Default TB Bypass help

Can someone post a link to the page that tells how to do this. Pics would be helpful. I know this can be done with parts from my local hardware store but which parts do I need? Please help if you can. What kind of SOTP and actual HP gain can I expect?

If you get a 95 hose you can get rid of the t-fitting on the upper radiator hose.

I will lose some coolant when I do this. Do I have to replace with Dexcool?

I tried to do the TB bypass a little while ago but I had a problem with the hose. When I tried to pull the original hose off the TB it seemed to be fused on. I would have just jerked it hard to get it off but I didnt want to rip it. Any ideas?

Sometimes they get stuck on there pretty good over time. The only way to get it off is to cut it or jerk it. You might want to have some spare tubing on hand just in case, or have another car you can take to a parts store.

As for losing the coolant, if your car has dexcool in it, its only compatible with dexcool and should be topped off with that. I believe it is pre mixed, so you shouldn't add water.

Try twisting the hose off with a pair of plyers. This may damage the hose, but it probably needs to be replaced anyway.

try heating it up, if you've ever had to change a hose on a hot engine you'll notice they come on and off really easy

Dexcool is orange I believe. You will only loose a cup or two of fluid

Just cut it off with a blade. You have plenty of spare when you route the driver side over to the pax side 'pipe'.
