91 gtr

[Super_Dude]

I'm finishing up the install of a HFS-6 on my 91 skyline GTR.

The car is has a single turbo (gt4088r) and I'm shooting for 600whp on pump gas with x6 800cc injectors.

I've got x6 .3mm jets and I'm concerned that it might not be enough. I will be running 50/50.

Also, I'm pretty confident my setup can get very close to 600whp without the WI but I'm installing for extra safety and cooling. is 50/50 my best bet? would straight water be a better option for my situation.

Thanks

For 50/50 you need about 900-1000 of injector, I don't think the .3mm jets are going to get you there. You best Bet is always to test the jetting into a container and see what it is actually spraying.

50/50 is a good starting place. Each application is a bit different. You can run straight water, but it does require a strong ignition, and preferably higher octane fuel as standard.

Is there is an issue not having enough meth. Would my results not be as good or can it potentially cause engine problems if I'm not spraying enough water/meth.

For instance, if running 50/50 at 20% to fuel and you can run a 100 octane race map on this with no timing pull, then not spraying enough may cause knock issues and you would have to pull the tune back some. It's easier to dial back the jetting a little on the controller then not have enough.

Just wondering if anyone could draw me up a diagram to make sure I wired it correctly.

I believe there is a GTR diagram on the HFS-6 forum.

I searched before but didn't see it for some reason.

Thanks a lot Richard

I will throw it up incase someone else finds this thread first.
