TB Bypass Complete...WOW

Holy crapola!! I never thought this simple mod would od this. The car is much more "froggy" than ever before. It justaround and has plenty of power throuhgout the revband. I dunno if it is because of the 5speed or what but Ill tell ya what, I am not dissapointed at all.

What exactly did you do?

Was your testing on a cold engine? Can you define "froggy"?

Well th TB bypass, bypasses coolant flow around the TB to keep it cooler in summer weather. Origonally designed to keep the TB plates from freezing in cold weather it acts as a damper in the summer by keeping the throttle bodies warm which in turn warms up the air moving into the engine. Not something you want if you are looking for a good air/fuel mix.

To complete the bypass, you simply need a 3/8" ID hight temp hose about 8-12"long and two hose barbs. Simply run the barb from the original, that is now disconnected, to the new peice and then run the new peice to the other original line on the other side of the TB. It bypasses the TB but does not obstruct the flow.

I did not use the valves....yet, I need to pick up the right ones. There will be 3 valves Two on the hoses routed to the TB and one on the Bypass hose that is there now. In summer the two on the TB will be closed and the one on the bypass opened. In the winter, the two on the TB will be opened and the bypass hose closed. A very simple setup will work well for a guy like me.

Froggy- To tend to jump or being quick to react. I mean to say that it has much more spunk and it will get up and go from low RPMs and remains more powerful thoughout the revband. Much like the engine were cold. I have no #'s from a dyno but I have noticed quite an improvement in throttle response at the car's capabilities to grunt down low in the rpms. The engine was at full running tempurature for at least 20 mins so it was running as hot as I will usually get it this time of year(don't drive very far anymore).

Hope this helps...you can also search a post made by Iggdawg that has a compelte writup and he has pics in his locker.

i did a few threads about this too. it worked great for me! like tom said much more throttle response. why did you need the extra piece of hose tom? i just got 1 3/8 barbed fitting and two hose clamps and connected the two lines together. ALL SVX OWNERS SHOULD DO THIS MOD!

Tom,
are you going to have room for all of these valves?

Did you put in the valve that you mentioned or just the "bypass" for now?

If you did the valve, care to share the details? Pics? Or do I have to come to Atco next week to see it in person?
