300ZX Twin Turbo Dyno Tunes on Haltech Pro Plugin

Recently we completed two Z32 300ZX Twin Turbo dyno tunes. Both were updated from reflashed stock computers to the much superior Haltech Platinum Pro Plug-In standalone engine managements. The Haltech EMS is a complete replacement for the stock computer and plugs directly into the stock harness. The standalone also enables live speed density tuning, so there is no need for maf splitters or waiting to mail tunes in and out. The end result of both was better performance and improved drivability.

The first Z32 300ZX was on stock turbos with upgraded Nismo injectors. The results was an impressive 337whp and almost matching torque.

The next Z32 300ZX came in with upgraded GT28RS twin turbos and yielded 429 horsepower at the wheels!

Boosted Performance 6266 Turbo 350Z Dyno Tune 417WHP

This Nissan 350Z came to us from Nashville TN for a dyno tune after installing a Boosted Performance turbo kit, and left with over 400 horsepower at the wheels. A Precision Turbo billet CEA 6266 turbo was chosen with .81ar exhaust housing, and was installed on the factory headers with a 3″ exhaust system. After installing the kit, the team at Dynosty was contacted to supply a base Haltech ECU calibration in order to drive the vehicle to Louisville for a complete dyno tune. Upon arrival, Hal quickly dialed in the drivability and began working on power tuning. 300+whp was achieved and some minor changes were needed to get the boost controller working. After the adjustments we were able to post up consistent 400+whp numbers, ending at 417WHP max at 9-10psi. This is great power for the stock VQ35DE Nissan 350Z engine with Boosted Performance turbo kit on stock headers. Generally we recommend aftermarket headers due to the stock headers restrictive nature for 400+ territory.

R32 GT-R Tuned on Vipec at Dynosty

We had the honor of dyno tuning one of the cleanest R32 GT-Rs in existence. A Precision 6265 Turbo provides nearly 20psi of boost in order to achieve 440+WHP and 300+TQ on 93octane pump gas. Vipec engine management was chosen to replace the stock computer, along with other supporting modifications. Watch out for this show-ready street car!

Recent Uprev Dyno Tunes

This twin turbo Nissan 350Z was trailered into our Louisville, KY dyno tuning facility from the Chicago, IL area. It features a custom Garrett twin turbo setup and very nice attention to detail. The results were over 500whp on 100 octane fuel limited by injector.

HKS Twin Turbo RB26DETT Powered 240SX

Smooth sounds came from the twin-turbo inline 6 cylinder Nissan on the dyno today. HKS twin turbos fed a built RB26DETT transplanted from an R32 GTR into a Nissan 240SX. With Tomei, Greddy and Apexi parts found throughout the engine bay, power came on smooth and strong. Hal was able to dial in the AEM EMS nicely and took the car from barely-running upon arrival to 450+whp on 93octane pump gas. Looking forward to future updates from this car on the road course.

Stillen Supercharged 2007 Nissan 350Z HR Upgrades

This 2007 Nissan 350Z arrived for a variety of upgrades, and more are already being planned. Stillen’s VQ35HR / VQ37VHR supercharged kit was installed with the Stillen / Uprev reflash, and we strapped it on the Dyno Dynamics to get a baseline. At 7-8psi the Vortech-fed VQ35HR pumped out 329whp (red line on dyno chart).

A smaller pulley was then fitted to the Vortech, but due to Stillen’s design a smaller belt was unavailable (8rib 21inch belt) – so we machined a larger idler pulley which worked perfect to tension the back 8-rib belt. The Stillen / Uprev reflash form of engine management was set aside in favor of a standalone, the Haltech 350Z kit. This was installed on the HR using Dynosty’s VQ35HR Haltech Plug&Play harness. After a dyno tune the 350Z progressed to 400whp (blue line).

For that extra kick, a Nitrous Express dry system was added along with a Haltech CAN IO Box to control it, yielding 431whp (black line).

Stay posted for some winter upgrades including a manual tensioner to prevent front-belt slip, and a built motor as we push this setup even further!

James brought his 350Z in from Chicago needing a few bugs worked out and a tune. We quickly identified and remedied a few problems, such as wideband signal being wired to the wrong input with O2 correction enabled. The car performed well on the dyno, and Hal was able to draw a nice chart on the Dyno Dynamics dynamometer – matching 486WHP and 486TQ.
