Man sounds like your trying to build a space shuttle out of a cardboard box. Keep it simple, First that turbo is way to small for a 408, second You have to change the entire rear section of a rearmount to make good power. Also a 50 shot at the intercooler would loose its power befor it reaches the throttle body, The most you would get is a cooling effect wich is a plus, You would pick up alittle power also. Using meth along with no2 just adds more **** to fail. If the meth fails while your spraying no2 its going to throw your tune off and **** may go pop. Im not saying it wont work but its just to many systems to watch. But If your stuck on the no2 Ideal I would look at a stand alone fuel cell and us some vp 105 race gas. That way if the pump fails no2 wont spray and your good. Also if your stuck on the rearmount take a look at the tc series 76/78 mm turbos or the gts 76/ 78. My numbers are from a rearmount the highest numbers where 813/ 710tq on 17-18 psi afr 10.3 with meth. 4xx ci motor.

 

Yes I think you're right. I will be putting 2 pumps in the tank and a bigger feedline. Depending on how much a turbo kit is from Josh. I might sell my sts kit and get a front mount turbo kit off of him. I need to make my mind up on one or the other between nitrous or meth. I know meth will let me run more boost. I have both kits already. The meth kit is new and the nitrous kit is on the car. So I might sell it. But I will wait till I get it on the dyno and see what one does the best. I think I will go with a bigger turbo.

Do you know if you can put subframe connectors with the rear mount kit? I was told you cant.

 

Keep it simple. Ditch the bottle and turn up the boost.

 

I've had discussions with nitrous outlet and many others, I agree with Frost about it being a crutch for a poor system to some extent. Here's a couple of examples of why I'm going to run nitrous at times. My car is set up to be fast from a dig, nitrous will help from a roll, 3.73's and a high flashing converter make it hard (slow) to put a load on the motor to spool the turbo from a roll. With a small shot of nitrous you can leave it in 4th and let the car pull.

I would run it just because you want to, I mean if your already running a turbo all logic and common sense arguements have already been defeated. I haven't met a person yet that could explain why they needed to turbocharge their car.

 

Because god gave us turbochargers, so we should use them!

I'm going to run some nitrous on my truck just to lite the turbo off the line. I want to bracket race some next year and I need something consistent so it will 60' the same every time. So this winter I picked up a used N2O setup and a used 2 step and gonna try both of them to see how well each works for launching. Trying to brake boost the launch is very difficult to time it to get the same boost every time or to even get to the desired boost level before the light turns green. So I'm thinking with N20 I could just stage, bring it up against the converter a little bit, then launch and spray a 75 shot from 3000 to 4500 in first gear only (I have a 2800 stall converter). That should lite the turbo and launch pretty consistent every time. We'll see how well it works come spring.

 

See that's what this one guy does that I know. He has the meth added in on top of the nitrous. He runs the nitrous and meth to the 1/8 mile mark. Then he turns it off the nitrous and runs the meth on down to the 1/4 mile mark. That is kinda what I am wondering what ppl think about.

But some are saying keep it simple. So I am haveing trouble makeing my mind up on how I should set it up.

 

I know of a setup the guy dynos 6xxHP no spray and gets 175HP from a 100HP shot. his engine has a 9.5-10 cr w/over 2 bar plans for going 3 and he spray the full length of the track. runs 9s something its a small tire and stock rear chassis. But its a track only car and he runs a exclusive blend of fuel id bet its close to pure 110 or whatever they highest you can buy. the nitrous is tuned with a stand alone unit its a complex duel pump system ect ect o ya its a foot brake car too.

anyway so what are you going to use the car for? when thinking from a design aspect i start with functionality. having the meth and nitrous to come on and off in stages does add complexity to the tune, will you be using the car at all without these features? and what will happen when they are not being used? (can you operate safely without them) .

Next i always weigh the options, I like more myself i think its possible youu may find a few ponies some where with both meth and nitrous i might even try both kits at the same time if i had this set up. When you get down to it though i think the gain will be minimal. if its a track only car why not just spray the length. It just isnt worth the complexity for the hp itself I say if its a track car,u got the juice use it. spray the length, and if u need to be slower u can always take you fanger off the button.

Lastly i consider the badass-ness, the only category i think the use of both kits would win in. If you think it looks and/or is badass enuff then just put it on there and use it anyway. Im pretty sure u can standalone a fuel system for the nitrous run it all the time with a return "wet" single fogger near TB. Most standalone pcms allow for a tune that alters the map under switched 12 I would use this during the alchohol phase. Timers and controllers for example work, like the nos progressive rate controller works just as well for both kits. The more control you give them the less you have for example in a heads up car i might see a 3 stage kit and the guy has 1 on the wheel 1 on the shifter and 1 on wot. Thats a bit exessive id say but it works for him cause he only wants to run as fast as he has to. If you use controllers for both you will just mash the throttle and have just the option of shuting it down by lifting the throttle. That is something to consider in the design of the setup.

now that i think of it you kno what u need next another turbo, and a lenco and back-half or full tube chassis, big tires... have fun
