Hello, I can't find any where what the power rpm rating is for the 289 torqer intake, the one where the carb sides a little sideways I would thank it be 2500rpm to 6500rpm. Does anyone know? thanks Jim
Actually, the runner sizing helps it perform from around 1500-1800 rpm up to 5500-6000 without any porting. Beyond 6000 rpm it needs porting. Power curve drops drastically after 5500 rpm.
Yeah, mine had no issues with low end torque, and it outpowered my Performer RPM up top... The power may have dropped off after 5500 rpm in comparison to something like the Vic Jr, however, it was nowhere near the drop I saw with the RPM intake. I spun mine up to between 6500-7000 rpm. I imagine a Victor would have done better there, but I would have lost that good bottom end for street driving. Dave IMO, this is the best street/strip intake for an SBF.
With mine heavily ported, am I loosing the bottom end and gaining top end, or what? Even though my cam is maxing out at 5500 or so. I cannot compare "before/after" because I bought it off ebay already ported. It beats the CRAP out of the Performer I had, hands down, nodoutaboutit, etc. :bananaman I will never go back to a dualplane, and I will always port out whatever I buy. Thanks to Ratio and igo and whoever else recommended that I find one
sssshhhhh. be quiet. most of the ford guys think the world begins & ends with the words rpm & air gap. you'll raise the prices on ebay for torker 289's. want it to go over 6000, just do mild porting & matching, & put on an open spacer (2" if it'll clear). they're fun up close to 7000 rpm. maybe 66-6800. not quite a vic jr, but good street/strip.
I had read where some extensive porting and flow testing was done on some T289s to find the optimum porting for it. They said it gained mucho flow by just port matching the ports (at the head) and porting the roof of the plenum to just inside the top of the port. The first part is self explan... The second, they blended the roof of the plenum into the roof of each port. The other thing I remember very well is they lost flow by doing anything low in the plenum or ports. Even blending... So... DON'T PORT THE BOTTOM OF THE PLENUM! Dave
Hmm, I run a weiand accelerator that has not been ported at all. Wonder if it would benefit from at least port matching to the edelbrock heads. Hard to tell on the flow, the cam is good for 7500 but I am getting spark scatter or something at around 6200. Think I should port the manifold?
i seem to recall that the xcelerator is similar to the torker 289. i would try an open spacer before doing much grinding. just some port matching & blending at the top of the plenum & ports. go slow.
Do you have the new style Xcelerator or the older one? The old version had a severely necked down plenum area below the carb mounting pad.
Intake Porting for Power – Car Craft November 2000 article by Steve Dulcich. The pics of the Edelbrock Torquer 289 intake are worth their weight in gold. http://www.jason.fletcher.net/tech/ccnov2000/ccnov2000.htm
ok... i have a performer.... what intake should i get... i also have a 2 inch spacer.... a 3" x 14" KN filter.... and the 600 edelbrock carb.... cam is .477 / .484 lift ( i know it needs to be bigger) so what intake should i get for use with a .512 cam i want to get...and stock heads for now
i usually lean toward the 289 torker. can usually find them on ebay for a song. dont get one thats got much porting done to it. its just fine stock for stock heads. if you get big heads later, then get out the grinder.
Have I got news for you!!! I had one that I reworked the plenum area on and it was an animal. Can you do any port work?
