he can still get them. I won't be able to tell you what the performance difference is because I am installing it with the new engine.
I have a cold air intake for it as well...so with the Calmini cam, ported/polished head, Calmini header/exhaust and the fresh rebuild I'm hoping to feel a bit of a difference over stock ;)

Did it come with longer TB bolts? I'm thinking there may be 1/2" available on the stock bolts, but probably not much more.
I was not able to find longer bolts at the local hardware stores.
I didn't look for threaded rod. That would be a nice solution I think 'cause it'd be like having studs. But, getting metric bolts/nuts/threaded rod/or anything metric in the states seems to be kind of tough.
-
Yes it came with longer bolts.
-
I just got an email back from Kevin, he is expecting some in 'soon'. So anyone interested keep an eye out for them on ebay. Hopefully he'll send me an update when he gets them so I can let you know.

doesn't a spacer give more horsepower, but less torque, where a shorter intake does the opposite??
-
The length of the intake runner
changes the ram force of the intake
charge, think of it like stopping the
flow of water in a long pipe, and then
stopping the flow in a short one
Shorter I think is better for higher RPM
Horse Power, and longer is better for
lower RPM torque
Wild
-
Yep Wild has it right, it is designed to increase torque.

Theoretically, I'd like to see some one dyno test one on a Track/Kick. I played with manifold lengths on my old race bike. The shorter the manifold the more power I got everywhere. I spent ages making the longer manifold too!
-
There are other factors involved too,
size of intake runners, port and valve
sizes, shape of the port floor and even
the shape of the combustion chamber.
shorter intakes seem to be better on
high RPM engines, the ram affect has
lots to do with the speed of the intake
charge too, a speed of 220-300 feet
per second seems to work well, and
will increase power over a slower speed
intake charge, even at the same RPM and
Cam ect.
Wild
-
Ok well then a shorter intake would be better for the 1.3, since it is a higher rpm motor?
-
Higher RPM being defined as
6000-15000 RPM :o
I don't think the Sammie is ready
for that yet ;)

Hey Wild now that you've mentioned cams, I compared my Calmini to a stock cam last night. The Calmini has less lift but a more asymetric profile. The lead side of the lobe is almost flat, the trail side has a egg like curve to it. The stock cam is almost symetrical but definitely ramps faster on the lead side. Another oddity on the Calmini cam is the distributor end. The large flange is probably 1/4" closer to the front of the cam than it is on the stocker, even though both cams are the same length. We slipped the Calmini into the new head and it has about .035'' clearance to the back of the distributor housing.
I'm sure pumped about getting this engine together :)

can you use a dial gauge and degree disc once its installed and give us some numbers?

The guy that's building the engine is going to do just that...I just have to remember to relay that info here ;)
This is a real learning experience for me, he's letting me get my hands into all of the prep and he's explaining everything that we're doing and why....its kind of funny actually, we have my little 1.6 on one bench, then on another he's building an Olds 455...I'm pretty sure I could stuff the 1.6 block down one of the 455 bores ;D

That is a "good" builder you have then ... that's the kind of service someone who cares about you does ...

Best of all he live just a couple houses away and his shop is there too ;)
