its all in the tune!! motors the people have said cant take the boost have with a proper tune. you can spend all the money in the world on a motor but if you dont have a good tune it wont mean anything. the same goes the other way if you spend money on a tune and it is precise than your motor can do wonders
I've seen race cars do around 120% duty cycle on injectors. Its not ideal but you can push them past 80%, your more probably right on the accuracy none the less.
WOW! that is SERIOUSLY stupid... who ever owns this car is walking on a thin line... first of all you should never push injectors past 80% because near the top they are less accurate and more likely to lean out. Second, 1.2 bar on stock injectors.. holy crap. this guy is brave. he must check his oil for shards of metal after every drive.
I dunno. Those guys over there have been tuning these cars since 89 so most of their tuners might know what's going on. Canada has some 7 years of tuning these cars. I see lots of builds like that over there. A razor sharp tune doesn't have to be rich at all even. Some of the best tuners say a tune is crap when there's black smoke but in canada, most higher powered cars puff when going into WOT. Anyways, I'm sure he's fine.
This is pretty much what R34 N1 aka -7s aka SS would fetch on a good tune and correctly reading dyno I think.
SAU and GTROC seems them in the 400whp most often when closing in on 1.2 bar
99 R34 GTR non-vspec
Unopened engine. Done approx 70K.
100K service done with all OEM parts, including water pump, timing belt, bearings and seals.
Adjust Cam gears
Garrett -7s
Stock injector
Stock fuel pump
Stock air box with high flow air filter
Stock intercooler with full HKS hard piping
Nismo fuel regulator
Spitfire Coilpacks
Iridium spark plugs
EVC 5 boost control
Power FC
Stock dumps and manifolds
Full NISMO WELDINA NE-1 Exhaust De-Cat
Koyo Radiator
EXEDY hyper multi twin plate clutch
Tuned @ Racepace
Pulled 288.7 RWKW @ 18.2 psi, on BP 98. Just under 400whp
Bought Sard 700cc and Bosch 044, but told no need to install them as I had -7 only. Stock injectors cycle duty @ 98.8%. Knocking rarely exceeds 25 under the sun. Feels hell a lot better to drive.
