Awesome man, I may go the same route with the Jr intake. I picked up a M122 from a GT 500 not to long ago with plans to install it on my Firebird in my sig. I had just planned on making a low profile sheet metal lower without an IC. I run E85 anyway. One of my issues was the injector bungs, which you seem to have found a way around without issue. Thanks for the inspiration.

Id advise against not running an IC. My M122 will boil water off its case after 30 seconds of run time. Not something you can deal with

I'd love to get some dimensions for that blower manifold. It'd make a really sweet budget blower build for my ls truck.

This! Running a PD blower without an IC is just asking for dismal results. IAT's will spike so fast you'll be pulling timing out and not making any power.

E85 is a whole different animal with high IAT's. I am not worried about it, and if I really need to I could run it on E98.

Made a flange for the inlet and mocking it up. My grandfather passed away yesterday so there will be a short halt, but mid week I will be back at it with more updates.

with the stock fuel rails, what did you do with the crossover tube? that's my only concern with my setups, but it seems you've found a way around it. just curious also why you chose to use a lightning blower with the top inlet, will there be any hood clearance concerns?

Thanks guys.

The lightning blower was aquired by trading parts. The cobra blower looks better on paper but has its own set of problems.

The fuel rail will hopefully not be a big deal, weld plates over the holes from the stock crossover and weld fittings into the back of the rails, then put a "Y" into the supply line.

Nice build bud, but I cant help thinking how the cobra blower would have worked a lil better for ya in this situation. I was told the cobra blower is a little bigger in size as far as air movement is concerned, not in actual size. BTW I have owned both (01 Lightning and 03 Cobra) and am aware of the physical diff between the two Eatons. If you could shed some light on the subject of why you choose the L blower Id apreciate it, others considering a build like this might too.

Sure. The blower sits low on this manifold, you may notice how the fuel rails are halfway up the blower, the inlet on the cobra blower would interfere with the rails. There is nowhere on the pass side to route an intake outside of the engine bay to get "cooler" air as the A/C accumulator is takking up the only path and I am not getting rid of A/C. These are problems that can be overcome, but I didnt need to overcome them.

more progress
