hey i just got my weiand team-g intake manifold in the mail today. im still getting parts for the rest of my engine.

anyways.....

im living in Rexburg, ID where it sometimes gets in the teens below zero in the winter months. i have heard some people complaining about icing up in the throttle body. im wondering if there is a heated TBI to 4bbl adapter out there that would help me cure this

or

if anyone out there has driven a Single plane TBI in the winter and the results they had

thanks

 

i think i read somewhere about a stock GM 454TBI adapter plate that was coolant heated? anyone have a P/N or link?

 

I have seen one, but it won't bolt up to your manifold, a team G has a squarebore flange, the truck adapter has a Qjet flange IIRC, go to the local junkyard and look for suburbans and 3/4+ ton trucks.

 

yeah i read that, but i guess i could make adapt the q-jet to squarebore flange

also what years did they come in?

 

All smallblocks went fuel injection in 1987, I think bigblocks went in 88 or 89, but TBI was optional on earlier models IIRC.

 

I hope you don't plan to run the stock hood with all of those adapters on top of a team G.

 

well its going on a truck that has more clearance than a f-body

but im not sure what clearance issues i will have. ill make it fit one way or another.

 

Just put the stock air cleaner housing on it with the heat stove pipe. It will keep the TB from icing. Atleast it did on my Edelbrock 2912 Victor Jr 2bbl.

 

is there an easy way to convert headers to work with the heat stove?

 

Doesn't the TBI already have coolant heating?

 

only TPI has a heated throttle body, on a tbi motor, the intake is heated which transfers to the TBI

 

I ran a weiand accellerator single plane for 2 seasons(store car 11/20) in wisconsin. BUT it was with Xram plenum so it therefore is doubly bad and not in a good way. I will suggest it will be very cold blooded. I needed to let car idle for maybe 3 minutes and still had drivability issues until 10 min of driving. I think Holley used to sell a coolant supplied adapter plate. Check their site.

 

Hell with my 3704 tbi intake my car I'm still having a bitch of a time tuning AE in this cold weather. I have to let it warm up for like 20 minutes or it runs lean as hell. So I can imagine it;s going to be a bit of a bear to get right

 

do you have the IAT sensor installed? im wondering if this would help cold issues or not.

 

I run an IAT. When cool on coolant <180d it runs off open loop tables coolant based A/F. IAT is helpfull. Once it hits 180 it flips closed loop and IAT helps again but only to a degree. Issue is fuel falling out of atomization if the manifold/TB is cool. I dont think IAT can help in that regard. You would need coolant crossover under manifold which my heads do not provide. Also a heat riser which again I do not have. I think this issue is also present in carbed cars in cold environment.
