Contour Enthusiasts Group Archives Forums Modifications Duratec Performance How Hard would it be to instal a SVT T/B

Huh, on a 95 at least, SVT TB is good for 12hp at 3750 rpms...and I think that is with the stock uim...

Nough said.

Humm sorry buddy its more like 1-2Hp not 12. :rolleyes:

I have a spare (unmodified) SVT t.body with TIPS for say $85 including shipping. PM me if interested.

I'm w/Marco on this one. It's WAY more than 1-2 hp. Easy mod to do, instructions are here: http://www.contour.org/mods/mods.cgi?s=howto&display=svttb
You do know that the main page of contour.org has LOTS of info on it right?
Call Bill Jenkins to get the parts. He knows exactly what you are going to need in addition to the TB. It works better if you already have an intake on the car..sounds cool too! HTH

You know there is a site that has the dyno on this info and Hp gain right, here take a look for yourself. A SE with just a KKM adds a peak gain of 6.1hp. then when you add a SVT TB it goes to 7.5 gain. so you do the math and tell me what you come up with. Heres the site with Info on it

Actually, you both could be correct. With a near stock Duratec like the example with the KKM only, I expect gains are minimal. But as you start opening up exhaust, headers, SVT intake manifolds, etc. the smaller t.body may become a real bottleneck so if it is changed after all these mods apparent gains may be substantial.

but still, the bottle neck is the size of the port opening in the manifold. I mean, you may get a couple HP by opening the path to it, but it still has to go through that hard opening, unless you opened it up with a grinder or something, which, now that I'm thinking about it, wouldn't be TOO hard to do.... just open up the gasket as well. (sorry about the run-on). In all honesty you might gain the extra 1-2 HP by just grinding out those mad bumps in the port and saving the $85 you would've spent on the T/B for something else. I think I have a picture from the October Meet where we did it on my UIM, I'll try and find it and post it later

Kevin, check the whole graph not just the peak gains...

Note that the 12.5 hp quoted was NOT at peak power...But I did deduct the normal gains from the KKM (not exactly right, but gives a better idea of the tb only gains). I still think the results are very impressive...

Actually, just buy the SVT TB gasket! You'll want a new gasket anyway.

I-Dom-In-8 - have you done this mod yet? No? Well then listen to someone who has. It makes a BIG difference in how the car drives. More HP and an earlier opening throttle. I know that the manifold is not as large as the TB (hence the reason I added the SVT manifold later) BUT the stock TB is smaller than the hole in the stock manifold. Don't forget about the area that the butterfly takes up...
Unfortunatly I did not dyno this mod seperatly from other mods I did, but on the butt dyno the TB and the SVT upper manifold were the two best mods yet...
