Same here. I'm not worried about the judgement of members on here. Just looking for insight and knowledge on porting the IM and possibly an air to air system (although maybe not right away as I have some tricks up my sleeve hopefully with a custom option B tank).

I look at these projects as learning experiences and a chance to do some different stuff and try new things. I have done some of the basic cooling mods but I want to address the intercooling system without using meth injection so it leads me to porting the IM and possibly the air to air setup.

 

Meth was great for me cause it let's my tvs have fun

 

I'm sure it's great but I just don't like the idea of the fun running out! LOL.

 

not everyone did man

 

Getting withing a few degrees of ambient is pretty much impossible without meth was my issues. Getting within a few deg of iat1's is more believable though. My real issue with the air to air setup is that it defeats a good chunk of the gain from going blower over turbo because it starts to negate the throttle response advantages.

 

The throttle response would be a problem for me if it isn't that great with the air to air setup as I autocross the car. I may have to stick with porting and single pass and my intercooling system mod.

 

I don't have numbers to back it up but my throttle is on point. No lag in power or anything. The system works very well.

 

You might not notice, but its there. I'm still on the fence if adding 2 feet of pipe between my tb and my filter is worth the trade off between more power and worse response.

 

I think ill start with the port and see where it goes from there. If I'm not happy with the cooling I get from that and my custom option B setup, I may end up attempting the air to air.

 

freds air to air has an advantage that hasnt even been addressed to date, it allows the maf to be mounted in the pipe returning to the tvs, making it possible to put a waste gate in the piping leaving the intake on its way to the fmic. you could run a 2.5 pulley on a tvs, set the waste gate to 22 pounds and have 22 pounds of boost avail from 2500 rpm to 7k. talk about a awesome powerband. as it is there is no easy way to control the boost on an sc, you have to limit pulley size so that the top of the power band doesnt blow the motor apart, where as a turbo can make whatever amount of boost you want. the air to air design allows you to do that on an sc car, which is awesome. not to mention the prototype of freaktas car is just a first run, theres a ton of improvement room to allow for more airflow.

 

But that is a very inefficient way of reducing boost.

 

the only other option is a cvt transmission in place of the snout of the sc so you can directly control blower rpm seperate from engine rpm. some piping and time with a welder is a much easier way. add to that the fact that an electronic waste gate can be changed on the fly so you could literally dial the boost up or down.

 

take a guess....

 

maybe..... lol what are you running through those lines?

 

So you had euthanasia do your work. I have one from him too. I just got installed but I have not done any driving yet.

No.

That would probably require a custom snout.

 

its what eaton is working on for the next gen blower, a cvt snout so the blower spins to desired boost levels as soon as the motor starts running. it also offers the advantage of being able to wildly underdrive it when you just cruising to reduce the power needed to spin it when your not in boost. its 20 years overdue at the least but its finally going to happen. but for now, air to air with tiny pulley, wastegate and relocated maf is whats available to make it work.

 

SKcobalt, I should have taken you for a ride in my car. There is no "boost lag" to speak of and John Powell can attest to how well the cooling works. However on an M-62 I would worry that the volume of a air/air system would have a negative affect on throttle response. This spring I will be working to try and minimize the volume of my system to maximize the efficiency.

 

I am very interested in what you guys got going! Next mod is probably a single pass w/ port job...

 

What is it that you have going on ?

 

Not sure if I entirely understand your question Freakta. If your wondering about my LIM setup here is the thread.

M62 After 12 hours of racing, no meth

M62 after 4 years on the street with meth injection on 73 mm pulley


laminova in 3 d? dunno

 

ya thats good for them. my meth is injected directly into my head, way after the tvs, ill never have that problem

 

I was considering Meth before the charger just to cool the charger down since I have a 2.6 on it...maybe not the best idea then...but i have thinking about that since i have been on e but most people said it wasn't worth it and now some are starting too...weird how **** works

 

if you just want charge cooling, run water. Though if you have city water or hard water I suggest you spend the extra couple bucks and buy distilled water, or at least something like poland springs, no mineral water or anything with added sodium.

 

Idk what size gph to use...
