Here’s a car you don’t see around too much anymore. The owner of this Dodge Stealth R/T has been working on this project for the last few years. One out of the many modifications he made was to switch from the original twin turbo setup to a single big turbo.
To go along with the larger single turbo, he wanted a 4-inch custom turbo-back exhaust. After some strategic planning, we were able to fabricate and fit a full turbo-back 4 inch exhaust under the car, without it hanging too low, or being too close to the drive shaft. This exhaust is one of a kind, and certainly a nice showpiece. It was constructed so all the joints are v-band connections. The cat was installed with v-bands as well, so that our customer may easily remove the cat and install the test pipe we fabricated for him when he goes to the track.
The owner still has some things left on his sheet of modifications to wrap up, and we can’t wait to see the car when it is 100% done!

Here are a few shots of a quick mod we do. In order for the COBB downpipes to mate up to the factory Subaru exhaust they have a neckdown where the downpipe and midpipe meet. Even when you upgrade to a larger cat-back exhaust, the neckdown is still a choking point for the exhaust. By removing the neckdown you remove the choking point, allowing you to reap the full benefits of your aftermarket exhaust setup. In addition to removing the neckdown, when we do this modification we replace the warp and leak prone 2-bolt style flanges with v-band flanges. The V-Bands allow the connection to be more easily serviced, and they hold up better in performance applications, as they are less prone to warping and exhaust leaks.

When selecting a wastegate spring, one of the most important things to determine is the LEAST amount of boost you want to run. The reason for this is because a turbocharger cannot run less boost than the pressure rating of the wastegate spring. If you want to run more boost than the pressure rating of the wastegate spring, you can accomplish that with the use of a boost controller.
So how does all this translate into the real world? Well, if you have a setup where getting traction is difficult, you would want to switch to a wastegate spring with a lower pressure rating. The lower spring pressure rating will allow for lower boost levels in gears where traction is a problem, and with the use of a boost controller, you can then run higher boost pressures in the gears where traction is better thus improving the drivability of your vehicle.
Depending on the turbo and exhaust system design, a wastegate spring can sometimes make up to three times more boost than what the spring is rated for with the aid of a good conventional electronic boost controller. For example, if a boost controller is installed that can apply pressure to the top port of a wastegate, an 8psi spring can make 24psi or more, although we typically do not recommend running more than 2x’s the wastegate springs rating as this keeps the demand on the boost control device low.

This car features a custom Verocious Motorsports turbo kit that we put together. The kit was pulled together using the following components:
Verocious Rotated Mount Uppipe
Verocious Downpipe to Magnaflow cat back exhaust
Verocious 3.5” intake
Raw1 Track Series Block with Stock Heads and Cams
TurboXS Top Mount Intercooler
Twin Walboro In-tank Pumps
DeatschWerks 1100cc injectors
FP HTA GT35r Turbo with .82 Tial Stainless Exhaust Housing
Custom Mounted Defi Guages
The car is an animal on the street. With this turbo kit we bumped the stock output from 249 whp and 254 ft. lbs to 380 whp and 365 ft. lbs. There is also more power to be had with this kit, but the car is currently running stock heads and cams and those are the limiting factors right now. The owner is already talking about having some head work done as well as putting a FMIC on the car, and we are very curious to see how those modifications will translate into more power when we have the chance to strap this car back down. We’ll keep you posted.

We had a client with a bone stock 2006 WRX come in for a base line. He told us he had something he wanted to try out, and we said great. So he did his mod, not telling us what it was and we put the car back on the dyno a week later. As you can see from the graph, just the extrudehoned intake manifold was worth a peak whp of 16, and peak wheel torque of about 8. But aside from peak numbers, the area under the curve has increased dramatically. Power deltas across the rpm range have increased as much as 20whp and torque at certain points. I think it is safe to say that the ported intake manifold is worth a solid 5-10% increase in power.
Red Run number 2- Bone stock 2006 WRX
Green Run number 2- Same car but with only the extrude honed manifold
Black Run number 8-Same car tuned at 16psi.

This 1994 Integra GSR has a Jackson Racing supercharger, 50/50 water alcohol mix and is using VAFC for tuning. This setup makes the car an absolute blast to drive on the street. Nice flat torque helps to keep things planted.

This is a 2003 Evo VIII with a Greddy 20g turbo kit on a stock engine utilizing a Utec and a 50/50 water alcohol mix. Boost is set roughly at 22psi. Although it looks laggy on the dyno, its not noticeable on the street.

Here’s a pretty cool project that we just completed, a custom Moto GP inspired exhaust for a Honda Ruckus. If your not familiar with the Honda Ruckus it is a bare bones tube frame scooter that comes with a 50cc engine from the factory. Which means it is as easy to modify as your first BMX bike. The customer who owns this one, has changed just about everything and has turned his Ruckus into a laid out custom. In addition to the cosmetic changes this Ruckus features an engine swap and a big bore kit pushing it out to 180cc’s. Perfect for cruising the beaches!

Thanks to everyone who came out for the dyno day last Saturday. We could not have asked for better weather! From all the feedback we have gotten so far it sounds like everyone had a great time. By the end of the day we had raffled off 13 baseline dyno runs that covered a wide spectrum of cars. Off the top of my head the cars that made it on the dyno were: a 350z, an EVO, a few WRX’s and STi’s, I think two DSM’s, a blown Tacoma Pickup, a Tiburon, an S2000, and a GTi. The highest numbers of the day were put down by the 350z, which just managed to crack the 400 mark.

We are hosting a Dyno Day
Saturday April 25th 10am - ???
This is your chance to get some FREE baseline numbers on your car!
The event/meet will be going on all day. Anyone interested in the opportunity to get on the dyno needs to be at our place between 10am and 10:30 am.
All names will be collected and drawn in a raffle format. The first name will be drawn at 10:45am, with the first pulls beginning at 11am.
Food and drinks will be available for those interested.
We will try and get as many vehicles on the dyno as we can during the course of the day. Our facility is equipped with an AWD Chassis Dyno which is also capable of doing FWD and RWD vehicles.
Everyone is welcome!
Our address is:
Verocious Motorsports
818 South Heald St.
Wilmington, DE 19801
