well over the past few week i thought i would give the home brew tb mod a try.

here is the extra tb i bought


i can't believe how clean it was..lol

next i cut the air horns/fins off



then i went down the my buddys and he offered to take it to the machine shop that he works at and bore it out for me



put backed together



i put on the truck, at first it didn't to do much but take off was alot easier... after the computer relearned a little i had a better take off with less and better throttle response..... but then the $hit the fan..... now i have a problem in 2nd gear so i went back to the old tb and i helped a little but the problem is still here but not as bad,, going to try to fix the trans problem before i put it back on, i may start a new thread about the trans if can't fix it..

and now with the old tb back on i can really tell difference

 

So how much meat did you ended taking out... did your buddy ever told you #'s ?

Nice job!

 

How did you take out the shaft out?

 

Make sure you installed the TV cable linkage correctly if you removed it from the linkage bracket on the passenger side. That'll screw with shifting.

 

Yeah get HBO is awesome !

Did you mean TB ? because last time I checked was BODY not VALVE

 

burn,,,,um, the stock butterfly plate are 50mm so thats what the bore is now, hope that answer your ? plus mm are so small and i need to get a better scale

purlp just take out the bolts and then the plates out and gave it shaft a great big old pull

aim thanks i just took the 3 bolts out of the side and front of the tb, do you think i messed sum thing up? how do you adjust the tv cable, i read about it once but it seems i lost the link for it... thanks

 

Im betting you should post how 2nd gear acts to determine if it is a Tv cable adjustment. Like if its shifting early / late vs. something else. I've taken the three bolts out of the stock tb before and swapped with a fastman. The difference I saw delayed shifts and no power difference since i stay below 2000rpm 95% of the time. Back to the point when I put my stock tb back on it seemed to bring it back to the way it was with normal shifts. So to answer your question about taking the three bolts out, mine hasn't changed the few times I have taken it off to clean the tb, swap the tb, etc... so your prb good. You may have noticed the latter change I said. If thats the case it may just need that adjustment like aim was talking about.

I believe this ought to do the trick for you

thanks pcfixer.

going to try my best, my trans problem only happens when shifting at 2000rpms or less with the poor man tb it would do it all the time, so no to what i does, so form take off 1st gear it will shift into 2nd it 1600rpms then like shift into second again almost like its double shifting this all happens with in a sec on it shifting into 2nd gear the frist time.... so out of 1st gear at 1600(now in2nd) drop down to 1500(we are in 2nd) then jumps back up to 1600 then back to 1500 like it shifting twice..... also the shifts are hard both times

now with the stock one put back on it harder to get it to shift werid, but when it does the shifts are all so hard...

hope this makes cents

 

yes, he meant TV....stands for throttle valve, which hooks up to the TB

 

ya, how much did you overbore? and where did you get the new throttle plates?
