Also, I'm still working on things like chatbox, etc so hopefully those will be working in the next week or two.

I've been brainstorming a neat little setup...(those with NIC cams please chime in)

I'm currently planning a build that will mainly consist a gen V swap, NIC cam or similar custom cam design with supporting valvetrain, and meth. Besides the valvetrain the heads will remain stock, and I'll obviously not use an IC. I'm really interested in seeing how much power I can get with this combination, I'm hoping for at least 330whp. The meth portion will be a duel nozzle set up in the lim, and with the power I'm looking for, the nozzles will either be 4 or 5 gph. I know the NIC isn't the most popular cam here, but from what I've seen the gains are solid when backed up with a good tune. Pulley size... Well I'd have to find out at the end of the build to see what I can properly run, but I don't see why I couldn't run at least a 3.0 pulley on this setup.

SLP headers, open cone intake, properly sized plugs, and a P&P lim appropriate to flow well with stock non gasket matched heads will also be on the car. I'm also currently hunting for 42.5lb injectors, and I'm not going to run E85 because I think there's only one or two pumps in CT, and they're not anywhere near me. Thoughts?
 


this is going to be really similar to what i've had cooking in the back of my head for a long time. except im going to have a baller set of heads and hopefully a NIC-esque cam (higher lift to use the head room) with meth. most likely with the RIGHT TUNE you'll breach 320whp or so, but it really depends on what you do with it.

i am going to be hunting for the smallest pulley possible on stock timing, whereas you'd probably be better off going for more timing and keeping the boost down a little more.
 
I like your way of thinking. I'd go for a nice pair of heads, but I want to overhaul the suspension on the car. I just want to see how far I can push this set up, down the road I'll pick up some form of stage 3 heads or something. I assume your latter comment is because I'll be able to only have so much boost that the heads will become a major bottle neck, hence the extra timing?

As for valvetrain stuff, I'll be rocking a double roller, Manley steel retainers, and I'm thinking of using L76(g8 GT?) springs instead of the LS6's, and do I really need the OE-R lifters? At this point in time I really don't see my car being a rev monster. I made peak power at 5300~ rpms when I had the 3.4 sc pulley and the intake.
 
Skip the OE-R lifters. Use the LS7 replacements. Reason being is the OE-R have a small preload and the stockers have a huge preload. What this means is if you put in the OE-R's you should measure each rocker and get custom pushrods to keep them from clacking etc. (common) The LS7's are the current replacement for our stockers. Purchased as a set of 16 from most shops, they'll be cheaper than buying the 12 pack. The stockers having a great preload will adjust themselves (simplification of what happens) to absorb or give if needed for the valve train.

Going with a cam like that, I'd suggest either 105 or 130# springs. The double would only be needed on 130# springs or higher.

my power comes on around 3500, and pulls pretty nice up to 6k fyi
 
Thanks Bill for the info, I'll look into getting the lifters.

TEK- why are you just running a 3.5 on your setup?
 


On the double roller, machine the crank gear chamfer to match a stocker. The Aussie chamfer is different. That stops the deflection that causes the crank gear to hit the oil pump cover. It's one of the things I dislike about ZZP, Zoomer was in that thread and the discussion with Rollmaster about making a US crank gear and they never changed it on their site to either be a machined gear or any other info beyond "put on a machined pump cover". Don't need a different cover, you need the chain to be aligned.
 


Just curious.

What is the advantage using meth injection over turbo. Seems like a lot of variables to achieve what is so easily attained with turbo.
Cost maybe?...just novelty?...or just for chits and gigs?
 
the meth train nowadays is more of a novelty thing, i suspect.

a turbo setup is cool and all, but some of us just want to stick with the m90 and see where it takes us. big power, no doubt go turbo. but if you wanted to run a heads/cam m90 setup to make a good amount of power and just run it as is then that's always a good route as well.

meth will help with dropping pulleys and being able to raise timing. chemical intercoolers have been proven in the right application all over the place. now, it takes the right person to make it work correctly and the tune will constantly need to be tweaked because of environmental reasons, but it does what it's supposed to do when installed and used correctly. you can't drown the cylinders in meth and it's best used as a fine mist to help cover up random detonation spikes. i previously used meth as a 'secondary fuel' and more of an octane booster and it worked for what i was doing, but the car always felt very doggy because i was most likely spraying too much. it's best used in minute amounts to cover up problem areas rather than how i used it.

Tinkerers!

I would combine the meth injection with turbo...sure it's been done. No problem hitting 450HP with the correct setup?
 
meth/alky is usually best suited for turbos because you dont have to blow it through the power adder in most cases and usually ends up being more effective.

however, if you read above the OP is hoping to tap into the LIM in a couple places (i am hoping to do the same thing) and spraying post blower. if you can effectively mist the LIM you should see some pretty good gains out of it (once you find the correct spray pattern and size for the nozzles, of course).
 
I don't believe there is enough length between the blower output and the runners. Cylinder variation will most definitely be a problem.

You'll definitely have to use multiple nozzles...preferably at the runners in the heads right next to the injectors. 6 nozzles is a lot of work though.
 


i was hoping i could mock something up and figure out a good place, but two nozzles might do it well enough. there are two recesses between the runners on each side of the LIM. since they are offset from one another they may just do what you want based on their positions. however, if possible i would love to do six small nozzles directly in the runners, but it may take some effort to get them in there without interfering with other things, mainly the fuel rail.
 
Now you guys got me interested in this chit. Just what I need, more things to think about.

Go for the 6 nozzles in the runners...takes all of the guess work out of it. You won't have to worry about spray pattern either.
A good pressure regulator would make things more consistent and easier to tune.

Flex line won't interfere with fuel rail or anything for that matter.
