Project Update to S550 Mustang LS swap – TRIGGER! #LS550

After a 13 month gap in coverage we have caught up the Forum Build Thread with work done on our #LS550 test mule race car we call #Trigger – an LS swapped 2015 Mustang GT. This update covers all work from July through December 2020, then pics up on the the work again when we restarted this project in August 2021. This is a rather large forum update, with 100+ pictures and some video, which you can read here. Warning: you might want to grab a drink and some snacks, and open this on a laptop of PC to see the high resolution pictures, all of which can be clicked and expanded.

In the latest Forum Build Thread update we cover many subjects – the installation of a rolled radiator, Accusump unit, remote oil filter, tow hooks, 4 port steam vent kit, the intake manifold, discuss ignition coils, install a PP1 undertray, build brackets to hold an aux fuse panel and Holley Dominator ECU, sensors, brake lines, driveshaft, and more!

There is a lot of ground to cover on this update – hopefully you will dig further into the Forum post and see the many build pictures, read the what / why / how behind each task, and maybe it motivates you to work on your race car this weekend. Thanks for reading!

468″ LS7 Powered E46 M3 Build Thread Update

This long overdue Forum Build Thread update covers work completed on this wild 686 whp LS7 swapped E46 M3 from early 2018 through June 2019.

In that period we completed a lot of custom fabrication, including the elaborate radiator ducting and hood exhaust, twin filter box hood ducts, massive splitter and rear diffuser construction.

Many construction techniques and design aspects of these aero devices are covered, with over 100 pictures in this update alone.

Dozens of sub-tasks were tackled and completed in this update. A tune was loaded for the HPR built 468″ LS7, then engine was started, and lots of “first fire” testing was completed at the shop. Then it was off to the race track for the first track test.

We learned an awful lot at that test and brought the car back to the shop to fine tune many aspects and finish some of the incomplete bodywork. You can get caught up with that large chunk of work starting here. Thanks for reading!

Updates to E46 Endurance Build

Our shop employee built E46 endurance race car has had a big chunk of work completed in the last few months. We have finished the cage, added window nets, wrapped up the EPAS steering column, painted the interior, and the engine bay is much further along than ever before.

You can read all about the latest progress at the latest entry to the Forum Build Thread, which we have cross-posted to six forums (all linked in the first post).

We like to chronicle all of our builds in detail, for people to see how we do things and to remember later on when we tackle similar work. Thanks for following along on our forum build!

Two Track Tests & First Mods to C6 – Project New Balance

The last four weeks with the narrow body 2006 Corvette C6 have been busy, and this Forum Build Thread update covers every bit of that work. Some maintenance has been done, some seat testing, then the first on track test to get the Baseline Stock best lap on the MSR 1.7 CCW course.

The first laps in stock form were “not fast” but the car still had potential, so we immediately ordered three sets of wheels, better tires, and real track pads. We cover what was purchased and why in the latest Forum Build Thread update.

We then took the C6 back to MSR for a second track test, and with wider Hankook RS-4 tires and better brake pads, lap times dropped 2.5 seconds – getting closer to a stock C6 Z06 lap time. We also tested a new dual 1080P vidcam, logged CAN data, and created in-car video for both track tests. All of this and a LOT more is shown in the latest Forum post. Stay tuned for more next time when MCS coilovers are installed, along with new seats, new tow hooks, and more!

New Vorshlag C6 Build- Project New Balance!

We have 3 shop owned race cars under construction, but a busy customer build schedule and the usual “scope creep” are keeping us from getting any of them to the track – our solution was to buy a running “narrow body” C6 Corvette and start driving it immediately. Our reasoning and goals for this project are detailed in this new Forum Build Thread.

Of course we cannot leave anything bone stock around here, so it will get some simple upgrades like MCS coilovers, wider wheels and 200TW tires, bigger anti-roll bars, some mild brake upgrades, and a better cooling system. While this sounds like a lot, this will stay a 100% street legal car that can be driven to events – like many of our customers tend to build. Stay tuned to this forum thread for the baseline road course laps at MSR and ECR, then parts will be installed and we will chronicle each upgrade’s lap time changes along the way. Read more here.

Massive Forum Update for V8 E46 Endurance Car!

A lot of work was completed on our after-hours, employee built, LS swapped endurance road racing E46 coupe. In this massive 4-part forum build thread update we cover 8 months of work that was done about 3 hours per week, so it gets drawn out a bit.

But being such a drawn out build lets us take the time to document every step of the process, even the experimental items and build procedures we are trying out on this car. We are pushing the limits on some aspects that we might not otherwise attempt on a customer’s car – we show both the successful and the abandoned processes and parts used in the latest forum build thread post.

Lots of systems are wrapping up: the roll cage (above) is about 95% complete, all of the suspension is done, the 5.3L LS V8 and Tremec TKX transmission are in, and the third and hopefully final seat is in place.

We also received the correctly built set 18×11″ wheels, then mounted some 315mm tires, and the fenders have been cut and clearanced for these and flares. There is still a good bit of plumbing and wiring to complete, but we’re going to push to get the car moving in April so we can try to make some races in 2021.

’67 Mustang Track Build Update!

This blog post is just a teaser for a massive, 3-part, Forum Build Thread Update that covers work on this ’67 Mustang from May 2020 thru January 2021.

The forum update cover a ton of work done at Vorshlag in that time: The strut towers were modified and reinforced, initial camber plates built, S197 spindles and brakes installed, steering completed, and the front suspension wrapped up. A power steering pump was modified and installed, a bit of cage work completed, the 18×11″ wheels and 315mm tires were fitted, a fuel cell was ordered and mounted, the entire fuel system was plumbed, and the Holley EFI system was wired.

Long tube headers were fitted to the 427″ LS7 engine, cooling system started, and hood hinges modified. Tremec has since released their TKX, so I can show that now. At the body shop a new hood was installed, the front doors and fenders were fitted, the rear wheels flared, a carbon lower air dam went on, and the whole body was blocked, sanded, adjusted, sanded some more, and primed.

The initial plan of building a simple track rat has grown into a respectable track build with a real paint job. This opens up the opportunities for this car to series where all of those things are important. Want to read a lot more? Start here in the latest forum post. This is also cross-posted to the TrackMustangsOnline forum, the S197forum, and the Lateral-G forum.

8 year Journey – Jamie’s ST3 Mustang

In this latest Forum Build Thread update to our original S197 development thread we focus on 8 years of updates to one car: our customer Jamie Beck’s S197 Mustang. This car started life as a dual purpose street/track car but in 2014 he wanted a safer, dedicated race car build, and we gave him that.

Follow along starting here to watch the transformation to a gutted, caged, and wing race car as it developed from HPDE entry to NASA ST2 and ST3 wheel to wheel race car. Lots of weights are shown, as well as construction pics, the T56 Magnum XL and transmission cooler upgrade, aero changes, classing changes, and rules discussions.

Recently we began repairs to fix issues in a 2018 track incident, and we loved seeing this super clean race car in our shop once again. Now that the car is repaired and all of the expired items (nets, seats, belts) are updated, it will be running in ST3 for part of the NASA Texas 2021 season. Again, you can follow along on the entire 8 year build and update journey recently chronicled here in our S197 development thread. This is also chronicled on the S197forum and Track Mustangs Online.

Shop Truck Silverado SS Conversion

As part of the front sheet metal repairs on our GMT800 generation shop truck (tree fell on it) we have updated to the 2003-05 front and and Silverado SS trim level, on the exterior. We show all of this and more in this 2-part forum post.

Of course it was not as simple as we had hoped, and we ran into some snags with model year changes, parts supplier issues, and even model year changes.

Lots of cutting, grinding, bracket fabrication, some welding, tweaking, and a little hammering got all of this to fit

Once the work was done it was time to load up the truck to take to the painter. They will replace the roof panel do the paint work, then we will dive into the rest of the work we have left. Thanks for tuning in, and you can read the latest forum post update starting here.

Endurance Road Race CTS-V Update!

At long last we have some customer and shop car build progress to show. This time we catch up on the Cadillac CTS-V endurance car “update”, which has snowballed a bit after it arrived at Vorshlag.

In the latest Forum Build Thread 2-part update we cover the rebuild and upgrade to the 5.3L aluminum LS engine – where it turned into a 6.3L race motor built by HorsePower Research. We also show the clutch, pressure plate and flywheel refresh – then show how to measure hydraulic TOB shimming.

One of the big upgrades we are tackling is removing the junk GM ABS unit and installing a complete Mk60 Anti-Lock Braking System. This entails sourcing a custom wiring harness and all of the BMW components, wiring, and lots of plumbing. This car had pretty janky brake lines so most of the hard lines have been replaced.

Lots of other updates are covered – the weight difference between the chopped up OEM front crash beam vs the tubular unit we built, the locked up Delrin bushings being replaced with grease-sable poly versions, and then the three Lexan window installations we completed. All of this and more is shown in great detail in the Forum Build Thread starting here.
