First PFC tune May 06

Matt Spry's 237rwhp

Allstar same day 276rwhp

Mercury Motorsport the next day 296rwhp...

All with in 24 hours on the same tank for fuel and all at similar temp's...

Take your pick???

Matt's dyno does not have to be accutate. His workshop is a temple of tuning. He simply uses it to mark gains from start to finish and of course to spin the wheels for tuning purposes. His setup is not for power runs or for dyno days, its simply a tuning tool.

i was just in at matty sprys on friday and i spun up 165 vs 195rwkw at mercury a while back

he said he had new software, so was unsure how much different it would read

car still feels the same as when it was 195. .. . . .

Confuscious say a man with 2 watches will never know the exact time ;)

I only use the dyno to make sure my car is tuned/running safely. Real power is to be measured at the race track. Regardless of how much power you have after a few months the car will feel like a snail again and you just want more boost :)

    • Is it alright to top up with just another green coolant?
    • thanks GTSboy. My confusion at the moment is i am trying to locate the ignition, ECU battery power and the ECU negative The closest thing i can find is the for the S15 on Page 8 of the Wiring Specialties web page https://drive.google.com/file/d/0B9F33_M_GgENQnZ6STMxVmVNd1E/view?resourcekey=0-eZ4nNRwRoqa1qvKlWWHm8A I cannot find the same diagram for the R33 RB25DET Series 2 dash plug pin out.... Do you know what the Pins? or know where i can find the same pinout diagram for the RB dash plug? Thanks for the advice on the box... i like a 6 speed so might be on the lookout or the box now.. a topic of discussion for another post...
    • Will have a look at that. I cant see any leaks 
    • Put another overflow bottle (ie, a 1.25 coke bottle or similar) under the overflow hose and see if it is being pushed out there or if it is disappearing into the engine.
    • Staring on a stand is no issue. You just have to wire everything up, give it fuel and cross your fingers that the stand is robust enough. Arranging the inlet plumbing is often the hardest part, without any surrounding structure to hand some of it from. No need for coolant if you only want to run it for <1 minute. As to the gearbox - I think the little Aisin box is a bit stronger than the other small Nissan boxes that went behind SRs, but I wouldn't be too keen to test its limits with the torque of a boosted 25. I don't know if you can retain the box and the tailshaft. The box won't connect to the RB without an adapter of some sort, which is either a plate that will push the engine forward (which is not good for fitting it into the bay's available space) or push the box back, which messes with the box position and tailshaft length - OR - cut and shut work on the bellhousing, which is a long way from "least modification". I'd be buying a new 370Z 6 speed or similar, doing what has to be done to that to make it fit RB (ie, cut and shut bellhousing) and the requisite tailshaft custom/mods.
