Victor Jr setup with Air cleaner
Victor Jr setup with Air cleaner Hey guys I am pretty new to the world of LS1s and just found out recently that you could use a carb style intake while still staying EFI, which is what I would like to do. I am planning on going with PRC ported ls6 heads and a bigger version of the TREX cam and I am hoping to rev the engine to 7000-7200rpm while racing. So I have been looking long and hard at different intake setups.
These single plane intakes look really good because they seem to be really strong in the top end which is where I am looking to make power. Even with very little torque it will still be enough to get the 2500lb vehicle this engine is going in moving quite quickly.
What I want to know is if I use a victor JR intake what TBs can I use?? What type should I look for? and where would I put the MAF? So I am wondeing how you guys did your setups. I think if I want to use a MAF I have to get a sheetmetal elbow from intakeelbows.com but I'm not sure. I know I will probably have to cut a huge hole in the hood but I'm not too worried about it.
Also I know when everything is said and done I will probably spend as much as I would for a fast intake (which I think is overpriced) but I figure this is a better match for what I'm looking for as well as better for my future mods which include a nitrous plate system (which would you guys suggest for up to a 250-300 shot) or a d1sc or F1c procharger.. I am basically building this car as a street racing terror/ quarter mile machine.
Btw if I do end up running this single plane intake with a huge cam some nice heads with a huge tb or a 4 barrel tb and a huge air cleaner... wont a stock 75mm MAF be a bit of a restriction on this setup and whats the cheapest solution to fixing that issue.

It wont be a stock style setup its going to have heads/ huge cam and nitrous.. possibly a procharger later

I'm running the Victor Jr with an Edelbrock 1000CFM 4 barrel T/B. I'm also running a Speed Density tune so I dont need a MAF. The edelbrock T/B uses the stock TPS and IAC so all the factory connectors fit. You will just have to un wrap the loom and re rout things a bit. I machined the base of my air cleaner to take the stock IAT sensor.
A few other things need re routing. I connected the MAP sensor to a vaccume port on the T/B vi a short length of rubber vacume hose. The purge solenoid I relocated to the trans tunnel and connected it to a port on the side of the manifold. The PVC connection I just re routed a bit to another vaccume port on the front of the T/B
There's another pic of this on the forum here but I'll post it again
Cheers

Thanks John.
I should have some Dyno comparison figures for it soon. I've just pulled the manifold off and loaned it to a friend of mine. He has a similar engine setup to mine in his Cobra. He's tried the LS6 Manifold with a ported stock 75mm T/B. An LS2 manifold with a 90mm Holley T/B and is now considering a 4BBL setup like mine. We figured try it out before buying one and see if it makes any more power than the previous manifolds.
Cheers
