Rb25 Turbo Upgrade, All Dyno Results

[hypergear]

93 model R33 GTST Forgied CP pistons, valve springs and stock every thing else.

800cc injectors

600x300x75mm Front mounted cooler

Xforce 3inch turbo back exhaust

Profect B electric boost controller

Brea bolton manifold.

SS2 prototype (290612) Internally gated. 14psi actuator, internally gated.

4inch intake pipe

Adaptronic Plugin

Greedy EBC

Further evaluation on the SS2. it made 337rwkws on e85 externally gated it made 337rwkws at 18psi peek just touching 20psi. I've also trailed it based on internal gate running boost controller and straight off the actuator.

The solid red and green are from internal gate, Green is internal wastegate pressure:

Boost curve for all runs.

Also same car specifications, trailing SS3 prototype. made 387rwkws @ 24psi In fear of snapping con-roads it was done on a short 9 sec ramp, so the curve on paper does appear laggier then what it actually is.

Car was having some troubles on dyno with poor fuel in the tank and the fuel not having enough timing in it. Car is going back on the rollers on tuesday for a retune and to fix any issues. Hoping to see just under 400 out of it

Car has been tuned again, had a crank angle sensor fault aswell. car now makes 350hp. still a bit shot of what i wanted.

running 98 ron

On 12psi max made 256.1 kw @ the rears wheels @6500rpm

Will get more but unable to set the timeing correctly as i don't have a lower timeing cover fitted as there wasn't one on the engine when i got it.

Once i get the cover will be able to wind up the boost to 16-18psi.'

Will upload dyno sheet on Monday or Tuesday.

Something not right with my setup, not making as much as it should.. I've since changed the restrictive Blitz Nur exhaust over with a straight through 3" system so hopefully could make a bit more.. yet to re-dyno

Nistune (car has run with auto base image for around 2 years finally figured out that it was supplied incorrectly and just re-imaged)

Tidy up tune with Jez to check what if any WOT mapping changes were needed after installing the manual image. It is anyones guess what Nistune is doing under the surface. Plus I wanted to work more on getting the car off the line. The Stagea bogs down quite easily unless you give it the beans off the line. Changes made to very low load fueling and VCT has sorted out these issues.
