Thought?
Hey guys, I dont know much about volume or acceleration of air going into the intake manifold, but I was wondering if anyone would see a loss in power if something like this was fashioned. The intent in mind is quite simply to remove the rediculously long throttle cabling and minimizing binding at the same time. I'd do much more work in developing it of course if it wouldn't effect hp at all. Forgivness if it's a stupid suggestion, I was just thinking yesterday how I could clean up my engine compartment, and this was a thought.

Here's a photo about what I'm thinking. Now, I understand I'll have to find a way to cut the aircraft cables and put a new knob to control the accelerator drum assembily, and a battery relocation may be required to make a go of it, but I think this would remove those unsightly accelerator cables and not make any more clutter than there already is. Thoughts? I dont want to be flamed here, just didnt sleep last night and this popped in there. (thanks vadium for the size)

The only downside I can see right now is slightly worse throttle response.

As for the throttle cable, have you seen this? Worked wonders on my lowport as well.

I see the reason in your link there Ben, but I'd be worried about the significant bend in the tubing binding up right where it enters the engine compartment. Also, what makes you say there would be worse throttle response? I am asking because I dont know how that whole thing works with ambiant volume inside the IM and if that would affect anything or not, I dont see this being any different than say a 45* bend in the intake piping, which isn't uncommon. I hope my illustration made it clear that there would not be any bends in the accellerator cable which is what I wanted to avoid because of the potential for binding and seizing of the cable. Hopefully you know what I mean. This was the best way I could think of to remove that problem while still keeping functionality.

(btw the reason I put this in VVL was because I have a VE engine, wouldn't mind it if the moderators changed it to general sr20 because it applies to all lowport motors.)

I managed to run mine so that it took shallow bends (shallow enough for my tastes) everywhere and was well hidden. I zip tied it where needed and no binding whatsoever. I understand if the hidden cable mod is not for you though.

Only because that's generally what happens when you move the throttle plate further away from the intake valves. That's why ITBs are so popular. Because they increase throttle response by getting the throttle plate as close to the intake valve as possible. I'm not saying it's going to be a big difference or even a noticeable or measurable difference. It will probably be tiny at most.

There is no difference. You're right.

Yah I see what you're trying to do. I just didn't think throttle cable binding was even an issue. I've never heard of anyone having any trouble.

Also the MAF has to be a certain distance away from the TB right? It would probably end up somewhere where the battery would be right now.

Which would take up the space your trying to clear up......but the trottle cable would still be short.

done the hidden cable trick on 2 ve's no problems..

prolly should do the g20ve soo too lol
