Anyone have an idea on the size of our throttle bodies?

doing a little research for a project.

Thanx

From the echo forums.

Here are the measurements 2.010in air box side 1.810in intake runner side. so this is a ~19 percent difference in Area.

Post the results of what ever you are doing.

By using the program I have our little 1.5L motors will benefit the most from a TB with a cfm rating of 180.6343, sounds technical doesn't it? Giving us 110% of what the motor can use.

With that I figured a TB with a bore of 46mm will give us an hp increase while keeping the flow at optimum for torque, that is if our TBs are smaller than that you listed. If that is a stock TB, if it isn't stock it will be at maximum to keep the flow right for hp and torque.

If my calculations work out we could, on paper, get an extra 15hp out of our N/A motors.Just doing the paper work and research before putting out the money for the work ( actually doing most myself).
Did the same for a little Neon and it smoked most cars I ran it against.Got a little over 50hp increase using stock parts from other DC cars.( before I went all out with it)

Does it sound like a worthwhile project?

do it... this is done on a few other cars also ....

go to it Dr.Frankenstein keep us posted...

That is a pic of a stock throttle body, I found on a echo forum.


HIJACK,

RaiderBeast a FREE MASON???? There was a show just on History channel tonight about the Masons and Free Mason, the Washington DC layout and such. Interesting, I heard of it before but this helped put everything i heard together. HIJACK over.

 

[RAIDERBEAST]

Yea, I'm a Free Mason, I try to do alot of research into history, I've seen alot about the DC layout too. I got in to it through charity type events. its always a good time chillin w/ the Masons.

response to hijack out...

Sounds worthwhile to me - If we can get a Larger TB to swap out for easy HP Gains I'm all for it........Did it on VW back in the day and it worked well and was very easy....but then agian Neuspeed had done all the hard work and research...........

Frog - sounds like you have a plan - let us all know what you fins out....

On smaller displacement cars, like our own, a BBTB is perfect. Your calcs sound about right. If you want to do a test run and bore out one, let me know. I'll buy one and send it to you and we'll give it a try.

I don't have the machinery to do the that sort of tolerance here.

Im sorry i didn't understand for a minute there....im a cnc machinist myself and any production machine shop can most likely do it for a fee but your only going to take out .026 off the intake side right? If so I will talk to my Design/Lathe Department head tommorow and ask him if it can be done in the mahcines we have....i will use mine if it can and i could let you know if it works? if thats cool with you guys but i think it shouldnt be a problem...the hardest part will be getting it not to crush in the lathe jaws lol
