Fueling Matters! – Updating a Camaro ZL1

We received a call from a client regarding an issue with a tune on his newly acquired ZL1 Camaro. The car was already ¬†modified and sent on the way to the original owner with, lets just call it, a ‘rough’ tune. We can only assume this helped the original owner decide to part ways with the vehicle, and eventually brought Dynosty into the equation. We strapped the 4,000 mile car down to the rollers after evaluating the modifications listed on the original shops build sheet:

Pulley combination good for ~12psi, 1″ 7/8 longtube headers to a catback exhaust, cold air intake, aftermarket camshaft/valvetrain.

The thing that struck us; was the lack of any fueling to help keep this combination safe to romp around on the street. Stock ZL1 fuel pumps can see 650-700whp, ideally we like to see them upgraded as they tend to lose some pressure up top, but the stock injectors are another animal. At WOT we watched AFR climb to a scary 13.5:1 and decided to abort the run. How long exactly was the car being driven like this? We were unsure. We were positive that a call to our friends at Injector Dynamics would solve these issues.

In went a set of their proven ID850s and back on the rollers we went. After a few hours of fine tuning drivability and WOT, Hal finished the dyno session at an impressive 673Whp 652Tq. All on boost levels that could easily be increased with a simple pulley change, offering our client room to grow in the future! We love working with these LSX platforms, looking forward to an exciting spring!

530WHP 439TQ Scion FR-S Dyno Tune

This built Toyota 86 (Scion FR-S in USA) is a great example of what the FR-S is capable of. The setup consists of a built 2.0L FA20 engine that houses CP Pistons, Pauter Rods and Dynosty head studs. Airflow is provided by a Garrett GTX3076 on an upgraded Full Blown turbo kit, and escapes through a Motiv Concepts over pipe, front pipe, and Greddy exhaust. The engine is controlled by a Haltech plug&play standalone ems for ignition and port injection control. Direct injection is retained and controlled by tuning through EcuTek. Hal was flown in to handle the dyno tuning portion on-site in Antigua, and ended with a turbo FR-S producing 370WHP Dynojet on pump gas, and 530WHP on VP race gas.

Congratulations to the hard-working team in Antigua on impressive dyno results, and thank you for your hospitality. Quite an impressive tuner car scene on the island, and beautiful place to visit. Once the bugs get worked out and sticky tires are installed, we expect to see this high performance FR-S fly down the track!

Video of the turbo FR-S dyno pull is below the pictures.

LS1 Powered Nissan 240SX S13 Drift Car Tune

It was great having Jonathan in with his LS1 powered S13 Nissan 240SX drift car. The LS1 swap included some upgrades including Trick Flow heads, cam, headers and FAST intake manifold. We used HPTuners to recalibrate the stock computer on the dyno, with goals of maximizing performance and reliability. Gains of 10+hp were made over the preexisting tune all while making the LS1 safer to drift. Keep an eye out for this car as an up-and-coming performer.

350Z GTM Twin Turbo Install and Tune

A combination of bright yellow, and stealthy black intercooler makes for a car that catches your eye but is a sleeper at the same time. When this Nissan 350Z came to us from Oklahoma, it was a strong NA setup making 238 horsepower at the wheels on our Dyno Dynamics. A GTM Twin Turbo kit was selected by the customer, and we began installation along with supporting modifications including Dynosty stage 2 fuel feed and return system, Injector Dynamics ID1000 injectors, Haltech Platinum Pro Plugin 350Z ECU, Haltech dual wideband, boost control, and more. The end result was a smooth-driving 350Z with serious performance when you ask for it. On 93 octane fuel, we dyno tuned the 350Z to 433WHP – stopping there due to the limitation of stock motor. Hopefully we will see this car back in for a built motor and see where the GTM Stage 2 Twin Turbo kit maxes out.

LS3 powered Nova On Hot Rod Power Tour

1970 Nova LS3 powered at Dynosty

We had the privilege of tuning this beautifully built 1970 Nova, powered by a Chevrolet LS3 crate engine. Using HP Tuners, we were able to calibrate the fuel and ignition maps on the dyno. Power performance and fuel economy were maximized for cruising and full throttle prior to the car leaving for the 2013 Hot Rod Power Tour. The LS3 cranked out 325 horsepower at the wheels and matching torque, all through an automatic transmission. We received word that the car did great on the tour and managed some low 13’s in street trim.

G35 Uprev Dyno Tune Comparison

Tunerzstore.com stopped by with their 6 speed Infiniti G35 sedan for some dyno testing and an Uprev dyno tune. The G35 is outfitted with intake and exhaust performance modifications, and we began with some baseline tests. The stock ECU tune yielded a consistent 210whp on our Dyno Dynamics and was dangerously lean, with air fuel ratio exceeding 15:1 at some points. Next we tested an out-of-the-box tune using Hypertech tuner. The Hypertech tune consistently produced 213whp and improved the air fuel ratio as seen on the comparison dyno chart below. After that we removed the Hypertech and began custom dyno tuning. First steadystate drivability areas of the map were tuned, improving partial throttle feel and fuel economy. We then tuned the full throttle and power areas of the map, including the fuel, ignition and cam timing maps. The final result was 218whp, with gains of 10+whp over Hypertech in some places and 20+whp over the stock ecu tune in places. Check out the dyno charts below to see why it is so important to get your car dyno tuned.
