We were pleased with our S54 3.2-liter in stock form, and the goal was to bring it up to V8 M3 performance. Was a 12% power improvement and 90-lb fat reduction enough? Find out inside! We test them to speed and in the quarter-mile. We also compare them from 30-100 MPH in third gear to compare low- and mid-range torque for you track guys! And why not--we even throw in a Mustang GT 5.0 in there...
Life would be a lot easier if we'd stayed with the stock headers, but when we tested our VAC headers in Part 3, the increase in power was too much to let go. Since then, we've tried different header-back systems but they either were too loud, droned at low RPM, or didn't fit all too well. Today, however, we think we've found something that works great and doesn't break the bank. Dynos graphs and video clips inside!

“Same level dry performance as a Michelin Pilot Super Sport”. That is a HUGE statement by Continental when the PSS is hands down the segment leading benchmark. Continental is extremely proud of their brand new ExtremeContact™ Sport tire that was just released earlier this month as a replacement for their ExtremeContact™ DW tire. We logged nearly a thousand miles on the new Sport in both the wet and dry, and put it up against the outgoing DW in a back to back test at Palm Beach International Raceway to see if it lives up to Continental’s claims.
Due to the high capabilities of the Viper, a huge strain is put on the factory oiling system on road courses and at the strip. This can cause oil starvation and a spun rod bearing. Using modern rubber can increase this risk, especially for 1996-1999 Gen-2 Vipers which have arguably the worst oil pan of any generation of Viper. To combat this problem, we upgrade to the larger 10-quart oil pan and windage tray from the 2000-2002 Vipers and install RareFab/Roe Racing’s race-proven Oil Pan Baffle Kit.
Packing more than 50whp over stock, our Project E90 M3 took to the track at Palm Beach International Raceway (ROAD COURSE) to see how it stacks up against a 2016 Ford Mustang GT. Both cars have similar power, weight, and are equipped with similarly sized Continental ExtremeContact DW tires. How will our modified 8 year old sport sedan benchmark compare to a modern “pony car” that’s transitioned away from its roots to become a corner carver? Read on to find out.
When you think of a high-performance E46 3 Series BMW, you may automatically think of the ever popular M3. It’s true that the E46 M3 produces great power with its fabled S54 inline six. It also looks amazing with its distinct fender vents and aggressive front fascia. While this 2001 325ci BMW may not be an M3, it will decimate all other cars with an affordable and reliable power plant from an American classic – the GM LS series engine.

We were eager to get into our motor and install the Ford Motorsports parts that would basically enable us to rev to over 8000 rpm reliably and breathe better on top. The parts we accumulated would bring us to a spec about the same as the Ford Motorsports Aluminator performance crate engine and a little bit more than the Drag Racing Cobra Jet NA engine.
When we last left Project Lexus SC300, we had been fabricating panels to secure all of the electronics. Even for something as simple as installing a few electronic components, it takes quite a bit of planning and execution in order to do it correctly. That planning and execution continues in this installment of the rewiring series, where we secure the Autosport Labs Racecapture/Pro2 data logger and construct other block-off panels.
The Yost Autosport BMW M4 endurance race car gets some power and cooling upgrades from GIntani and CSF Racing! Plus, we feed the beast with a massive custom Fuel Safe fuel cell and Aeromotive fuel system components. And more!
