My Gcg Hiflow Results

[paulr33]

The one thing that no one has seemed to mention throughout this thread is "why the hell would your tuner take your care to such extremes when he (or she) knows it is dangerous to the engine at that point"

330rwkw or hp; from a stock set of injectors... I'm no expert but I'm going to ASSUME that at this power your injectors would be at 99.99% duty cycle. The tuner would be able to see this if they were doing their job correctly; shouldn't they stop and warn you that your car could blow up?

When I got my car tuned (has pretty much everything except for injectors as well... the tuner stopped at the first instance and he warned that if he kept going for more power; I ran the risk of blowing up my motor. Even when I asked him if there were any other ways of doing it; he insisted that the session ended and I went away and got injectors.

I wonder who tuned this car and why they would keep pushing it despite the apparent risks.

I believe this was back when a certain workshop believed the wolf had superior fuel injection control and was able to flow more fuel through standard injectors vs say a powerfc using the same stock injectors. so the result was they kept trying to get more and more power on stock injectors and it went bang, like everyone said it would

hey guys sorry for late reply. i dont have the internet at home so im at work currently. will post dyno sheet up on weekend for u. YES the figures were extremely lean. over 13:1. It was done at hiu torque performance dyno day. i told him to watch the air fuel ratio coz i'd not had it dyno'd since after run in but the a/f's were way too lean. it run about 11psi then spikes to 15 at 5500rpm you'll see that in the gragh when i post it up. run was done bout 3pm in afternoon and was in 3rd gear. i havent changed injectors on it n its still running stock management(that i know of) although i dont have a speed cut anyway for some reason. theres always critics so i dont mind the critisism. anymore questions i'll be happy to answer

Hey just chucking this up for shane,

I was at the dyno day with him at hi torque, was quite suprising to see his power he put down.

Guys put the ID: down as r34 lol we wish but its his r33

Shitty boost control.. Much more mid range in it.

hi guys, a bit off topic but how would you compare the bosch 040 to the walbro in terms of flow?

How far can you puch the 040 in kw's?

[Evasion]

you call that a "bit" off topic lol.

number two injector has givin up now. put a sard fuel pressure reg on it n bumped pressure up, was good for a day now misfires when increasing fuel pressure. done all tests so rail out and injectors to come.

and possibly the worst graph known to man, if thats what you wanted? .... short of that one in the KKR thread though, thats even better and it HAS an ECU

Although, the boost delivery is extremely interesting as its only got the same power as the stock turbo for what, 85% of the RPM range, it only peaks in the last bit, so essentially the car really isnt any better than stock at all.

I suspect thats to avoid the mid-range shutdown that most people get when a car ramps onto boost with the stocker ECU. Its simply making a peak figure.

Mid-range = nothing

Low-end = nothing

Extreme high end = power spike

Which is totally uncharacteristic of the GCG hi-flows.

I bet if taken to the strip, the car wont run a much better time than that with a stock turbo

Got any figures/graphs from any of the other cars that day?

yeah i know im trying to figure out the boost spike issue aswell. boost controller was all the way down, suppose to run 7psi but it cant hold it. was at hi torque dyno day bro im not making it up. why;s it so hard to beleive?
