From coolant to cabin temperatures, Vipers are notoriously hot due to having one of the largest engines ever stuffed inside a sportscar. To combat this problem we turn to the thermal insulation experts at HeatShield Products to keep the heat in the exhaust system to lower the temperature inside the cabin and side sills. Hopefully we will prevent our side sills from discoloring and burning our legs when getting in and out of the car without proper clothing and ingress/egress technique.
We've heard that a good set of harnesses can make a difference in lap times, but who wants to go through the ordeal of figuring out where to anchor them and cutting up a car's interior to install them, only to lose the use of the back seats? We test out Schroth's solution with their Quick-Fit Harness system.
There aren’t many more usable vehicles than a Subaru Outback (Scooby Vapewagon). Mild off-roading to your next rock climbing trip? Easy-peasy. Need to take your Australian Cattle Dogs to the vegan dog park? Donezo. Hauling your butch friend Karen and all her camping gear to Beaver Island for a weekend under the stars? Legally, only Subarus are allowed to perform that task. Yet with all these wonderful positives, there’s one annoying issue that nearly makes all these points moot, over time Outbacks can develop terrible rear bump steer (totes gnar dorifto).
Today we get some preliminary testing of the Precision CEA 6870 Gen2 turbo both on the dyno as well as on the tarmac! If you like dyno charts and speedo videos, check this out.
There aren't a lot of off the shelf parts available for a Nissan Juke. In part 2 of this series Lars Wolfe fabricates or adapts many parts and updates the shifting pattern to get Opy further race ready.
Industry Press Release
New and improved! Improved Racing's front-sump LS oil cooler adapter has been completely redesigned with several improvements:
- Now fits both front and rear sump applications! Perfect or rear sump applications that require bottom exit lines.
- New single-piece design with custom edge-bonded Viton rubber gasket is more reliable and less prone to leaking.
- Now lighter and more compact.
In Part 3 of our SAE saga, we finally got our beast running and driving, then promptly threw the diff out like bad Taco Bell. We then jammed to get the chassis welded back together in time for a powdercoating appointment while we took our final exams. With the chassis at the paint shop, we pretended to be students long enough to actually graduate. We then hopped into my trusty old CRV and headed down to see what we got. If you’ve been reading our first three parts, you’ll remember this was an ambitious redesign, with a split chassis, heavily revised suspension, and large weight saving goals. We also had a greatly expanded budget and needed to have a car that was not only fast, but looked good too, hence the powdercoating.
I have been looking for a good single exit exhaust option since I bought the BRZ. I have always liked the single exit look vs dual. Once it was decided that that Project Autocross Subaru BRZ was going to upgrade to a brand name catback exhaust vs my homebrewed special, the search began.
Fuel Starvation is almost always an issue when a high performance car is driven on the track, especially on production cars modified for racing. Factory type fuel pickups are woefully inadequate for a car with modified suspension and sticky tires when driven on the track. Just about all of us have been victims of a sudden loss of power due to fuel starvation when cornering hard. A lot of us have had close calls because of this.
We are going to go out on a limb and make a lot of fanboi's angry. They will call BS and burn us in effigy. However we are still gonna express our opinions which were developed over the years in the school of hard knocks and talk about real issues we have seen when racing and developing many of our industries' favorite and even legendary engines. Now don't get us wrong, these engines can be turned into successful racing platforms when some major engineering and big dollars are applied but a lot of it is beyond the easy to figure out, easy buy and bolt on stage that most street tuners dream about.
When building a race car, the only way to get true brake proportioning is to install twin master cylinders and a balance bar. If you are not familiar with this sort of setup, we're talking about having a master cylinder for the front brakes with a separate master cylinder for the rear brakes. The brake pedal activates both master cylinders at once through a threaded rod or balance bar. As the balance bar is turned, the brake pedal's fulcrum point moves right or left which gives the brake pedal more leverage on the front or rear master cylinder thus adjusting the proportioning.
Our Project IS-F is still around, it has been quietly and reliably racking up the miles doing daily driving duties in and around Orange County. Our car is driven at about 70% street driving and 30% highway driving. One thing we have noticed is that the car has a healthy appetite for tires even though the car is used mostly for family transportation duty. For instance, the factory Michelin Pilot Sports were gone after only 11,000 miles.
When talking with Steve about his car you can sense the passion he has for his STi but also for amateur motorsport. Our discussions went on and on as we chatted about the car, friends we have met at the track, the challenges of building a car that performs how you want it to, and the joy of volunteering and seeing newcomers get inspired by track events. The heart of this story, however, is this 2004 STi which, when you get right down to it, has had almost every component and body panel modified in the pursuit of performance. And boy has it worked!
The newest middleweight sport bike from Ducati gained a few more cubic centimeters putting it awfully close to standard liter bike sizing. Of course, the bigger sibling Panigale 1299 has grown up to 1285cc. However, the 959 might just be the better buy with its upsized engine compared to the previous generation 899 and its price of $15k is right smack in the grouping of price on all the liter bikes on the market.
