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

[formula88]

With the downbars removed the AM subframe was lowered with a couple floor jacks.





And the new DSE subframe installed.

Mark pocketed the cross member near the RH engine mount to provide clearance for the AC compressor.

Next up, a mockup block, heads and blower were installed to check clearance to the DSE wiper motor.

Mark is Sled Alley going to make the changes to LS1 style engine mounts for noise and vibration as Hellfire?

We've used Concept One A/C compressor mount for the LS9 and it gave us enough clearance

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.
