Before thoroughly enjoying the purchase of a used performance car, it’s important for the enthusiast to go through some routine maintenance items. We prepare our 1997 Viper to be driven by changing the oil, coolant, spark plugs, wires, and go through a few miscellaneous items. We then install an aftermarket temperature gauge to monitor how hot the V10 operates and to test the accuracy of the factory gauge.

After ensuring we could stop our newly acquired fun-machine in a previous installment of Project BMW E39 M5, it was now time to let some ponies loose! Our goal; produce more power while maintaining the “quite refined” feel of our performance sedan. It’s no secret the S62 power plant in the BMW E39 M5 was extremely muffled and restricted from the factory. With a price tag rivaling a large down payment on a house, those who could afford a new E39 M5 back in the day were more interested in impressing their power lunch buddies with the M badge rather than with the rumbling performance notes the S62 could belt out. So in the name of sales numbers BMW, like any other manufacturer, put a muzzle on the ol’ girl leaving the performance enthusiast longing for more. But seriously though, what’s the point of having a 400hp engine if you can’t hear and enjoy it?!
We last left you with the chassis in progress and weeks worth of prep and fab ahead of ourselves to have the car ready to start bolting parts on to it. While this was going on in our shop, we had a whole new engine project being worked on by Steve Schmidt Racing Engines in Indianapolis, IN. The goal of the new engine was to improve reliability, make more power and try some new ideas we had been tinkering around with in our heads.
Supercharging Project Tundra is one of the best things we have ever done to any project vehicle in the MotoIQ fleet. The TRD supercharger has proven to be totally reliable in thousands of miles from towing up hill in blazing heat to driving all over the place. It has also proven to be economical as our normal driving gas mileage has not changed at all. If anything the large amounts of power have had only one negative effect on the truck, no traction. To help deal with this we obtained the only limited slip diff on the market for late model Tundra's, the Auburn Gear HP Limited Slip Differential.
Following up on fantastic fabrication of the Project FR-S’s initial aero modifications from the splitter, rear diffuser and rear wing installation there was a desire to enhance the aerodynamic efficiency of the front splitter and rear diffuser by attempting to reduce underbody drag, which most noticeably will be felt on high-speed tracks.
You know that perfect dreamworld where you’re dating a super model and Patrick Dempsey asks you how you make your hair look so cool? It doesn’t exist. In our heads, we should all be driving <insert sports car du jour> and making each and every highway on-ramp a text book example of a four-wheel drift. But that’s not how the ball bounces all the time with life and we need to roll with it.
Hi! For those that don’t know me, I drive the Professional Awesome Evo from time to time. That being said, I am no engineer, I don’t weld, I don’t fabricate, but when it comes to pushing the broom around the shop and holding things while the guys tack important bits of metal in place, I’m a champ. This should be kept in mind when reading this article. I may not be a complete dip sh!t, but I don’t know everything there is to know on this topic. Please don’t hesitate to comment and add to this conversation, let me know where I’m right and where I should get to studying!
We've reached our power goal. Take a peak at how we did it, and be prepared for a smorgasbord of dyno graphs not only from Project Supra, but from other Supras and racecars tuned at Modified by KC as well!
One of the markings of a better shock company is if the company can service their product by offering rebuilding and revalving if the the customer needs it for their usage. We recently visited Tein Suspension since they are rebuilding and revalving the shocks on our Project Supra.
Our SEMA Scion Tuner Challenge car's progress is coming along nicely. With all of our other mods coming together we now will focus on getting serious power out of our FA20 engine with an HKS supercharger. With power comes heat and we will be relying on a CSF racing radiator to take care of our cooling needs.
