So tax return season is upon us and I want to finally get a new bigger blower. My ultimate goal is 750-800 rwhp without dipping into the engine internals. I'm stuck between the gen 3 2.9 Whipple and the gen 3 vmp. I really want the Whipple based on looks and displacement but the new vmp blower...

I was just looking through the seller market place and seen a couple of for sale posts for 20 Alcoa wheels. My mouth nearly hit the floor after seeing the prices. My car came with the original 20 Alcoa wheels when I bought it a few years ago. I kinda knew the wheels were expensive but good golly...

I'm having issues with a mail order tune I just received from a well known reputable tuner. My current setup on my 07 GT500 is a 123 jlt intake, off road x pipe, fresh NGK TR6 plugs gapped at .028" (required according to tuner), and FRPP mono blade throttle body. I originally got a free custom...

I have a 2.6 metco upper for my stock blower and planning on purchasing a 15% OD lower. I don't yet have a aux idler and still running stock pulley system. What size belt will I need for the 2.6 upper and 15% lower? Will I need a adjustable aux idler? Can I run the stock size belt? Sent from my...

I've been on the search for a replacement alternator and it looks like the 4.0 v6 uses the same style alternator or at least the case looks the same. Anyone know if the v6 unit will work? Sent from my PURE XL using the svtperformance.com mobile app

I have a 2.6 metco pulley that I plan to install. I know that a auxiliary idler will give me better belt wrap than just using a 90mm idler. I've seen a few that are adjustable but most are fixed. My question is it better to stick with the fixed one's or get the adjustable one's for even more...

I have a 07 gt500 currently on 20" Shelby alcoa wheels running 285/35/20 tires. I'm thinking of getting a set of drag radials for limited street strip duty. I have a spare set of 18x9 wheels that I can use. Question is will 305/40 fit a 9" rim or do I have to settle with a 275 tire from Nitto/MT...

Found out my stock pump is on the way out. Currently running the stock HE and killer chiller added to loop. Should I replace with another stock Bosh pump or go with the high flow 13-14 German pump? Will the 13-14 be too much flow? On a side note, I read that the 13-14 pump is similar to the...

I'm getting tired of my 07 TPM bands breaking causing my sensors to be loose inside setting a fault message. My question is are the new bolt on sensors compatible with the older cars? Sent from my PURE XL using the svtperformance.com mobile app

Looking at getting a set of lowering springs mainly the steeda convertible set. But i've been in lowered cars and the excessive bouncing would drive me crazy as a daily. But the off road truck stance stock is really bothering me at this point. Wondering how much bounce over stock do you get from...

I'm stuck between choosing either one for my daily driven GT500. On one hand the VMP is a less complicated big dual fanned tripple pass heat exchanger and could keep my IAT2 temps just below 140* in hot Texas city driving conditions but there is little info on its actual performance in hot...

Is it possible to make 700rwhp with the stock blower, cams, and manifolds on a 07 GT500?
