Jackass w/ LS9: original build and new Jackass 2.0 updates!

[Payton King]

This question is going to seem to come out of left field...what injectors are you running in both Hell Fire and JA 2 ? I am looking for an injector to support 800 hp NA and did not know if the GM injector is up to the task.

I have looked at this injector as well

Thoughts?

I'm pretty sure he's using fire hose nozzles. I could be mistaken though.

Right?!

Are you thinking 1.5" NST or 2.5" NST though?

Probably the "up to 350 gpm turbo nozzle" ... with twin pistol grips... times 8!

Carbon Ceramics and an LS9??

For E85 compatibility (and flow requirements) JA2 will use Injector Dynamics 1300's.

Same injector we used for Thomson's Corvette engine (near duplicate of Hellfire with E85).

Best injectors I've used yet for these high-power engines. Great control at lower flows (idle on gas) and still have capacity for peak power on E85. Not to mention they provide the injector characteristic calibrations.

They are Bosch Motorsports developed parts sold exclusively through Injector Dynamics. Not a cheap date - but they work exceptionally well.

800 NA is beyond capacity for all production GM injectors. ID800 is large for 800 NA. ID725 better choice.

Not to get this thread derailed too much or off-topic, but what is the highest flowing GM injector? Stock Ls9?

Thanks for jumping in Dave. I am sending you a PM.

Common LS injectors sorted by size (flow rated @ 3 BAR or 43.5 psig)

So yes, LSA/LS9 injectors are largest stock GM port fuel injectors.

The plan is coming togther. Matt at Sled Alley is working on JA and Thomson Auto has the short block just about done.
