New Carbon Bodywork for shop C6 Z06: Project Rampage!

We have finished our shop move and are back to posting tech filled forum build threads! This update covers our in-house build of a C6 Corvette chassis that we call #ProjectRampage. The end of the posts might better explain why we chose that name.

After spending months chasing down fender and nose options for the C6 widebody chassis we show testing of what exists in the marketplace, tried on some cheap fenders (that didn’t fit), show some wider-than-widebody options, and cover the pros and cons of the OEM Z06 / ZR1 / GS fenders as well.

Throughout this update we show how we took our C6Z – missing most of the bodywork – and turned it onto a fully formed chassis with all OEM panels, then explain where it was headed for new carbon bodywork to be formed. If you have a C6 Corvette or ever plan to build a race car from one of these, you might pick up some body panel tips. Thanks for reading!

More 2018 Mustang Brake Upgrades, Tech, and Racing Action!

We have written another 3-part forum post chronicling the testing, updates, and Time Trial events we continue to do in our shop 2018 Mustang GT.

After another step up in pad compounds, Amy and Terry both competed in the ’18 GT at an SCCA Club Trials competition event at Eagles Canyon Raceway, above. Braking endurance wasn’t any better, and at this brake intensive track the brakes were cooked after one hard lap. But with some careful rationing of the brakes Terry was able to eek out one quick lap at the end of the day to win the Street Touring 2 class.

During this same >forum thread update we jump back in time four years and show stock S550 lap times driven by the same driver in a 2015 Mustang GT with the optional 15″ PP brakes. Since the 15″ brakes were pretty reliable then, even on stock pads, we stepped up to this set of rotors/calipers on our 2018 GT – which we bought with the base 14″ brakes.

Following the ECR event we show the upgrade to the “Performance Pack” front brakes with 15″ rotors and 6 piston calipers, as well as new tow hooks and some other tweaks. We also built a prototype brake cooling package for this 15″ setup, which will go into production later this year. We missed one critical issue on this upgrade that hurt us at our next series of events. Read more about this car in our S550 forum development thread, starting here. Thanks!

S550 Build Thread Update: Mods, Testing, & Tech!

We have a lot of things to share in this massive 4-part entry to our S550 Development / 2018 Mustang GT build thread this time. You might want to get a snack, then settle in for a good read.

In this latest update we show the installation steps for the Whiteline coilovers and swaybars added to our shop 2018 Mustang, with dozens of pictures and even a handful of Tech Tip videos along the way.

There is a lot of technical info about the 19×11″ wheel and 305mm tire upgrade we performed. Sure was a big step up from the factory 235mm all seasons – we basically added a 5th tire!

We then do a Race Summary show our Track Test # 2 (at a NASA Time Trial race weekend), where we found a huge ten second drop in lap times from the stock laps run a week earlier. The data logged video is dissected and compared to 12 other late model street and race cars we have driven at the same test track with the same driver. Where the 2018 GT slots into that list in stock and modified form is pretty amazing.

There is also a frank discussion about the unusual brakes found on the 2015-up Mustangs Ecoboost and base model GT. Some real weirdness uncovered, and some unsolvable problems – but we have a plan. You can start reading about it all here.

Thanks for reading!

Vorshlag 2018 Mustang GT – Two Track Tests

The Vorshlag crew has been busy and in its first two weeks of ownership our 2018 Mustang GT test mule has been to two track tests and an autocross. We talk about the first two track tests in this forum thread.

All of our testing is done at MotorSport Ranch Cresson (MSRC) on their 1.7 CCW course. The stock baseline times were hindered by wheel and tire limits, plus the stock brakes.

The latest test showed a huge drop in lap times after we did some suspension, wheel/tire, and brake pad changes. Check out the details and both in-car the videos here.

Vorshlag Buys 2018 Mustang GT – New Parts Coming!

Exciting news to share for this racing season here at Vorshlag: we waited until the S550 got -REALLY- good and bought the revised 2018 GT about two weeks ago! Lots of plans for new parts to make, lots of existing S550 products to test, and many racing shenanigans in the future! Read more in this 2-part forum post.

This is “Big Red’s Dirty Little Sister”, and its got the “base everything”. We explain why we bought the lowliest GT, why the 2018 is special, and what we have in mind in our S550 development thread. The 460 hp direct inj3ected 5.0L is pretty damned nice.

In this first series of posts we cover the best parts of the S550 and get into some serious bench racing. Enjoy!

Dry vs Hybrid Carbon, Seibon Trunk Install, EVO X update, and 86 Updates

We have updates to FOUR different threads on the Vorshlag form to show this time. The first two have to do with carbon fiber parts.

This post talks about the differences between motorsports dry carbon fiber components vs “hybrid” carbon/fiberglass parts. Then this post shows what it takes to install a Seibon hybrid carbon fiber trunk onto an E92 M3.

Next up we have a two part update on our shop Scion FR-S (Agent 86) showing two track tests (# 3 and # 4) we performed to verify lap time drops on the Whiteline Max-Q coilovers and swaybars. The weather was less than ideal but we found another second in lap time from test # 3. You can read those starting here.

Lastly we have updated our EVO X project build thread to cover the last event we did in that car – 2009 SCCA Solo Nationals! Better late than never. This event write-up is a bit overdue but we are reviving this thread to cover other EVO X work we have in the shop now.

This EVO X is getting a full cage and wheel to wheel prep at our shop, which we will show in this same thread in the coming weeks. Thanks for reading!

CARTEK Motorsport Electronics Remote Battery Kill Kits at Vorshlag

After using their products on race car builds Vorshlag has become a stocking dealer for several CARTEK Motorsport Electronics products. CARTEK Battery Isolator Kits meet FIA specs, have no moving parts (solid state design), and bring remote battery kill into the 21st century.

These solid state battery isolators allow for remote triggering of engine/battery kill via buttons in multiple locations, and remove the “arcing and sparking” of old mechanical or solenoid style kill switches. This “no arcing” feature could be crucial if you are shutting down the electrics because of a fuel leak.

The CARTEK GT kit (shown above) kills the engine by taking in a fixed 12v input and sending a 12v output that would power your Ignition or ECU. When the negative side of the battery has been disconnected it will also cut the 12v output powering your Ignition or ECU – shutting down the engine. The GT kit is designed for cars with Standard (OEM) ECU’s or Historic Race cars.

The CARTEK XR unit does not have a power input or power output. Instead it sends a signal which is wired up to either a Power Distribution Module or Motorsport ECU that has an ignition switch signal input. The ECU or Power Distribution Module will then shut down when it see’s this signal – which then kills the engine. This new XR unit also features a 0.5 sec time delay between transmitting the engine kill signal and disconnecting the battery allowing ECUs time to perform a shutdown sequence before electrical power is lost.

CARTEK builds these components in the UK and has a long history of quality in Motorsports electronics. We stock the GT kits (shown installed above on a Toyota 86) here at Vorshlag, and have the best price of any U.S. distributor. You can see the CARTEK battery isolator kits at this page.

BMW E46 M3 CSL V8 Monster & E36 RHD LS V8 Kit Progress

Two different V8 swap build thread updates to share this time. First up is the massive 3-part forum build thread update for the E46 M3 CSL V8 monster we are calling #ChainsawMassacre! You can start reading the detailed updates here.

There is a lot to show in this round, covering 3 months of work: two on-board fire systems, headers were finished, the 8.8″ diff built and installed (see below), fuel injectors, rails and lines installed, oil lines were build, chassis was wired, coolant reservoir built and plumbed, battery kill added, ignition coils and plug wires, fuel cell installed, driveshaft built, interior panels, and brake inlets were made.

After you read and catch up on that customer build above, check out the update on our Alpha development project for the Right Hand Drive BMW E36 LS swap kit! This one was started late last year and is about to wrap up.

In this round we show the prototype 1-7/8″ long tube headers, which are completed and off being replicated for CNC bent, production units.

Once these are back and we can confirm fit we will kick off a production run of all of our Stage 0″ components for the RHD E36 crowd: headers, motor mounts, transmission mount, steering shaft, driveshaft + the bonus swap parts a 3-channel ABS relocation kit, brake lines, and hydraulic TOB kit. We will update you when that happens! Thanks for reading.

86 Project Update, new Whiteline Swaybars and Coilovers

Fans of the 86 chassis know that Vorshlag has worked with shock makers, swaybar suppliers, wheel makes and of course our spherical top mounts since the dawn of this chassis. Our FRS/BRZ/86 development thread (started in 2012!) has some new shiny bits we developed or installed in 2017 using our FR-S test car. You can read more about these updates starting here.

Some of what we did was to help get our test car closer to V8 power, but we also had suspension work we need to tackle. We show some additional camber plate testing we did with the OEM springs before we picked a coilover for this car.

The new Whiteline MAX G coilovers were installed in December and made a huge improvement in handling but minimal effect on ride quality. We talk about our upcoming track test for this set of shocks also.

We installed adjustable Whiteline swaybars at both ends at the same time, then explain how to install these correctly. We needed these big bars in the car to develop our V8 swap headers around.

A prototype for a rear battery relocation kit for the 86 chassis was built for this car – also getting us one step closer to the LS swap on our shop FR-S.

Lastly we cover the long tube header development – which we are doing with a new primary size for our 86 LS Swap set. Again, you can read all about it starting here. Thanks for reading!

Vorshlag’s 2017 PRI Review!

The Performance Racing Industry show is an annual trade show in December at the Indy Convention Center, and it is for Motorsport professionals only – but Vorshlag is giving you the back stage pass with 300 pictures and videos in our PRI 2017 gallery! This was our tenth time to attend PRI and we saw plenty of cool new tech coming out in 2018!

We posted pictures and videos to Facebook during the show from various booths, but have even more content that we are sharing now. The focus for our coverage was new technology and products relevant to our customers – road course and autocross racers. We will cover a few highlights here.

We stopped in at the MCS booth multiple times – bidding Lex Carson farewell in his retirement – and also talked to the folks at Bilstein, Ohlins, and AST. Long story short – there are more performance monotube shock offerings coming in 2018 than we have ever seen before.

Powerbrake had a lot of new car fitments and new rotor and caliper sizes for 2018, plus a few surprises that we are working with them on that will be announced in the Spring. Check out this video showing some of the technology in their Motorsport 6 piston X6EL caliper.

2018 is the year that sequential transmission/transaxle options seem to be at an all time high. We took pictures of lots of options from PPG, Weddle, Mendeola, Albins, EMCO, Sedev, and more. Two Vorshlag builds in 2018 will be built with sequentials – stay tuned to our infamous “forum build threads” to see which ones!

Carbon fiber is not something we make at Vorshlag, but it is something we use on a lot of builds and for wings. We had great discussions with both AJ Hartman and the folks from Anderson Composites. We have many projects that will use dry carbon parts from both of these companies in 2018.

James Clay of Lifeline safety equipment taught us about their new “Novec” fire suppression systems that do not harm electronics. Check out the video we shot in their booth using a functional iPad dunked in Novec fluid here. We use Lifeline fire suppression systems exclusively at Vorshlag – and their steering wheel quick connects as well.

The AiM booth had many new digital displays (MXG units are going into several Vorshlag builds for 2018) and lap timers on display. We love the AiM SOLO predictive lap timer, and the brand new SOLO2 units add an RPM signal input, color back lighting, vastly more memory, and twin lines of programmable color LEDs for shift lights or alarms. We show the new SOLO2’s features in this video.

We took pictures of dozens of remarkable cars at the PRI show, but one of the most thrilling to watch on track is the Paul’s Automotive turbocharged V8 S550 Mustang. This car has a Quaife sequential, big tires, lots of power (tunable to 650-900 hp), and major downforce. Jason and Terry of Vorshlag point out some of their aero tricks in this video walk around.

2017 saw a lot of wheel company mergers and acquisitions – with Weld buying Forgestar, then Momo buying Weld and its subsidiaries (plus several others), there was a new mega-sized wheel company that emerged. We’ve worked with Forgestar for over six years and have already started to work with Weld and CCW. We had a rep explain some of the features of this fully CNC machined, forged monoblock CCW TS12 wheel in this video – which you will see on a Vorshlag shop car in 2018!

Its no secret – Vorshlag loves to put big V8 engines into darn near everything. So we pay attention to new developments for various V8 engines – like this Holley Hi-Ram intake for the Ford 351 Windsor (which is going on a Vorshlag employee’s car in 2018). There was also a FAST tunable Tunnel Ram, new runner lengths for the LS7 FAST LSXR, and many more – check our 2017 PRI gallery to see some of the crazy intake options added for 2018.

There were some booths we stopped at just to see the cars on display – like this 1969 Camaro above, the original Big Red Camaro! It was fun talking with the crew chief about their race at Pikes Peak in 2017. We also saw one of Mark Donohue’s V8 LOLAs, a Gulf livery Porsche 917, the Callaway Corvette C7 GT3 race car, and many many more – see them in the gallery.

Australian engine management company EMtron has a line of ECUs with full Motorsport feature sets, all major capabilities enabled without pricey “unlocks”. Now they have a US based employee for tech support, who we have known and trusted for years. Look for one of these EMtron systems on a Vorshlag race car build in 2018 – controlling different power levels per gear, traction control, active aero, and more.

Don’t forget – you can see our entire PRI 2017 gallery here, and most pictures have captions to explain what you are looking at. Thanks for reading!
