I did the same to mine, although I didn't weld anything. I just cut off about a inch, then machined off the other areas to match the OEM piece. Throws are shorter, but do require a bit more effort. I did this mod for aesthetics and not a performance reason. Plus, my OEM one was a little too...
I looked for one a while back, and couldn't find anything. I did read somewhere that a Ford pickup truck's a-pillar was fairly similar in shape. I got one from summit and put some heat to it in order to molded to our A-pillar.
I don't have a good picture, but you can see it well molded...
The Arrow Racing is fully assembled just like you see it in the picture. There is no vacuum source, but takes simple tools and 5 minutes to add one on this throttle body.
X-metal stopped selling throttle bodies a few years ago. I borrowed one for this comparison. I later purchased one from Arrow Racing since no other company was making one. Arrow racing info here: http://www.arrowracingengines.com/2011viperdragpakparts.html
I haven't seen too many threads of people who have done back to back dyno runs to quantify gains. On my heads/cam car, I swapped from OEM to Arrow Racing single blade and gained +18whp/+7wtq. No adverse driving at low rpm and no sticking. Not certain how on how different it would be on a...
Great numbers Dan. Its interesting to see the capacity of what I can assume is the stock fuel system. Was it tuned with SCT, modified OEM computer, or are guys using some standalone system?
Nope. The car does buck a little at low speed. I think that an aluminium flywheel would make a bit more difficult to drive on low rpm. But besides the heads/cam/exhaust, pretty much everything else about the powertrain is stock. I haven't touched the clutch, transmission, injectors, or rear end.
Yes, still have OEM shortblock. There are SC Vipers at about 700whp that have survived for 20k miles, and SCs utilize an any additional 30-40hp to spin. My 640whp probably doesn't impose any more more strain than a 600whp SC Viper. I have had zero engine issues. I do have an A/F gauge and...
I did a back-to-back dyno run with my Arrow throttle body on my heads/cam car. Its a single blade design similar to x-metal, but mine was slightly larger. Gains were about 18whp/8wtq at redline.
See my thread here...
You can purchase American Racing Headers with a the "j-pipe" fit can to the stock exhaust, with or without cats. I ran mine with headers, no cats, and stock exhaust. Had a nice rumble and surprisingly no raw fuel smell. It has been proven my many that catback system yield virtually no power...
I was the buyer who backed out. I thought the tires were 305/30-18s not 19s. I had some pictures sent to me. The tires look great, but won't work on my 18s obviously. Sorry for troubles and thanks for the quick reimbursement on payment.
